Service · A1 Chimney & Roofing
Chimney masonry repair is the brick-and-mortar work on the chimney: joints, units, and the way the stack is bonded. It is the right description when the damage is spread across the masonry, not limited to one brick or one joint.

The work
The work can include cutting out failed mortar, resetting loose brick, and rebuilding a short section that has separated. The crown and the flashing are checked because masonry repairs fail again if water still pours in from the top or from the roof joint.
A narrow joint repair is tuckpointing. A few broken units are brick repair. Masonry repair is the broader job when both are involved.
Why it matters
Open joints act like gutters. They pull water into the chimney, the water freezes, and the next season the gap is wider. That cycle is what turns a maintenance job into a rebuild.
Masonry repair stops the cycle on the part of the chimney that still has a sound core.
What to expect
The extent of the failed masonry is marked, the repair is explained, and the price is given before grinding or demolition starts.
