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 liner install is disproportionate to the cost savings.
The St. Catharines rental market angle
Landlord liner install DIY on rental units in St. Catharines 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.

1 day is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.

Do you service condos and heritage homes in St. Catharines?

Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
