Oil Tank Replacement Services
Comm Tank provided a detailed competitive quote in writing to replace my oil tank. They were able to work with me on scheduling to job. Big Deal. That's business 101. The key is their Team. They showed up on time and cranked out the job like their lives depended on the quality and timeliness of completion. All without a drop of oil on my rugs. Mel and Italo are professional, knowledgeable, and considerate. They were also patient. I am an old man and ask a LOT of questions and really appreciated that. There were less expensive quotes, and God knows I'm a cheap SOB, but the reviews I read made a compelling case for not going for the lowest quote, instead opting for demonstrated quality work and peace of mind. Money well spent.
We just had our 65 year old Oil Tank replaced today by CommTank. They did a fantastic job. The salesperson Santiago came last week to look at our old tank, explained everything to us about what would be done and gave us great advice about which new tank to go with for our needs.We got a few estimates and CommTank was by far the most professional.The crew arrived promptly, worked efficiently, neatly and had the Fire Department come and inspect before they left. Santiago came as well to show and explain everything we needed to know about the new tank and how to register it for the excellent Warrantee the manufacturer ROTH provides.Then new tank is upright takes up less space and has a clean stainless steel exterior. They replaced sealed and painted the new outside pipes and reinsulated the exit holes.We would highly recommend Santiago and CommTank for oil tank replacement!
I had an oil tank removed because I switched to a heat pump system. The oil tank was in a mechanical room that was small so taking the tank out had to be done carefully. I wanted a professional local company that specialized in tank removals. I researched and found CommTank. I read through a lot of reviews and was very impressed. Santiago, the sales rep, came to meet me and he spent the time I needed to understand the process and give me confidence that it would be done right. I was again impressed.Today was the day of the removal and I am so happy. A team of three guys showed up and Santiago. They were amazing! Hardworking, professional, careful with all. And when done, cleaned the area - you would not even know an oil tank was there (and my oil tank was over 20 years old!)I wanted to add my 5 star review to all the other great reviews. I highly recommend CommTank for your oil tank needs. They are the best around!
Price was half the first quote I got. I was able to schedule the removal within a week. The crew was here on time and had the tank out in about an hour. No mess, no smell. Excellent work
I had a pinhole leak in my oil tank discovered by my HVAC company and needed to have it replaced. They recommended CommTank. They were quick to send someone out for an estimate. I also contacted a competitor and while both were within a few hundred dollars, CommTank was less expensive. I ended up choosing them not only for the price but for their reviews and for their many recommendations on my town fb page . I’m glad I did because they did a great job with the install/replacement of my Roth tank and left the place as clean as they found it.At least in my town, after you have an oil tank replaced the fire dept calls to schedule an inspection. When they came out it was very quick and I said something to that effect and the lieutenant said “I see it was installed by CommTank. They do a great job and we never have any problems with them.” If that doesn’t give you piece of mind I’m not sure what will!
CommTank came and removed our tank after we upgraded to a heat pump system. They were responsive and easy to work with when scheduling, showed up exactly when they said they would, and were quick and professional. They left the basement clean and even put some powder down so nothing smelled like oil. Payment was easy via credit card and they were done in about an hour. Great experience and would highly recommend
They removed my old oil tank from my basement for a very reasonable cost and did an excellent job. Great response, super fast to schedule and they got the job done so quickly. They cleaned up very well after the work was done, highly recommend!
Took care of old oil tank. Professional. Clean.
I've used this company twice now. They are quick and awesome
CommTank changed out my old leaking oil tank with a Roth lined tank and I could not be happier with the installation. The office personnel were very courteous and set up an appointment for visit. Santiago came for the initial site visit and Carlos was there for the installation. Both were very friendly and professional, they did a nice installation and left the worksite spotless after the install. I highly recommend them and like the safety of having a lined tank with a leak detector if it is ever needed.Thank You.Tom
We were extremely happy with the service provided by Commonwealth Tank. We had 2 residential tanks replaced and everything was very professional and well done.
Professional workers. Careful and competent. Great guys! Highly recommended
Replacing my oil tank. Loving my experience, this is great professional team, they keep you up to date with any changes and show up on time. Thanks commthank for coming out here in the middle of the snow storm 🙌!
Just had a new Roth oil tank installed. Customer service top notch. Francesco and Melvin came to my house on time. Clean neat installation. Wonderful work done by these to men. I recommend Commtank.
Used CommTank to replace our 30+ yr old tank. Work was done as promised, professionally and at a very good value. Highly recommend !
Sanny and Sergio just left the house, and I couldn’t be more pleased with the work. Two large oil tanks, installed 20 years ago, are gone and it is like they never happened: the place is immaculate and there’s not a drop of oil anywhere - the tanks were carrying over 500 gallons of oil.Throughout the work, they were professional and careful, and very respectful. And these guys are strong and seem to love the work. Especially noted when it can be hard to find smart, dedicated people, Comm Tank nailed it.
