Cavity wall tie surveys, stainless steel replacement ties and structural crack stitching that stop movement and restore your brickwork. Covering Harrow & Pinner, Enfield and Ealing and across Middlesex.
Book a surveyHorizontal cracks every few courses of brickwork, bulging walls and lifting window sills are classic signs of failing cavity wall ties, a problem we find in many Middlesex homes built with early mild steel ties.
Other cracks have different causes. Our surveyors inspect the ties inside the cavity with a borescope and assess any cracking before recommending a repair.
The 1920s and 1930s houses that make up much of Middlesex were among the first built with cavity walls, and their original ties are now commonly corroded.
We replace wall ties and stitch cracked brickwork across Harrow, Hounslow, Ealing, Enfield and Twickenham.
Much of Middlesex was built up in the 1920s and 1930s, so interwar semis and terraces are everywhere, alongside Victorian terraces in Twickenham, Hounslow and Ealing and older riverside cottages. Interwar cavity walls were often built with mild steel wall ties that are now corroding, and suspended timber floors with blocked air bricks are a frequent cause of rot.
Riverside towns such as Shepperton, Sunbury, Staines, Twickenham and Teddington sit on Thames gravels with a high water table, and parts are in the river's flood plain. That brings damp cellars and moisture pressure to ground floors close to the river.
Metro-land semis on London Clay, where seasonal ground movement and mild steel wall ties lead to cracked brickwork.
Large areas of 1930s housing on clay, where wall tie failure and condensation are frequent findings.
Edwardian family homes, many converted into flats, alongside 1930s semis with corroding wall ties.
Cavity walls are held together by metal ties bridging the gap between the inner and outer leaves. Older mild steel ties corrode, and as the rust expands it lifts the mortar joints, causing horizontal cracking. Eventually the ties can fail completely and the outer wall can bow away.
Where ties have failed, we install high-performance stainless steel replacement ties in the pattern required by current building regulations and, where necessary, isolate the old corroded ties so they stop expanding.
Where cracking has already occurred, structural crack stitching restores strength. Mortar joints are raked out, high-tensile stainless steel helical bars are bonded in with specialist resin, and the joints are repointed to match, giving a strong, discreet repair.

If you’ve noticed any of these issues, arranging a professional survey is the best way to identify the cause and prevent further damage.
We drill small holes into the mortar and use a borescope (a small camera) to see the ties in the cavity, without opening up the wall.
