Featured Testimonials

Siding Replacement Project

The NEWPRO process was fantastic.

They showed us a full 3D rendering of the final result before anything ever got started.

Peter & Jessica
Kingston, MA

Window Replacement Project

Quality of the windows was superior to the others we looked at. Now, our windows tilt in, so it's going to be much easier to clean them.

Pembroke, MA

Pool House Doors Project

Cold stays out in the winter. Cold stays in during the summer.

The best thing I love is the craftsmanship from NEWPRO. You'd never know we had the old door cut out because it was rotted from the New England weather.

Scott Zolak

Windows Replacement Project

The sales guy was very thorough and answered all of my questions. The guys that installed the windows were fantastic.

My heating bills have dropped significantly — by about 30% than what they were before.

Ed Morneau
