Cheltenham homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Koppers Waterproofing delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
After inspection, you receive a complete written itemized estimate for your Cheltenham project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Cheltenham area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Cheltenham commercial inspection as standard.
Large Cheltenham commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
If inspection finds no actionable issue in your Cheltenham property, we tell you that honestly. We don't manufacture work that isn't needed.

Attempting DIY removal in Cheltenham without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
After removal, every exposed surface in your Cheltenham property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Cheltenham's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Cheltenham includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Cheltenham customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Two years of musty smell in our Cheltenham basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
