Replace Basement Window Cinder Blocks

Basement window cinder blocks are an essential part of any basement wall, providing structural support and allowing for natural light and ventilation. However, over time, these cinder blocks can become damaged or deteriorate, compromising the integrity of the wall and the comfort of your basement. Replacing basement window cinder blocks is a relatively simple task that can be completed in a few hours with the right tools and materials.

To begin, you will need to gather the following materials:

New cinder blocks
Mortar
Concrete adhesive
Hammer
Chisel
Level
Safety glasses
Gloves

Once you have gathered your materials, you can begin by removing the old cinder blocks. To do this, use a hammer and chisel to break the mortar around the blocks. Be careful not to damage the surrounding wall. Once the mortar is removed, you can carefully pry the blocks out of place.

Next, you will need to prepare the new cinder blocks. Apply a thin layer of concrete adhesive to the bottom and sides of the new blocks. This will help to create a strong bond between the blocks and the wall.

Now, you can begin to install the new cinder blocks. Place the first block in the bottom corner of the window opening. Use a level to ensure that the block is level. Once the first block is in place, you can continue to add blocks, working your way up to the top of the window opening. Make sure to apply concrete adhesive to each block before placing it in position.

Once all of the cinder blocks are in place, you will need to fill in the gaps between the blocks with mortar. Use a trowel to apply the mortar, and then smooth it out with a sponge.

Finally, you will need to allow the mortar to dry completely. This will typically take 24 to 48 hours. Once the mortar is dry, your new basement window cinder blocks will be complete!
