Chimney Liner Installation & Relining in Monsey & 30 miles around

What this service actually is

The liner is the one component standing between a 1,100°F flue fire and the wood framing of your house. Older clay tile liners crack from heat shock and settling; many homes built before the 1950s have no liner at all. We install lifetime-warrantied stainless steel liners sized to your exact appliance.

What you get

• UL-1777 listed stainless steel liners with lifetime warranty options
• Correctly sized to the appliance — oversized flues cause draft and condensation problems
• Insulated liner wrap for better draft and less creosote
• Required for most wood stove, insert and high-efficiency furnace installs
• Usually a single-day job with no interior demolition

How we do it

1. Camera survey and sizing

We scan the existing flue, measure the appliance outlet and calculate the correct liner diameter. Guessing here is how people end up with a smoky house.

2. Install and insulate

The stainless liner is run from the appliance to the top of the flue, insulated where code requires it, and locked to a top plate and cap.

3. Seal, connect and test

We seal the base, connect the appliance, run a draft test and leave you with the warranty paperwork and a system that passes inspection.

Signs you need chimney relining

If any of these sound familiar, it is worth a call. There is no charge to ask.

• Pieces of clay tile falling into the firebox or landing on the smoke shelf
• A camera inspection showed cracked, gapped or missing tiles
• You are installing a wood stove, insert or new high-efficiency furnace
• You have had a chimney fire — the heat almost always damages the liner
• The home is pre-1950 and the flue was never lined

What it costs

Chimney Liner Installation & Relining typically runs $2,200 – $4,800 for a standard single-family home in our service area, and takes about 1 day. The variables that move that number are roof access, flue height, how many flues share the stack, and condition.

“Fourth year in a row using them. Same tech, on time, in and out in an hour, and he always shows me the camera footage. That is worth a lot.”

Why homeowners pick Hero

We are a family company working out of Monsey, not a national franchise routing your call to a dispatcher three states away. That means the person who quotes your job is on the roof doing it, the price does not change halfway through, and if something is not right afterward we are twenty minutes away.

Every visit includes photo documentation. Every recommendation comes with an explanation of what happens if you wait, so you can make the call on your own timeline instead of ours.
