Mississauga building services generally require a permit for any structural masonry, liner replacement, or new appliance install. Cleaning, cap replacement, and cosmetic work are permit-exempt. Turnaround for over-the-counter permits is usually 5–10 business days.
Certifications that carry weight
WETT SITE-Comprehensive, CSIA CCP or CCS, and WSIB clearance are the three signals adjusters and buyers accept without pushback. HRAI membership adds credibility on venting work.
Which rules apply
Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most roof repair work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.
Common questions
What if it rains or snows on the booking day?

Late September through mid-November with Mississauga averaging 95cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
