To DIY or not - tiling front garden path
There is a spot on the tiled walkway to my front door that has become a bit sunken, the tiles are starting to pop out of place. I had the mistaken idea that I could easily fix it by putting down some kiln-dried sand and laying the tiles back in their original spots once it was level - I can’t even bear to put up the “after” photos, it has not worked at all, they’re even more disjointed now. I should have seen that coming. It seems there is not a solid base beneath the whole path, the part that is sunken borders the edge of where a concrete base ends and the rest is clay I think.
My question is, how hard of a project is this to tackle on my own? I’ve never laid tile before. I have a good bit of time this summer and the B&Q is just down the road. I have a can-do attitude and very little practical experience that gets me in trouble with home projects at least as often as it gets a result. Am I going to wish I paid a pro to fix this, or is this a reasonable thing to try and do myself? I’d be grateful for advice and any recommendations you all have.
