Cracked Brickwork Repair in Birmingham

Maple Home Improvements provides professional cracked brickwork repair for properties across Birmingham and the surrounding West Midlands. We repair cracks in walls using proven techniques such as crack stitching and wall tie replacement, reinforcing the masonry and disguising the repair to match the surrounding brickwork.

Cracks result from movement in the brickwork beyond what the masonry materials can accommodate. Identifying the type and cause of the crack is the first step in providing a lasting, structurally sound repair.

UNDERSTANDING WALL CRACKS

What Causes Cracks in Brickwork?

Cracks in walls commonly appear where the brickwork is over-stressed, such as over front doorways and below larger windows, particularly bay windows. Temperature fluctuations, moisture changes, or minor ground movement can cause this stress and slight movement in the brickwork. Cracks occur when this movement exceeds what the masonry materials can accommodate.

Brickwork cracks fall into three categories. Cyclical cracks open and close seasonally, passive cracks do not increase in length or width, and active cracks increase in width and/or length over time. Identifying which type you have is essential to specifying the correct repair.

Common Signs You Need Cracked Brickwork Repair

  • Cracks above front doorways or entrances
  • Cracks beneath windows, especially bay windows
  • Stepped cracking following the mortar joints
  • Cracks that widen or lengthen over time (active cracks)
  • Cracks that open and close with the seasons (cyclical cracks)
  • Bulging brickwork or mortar beds
  • Signs of corroded or failed wall ties
  • Water entering the property through cracked masonry

REPAIRS MATCHED TO THE CRACK

How Do You Repair Cracked Brickwork?

The correct repair depends on the crack’s type, width, and cause. Cyclical and passive cracks, and generally those that are narrower, can usually be repaired with a brickwork stitching technique, while cracks caused by corroded wall ties require replacing the ties themselves.

Crack Stitching

Crack stitching reinforces and strengthens the wall while allowing a small amount of flexibility and cyclical movement. It involves bonding shaped and twisted stainless steel rods, called Heli bars, into the wall to stitch the masonry across the crack at regular intervals, avoiding the need to rebuild the masonry.

How Crack Stitching Works

Cut horizontal channels at regular intervals across equal sides of the crack to the correct depth, then flush with fresh water to remove debris and reduce moisture loss from the grout or resin. Fill the channels with grout or resin from the back, then push in the Heli bars so they are fully encapsulated.

Repointing and Sealing

Once the Heli bars are installed, the cuts are repointed to disguise the crack stitching and matched as closely as possible to the surrounding wall. The cracks are also sealed to ensure no further expansion caused by water entering the cracks and freezing in cold weather.

Wall Tie Replacement

Wall ties are small metal strips or bars that span the cavity and tie the external and internal walls together. If a wall tie corrodes, the resulting rust can expand, putting pressure on the surrounding masonry and causing bulges and cracks. We can install replacement wall ties suitable for use with brick, block, concrete and timber.

DONE CORRECTLY

Why Correct Cracked Brickwork Repair Matters

A crack that is simply filled without addressing the underlying cause is likely to reappear. Diagnosing the type of crack and the reason for the movement is essential to providing a repair that lasts and protects the structure.

  • Correct Diagnosis – Identifying whether a crack is active, passive or cyclical, and whether wall ties are involved, ensures the right repair method is used rather than a cosmetic fix that fails over time.
  • Structural Reinforcement – Crack stitching with Heli bars reinforces the wall and provides support to prevent further cracking, while still accommodating small, natural movement in the masonry.
  • No Need to Rebuild – Crack stitching avoids the need to rebuild sections of masonry, making it a less disruptive and more cost-effective solution for many cracked walls.
  • Invisible, Weatherproof Finish – Repairs are repointed to colour-match the surrounding wall and sealed against water ingress, preventing freeze-thaw damage and keeping the finished wall looking as intended.

COMPLETED TO A PROFESSIONAL STANDARD

Our Cracked Brickwork Repair Process

Successful crack repair depends on correctly diagnosing the cause of the movement before any work begins. Assess the crack, choose the right technique, and finish the repair neatly so it blends with the surrounding brickwork.

01

Survey and Diagnose

We inspect the cracked brickwork, identify whether the crack is active, passive or cyclical, and determine the underlying cause, such as movement, moisture or corroded wall ties.

02

Reinforce the Masonry

We cut channels across the crack, flush them clean, fill them with grout or resin, and install stainless steel Heli bars, or replace corroded wall ties where these are the cause.

03

Repoint and Seal

We repoint the cuts to match the surrounding wall as closely as possible and seal the crack to prevent further expansion from water freezing within it.

COMPLETE EXTERNAL PROTECTION
