General Contractor in Calverton, NY | All Island Construction

We respond quickly to water damage calls—whether it’s a kitchen sink leak, foundation seepage, or flood damage from heavy rains or snowmelt. Our team assesses the source, extracts standing water, dries affected areas, and repairs structural damage. Because Calverton experiences both nor’easters and tropical storms, we also reinforce basements and crawlspaces to prevent future seepage. We work with local insurance adjusters to streamline claims and get your home back to normal fast.

We start with a free consultation to understand your vision and budget. Then we provide a detailed estimate and timeline. Our crews handle demolition, plumbing, electrical, flooring, cabinetry, and finishes—all in-house. We keep you updated throughout the project and clean up daily. Since 99% of our work is referrals, we treat every remodel with the same care we’d give our own family’s home.

Absolutely. We design and construct custom ADUs, guest houses, and manufactured or modular homes. We handle permits, foundation work, framing, and all finishing. Whether you need extra space for aging parents, rental income, or a home office, we’ll ensure the structure fits your lot and meets Suffolk County codes. As a local contractor with decades of experience, we know what works in Calverton’s zoning and climate.
