I have over 40 years experience in the field of construction. Thank you and I hope I will be of service to you.

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.
Get quotes to underpin your home in DH7 by posting a job with HaMuch and we will send it to extension builders in DH7.
