Moggaman Posted May 29, 2023 Author Share Posted May 29, 2023 Block.. this one is on edge with precast slab on it . The chase for wires is roughly speaking running up there also Link to comment Share on other sites More sharing options...
nod Posted May 29, 2023 Share Posted May 29, 2023 It could be settlement or shrinkage Easy enough to repair Link to comment Share on other sites More sharing options...
Moggaman Posted May 29, 2023 Author Share Posted May 29, 2023 I am getting very paranoid worried about this as I have a lot of this around the house. The cracks in the photo are new. I’m in the house 10 months. Other cracks upstairs are there 6 months and extending ? Both cracks shown below are same size… no cracks are wider than 1mm. Appreciate ur input… Link to comment Share on other sites More sharing options...
Nickfromwales Posted May 29, 2023 Share Posted May 29, 2023 I think you'll need to reassess after 12 months of 'settlement'. The build was done during the "wet" season I assume, and the fabric of the build heavily soaked and then all of that moisture got locked in by the render. The different rates at which all this would dry out would be significant, so I would fill these cracks with a good quality paint and monitor every 3 months. Staring at this every day will put you in an early grave, so, relax, as the house isn't going to fall over any time soon, and monitor as above. Tapping on the mortar will reveal if it is going 'hollow' (has separated from the structure) which would be more of an issue. Answers for this problem will not be coming any time soon, well not ones worth hearing at this time anyways. Time will tell, I'm afraid. In the meantime, go about your daily business and stop staring at these cracks is my honest advice. Link to comment Share on other sites More sharing options...

I do have one hollow section upstairs on a non load bearing wall. Hollow section is about 300mm x 300mm. What drives me bananas is moderate to loud bangs/ thumps I hear most nights from what I perceive to be the wall upstairs. Makes me think something is giving !

If it's daily, then it's probably more closely attributed to heat / cool of the roof structure. I very much doubt your masonry walls are on the move! 1 Link to comment Share on other sites More sharing options...
saveasteading Posted May 29, 2023 Share Posted May 29, 2023 All good advice. Houses move. I would send a polite note to the contractor though, putting it on the record and asking what their proposal is. 3 Link to comment Share on other sites More sharing options...
TonyT Posted May 29, 2023 Share Posted May 29, 2023 Plus 1 for waiting that’s why years ago you were advised not to decorate and live with the contract magnolia for a year to let the building settle and dry out. Link to comment Share on other sites More sharing options...
TonyT Posted May 29, 2023 Share Posted May 29, 2023 Of course interior designers would now call it something arsey like stone instead of magnolia 1 1 Link to comment Share on other sites More sharing options...

SteamyTea Posted May 29, 2023 Share Posted May 29, 2023 Is the thumping caused by a lady from Ealing. Maybe she don't have too many feelings. If she laid on her back, observed the crack. She might fix it by sealing. Link to comment Share on other sites More sharing options...

I have no idea, just the only thing I ever hear that's reported as doing what you are hearing / experiencing has been the roof. Mainly SIP's roof and with metal standing seam. That's the only bit of the house that heats up and cools down (expands & contracts) quickly enough to generate noise. Do you have tiles / slates / metals?

Probably be worse while we have some sunshine, and almost disappear during winter. May settle, as new houses do tend to do these things. Link to comment Share on other sites More sharing options...
Dave Jones Posted May 30, 2023 Share Posted May 30, 2023 minor drying out, completely normal. Was the house built to your design or just bought it ? Link to comment Share on other sites More sharing options...
