Sealing the gap between the walls and the floor in the storage closet has been on the to do list for some time. I emptied the closet and vacuumed the floor to access the gap on the outside walls.
The closet floor is part of the original slab. When the tile was removed from the floor we intended to break out this concrete. But since the block wall is sitting on it and we didn’t want to tear that down we kept the existing slab in the closet. The floor is quite rough from removing the quarry tile. Eventually I will knock out the lumpy cement and lay tile.
With the floor cleared out and cleaned I used spray foam to seal the gap.
Then everything went back into the closet and I also moved three of the big wooden doors into the closet. I had to get them out of the way to get shelves and poles in the master closet.
