I'm trying to work out these rectangular bits are between bricks at various places around my house. There are a couple visible around windows (possibly due to mortar falling off around it?) but there's also one visible on the edge of the wall that the garage door sits inside.
Either way, they're all very lose and could be pulled out with no effort. They look like wood but feel extremely light and have lots of tiny holes in them.
I'm mostly asking out of curiosity but also thinking I should be taking the ones by the windows out and sealing the gaps to prevent water getting in?
