DIY vs Pro: Vent Repair / Reroute in Markham

Duration

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.
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 vent repair / reroute is disproportionate to the cost savings.
The Markham rental market angle
Landlord vent repair / reroute DIY on rental units in Markham voids most policies and shifts full liability to the owner under RTA §20. Not worth it.
Common questions
Do you need a permit for vent repair / reroute in Markham?
Cleaning and inspection are permit-exempt in Markham. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
How much does vent repair / reroute cost in Markham?
Most Markham jobs land between $342 and $547. Complex access or heritage masonry can reach $889. We quote fixed price after a free on-site scope.
How long does vent repair / reroute take in Markham?
2–4 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 vent repair / reroute in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
When's the best time of year for vent repair / reroute in Markham?
Late September through mid-November with Markham averaging 148cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
Is vent repair / reroute covered by home insurance in Markham?
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.
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.
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.
