Why Choose Our Specialists?
When it comes to structures like lintels, experience matters. At LSR, our qualified specialists use modern repair techniques to restore damaged or failing lintels—saving you the cost and disruption of full replacements. We work with both historic and modern properties and use materials and methods designed to blend seamlessly with your existing structure.
Signs Your Lintels May Need Attention
Not sure if your lintels are still doing their job? Common signs of lintel failure include:
- Cracks above or below windows and doors (often forming a triangle shape)
- Dropping or sagging in brick arches
- Displacement or bulging around window openings
- Visible corrosion in metal lintels
- Timber lintels showing signs of rot or insect damage
- Structural cracks after window replacements
In some older properties, brickwork may rely on timber-framed windows for support. When those are replaced with modern UPVC frames without installing a new lintel, the surrounding wall can begin to fail.

Repairs and Restoration Services
We repair a wide range of lintel types using advanced techniques and high-quality materials:
- Timber Lintel Repairs: Addressing decay, sagging, and brickwork movement
- Masonry & Concrete Lintels: Crack stitching, reinforcement, and corrosion protection
- Steel Lintels: Surface preparation, treatment, and structural reinforcement
- Arch Restoration: Stabilising historic brick arches and correcting displacement
- Load-Bearing Support Installation: Adding support where lintels are missing or compromised
Each repair is designed to be sympathetic to the building’s structure and finish, preserving its appearance and integrity.
Why is Routine Maintenance Important?
Lintels are vital load-bearing components. Over time, exposure to moisture and weather can weaken timber, steel, and concrete lintels. Mild steel reinforcement within concrete, for instance, can corrode and expand—leading to cracking, deflection, and spalling.
Routine maintenance can significantly extend the life of your lintels:
- Inspect regularly for signs of cracking, corrosion, or sagging
- Keep mortar joints in good condition, especially around brick arches
- Ensure protective coatings are intact
- Act early to avoid expensive structural issues later
