Chimney & Fireplace Repairs

On Top Service offers a variety of chimney repairs to keep your fireplace and chimney operating at its best.


Chimney Restoration and Reconstruction

Whether your chimney is in need of minor repairs or complete reconstruction, On Top Service technicians and masons are trained to help you determine the appropriate course of action. No job is too big or too small, and you’ll appreciate our professional craftsmanship and care for your home. We have a full time staff of masons that specialize in diagnosing and repairing any type of masonry problem.

Firebox Repointing and Rebuilding

The firebox of your fireplace takes a lot of heat and abuse! If your firebox has any loose bricks or mortar joint erosion of more than 1/2 inch it may be time for a repair.

Mortar Crown Repair

The mortar crown is the concrete-like surface at the top of your chimney. Its job is to shed water away from the flue and keep water from entering the chimney chase. Cracks or missing pieces in your mortar crown can lead to extensive water damage in your chimney. Mortar crowns can be repaired with traditional masonry products or a specialized waterproof product called CrownCoat.

Damper Repair

If your fireplace does not have a damper, you are pumping money up your chimney! A damper stops heat from escaping up your chimney when the fireplace is not in use. We offer top sealing dampers to conserve your home’s heat and help keep your money in your wallet.
