We kept getting mold on the same bedroom window every winter and finally had it looked at properly. Turned out it was a ventilation issue as much as the window itself, and the team explained exactly what was happening before doing the cleanup.

We had mold after a slow leak under the sink. They inspected it, explained the plan, and left the space dry and clean.
Our crawl space mold was worse than we thought. They handled the full remediation and installed a vapor barrier too.

Good to know
Humidity & Condensation Mold Control in Northwest Harbor, NY: common questions
Can New York's dry climate still have a mold problem?
Yes, condensation from temperature differences, humidifiers, or poor ventilation can create localized humid spots even in a generally dry climate.
Can a humidifier cause mold?
Yes, evaporative coolers add significant moisture to indoor air, and if it isn't managed well it can lead to condensation and mold near ducts and vents.
Do you check ductwork for condensation mold?
Yes, we inspect ductwork and register boots since sweating ducts in a crawl space or attic are a common and often overlooked source.
Will my insurance cover humidity & condensation mold control in Northwest Harbor?
It depends on the cause. When the mold follows a sudden, covered event, there is often coverage. We bill your carrier directly and document the loss so your Northwest Harbor claim moves.
Why does mold keep coming back on my window sill?
If condensation keeps forming, wiping the mold away is only a temporary fix. The underlying humidity or insulation issue needs to be addressed.
Is condensation mold less serious than mold from a flood?
It's typically smaller in scope, but it can still spread if left unaddressed and the underlying humidity issue is not corrected.
Do I need to leave my Northwest Harbor home during the work?
Usually no. We seal the work area under negative air, so most of the Northwest Harbor home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Northwest Harbor?
Yes. We cover all of Northwest Harbor, including East Hampton North, Springs, East Hampton, and the rest of the Northwest Harbor area. We are based in Sag Harbor, about 5 minutes from our Sag Harbor base, and answer our own phone around the clock.