We had Comm Tank replace our aging inside tank with a new Roth outside tank. They were personable, professional, prompt and cleaned up completely.They took care of installing a concrete pad for the outside tank and removed the old tank.We are completely satisfied and will highly recommend them.
They were very professional. Showed up on time and did a very nice job. Left the place very clean. I'm very pleased and would definitely recommend them!
Had an emergency situation and they were able to help me out ASAP. Very happy with the service and the job they did. I had issues finding a company in the busiest time of year for an emergency and yet I was contacted and helped immediately. 5 stars for great service.
Good people,good place for employment
Had to have two tanks removed from my basement. Old bulkhead was not accessible and only egress had 27 inches. They arrived on time. Cut the tank to fit the opening. No mess left behind or to clean off walls, stairs or doors. Thank you for outstanding service.
While getting a quote and booking the service was less than easy, the service was great. They were easy to work with, clean, and prompt. They got in and got out with the oil tank the previous owner abandoned in place. I highly recommend their services.
This company just replaced an old oil tank for us. True to the contract you agreed to with no surprises. The company has amazing service from the first call to the technicians who replaced the tank. They are a truly professional organization. The installation was neat and organized. They left my property inside and outside clean from all debris. If you need an oil tank replacement this is the company to call!
They were subcontracted by my mechanical contractor to drain and remove my oil tank. They were courteous and fast and cleaned up after they were done
Manny and his team were fast, thorough and professional. They pulled an oil tank out of our basement quickly and easily in about 3 hours, and left the basement cleaner than when they found it. We will definitely call them again the next time we need help.
CommTank saved the day for us, I can home from work and walked into the dreaded smell of heating oil filling my house. I went downstairs to see where the smell was coming from and discovered that our recently filled oil tank was leaking. With one call to CommTank they had someone out in under 20 hours to access the situation, Gui put our fears to rest and got us on the schedule for a replacement. When the workers showed up to replace the tank they were extremely professional and tidy. They treated our home like it was theirs and protected our rugs and floors from the messy job of pulling out a 50 year old oil tank. The workmanship and attention to detail that went into the installation of the new tank exceeded my expectations. They refilled the new tank with all of the oil from our old tank after double filtering it to make sure none of the sludge and gunk went into the new tank. I can't say enough about how satisfied I am that we chose them for the job!
CommTank replaced our old steel 330 gallon of unknown age with a brand new Roth 275 (with the 30 year warranty and $2M insurance). The quoting process was simple and included everything, and the people who came by to do the work were punctual, friendly, and accommodating, and they left the place neater than when they arrived. They made sure everything was running just fine before they left.Give CommTank a call when you'd like to replace your old steel tank, especially if it's of questionable age and condition like ours was. Why take the chance? We like the warranty and insurance on the Roth, not to mention the extra space!
Friendly people.
CommTank was an absolute lifesaver!We were faced with underground piping issues that needed repair and were told to bulldoze the rooms to remedy the situation.We were shocked thinking that this was our only solution.Fortunately, we contacted and hired CommTank. The crew excavated, repaired and replaced our underground plumbing with great efficiency and precision allowing us to return to our house in a short period of time. We highly recommend CommTank and are so thankful for a job well-done! They truly are miracle workers!!
Great overall, from Leury coming out to estimate, to timely installation by Francisco & Raphael. Tough job, we do not have bulkhead access. Neat, clean and efficient. Pitched fill pipes correctly. Thanks Again!
Amazing - came day after we called and removed an oil tank - Louis was amazing!!
Comm tank guys are great and a real Fast I recommend these guys. O and the oil tanks thay put in are cool
We were in need of getting a new oil tank after we had nursed ours for a couple of years. Call a couple of companies and had them come out and CommTank was truly the best! They were very proffesional, were timely and gave us more that one option of tank. Their price was good and every interactio I've had with anyone at the company has been amazing customer service. They came on time, worked swiftly and were done on time. And the bonus for us more floor space!!! Use CommTank if you need anything, they are great!!!
Our aging heating oil tank was need of replacement. So we did our due diligence and contacted (4) companies for quotes not estimates. (2) never called back. (2) responded. Leury from Comm Tank INC was the first to call us and we quickly setup appointment. Leury went over everything they were going to replace in great detail and answered all of my questions.The service crew showed up on time and were quick to remove and replace the tank and they were extremely clean and courteous.If I could give Comm Tank 10 stars I would. Not very often you find a company with this high of professionalism and caliber.So if you are looking for reputable companies to remove your old oil tank,I would recommend contacting Comm Tank INC first.
Fast, clean, professional, on time, and thorough. Not a job anybody really wants to do but they make it painless
