A south‑facing bay pulling away from the main wall after a dry summer — stabilised in a single afternoon, with the family at home throughout.
<p>A late‑Edwardian terraced house with a two‑storey south‑facing bay that had started pulling away from the main façade. Diagonal cracking around the upper window frame had widened past a 5p coin in three months following the dry summer of 2024. Insurer’s loss adjuster had recommended traditional underpinning quoted at £28,500 with a two‑week timeline.</p>
<p>We took a single laser baseline across the front elevation, mapped the London‑clay column to a depth of 2.8m via a drainage survey and trial pit, and treated the soil beneath the bay corners with 16mm tubes — about the size of a 5p piece. Eight injection points across the bay perimeter were lifted and re‑bedded over the course of one afternoon.</p>
<p>Front elevation came back to within 4mm of its original line. No further movement at the 12‑month follow‑up monitoring visit. Owner reported zero disruption to family life — the kids were doing homework two rooms away while we worked.</p>
Cracks in walls — when to worryTell us what you're seeing. We'll book a same‑week survey, produce a written engineering report, and quote in plain numbers.
