Leak detection & moisture mapping

We begin with non-invasive leak detection and moisture mapping to locate damp materials and narrow down the likely source before opening walls. Moisture readings and thermal imaging help guide the investigation; concealed leaks may still require controlled access to confirm their source.

Mold assessment & a clear plan

Based on the moisture findings and visible conditions, we determine whether a mold assessment is needed. When it is, we use the mold assessment report and remediation protocol to plan containment, define the work area, and coordinate a start date for invasive leak detection together with mold remediation.

Containment & vapor barriers

Temporary polyethylene barriers seal off the work area and help limit the spread of dust, debris, and mold particles into surrounding rooms. These containment barriers create a controlled workspace before materials are disturbed. They serve a different purpose from a permanent vapor barrier installed within a building assembly to manage moisture movement.

Negative air & HEPA filtration

Negative air keeps the contained work area at a lower air pressure than adjoining spaces, drawing air inward rather than allowing contaminated air to escape. A properly configured HEPA-filtered exhaust system helps capture airborne particles and maintain this airflow during controlled work. Air filtration alone does not establish negative pressure.

Invasive leak detection & mold remediation

Once the required assessment, plan, and protective controls are in place, we coordinate targeted wall openings to trace concealed leaks and access affected materials. Where mold remediation is needed, the work follows the remediation protocol so investigation and removal are planned together, with the leak source addressed as part of the overall project.

Water damage drying & moisture checks

Drying equipment and moisture checks help track the condition of affected materials as the project progresses. The drying approach is coordinated with leak correction and any required remediation, with progress reviewed before the next stage of restoration.
