Smithtown 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 Smithtown project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Smithtown area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Smithtown commercial inspection as standard.

Not sure if your Smithtown property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Pre-sale mold inspections in Smithtown 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 Smithtown, NY.
Attempting DIY removal in Smithtown 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 Smithtown 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 Smithtown's humidity conditions requires addressing the moisture source directly.

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

That's exactly how it should work.
My Smithtown 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.
Called Koppers Waterproofing for a Smithtown crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost.
