Exclamation Odd size block situation

Hello!

I want to close up a basement window in our cinderblock foundation. I'm trying to not rent a concrete saw if possible. The height of the opening in the basement wall is 19". I haven't taken the window out yet to see if they built up the blocks an inch with concrete to reduce a 20" opening to 19" for the window (it's parged over), but it doesn't seem like it.

What is my best option for closing the 19"? I want to stick with concrete blocks and not bricks or anything else. How do I get to 19 inches when blocks are 8" or 4" tall?

Thanks guys!

Concrete blocks are pretty easy to 'cut' with a brickset or cold chisel and hammer. It'll take longer than with a saw, but for 2-3 blocks, it's not worth renting a saw or angle grinder.

Yeah - I have a cold chisel, but was hoping to avoid that. Any idea how they would have the existing wall blocks such an odd size? Can't be a block combination right?

two 8" tall blocks capped with a 4" cap block might get you there .... or thinner cap block with wider joints.

@marksr - I can't find anything thinner than 4". Is there anything?

1.5" caps are pretty common, you can also get 2"
If they don't have them at your local big box, check with a block supplier. I live near a small town and there are 3 with in driving distance.
