Perhaps not my DIY disaster but generally a disaster.
About two months ago I removed the old partly rotten wooden decking behind the house, one board was lying right under the threshold of my patio doors. Two weeks ago I removed a particularly stubborn plank that was screwed to the wall under the threshold and broke a few tiles under the doors in the process, mostly because the wall behind those tiles seem to be just crumbling off by itself. I did not notice the tiles falling out all together as they do now on the photo.
Today I'm having a new deck installed and one of the guys casually mentioned that my patio door are shifting, the WHOLE thing with the frame just shifting down the wall. You can see the huge crack in the sealant on one side and some of the top of the frame bending as the doors are sagging. What the sheer heck is that? The house is about 60 years old but there are no signs of it moving anywhere - no cracks or other problems. But a lot of things in this house from that old decking to indoor electrics seem to be DIYed and a bit wonky but I don't know if that would apply to the patio doors.
I suspect that the whole patio door was propped up by the old decking and maybe even the tiles provided some minor support (because I did not notice the sagging until I broke some of the tiles but I might be wrong) - is it normal for patio doors to rest on the decking like that? If not, could it mean that there is something wrong with the wall under the patio doors? My biggest concern is masonry rot but I'm not sure how to identify it for certain
And lastly, could this be fixed by propping up the frame somehow (and how to do it?) and installing new decking? My new decking will be composite so a lot more rot-proof.
Any ideas/past experiences are much appreciated!
