Structural Crack Repairs in Kent
Crack stitching for brick and stone, repaired and repointed to blend in.
Structural cracks and damage are common in older homes. At Prestige Brickwork, we repair cracks in brick and stone, tying the masonry back together and repointing so the repair blends in with the original brickwork.
Common causes of structural cracks
- Thermal movement
- Cement pointing used on buildings originally built with lime mortar
- Natural settling of the house
- High-stress areas, such as below windows and above doorways
- Masonry disrupted by window or door replacements
- Inadequate or failed load-bearing lintels
If a failed lintel is the cause, see our lintel replacement page.
How we repair structural cracks
- We cut into the mortar bed with a specialist Arbortech mortar saw, to at least half a brick’s thickness.
- We create slots extending 50 cm either side of the crack, spaced every 4 to 6 courses depending on the needs of the structure.
- We inject cementitious grout or polyester/epoxy resin into the slots, then place a helical bar reinforcement.
- We apply another layer of grout or resin to secure the bar.
- Finally, we repoint the area with colour-matched mortar, so the repair blends with the original brickwork.
