"The contractor scheduled our initial meeting almost immediately. When he first arrived he removed the window, that was broken, for measurement. He noted the size and explained that it would be ordered and should take 7-10 days. He followed up and let me know the progress. Once window was completed by manufacturer he scheduled the appointment to replace the window, keeping me updated and aware. He installed the window on the day he scheduled and the window looks great. I would definitely Ro again for any window needs and would recommend him as well."

"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."

"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."

"Timothy did a great job, he was very respectful and answered any questions we had. He added tints to our sky light and bedroom window and they are working great with the UV protection. No air bubbles and you can't even tell it's on there. Would use again if we need."
