At the house, There is a single storey extension, when i moved in whilst a roofer/buildeer was replacing a tile i asked him to look at a crack which followed the pointing front the corner of the patio door upwards, also a smaller one from the other top corner. Also a crack in one corner on the inside this was filled and hasn't cracked since

He chased the pointing out and re did it for me. But i have noticed the crack has come back following the same line or there about

How do i go about finding out whether it was done right, or there is movement maybe due to the lintel above the door or even worse subsidence Has anybody had similar or in the game to pass on a opinion

I think you can rule out subsidence
Nearly every house has 'stress' points like that at lintels and window edges. I would say it is 'settlement' cracks and the pointing may not have been deep enough.

Agree with CG so brace yourself for a NATO airstrike and minor cracking then the least of your worries.

Seriously, it doesn't seem too much to worry about. From your photo it seems that this wall is a single story extension with a lean to roof. The roof will press down and out on the rear wall if the rafters are not supported along their length adequately enough and you often then get cracking over a side window. Agree that the pointing might not have been deep enough or too strong a mortar mix used with too high a cement content and so there has been some shrinkage. I would also check the underside of the roof framework to make sure the rafters are adequately supported to prevent outward pressure on the rear wall resulting in the cracking you have seen.

These comments made without prejudice ie don't think about suing.

Cool looks like one less thing to sort by the sounds of it,

I years to come I am planning on building on top too an extending the rear so things like footing can be inspected then and most likely underpinned Former Mod/Member, with the most post & Chicken George Arch nemesis

I understood it all, i suppose the fact the extension has been up since 1990 something, should rule a lot out

I want some of the original house pointing looking at, and all i hear is its a long and boring job grinding the old and then adding the new and nobody wants to do it, but i'll keep looking, i don't know if a full repoint is a DIY job  Former Mod/Member, with the most post & Chicken George Arch nemesis

A DIY pointing job would look like a CRV/Rav4/Sorrento/Outlander/Forester etc ie s**t.

House was built in 70's, this door is in an extention built in the 90's, I can see a galvanised lintel above this opening which looks to have been in since the extention was done (it does not look like it's been cut out) Former Mod/Member, with the most post & Chicken George Arch nemesis

If you think it is slowly getting worse you could pop down to your local builders merchant and pick up a couple of glass 'telltales', stick them over the mortar joints and see if they break. Doesn't look too bad from the photo, generally a common situation. Could be slight settlement although any settlement should have stopped within a few years of construction. If your house is built on a clay soil you may get intermittent shrinkage and 'heave' due to changes in moisture content. Suggest you just watch for any water ingress at the pointing if the wall is on a weether face.

I'm keeing my eyes on it, and may get a builder in to have his opinion on it and some other work Former Mod/Member, with the most post & Chicken George Arch nemesis
