Calendar
The right time to open and close your pool
Closing
CAA-Québec calls October the ideal month. Quebec pool retailers advise closing as late as possible, just before the first frost: end of October, or early November in southern Quebec.
The benchmark: water below 10 °C (50 °F), which slows algae and keeps the water clear until spring.

Do you service above-ground pools?
We specialize in in-ground pools: openings, closings, liners, leaks and repairs. For an above-ground pool, give us a call: we will tell you if we can help.
How is the price calculated?
The prices shown are our base prices, in Laval. The further away you are, the higher the travel fee. We confirm the price before the visit.
Do you go to Montreal and the South Shore?
Yes, gladly! We also serve Montreal and the South Shore. A travel fee may apply depending on the distance.
What is a turnkey opening?
We fully drain your pool, then clean it thoroughly. Once the pool is clean, we wait for it to be filled, then come back to start your equipment back up.
My pool is losing water. Where do I start?
Start by calling us. With our experience, we can very often tell over the phone whether the leak is in the liner or the plumbing. Then we book the right appointment to find the exact spot.
When should I close my pool?
CAA-Québec calls October the ideal month. Quebec pool retailers advise waiting until the water is below 10 °C (50 °F), just before the first frost: end of October, or early November in southern Quebec.
Are you available on weekends?
Yes. We work 7 days a week, weekends included.
