Common Water Issue in BC
Drywall Bubbling or Blistering — Water Damage Evidence
Bubbling or blistering drywall in BC homes indicates water damage to the gypsum core. The paper facing separates from the gypsum when wet, creating a blister.
Possible Causes
- •Plumbing leak within wall causing water saturation
- •Exterior water entry through building envelope failure
- •Roof leak allowing water to run down inside wall cavity
- •Condensation within wall from thermal bridging or vapour barrier failure
- •Flooding or major water event that soaked the drywall
Recommended Steps
- 1Do not puncture blister — water may be trapped behind paper
- 2Check moisture content of affected area with moisture meter
- 3Identify water source by noting timing and conditions of moisture appearance
- 4Call professional leak detection to find source before any drywall repair
- 5Drywall with water damage must be removed and replaced — it cannot be dried
