About Us
At NSE Windows, we believe a beautiful home starts with trust, craftsmanship, and simplicity. As a family-owned company, we make every step—from design to installation—simple, honest, and stress-free. With Marvin Certified expertise, in-house architectural support, and a no-pressure approach, we deliver windows and doors that elevate your home’s beauty, comfort, and performance for years to come. It’s great to know an expert—it’s even better to work with one.


Our Story
Our story began with a simple belief—that homeowners deserve a better experience when improving their homes. What started as a small, family-driven business has grown into Long Island’s trusted source for beautiful, high-performance windows and doors. Over the years, NSE Windows has built its reputation on honesty, expertise, and a commitment to doing things the right way. From our first consultation to the final installation, we’ve stayed true to one mission: make every project simple, transparent, and beautifully done.
