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.
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.
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.
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.
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.
