Cracking of Lime Mortar in newly erected wall

3 years ago

Hi All, we have a small extention being built, the walls were erected 2 weeks ago and they put a roof on it last week. I was inspecting the walls today and the external wall in brick seems ok but the internal wall in blocks has cracks showing in lime mortar ( a picture attached) which made me concerned. The foundations are extra deep because our neighbours have a tree (2.7m) so I do not think it is subsidance but it was very warm when the walls were erected so I perhaps it is linked to that? I do not know a lot about this but should I be worried and if yes, what should be addressing when talking to my builder? thank you for your thoughts, with best wishes, Marta

Hi there. Completely agree with everyone, you should paint the cupboards. I really like the colours in this picture as I think that the slightly 'greyer' off white cupboards would tie in well with your beautiful grey tiles. You wouldn't necessarily have to go so light on your worktop as in this picture. The laminate you showed in your third picture is really nice, where is it from? Currently doing my kitchen and trying to find a laminate that I like!

How to open up and old fireplace.....

Hi BFM, just looking at previous posts relating to opening up fireplaces and can't find anything that seems to mirror our current situation. Every fireplace in our new home (and there should be 6!) has been sealed with cement. There is no vent on the inside wall...in fact all there seems to be in the vicinity of where the fireplaces should be are plug sockets. I am absolutely desperate to start opening one up (I'd like to open them all up in time) just to see what they've done. Nothing seems to have been done "correctly" in the house so uncovering lots of mysteries. I'll post a photo example below.

Peeling paint, possible damp?

The plaster underneath the paint won't be dry otherwise this paint would not be bubbling like this. Don't cover it up with paneling as this could cause additional work later. If it were mine I would try to identify the source and see if it could be easily removed- you show just one area on your pictures, assuming other parts of the house are not affected concentrate on trying to identify the cause there as the solution may not be as expensive as replacing all the render- it could be that the garden level and soil are too high outside the window and need digging out, it may be that the window cill does not protrude enough and collected rainwater is running down this part of the house. It might be a faulty gutter and rainwater is washing down the house rather than being piped away, there could be a leaking pipe washing water down the outside, or there could be a blocked drain outside the window and therefore standing water, or the render could have been cracked and a repair could be inexpensive compared to full replacement. It might still be rising damp but check it's not something else first. Eventually you will have to have the plaster off inside and the wall injected and replastered and the skirting and floor replaced. You should check at that time the water hasn't rotted joists but until you can afford that you can regularly scrape of the paint and repaint with an oil based paint which will still likely cost less than the wood paneling.
