“I called Green Lite for a quote. I had several other quotes before I had called them. There pricing was very competitive and their product was much better. My entire experience was very smooth and professional. They did an excellent job installing my windows and slider doors. I have a very clean install. They cleaned up after themselves and put everything back the way it was when they were done. I couldn’t be happier. I highly recommend them to anyone needing new windows and or sliding glass doors. You won’t be disappointed.”

“I have been sitting here looking out my kitchen windows enjoying my spring garden. One significant difference since the last three weeks has been the NEW windows installed. The process of getting new windows took us only 3 weeks after making the decision. Our sales rep, Rodger, was knowledgeable in the products offered and clarified concerns we had. The price was fair. The install itself, and the install team, was fast and of quality work. Our five new windows are more safe and secure and will help reduce our energy use for year to come. Thank you Green-Lite Windows and Doors for a job professionally done.”
