Lintel and Mullion Repairs to Restore Strength and Character
Our experienced craftsmen improve safety and structural integrity by carefully repairing or replacing lintels and mullions.
We identify the cause of damage or failures, both internally and externally.
Understanding the historic construction techniques often used for these features and the compatible materials and methods required for remedial works, we restore load-bearing strength without compromising the building’s character or appearance.
Our specialists deliver works to overcome:
- Structural movement
- Cracking or bearing failure
- Timber decay
- Stone deterioration
- Water ingress
- Eroded decorative elements
- Inappropriate or unsympathetic repairs
Window and Timber Restoration
As highly skilled craftsman, we also restore and enhance timber frames and features, preserving the history and charm of older buildings.
We carefully remove and replace decayed elements, repair areas using wood splices or resin solutions, upgrade glazing units and hardware as needed, and use modern solutions to draught proof and improve functionality and durability.

Frequently Asked Questions
We start by identifying signs of failure, such as cracking, sagging, or displacement. From there, we assess the load, materials, and any historic construction techniques to decide whether a repair, reinforcement, or full replacement is the most appropriate solution.
Yes. Wherever possible, we use methods like piecing-in, stone consolidation, stitching, or plastic stone repairs to stabilise and restore original features without removing them. This is especially important for preserving historic fabric.
Absolutely. We follow conservation guidelines and use compatible materials and techniques to ensure that repairs maintain the building’s character while meeting structural and safety requirements.
We can expose the structure for inspection and, if needed, install hidden reinforcements or load transfer systems to support the facade while discreetly strengthening the structure behind the scenes.
Yes — but only when appropriate. We often integrate sustainable, non-visible materials like resins, reinforcement bars, or breathable grouts that enhance durability without compromising the building’s original appearance.
Yes. We restore timber frames and lintels using splicing, resin repairs, and like-for-like replacements. We also upgrade glazing, improve draughtproofing, and preserve architectural detail wherever possible.
We don’t just repair — we also address the root cause. Whether it’s water ingress, settlement, or poor previous work, we include moisture control, proper load distribution, and maintenance advice to prevent recurring damage.
Not necessarily. Minor cracks can often be repaired using stitching or reinforcement techniques. Replacement is only necessary when the structural integrity is severely compromised or the damage is beyond restoration.
