A supply line let go in the upstairs bathroom while we were at the beach and it ran down into the kitchen. They shut the water, pulled the soaked ceiling, and dried inside the walls without gutting the room. Honest about what could be saved.
Our sump pump quit during that July downpour and the water table did the rest. The technicians arrived fast, set air movers, and checked back every day until the meters read dry. You would never know it flooded.
The water heater rusted through and flooded the utility room and part of the garage. The team extracted and dried it properly instead of just mopping. One star off only because the first callback took a little longer than I hoped.
A pipe froze over the cold snap and split behind the wall. The crew found it fast, dried the framing, and worked straight with my adjuster. Calm and respectful of the house the whole time.
A storm drove rain under our flat roof and the hallway ceiling was coming down. They tarped it, dried the attic and ceiling, and documented everything for the claim. Real local people who actually pick up the phone.
Sewage backed up into the downstairs bath and I would not go near it. The restoration team contained it, took out what could not be saved, disinfected, and cleared the smell completely. Professional from the first call.
A washer hose burst and soaked the laundry room and hallway. They were out the same day, extracted the water, and saved the hardwood by drying it fast. Fair and straight with me about the whole process.

Why South Shore homes flood, and how we plan for it
Living beside the Great South Bay shapes every water loss we see. Understanding these conditions is how our crews get ahead of the damage.
- Coastal storm surge and nor'easters push bay water into low-lying streets and basements
- A high water table near the bay seeps up through slabs and cove joints in heavy rain
- Long Island winters freeze and split pipes in exterior walls and unheated spaces
- Older housing stock with aging copper and galvanized lines that finally give out
Bay Shore water damage questions, answered
How fast can you get to my Bay Shore home?
Our dispatch is answered by a real person 24/7, and the nearest crew is usually on-site in about 45 minutes across Bay Shore and the South Shore. Water spreads by the minute, so we roll the moment you call.
Are you really available 24 hours a day?
Yes. Water damage does not wait for business hours, and neither do we. A local person answers day or night, weekends and holidays, and a crew is dispatched right away.

What does water damage restoration cost in Bay Shore?

Do you handle flooding from the Great South Bay?
Yes. Coastal storm surge and bay flooding are among our most common South Shore calls. That water is treated as contaminated, so we extract, remove what cannot be saved, disinfect, and dry the structure.
Can you dry my home without tearing everything out?
Usually. We open small, controlled access points and dry wall cavities, subfloor, and framing in place with air movers and specialty equipment, then verify with meters. We remove only what is too saturated to save.
Are you licensed and insured?
Yes. Great South Bay Water Restoration is licensed and insured, our technicians are IICRC certified, and we carry Suffolk County Home Improvement Lic. #62187-H. You can expect trained crews and a properly documented job.
What areas do you serve?
We serve Bay Shore and the surrounding South Shore of the Town of Islip, including Brightwaters, West Islip, East Islip, Islip, Brentwood, Central Islip, Great River, Oakdale, and Sayville.
