Can I ask what a projecting nib is just to clarify? If it means some of the concrete which forms part of the lintel sticks out/protrudes from the wall somewhat then yes this is the case. Probably an inch or more sticks out and from the underside where the lintel is good and not been touched...

It must be more than just the nosing nib if the steel bar has been cut surely?

Out of interest what were you cutting them for?

Saw this.... Could helical bars fitted above guarantee the integrity even if this lintel was to begin to fail in the future?

Thanks. Yes there is an element of homebuyers panic as we had to walk away from a previous purchase of an identical house nearby where they'd knocked down an exterior wall all the way along the back for an extension and surveyor couldn't identify what was then holding the back of the house up...

30 years at the very least we suspect, as there was real linoleum fitted to the conservatory floor.

To add having read further info on these forums I suspect this concrete lintel is unlikely to be pre-stressed. Therefore could it be worth welding a piece of new rebar in to bridge the gap before building the shape of the lintel back up? Does anyone know the potential price for a structural...

I thinks that's the way the builder sees it. Basically the windows ideally should have had lintels fitted above to begin with. This has simply been corrected. I do think the double glazing installers are only likely to fit and certify windows only if they find the holes to be adequate. I.e. if...

I presume they are something like this although I'm not a builder and just employed one: https://www.wickes.co.uk/IG-Ltd-Angle-Section-Lintel-L10-1500mm/p/153209?gad_source=1&gclid=Cj0KCQiA6vaqBhCbARIsACF9M6mssSRFZM8lYGqUcAGZ44x1qkA5nEJV-zrY0mgcqKyX-jrC8SFE-tkaApWEEALw_wcB&gclsrc=aw.ds Where...

Refurbishing our 1960s semi. There were 5 small windows situated on the gable wall approx only 500mm wide which presumably used to have timber frames and since having uPVC frames were identified on survey as potentially requiring adequate lintels above. Our builder has fitted an L shaped...

Thanks. Out of interest what years were the asbestos years? I'm not sure whether the ceilings have been replaced since the 60s but apart from a few light cracks where different boards are joined underneath the ceilings look pretty good so may well have been re-done in the 90s when I suspect...

Would treating the rust and then welding a a piece of galvanised steel to span the gap help with the structural integrity? Or would this be pointless if the existing steel was pre-stressed? Could there be any other remedy such as having a few rows of bricks removed from above the lintel where...

Thanks for that. Is it at all possible it could contain asbestos or is this highly unlikely and we can proceed without worry?

Hi all. We are doing up our first home which was built in the 1960s. After removing the gyproc coving from the living room ceiling I have found a few holes in the plaster where there seems to be some sort of brown fibrous material behind, which looks to be part of or weaved within the plaster...

Hi all. Brand new poster here. We are doing up our first home and removed an old conservatory a few weeks ago which spanned most of the width of the rear of the house. The house was built in the early 60s. You will see there is what looks like either a pre-stressed or reinforced concrete...
