Most restoration companies stop at mitigation — they extract water and dry your structure, then hand you off to a separate contractor for the rebuild. Greene Group Construction Corp. handles the complete process, from emergency response through finished reconstruction, under one roof.
This matters for Long Island homeowners because it means one point of contact, one insurance claim, faster completion, and no coordination gaps between the mitigation crew and the rebuild crew. We've been serving Nassau and Suffolk County since 2008.
Greene Group works directly with Allstate, State Farm, GEICO, Liberty Mutual, Travelers, and all major Long Island insurers. We prepare all documentation, meet with your adjuster, and file supplements to ensure you receive the full value of your claim.
Our restoration crews hold IICRC certifications in water damage restoration (WRT), applied structural drying (ASD), and mold remediation — the industry's highest standards. Certification ensures proper protocols that prevent secondary damage and satisfy insurance requirements.
We have crews positioned across Long Island. When you call at 2am with a burst pipe flooding your basement, we arrive fast — not in the morning. Every minute of active water damage increases your total restoration cost and mold risk.
Most damage events involve multiple types of damage. A house fire creates water damage from suppression. A flood leads to mold. Storm damage causes both water intrusion and structural damage. Having one contractor certified in all restoration types means nothing falls through the cracks.
From Valley Stream to Montauk — every community on Long Island. We've handled restoration projects in every town across both counties, and we know the local building codes, permit requirements, and insurance landscape specific to Long Island.

"Found black mold in our attic after a roof leak. Greene Group found the moisture source our roofer had missed, remediated the mold with full containment and air testing, and patched the roof. Clearance testing came back clean."
