Heritage Home Guide: Moss Treatment in Aurora
This is the working reference we hand to Aurora clients before we book a moss treatment appointment. Deeper freeze depths mean liner condensation and cap ice-loading. Below: what to expect, real numbers, and the questions worth asking before you book.

Which rules apply
Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most moss treatment work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.
Permit thresholds in Aurora
Aurora 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.
Common questions
Do you need a permit for moss treatment in Aurora?
Cleaning and inspection are permit-exempt in Aurora. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
Is moss treatment covered by home insurance in Aurora?
Sudden damage (storm, animal, appliance failure) is usually covered minus deductible. Gradual wear generally isn't. A written pro assessment before the claim call materially improves outcomes.
How much does moss treatment cost in Aurora?
Most Aurora jobs land between $349 and $558. Complex access or heritage masonry can reach $907. We quote fixed price after a free on-site scope.
How long does moss treatment take in Aurora?
3–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
Do you offer same-day moss treatment in Aurora?
Usually — call before 9am and we'll confirm a same-day arrival window inside Aurora for most standard scopes.
What warranty do you offer on moss treatment in Aurora?
Five-year written workmanship warranty on materials and labour, transferable to a new homeowner within that window. Manufacturer warranties on any installed products pass through separately.
Do you service condos and heritage homes in Aurora?
Yes. Condo boards in Aurora typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
