I contracted a plumber for tenant improvement off a new dental office. When the medical gas was not approved by the fire department, I called Regency plumbing. I found Regency to be extremely knowledgeable, professional, friendly , courteous ,timely and fair in their pricing. They performed all the work on time with high quality workmanship. They obtained the certification and the job was passed by the fire department and city inspectors. They performed beyond my expectations. I plan to use them again and highly recommend them to anyone looking for an excellent plumbing company.
