We had estimates with four companies. Nu-Sash was about the middle. but the product and timeing to install, and the friendliness of the staff made the sale. The day came to install and the installers explained exactly how they would work and the timing. The old windows came out, the new windows went in. Everythng inside the house and out was cleaned up perfectly! In the next 3 weeks, we received calls asking how the windows were and if we had any problems, and to call if anything problems cropped up. Great service, good prices.
