Had main drain surveyed and bad leak found in a very awkward place, at bend in the pipe under our kitchen. Can be patched but will probably need the floor digging up, according to drain firm. Should I get a second opinion on whether it can be patched without digging? Man who did survey said it's about 80% certain it will need digging but he's going to discuss it with his lining expert.
Also, as this is a clay sewer pipe, they of course recommend lining it
- any advice on the best technoloy and cost for this? They want to charge £95 a metre (this is London) but don't charge VAT.
Thanks
