Quick answer
Mold removal on Staten Island most often follows flood water in basements, damp crawl spaces under older bungalows and additions, and attic condensation in single-family houses. National guides put basement mold removal at $500 to $3,000 and crawl space work at $500 to $2,000; we dry first, remove what grew and cover exposed ground.

What drives mold on Staten Island
Sandy pushed a 14-foot surge onto Staten Island in October 2012, and in Midland Beach, South Beach and New Dorp soaked insulation and belongings were pulled from flooded basements for weeks. In Oakwood Beach, most homes were bungalows built between 1930 and 1950 on former salt marsh, and 196 of them were bought out and demolished after the storm.
Rain adds to it. Ida left nearly 9 inches of rain on Staten Island in 2021, filling basements the ocean never reached.
Staten Island also has the highest homeownership rate of the five boroughs, 61.7 percent in the 2017 city survey. Owner-occupied houses bring their own hidden spaces: basements, crawl spaces under additions and porches, and attics where winter condensation grows on the roof deck.
Jobs we do most on Staten Island
Most Staten Island calls involve a house and a space nobody looks at often. These are the jobs that come up most.
Flooded Basement Cleanup
Pump-out, tear-out and drying after storm water fills a basement.
Basement Mold Removal
Growth behind finishes in basements that flooded before.
Crawl Space Mold Removal
Joists and ground cover under bungalows, additions and porches.

Water Damage Restoration
Burst pipes and appliance leaks dried before mold starts.
Dehumidifier Installation
Drained units for basements and crawl spaces that stay damp.
Working on Staten Island houses
In neighborhoods that have flooded before, we check the bottom of basement walls and the framing behind finishes even when the surface looks fine, because an old flood can still be in the walls.
Low ground keeps crawl spaces and slabs damp from below. Covering exposed soil with a vapor barrier and running a drained dehumidifier are often the difference between a job that holds and one that returns.
