Underpinning ranges from £16,940 (Marshall & Son Builders based in TS14) to £17,684 (Military Maintenance Ltd based in ts10), 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.
Get quotes to underpin your home in Whitby by posting a job with HaMuch and we will send it to extension builders in Whitby.
