Frequently Asked Questions

Burris Windows and Cardinal Glass are proudly made in FT Worth and Waxahachie, Texas.

Pricing can vary based on many factors. The window products you choose, the difficulty of the installation, the quantity of units you purchase, and the colors and grids you select. That is why we offer free, no obligation, proposals so that you can have exact numbers, in writing, before you make any decisions about your project. We never pressure you to purchase from us. We believe that if we have what you need, and we can do it at a fair price, you may consider us for your project.

We have the fastest industry lead times. Your custom windows and sliding patio doors will be made in 3-4 weeks.

We carry worker’s compensation and liability insurance on all of our staff.

Yes, the safety of our staff and the protection of your home are our number one priority. You will find that our process is built around protecting your home and treating it the same way we would want it to be treated if we were getting new windows and doors installed in our own homes. This means that we always wear the proper safety gear to protect our staff and we always take the extra steps to cover your furniture and flooring so that they are protected from any issues that may occur during the installation process.

 All we ask from you is that you remove any window blinds or curtains and breakable valuable items from the working areas prior to our arrival. (expensive art, china, trinkets, grand pianos, irreplaceable items, and items of sentimental value).

Our priority is to take as much time as we need to do things properly and to never cut corners. However, we understand and value the importance of getting things done so we can return your home to you as soon as possible. Most projects take one or two days to complete. Please ask us for an estimate on how long we think your project will take.

We are proud of our work and love to it show off. We welcome you to drive by some of our projects in your area. And, we could even arrange a time for you to visit one of our active installations with prior notice. (We would always need to clear the invitation with our client before you would visit an active project). Ask us for details about projects near you.

Unless you request otherwise, all of our windows and sliding patio doors are going to be produced with today’s best glass technology by Cardinal Glass  to ensure that you get a high-efficiency product that provides you with the benefits of a more comfortable home and a reduction in energy cost.

Of course. We can offer you just the windows if you have your own installer. Either way, you can take advantage of a 5-Star experience that will leave you feeling great about your experience with Optimal Windows. We would love to help with your project.
