NSI Windows and Doors is an amazing company! Jodean was extremely professional and knowledgeable throughout the entire process. I highly recommend NSI!

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.

I am pleased to say I had NSI Windows to help me through the process of replacing my old windows and doors with Impact products. The sales rep took her time to explain the windows and the installation. The installers were professional and very hard workers. I will continue to recommend this company to all my friends and family. I feel safer now with the new windows. Thank you NSI - Youre the best!!!

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.

Dealing with NSI was a pleasure from the initial meeting to completion. We replaced all our windows and sliding doors throughout the house with PGT hurricane windows and doors. During the initial evaluation numerous suggestions were made to enhance the appearance and aesthetics of the house. All questions were answered regarding the installation process, the quality, functionality, and options of the various products available, and timing of the work. NSI was prompt and on time for this initial meeting and all scheduled work days. Replacing all windows and sliders is a significant renovation. The installation team was prompt, courteous, and competent. In addition to the window and door installation itself they did everything from minimizing the dust that will result from any installation of this type to minor repairs and patching on both the inside walls and outside stucco. We confidently recommend NSI for any job. They provide peace of mind that your job will be completed timely and professionally - not to mention at a great price!

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 NSIs 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.

The team I worked with, James, Chris, and Frankie, was awesome! I live in a historical area. James knew exactly what would be approved and what would be best for the different areas of the house. He also was on site everyday checking the ongoing installation. Chris and Frankie the two gentlemen that removed, installed and fitted my new windows and doors worked tireously and continuously the entire week. The only sign, at the end of the day, that they were there was another side of the house with new windows. I had a few areas, old wooden house, that they discovered rotted wood. They replaced and repaired area and window is secure. When replacing back side door, they had to create a threshold, by cutting away 3 -4 inches of concrete, and it looks amazing. My family could not be happier with the work, the attitude, the craftsmanship, the attention to detail that went into making our house safer and more beautiful to enjoy life.THANK YOU GUYS.

Very professional and great people to deal with, one of a kind! Got awesome Windows are and superior installation!

NSI is an excellent company. They delivered my windows promptly, they were installed without drama. I shopped their price, it was fair, I recommend them

I wanted to replace four arc windows with impact windows and a friend recommended NSI Windows & Doors. I went to their website, completed and submitted a contact form, but no one called me. I called them back two days later, on a Wednesday, and provided all requested information. They agreed to show up on a Friday but would have to call me back to setup a time. I stayed home that Friday, working on a backyard project, but since no one called to setup a time, I figured they wouldn’t show. At around noon, as I walked towards the driveway, I found a business card from Lloyd E. Mitchell, an NSI sale representative. I checked the security cameras and it show a person pulling up to the end of the driveway, getting out of the car, walking towards the garage and placing what I assumed was the business card on a small shelf next to the garage.The card had a cell number, so I texted the number to find out why I wasn’t first contacted as agreed. I received a replied saying, “Did place call no answer”. I check called log and there was indeed a call, but from when the person pulled up to the driveway. And it just so happened that at that particular moment I had walked back into the backyard to pick up some tools and didn’t have the phone with me. I texted back asking if it was possible to arrange for another visit for the following week. I received the following response, exactly as written here, “No the only thing is next time in that area can call cant say when that will be.”My guess is that what Lloyd Mitchell meant to say was that he’ll call me when he’s again in the area but don’t know when. But the text sounded a little sarcastic, as if I was being punished for not answering his call. Anyway, I wouldn’t want Lloyd or anyone from this company doing work in my house. It’s obvious they have little understanding of customer service. They should have called as agreed before showing up to my house. Lloyd should have left a voice message indicating I missed his call. And I don’t understand why he didn’t knock on the door when he arrived at the house. Finally, their address show they are just 20 miles away from my residence, so I don’t understand why I must wait until Lloyd is in the area on some unknown day to arrange for a visit.

James Nuggent has an impressive knowledge of all of the many brands and styles that they sell. He makes the process of selecting and ordering windows and doors fool proof and simple regardless of ones knowledge or lack of.

Ordered PGT impact windows and doors for my house. NSI did an impressive presentation and knowledge about their trend. Windows and doors arrived on time, Superior installation, the best I have ever seen. Thank you for meeting my expectations!!

Great Service! Great Products!

We contracted out our windows in two segments, the first half was completed back in November of 17 and were so happy with NSI that we chose them to finish the second half in April. Lloyd was our sales person and walked us through the ABCs of high impact windows and helped us plan out our vision. Our installation team of John, Bill and Jeff could not have been more professional and courteous. NSI has top notch teams and would not think twice about recommending to friends.

Great job! We love our new windows. NSI did a great job and worked quickly so werent living in a construction zone. I highly recommend them.

Fabulous customer service, great windows, and an immaculate job site. What more can you ask? Jodean is magnificent. She sold me the windows, oversaw the job, and quickly replaced a window that was defective. She could not have been any nicer or more helpful.We love the new windows. They are solid, quality, and incredibly quiet! The PSG windows are the best investment we have made to our home. Thank you NSI!DANA and TOM NEIGHBORS

My experience was excellent with NSI. Top quality work was performed and the service was excellent.

Purchased windows, process was easy, sales person was extremely helpful. I highly recommend. Installers were professional and very nice

NSI Windows and Doors did a great job presenting their company and product line. The experience was wonderful and I would recommend their company to anyone.

I wouldnt go anywhere else for windows or doors. The staff is very knowledgeable and wants to help their customers understamd what they are purchasing and what would be best for the home. LOYAL CUSTOMER FOR LIFE!

Just had Lloyd stop by and give us an estimate, very nice man and very informative with no pressure.

Been waiting one week for a quote on one door. Guess the job is too small for them.
