Do you really answer the phone 24/7?

Yes. Water, fire and storm damage don’t keep business hours, so neither do we. Call 631-364-7827 any time, including nights, weekends and holidays, and we’ll get a crew moving.

What areas of Long Island do you serve?

We serve all of Long Island, both Nassau and Suffolk County. That includes Hempstead, North Hempstead, Oyster Bay, Long Beach and Glen Cove in Nassau, and Babylon, Islip, Brookhaven, Huntington, Smithtown and the East End in Suffolk. Because our crews are local, we can reach you fast.

Will my insurance cover the restoration?

Many types of sudden damage are covered by homeowners and commercial policies. We work with all major insurance carriers, document the loss thoroughly and can communicate with your adjuster directly to keep your claim moving.

Do I have to use the company my insurance recommends?

No. As the policyholder you have the right to choose your own restoration contractor. Many Long Island homeowners choose a local company they can reach directly.

What should I do while I wait for your crew?

If it is safe, stop the source of water, turn off electricity to affected areas, move valuables to a dry spot and take photos of the damage. Avoid using a household vacuum on water and don’t enter rooms with sagging ceilings.

Do you offer free estimates?

Yes. We provide free on-site inspections and estimates so you understand the scope of work and what to expect before anything begins.
