"John replaced the glass sash on my Anderson casement windows. He did the complete job in one day, at a cost of 15% of the Anderson replacement window quote. I highly recommend Window MD.. They were perfect!"

"I used Star Windows and Doors LLC to replace the windows in our home. It was a pleasure to work with them - they were very responsive, and from start to finish the entire process smooth. The windows themselves look beautiful, and the installers did a great job with all the little details! I would recommend Star Windows and Doors LLC."

"Prasann was the window expert I dealt with and he was very nice in explaining the whole home genius process and giving me a good price on my windows. We went with the fusion model for the windows and he showed up to the estimate with a mask very cover friendly."

"Alex responded quickly to help me get six very old third story dilapidated attic windows replaced. He and his coworker came, measured and special ordered new windows at a fair price. They did excellent and efficient work in a difficult to work area. If you need windows replaced or repaired Wet Seal is who I would recommend. I appreciate all he did and the windows look great. Thank you Alex"

"3 month wait for window installation during pandemic. Ordered windows on October 2020 and not scheduled to be installed until late January 2021. I guess anything of good quality is worth waiting for."

"I waited a while because they are backed up due to Covid but they were definitely worth the wait. They were precise, quick and extremely detailed. They put two windows in for me (where windows didn't exist before) and covered up a window. They insulated and everything. No painting but that was cool. I was very impressed. Definitely would recommend them and hire them again...and again....and again"

"We had three older windows replaced because they were drafty and starting to show their age. The whole process was smooth, and the crew did a great job. The new windows look great, and we’re very happy with the results. I would definitely recommend them."
