Windows in Brick or Rock

1. From the outside of the home measure the width of the opening at top, middle, and bottom.
2. Take the narrowest measurement and subtract ¼ inch. This will be the width of the window you order.
3. Measure the height of the opening at left side, middle, right side.
4. Take the shortest measurement and subtract ¼ inch. This will be the height of the window you order.
5. Repeat for each opening.

"My wife and I had several estimates from turnkey window companies and none of them came close to the quality of the Eco line of windows. As per my request, Window E-store even gave me the names of AAMA certified window installers in my area so installation was a breeze too!" - Jordan M.
"We live in a small community. The only option we had for new windows was the local lumber yard. We weren't too thrilled with the quality of window they offered. We checked out the quality of Window E-store windows and found out they are made by the top high performance window manufacturer in America. They even gave us a list of AAMA certified installers in our area! Super happy with our new windows." - Richard R.
