Moisture Source Inspection
(Root-Cause Assessment for Mold Issues)

Mold is usually not the real problem — it’s a sign of hidden moisture.

If mold keeps coming back, there is often a leak, condensation issue, or trapped humidity inside walls, ceilings, bathrooms, crawlspaces, or basements.

HM-PRO provides mold inspection and moisture detection in Redmond, Bellevue, Kirkland, and nearby Seattle areas. We help homeowners find where moisture is coming from, why it’s not drying out, and what needs to be fixed to stop the problem for good.

What this service helps you answer

What this inspection helps you understand
  • Where the moisture is coming from
  • (leak, plumbing, roof, window intrusion, or condensation)
  • Why the area is not drying out
  • (trapped humidity, poor airflow, missing vapor barrier)
  • Will mold come back after cleaning
  • (if the source remains — yes)
  • What should be repaired and in what order
  • (to prevent further damage and avoid unnecessary costs)

What we inspect in your home

We inspect the areas where moisture problems and mold most commonly develop in homes in Redmond, Bellevue, and Kirkland:
  • Indoor humidity levels, temperature, and moisture conditions
  • Signs of active and past water damage
  • Hidden moisture areas
  • (inside walls, behind cabinets, insulated corners)
  • Exterior water intrusion points
  • (windows, siding transitions, penetrations)
  • Roof and attic conditions
  • (staining, ventilation issues, exhaust problems)
  • Crawlspace and basement moisture
  • Plumbing systems
  • (bathrooms, kitchens, supply lines, drains)
  • HVAC and airflow issues
  • Bathroom fan performance and vent routing
  • We also identify likely hidden moisture sources based on real conditions — not assumptions.

Tools and methods we may use (non-destructive first)

  • Professional moisture meters
  • Thermal imaging to detect hidden moisture
  • Humidity and temperature readings
  • Targeted checks of common failure areas
If needed, we recommend small, controlled openings only after identifying the best location — so you don’t open walls blindly.

What you receive

  • Clear explanation of the root cause (what’s happening and why)
  • List of affected and at-risk areas
  • Step-by-step repair recommendations
Typical next steps may include:
  • fixing the moisture source
  • improving ventilation
  • removing damaged materials
  • rebuilding with proper moisture control
You also get clear guidance on what to do next.

What this service is (and isn’t)

This is a practical, contractor-focused inspection designed to solve the moisture problem at its source — not just clean mold.
Lab testing or air sampling is not always necessary, but can be arranged if needed for insurance, documentation, or specific health concerns.

  • Musty smell in the house
