Milton's Construction has served Islip and the South Shore for four decades — licensed frame-to-finish remodeling and additions, one call away.
Islip is one of the South Shore's most distinctive hamlets — a real neighborhood of historic Colonials, Capes, and waterfront homes tucked between Champlin's Creek and the Great South Bay. The housing here has character, and it demands a contractor who respects it. Milton's Construction has been working on homes like yours since the early 1980s, and we know exactly what South Shore construction requires.
We're a licensed general contractor operating out of West Babylon, just down Sunrise Highway from Islip. We handle everything in-house, from the first design conversation through the final inspection at the Town of Islip Building Division on Main Street. No subcontractor shuffle, no finger-pointing. One team, one point of contact, start to finish.
Whether you're updating a kitchen in a century-old Colonial on Bayview Avenue, adding a bathroom to a Cape on the west side, extending a waterfront home along the bay, or installing a ductless HVAC system in a house that was never built for ductwork, we've done it on houses just like yours. Call or text us at 631-741-0199 for a free written estimate.

Islip's charm comes with real construction challenges. Many homes here were built in the mid-twentieth century on lots that sit close to the bay or along Champlin's Creek, which puts them in coastal flood zones with FEMA elevation requirements. Renovating or adding on to a flood-zone property takes a contractor who understands what the Town of Islip Building Division will require before they sign off.
We've pulled permits in the Town of Islip for decades. We know the inspectors, we understand the local code, and we manage the entire permitting process for you. You never have to chase down paperwork or wonder where your project stands with the building department.


We started doing construction work on Long Island when many of Islip's neighborhoods looked much the same as they do today. That longevity means something. We've seen every vintage of South Shore home, every quirk of local soil and flood management, and every shift in what the Town of Islip Building Division expects from a renovation project.
Our reputation is built on referrals from neighbors, not advertising. Islip homeowners talk to each other, and we've been a name that comes up in those conversations for a long time. Call 631-741-0199 and find out why.
Our crews work throughout the Town of Islip and the surrounding South Shore communities. If you're in Islip hamlet, Bay Shore, East Islip, Great River, or Central Islip, we're your local contractor. We also serve Babylon, Lindenhurst, Amityville, and communities across western Suffolk County.
No matter which South Shore town you're in, you'll deal directly with the same experienced team. We don't pass smaller jobs off to subs or change your point of contact once the contract is signed.

Yes, always. We manage the full permit application and inspection schedule with the Town of Islip Building Division on Main Street. You don't have to set foot in the building department. We handle every submission, every status check, and every required inspection from start to final sign-off.
It can, and it's important to know upfront. Bay-front and creek-front properties in Islip often fall in FEMA flood zones that impose elevation requirements and specific construction standards. We've worked on flood-zone homes here for years and know exactly what the building department will require. We'll flag those issues before you commit to anything.
We've been doing construction on Long Island for four decades, and Islip has been part of our service area the entire time. We're based in West Babylon, just a few minutes away, and we know the South Shore housing stock, the local permit process, and the conditions that come with building near the Great South Bay.
