Construction & Remodeling in Holbrook, NY

Your Local Holbrook Contractor

Milton's Construction has been working in Holbrook and across central Suffolk County for over forty years. We're a frame-to-finish design-build contractor — licensed and insured in New York, New Jersey, and Pennsylvania — and one in-house team handles every part of your project from the first drawing to the final inspection.

Holbrook is mostly Town of Islip, with a portion falling under Town of Brookhaven, so permits route to the right Building Division depending on exactly where your lot sits. We know both processes, and we pull and manage permits and inspections so you don't have to track that down yourself.

The housing stock here is what we love to work on — 1960s and 1970s ranches, high-ranches, and Colonials on full lots, with real room to grow up or out. If you're thinking about a second story, a rear addition, a kitchen overhaul, or heating and cooling for an older home, call or text us at 631-741-0199 for a free written estimate.

Serving Holbrook Homeowners for Over Four Decades

We've been building and remodeling homes in the Holbrook area since long before the hamlet became as busy as it is today. Over the years we've worked on ranches off Grundy Avenue, Colonials near the Holbrook Country Club corridor, and high-ranches throughout the ZIP. That on-the-ground experience matters when it comes to soil conditions, existing construction methods, and what local inspectors expect.

Being close to Long Island MacArthur Airport means Holbrook sits in a well-connected part of central Suffolk — which is useful for material deliveries and keeping our crew on schedule. Neighbors in Ronkonkoma, Sayville, Bohemia, and Holtsville know us too, so references from projects nearby are easy to come by. Call 631-741-0199 and we're happy to share them.

• One in-house crew from design through final walkthrough
• Permit and inspection management for Town of Islip and Town of Brookhaven portions

What We Build in Holbrook

Most of our Holbrook work falls into a few categories: kitchen and bathroom remodels inside the home, room additions and second-story builds that take advantage of the full lots, and HVAC upgrades for houses that were built without ductwork or that have older systems that can't keep up. We do all of it under one roof — no subcontracting the framing to one company and the finish to another.

Full lots in Holbrook give homeowners real options. A single-story ranch can become a true two-story home. A hi-ranch can get a rear extension that nearly doubles the living area. We size the foundation or the existing structure honestly before any promises are made, and we put the scope in writing before a shovel goes in the ground.

How to Get Started

Call or text 631-741-0199 at any hour and leave a message if we're on a job. We'll come out to your Holbrook property, walk the space with you, and put together a free written estimate that covers scope, materials, and a realistic timeline. No ballpark numbers over the phone — a written estimate is the only kind that protects you.

Once you're ready to move forward, we handle the permit application with the appropriate Building Division — Town of Islip for most Holbrook addresses, Town of Brookhaven for parcels in that jurisdiction — and we schedule and attend all required inspections. You keep the paperwork.
