Free and low-cost plumbing and heating help in NYC: the programs that actually exist in 2026

By GW Mechanical Corp. Published October 21, 2026. About a 9 minute read.

People search for "free plumber NYC" every day, and the honest answer is that no city agency sends a plumber to fix your sink for free. What does exist is a set of government programs that pay for specific plumbing and heating work, forgive part of a water bill, or force a repair when a landlord will not make one. Some are worth thousands of dollars. Here is what is real as of October 2026, who qualifies, and how to use it. GW Mechanical Corp is a licensed NYC master plumber, not a city agency; we list these because customers ask, and because several of them require a licensed plumber's invoice to work.

1. Free lead water service line replacement (DEP)

The biggest one. The service line is the pipe from the city main under the street to your house, and the owner is responsible for it. Replacing a lead or galvanized steel line normally costs more than $10,000. The NYC Department of Environmental Protection is replacing them with copper at no cost to the homeowner in selected neighborhoods, funded by $96 million in state and federal money, with up to 7,000 lines planned out of roughly 121,000 known lead or galvanized lines citywide.

• Where it is running now: Bronx (Mount Eden, Fordham Heights, University Heights, Kingsbridge Heights, Belmont and Mount Hope completed; Melrose, Mott Haven, Concourse Village, Eastchester, Edenwald, Baychester, Williamsbridge, Norwood, Bedford Park, Pelham Gardens, Wakefield and Allerton underway) and Queens (Flushing, Murray Hill, Queensboro Hill, East Flushing).
• Coming in 2027: Soundview in the Bronx and Borough Park in Brooklyn.
• How it works: DEP mails eligible owners a letter with sign-up instructions. You do not apply cold; if you are in a target area and have not received a letter, call 311 and ask about the lead service line replacement program.
• Not in a target area? You can check whether your line is lead on DEP's service line map, and if it is, replacement is private work. We do it, with the DEP and DOT permits.

2. Leak forgiveness on your water bill (DEP)

If a leak you did not know about produced a huge water bill, DEP's Leak Forgiveness Program will in many cases recalculate the bill using your historical usage once the leak is repaired. It is not a refund of the repair; it is relief from the water that ran down the drain.

• Fix the leak first, and keep the licensed plumber's invoice describing the repair, plus photos.
• File a leak notice through your My DEP Account or 311, attach the invoice and receipts.
• Keep paying your normal historical amount while the bill is in dispute so interest does not accrue on the disputed part.
• Terms differ for leaks inside the house and leaks on the service line.

Every repair invoice we issue describes the leak, the location and the fix in the detail DEP asks for. If a bill spike is how you found the leak, say so when you call and we will document it that way.

3. The Home Water Assistance credit (DEP)

A $159 annual credit on the water bill for one-to-four-family homeowners who receive the HEAP regular heating benefit, the Senior Citizen Homeowners Exemption (SCHE), the Disabled Homeowners Exemption (DHE), or a qualifying veterans property tax benefit. It is automatic, shown on the bill as "NYC Home Water Assistance Credit." If you qualify and do not see it, call DEP customer service at 718-595-7000.

Related, for landlords: the Multifamily Water Assistance Program gives a 25 percent discount on water and sewer charges to qualifying buildings of five or more units housing low-income tenants, applied for through HPD.

4. HEAP: boiler repair or replacement up to $8,000 (New York State)

The Home Energy Assistance Program has a Heating Equipment Repair and Replacement benefit that pays the actual cost of repairing or replacing a furnace, boiler or other primary heating equipment, up to $4,000 for repairs and $8,000 for replacement. The 2026–2027 benefit opened October 1, 2026.

• Who qualifies: you own and live in the home, meet HEAP income and resource limits (for 2026–27, gross monthly income of $3,563 for one person, $4,659 for two, $5,756 for three, $6,852 for four, plus $710 per additional person), and complete an eligibility interview. Households already receiving SNAP, Temporary Assistance or SSI generally qualify on income.
• How to apply in NYC: through HRA, the city's HEAP local district; apply at access.nyc.gov or call the state HEAP hotline at 1-800-342-3009 to be directed. Bring proof of residency, recent pay stubs for every household member and photo ID.
• What it means in practice: HEAP pays an approved contractor directly for the work. If you think you qualify, apply before the boiler fails if you can; approval takes time and a cold house does not wait.

HEAP also pays a regular heating benefit toward fuel or gas bills (opening November 2, 2026, this season) and an emergency benefit when heat is off or fuel is critically low (opening January 4, 2027; NYC emergency line 718-557-1399).

5. EmPower+ and Weatherization: free insulation, heat pumps and heating repairs (NYSERDA)

For income-qualified households, NYSERDA's EmPower+ pays for air sealing, insulation and heat pumps. Households under 60 percent of median income (for a family of four in NYC, about $97,200) get the work free, up to $14,000 downstate plus up to $10,000 toward a heat pump; households between 60 and 80 percent pay half. The separate Weatherization Assistance Program, for households under 60 percent of median income, covers air sealing, insulation and heating system repairs through a local provider at no cost.

These are the programs to look at if you are considering a ductless mini split or a heat pump water heater instead of a like-for-like gas replacement. We will tell you which equipment qualifies before you decide.

6. HomeFix: low- or no-interest, potentially forgivable repair loans (HPD)

For owners of one-to-four-family homes who live there, with household income at or below 120 percent of Area Median Income (from $142,560 for one person up to $268,680 for eight), HPD's HomeFix program lends up to $100,000 for a one-unit home plus $30,000 per additional unit at 0 to 5 percent interest, with better terms and potential forgiveness for low-income and senior owners. Qualifying work includes heating systems, hot water heaters, plumbing, electrical and roofs. Condos and co-ops are not eligible. Apply through the Center for NYC Neighborhoods at sustainableneighborhoodsny.org or by calling the Homeowner Hub at 646-513-3470.

7. Tenants with no heat or hot water: 311 and HPD

If you rent and the landlord will not fix heat or hot water, the repair is not free to anyone, but it is free to you. Call 311 or file online. HPD inspects; no heat during heat season (October 1 to May 31) or no hot water at 120°F year-round is a Class C immediately hazardous violation with daily penalties for the owner. If the owner still does not act, HPD's Emergency Repair Program can send its own contractor to restore service and bill the owner for the work. Our heat season guide covers the rules in detail.

What is not free, so you are not surprised

• The Service Line Protection Program advertised with your water bill is insurance sold by a private company for a monthly fee. It can be worth it for an older line, but it is not a city benefit.
• "Free estimates" from plumbers, including ours, are free quotes, not free work. We give a written price after diagnosis and before any repair.
• Repairs inside your home after a city main break or street work are generally yours, though you can file a claim with the Comptroller's office if city work caused the damage.

How we fit in

None of these programs replaces a plumber; several require one. We provide the itemized invoices DEP needs for leak forgiveness, the written estimates HEAP and HomeFix ask for, and honest advice on whether a heat pump or a conventional boiler makes more sense for your house before you apply to a program that favors one or the other. Call 646-980-2411 or send a request, and tell us which program you are working with.
