Crown cracks leading to water leaks
Why it happens here
Concrete crowns expand and contract with Martinsville's freeze-thaw cycles. Hairline cracks open up, water gets in, and the next freeze widens them. Most crowns on chimneys over 25 years old have some cracking.
Our approach
We rebuild crowns with a flexible crown mix designed to handle movement, then seal them with ChimneySaver waterproofing. This stops the crack cycle instead of just patching it. Most crown repairs in Martinsville last 15 to 20 years.
