After years of inspections and diagnostics across Newfoundland, patterns emerge. These are the five most common building problems we see — and the earliest signs of each.
1. Wind-driven rain intrusion
Failing sealants and flashing on the windward face — usually east and southeast — combined with pressure differentials that pull water horizontally into walls.
2. Ice damming
Inadequate attic insulation or ventilation lets heat melt snow, which then refreezes at the eaves and forces water back under shingles.
3. Basement moisture
Grading, drainage, and foundation waterproofing failures — often layered on top of each other in older properties.
4. Envelope condensation
Tighter modern homes with under-designed ventilation trap moisture that then condenses on cold surfaces inside walls.
5. Deferred exterior maintenance
Paint, caulking, and cladding failures that cascade quickly into moisture problems if left unattended.
Frequently asked questions
- Can I identify these problems myself?
- Sometimes — but signs are often subtle. An hour with a thermal camera reveals things a walkthrough never will.
- Which of these is most expensive to fix late?
- Envelope condensation, because the damage is inside the wall assembly and often widespread by the time it's found.
