Restoration & Refurbishment Question
Cracks keep appearing
I bought a 1930 semi detached house last year and had it fully refurbished. All plaster was removed, new windows, floors, roof - the works. The inside was plastered with plasterboard and I was told by my builder that cracks will appear when the plaster dries out. A year later I do have a number of crack in the walls most of them vertical mainly above doors. These cracks appeared over time which I was assured was shrinkage and quite normal. However there is a big crack on the bathroom door running all the way along the door frame (not above the door frame) and this crack seems to get bigger. Especially since I did some groundworks outside I have noticed it is expanding and I keep hearing loud cracking noises now and then in the house. I am getting a bit worried now and have stopped my groundworks outside for the time being. My builder came back to look at the crack and instantly put it down to shrinkage. I don't know - is it possible that it is still shrinkage after a year me living there? As I said the crack appeared at the beginning but since has gotten bigger and is now 3-4mm. So no hairline crack anymore.
Any advice what my best next move should be?
Firstly what type of ground works are you doing outside?
A crack of over 1-1.5 mm is not classed as shrinkage in a property of your age, it is classed as a movement crack.
As your re works have been by the sound of it invasive, there will be some resettling especially as the roof sounds to have been removed?
It needs to be checked out Asap.
