Mold Testing in Longmont, CO

Longmont, CO sits in Boulder County and is shaped by recurring St. Vrain flood exposure — mold and moisture remediation is a repeat need. Combined with pre-1985 brick and frame homes with asbestos in vermiculite attics and floor tile, that means mold in Longmont rarely stays where you first see it — it grows behind drywall, under subfloors, inside HVAC systems, and in attics long before a homeowner notices a musty smell or a discolored ceiling.

Untreated mold is more than a cosmetic issue. Certain species produce mycotoxins linked to asthma, allergies, and chronic respiratory problems, and hidden mold damage almost always triggers insurance and real-estate disclosure requirements. Getting a certified mold testing team out fast is the difference between a scoped repair and a full gut.

Our Longmont crews are IICRC-trained and follow the S520 mold remediation standard: source identification, containment, HEPA air filtration, safe removal of affected materials, structural drying, and post-remediation verification. Every job ships with photos, lab results, and a clearance letter.

In Longmont, the moisture events we see most often are roof and flashing failures after hail or heavy snow, plumbing leaks in aging supply lines, crawl-space and basement humidity, poorly vented bathrooms and kitchens, swamp-cooler and HVAC condensation, and storm or flood intrusion. Any one of those left untreated for more than 48 hours is enough to seed a mold colony.

We handle single-room remediation, whole-house rebuilds after major water events, commercial HVAC and duct decontamination, and full documentation for insurance carriers and property managers.

Our Longmont crews cover Old Town, Prospect, Meadowview, Southmoor Park and the surrounding communities. If you're not sure whether you're in our service area, call us — if we can't be there ourselves we'll refer you to someone who can.
