Our Clients Say

"We have had a pool for over 35 years which has been looked after by various members of the family. When it became apparent that the pool was in need of painting/resurfacing, we made contact with Sparkling Pools. We were dreading the thought of the disruption, noise, dirt and having contractors on site for several weeks.

We had the pleasure of meeting Grant whose considerable knowledge of swimming pools is so impressive. He checked out not only the pool finish, advised us of the various alternatives open to us, but also the machinery and ancillary equipment. We were so impressed that we gave Sparkling Pools our contract to resurface and we enjoyed a textbook example of a perfect contract."
