Sometimes the best way to rate a company is how they deal with a problem down the road, after the original install. Recently had a problem with the impact door they installed. Texted Lloyd and he answered quickly and they were able to send a friendly service tech the following day and resolve the issue. Now this was 8 months after the original install. Tons of window companies out there, but finding one who stands buy their product after install with prompt service now that is a rare find these days. Would recommend them to anyone and Lloyd our contact/sales rep was awesome.

I love my new front doors and impact sliders from NSI Windows & Doors! Jodean was so patient and knowledgable in helping me make the right selections for my home. I am very happy with the quality of the products. The installation went very smooth and the overall cost was well within budget. Thank you, NSI, I’ll definitely be using you to upgrade all of my windows too!

NSI did an excellent job from the quote to the installation. Jose the sales rep was very professional and assisted us in making the proper selection of sliders and windows. The installation team was neat & professional. Very good communication throughout the entire process. I highly recommend NSI Tom The Ridge at the Bluffs

I had all of my windows installed yesterday and it was a great experience. The gentlemen were excellent! I’ve heard how messy and dirty it can be; they made sure everything was clean and even washed the windows. Highly recommend!

DO NOT USE NSI! They installed hurricane doors and windows at our parents’ condo in Palm Beach. Within 5 years, the doors and windows failed completely, the frame totally corroded and pitted out, allowing water to enter and salt to build. NSI refused to take any responsibility for the terrible workmanship. We are now spending thousands of dollars to install new hurricane doors and windows. Do not let this happen to you.

Did a great job installing my impact resistant doors and windows. Replaced several sliding glass doors with French doors, which I love. When one hurricane lock was stuck after 3 years, they fixed it in 15 min. And when the same set of doors was leaking after four years, they came out several times to figure out what was leaking and to fix it. Everything was fixed and they left the house looking better than it did before they were here. Thank you.

We just had NSI Windows replace all our windows with impact glass and we couldn’t be happier. This was a big job and the installers, Tony, Noilan and Alfredo worked non-stop to complete our job on schedule. They were conscientious, detailed, neat and very respectful to us and our home and the job they were trusted to do. We would totally like to recommend them as we are 100% satisfied with their installation experience and knowledge required to do an excellent job. And, when we committed to purchase our PGT Custom windows, we were given an installation date and that is the exact date that our installation began! They look amazing and are excellent quality at a fair price. Bye, bye 34 year old windows and hello beautiful windows!

NSI has an amazing reputation. We are so delighted with our impact window decision, from our initial consultation with Jodean, who is so very knowledgeable & professional, through the flawless installation process, with NSI’s courteous, friendly & professional installers. Additionally, I wish to personally thank the company for providing the same experience to all I have referred to your care. Highly recommended.
