Structure Repairs London

Specialist Structural Brick Repairs London

Structural integrity is the most critical aspect of property maintenance. In London, our unique geological makeup (London Clay) combined with aging Victorian and Georgian infrastructure means that masonry movement is a common, yet serious, issue.

Common Signs of Structural Masonry Failure

London homeowners should be vigilant for these “red flags.” If you notice any of the following, a professional structural assessment is essential

Diagonal Cracking

Usually found around window frames or doors, these often indicate subsidence or lintel failure.

Horizontal Cracking

Often a sign of wall tie failure or expansion issues.

Bowing or Bulging Walls

A serious sign that the brick "skin" is detaching from the internal structure (common in older solid-wall properties).

Sagging Window Arches

Indicating that the structural support above the window has shifted or decayed.

Our Specialist Structural Repair Solutions

We utilize modern, “invisible” repair technologies that avoid the need for unsightly “star plates” or expensive rebuilding.

Helical Crack Stitching

This is the industry-standard method for repairing cracked masonry. We use stainless steel helical bars (often referred to as Helifix systems).

  • The Process: We cut horizontal slots into the mortar beds across the crack. The helical bars are then grouted into place using high-strength thixotropic resin.
  • The Result: The bars act as “internal stitches,” distributing the structural load across the wall and preventing further separation. Once repointed, the repair is completely hidden.

Lintel Repair and Replacement

Many older London properties rely on timber or weak brick arches above windows. Over time, these rot or shift, causing the brickwork above to drop.

  • Our Solution: We install new steel lintels or reinforce existing masonry with helical “beaming.” This creates a hidden structural beam within the brickwork itself, supporting the weight of the wall above without changing the property’s appearance.

Wall Tie Replacement

In cavity wall properties, the metal ties holding the outer brick skin to the inner wall can rust and expand. This causes horizontal cracks and can lead to the outer wall collapsing outward.

  • The Process: We use specialized metal detectors to locate old ties, isolate them, and install new stainless steel remedial wall ties to pull the building back together.

Lateral Restraint Installation

If a wall is bowing outward, it usually means it has detached from the floor joists. We install lateral restraint ties that screw into the timber joists and are resin-bonded into the brickwork, “anchoring” the wall back to the heart of the house.

Will crack stitching stop my house from moving?

Crack stitching is designed to stabilize the masonry. If your house is actively subsiding due to a water leak or tree roots, those issues must be solved first. Once the ground is stable, our repairs "stitch" the building back into a single structural unit.

How much do structural brick repairs cost in London?

A standard crack stitching project (approx. 5-10 bars) typically costs between £800 and £2,500 depending on access and mortar type. Replacing a failing lintel can range from £600 to £1,200 per window. We provide fixed-price quotes after a site visit.

Do I need a structural engineer?

For minor cracking, our 30 years of experience allow us to assess and repair. For major bowing or deep foundational cracks, we always recommend a structural engineer's report first. We can then work directly from their specifications.

Is the repair visible after you finish?

No. This is the beauty of our system. Because we embed the reinforcement within the mortar joints and then repoint over them, the stainless steel bars are buried deep inside the wall. Your home will be stronger, but it will look exactly the same.
