Replacing my parents' original builder-grade windows in their 25+ year old home was one of the best investments they've made. The entire process was easy and straightforward, and the installation crew was professional, courteous, and left everything spotless. Their old windows had broken seals, cloudy glass, and most wouldn't even open. The new windows have completely transformed their home. They've already noticed lower electric bills, less outside noise, and a cooler, more comfortable home th... Read more

Thank you so much for taking the time to share your family's experience! It means a great deal that you trusted us with replacing your parents' original builder-grade windows. We're thrilled to hear they're already enjoying a quieter, cooler, and more energy-efficient home, and that the bronze exterior windows and updated design gave their home the fresh, modern look they were hoping for. The photos you shared are fantastic and really showcase what a difference the new windows made. The bronze exterior paired with the brick and stone looks absolutely beautiful! Our team takes pride in providing a smooth installation process while treating every home with the same care and respect we would our own. On behalf of everyone at The Window Source of Houston, thank you for your recommendation and for allowing us to be part of such a meaningful home improvement project. We hope your parents enjoy their beautiful new windows for many years to come! Regards, David Mallette Owner

5/5
The 16 replacement windows were installed in less than a day, about 7 hours. The workers first provided dust protection plastic sheeting over all the interior furniture, counters and on the outside only a few places were needed it. They only had a few windows open at a time so when it got hot outside I stayed in a back room with a TV. The workers were friendly and very professional. You could tell they had done this work before. I had some finished millwork in 2 of the rooms that they trimmed ne... Read more

5/5
We had 24 windows replaced. This company was amazing from the salesman all the way thru to the finish. Luis and his team were absolutely amazing. I was completely satisfied. There was one mistake but it was promptly taken care of. I couldn’t be any happier with the new windows. My old double pane windows didn’t keep the heat out anymore (26 yrs old). I was so impressed at how much cooler our house is w the new windows. Everything was put back (curtains, rods, blinds) and cleaned up. All trash c... Read more
