My husband has been using this plumber for at least 20 years. He first used him on an old house that he was refurbishing. We've since used them for various other houses and projects. We have some rental houses that Sipe has done the work on, in fact , we just let them hold the keys. That's how much we trust them. They always come out when they say that they will. Also, they call before doing any costly repairs or order parts.
The only plumbing contractor that we would ever use.
