The Ajax rental market angle

Landlord liner install DIY on rental units in Ajax 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.

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.

Common questions

Do you service condos and heritage homes in Ajax?

Yes. Condo boards in Ajax typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.

What warranty do you offer on liner install in Ajax?

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 much does liner install cost in Ajax?

Most Ajax jobs land between $1,610 and $2,575. Complex access or heritage masonry can reach $4,185. We quote fixed price after a free on-site scope.

When's the best time of year for liner install in Ajax?

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

Is liner install covered by home insurance in Ajax?

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.

Do you need a permit for liner install in Ajax?

Cleaning and inspection are permit-exempt in Ajax. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.

Do you offer same-day liner install in Ajax?

Usually — call before 9am and we'll confirm a same-day arrival window inside Ajax for most standard scopes.

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.
