Replacement Windows That Perform Reliably in the Portsmouth, NH Climate

If you can feel how hot or cold it is outside every time you walk near one of your home’s closed windows, then it’s likely time to consider a window replacement project. Heat transfer is one of the biggest culprits in high heating and cooling costs, and old windows that allow significant heat transfer can account for up to 30% of your monthly energy usage. If you’re anxious to part ways with the inefficient windows at your Portsmouth, New Hampshire, home, look to NEWPRO. We offer replacement windows that are engineered to provide excellent thermal performance no matter what the outside weather conditions are, and we stand behind our products and installations with ironclad warranty protection.

Offering NEWPRO MAX Series Replacement Windows in Portsmouth, NH

We offer “good, better, best” window options to ensure that each customer can find the perfect fit for his or her needs. However, that doesn’t mean that we offer lesser replacement windows. All our products are engineered to provide outstanding weather protection and energy efficiency thanks to:

  • Frames and sashes that are made from Celuca, a composite material that delivers better thermal performance than vinyl and can stand up to the elements without cracking, fading, warping, or rotting.
  • Multi-pane low-E glass that reduces heat transfer and UV rays
  • HeatSeal spacers that help ensure the integrity of the window seals

Thank you to the NEWPRO team for an excellent installation of our new roof (color Midnight Plum - beautiful). Everyone we worked with from the sales and installation teams were very professional, courteous, knowledgeable, and punctual. The process from pre-sale to installation was smooth and near effortless for the consumer. The installation craftsmanship, speed of demo/install, and tidiness of cleanup is truly excellent.

I have trusted NewPro on several home projects (windows, doors, siding) and have been very satisfied each time. Each crew responsible for completing the projects have all been professional and hard-working, completing each project on schedule. I will definitely be reaching back out to NewPro when I am ready to tackle the next project!
