When to close
Your pool

Close your pool once the water stays below 12 to 15 °C, usually between late September and late October in Quebec. The rule is not a date, it is the water temperature.

The right time

When to close?

Below 12 to 15 °C, algae stop growing and the water keeps all winter under the cover. That is the right time to close.

Above that threshold, warm water and organic matter lead to green water in the spring. Too late, and frost threatens your plumbing.

In Saint-Jérôme, Saint-Sauveur or Saint-Colomban, the water cools down earlier. Aim for the second half of September or early October.

In Mirabel, Blainville, Boisbriand, Sainte-Thérèse, Terrebonne and Saint-Eustache, most pools are closed between late September and late October.

Same period as the North Shore, sometimes into November during a mild fall.

A pool closed with water still at 22 °C spends the winter in the dark with organic matter. In the spring, the water is green and needs several days of treatment.

Frost attacks the plumbing, not the pool water. A line still full of water freezes and cracks; on an inground pool, the repair requires digging. The skimmer, pump and filter can also crack.

Why 12 to 15 °C?

Below that threshold, algae stop growing and the water keeps all winter. We close pools from September 1 to December 15, depending on temperature and availability.

Our advice

Book your date in September and choose a day between late September and late October. The closing is done in a single visit, and your date is confirmed online in 2 minutes.

Do I need to be home during the closing?

No. We only need access to the yard and the equipment. The day before, we confirm a four-hour time window.

How much does a closing cost?

Above-ground: $179.99, $419.99 or $599.99. Inground: $279.99, $519.99 or $799.99. See the price guide
