Underpinning ranges from £16,460 (Aquatec Builder based in OL10) to £17,604 (Tetrosyl based in OL16), 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 OL12 by posting a job with HaMuch and we will send it to extension builders in OL12.
