Repair options we may recommend
Gable restraint straps
Steel straps are fixed across at least three rafters or ceiling joists, with blocking packed tight between the last timber and the wall, then turned down and fixed into the gable masonry. They are fitted from inside the loft, so the outside of the house is usually untouched.
Best for: Sound gables with no connection to the roof
Remedial ties through the gable
Where loft access is poor or the timbers sit away from the wall, stainless ties are drilled in from outside and fixed into the roof structure or the inner leaf. This suits gables where boarding, insulation or a converted loft makes internal strapping awkward.
Best for: Converted lofts or gables with difficult internal access
What to expect when we carry out gable end wall repairs
Check from the loft
Much of the diagnosis happens in the roof space. Photos of where the rafters, purlins and joists meet the gable, plus outside shots of the verge, tell us a great deal before we visit.
Measure the lean
On site we plumb the gable, look for cracks at ceiling line and apex, and check the chimney and verge. Large movement or an unclear cause is a job for an engineer, whom we can bring in for you.
Strap, tie or rebuild
Straps and blocking are fitted at the spacing required, ties drilled and fixed, or the upper gable rebuilt course by course with restraint built in. Roofing along the verge is relaid and bedded or dry-fixed.

Does the ground around Llantwit Major cause cracking?
Cardiff is built on Mercia Mudstone, river gravels and alluvium, and the Vale of Glamorgan on Lias limestone and clay. Soft alluvium near the rivers and docks can settle. Only an investigation can say why a particular building has moved.
What are gable restraint straps?
Gable restraint straps are steel straps that tie the gable wall to the roof timbers so it cannot move outward. They run across several rafters or joists with blocking between, then turn down to fix into the masonry. Modern houses have them built in.
Is a leaning gable dangerous?
A leaning gable can be dangerous, because the top of the wall is heavy and high. A slight, long-standing lean is often stable, but fresh cracks, loose bricks near the apex or a lean that worsens after storms should be checked quickly. If bricks are loose, fence off the ground beneath it.
