Frequently Asked Replacement Window & Door Questions
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.

How are replacement windows measured?

We take multiple horizontal and vertical measurements of the window to determine the smallest points of the window as well as the window depth. That allows us to order a properly sized window that’s not too big for the opening and not small enough to leave big gaps around the window frame.

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).
