Why Window Leaks Are a Major Concern in BC

British Columbia’s building stock spans everything from high-performance towers to aging wood-frame walk-ups. Across all regions, window leaks are among the most common and expensive building maintenance concerns—especially in areas with:

• High wind exposure (e.g., upper floors of high-rises)
• Heavy seasonal rainfall (coastal and mountain climates)
• Aging building envelopes
• Inadequate maintenance of caulking and sealants
• Poor original installation or flashing
• Window-to-wall interface failures in stucco or siding systems

When window systems fail, water doesn’t always appear at the point of entry. It may migrate through framing, insulation, drywall, or multiple floors before showing visible signs—often leading to repeated misdiagnosis.

At AnyLeak, we specialize in getting the true story behind window leaks, using science—not speculation—to isolate the source and define a clear path forward.

Types of Window Leak Issues We Diagnose

We provide window leak detection and inspections for all major property types and building materials. Common issues include:

1. Window Frame Seal Failures

• Failed gasket or perimeter seals
• Cracked vinyl or aluminum joints
• Improper or deteriorated caulking

2. Window-to-Wall Interface Leaks

• Flashing errors at the window head, sill, or jamb
• Lack of proper membrane detailing
• Water entering behind stucco, brick veneer, or siding

3. Condensation Misidentified as Leaks

• Thermal bridging leading to moisture buildup
• Insulated glazing unit (IGU) failure
• Poor interior humidity control mimicking leak symptoms

4. Multi-Floor Migration

• Window leaks on higher floors showing water signs in lower units
• Water bypassing windows and traveling through wall cavities
• Incorrect balcony or envelope detailing above windows

5. New Construction or Warranty Issues

• Leaks appearing during the 2-5-10 home warranty period
• Developer or builder disputes regarding workmanship
• Pre-possession inspection failures

Our assessments help confirm whether leaks are caused by poor maintenance, aging materials, or construction defects—critical for insurance, warranty, or legal purposes.

How Our Window Leak Detection Process Works

At AnyLeak, our approach is designed to be non-invasive, fast, and precise, using diagnostic tools and envelope science principles to uncover the real issue without damaging your property.

Step 1: Pre-Inspection Review

• We collect background details, leak history, and building information
• Request or review any prior repair attempts or consultant reports
• Confirm access arrangements for affected units or common areas

Step 2: On-Site Window and Envelope Inspection

• Visual review of interior and exterior window assemblies
• Identification of visible cracks, deterioration, or construction anomalies
• Noting of water stains, bubbling paint, or warping adjacent to windows

Step 3: Thermal Imaging

• Non-contact infrared scanning to identify moisture cold spots
• Reveals hidden water behind drywall or insulation
• Effective for comparing affected vs. unaffected areas

Step 4: Moisture Mapping

• Use of calibrated pin and pinless moisture meters
• Quantifies dampness levels in walls, window returns, and sills
• Helps establish whether leak is active or historic

Step 5: Controlled Spray Testing (If Required)

• Simulates wind-driven rain in a safe, controlled manner
• Helps confirm suspected leak entry points and test seal performance
• Follows AAMA or BC envelope testing standards as applicable

Step 6: Optional Borescope Inspection

• Fiber-optic camera used to view behind wall or window assemblies
• Confirms water tracking routes without demolition
• Especially useful for strata properties where drywall removal is restricted

Frequently Asked Questions

What is window leak detection?
Window leak detection involves identifying the precise location and cause of water infiltration around window assemblies, including glass units, frames, seals, and adjacent wall structures.

Why do windows leak?
Leaks are commonly caused by failed caulking, deteriorated sealants, poor flashing installation, broken seals, improper slope, or water buildup from clogged weep holes or building movement.

Do you service all areas of British Columbia?
Yes. We provide window leak inspection services throughout BC, including Vancouver, Burnaby, Surrey, Victoria, Kelowna, Nanaimo, Kamloops, Prince George, and more.

What types of buildings do you inspect for window leaks?
We inspect single-family homes, condos, high-rise buildings, townhomes, commercial spaces, schools, government buildings, and mixed-use properties.

