Boiler Removal Cost: What You'll Actually Pay [2026]

The type and age of your boiler determines the removal cost more than any other factor. Modern gas boilers are relatively compact and easy to remove. Old cast iron boilers can weigh over 1,000 pounds and require disassembly in place.

Gas boilers (modern) weigh 100 to 300 pounds and are the simplest to remove. HVAC contractors typically charge $200 to $500 for removal and disposal when bundled with a new installation, according to Runwise and Lehigh HVAC.

Cast iron sectional boilers are the most challenging. These units weigh 300 to 1,000+ pounds depending on the number of sections. They must be disassembled section by section using a hammer and chisel to separate the push nipples connecting each cast iron section. CommTank estimates $500 to $1,000 for a residential cast iron boiler removal.

Oil boilers add complexity because the oil tank must also be addressed. An above-ground oil tank removal adds $500 to $1,500 to the project. Underground oil tanks cost $1,500 to $3,000+ to remove due to soil testing and environmental regulations.

Steam boilers are typically cast iron and connected to a network of radiators throughout the house. Removing just the boiler is straightforward, but if you're decommissioning the entire steam system, expect to pay for radiator removal and pipe capping throughout the home.

• •Basement access — A walkout basement makes removal straightforward. A cellar with narrow stairs, tight corners, or a bulkhead hatch may require disassembly before the boiler can exit. Junk haulers on Facebook report charging $1,200 for basement boiler demolition versus $250 when the unit is already outside.

• •Boiler weight and construction — A 150-pound wall-mounted gas boiler lifts off in minutes. A 700-pound cast iron sectional boiler takes hours to hammer apart section by section. Each cast iron section typically weighs 75 to 150 pounds.

• •Asbestos — Boilers installed before 1980 may have asbestos insulation on pipes, the boiler jacket, or the flue connector. Professional asbestos testing costs $25 to $75 per sample. If asbestos is found, licensed abatement adds $1,500 to $3,000 before the boiler can be removed. Never disturb suspected asbestos insulation yourself.

• •Connected systems — Removing a boiler connected to radiators, baseboard heaters, or radiant floor heating means draining the entire hydronic system first. If you're keeping any part of the system, a plumber must cap all disconnected lines ($50 to $100 per connection).

• •Oil tank situation — If your oil boiler has an underground storage tank, tank removal and soil remediation can cost more than the boiler removal itself.

Cast iron boilers have decent scrap value. A 300 to 600 pound cast iron boiler is worth roughly $20 to $45 in scrap metal — possibly $60 if you separate the copper fittings and piping.

More importantly, many scrap metal haulers and scrappers will remove a cast iron boiler from your basement for free because the metal is valuable enough to justify the labor. Reddit users in r/AskChicago and r/Plumbing report that scrappers took their old boilers at no charge during renovations.

To find free boiler removal, try:

• •Post in the "free" section of Craigslist with a photo and weight estimate
• •Call local scrap yards and ask if they do residential pickups
• •Ask your HVAC contractor if they keep the scrap value in exchange for free removal
• •Check Facebook Marketplace "free stuff" groups in your area

This approach works best for cast iron boilers since they have the highest weight-to-value ratio. Modern gas boilers with mostly sheet steel have lower scrap value and may not attract free pickup offers.

• •Bundle with replacement — HVAC contractors almost always include old boiler removal in the installation price. Removal adds just $200 to $500 to a $3,500 to $8,500 replacement job. If removal isn't listed in your quote, negotiate it in before signing.

• •Call scrappers for free removal — Cast iron boilers are heavy enough that scrap haulers will often remove them for free. Post on Craigslist or call local scrap yards.

• •DIY disassembly + curbside pickup — If you're handy, you can disassemble a cast iron sectional boiler section by section (each 75 to 150 pounds) and move the pieces to the curb for Dropcurb pickup at $79. Have a licensed plumber disconnect gas and water lines first ($100 to $200).

• •Time it with other metal removal — If you're also removing radiators, pipes, or other metal items, bundle everything for one scrap hauler trip. The combined weight makes free pickup more likely.

• •Check municipal programs — Some cities have special heavy item pickup or will direct you to free disposal facilities for large appliances.
