    After the salesperson left all of a sudden buyers remorse hits - did we do the right thing?Do we need these windows? Yes we did. They are wonderful. The crew who installed them were efficient. I drove up the driveway after work and looked at them (we did not have all replaced and was worried about how they looked with other older windows) they looked great and just blended in and just happy we had the windows replaced.

    Installers were extremely courteous, neat and clean. The windows seem to work well. They are expensive!
