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

In this example, we begin by inspecting a chimney crown with a 2-inch overhang.

2: Bond Break

We discovered a bond break between the brick of the chimney and the concrete of the cap. Brick and concrete expand and contract at different rates; if no bond break is used, a horizontal crack will most likely develop, causing a leak.

To rectify this, we use a quality 50-year silicone to seal the brick to the concrete after the forms are removed.

3: Drip Edge

The drip edge shown here is meant to direct rainwater away from the chimney, preventing water from running down the sides and causing damage.

4: Expansion Gap

We maintain a 1/4-inch expansion gap between the clay flue and the concrete cap. This gap accommodates the different expansion rates of the materials, preventing cracks. We seal this gap with the same durable 50-year silicone for added protection.

5: Solid Masonry Interior

We perform internal chimney repairs using only solid masonry construction. Plywood and concrete boards simply won't cut it!

6: Pour Preparation

We finish preparing the area before pouring the concrete cap.

7: Reinforced Concrete Pour

During the pour, we incorporate wire reinforcement to prevent cracks, resulting in a robust and long-lasting cap.

8: Finishing Touches

Once the concrete cap is poured, we rub out the green concrete to eliminate imperfections (such as holes), achieving a smooth and aesthetically pleasing finish. We pay particular attention to the cap, as it is the starting point for most chimney issues.

Additionally, we replace any compromised material below the cap to prevent water penetration, which can freeze as well as crack the brick.
