Chimney Repair & Masonry in Markham
Repointing, crown rebuilds, cap replacement and leak tracing by red-seal masons working across Markham. Most Markham homes run factory-built metal fireboxes with sealed direct-vent gas inserts. Those need annual burner cleaning, glass and gasket checks and a combustion test rather than a traditional brush sweep — and the long dryer vent runs common in Cornell and Box Grove clog faster than average.
