Frequently Asked Replacement Window & Door Questions
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.

What do exterior doors cost?

Pricing for made-to-order doors varies based on a number of factors. Door style is the most significant factor in determining front door and patio door pricing. The materials used, quality, glass package, and brand also affect the final cost.

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.
