We’ve been using Dave since we moved into our house in 2010. He’s been great with opening and closing our pool, and helping us «novices» to learn the ropes of pool care. His prices are very reasonable, and he’s very quick with his appointments. We’ve never had to wait more than a week for an opening or closing. And he’ll come out in all weather — we opened the pool last year in the 38 degree temperatures(!) of May.
