Know the signs

Signs you may have mold

A musty, earthy odor that won't go away

Dark staining or discoloration on walls and ceilings

A recent leak, flood or long-running humidity problem

Peeling paint, bubbling drywall or warped trim

Allergy-like symptoms that improve when you leave the house

Visible growth around tubs, sinks or basement corners

What to do if you suspect mold

Don't disturb or scrub visible growth — it releases spores.

Stop the moisture source: leaks, seepage, condensation.

Keep the area closed off and avoid running fans through it.

Note any musty smell, staining or health symptoms.

Don't paint over affected drywall.

Call for an inspection before it spreads further.

Our process

How the job runs, step by step

Inspection & testing

We locate the moisture source and the extent of growth.

Containment

Negative-air containment keeps spores out of clean areas.

Removal

Affected materials are removed and bagged under controlled conditions.

HEPA air scrubbing

Air scrubbers run throughout to capture airborne spores.

Cleaning & treatment

Remaining surfaces are HEPA vacuumed and treated antimicrobially.

Repair & prevention

We fix the leak, rebuild and advise on keeping it dry.
