Chimney Liner Installation in the Pittsburgh Area

The liner is the inner channel of the flue that contains the heat, smoke and gases of a fire and carries them safely out. Liner installation fits a new liner — commonly stainless steel — sized correctly to the fireplace or appliance it serves.

What chimney liner installation involves

The liner is the inner channel of the flue that contains the heat, smoke and gases of a fire and carries them safely out. Liner installation fits a new liner — commonly stainless steel — sized correctly to the fireplace or appliance it serves.

Why homeowners need it

The liner is the safety barrier between the fire and the rest of your house. A missing, undersized or damaged liner lets heat reach framing and lets combustion gases seep into the masonry. Installing a correct liner is fundamental to a chimney that's safe to use.

Common problems it addresses

  • No liner, or an unsafe original liner
  • A flue sized wrong for the current appliance
  • Cracked clay tiles that can't contain heat or gas
  • A liner change needed after a new stove or insert

Warning signs to watch for

  • You've added or changed a heating appliance
  • An inspection found liner cracks or gaps
  • The chimney serves an appliance with no proper liner
  • Draft or performance problems tied to flue size

How we approach the work

Size the liner

We match the liner to the appliance and flue for correct draft and safety.

Prepare the flue

We clear the flue and address anything that would interfere with the liner.

Install

We run the new liner and connect it properly at the top and bottom.

Insulate and finish

We insulate where needed and finish with the correct cap and top connection.

Materials and equipment

  • Stainless steel liner sized to the appliance
  • Liner insulation where required
  • Top plate, connector and cap

What this means for Pittsburgh-area homes

Many older Pittsburgh homes have clay-tile flues that are cracked, offset or simply the wrong size for a modern insert or furnace. A stainless liner is the standard fix — it restores a safe, correctly sized flue inside the existing masonry chimney.

Frequently asked questions

Why would I need a liner installed?

Common reasons: the chimney never had a proper liner, the clay tiles have cracked, or you've added a stove, insert or furnace that needs a different flue size. A correct liner makes the chimney safe for what it now vents.

What size liner do I need?

It depends on the appliance — an undersized or oversized flue both cause problems. We size the liner to the specific fireplace, stove or appliance it serves.
