I am impressed by the work ethic, knowledge, responsiveness, fairness, and focus on getting to the root of our pool equipment issues. Jonathan's breadth of knowledge is wide and expansive. The service provided has been thorough, personal and timely, and the cost very fair and reasonable. Jonathan spent nearly 2 hours (free of charge) when he first came out to our house and did a far more thorough checkup on our pool than the pool company we hired (and paid) for our pool inspection before we bought the house. Wish we had Jonathan do our pool inspection instead back then, but at least we will have his expertise going forward.
