"We had a recurring leak in a 9th floor suite that two other contractors couldn't trace. Allweathercoating ran an ASTM spray test and found the actual entry point was an expansion joint failure three floors up. The repair was done the following week and the suite has been dry through two full rainy seasons."

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 matters. We provide written reports for every leak investigation, including photos of the testing setup, thermal scans, discovered defects, completed repairs, and final post-repair testing. This gives you a permanent record for strata files and insurance purposes.

How Much Does a Leak Investigation Cost for a Vancouver Strata Building?

Building envelope leak investigation costs depend on building height, scope of testing, and number of suspected entry points. What drives the scope — and therefore the cost — is whether the leak has a visible, accessible source or has been travelling laterally inside the wall assembly for some distance before appearing. Subsequent repair costs are quoted separately after the entry point is confirmed. Contact us to discuss what your specific situation requires; we can often advise on scope over the phone before booking a site visit.

DIY Leak Tracing vs. Professional Investigation: Why Guessing Costs More

Attempting to trace a building envelope leak without thermal imaging and calibrated spray testing almost always leads to incorrect diagnosis — and incorrect repairs. Because water enters at one location and travels laterally inside wall cavities before dripping at a completely different point, patching the visible wet spot rarely stops the leak. Professional diagnostic investigation using infrared thermal cameras and ASTM-standard spray rack testing identifies the actual water entry point with precision, so repairs are targeted and effective. The investigation cost is almost always less than what repeated contractor visits and interior restoration from a mis-diagnosed source will run.

Common Questions About Leak Repair & Water Ingress in Vancouver

Why are building envelope leaks so difficult to locate?

Building envelope leaks are difficult to locate because water does not travel in a straight line. Water can enter a hairline crack in the stucco on the 10th floor, travel laterally along a concrete slab, and drip from a ceiling on the 8th floor. Without calibrated spray testing and infrared thermal imaging, diagnosing the true entry point requires destructive investigation of walls and ceilings.

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.

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.

What is calibrated water spray testing?

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.
