Frequently Asked Replacement Window & Door Questions
What do windows cost?

It’s difficult to give anyone a general price estimate because there are many factors that affect the cost of a window. Unless you’re purchasing stock windows from a big box store, window costs will vary based on the manufacturer, quality, materials used, style, and the type of glass package included. We have included a pricing example for Andersen 100 Series windows in the post linked below.

Do I need replacement windows?

Many homeowners choose to update their windows for aesthetic reasons but there are other reasons why you would need to update your window. If you’re dealing with some of these problems, you should buy replacement windows:

  1. Condensation between the glass.
  2. The windows are difficult to open or close.
  3. You’ve spotted rot around or on the window.

Do you do glass replacement?

We do not offer glass-only replacement services. If you are unsure if you only need your glass replaced or need complete new windows, give us a call. Our company focuses on full window replacement which means we take out the existing windows and install new windows (frames and glass sash).
