Does your lintel need replacing?

  • Share This Article

Sometimes it can be hard to know when you need to repair or replace parts of your property, so to avoid making needless renovations, it’s important you know what to look out for and the steps you can take.

What are lintels and why are they important?

Lintels support the doors and windows of a building and are typically made from steel. Because these openings are vulnerable parts of any structure, it’s imperative that the lintels are strong and in good condition to support walls effectively. Damaged lintels can cause larger structural issues that will escalate quickly if not remedied in good time.

What are the signs a lintel needs replacing?

Mortar cracks: If you’ve noticed cracks appearing in the corners of doors or windows, it’s likely your lintels need repairing or replacing. The cracks are usually in the highest corners rather than the lower ones and should never be brushed off as general wear and tear or a problem for the decorators to mask.

Line cracks in mortar: More serious deterioration can form cracks along your walls, not just limited to doors and windows. Stone or bricks may also have moved out of place, which means you need to take action as soon as possible.

What causes a lintel to deteriorate?

Like anything, lintels will eventually degrade on their own, but bad weather can cause them to be damaged more quickly. Cold and damp winters encourage corrosion, which is why it’s important to regularly inspect and maintain structures to avoid bigger problems surfacing. When corrosion occurs, the steel expands and puts a large amount of pressure on the surrounding walls. It’s this extra weight that causes cracks and displacement. Over time, the building will become unstable without this crucial support. Therefore, keeping on top of small issues can save you money as well as time in the long term.
