Lintel Replacement Cost (2026 UK Guide)
Lintel replacement costs in the UK typically range from £800 to £3,500, depending on the lintel type, the width of the opening, and whether the wall is load-bearing. Replacing a lintel is often required when cracks appear above doors or windows, and while many cases are straightforward, structural or external walls can significantly increase costs.
This guide explains average lintel replacement costs in 2026, what causes lintel failure, how to spot the warning signs, and when professional structural repairs are required.

What Causes Lintel Failure?
- Corrosion of older steel lintels
- Inadequate original lintel size
- Water ingress causing rust expansion
- Poor workmanship during installation
- Structural movement or subsidence
- Age-related material fatigue
Signs You Need Lintel Replacement
- Cracks forming above doors or windows
- Stepped cracks in brickwork
- Windows or doors becoming difficult to open
- Visible rust staining on brickwork
- Sagging brickwork above openings
- Cracks that reappear after repair
What Affects Lintel Replacement Costs?
Wall Type
Replacing lintels in external or load-bearing walls is more expensive due to structural support requirements.
Opening Width
Wider doors or windows require heavier lintels and more labour.
Lintel Material
Steel lintels generally cost more than concrete but are required for most external openings.
Access & Making Good
Scaffolding, brickwork repairs, and internal plastering add to overall cost.
Structural Surveys
Structural engineer input may be required for load-bearing walls or larger openings.
Lintel Repair vs Replacement
Repair is suitable when:
- Cracking is cosmetic
- Lintel corrosion is minimal
- Structural support remains adequate
Replacement may be better when:
- Lintel is rusting or failing
- Brickwork is sagging
- Cracks continue to worsen
- The opening is load-bearing
When Is Lintel Failure an Emergency?
Lintel problems should be treated as urgent when:
- Cracks above openings widen rapidly
- Brickwork appears loose or unstable
- Doors or windows suddenly misalign
- Failure follows subsidence or flooding
- There is a risk of brickwork collapse
For urgent pricing, see our emergency builder call-out cost guide.
Can You Replace a Lintel Yourself?
DIY checks (safe):
- Visual inspection of cracks
- Monitor crack progression
- Check for rust staining above openings
Professional repairs recommended for:
- All lintel replacements
- Load-bearing walls
- External brickwork support
- Structural alterations
Lintel replacement is a structural task and should not be attempted DIY.
How Long Does Lintel Replacement Take?
- Single lintel replacement: 1 day
- External wall lintel: 1–2 days
- Wide openings: 2–3 days
- Making good & plastering: 1–2 additional days
Timescales vary depending on access and wall type.
Does Home Insurance Cover Lintel Replacement?
Home insurance may cover lintel replacement if failure results from a sudden insured event, such as subsidence or storm damage. Damage caused by corrosion, wear and tear, or poor installation is usually excluded.
Always check policy wording before starting work.
How to Reduce Lintel Replacement Costs
- Address cracks early
- Fix water ingress promptly
- Avoid repeated cosmetic repairs
- Combine lintel replacement with window upgrades
- Arrange professional inspections early

Final Thoughts
Lintel failure is a common cause of cracking above doors and windows and should not be ignored. Early replacement prevents further structural damage and avoids much higher repair costs later.
