What chimney contractors do
A chimney contractor inspects, cleans and repairs chimneys: the masonry, the crown and cap, the flashing where the chimney meets the roof, and the liners that vent fireplaces, boilers and furnaces.
- A leak around the chimney, or loose and cracked bricks.
- A fireplace or wood stove you want to use again.
- A new boiler, furnace or water heater that changes how the chimney vents.
Who licenses chimney contractors on Long Island
Suffolk County
- Because Suffolk's home improvement law reaches any repair to residential property and names masonry outright, a chimney repair business needs a county license unless exempt.
- Suffolk Consumer Affairs includes masonry when it spells out what home improvement covers.
Nassau County
- Nassau Consumer Affairs lists chimney and fireplace builders, repairs and cleaners among the home improvement work that needs a county license.
- Chimney cleaning is written into the home improvement definition in Nassau's Administrative Code.
Step by step: how to check a chimney contractor's license in Suffolk or Nassau.
Town by town
Each town page quotes that town's own rules for chimney work, with the date we read them.
| Town or city | County | What the town says |
|---|---|---|
| Town of Oyster Bay | Nassau County | Oyster Bay generally requires a permit for any fireplace or chimney, prefabricated ones included. |
| Town of Babylon | Suffolk County | Installing a wood-burning stove or fireplace in Babylon takes a building permit. |

| Town of Shelter Island | Suffolk County | On Shelter Island's 2022 schedule, fireplaces, wood stoves and chimneys cost $200.00 to permit. |
What it costs
Labor is a large part of any price. Long Island brickmasons and blockmasons earn a median $88,831 a year, from about $66,592 at entry level to $108,761 with experience. (New York State Department of Labor, wages updated to the first quarter of 2026.)
Chimney prices turn on the height and access, the condition of the masonry, liner work, and the flashing and crown. See the chimney repair cost guide.
What to ask before you hire
- Your county license number, so I can check it before I sign?
- A certificate of insurance sent to me by your insurer, not a photo?
- What did the inspection find, in writing, with photos?
- Does the liner suit what vents into it now, and the equipment I am adding?
- Is the flashing and the crown included in the repair?
- Does the job need a permit in my town?

Questions homeowners ask
Does chimney repair need a license on Long Island?
Chimney repair on a home is home improvement work, so the county home improvement license applies.
Why does a new boiler or furnace affect my chimney?
Newer equipment can vent differently than the old one, and the chimney or its liner may need changes. Ask the HVAC contractor and the chimney contractor to agree on the plan.