I've hired these guys twice over the years. I had them replace an oil tank in a house that I was moving from in Framingham that was in a very tight spot in my garage. I was in the middle of selling my house and part of the inspection called for a new tank. They made an exception and came out right away, because of the circumstances; and replaced the tank with no mess and extremely fast and efficient. I was very pleased and so was my buyer. Thank you guys.My next experience with these guys was for a house in Marlborough. The house was built in 1959 and still had the original oil tank. Once again they came out did a great job replacing the oil tank, and its been working fine for 2 years now. I couldn't be happier. If you guys need an oil tank replaced I wouldn't go anywhere else. My only regret is that I didn't do this review earlier.See the pictures below. I only have one pic of the Framingham oil tank they replaced in my garage, and the rest are of the house in Marlborough. Note the neat job they did of installing the the oil feed line to my burner.
Everything about the experience with CommTank was awesome. The guy who did the estimate came in the evening so I didn’t have to miss work and the price was even a little less than I had expected( $2600 for new 330 gal. tank and removal of the old one/new burner line/new fill and vent pipes). On the day of my tank replacement the guys showed up on time and completed all the work in 3 1/2 hours and it looks GREAT!! Would definitely recommend to anyone.
Dealing with CommTank has been an absolute pleasure. Every employee I interacted with was professional, courteous, knowledgeable and helpful. They call when they say they will, show up early, and work efficiently. The work itself was meticulously done, and my basement was spotless when they left. Would 1000% recommend CommTank to anyone in need.
I just had my oil tank replaced by Comm Tank. The guys showed up on time, took out my old tank without any problems or mess. Installed new oil tank where we requested it saving us so much space for storage. Guys on the job were professional and respectful. Great job!! Highly recommend them to anyone needing a new oil tank. Thank you Kevin for fitting us into your busy schedule and getting this job done quickly.
Shaina who works there and her company are the best..They were on time and everyone who works there are outstanding .
CommTank did an amazingly professional, detailed, and incredibly neat job of removing our leaking 275 gallon oil tank from our basement, and installing a new one in our garage. We were so impressed with the non-stop emergency work Willy, Manuel, and Juan Francisco did for 6 hours straight into the wee hours of the night. They had a virtual workshop with them in their truck, and worked continuously under difficult circumstances drilling into cement to remove old, and then install new, pipes, and install bollards. They knew exactly what to do and how to do it, and when they were finished, they left the basement and the garage immaculately clean and beautiful. It was as if we'd never had the old leaking tank! We cannot recommend CommTank and these guys highly enough! This company gets 5 stars and then some....oh! And all this done for a very reasonable price!
5 stars for the quick, low-pressure sales process, as well as the workmanship. I took off 1 star because the crew that did the install didn't fully clean up the space and left a black mark on my otherwise pristine washing machine.
I needed to remove two oil tanks in my home and replace them. I contacted CommTank and they came out to review the job and provide a quote. After some review and shopping I found that CommTank was the best overall value and the most professional company.They showed up on-time, did an amazing job with the removal and installation of new Roth tank. The work was done extremely well and the area left clean.Thank you Kevin, Leury, Francisco and the entire team for a job well done!
Removed a 1000 gal in-ground Heating oil tank / and installed a 275 gal indoor tank. They did the whole job in 6 hours and at $3000 less than the other 4 Quotes I got.
Great work, very clean and well done. Very professional.
best company you could hire for tank removal.removed 3 6000 gallon under ground tanks. louis diaz was great to deal with. gave me a price and time line . crew showed on time and you could not ask for a better group of guys. everything went smooth and on time. i recommend this company 100%. dont bother looking any further. thanks again comm tank.
Comm Tank Inc. is 2nd to none I called them during a Christmas Holiday week as our waste water team discovered a damaged DAF tank. They cam out right away to inspect and put together cost and repair options for me. We were stuck... in this situation vendors normally try to mark up pricing. This was not the case with Comm Tank actually quoted a price and wound up working through the holiday and weekend to complete the task as promised after discovering it was worst than the original assessment. Kudos to these guys who were great to work with right through the entire process Kevin Hoag was very informative and knowledgeable and exercised great direction to his team. The guys that completed the onsite work provided great customer service. In all Comm Tank does what they say there going to do and stands behind there quality of work. They will be the 1st on my call list in the event we need a reactive repair like this in the future and also any preventative repairs as well. Thank you to everyone at Comm Tank INC.
Commonwealth Tank was recommended to me by the contractor that installed my new heating system. Their customer service/scheduling department was very friendly and able to easily work around my schedule. One the day of the removal, the team (2 men) arrived on time and were both very friendly. My basement was still pretty cluttered (recently moved into the house) and they were very careful when moving boxes out of the way. They were very professional and clean, and the job only took about an hour. When they finished, they had me look at the space to make sure I was happy with the work. The holes in the foundation from the fill pipe were removed and sealed neatly with cement, no oil had been spilled on the floor, and everything had been cleaned very thoroughly...they even used air freshener to remove the fuel oil odor. I highly recommend Comm Tank due to their on time arrival, quick yet thorough work, and good customer service.

