Traditional methods are to remove the lintel and rebuild it, this is an intrusive method of repair and a slow process typically taking around a day to properly remove and replace a lintel. Yes i appreciate that most of the cost is going to be the faff, props, removal of the window temporarily and the cracked lintel, etc rather than the replacement lintel itself. Cracks Above Window and Door Openings. Diagonal cracks above window openings and door openings are common structural defects that show signs of movement which will need to be rectified. Diagonal Cracking Above Opening. Diagonal stepped cracking often indicates that the lintel that supports the masonry above the opening has failed. Replace the lintel. Do not repair it. Lintel are very cheap to buy. They start from 10 quid for small ones. I doubt yours will be more than 100 quid. Get some gorm. Glad you like it! Concrete lintels will happily stay in place even if cracked. The main problem is not a structural issue, but rather water penetration to the crack, causing the.

- After moving into our new house a few weeks ago, l have noticed a vertical crack through the sandstone lintel above our basement kitchen window. The crack is around 1/3rd across the stone, and has been filled with a clear silicone by the previous occupants to prevent water ingress (l guess). The window below it opens fine, and there are no other signs of cracking, bowing walls, cracked pointing or stone etc. The walls are sandstone (irregular sized stones), around 1.5 feet thick throughout. The house was renovated around 12 years ago, although built in the late 1800’s.We had a structural surveyor do a report on the house before we bought it (RICS approved), however it was not picked up on. Do l have any comeback on this. Alternatively, what are my options?Posted 6 years agonormal practice is, I think, to glue a piece of glass across the crack and see if it shatters.If it doesn’t it’s old movement.If it were me I’d just monitor it for a bit and see if it changes.Posted 6 years agoYou *could* ask Building control to look at it. In my experience they are very helpful. Even if they say it needs replacing, it’s not a huge job, some Acrow props to take the weight, chisel the old one out, slide in a new one and repack with mortar.Posted 6 years agoYou’d expect this to be spotted by a surveyor, tho I dunno if it’s covered by a structural survey (again, you’d think so!)Posted 6 years agoCertainly worth contacting the surveyor for his answers etc . but not a massive job to replacePosted 6 years agoCan you clarify that? Do you mean it’s 1/3 of the way from one side of the window from the other, or it goes from the bottom of the lintel to 1/3 the way up (or even from the outside to 1/3 of the way in)?Where it is along the length, how far through and whether it’s parallel sided, tapered, etc, are all important in working out how structurally significant it is.Posted 6 years agoUnlikely to be a major problem. I see a lot of “damaged” houses and cracked stone lintels are quite common. They don’t often reflect a serious structural problem. If the on the inner face of the window opening spanned by the lintel is sound, it would indicate no movement has occurred since the room was decorated. Glass tell-tales are very old skool and if one was fitted it would be likely to crack just due to thermal movements, which would not necessarily indicate a problem. Lintels don’t usually carry a huge amount of weight. If you project a 45 degree line upward and toward the window centre from either side of the opening, it’s only the weight inside the triangle that’s actually supported by the lintel.Get a structural engineer to have a look if you’re worried, but I wouldn’t lose a lot of sleep unless you see signs of progressive movement, which will be evident in the form of cracks in the stonework immediately above the lintel itself (in, or at the edges of teh imaginary triange described above).

Nothing collapsed in the 12 years it was like that and it can always be fixed even if it does need replacing. And if it does I’d be looking for at least a refund if you payed for a strutural survey.Posted 6 years agoDifficult to say without seeing a picture, but you could probably use a Helifix repair – chase a groove through the lintel, insert stainless steel bar and fill with colour matched mortar / resin. You can also run Helifix bars through the stonework above, effectively making the stone into an additional lintel.Posted 6 years agoI’d hazard a pretty educated guess it’s going no where!Posted 6 years agoI’d not worry too much – the silicon is probably there to keep the water out and if it is moving there’ll be plenty of evidence of it.Posted 6 years ago
