These folks don't do residential plumbing work at all don't call them for a repair you'd be better off googling it and fix it yourself.the woman in the office? She's extremely rude and complacent. Do yourself a huge favor and get some other outfit to fix your problem. Nuff said. T2

Heater they installed started leaking after being installed for only a few months. Called to ask if there was a warranty, and they said they would have to send someone out to see. The person came and attempted to fix, with no mention of cost. It started leaking again a day later, so I called them back and they sent someone else to fix. Still no mention of cost. Months later I get a very large bill from them for the repairs. Do not expect any transparency or good service, but at least they fixed the issue eventually.
