FAQ
What areas do you serve?
We serve Suffolk County, Long Island—including the East End (Hamptons + North Fork) plus central and western Suffolk on both the South Shore and North Shore. If you’re unsure about coverage for your town, send the address and timeline and we’ll confirm availability.
How quickly can you schedule?
Scheduling depends on season and scope. If you have a real estate deadline or an active moisture event, tell us your timeframe and we’ll recommend the best next step.
What’s the difference between a mold assessment and mold remediation?
There’s no government “safe/unsafe” cutoff for mold results. We’re also not medical professionals, so we don’t make health determinations about whether something is “safe” or “unsafe.”
What we can do is classify conditions as normal (typical background) or abnormal (elevated / consistent with a source) based on what we observed onsite, building history (leaks, humidity, ventilation), and—when sampling is done—comparison to an appropriate baseline/control.
