Mark was a big help. I own the house but currently live on the east coast and rent it out. Mark worked well both with me and our tenants. He kept us informed, worked with tenants to be sure he wasn't intruding more than necessary. The leak was due to a poor remodeling sometime in the house's past. He replaced the leaking portions of the pipe, removed a lot of wet soil from a very tight part of the crawl space, dried the living space on the other side of the wall from where the leak was, sealed the wall, and repaired the carpet. He was prompt and easy to understand. I appreciate his help.
