A 138 gallon oil tank price typically ranges from $500 to $1,300 for the tank alone and about $1,500 to $3,500 installed. The final quote depends on tank material, whether it is indoors or outdoors, removal of an existing tank, piping work, and local labor and code requirements.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 138-gallon tank only | $500 | $850 | $1,300 | Tank type, coating, and construction affect price |
| Installed replacement | $1,500 | $2,400 | $3,500 | Assumes standard access and no major code upgrades |
| Tank removal and disposal | $250 | $500 | $1,000 | Higher when the tank is buried, contaminated, or difficult to reach |
| Basic labor | $400 | $750 | $1,200 | Usually includes setting the tank and connecting standard lines |
What a 138-Gallon Oil Tank Usually Costs Installed
A 138-gallon tank is a compact residential heating-oil storage option, but availability and exact dimensions vary by manufacturer. A new standard indoor tank often costs $500-$900; a coated steel or double-wall model may cost $800-$1,300. These are equipment prices, before delivery, installation, removal, or applicable tax.
For a straightforward replacement, homeowners commonly pay $1,500-$2,700 total. A new installation without an old tank to remove may fall near $1,200-$2,400, while difficult access, extensive piping changes, or a higher-cost region can push the project to $3,500 or more. Quotes should specify whether fuel transfer, old-tank disposal, fittings, and inspection are included.
Per gallon of rated capacity, the tank itself works out to roughly $4-$9, while a complete installed project may work out to about $11-$25 per gallon. That comparison is only a budgeting shortcut: installation has fixed labor and compliance costs, so a smaller tank does not usually reduce the total bill in direct proportion to capacity.
Assumptions: U.S. residential project, aboveground tank, standard access, ordinary labor rates, and no soil remediation or major heating-system work.
Budget about $2,400 for a standard installed replacement, then confirm removal and code-related charges in the written quote.
How Tank, Labor, and Removal Charges Build the Quote
Contractors may present one project total or separate line items. A useful estimate identifies equipment, work hours, delivery, removal, and any materials needed to connect the tank safely. The ranges below represent common U.S. planning figures, not a guaranteed local rate.
| Tank and job item | Materials | Labor | Equipment | Delivery/Disposal | Permits |
|---|---|---|---|---|---|
| Standard indoor replacement | $500-$900 | $400-$900 | $50-$200 | $250-$600 | $0-$250 |
| Coated or double-wall tank | $800-$1,300 | $500-$1,000 | $75-$250 | $250-$700 | $0-$300 |
| New installation with piping changes | $600-$1,400 | $600-$1,200 | $75-$300 | $100-$400 | $0-$350 |
Material charges may include the tank, legs or supports, gauge, vent and fill connections, filter, shutoff valve, and oil line fittings. Some parts can be reused if they are compatible and in sound condition, but a contractor may recommend replacement where age, corrosion, or current rules make reuse unsuitable.
Removal is a separate cost in many replacement quotes. An accessible empty tank may cost $250-$500 to disconnect and haul away. A tank with remaining oil, a narrow basement route, or evidence of a leak can require extra handling and raise removal charges to $1,000 or more. Ask whether residual oil transfer is included or billed separately.
Labor commonly accounts for several hundred dollars to over $1,000. A planning calculation is For example, 6-10 hours at $75-$125 per hour equals $450-$1,250 before materials and disposal. Minimum service charges may apply even when the physical installation is short.
The clearest quotes separate the tank price from installation, removal, delivery, and permit charges.
Which Tank Materials and Installation Conditions Raise the Price?
Tank construction is a major equipment choice. A basic single-wall steel tank may be the lowest-priced option where local rules and the installation location allow it. Factory-coated steel and double-wall tanks usually cost more, but may offer added corrosion protection or secondary containment. The specific design, approved use, and local requirements matter more than the label alone.
Capacity and footprint also affect the selection. A 138-gallon tank is much smaller than common 275-gallon residential models, but the smaller size does not guarantee a lower installation bill. Before ordering, verify the tank’s length, width, height, fill and vent locations, and required clearance against the available space. A tank that cannot pass through a basement doorway may require extra labor or a different model.
Site access changes crew time. A clear, level basement with a nearby entrance may fit a basic labor allowance. Stairs, tight turns, removal of stored items, or a tank location more than roughly 25-50 feet from the access point can add handling time. Outdoor installations may also require a stable pad, weather-rated components, and longer oil lines.
Line work and tank condition are additional quote drivers. Replacing a short, accessible oil line may add about $100-$400, while longer runs or buried lines can cost more and require different work. A visibly corroded tank, wet floor, persistent oil odor, or suspected leak can lead to inspection and cleanup that are not part of a routine replacement estimate.
Confirm the tank dimensions and approved installation location before paying for equipment.
How Northeast and Rural Labor Rates Change Tank Pricing
Regional pricing reflects labor rates, contractor availability, code requirements, delivery distance, and the prevalence of heating oil. In parts of the Northeast where oil heat is common, a basic replacement may often fall around $1,800-$3,000. In lower-cost areas with shorter travel and readily available equipment, a similar job may be about 5%-15% less.
Major metro areas can run roughly 10%-25% above a comparable rural quote because of higher labor, parking, access, and disposal expenses. Rural service calls can also cost more when a technician travels a long distance or the tank must be sourced specially. These percentages are broad comparisons, not regional price guarantees; a local written quote is more useful than a national average.
