Service · A1 Chimney & Roofing
Chimney tuckpointing removes mortar that has cracked or fallen out and packs new mortar into the joints. The brick stays. The joint is what gets replaced.

The work
The failed mortar is ground out to a solid depth, the joint is cleaned, and new mortar is packed in and tooled to shed water. Smearing a thin coat over the old joint is not tuckpointing. That coat cracks off and the open joint is still there.
Tuckpointing is the right job when the brick units are sound and the joints are the failure. If the faces of the brick are popping off, the chimney also needs brick repair.
Why it matters
Mortar is the part of a chimney that weathers first. Open joints on the side that takes the weather pull in rain. The next freeze widens them. Repacking the joints stops that path.
The crown and flashing still matter. New joints under a cracked crown stay wet. Those are checked before the mortar work is called finished.
What to expect
The joints that need to be cut out are identified, the mortar work is explained, and the price is given before grinding starts.
