Our Chimney Repair Process
At D. Thomas Masonry, we take pride in our approach to chimney repair, focusing on durability and longevity that surpasses standard practice. Below is an example process of a previous project:
1: Chimney Crown Inspection
We start by inspecting the chimney crown, which features an overhang to shed water away from the structure.

2: Bond Break
Brick and concrete expand at different rates - without a bond break, horizontal cracks and leaks are nearly inevitable.

3. Drip Edge
The drip edge directs rainwater away from the chimney, keeping it from running down the sides and causing damage.

4: Expansion Gap
A 1/4-inch gap between the clay flue and concrete cap absorbs movement between materials, preventing cracks. We seal it with 50-year silicone.

5: Solid Masonry Interior
Internal repairs use solid masonry only. Plywood and concrete board don't belong in a chimney.

6: Pour Preparation
We clean and level the surface and set the forms before the concrete cap goes in.

7: Reinforced Concrete Pour
Wire reinforcement goes in during the pour, producing a cap that resists cracking for the long haul.

8: Finishing Touches
We rub out the green concrete to eliminate holes and imperfections for a clean finish. Any compromised material below the cap gets replaced.
