I was very lucky to find Krisco, the guy who tests water and recommends chemicals is the absolute best in the business. He tests all the products he recommends and knows pool chemistry. Our pool is clear and ready for swimming from spring onward.Recently we needed some repair work done on our pool and I was equally pleased with how professional and knowledgeable the repair guys were. They seem to have a good mix of guys who have been in the business for 20 years and younger guys who are being mentored. I was very happy with the work they completed.
