Koppers Waterproofing has handled mold situations in Markham 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 Markham 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.
Every mold situation in Markham gets the same certified approach from Koppers Waterproofing — inspection, written estimate, S520 protocol, and air clearance before the job closes.
Mold emergencies in Markham 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 Markham is live 24/7 with real dispatchers — not voicemail, not a callback window.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Markham emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
Markham 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 Markham project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Markham area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Markham commercial inspection as standard.
Large Markham 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 Markham property, we tell you that honestly. We don't manufacture work that isn't needed.

Attempting DIY removal in Markham 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 Markham 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 Markham's humidity conditions requires addressing the moisture source directly. Every Koppers Waterproofing project in Markham includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Markham customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

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