    Re-bedding patio slabs

    I wanted to repoint my patio + fix some wobbly slabs. But it turned out a lot of them (23) were actually wobbly and after taking them out, I'm kind of stuck what to actually do.

    Separated and Eroded Mortar: Concerning, or just in need of some repointing / TLC?

    Hi all, first post here after a bunch of research and probably going a bit stir crazy. We're scoping out some projects for our 1970s mid-terrace townhouse, which had me looking at the walls. I've noticed a few issues, which I'm hoping are just normal ageing for a near 50 year old house and...