How do you detect window leaks without causing damage?
We use non-invasive tools such as infrared thermography, moisture meters, and acoustic sensors to find moisture buildup behind walls, below sills, or within frames.

Can you detect if the leak is from the window or nearby components?
Yes. We can determine whether water is coming from the window unit itself or adjacent components like cladding, balconies, or roof overhangs.

Do you inspect both interior and exterior of the window?
Yes. We typically begin from the interior but can also assess exterior components when safe and accessible. For high-rise exteriors, we coordinate with access professionals if required.

Are sliding doors and glass patio doors included in your inspections?
Yes. We inspect all glazed systems, including sliding doors, French doors, and floor-to-ceiling window walls common in condos and commercial buildings.

Do you inspect windows in high-rise buildings?
Yes. We specialize in high-rise window leak detection and work extensively with property managers, strata corporations, and building engineers.

How do I know if my window is leaking?
Signs include visible water during rain, staining or bubbling paint around the frame, condensation between panes, soft drywall or wood near the window, or mold near sills and corners.

Can leaks appear without visible water?
Yes. Many leaks only become visible after causing hidden damage inside the wall or floor. We detect these early using moisture detection tools.

Can your inspection help resolve insurance or warranty claims?
Yes. Our professional reports are accepted by most insurers and builders and can support claims under the 2-5-10 home warranty system in BC.

How long does a window leak inspection take?
Most inspections take 1 to 2 hours per affected unit or area, depending on the complexity of the issue and accessibility of the window system.

Can you inspect multiple windows in a property or building?
Yes. We offer scalable services for inspecting several windows, floors, or building facades, including for whole-building assessments.

Are your inspections truly non-invasive?
Yes. We use non-destructive tools and do not cut into walls or remove trim unless specifically requested or necessary with client approval.

Do you assess flashing and waterproofing membranes?
Yes. We check for missing or failed flashing, incorrect slopes, and compromised membranes around window openings.

Do you detect wind-driven rain penetration?
Yes. We inspect for pressure-related leaks that may only occur under high wind or storm conditions—common in BC’s coastal areas.

Do you inspect newly installed windows?
Yes. We inspect post-installation to verify proper sealing and performance, and we often find installation deficiencies in new builds.

Can you assess historic or custom windows?
Yes. We inspect wood-frame and heritage window systems with care, offering sensitive leak assessments for older properties.

Do you help identify building envelope failures that affect window performance?
Yes. We examine the interface between windows and surrounding walls to determine whether the problem lies with the window or envelope.

Can you help strata councils understand unit vs. common property responsibility?
Yes. Our findings clarify whether a leak originates from a common element or private unit, helping resolve repair responsibility and disputes.

Can you verify if previous repairs have worked?
Yes. We perform follow-up inspections after repairs to ensure the leak is fully resolved and no new moisture is present.

Do you inspect curtain wall and window wall systems?
Yes. We are trained in diagnosing water ingress in both traditional and modern multi-story glazing systems.

Do you provide recommendations after inspection?
Yes. Our reports include not just findings but suggested next steps, including maintenance, repair, or further specialist evaluation if needed.

Can you inspect commercial storefront windows and glass walls?
Yes. We assess window performance in retail, hospitality, and institutional buildings where water ingress can affect business operations.

Do you test windows for energy efficiency or air leakage?
While our primary focus is water intrusion, our infrared imaging may reveal energy inefficiencies or air leaks during the inspection.

Are your technicians licensed and insured?
Yes. Our inspectors are fully trained, licensed, and insured for residential, commercial, and government projects.

How much does a window leak inspection cost?
Costs vary by location, property size, and the number of affected windows. Contact us for a customized quote.

Do you inspect condo windows as part of building-wide leak issues?
Yes. We work closely with strata corporations to assess and document window conditions across multiple units and elevations.

Can you inspect during rainy weather?
Yes. Rain can actually help us detect active leaks more effectively using our thermal and acoustic tools.

How quickly can you respond to a leak concern?
We offer flexible scheduling and priority response across BC for active leaks or time-sensitive inspections.
