Engineers and craftsmen, not salespeople.
Foundation repair done by people who would rather lose a job than sell you the wrong method.
- UK-wide coverage and local knowledge
- 20 year remedial warranty
- Diagnostics to remedial work
National Underpinning brings together surveyors, structural engineers, and underpinning crews who have spent careers fixing failing foundations. We cover the whole UK from offices in London, with regional teams that know their patch.
The brief is simple. Diagnose the problem properly. Pick the method that solves it for the long term, not the one that looks best on an invoice. Document the work so insurers, building control, and future buyers can see exactly what was done.
Every job is signed off by a chartered structural engineer. Remedial work carries a 20 year warranty, and we carry full insurance on every installation.
WHAT WE DO
One team, end to end.
Four pillars cover everything we offer, from the first phone call to the final sign-off and beyond.
Diagnostics to remedial
Surveys, drain and CCTV, arborist reports, trial pits, monitoring, engineer's design, and the underpinning works themselves, all under one roof.
UK-wide coverage
Regional crews across England, Wales, Scotland and Northern Ireland, run from our London office. Local knowledge, national standards.
20 year warranty
Remedial work is backed by a 20 year warranty and signed off by a chartered structural engineer.
Financing available
FCA-regulated finance partners let you spread the cost from 1 to 10 years, with a soft-search decision in 24 hours.
IN-HOUSE CAPABILITY
What we handle.
Running the whole job under one roof means no juggling between contractors, no finger-pointing if something needs revisiting, and a single point of accountability for the whole project.
