We have had a continous leak within the walls that lead to downstairs. Now my husband has been doing basic things like caulking and trying to do some basic plumbing to avoid the cost of getting professional help. I finally convinced him to hire outside help to great relief. This company came within a few days of calling and diagnosed what the problem really was, they had to additional work but that was okay, because it seems like everything is okay for now. They are also very pleasant to deal with.
