Found black mold in our Lake Oswego home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Lake Oswego property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.

Two years of musty smell in our Lake Oswego 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 Exterior Waterproofing inspection in your Lake Oswego 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 Lake Oswego home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

We identify the cause, document it, and provide specific prevention recommendations for your Lake Oswego property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Lake Oswego customers.
