Why Energy-Efficient Windows Matter

Outdated or poorly sealed windows let indoor air escape — and outdoor air creep in — making your HVAC system work harder. The result? Rising energy costs, uneven temperatures, and an uncomfortable home.

Modern energy-efficient windows are designed to stop that.

With our window installation, you’ll get:

  • Improved Indoor Air Quality
  • Better sound insulation
  • Protection against UV damage
  • Lifetime warranties that are transferable (this helps home resale value!) 
 

When properly installed, energy-efficient windows offer real returns — in comfort, cost savings, and long-term value.

It’s not just about the window you choose — it’s how well it’s installed. Whether you’re upgrading your home in Connecticut or Massachusetts — our team is ready to help you choose the right windows and we seal every unit properly, match your trim, and ensure long-term performance.

We provide expert window installation, personalized recommendations, and we understand the unique climate challenges across our broader service areas. When you schedule a consultation, here’s what you get:

The communication with Nu-Face for this project was really exceptional. The door itself is very well built and looks great. Installation was very quick, about an hour and the installers did a good job of protecting the area around where they were working.

Scott did a great job installing our new garage windows. Very personable and nice. He came back for a service call and once again, did a great job!

We had used Nuface for siding and another project and when the time came for a new roof we went to them immediately and we are glad we did. Ramon, the supervisor, said they would get it done in one day and they did, working until 9pm to get the roof finished and all the cleanup done. Danny and his crew did an exceptional job, very clean and efficient. And Ramon was wonderful, even saving us money on the bill. When it comes to our next project we will go straight to Nuface.

Scot was very professional and a pleasure to deal with. He provided a temporary latch and just installed the permanent replacement. Highly recommend him

2020: My husband and I have used NuFace for two projects on our house so far. They first did our windows, which turned out excellently. The team worked efficiently for a 1-day install, and we have noticed a difference in the temperature of our house. Because of this marvelous work, we also went with NuFace for our siding and for new gutters. This big project took 4 days, and went very efficiently again. It gave our house a stunning new look. The only down side we found in our overall experience was that there wasn't clear communication with the material companies, the NuFace crew team, and the leadership. For both projects, materials arrived after the work crews did. Overall, we are extremely pleased with the appearance and the quality of the materials and the workmanship of the NuFace crew. Both times we worked with sales rep Al Gyurko, who was great to work with and is an excellent representation of the professionalism and care that NuFace has with its customers. Ask for Al if you go with NuFace! Update 2026: NuFace’s service department helped us with a window seal failure. Scott was efficient and professional!

Update! We had a new garage door put in by another company and they accidentally dented the siding. Scott from Nu-Face came out and had it fixed in no time. He also came out to replace a window that had cracked and was done in 10 minutes! Very professional and personable. Nu-Face came through again! Could not be happier with Nu-Face and the entire team. The PMs Ramon and Jenn kept us informed and things running smoothly. Dave and his team had every window in our house installed in one day and left the house immaculate. And I can’t say enough good things about Edgar and his siding install team. They were the hardest workers I’ve ever seen and did an amazing job. The transformation of our home is incredible. Thank you Nu-Face!

Everyone at Nu-Face was absolutely fantastic while planning for my bathroom remodel! From Chris in sales to Alyssa at the office, I knew every option available to me and when I could expect the install to start. Alfredo, the man the myth the legend, is one of the most professional and knowledgeable installers I could have ever hoped to get for this renovation. Not only was he quick and efficient, he made sure he kept the house clean as he moved through and left the workspace spotless at the end of the day…which is surprising considering how much demo work had to be done. The man clearly knows his stuff and I consider myself lucky to have had him over to do this work. At the end of the 4 day install I’ve got a beautiful bathroom and I couldn’t be any happier! - Jim in Hamden, CT
