Flashing & Sealant Failure Detection Across BC
Pinpoint failed flashing and sealant joints that let water into the structure
About This Service
Flashing and sealants are the envelope details most likely to fail first — they age, crack, detach and oxidise at transitions, penetrations and joints where the cladding meets windows, parapets, decks and mechanical penetrations. A small failed flashing can direct volumes of water into a wall. We combine visual survey, water testing and thermal imaging to find every compromised detail so repairs are targeted and complete.

Frequently asked questions
What is the expected lifespan of building sealants?
Polyurethane sealants typically last 10–15 years; silicone can last 20+ years. UV exposure, movement and poor installation all shorten these lifespans significantly.
Can you spot a bad sealant job from a new building?
Yes — we regularly find installation defects on buildings just out of warranty. Improper joint design, wrong sealant product and missing backer rod all cause early failures.
Do you do the re-caulking as well?
We specialise in detection and diagnosis. Our report gives your caulking or envelope contractor the exact locations and specifications for correct repair.
