I need to install a window in my basement. I will need to cut a hole in the foundation to do so because there has never been a window there. What tools do I need and is there a book or website that has instructions to follow?

You will need to rent a diamond saw to cut the foundation wall, or check in the phone book under concrere cutting and hire it out.

To make a hole in a foundation wall made of concrete block and/or brick, do the following:

Using this method you will end up with a nice neat job where the block and/or brick opening will be flat inside the opening an will look better and work better. It also make fastening the window in place much easier as well as more secure.
1. Using a 2 lb. Hammer and cold chisel break out the blocks and/or bricks to make a hole slightly larger than the window opening you need. (Be sure to remove the whole blocks and/or bricks. Do not leave any partial pieces.)
2. Re-lay the concrete blocks (cut as needed) to fill in the whole to the exact size needed + 3/8” for caulking and easy placement of the window. If a brick veneer is used do not lay it back yet. A steel lintel or bond beam may be needed to secure any block or brick that cross over the window. (If no blocks cross over the window opening you can skip the following steps.)
· A bond beam is the preferred way for supporting block over a window. To make a bond beam 2 additional courses of block will have to be removed above the window
· A temporary support will be needed to hold the blocks at the correct height for the top of the window
· Place the bond beam blocks, using mortar between them, on the temporary support across the opening
· Fill the bond beam blocks with concrete and at least 2 - #4 rebars
· Lay the remaining course to fill in the rest of the opening above the window
· Wait a minimum of 24 hours and remove the temporary supports.
3. Set the window and fasten in place.
4. If a brick veneer is used you will lay it now. Lay the brick to within 1/4” of the brick molding on the window. This is to allow for expansion and contraction as well as a space for caulking.
5. Caulk around the window.
6. Trim out the interior if desired.
