Austin, TX

Performance windows replaced 33 windows in our house. The quality of coming in and covering everything to the removal and replacement of the windows was outstanding. Emily and her crew did an awesome job finishing and sealing and caulking everything.  I could not be happier!!! Thank you again Performance Windows!!!

We had a great experience with Performance Windows! The installers, Emily and her crew are AWESOME! (Loved her play list) Windows are beautiful and already notice the efficiency(windows are cool to the touch on a hot day). After they finished, Anthony dropped by to check the function of the windows and go over the warranty info. Couldn’t ask for a better experience.

Incredibly high-quality experience from start to finish. Great customer service all around — windows took awhile to receive once measuring and ordering, but our install was yesterday and they had 6 enormous (8ft+ wide) windows installed in under 5 hours. The crew was incredibly efficient & professional. The windows themselves are absolutely beautiful and have taken a good 30 years off the age of our house. Would absolutely recommend to anyone looking for some top-tier energy-efficient windows!

Every person we have met with or spoken to has been great! Alex is really the star of the show! He kept me informed through the whole installation process, as well as doing amazing work!! He and his crew worked quickly and did a great job, and clean up! The windows are beautiful, and definitely changed up the outside appearance of my house! We are very happy so far! Thank you all that were involved, Thomas, Anthony, Emily, Alex and your crew!!

Performance Windows are top notch quality, for us the big selling point was the durability of the windows. Our little ones have broken a window or two with our old double panes but can’t even scratch these ones. The install revealed a hidden wasp nest where the old storm shutters were and the installers didn’t flinch. They took care of it in time for dinner, 9 window it took roughly 7 hours to install from 8 am and they did a wonderful job on the trim.

These guys knocked out my windows in a single day! Crew was super fast, careful, and professional. The new windows look great and are way more functional than the builder grade windows my house had. I can already tell the difference they are making to heat transfer as well, and expect it to extend the life of my AC unit and save me some money. They measured carefully and all of the windows fit perfectly on install day. I couldn’t be more pleased with the result. Windows are the most expensive upgrade I have had to make as a homeowner, but these guys made the money spent worthwhile.

The install crew was great! They worked clean, covering floors with plastic and carefully removing extra hardware. Moving like a well oiled machine, they had our old windows gone and new ones installed in a matter of hours. The insulating quality is obvious over the builder windows as our a/c has already recovered from having the house open all day. I am excited to see the difference in the electric bill. When the installers finished, the only evidence they were here is our beautiful windows!
