Underpinning cost calculator

Realistic 2026 ranges built from the same published rates as our underpinning guide — extent, method and access, with geotech and engineering itemised.

How much of the house is affected? Method Access

Where should we send your itemised estimate?

You'll see it on screen instantly too. We'll only call if you ask us to.

Includes geotechnical report ($1,000–$3,000) and structural engineering ($500–$3,000) — both essential on every underpinning job. Indicative only — the method should come from the engineer's assessment, not this page, and a free assessment turns this into a fixed written quote. We'll follow up with your written estimate by email.
