"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."

"Steve and Alex were incredibly great. I was referred by another company when needing a large decorative mirror hung in a dining room. Steve and Alex were extremely professional. Called prior to arrival and were very courteous and did an outstanding installation in record time and with what appeared to be ease and expertise. I would absolutely recommend them and consider the pricing an incredible value for the services provided in my home. Would hire them for this and other glass and mirror installations in the future in a second!"

"I Love the windows. The installation crew were sloppy. They left debris from the old windows (nails)all over my deck and Patio. The new windows created their own mess leaving behind sharp metal shavings from the casing used to wrap the windows. The caulking looked like a toddler did it with a dry finger. On my foyer window the suction cup marks are still on it. On another window the casing was installed to make the window appear crooked. If they just examined their work after they finished they would have observed their poor craftsmanship and corrected it on the spot. We are very unimpressed by the install team. Also they took out a chunk of my hardwood floor by my front door."
