What Do Our Customers Say?

”Thomas and his team are great. They take their time to make sure the projects get done correctly and exactly the way you want it. We have used them to redo our basement, front porch, master bathroom/closet and each time they have exceeded our expectations.”

Chris A, Rockville Centre

"Dear Thomas. I have been a homeowner for 35 years and have dealt with many contractors, home improvement companies, individual electricians, etc. And have never had as pleasant an experience as I have with Summit Home Improvement. The prices are fair, the work is excellent and the staff is very personable and flexible. Definitely 5 star and 5 diamonds."

Paul C, Bay Shore

"To Thomas and staff, I just wanted to thank you and express my happiness with the service I received from you and your staff. As a new homeowner, the stress of having to take care of many things can be overwhelming. You helped in making this experience pleasant. From power washing the outside, to painting, moldings, and floors on the inside, along with all the other "issues" you took care of, I simply want to thank you from the bottom of my heart. I will be calling you for my future projects and have been recommending you to all. I cannot thank you enough. Please let your “guys” know!!"

M.R. Massapequa Park

"Summit Home Improvement as your contracting company is a decision you will not regret.  The finished product is impeccable.  The price is reasonable.  The service by Thomas and his team is top notch and he takes the time to explain the process, answers/returns phone calls, and his assistant Laura was a huge aid with design decisions and ordering materials.  Most importantly, for those familiar with the world of contractors, Thomas and his team are reliable and timely in regards to the schedule provided for the project completion date.  I definitely will use Summit Home Improvement for any future projects."

Nadely B, Williston Park

"Summit Home Improvement is a great company. They were friendly, courteous, worked clean and fast. We had our basement built out into useable space and it turned out so much better than we imagined. Thomas, his crew and his office staff are great people to work with and are people who care about your results. My wife and I couldn't be happier with the service and amazing craftsmanship. We highly recommend Summit."

Tackling Common Long Island Home Headaches

We've been in thousands of Long Island homes, from split-levels in Levittown to Colonials in Garden City. After a while, you start to see the same patterns. Maybe your bathroom has tiles falling off the wall in your Lynbrook cape, or your kitchen in Oceanside is so closed off you can't talk to your family while you cook. These aren't just your problems—they're Long Island house problems.

I remember a customer in Rockville Centre who called us about a musty smell in their basement. They thought it was just an old house thing. When we went to check it out, we found it was actually due to poor ventilation and some old, leaky windows. We didn't just patch it; we installed a proper ventilation system and new, energy-efficient windows. That "old house smell" was gone for good, and their heating bill dropped the next winter. It's about finding the real root of the issue.

More Than Just a Contractor: Your Full-Service Solution

A lot of companies do one thing. We bring it all together. Think of us as your general contractor for the whole project.

We're Your Expert Remodeler

This is the big picture stuff. It's for when you look at your house and think, "This layout just doesn't work for us anymore." We change the actual structure—knocking down walls to create an open-concept living area, building that dormer addition you've been dreaming about for extra space, or reconfiguring the entire first floor for better flow.

We're Your Kitchen Renovator

The kitchen is where everyone ends up. We handle the whole job: the plumbing for your new sink, the electrical for your new lights and outlets, installing your beautiful new cabinets and tough quartz countertops, and finishing it with a tile backsplash that pulls it all together.

Bathroom Renovation

Transform your bathroom into a personal retreat. We manage full renovations, including layout changes, fixture installation, tiling, and waterproofing. Whether it's a primary suite update or a guest bath refresh, we ensure a flawless, spa-like result built to last.

Deck Building & Remodeling

Expand your living space outdoors. We design and construct custom wood decks, perform expert refinishing, and remodel existing structures. From a new pressure-treated deck for summer entertaining to restoring your current one, we build durable outdoor spaces for Long Island living.

Built for Long Island's Seasons

Our weather here is no joke. Your home's exterior takes a beating.

For South Shore homes in places like Long Beach and Baldwin, the salt air can be tough on siding and roofing materials. We use products that stand up to that corrosion.

Before winter hits, it's smart to get your roof and siding checked. Finding a leak during the first snowstorm is a nightmare you can avoid.

In the spring, it's the perfect time to look at window replacements or adding that new porch you wanted, so it's ready for summer.

The Summit Home Improvement Difference: One Call, Done Right

The biggest worry we hear from homeowners in Nassau County is, "How do I manage all these different people for my remodel?" You don't. That's our job.

We become your single point of contact. We handle the plumbers, the electricians, the carpenters—everyone. We pull the permits, schedule the inspections, and make sure every piece of the puzzle fits together perfectly. You get one project manager, one team, and one phone number to call. It's what turns a potentially stressful renovation into a smooth, predictable process.
