Frequently Asked Questions

Q: Do I have to replace all my windows at one time?

No, there is no minimum requirement. Many of our customers come back year after to year until they finish their project.

Q: Does Excel Windows offer financing?

Our Ultra Peak Package includes 3 panes of glass, 2 panes of low “E” glass, argon gas, and foam in the frame and sash, and our Elite Package includes 3 panes of glass, 2 panes of low “E” glass, Krypton gas, and foam in the frame and sash.

Q: What are R-values and U-factor?

R-value measures the resistance to heat gain or loss. The larger the number, the better the resistance to heat flow. U-factor measures the rate of heat flow through glass, referring to how well a particular glass type will conduct heat. The lower the number, the slower the rate of heat flow.

Q: Do new replacement windows really “pay for themselves”?

Since your new windows will be energy efficient you will save money on energy costs and add value to your home. For more information refer to the Cost vs. Value Report.

Q: Will my new windows reduce condensation?

Definitely. Our Ultra or Elite glass packages keep the interior pane of glass much warmer during cold winter months than with other glass. The warmer the glass the less likely condensation will occur.

Q: What interior and exterior colors are available?

We offer many interior finishes including white, earthtone, pre-finished oak woodgrains in Golden and Dark Oak, and, of course, real wood interiors on our Pella and Marvin options. Exterior colors come in white, earthtone and dark brown along with many painted exterior colors.
