How to install Basement Windows on a Block wall?
So I need to replace our ancient windows in our basement. We have a block wall with the cut out for the windows at the top. The top edge of the widow is against the wood base of the walls.

Most windows I see have the Flange part that sticks out around the window like you'd use on a regular wall. DO they make specific windows for basements with block walls that don't have that piece or do I need to somehow just cut it off?

I checked all the websites for the normal Big Box stores and none of them seem to have that type except in Hopper style which we don't want. We prefer sliding or ones that open from the bottom.

Using the groove in the block to hold the window is a one-time only thing for the original windows. Likely you'll have to destroy the old frames to get them out. Then install replacement windows that are sized either for the existing masonry opening or a new RO created by installing a wood perimeter within the masonry opening.

You can probably find what you need at a big box store on a special order or go to a place like norandex.com .

Pressure treated wood is what I used at my abode. Not that it is considered wet but it does come in contact with concrete.


Popeye only reached for the Spinach can as a last resort...

If you don't need the ventilation you can fill it in with glass block. That will make it much more thermally friendly and still let in light.
