Underpinning ranges from £16,540 (OCC Construction based in NE10) to £18,412 (Radici Construction North East Ltd based in DH1), 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.
