What needs a pro
Anything requiring roof access, working chemicals or sealants, disturbing masonry, disassembling the appliance, or interpreting a scan. The insurance and liability exposure on DIY moss treatment is disproportionate to the cost savings.
The Erin rental market angle
Landlord moss treatment DIY on rental units in Erin voids most policies and shifts full liability to the owner under RTA §20. Not worth it.
What you can safely DIY
Visual inspection with a flashlight, exterior debris clearing from the cap area (from a stable ladder, not the roof), and photo-documentation of concerns. That's the safe list.
Common questions
Do you service condos and heritage homes in Erin?
Yes. Condo boards in Erin typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
Do you need a permit for moss treatment in Erin?
Cleaning and inspection are permit-exempt in Erin. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Are you WETT and WSIB certified?
Yes — WETT SITE-Comprehensive #C-46082, CSIA #12408, and active WSIB #7248194. Certificates emailed on request before the job.
Is moss treatment covered by home insurance in Erin?
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.
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.

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.
How long does moss treatment take in Erin?
3–4 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
