At Gralak Masonry, we also provide repairs or replacements of the following chimney structures.
The chimney crown is typically made of concrete. It’s the structure that overhangs the top of the chimney itself. It is designed to shed water away from your chimney.
Because it’s at the chimney’s top, it must especially endure the Chicago weather extremes. So, it’s important to inspect its mortar joints annually and tuckpoint them as needed.
We also inspect the integrity of the concrete and repair or replace it as needed.
Furthermore, brick chimneys need chimney caps (called chimney rain caps, flue caps, chimney covers, and animal guards.) This structure sits atop your chimney crown. We install the top metal cover on the flue if necessary. We will also replace the caulking around the chimney cap.
Chimneys require metal flashing where they meet the roof. If not caulked (or re-caulked) properly, these can allow water intrusion. When flashing rusts, a qualified roofing specialist needs to replace it. However, Gralak Masonry does replace caulk around the roof flashing.
