Our Difference

Siding Installation on Long Island

Expert Long Island Contractors

Nassau Suffolk Exteriors is different from other Long Island home improvement companies because we have seasoned, veteran contractors in every department.

When you hire us for your renovation project, you're getting individuals with years of experience in their services area. Not only that, but each of our home improvement departments are run by an expert contractor that has worked extensively in their specialized field for at least ten years.


Modern Home Improvement Showroom

Not sure what materials or products are right for your home improvement project? Come on in to our modern showroom in Commack, Long Island to see and touch samples of decking, pavers, siding, fencing, and a wide variety of other exterior home building materials.

Sit down with one of our knowledgeable sales team members to discuss your home improvement project and view digital photos of our completed Long Island renovation projects on one of our four large monitors. You can also sit down with one of our experienced designers to have your project digitally rendered in 3D to see what your completed home improvement project will look like.

Three Year Workmanship Guarantee

At Nassau Suffolk Exteriors, our contractors and builders stand behind their work with one of the most impressive guarantees in the business — a Three Year Guarantee on Workmanship. While the majority of home improvement jobs we complete are 100% problem-free, if you do ever run into a problem with the work we’ve performed on your Long island home, we’ll be there to fix it. Guaranteed!

Exclusive Referral Program & Coupons

Our Referral Program has been designed to “thank you” for sending new clients our way and for your confidence in our abilities. When you recommend our services to a prospective client and that recommendation ultimately leads to a new exterior home improvement assignment ($2,500.00 or more), we will provide you, the referrer, with a $100.00 reward! It's that simple! Learn more about our referral program and download the latest coupons on our Special Offers page.
