    Our new windows had their first test in recent thunderstorm with strong wind off the lake, no leaking. We are pleased that existing wood trim could be saved as it is continuous through out the house. The wood stain used on wood framing up windows matches well. Installing process was smooth, all people were very professional and did a great job. We hope the windows will function as well as they look .

    The new windows installed in the bathrooms & bedrooms look great. The reason question #5 only got 4 stars, was because a couple of the windows we had installed last fall leaked air from outside and had frost on the inside on minus 20*F days. The workmen took the time to fix the problem.

    The installers were very professional and courteous - even taking their shoes off entering the home. Their clean up was so meticulous tat I didn't need to re-vacuum. They worked from the time they arrived til they left, taking no time out for a break. I commend them!
