Easily 5 stars. Rob, Steve, Luis, and Hanlon are all excellent.
I was worried about the company's hourly rate until I realized that it includes 3-4 people working at the same time on the problem, testing and measuring every possible source of your leak. The amount of workers more than justifies the rate. In fact, it saves money in the end. They even did a free consultation.
When my leak came back with a vengeance, the team returned to make tweaks and adjustments to their previous repairs. They did this at no charge.
They explain what's going on, show you what they're doing, and treat you warmly. That goes a long way.
