Window & Door Leak Detection
Find and fix window and door leaks before they cause expensive water damage to your property.
Comprehensive Window Testing
Windows and doors are common entry points for water infiltration, especially in BC's rainy climate. Our comprehensive testing identifies leaks at the earliest stage, preventing costly structural damage.
- Visual Inspection: Thorough examination of frames, seals, and flashing
- Thermal Imaging: Infrared cameras reveal hidden moisture
- Water Testing: ASTM-standard spray rack testing
- Moisture Mapping: Pin and pinless meters for accurate readings
What We Inspect
- Window frames and sashes
- Perimeter caulking and seals
- Head and sill flashing
- Weather stripping condition
- Exterior door thresholds
- Sliding and French doors
Common Window Leak Issues
Seal Failures
UV exposure and temperature cycling cause caulking and seals to crack, shrink, and separate from frames.
Flashing Problems
Missing, damaged, or improperly installed flashing allows water behind the window into wall cavities.
Weep Hole Blockage
Blocked drainage channels trap water in window tracks, leading to overflow and interior water damage.
Frequently Asked Questions
What causes windows to leak?
Window leaks are commonly caused by failed caulking and sealants, improper flashing installation, degraded weather stripping, frame settling or warping, and poor original installation. Age and sun exposure accelerate seal deterioration.
How do you test for window leaks?
We use a combination of visual inspection, infrared thermal imaging to find temperature anomalies, water spray testing following ASTM standards, and moisture meters to detect hidden water infiltration.
What are signs of a window leak?
Common signs include water stains around window frames, peeling paint or wallpaper, musty odors, visible mold or mildew, condensation between glass panes, and drafts or cold spots near windows.
Can window leaks cause structural damage?
Yes, untreated window leaks can cause significant damage including rotted framing, mold growth, insulation damage, and deterioration of interior finishes. Early detection prevents costly repairs.
