What happened?

What kind of damage are you dealing with?

Most calls start with one of five problems: water from a pipe, appliance or the apartment upstairs, a fire, the smoke and soot it leaves behind, a storm that flooded the basement or brought a tree down, or mold that grew where moisture sat. Pick yours to see how we handle it.

Our home town

Why does Harrison see so much water damage?

Because of where its water runs. Beaver Swamp Brook rises at the Westchester Country Club, Brentwood Brook crosses downtown under Halstead Avenue, and Blind Brook runs through Purchase. Harrison has had 949 flood insurance claims and 94 repeat-loss properties, according to the county’s 2021 hazard plan.

New York State’s 2024 Beaver Swamp Brook study found that along Brentwood Brook, between I-95 and the Metro-North line, the concrete channel is about half the recommended width and the railroad berm acts like a dam; 18 properties there had repeat flood losses. Irene put Oakland and Park Avenues under water in 2011, and residents told the county that the sewers in the Harrison Trails area back up into houses in heavy rain.

During Ida in September 2021, a rain gauge less than half a mile from our office recorded 7.09 inches. On July 21, 2026, an EF0 tornado started on the Manhattanville campus in Purchase while Anderson Hill Road flooded.

How it works

What happens after you call Strongwater?

Four stages, one company. You call and we set the first visit. On site we stop the damage from spreading. Then the building is dried and cleaned, guided by moisture readings rather than guesswork. Last comes the rebuild, by the same team that started the job, so nothing gets lost in a handoff.

Call (718) 357-9191 and tell us what happened, where, and how long it’s been wet or burning.

Dry & clean

Property managers & boards

Managing a building? We work the way buildings work.

Much of our work comes from managing agents, co-op and condo boards and building owners. We document every affected unit and common area, coordinate access with residents, and follow the scope the building approves, from a single leak between apartments to a fire that touched 28 units.

FAQ

Restoration Questions, Answered

Straight answers to what people ask us most. Don’t see yours? Call and ask.

Call (718) 357-9191

Shut off the water if you can find the source, turn off power to that area only if the panel is dry, and move valuables out of the way. In an apartment or co-op, call the super so the unit above gets checked. Then call (718) 357-9191 and we’ll tell you what to do until the crew arrives.

Yes. Our line is answered around the clock, every day of the year, and for emergencies our crews aim to be on site within two hours. If water is still coming in, call (718) 357-9191 rather than sending the form.

No. Estimates are free: we inspect the damage, explain what needs to happen and give you the scope before any work starts.

Water, fire, smoke, storm and flood damage, mold, sewage backups, asbestos and lead paint, plus the reconstruction that follows. For commercial buildings and property managers we take on large, multi-unit and multi-floor losses, and we also offer estimating, appraisal and expert witness services.

Yes, a lot of our work is in managed buildings. Leaks travel between units, so we check the apartments above, below and beside the source and coordinate access and scope with the managing agent or board.

Your insurance company decides that, based on your policy and the cause of the damage. We document the damage with photos and moisture readings, write a detailed scope, and can walk through it with your adjuster. We don’t promise coverage or negotiate claims.

Our office is at 111 Calvert Street in Harrison, NY 10528, close to the Harrison Metro-North station. From there we cover Westchester County, Fairfield County in Connecticut and New York City.
