"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!"

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"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"

"Excellent service! 5 star! They work fast and do great work! I spent an entire weekend trying to hire someone to install exterior shutters. The same day I contacted Zeus Siding & Windows LLC they were able to provide me with a quote and we scheduled for installation the next day! Terrific customer service. Will hire for future projects."
