Residential Deck Leak Inspection Services

Professional Deck Leak Inspection in Vancouver & BC

Residential decks and balconies face constant exposure to BC's challenging climate. Whether you have a wood deck over living space, a composite deck system, or a residential balcony with waterproof coating, our inspection services identify leaks and water intrusion issues before they cause serious structural damage.

Types of Decks We Inspect

• Wood Decks Over Living Space: Traditional wood decks with waterproof membranes beneath protecting rooms below
• Composite Deck Systems: Modern composite materials with integrated drainage or membrane systems
• Residential Balconies: Attached balconies with traffic coatings or membrane waterproofing
• Roof Decks: Flat roof areas converted to usable deck space
• Covered Deck Structures: Decks with roofing that may still experience water intrusion

Common Deck Leak Sources

Our inspections consistently identify these common causes of residential deck leaks:

• Failed or aged waterproof coatings and membranes
• Improper flashing at ledger board connections
• Degraded caulking at posts, railings, and penetrations
• Inadequate slope causing water pooling
• Damaged or clogged drainage systems
• Rot and deterioration in wood deck boards allowing water through
• Failed door thresholds and wall transitions

Our Deck Inspection Process

A thorough deck leak inspection examines all components of the waterproofing system:

1. Surface Assessment: Evaluation of decking material condition, wear patterns, and visible damage
2. Drainage Review: Checking slope, drainage outlets, and water flow patterns
3. Connection Points: Inspection of all wall connections, ledger boards, and flashings
4. Penetration Check: Assessment of railings, posts, and other items that penetrate the waterproofing
5. Interior Inspection: Examination of areas below the deck for signs of water intrusion
6. Moisture Testing: Non-invasive moisture readings to detect hidden moisture

Waterproof Coating Assessment

Many residential decks rely on waterproof traffic coatings applied over plywood substrates. These coatings require regular maintenance and eventual replacement. Our inspections assess coating condition, identify areas of concern, and provide guidance on maintenance needs or re-coating requirements.

Structural Concerns

Long-term water intrusion can cause structural damage to deck framing, ledger boards, and supporting members. While we focus on leak detection and waterproofing assessment, we identify visible signs of structural concern that may warrant evaluation by a structural engineer.
