Rotten timber lintel
What we found: The timber lintel above one window had decayed to the point of effectively breaking, leaving a clear sag in the brickwork it was meant to support.
What's causing it: Timber decay starts from the inside and often gives no visible warning until the structure is already compromised — a sagging window line generally means the wood has already lost most of its load-bearing strength, whatever it looks like from outside.
What we did: We replaced the rotten timber lintel with a modern concrete lintel, removing the decayed timber entirely and making good the surrounding brickwork. Completed over 2 days.
Why lintels fail across Dorset
Dorset's coastal exposure speeds up corrosion in steel and concrete lintels, while the county's older housing stock means rotten timber lintels are also a regular find — timber rots from the inside out, often invisibly until the damage is significant.
Replacing a timber lintel with a modern concrete one removes the risk of the same decay recurring, and we make good the surrounding brickwork to match the original property.
Lintel replacement cost in Dorset
Most Dorset lintel jobs start from £800, with the final cost shaped by the lintel material, how badly it's decayed or damaged, and how easy the site is to get to. Here's what actually moves the price:
- Extent of decay — timber lintels that have rotted significantly may need more surrounding brickwork made good
- Lintel type — replacing timber with concrete is generally more involved than a straightforward steel-for-steel swap
- Making good — matching render or pointing to the surrounding period property can add time
- Access — ground-level openings are straightforward; upper floors may need scaffolding

Common questions
Do you cover all of Dorset, or just Bournemouth?
We cover the whole county, including Poole and Christchurch, not just Bournemouth itself.
How much does lintel replacement cost in Dorset?
Starting prices are usually around £800, increasing with the lintel material, how badly it's decayed or damaged, and how accessible the property is. We'll give you a fixed price once we've actually seen it.
Why is timber lintel decay common in Dorset properties?
Dorset has a significant amount of older housing stock built before concrete and steel lintels became standard. Timber rots from the inside out, often invisibly until the damage is significant, which is why period properties are a common place to find this issue.
Noticed a problem like this?
Dorset's older housing stock and coastal exposure mean we see the full range of lintel problems across the county, from corrosion in steel and concrete to genuine timber decay in period properties. With over 30 years of experience, we diagnose the real cause and recommend repair or replacement honestly, never the more expensive option by default.
