The sloped concrete crown and metal cap on top of a brick chimney

Chimney Repair

Crowns, caps, tuckpointing, flashing, spalled brick, and fireboxes that no longer hold a fire.

Who it is for

Houses that smell damp at the fireplace, stacks with open joints, cracked crowns, or brick that is shedding its face after a few winters.

What done looks like

Water stays out of the top. Joints are full. Loose brick is replaced. The firebox is relined in firebrick when the liner is the problem, not the roof.

What to send

Daylight photos of all four sides if you can see them, the attic penetration, and a note on whether it smokes, leaks, or both.

On this line

  • The usual failure

    A cracked crown or a rusted cap lets water in at the top. Every freeze pries the courses apart on the way down. We start at the crown, not with a coat of paint.

  • Tuckpointing

    Mortar ground out and replaced. On an old chimney the new mortar has to be no harder than the brick. On a modern stack it has to survive the roof.

  • Flashing

    Step flashing and counterflashing at the roof. Masonry that is pointed and a roof that is still open at the cricket will leak. We say which trade owns the leak.

  • Firebox

    Firebrick relayed in refractory mortar, dampers that still move, smoke chambers that are not falling in. A surround and hearth that have cracked away from the opening get rebuilt with the hearth line.

Questions

Do you cap and crown?+

Yes. A sloped crown and a cap that covers the flue without choking it. The cap is metal. The crown is masonry. They are not the same piece.

My chimney leaks into the attic. Is that masonry?+

Sometimes. Sometimes it is flashing, sometimes both. Send the photos. If it is a roofing item we will tell you instead of selling a repoint.
