Purchasing new or replacement windows or doors can be overwhelming. Not only do you have to choose the style, you have to choose a manufacturer. We want to make your decision easy. That’s why we offer a Lifetime Warranty on our windows and doors, whether you buy them directly from Dayside or from one of our dealers.

If you purchase Dayside windows or doors from a dealer, they will provide service and Dayside will provide any parts required to perform service.

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!”
