Mold Removal & Remediation in Redmond, WA
Containment, HEPA filtration, and antimicrobial treatment eliminate mold colonies at the source and prevent cross-contamination throughout the property. Mold remediation removes affected porous materials and corrects the moisture source that allowed growth. The work is done under containment with HEPA filtration so spores are not carried into unaffected rooms, and the area is cleared only once the underlying moisture problem has been resolved.
Quoted on site by the contractor who visits
Remediation is the step after the assessment, not before it. A local pro establishes how far the growth extends and what is feeding it, because removing what is visible while the moisture source is still running puts the same colony back in the same wall. Texas and several other states also set a square-footage point above which the work has to be done by a licensed remediator — the service note below covers where that line falls in this city.

Category 3 black-water losses are handled with full PPE, biohazard disposal, and professional disinfection to restore safe conditions.
Frequently asked questions
There are old field drains under this subdivision. Do they still run?
They do, and not where anyone expects. Farm laterals still move water through the alluvium beneath houses that replaced the fields, so water arrives along lines no current plan shows. The farm drainage outlived the farm.
The house is on Education Hill. Is the river still in play?
Not as flood. The hill job is till shedding December onto the next roof down. That water lands in the valley, so a downhill crawl can take a hill storm with the Sammamish quiet. The two jobs meet at the break in slope. Willows and Overlake take the hill's December; the valley floor then holds it on peat, which is why both jobs show up in one city.
The house has settled and the crawl is wetter than it used to be. Related?
Same cause. Valley peat compresses under a 1990s pad, and as the ground gives, December rain perches where it did not before. The settlement and the water are one process, not two separate problems.