Key Factors that Affect the Cost of Replacing a Home Heating Oil Tank:

The main factors that affect the price of replacing a home heating oil tank are the tank type, size, location, and proximity to your furnace (also known as a boiler, or home heating appliance).

All these key pricing factors are detailed below, as well as other required processes that CommTank efficiently performs with expertise and specialized equipment, to add value to your project.

Aboveground Oil Tank Replacement Cost Factors

  • Type of Replacement Tank – based on the tank’s location, required functionality and longevity
  • Size of Replacement Tank – based on accessibility and size of space available for the tank
  • Access to Current Tank – based on interior or exterior location, such as crawl space, finished or unfinished basement, garage, etc.
  • Amount of piping needed – based on the tank’s proximity to your furnace, and to the outside of your home for tanks located in basements, or the inside of your home for tanks located outdoors. Two pipe use types to be replaced are the fill and vent pipe (which connects to the outside), and the fuel oil line (or fuel oil pipe) that feeds oil to your furnace.  The tank, fuel line, and valves must also be brought up to current code standards based on regulatory requirements in NH and MA.

"Thank you, Kevin and Nelson for bringing warmth in my house on that very cold day." – Chantal C., Auburn, Ma.

Old tanks to be replaced

Other Required Costs for Aboveground Tank Replacement

  • Obtain Required Permits – from local and/or state authorities, for tank removal and installation
  • Pump Reusable Fuel from Old Tank – and filter it twice for use in the new tank, without losing its value
  • Fuel Oil Sludge Disposal – to safely dispose of sludge from existing / old tank
  • Custom Cutting and Threading of New Fuel Line Pipes – to fit the specific needs of your heating system

The Lifespan of Indoor Tanks and Outdoor Aboveground Tanks

Indoor oil storage containers do not last more than about 30 years, and often their lifespan is much shorter, according to the Massachusetts Department of Environmental Protection (DEP).

Outdoor above ground storage tanks that have been uncovered for 10 years or longer should be replaced, since these storage containers rust from the inside out, and cleaning or painting their exterior does not usually help to prolong their lifespan.  How old is yours?

Leaking oil tank

The Potential Costs of NOT Replacing a Tank

Property owners face a major liability from aging, faulty or unused heating oil storage containers. According to the MA Department of Environmental Protection, the cost to clean up an oil leak from a home heating system can range from $20,000 to $50,000, with some cleanups costing significantly more.

