Mold Remediation & Mold Removal in Portola Valley, CA

Portola Valley homes sit among wooded hillsides and creeks, where shade, slope and winter rain keep moisture near foundations.

Anderson Group International’s mold remediation team serves Portola Valley homes and businesses, finding the moisture behind the mold and removing it safely. Call 1-800-994-7575, 24/7.

Why Mold Grows in Portola Valley Homes

Shaded, wooded lots stay damp long after the rain stops. Crawl spaces, basements, north-facing walls and roofs under heavy tree cover are where mold takes hold.

Signs You May Have Mold

A musty, earthy smell that’s stronger in closets, bathrooms or under the house
Dark spots or fuzzy growth on walls, ceilings, window frames or cabinet backs
Peeling paint, warped baseboards or soft drywall near plumbing
Allergy-like symptoms that ease when you leave the house

When to Call a Professional

The U.S. Environmental Protection Agency says homeowners can usually clean mold patches smaller than about 10 square feet. Call a professional when the mold covers a larger area, keeps coming back, is inside walls or ducts, or followed sewage or flood water.

Our Mold Remediation Process in Portola Valley

Find the water: Every mold job starts with locating and stopping the moisture source.
Isolate the area: We seal the work area and run HEPA air filtration under negative pressure.
Remove and clean: Affected materials come out, and salvageable surfaces are cleaned and HEPA-vacuumed.
Dry and restore: We dry the area, confirm readings are normal and rebuild walls, floors or cabinets as needed.

Because mold almost always starts with water, fixing the source comes first. If a leak or flood caused it, our water damage restoration team can dry the property before mold removal begins. Learn more about our mold remediation and mold removal services.

Frequently Asked Questions

Will bleach kill mold?

Bleach can lighten mold on hard, non-porous surfaces, but it doesn’t remove mold that has grown into drywall, wood or insulation, and it does nothing about the moisture that caused it. Those materials usually need to be removed and replaced.

Is mold testing necessary?

If you can see mold, testing usually isn’t needed to decide that it should be removed. Testing can help when you smell mold but can’t find it, or to confirm an area is clean after remediation.

Do you serve areas near Portola Valley?

Yes. Our mold team also works in Woodside, Menlo Park and Palo Alto.

Testimonial

Trusted by millions of Customers

The Lead Technician and support Technician that came out the previous two days at another job in the complex were extremely impressive with their skills and the communication in front of the homeowner. I am very impressed.

He made the process run very smoothly, and as I said, he checked in on us during the process to make sure that we were happy with the services we were receiving. Additionally, he made sure that the mold levels were testing at normal levels and made suggestions that eased my mind and helped us learn how to avoid future issues. I would definitely recommend him and AGI.
