Why Longmont Homeowners Call Us

Local Testing, Not a Generic Checklist

Know the Signs

Signs Longmont Homeowners Should Watch For

A musty smell that doesn’t go away with normal cleaning, visible discoloration on drywall or around windows, recent water damage that wasn’t fully dried out, or allergy-like symptoms that ease up when you leave the house are all reasons to get a property tested. In Longmont specifically, basements, crawl spaces, and areas near HVAC or swamp cooler ductwork are the most common places we find hidden moisture, so those are worth mentioning when you call.
