Chase Cover you can actually trust
Builders install galvanized chase covers that rust through in 12–15 years, then dump water straight into the chase. We fabricate custom 24-gauge stainless covers with cross-breaks, drip edge, and correctly sized collars — a one-time replacement instead of a recurring one.
Every St. Catharines technician is WETT SITE-Basic certified at minimum, with two inspectors carrying full SITE-Comprehensive credentials.

Chase Cover in St. Catharines — common questions
What is a chase cover?+
The metal lid on a framed prefab chimney chase — the box-shaped structure clad in siding. It is not a chimney cap; the cap sits on the flue that passes through it.
How much does a stainless chase cover cost?+
Custom stainless covers run $690–$1,600 installed, depending on chase size and the number of flue penetrations.
Why is my chimney leaving rust stains on the siding?+
A pooling galvanized chase cover. Once it rusts through, water runs into the chase and rots the framing — replace it before the framing repair joins the bill.
