Is It a Damper Repair or a Fireplace Rebuild?

When we visit homes in Mahopac, smoke in the room is a reason to call, not a diagnosis. We inspect the fireplace and give you an estimate at the house. A damper that will not close can often be replaced on its own. A crumbled firebox needs a rebuild. A cracked flue needs relining.

  • ▶ A top-sealing damper when the throat damper no longer seals
  • ▶ Masonry repair when mortar has fallen out of the stack
  • ▶ Flashing repair where the chimney meets the roof
  • ▶ Waterproofing when the brick is taking on water
  • ▶ Oil and gas boiler flue cleaning when the heating flue is the problem, not the fireplace

What Lake Moisture Means for Mahopac Chimneys

Homes around Lake Mahopac, Lake Casse, and Kirk Lake range from older colonials and Victorians in the Red Mills area to newer builds off Route 6 and the Taconic State Parkway. Lake moisture and freeze-thaw winters stress crowns, mortar, and the flashing where the chimney meets the roof.

When we visit homes in Mahopac, smoke in the room is a reason to look, not a diagnosis. A damper that will not close can often be replaced on its own. A crumbled firebox needs a rebuild. A split crown can often be rebuilt without taking the firebox apart. We give you the estimate at the house. Learn more about Mahopac and Putnam County, or see our chimney and fireplace repairs.

Chimney and Fireplace Repair Questions

What Is the Difference Between a Damper Repair and a Fireplace Rebuild?

A damper that sticks or will not close can be replaced on its own, including a top-sealing damper.

A fireplace rebuild is for a firebox whose brick has failed. The inspection shows which one applies.

You get the estimate at the house after we look.

Can a Cracked Flue Be Patched, or Does It Need Relining?

If the liner is cracked or no longer intact, it needs relining.

If the liner is sound and only one part has failed, we can replace that part. We decide after we inspect the flue.

We bring a camera when we need to see inside the flue, including a Level II inspection or higher.

How Can I Tell if Water Is Coming From the Crown or the Flashing?

A cracked crown lets water in through the top of the chimney. Flashing lets water in where the chimney meets the roof. Stains inside the fireplace can come from either one.

We inspect both before we recommend a crown rebuild or flashing repair.

The estimate is given at the house after that look.
