I have been using Greg Free for pool opening/closing and repair or maintenance issues for about 4 years now. I'm sorry I didn't find them years ago. Many pool companies in Oakville have a poor attitude toward customer service and inevitably employ summer students who aren't given proper training. The result is often service that's expensive and sub-standard. At Greg Free, the staff is mature, knowledgeable and dependable. In addition to seasonal opening and closings, I have purchased a new pump and a safety cover. They have given me excellent service and competitive pricing. I would recommend them to anyone.
