WHAT OUR CLIENTS ARE SAYING

“We used Dayside a couple years ago and were very happy with the work at the time so when we decided to get the rest of the windows done we chose Dayside again. They did a very good job. They were efficient and they did what they said they were going to do. They didn’t make idle promises they couldn’t deliver.”

“The installers were very professional, working methodically and checking every detail.  It was very pleasant having them around.  They left the door areas very tidy. Thanks!”
