Quick answer
Mold removal in Westchester County often follows river and storm flooding: basements and ground floors near waterways that filled during Ida, and walls that were cleaned but never dried. We extract, remove wet finishes, clean and dry to readings; national figures put water damage restoration at $450 to $16,000 and a typical remediation at $1,223 to $3,757.

What drives mold in Westchester County
Ida put as much as 14 feet of water into parts of Mamaroneck in September 2021, and Westchester County counted six storm deaths, including drivers in Harrison and Mount Vernon. River flooding at that depth reaches basements, garages and first floors, and the walls it soaked do not dry on their own.
Flooding like that leaves a long tail of mold work: finished basements that were wiped down, first-floor walls patched without being opened, and belongings stored wet. The growth shows months later as a smell, a stain at the baseboard or spots behind furniture.

Working in Westchester homes and buildings
In homes near rivers and streams, we look at the whole path the water took: where it came in, how high it rose, and which walls and floors held it. That map sets how much comes out, so we cut past the damage without stripping rooms that are dry.
For apartment and commercial buildings, we coordinate with management, contain the affected units or floors, and document the work for insurers and boards. The same order applies everywhere: water out, wet materials out, mold out, then dry.
