Crack Repairs Bromley
Expert Crack Repair Services in Bromley
Cracks in buildings are common, but not all cracks are equal. Some are purely cosmetic, while others point to deeper structural problems such as subsidence, movement, or wall tie failure. In Bromley, we often see cracks in older properties, especially those with cavity walls, clay-based soil, or shallow foundations. Identifying the type of crack and its cause is essential before deciding on the right repair.
At City Structural Ltd, we provide crack assessments and permanent repair solutions for both internal and external wall cracking. From plaster repairs to structural reinforcement using crack stitching techniques, we make sure your property is secure and protected. Our team works cleanly, quickly and with the least disruption possible, offering honest advice and fully guaranteed repairs. Whether it’s a small domestic job or a larger commercial issue, we deliver results that last.
Common Causes of Wall Cracks in Bromley
Bromley’s property stock includes a mix of older Victorian and Edwardian homes, 1930s semis, and modern builds. Each type of property can suffer from cracking for different reasons. One of the most common causes is ground movement — especially in clay-rich soil areas like Bickley or Chislehurst. As the soil expands and contracts with moisture levels, it places stress on foundations and walls, leading to cracks.
Other causes include thermal movement, where materials expand and contract due to heat and cold, and poor construction or historic settlement. Wall tie corrosion in cavity walls is another issue we frequently encounter, where metal wall ties rust and cause cracking in the outer brick leaf. At City Structural Ltd, we don’t just patch up cracks — we investigate and treat the root of the problem. This approach ensures your property stays structurally sound and reduces the chance of recurring issues in the future.
Internal Crack Repairs and Plaster Restoration
Internal cracks can appear along ceilings, around door frames, or diagonally across walls. While some may be cosmetic due to old plaster or minor settling, others could signal deeper movement in the structure. Our team assesses the width, location, and pattern of internal cracks to determine if a structural issue is present. If the damage is non-structural, we carry out professional plaster repairs for a smooth, flawless finish.
In cases where movement has occurred, we reinforce the area with appropriate techniques, such as installing helical bars within the wall or improving the foundation support. Once the structure is stabilised, we fully restore the finish using quality plastering materials. Our repair work blends seamlessly into your existing décor, ready for painting or decoration. With years of experience in Bromley homes, we know how to handle everything from hairline cracks to major interior damage in a clean, efficient and respectful way.
Crack Stitching for External Walls
External cracks in brickwork are not just unsightly — they can let in water, cause damp issues, and weaken the wall structure over time. For these types of cracks, we often use a method called crack stitching. This involves cutting into the mortar joints and inserting stainless steel bars across the crack, then bonding them in place with special grout to hold the wall together and prevent further movement.
Crack stitching is effective for vertical, stepped or diagonal cracks in masonry and can be used in both solid and cavity walls. It’s especially useful in older Bromley properties where movement has occurred but the wall is otherwise stable. After the structural repair is complete, we restore the appearance of the wall by repointing and blending the repair into the existing brickwork. Our goal is to leave the wall looking as good as new, while reinforcing it with long-term structural support you can count on.

Frequently Asked Questions
Not always — some cracks are purely cosmetic, while others indicate a more serious structural issue. Hairline cracks in plaster are often caused by natural settling or changes in temperature and humidity. However, larger cracks, especially those that are diagonal, appear suddenly, or continue to widen, could be a sign of underlying movement in the structure or foundation. Cracks wider than 5mm, or ones accompanied by sticking doors or sloping floors, usually warrant investigation. At City Structural Ltd, we offer expert assessments to determine the cause of cracks. Our team can tell the difference between cosmetic defects and signs of potential structural problems. If necessary, we’ll carry out professional crack repairs using methods like crack stitching, resin injection, or even structural reinforcement. It’s always safer to get a professional opinion early before the problem escalates. We provide honest, clear advice based on what’s best for your property and safety.
Structural cracks in brickwork or masonry walls are repaired using methods that go beyond cosmetic fixes. One of the most effective techniques is crack stitching, where we insert stainless steel bars into slots cut into the brickwork. These bars are bonded in place with structural grout to restore the wall’s strength and prevent further movement. In more serious cases, such as those involving foundation settlement or subsidence, additional work like underpinning or ground stabilisation may be required. At City Structural Ltd, we always start with a full structural inspection to determine the cause of the cracking. We then tailor our repair approach to suit the specific building and problem. After the structural repair is complete, we carefully restore the brickwork or render to blend in seamlessly with the rest of the wall. Our crack repair methods are compliant with all UK building regulations and come with guarantees for peace of mind.
The cost of crack repairs in Bromley varies depending on several factors, including the size and severity of the cracks, their location (internal or external), and the cause behind them. Cosmetic surface crack repairs inside your home may cost as little as a few hundred pounds. However, structural crack repairs involving crack stitching or ground stabilisation can range from £800 to several thousand pounds depending on complexity. At City Structural Ltd, we provide free, no-obligation surveys and detailed quotes, so there are no surprises. We’ll assess your property, explain your options clearly, and recommend the most cost-effective long-term solution. We also work with insurance providers in cases involving subsidence or impact damage.