Ask contractors to identify the assumptions behind their pricing: number of workers, expected hours, distance or delivery fee, and whether the quoted tank is in stock. Compare quotes with the same capacity and construction type. A lower quote for a basic steel tank is not directly comparable to one for a double-wall model with removal and new piping included.
Compare local bids by matching tank specification and included work, not just the total at the bottom.
How Many Hours Do a 138-Gallon Tank Replacement Take?
A straightforward aboveground replacement commonly takes about 4-8 on-site hours for a small crew when access is clear and the old tank is empty. Disconnecting and removing an existing tank, transferring oil, or installing new piping can extend the job to 6-10 hours or longer. Time estimates depend on the layout and the contractor’s work sequence.
Labor rates for qualified heating-oil or plumbing contractors may run about $75-$125 per worker per hour, with variation by market and company. A two-person crew for 5 hours at $90 per worker-hour represents about $900 in labor before travel, materials, or disposal. Some companies charge a flat installation fee rather than showing hours.
Scheduling can affect price when a tank is leaking, heating service is interrupted, or emergency work is requested. After-hours or urgent service may add roughly $150-$500, or more in high-demand conditions. A routine replacement scheduled in advance generally gives the homeowner more time to compare bids and arrange oil handling.
Assumptions: One small crew, aboveground access, no structural work, and no cleanup of contaminated soil or building materials.
Request the estimated crew size and labor hours when a flat-rate quote is substantially higher than competing bids.
What Removal, Oil Transfer, and Code Work Can Add
Fuel remaining in the old tank needs a plan before work begins. Pumping oil into the new tank or a temporary approved container may cost about $100-$350, depending on volume and handling. The charge may be bundled with installation, so the estimate should state whether transfer is included and how unusable or contaminated fuel is handled.
Old-tank disposal commonly adds $250-$700 for a typical accessible aboveground tank. A tank that must be cut apart, carried through a narrow route, or treated as contaminated can exceed $1,000. If a contractor finds staining or a suspected release, stop-work, testing, cleanup, or environmental reporting may create separate charges that cannot be priced accurately before inspection.
Permits and inspections vary by city, county, and state. A straightforward permit may cost $0-$250, while extra inspections or required upgrades can bring the administrative and compliance portion to $300-$600. Requirements may cover location, clearance, supports, venting, fill piping, spill protection, or replacement of old lines. The installer should confirm which rules apply before work begins.
Delivery, new supports, and small accessories can add $100-$500 combined. A pad or platform, longer piping, a new filter, and protective fittings should appear as specific line items rather than an unexplained miscellaneous charge. If the project needs wall or floor repairs after removal, ask whether those repairs are included or handled by another trade.
Unplanned cleanup and code work are the biggest reasons a routine replacement estimate can rise after inspection.
Three Sample Quotes for Different 138-Gallon Tank Jobs
The examples below show how scope changes the total. Prices assume ordinary access and are illustrative planning ranges, not fixed market offers. A real quote should state the tank make and model, labor, disposal, and any local permit fee.
| Job scenario | Tank and unit price | Labor estimate | Other charges | Estimated total |
|---|---|---|---|---|
| Basic indoor replacement | Steel tank, $600-$850 | 5-7 hours, $450-$875 | Removal and fittings, $300-$650 | $1,500-$2,500 |
| Coated tank with new oil line | Coated tank, $850-$1,200 | 6-9 hours, $540-$1,125 | Line, delivery, and disposal, $450-$900 | $2,000-$3,300 |
| New tank in a difficult-access basement | Double-wall tank, $950-$1,300 | 8-12 hours, $720-$1,500 | Handling, supports, and inspection, $400-$900 | $2,300-$3,700 |
In the basic example, the old tank is accessible, compatible piping remains serviceable, and no permit or cleanup is required. In the second, a line replacement adds materials and work time. In the third, the higher total reflects a premium tank and extra handling; if access requires cutting or structural changes, the price may exceed the displayed range.
Use scenario estimates to check whether a bid’s scope is complete, rather than treating them as guaranteed prices.
How to Lower the Replacement Bill Without Cutting Safety
Compare at least two or three written estimates with the same tank capacity, material, and installation location. Ask each contractor to price removal, oil transfer, line replacement, delivery, permit handling, and taxes separately. This makes it easier to identify whether a low bid excludes necessary work or whether a high bid includes upgrades that are not required.
Keep the existing layout when it is safe and compliant. Moving the tank can require longer piping, a new support base, added fittings, and more labor. Before choosing that option, ask the installer whether the current location meets applicable clearance and access rules. Reusing sound components may reduce materials, but should not override the contractor’s safety assessment or local code.
Choose the tank specification based on the actual site and applicable requirements, not an assumed need for the most expensive model. Compare manufacturer coverage, corrosion protection, and construction details. A higher upfront tank price may be reasonable where the location or local rules call for added protection, but it is not automatically necessary for every installation.
Prepare the work area by clearing a path to the tank and arranging access before the crew arrives. This can reduce avoidable handling time, particularly in a basement. Schedule a non-emergency replacement before the old tank fails, if its condition allows; urgent service can narrow contractor choice and add a premium. Do not delay a suspected leak to save money, and do not attempt to disconnect or dispose of an oil tank without qualified help.
The most dependable savings come from comparing equivalent scopes and avoiding unneeded relocation or rush work.
