    Installer had to leave twice. Once to get wood trim for windows and the other was to get concrete drill bits. Job was to install 3 48x48 basement windows

    Installer was awesome, his helper needs improvement. Setting nails, caulking, and trash pickup by his helper were doe by homeowner.

    Love these windows! Just wish they weren't so pricey. Communication on scheduling wasn't nearly as good as in the past and needs improvement. When a customer gives you a phone number to contact, please update your records and use THAT number. Would have saved unnecessary angst on everyone's part.
