Dear Andrew

I want to thank you for your expert co-ordination of all the aspects of our project. I never realized the team effort involved when having not only windows and doors installed, but rebuilding my portico, and installing vinyl siding as well. 
As I work from home , I was able to observe all aspects of the job in progress and was impressed with the quality of the workmanship, and the workers\\\' care for my furnishing and flooring
The portico and siding outdoor part was multi-day due to the amount of work involved. The crews showed up all days and left the job site clean at the end of each day.
I would not hesitate to recommend you, your products, or your installation workmanship to anyone.

Best Regards
Glenn D.
