Looks Perfect!
Leslie Cherryholmes – Plano, TX

Matt Boud, a Certified FGIA Master Window Installer, and his team installed 13 windows in our Plano home. He explained everything clearly from start to finish—no surprises. We chose Burris AC Windows with Cardinal Low-E 452 glass, and the match to our brick looks perfect. From order to install was less than 3 weeks. The pricing was fair and in line with other bids. Highly recommend Optimal Windows!

Looking for great windows without the high-pressure sales tactics? Matt at Optimal Windows is the person to call. He’s friendly, knowledgeable, and represents a quality local product (Burris / Pella) with the best glass and lifetime warranty.

Efficient & Meticulous
Anna Marie G. – Plano, TX

The last of our new windows were just installed and they’re super nice! The new windows cut down on outside noise and keep the cold out. There was no hard sell—just a fair estimate and great results. The installation was efficient and meticulous. We would definitely use Optimal Windows again.
Easy to Work With
Ben Sheppard – North Dallas, TX

We used Optimal Windows to replace all the windows in our house. The bid was competitive and the owner, Matt, couldn’t have been more genuine or easier to work with. The entire process was smooth from start to finish and Matt was on-site the entire time. Now that some time has passed, we’re already noticing reduced energy usage!
Couldn't Be Happier
Amanda Roy – Plano, TX

After getting five quotes, we chose Optimal Windows and couldn’t be happier. Matt was never pushy and kept us updated throughout the process. The results look amazing, and within one month we already noticed lower electric bills. Photos show before/after with our new Burris windows—highly recommend!
