WOW!!!! Talk about excellent service! Water in the middle of my house - no one, and I mean no one could identify the source until Chris from Pro Tek came out. We used other plumbers, foundation inspectors, concrete experts and one of the Leak Detection companies, but no one had a clue. Chris immediately knew where to look and what to check and determined the cause, cleaned out the water and used the video to determine integrity of the vent. HE WAS WONDERFUL AND DID A FABULOUS JOB. If you have a leak or any similar problem, do yourself a favor and call Pro Tek FIRST!!!!!
