The Cambridge rental market angle
Landlord waterproofing DIY on rental units in Cambridge 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 waterproofing is disproportionate to the cost savings.
Common questions
When's the best time of year for waterproofing in Cambridge?
Late September through mid-November with Cambridge averaging 109cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
How long does waterproofing take in Cambridge?
2–3 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
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.
Is waterproofing covered by home insurance in Cambridge?
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.
How much does waterproofing cost in Cambridge?
Most Cambridge jobs land between $415 and $664. Complex access or heritage masonry can reach $1,078. We quote fixed price after a free on-site scope.
Do you service condos and heritage homes in Cambridge?
Yes. Condo boards in Cambridge 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 waterproofing in Cambridge?
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.
Do you offer same-day waterproofing in Cambridge?
Usually — call before 9am and we'll confirm a same-day arrival window inside Cambridge for most standard scopes.
