We had a musty smell in the hallway for months with nothing visible anywhere. The team used a camera to check inside the wall and found mold from an old leak we didn't even know about. Glad we finally had it checked.

Reviews
Rated 4.9 by Lake Arrowhead-area neighbors
Called about a musty smell and they walked me through every step before starting. The area was contained properly and the odor was gone when they finished.
Our Crestline home had mold in the basement after heavy rain. They fixed it fast and it has stayed dry.

Good to know
Hidden Mold Remediation in Lake Arrowhead, CA: common questions
I smell mold but can't see any. What should I do?
A persistent musty smell with no visible source is worth having inspected. We use moisture meters and cameras to locate hidden mold without unnecessary demolition.
Can hidden mold make a home smell musty without being visible?
Yes, mold growing inside a wall cavity, under flooring, or behind a cabinet can produce a noticeable smell well before it becomes visible on a surface.
Is hidden mold more dangerous than visible mold?
It isn't inherently more dangerous, but it often goes untreated longer since nobody knows it's there, which can let it spread further before it's addressed.
How do you keep the mold from coming back after hidden mold remediation?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Lake Arrowhead home.
Will you have to cut open my walls?
Sometimes a small opening is needed to confirm and access hidden mold, but we always try to locate it first with non-invasive tools to keep the opening as small as possible.
How do I know if past water damage left mold behind?
If an area was wet in the past and the smell or discoloration returned later, it's a strong indicator that moisture remained trapped inside a cavity.
Is the hidden mold remediation you do in Lake Arrowhead to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across San Bernardino County.
Do you serve Lake Arrowhead?
Yes. We cover all of Lake Arrowhead, including Fredalba, Smiley Park, Running Springs, and the rest of the Lake Arrowhead area. We are based in Crestline, about 10 minutes from our Crestline base, and answer our own phone around the clock.
