Structural Crack Repairs

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

  1. We cut into the mortar bed with a specialist Arbortech mortar saw, to at least half a brick’s thickness.
  2. We create slots extending 50 cm either side of the crack, spaced every 4 to 6 courses depending on the needs of the structure.
  3. We inject cementitious grout or polyester/epoxy resin into the slots, then place a helical bar reinforcement.
  4. We apply another layer of grout or resin to secure the bar.
  5. Finally, we repoint the area with colour-matched mortar, so the repair blends with the original brickwork.

Recent project: chimney stack in Margate

Cracks in this chimney stack in Margate were stitched with stainless steel helical bar and resin, then pointed with traditional lime mortar.

From the time I contacted Sam this company have been exemplary. Harrison came promptly to survey the work necessary and explained everything to me. The quote came through promptly and Sam was available to answer a few things I was unsure about. Ben and Bailey arrived on time to do the remedial work needed above a window and explained and showed me photos of all stages of their work. George, Tim, Tom and Olly arrived promptly everyday to rake out and repoint the whole gable end of the house. Throughout the week the whole team were polite, kind and extremely hardworking. They left the site clean and tidy each day and did a really thorough clean on the last day. I would like to thank them all and would highly recommend this company to friends and family.

Sam and his team are brilliant, we had all 3 side of our house repointed as well our fireplace, some damaged bricks were replaced and crack stitching also done. communication was quick and easy at all times. We were often at work but were more than happy to leave a key for them. They were always polite and cleaned up at the end of the day. They’re a family business and they know their stuff when it comes to lime repointing and brick work. We’ve had lot of complements about the work. Wouldn’t hesitate to use them again.

I had Sam and his team down to repoint my wall.   This is a small family business, the guys are very polite, professional and considerate.   The work is done to a very high standard, they came on time and cleaned up behind them.    I can highly recommend Prestige Brickwork.  It is good to see a lovely group of young men working hard to provide an excellent service.   I will be asking them to do a few more jobs for me.

Sam and the team at Prestige brickwork were polite, on time, tidy and completed great work at our home. They sorted out problems with the exterior walls on our house and built a beautiful new retaining wall in our tiered garden. We couldn't be happier, they even came back to jet wash our driveway. Thank you.

From start to finish Sam and his team have been a pleasure to work with. Provided a competitive quote after a worrying survey and reassured us it wasn't as bad as the survey had said. Then proceeded to come and do the repointing work and adding missing lintels once we had moved in. All of the team were very professional and cleaned up nicely after finishing. Really great service and would highly recommend them!

Sam quoted quickly and was approachable to discuss ways to proceed. Scaffolding went up lickety split (arranged by Sam via another company), and Harrison and team turned up to begin power-tooling the concrete render off the worst two walls on my detached house. What could have been a worrying and troublesome period was made about as good as it could be by Harrison and the workmen themselves. They were thoughtful, interested, careful with our property and seemingly genuinely keen to make a positive difference to the house. The phase where the damaged walls were laid bare - wet pointing, damaged bricks, horrible window surrounds with holes and foam, was the worst, but I was encouraged by the lads that this was not the worst they had encountered, and gradually, with replacement bricks and lime pointing, the house started to look solid again. The interior walls are already less cold, and we feel happier that no more damage is being done to the fabric of the building. The cost was substantial, but when you look at the man-hours, materials and tools used, I’d say it was very fair. I’d have these guys back in a heartbeat.
