We had a musty smell in the hallway for months with nothing visible anywhere. The team used a camera to check inside the wall and found mold from an old leak we didn't even know about. Glad we finally had it checked.

Good to know
Hidden Mold Remediation in Shelter Island Heights, NY: common questions
I smell mold but can't see any. What should I do?
A persistent musty smell with no visible source is worth having inspected. We use moisture meters and cameras to locate hidden mold without unnecessary demolition.
Can hidden mold make a home smell musty without being visible?
Yes, mold growing inside a wall cavity, under flooring, or behind a cabinet can produce a noticeable smell well before it becomes visible on a surface.
Is hidden mold more dangerous than visible mold?
It isn't inherently more dangerous, but it often goes untreated longer since nobody knows it's there, which can let it spread further before it's addressed.
Do I need to leave my Shelter Island Heights home during the work?
Usually no. We seal the work area under negative air, so most of the Shelter Island Heights home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Will you have to cut open my walls?
Sometimes a small opening is needed to confirm and access hidden mold, but we always try to locate it first with non-invasive tools to keep the opening as small as possible.
How do I know if past water damage left mold behind?
If an area was wet in the past and the smell or discoloration returned later, it's a strong indicator that moisture remained trapped inside a cavity.
How soon can you start hidden mold remediation in Shelter Island Heights?
We answer our line 24/7 and can usually reach a Shelter Island Heights home the same day you call, sooner for an active leak.
