We had no idea our bathroom fan was venting straight into the attic until they pointed it out. The mold on the sheathing was cleaned up and they explained exactly why it kept coming back after we'd tried dealing with it ourselves.

Great communication from the first call. They tested the air, handled the removal, and rechecked the space before signing off.
Our Crestline home had mold in the basement after heavy rain. They fixed it fast and it has stayed dry.
Our process
Our attic mold removal process in San Bernardino, CA
Inspect
We check sheathing, rafters, and insulation for staining, and look at soffit and ridge vents for airflow problems.
Contain
The attic access point is sealed to keep spores from settling into the living space below during work.
Remove
Mold-affected insulation is bagged and removed; sheathing and framing are treated or media-blasted as needed.
Ventilate
We flag ventilation issues like blocked soffits or improperly vented bath fans that likely caused the problem.

Around here, attic mold removal tends to settle into roof sheathing, insulation, and rafters before anyone in the house notices it.

Good to know
Attic Mold Removal in San Bernardino, CA: common questions
How do I know if I have attic mold?
Most homeowners don't see it directly since attics aren't visited often. Signs include a musty smell near the attic access, dark staining you notice while up there for another reason, or a bathroom fan that seems to run into open space rather than outside.
Do you replace all the insulation?
Only the insulation that's wet, compressed, or contaminated. Insulation outside the affected area usually doesn't need to be touched.
Will you check my attic ventilation even if I don't have visible mold?
Yes, if you're concerned about a musty smell or just want a general check, we can inspect ventilation and moisture levels without assuming there's already a problem.
Is the attic mold removal you do in San Bernardino 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.
Is attic mold from a roof leak different to treat than mold from ventilation?
The removal process is similar, but the fix afterward is different. A roof leak needs roofing repair to stop future water intrusion; a ventilation issue needs the exhaust routing or soffit airflow corrected.
Can attic mold affect the air quality in my house?
It can, especially if there's airflow between the attic and living space through gaps, can lights, or the attic access hatch. That's part of why we contain the access point during work.
How soon can you start attic mold removal in San Bernardino?
We answer our line 24/7 and can usually reach a San Bernardino home the same day you call, sooner for an active leak.
Do you serve San Bernardino?
Yes. We cover all of San Bernardino, including Colton, Muscoy, Loma Linda, and the rest of the San Bernardino area. We are based in Crestline, about 15 minutes from our Crestline base, and answer our own phone around the clock.
