Lintel Repair & Replacement in Dorset
Failed lintels are a common source of structural cracking in Dorset properties. When lintels above windows and doors corrode, crack, or lose their bearing, the masonry above can drop — causing visible cracking and, if left untreated, serious structural problems.
Our lintel repair and replacement service covers all types including concrete, steel, stone, and timber lintels. We carry out targeted repairs where possible and full replacements where the lintel has failed beyond repair, always supporting the masonry above during works.
Many older properties in Dorset have lintels that have deteriorated over decades. Early identification and repair prevents the kind of progressive damage that can ultimately require major structural intervention.

Frequently Asked Questions
How do I know if a lintel has failed?
Signs include cracking above windows or doors (especially diagonal cracks from corners), sagging or dropping masonry above openings, and rust staining on brickwork near steel lintels. Any of these warrant a professional inspection.
Can a failed lintel cause subsidence?
A failed lintel itself doesn't cause subsidence, but it can cause similar symptoms. It's important to correctly diagnose the cause of cracking — our structural surveys distinguish between lintel failure, subsidence, and other causes.
How long does lintel replacement take?
A single lintel replacement typically takes one to two days. Multiple lintels may take longer. We install temporary support before removing the old lintel to prevent any movement.
What does lintel replacement cost?
Costs depend on the lintel type, size, and accessibility. We provide fixed-price quotes following a survey so you know exactly what to expect. The investment prevents far more costly structural damage.
Do you replace lintels in listed buildings?
Yes, we have experience working on listed buildings and period properties. We use appropriate materials and methods that satisfy conservation requirements. We can liaise with conservation officers on your behalf.
Can corroded steel lintels be repaired?
If corrosion is minor, it may be possible to treat and protect the existing lintel. However, if the steel has lost significant section or the masonry above has moved, replacement is usually the most reliable solution.
