"Removed existing windows. Replaced 17 openings with Andersen double hung and casement windows with insulated glass, full screens and airspace grills. The work was completed as scheduled, clean-up was well done. The workers were pleasant and diligent. Follow-up was completed promptly and efficiently. We were pleased with the personal contacts and the installation.
