Condo Owner Guide: Waterproofing Rules in Newmarket

Here's how Newmarket homeowners actually approach waterproofing in 2026, based on what our field crews see every week. Deeper freeze depths mean liner condensation and cap ice-loading. Below: what to expect, real numbers, and the questions worth asking before you book.

Quick answer

Waterproofing in Newmarket falls under Ontario Building Code §9.22 and CSA B365. Cleaning is permit-exempt; structural or liner work is not.

Typical

$399–$638

Duration

2–3 hrs

Freeze-thaw

70/yr

Which rules apply

Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most waterproofing work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.

Permit thresholds in Newmarket

Newmarket 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

Is waterproofing covered by home insurance in Newmarket?

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 service condos and heritage homes in Newmarket?

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

When's the best time of year for waterproofing in Newmarket?

Late September through mid-November with Newmarket averaging 154cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.

How long does waterproofing take in Newmarket?

2–3 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.

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.

Do you offer same-day waterproofing in Newmarket?

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

Do you need a permit for waterproofing in Newmarket?

Cleaning and inspection are permit-exempt in Newmarket. 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.
