Crack Stitching & Structural Repairs
Cracks in brick or stonework are more than just cosmetic — they can indicate movement, weakened mortar beds, or long‑term structural stress. At S.J. Lewis Repointing Services, we provide expert crack stitching and structural repairs across Oxfordshire, restoring stability, preventing further damage, and protecting both modern and heritage buildings. Our repairs are discreet, durable, and designed to blend seamlessly with the original masonry.
🧱 Professional Crack Stitching for Brick & Stone Walls
Crack stitching is one of the most effective ways to stabilise cracked masonry.
We install high‑grade stainless‑steel helical bars into the mortar joints, bonding them with specialist grouts to reinforce the wall and redistribute structural loads.
Our crack stitching repairs are ideal for:
- Vertical and stepped cracks
- Movement‑related cracking
- Failed mortar joints
- Historic brick or stone walls
- Chimneys, gable ends, and boundary walls
This method provides long‑term strength without altering the appearance of the building.
🛠️ Sensitive Repairs for Heritage & Listed Buildings
Historic buildings require a careful, conservation‑led approach.
We combine modern crack stitching technology with traditional materials — such as lime mortar — to ensure repairs remain breathable, flexible, and fully compatible with the original structure.
Our heritage‑appropriate repairs:
- Stabilise cracked stone or brickwork
- Prevent further movement or separation
- Maintain the building’s historic integrity
- Blend seamlessly with original materials
Every repair is carried out with precision and respect for the building’s age and character.
