Lintel Repair

Do I Need a Structural Engineer to Replace a Lintel?

31 March 2023

A lintel isn’t something that everyone takes notice of every single day. In fact, most people go through the week without even noticing the lintels above their doors and windows.

However, once that lintel starts to fail, that’s when it’s going to be front and centre of your attention. Lintel failure can lead to all kinds of different property care issues including damp, timber failure, and even structural issues like cracks in your wall or sagging masonry.

So, if you are concerned that your lintels might need some attention, what can you do to have your lintel repaired – and why is it vital that those repairs are carried out by a professional?

What is Lintel Failure?

If you have read this far and are a little confused about what might constitute lintel failure, lets quickly run through what it is and what it might mean for your property before addressing the repair process.

A lintel is the beam found above doorways and windows, taking the weight of the wall above and displacing it across its length so that the cavity in question is not warped by the weight of the building above.

Basically, it’s a load bearing beam that ensures your doorways and windows stay in the shape that they need to.

Your lintel failing means that your window might start bowing, or that your doorway could warp, making it difficult for the door to close, or easier for drafts to make their way through your windows. In any case, it won’t be long until these small issues, like a draught, turn into something much worse.

Damp, dry rot, woodworm, cracks in your properties walls, bowed cavities – they are all probable in the event of lintel failure, and the sooner that you spot the signs of a failed lintel, the sooner you can take action, and avoid drastic consequences of lintel failure.

Why Should You Avoid Repairing a Lintel Yourself?

When it comes to lintel repair you are always better off contacting an expert rather than tackling the problem yourself – unless of course you are qualified when it comes to structural repair.

Essentially what you are dealing with when it comes to lintel repair or replacement is the entire weight and integrity of the wall around the cavity, balancing on your work.

If the replacement of the beam goes wrong, then you could see your wall bow, collapse, or just warp in a way that drastically effects the integrity of your property. That’s only an immediate effect as well, the result of a bad job going wrong at the time – but its far from the only possibility.

If you were to use the wrong timber or material for your lintel for example, what are the chances that it holds up on installation – but slowly bows over time, as it isn’t able to take the weight? Realistically, it’s a very likely outcome, and if you don’t understand exactly how to best replace or repair a lintel then you may well just be kicking the can down the road.

That’s not to mention issues when it comes to timber repair. If you aren’t a trained timber specialist then what you might perceive as a ruined piece of timber could well be salvageable with the right skills. The inverse is also true – you might believe that a bit of wood glue and replacement timber can strengthen your lintel out, when really woodworm may well be active deep within the timber, and your lintel will remain at risk despite your intervention.

Realistically, you need a property care specialist to not only inspect your lintel, but carry out the repairs as well so you can rest safe in the knowledge that your lintel repair will last.
