Found black mold in our Hawthorne home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately.

That's exactly how it should work.
I manage commercial properties in Hawthorne and I've dealt with enough remediation contractors to know the difference.

Two years of musty smell in our Hawthorne 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 Hawthorne 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 Hawthorne home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
Standard homeowners insurance in Hawthorne typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure.

We communicate with your Hawthorne adjuster directly when that helps the process.
Our Hawthorne remediation is designed to last — and we back it with a written satisfaction guarantee. For customers who want ongoing documented verification, our maintenance program provides follow-up air quality checks at 30 and 90 days.
