Posting on behalf of a friend who isn't on Mumsnet, not sure if posting in right place but not sure where else to post.
Long saga, will keep it brief. Friend has a leak in her bathroom, been going on for months. Buildings insurance is through managing agent, not her own. Insurer has engaged plumber who continues not to be able to find the source of the leak, which is intermittent. Friend has taken photos of the damp and even videos of the leak showing where leak is coming from but plumber saying he can't find source. Loss adjuster doesn't know what to suggest. Managing agent not being helpful. Distressing situation - any thoughts as to where she goes from here?
