A single moldy spot, a closet, or under a sink. The crew seals it off, removes it, and treats the surface.
A bathroom, kitchen, or bedroom with mold on a wall or ceiling, plus the moisture source fixed.
Larger areas that need more containment and drying. Common here after spring rain or a slow leak.

On the job
Mold remediation work in Nine Mile Falls homes
Why crawl spaces in Nine Mile Falls develop mold
Dirt crawl spaces absorb moisture directly from the soil, releasing water vapor into the framing above. Limited airflow creates a consistent environment for mold growth.
Seasonal rain in Spokane County increases soil moisture around foundations, pushing more vapor into unsealed crawl spaces.
For independent guidance on mold, moisture, and safe cleanup, see EPA: A Brief Guide to Mold, Moisture and Your Home and CDPHE: Washington Department of Public Health & Environment.
- Ground moisture wicking up through an exposed dirt floor
- Spring spring rain saturating soil right against the foundation
- Dead air holding humidity against joists and subfloor
- Framing sitting inches above damp, uncovered soil
The function of encapsulation
Encapsulation seals the space with a vapor barrier, preventing ground moisture from reaching the air and wood framing.
This approach addresses the moisture source, offering a more lasting solution than cleaning alone.
- Vapor barrier run across the floor and up the foundation walls
- Seams overlapped and taped into a continuous moisture barrier
- Existing growth removed and framing treated before sealing
- A drier space for ductwork, piping and anything stored there
Integration with radon mitigation
Many homes in Nine Mile Falls have radon mitigation systems. Encapsulation is designed to work around existing piping and suction points.
The vapor barrier is installed to accommodate the radon system, ensuring it continues to operate effectively.
- Vapor barrier detailed around existing radon vent piping
- Radon fan and draw checked after the barrier is complete
- Existing mitigation equipment left sealed and undisturbed
Determining if encapsulation is needed
Recurring mold on joists, musty odors in living areas, or visible dampness indicate a need for remediation and sealing the space.

Good to know
Crawl Space Encapsulation in Nine Mile Falls, WA: common questions
Is mold removed before encapsulation?
Yes. Active mold is remediated and framing is treated to the IICRC S520 standard before the barrier is installed.
How long does the process take?
Duration varies based on square footage and remediation needs, but most projects are completed within days.
Is my crawl space a candidate?
Crawl spaces with dirt floors, recurring moisture, musty odors, or visible mold are typical candidates. An inspection can confirm.
Does encapsulation affect radon systems?
No. The barrier is installed to work around existing radon vent piping and suction points.
Does encapsulation prevent mold return?
It stops the ground moisture that causes most recurring growth. Separate issues like plumbing leaks require additional fixes.