Any amount – including just a few gallons of fuel in a tank can eventually leak into the soil, which can contaminate groundwater and require remediation.  Soil waste cleanup can cost hundreds of thousands of dollars. The sooner a tank is replaced or removed, the better the opportunity to avoid the expense of environmental cleanup.

Heating Oil Costs Remain Constant & Represent Good Overall Value

When adjusted for inflation, the cost of heating oil has remained virtually the same since the 1950’s.

As you consider options for your home’s heating oil system, you’ll discover that CommTank is your best choice for replacement, installation or maintenance of your home’s heating system.

Aboveground oil tank replacement steps

Aboveground oil tank replaced in basement

The Steps of an Aboveground Oil Tank Replacement

Advance Work:

  • Conduct a Complimentary Site Visit –to discuss a property owner’s needs and goals; assess any site-issues that could support or impede the project; review the location and condition of the current tank, and review tank sizes and features that will ensure a quality, affordable tank replacement
  • Obtain Project Permits – CommTank will obtain all permits, saving you time and potential headaches. Homeowners in MA and NH are required to obtain permits from the local fire department for tank removals, heating oil tank replacements or tank installations.  We know the regulations and local requirements, and maintain excellent rapport with local officials.

On Site Work:

  • Cover all floors and rugs; remove doors as needed for moving tank into the home
  • Pump remaining heating oil out of the existing tank
  • Once tank is empty, stand it on one side, cut it in the middle, transport it to truck for cleaning
  • Remove existing fill and vent pipes
  • Pump out and remove old fuel line
  • Clean under existing tank, in preparation for new tank placement
  • Bring new tank inside, and assemble on site (install legs, valves, filter, fittings)
  • Set the new tank in place
  • Measure, cut and thread fill pipes to specific site requirements
  • May need to drill new holes through concrete or wood due to pipe height restrictions for existing holes
  • Install the fuel and vent pipes
  • Install the sleeved copper fuel line connecting the oil storage tank to the furnace / boiler
  • Inspect all fittings to ensure everything is tight
  • Pump the previously removed and filtered fuel into the new tank, filtering it again as it is pumped
  • Check the whole system for any leaks
  • Prime and test the system to ensure proper operation
  • Obtain final inspection from local authorities

Additional Steps for Outside Tanks

  • Install a 4-inch thick reinforced cement pad, at a diameter larger than the new tank – since a tank cannot be placed on grass or dirt.  This involves building a form, mixing cement, and letting it cure for 72 hours. A temporary tank is placed until the new tank can be installed on the cement pad, as determined during the initial site visit.
  • Install a Rain Shield – which eliminates the requirement for a shed to protect the tank from the elements
  • Install a Tank Tub – as required by some insurance companies, a tank tub is a polyurethane tub with cover, that functions like a plastic tub around the tank to protect it from the elements

Photo of oil tank replacement in garage with bollards.

Oil tank replacement in garage with bollards

Additional Steps for Garage Placement of a Tank

  • Install bollards to protect the tank – as typically directed per local regulations
Key Oil Tank Parts
  • Fuel Oil Tank Gauge (also called Heating Oil Tank Gauge) – is standard with all new installations
  • Whistle Alarm – is an overfill prevention alarm that alerts the oil delivery specialist that the tank is filled to 90% capacity when the whistle stops
  • Tank Gauge (or combination Whistle and Gauge) – uses a float inside the tank, to read the amount of fuel inside, to a close approximation of 1/8, ¼, ½, or ¾ full

Oil Tank Sizes and Options to Consider

CommTank professionally installs several types and sizes of heating oil tanks manufactured by the two most trusted and proven commercial-grade brands, Roth Industries and Granby Industries. Below is a list of each brand’s features and model sizes that we recommend based on the usage for which each tank’s size, type and design is best suited.

