I have owned my house for over ten years now, and the plumbing issues that have come up did cause trouble. The first time I had a pipe burst inside the house, I called in a local handyman who was okay but didn't do an adequate job. This meant I was once again back to square one. I had to call in a real service to do the work for me, and they were efficient and great to work with. I would say you should always choose the pros because that is what plumbing is all about.
