We became aware of a leak in our property as we noticed the internal walls were becoming wet from the ground up. I have started a claim with my home insurers and they sent out an Investigator from Drainage Advisory Services &amp; Assistance  (DASA) They have determined through their investigation that that the leak appears to be on a Lead main and it is leaking due to the supply pipe effectively being at the end of its useful life.

The pipe runs straight through my house from the little metal flap outside the house on the pavement, straight through to where it attached to the boiler. As it is a water main, is this something you can assist in fixing?
