Providing Expert Window Replacement Services to Nashua, NH, Homeowners

New windows installed on a New England home by NEWPRO

Since 1945, NEWPRO has been surpassing the expectations of homeowners in Nashua, New Hampshire, and throughout the Northeast. We’ve become one of the most respected window replacement companies in the region by offering an array of exceptional window options and expert installation services, and we can install the perfect replacement windows for your home. When you partner with us, you’ll enjoy exceptional customer service—which has helped us earn an A+ rating with the Better Business Bureau—and the peace of mind that comes from knowing your new windows are backed by ironclad warranty protection.

We’ll Help You Find the Right Windows for Your Home

Another of the factors that helps us distinguish ourselves from other window replacement companies is the impressive selection of replacement windows we offer. Instead of a single product line, we offer three to ensure that each of our customers can find the perfect fit for their tastes and budget. You can select from popular styles like double-hung, casement, and sliding, and you can choose your preferred frame color and finish. Additionally, all of our windows come with upgrades designed to reduce heat transfer and make them more energy efficient, which could have a positive impact on your monthly energy costs.

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!

Exceptional quality and good selection. Work was scheduled quickly and installers showed up on time. They were friendly, quick and efficient, and left my home clean and debris free.
