About

Northcrest Window & Door Specialists is a locally owned window and door replacement company based in Derry, New Hampshire. We help homeowners in Derry, Londonderry, Windham, Hampstead, Chester, and the surrounding communities upgrade their homes with quality Andersen windows and ProVia doors, professionally installed by a team that takes pride in getting every detail right.

Our approach is simple: honest advice, quality products, and craftsmanship you can count on. Every project begins with an in-home consultation and our Window Health Check, where we use thermal imaging to show you exactly where your home is losing heat and energy. No pressure and no gimmicks, just a clear picture of what your home needs so you can make the right decision for your family.

What we offer:

• Replacement windows from Andersen (100, 200, 400, A-Series, and E-Series)

• ProVia entry doors and patio doors

• Full-frame window and door replacement

• In-home consultations and thermal imaging Window Health Checks

Whether you're replacing one drafty window or updating your whole home, we'd be glad to help. Call (603) 421-4461 or visit northcrestwindows.com to get started. And if you spot our truck around town, or Margot, our golden retriever and official company mascot, be sure to say hello!
