Underpinning ranges from £17,140 (A & J Halford based in HG2) to £17,420 (Rob Brumfitt Dry Stone Walling based in HG1), but the final cost will depend on the method of underpinning used, how much of your foundations need underpinning and where you live.
Comparing extension builders estimates for underpinning gives you an idea of who will be better value but the best way to compare costs is to get actual quotes.
