Chimney Cap & Damper Installation in Markham
Stainless caps, custom multi-flue covers and top-sealing dampers fitted to Markham chimneys to keep out rain, snow and wildlife. 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.
