It's so hard to even get people to show up in this part of the world. I'm so grateful to these guys at Complete Comfort.

Found a leak from the main floor dripping from the ceiling of the finished basement on a Saturday…read moreafter 4:30 pm. Contacted my regular plumber (not Cox) and found out he was out of town on vacation. Finally called Cox after 5 pm. Was pleasantly surprised when he answered the phone. He had other jobs already scheduled but was able to come by on Sunday afternoon. (I had shut off everything I could think of so the leak had stopped. Was afraid it was the toilet by the kitchen.) He was able to arrive an hour earlier than he expected which was great. Long store short... he was able to diagnose the actual problem (wasn't the toilet) and the issue was resolved. Very professional, very knowledgeable, very personable. Nice guy and the cost was actually less than I expected for an emergency weekend plumbing call. Hope I never need a plumber again but I would definitely use Cox Plumbing again.
