Framing basement window openings in your basement walls is a quick and painless affair! There are many ways to “skin a cat” as they say, so i’m giving you my way accomplishing this task, it’s worked very well for me over the last 22 years of framing basements.

I frame my walls as though there is no window present in the exterior basement wall. Yep that’s right! I first fully frame each window wall right in front and over-top of the windows as if they weren’t there, and then I go back and “cut-out” each window penetration after the fact. Now some people may say why don’t you just frame in the window as you frame each window wall at the same time your framing the wall? Well, I got a reason for why I frame basement windows this way, and ONLY basement windows this way…

The reason is, Basement floors are not level and walls in the basement tend to run up and downhill right in front of the windows. But, the windows installed by the builder are NOT running up and downhill. If I frame my windows into the wall before I “set” my wall in position to be fastened  the window framing would then run up and downhill along with the floor causing my windows to be out-of-square! By cutting my windows out after-the-fact, I can now use my levels to mark my cut-out’s making sure that my window framing is perfectly level and plumb. This may sound a little confusing at first, but trust me it’s the BEST way to approach framing windows…and, it’s simple to do.

The tools needed to frame basement windows include the:

  • Circular saw
  • Reciprocating saw
  • 2′ and 6′ levels
  • Carpenter Pencil
  • “Speed Square (small Rafter square)
  • Air-Framer Gun
  • Power Miter Box

Knowing where to cut into your framed wall for this framing procedure is critical to your window framing success. The video above will give you a good education for framing windows in your basement. Make sure you wear your eye and ear protection when performing this operation in your basement.

Remember to always “Measure twice and cut once” just to be sure, it saves you both time and money!
