Underpinning ranges from £17,212 (MOLLISON CONSTRUCTION based in PH11) to £17,900 (Bell & Whyte based in KY14), 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 PH1 by posting a job with HaMuch and we will send it to extension builders in PH1.
