When mold shows up in a Excelsior home or business, you need a company that moves fast — not one that books three weeks out.

Koppers Waterproofing has handled mold situations in Excelsior ranging from minor bathroom tile growth to post-flooding infestations that spread through multiple rooms. We bring the same certified standard to every job, regardless of scale.
Every Excelsior project starts the same way: a live person answers when you call, certified crew dispatched fast, thorough inspection with documented findings, written estimate you sign before work starts, and a job that closes only when post-clearance air testing confirms success.
Here's the full Excelsior service lineup.
Mold emergencies in Excelsior don't wait for business hours. When a pipe bursts, a storm floods a crawl space, or water damage creates conditions for rapid mold growth, Koppers Waterproofing dispatches immediately. Our emergency line for Excelsior is live 24/7 with real dispatchers — not voicemail, not a callback window.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Excelsior emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your Excelsior home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
We coordinate with homeowners insurance carriers in Excelsior when situations qualify. Documentation is prepared for carrier submission from day one — inspection reports, lab results, photo documentation, remediation scope, and clearance reports.
We've worked in Excelsior area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Excelsior commercial inspection as standard.
Post-remediation verification reports are provided on every Excelsior commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Excelsior commercial site assessment.
If inspection finds no actionable issue in your Excelsior property, we tell you that honestly. We don't manufacture work that isn't needed.
Pre-sale mold inspections in Excelsior are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in Excelsior, MN.
Toxigenic mold species — particularly Stachybotrys — appear in Excelsior properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Excelsior black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Excelsior 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 Excelsior's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Excelsior includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Excelsior customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

We were buying a home in Excelsior 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 Excelsior.
My Excelsior restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
Two years of musty smell in our Excelsior 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.
