I've referred James and his team to diagnose problems at my clients' houses that other companies weren't able to figure out. They have never let me down on the referrals. I've also had them fix broken drains, install sinks, water heaters and re-pipe homes. Their prices are always very affordable and they never try to sell you more than you need. They are currently going to install a new kitchen sink and fixtures at my home. They are by far one of the best plumbing companies in Columbia.
