FAQ

Frequently Asked Questions

What should I do in the first hour of a water leak?

Stop the water at the main if you can reach the valve safely, and stay away from any electrical panel or outlet near standing water. Then call (631) 532-7346. Photograph everything before you move it, because an adjuster will want that documentation and it cannot be recreated later. Do not run fans on a suspected sewage loss. Water damage category degrades by the hour, so calling sooner is materially cheaper.

Does Greene Group Construction Corp. work with insurance companies?

Yes. We document the damage and coordinate restoration work with homeowners, insurance carriers and licensed public adjusters. Greene Group Construction Corp. performs restoration and reconstruction work and does not act as a public adjuster. Learn more about our insurance documentation support.
