The structural-crack-repair rate on the platform spans from 150 pounds for a hairline crack to 5,000 pounds for significant subsidence-related movement -- crack stitching using stainless steel helical bars sits toward the lower-to-middle of that range and is not a substitute for a structural engineer diagnosis on genuinely subsidence-related cracking.
Why this matters
Stitching a crack that is still actively moving, without first establishing why it is moving, can mask an ongoing structural problem rather than fix it. Getting this sequencing wrong on a care home risks a repeat, more expensive failure later, and in the worst case a genuine safety issue.
What to do
- 1Commission a structural engineer report before any crack stitching where the crack is wider than a few millimetres, is still visibly moving, or has an unclear cause -- the structural-engineer-report rate on the platform sits alongside structural-crack-repair for exactly this reason.
- 2For a confirmed, non-progressive masonry crack, a helical bar crack stitching system -- such as Helifix HeliBar, available in 4.5mm to 10mm stainless steel diameters -- installed into resin-filled slots either side of the crack is a well-established, minimally disruptive repair that avoids rebuilding the affected masonry.
- 3On a cavity wall, confirm whether both leaves are cracked, not just the visible inner or outer leaf -- both sides need stitching if both are affected, which materially changes the scope and cost of the job.
- 4Keep a photographic record with a dated scale reference (a simple crack monitor or a ruled photo) before and after any stitching repair -- this is the evidence a care home needs if the same location is ever queried again during a CQC inspection or insurance claim.
