Common Problems Solved

  • Mysterious water stains on drywall that appear only during heavy wind-driven rain.
  • Water entering window tracks or dripping from ceiling drywall inside units.
  • Failed waterproofing allowing moisture to seep through foundation walls.
  • Difficulty tracing water leaks back to their exact exterior entry point.

Benefits for Property Managers

  • Stops water damage before it leads to structural wood rot and toxic mold.
  • Pinpoints leaks accurately, avoiding the cost of guessing and random patching.
  • Prevents tenant complaints and insurance claim disputes.
  • Provides detailed reports for strata records and insurance adjusters.

Our Execution Process

Step 01

Consultation & Mapping

Interview building occupants to establish leak history and timing.

Step 02

Water Testing

Conduct calibrated water spray tests on the facade to recreate the leak.

Step 03

Thermal Imaging

Use infrared sensors to map damp insulation and tracking paths.

Step 04

Targeted Repair

Patch the envelope defect, replace sealant, or install new flashings.

Step 05

Retest

Respray the repaired area to guarantee the leak is fully resolved.

Diagnostic Leak Investigation & Building Envelope Water Ingress Repair

Water ingress is a frustrating and destructive issue for building owners and property managers. Water rarely travels in a straight line; it can enter a crack in the exterior stucco on the tenth floor, travel down inside the wall cavity, and show up on a suite ceiling on the eighth floor. Finding and repairing building envelope leaks requires experienced diagnostics, specialized testing equipment, and targeted repairs. Allweathercoating provides systematic leak investigation and repair services across Vancouver and the Lower Mainland.

Diagnostic Leak Tracing Methodologies

We do not guess where leaks originate. We use a systematic diagnostic process to trace water entry points:

  • Infrared Thermal Imaging: We use high-resolution thermal cameras to detect temperature differences. Damp insulation and concrete appear colder than dry materials, allowing us to trace the moisture path inside walls.
  • Calibrated Spray Testing: Following ASTM E1105 standards, we use spray racks to apply water to specific exterior joints and windows, simulating wind-driven rain to recreate and locate the leak.
  • Moisture Meters: We use non-destructive pinless moisture meters to check relative moisture levels in drywall and concrete without damaging interior finishes.

Targeted Repairs & Rainscreen Integration

Once the water entry point is identified, we design and execute a targeted repair to seal the envelope:

  • Sealant Replacements: Replacing cracked caulking around window frames and expansion joints.
  • Concrete & Stucco Patching: Repairing cracked stucco, routing concrete fissures, and applying breathable elastomeric coatings.
  • Flashing Restoration: Repairing or replacing damaged sill, deck, and roof flashings to ensure water is directed away from the wall cavity.

Reporting & Strata Documentation

For strata councils and insurance adjusters, clear documentation is vital. We provide detailed reports for every leak investigation, including photos of the testing setup, thermal scans, discovered defects, completed repairs, and final post-repair testing. This ensures you have a permanent record of the repair for strata files and insurance purposes.

Safety & Access Considerations

Performing leak repair & water ingress in vancouver requires meticulous planning under WorkSafeBC regulations. Our operations are governed by qualified SPRAT/IRATA technicians who conduct risk assessments, verify structural roof anchors, and set up secondary backup systems. We coordinate ground barricades to isolate work areas, keeping residents, shoppers, and pedestrians safe on the ground.

Frequently Asked Questions

Why are building envelope leaks so difficult to locate?

Water rarely travels in a straight line. It can enter a crack in the envelope on the 10th floor, run down inside the wall cavity, and only show up on a ceiling on the 8th floor. Our spray testing and thermal imaging locate the actual entry point.

Do you provide emergency leak call-outs?

We prioritize active water ingress investigations for our existing strata and commercial clients to help mitigate property damage as quickly as possible.

What is calibrated water spray testing?

It is a controlled test using spray racks and pressure sensors to simulate wind-driven rain on windows and cladding joints, recreating and isolating active leaks.

How does thermal imaging assist in locating water leaks?

Water evaporation cools building components. Thermal cameras detect these cold spots, allowing us to trace moisture pathways inside walls without opening drywall.

Do you repair interior drywall damaged by water ingress?

We focus on sealing the exterior envelope first to stop the leak. Once watertight, we can coordinate drywall repair and mold mitigation partners.

What are the main causes of water ingress in high-rises?

Common causes include cracked window caulking, failed structural expansion joints, torn balcony waterproofing membranes, and blocked drainage systems.

How long does a leak investigation project typically take?

Most envelope leak investigations take 1 to 2 days to trace the source, perform water testing, and document the findings.

Can a roof leak show up on lower floors?

Yes, water entering a roof deck can travel down vertical shafts, columns, or electrical conduits, leaking into suites multiple floors below.

Do you provide reports for strata insurance claims?

Yes, we provide detailed diagnostic reports with photos and thermal scans, which strata councils use to document damage for insurance claims.

How do you access the exterior facade to inspect and repair leaks?

Our certified SPRAT/IRATA technicians inspect and repair facade leaks using rope access, avoiding the setup costs and delays of scaffolding.