How to Choose the Best Size and Type of Tank for Your Project

Every home has factors that make one size, style or type of oil tank most appropriate. Here are some key factors to consider when choosing a tank for your residence:

  • Doorway sizes – how tall or wide are they, to enable tank entry   
  • Bulkhead availability – if no bulkhead, then tank must enter through hallways and stairway
  • Ceiling height – leading up to and within your basement
  • Finished or unfinished basement – for access considerations
  • Proximity to furnace – fire codes typically require a 5-ft. distance between tank and furnace
  • Length and pitch of driveway – for oil delivery considerations (distance and seasonal factors)
  • Single or Multi-family home – for multiple furnace and tank coordination
  • Garage – Fire department or local inspector must inspect and approve oil tank placement, and typically require installation of protective bollards

Oil Tank Replacement FAQs

A tank installed outdoor must meet current State codes for heating oil tanks. A steel tank installed outside must have a shed. Fire inspectors won’t allow the installation without one. A Roth tank with a Roth Rainshield cover is less expensive to install than building a shed and installing a Granby steel tank inside.

Yes, we handle both if required by the town. CommTank’s courier goes to each town office and pulls the removal and installation permits and our crew delivers them on the day of the oil tank installation.

If the current line is up to code then, no. If it isn’t, then we replace it. For homes with a slab foundation, the fuel supply lines can be installed in the attic. Additional fees may apply, depending on length of the fuel line and accessibility.

Yes. We paint all piping (inside and out) to protect them from rust and corrosion. We also think it looks more professional than unpainted steel pipe!

When switching from Granby to Roth it is common to drill new holes to account for the difference in tank height. CommTank plugs holes in cement with a cement patch and uses silicone to caulk wood siding. We recommend that homeowners hire a carpenter to replace wood siding, when weather permits.

Depends on the town. Our courier calls each town before requesting a permit and discusses inspection requirements. If an inspection is required, the inspector is called an hour prior to job completion. Or the fire department will coordinate a time if they aren’t available on the day of installation.

Yes, it needs to be installed on 4” thick concrete pad, whether installed inside or outside, to meet current code.

Typically 4-5 hours for a single oil tank installation. The installation of two tanks can be a full day job. Jobs that require bollards in a garage oil tank installation will be a full day.  Jobs that require the installation of a cement pad (inside or out) will be a 2 phase job. The cure time for a new cement pads is 72 hours.  Depending upon the location of the tank installation a temp tank may also be needed. Tanks installed with a new cement pad in an existing location require a temp tank. Tanks installed with a new cement pad in a new location do not require a temp tank. In cases where the tank is installed in a new location, the crew will install the cement pad on the first visit, then return after 72 hours (or whenever is convenient for the client) and install the new tank.

Most states allow a maximum of 1,325 gallons to be stored in a single family residence. For homes with difficult access points (steep hills or long distances to the fill pipe over lawn and patios) the homeowner may choose to increase capacity to 400-gallons with a larger Roth tank or 550-gallons (2 Granby tanks connected ) to minimize the number of delivery. Winter deliveries can be difficult for fuel companies because of unplowed driveways and paths to fill pipes located behind a home. Reducing the number of deliveries per season may help reduce snow clearing required by the homeowner.

We have seen oil tanks installed with piping connected in series (single fill and vent pipes shared by two tanks) that have led to leaks from the tank top or leaks from tank welds that have burst during fuel delivery. CommTank recommends installing oil tanks with separate fill pipes. This will ensure that the tanks are never over pressurized during filling. Connecting vent pipes in series is acceptable, as the tanks are filled separately, and will never develop back pressure.

Cement cuts in floors are part of our installation fee. We will remove old lines and use the current trench if the old line was not up to code. CommTank’s project supervisor will check the distance between the new tank location and the furnace during a site visit. Extra fees may be needed if there is an unusually long run of supply piping.

The good oil (oil above the sludge level that is not cloudy) is filtered and pumped into a temporary storage tank. The sludge is removed and the oil tank is disposed of. After the new tank is installed, the good oil is filtered again and pumped into the new tank.

275-gallons it the standard or most common capacity. The amount of storage needed will depend on the size of the house and how frequent the homeowner wants to have the oil tank filled.

No, but lines could gel if temperatures are extremely low for long durations. If you have a long existing supply line then the fuel may thicken in the line and gel the oil.  We recommend covering the lines with insulation in this case. CommTank installs all our tanks with a supply and return line. This ensures the fuel is always moving.  We install fuel filters inside the basement and close to the furnace to minimize gelling because an uninsulated fuel filter is more likely to have gelled fuel when installed outside. For homes without a basement, extra insulation is required.  (This is common with mobile homes or ranch style homes without a garage.)
