Containment & negative air
Plastic barriers with zipper doors and negative air machines keep air flowing into the work area, never out of it.

Mold in a bathroom, a crawl space or the garage? Our Tukwila crew finds the moisture, contains it and removes it.

Mold Remediation, Seattle
Seattle's long, damp winters mean mold is a regular call for us. It grows in crawl spaces with no vapor barrier, bathrooms without a working fan, closets on cold exterior walls and around single-pane windows that sweat every morning. A hidden leak makes it worse fast.
We find the moisture source with meters and thermal imaging, seal the area under negative air, remove moldy materials, HEPA clean and treat the framing and test again to confirm the result. Then we fix what feeds it, from a leaking pipe to a missing bathroom fan.
Scrubbing or spraying mold can send spores through the house. Book an inspection and we will plan the removal properly.

Seattle mold
Humidity alone rarely does it. Mold here usually has a cold surface or a hidden leak behind it.
Dirt crawl spaces without a good vapor barrier stay damp all winter. A leaking pipe underneath, like one we found on a Seattle crawl space job, speeds things up.
Single-pane windows, uninsulated exterior walls and garage walls in older homes collect condensation. Mold grows on the sills, the drywall and the backs of closets.
Older bathrooms often lack an exhaust fan or have one that does not vent outside. Steam soaks the ceiling every day until mold shows up.

Mold grows where moisture sits, and that is usually inside walls, ceilings and crawl spaces. This video shows how our crews find it and remove it safely.

Killing the mold you can see doesn't stop the mold you can't. Here's how we take it out for good.
Moisture meters and thermal imaging show where the water is and how far the growth has spread.
We trace the leak or moisture feeding the mold and get it fixed or dried before removal starts.
The work area is sealed with plastic barriers and put under negative air so spores stay put.
Moldy materials come out and get bagged. Framing is HEPA vacuumed, cleaned and treated.
We test again to confirm spore levels are back to normal, then rebuild with the same team.

Our process & equipment
Containment is the part of mold work you never see in DIY videos. It is also the part that keeps the rest of the house clean while the moldy materials come out.
Plastic barriers with zipper doors and negative air machines keep air flowing into the work area, never out of it.
HEPA air scrubbers capture spores and dust during removal and run until the final cleaning is done.
Moisture meters and thermal cameras find the water feeding the growth and confirm the area is dry before rebuilding.
Local risks
These are the mold problems we find most across Greater Seattle.

Mold on shower ceilings and behind tile from steam and leaking valves.

Mold on joists and subfloor over damp crawl spaces and leaking pipes.

Black mold on cold garage and exterior walls where condensation collects.

Roof leaks and poor attic venting that soak insulation and ceiling drywall.
Local reviews
What Seattle customers say about working with our team.
"Their team quickly identified the source of the moisture using professional moisture meters and thermal imaging cameras… They carefully removed all affected materials while maintaining proper containment. After the demolition, they thoroughly cleaned the area using HEPA vacuums and commercial-grade air scrubbers."
"He went into my crawl space and not only addressed the musty smell from mold but found the cause, which is a leaking pipe. (Out of three bids he's the only one to address the problem.)"
"We discovered mold in a bathroom wall and needed immediate help. The mold remediation process was clearly explained, and the work was done carefully and thoroughly."
"Called Green Planet because I had black mold suddenly appear on the wall in my garage. They were able to come out the next day… Mind you it was Christmas week! My garage looks like nothing happened."

Mold remediation FAQs
Yes. We inspect with moisture meters and thermal imaging, take air and surface samples when the job calls for it, and test again after remediation to confirm spore levels are back to normal.
Not if the moisture source is fixed. That might mean repairing a leak, adding or venting a bathroom fan or improving the crawl space vapor barrier. We tell you what we found and what needs to change.
For active leaks we respond 24/7. For mold inspections we usually schedule within a day or two, and we have come out the next day even during holiday weeks.
Removal means taking out the visible growth. Remediation means finding and fixing the moisture source, containing the area, removing the growth and drying everything so it does not come back. We do remediation.
Small surface spots on hard surfaces, maybe. Anything inside walls, ceilings or carpet, or larger than a few square feet, should be contained first. Scrubbing or sanding mold without containment spreads spores to other rooms.
It depends on the cause. Mold from a sudden covered leak is often included in that claim. Mold from long-term humidity or a slow leak usually is not. We document the source and the damage so you and your adjuster can sort it out.
