Homeowners and business operators in Sterling — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Sterling and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Sterling.
I manage commercial properties in Sterling and I've dealt with enough remediation contractors to know the difference.

Two years of musty smell in our Sterling basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.

Signs that warrant a professional Waterproofing inspection in your Sterling property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Sterling home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
