Pool Opening & Closing (Seasonal)

Professional pool opening and closing services in Ottawa for the short outdoor swimming season. Ottawa pools typically open in late May after the last frost risk passes and close by mid-September as overnight temperatures drop, giving homeowners roughly 14 to 16 weeks of swimming. Proper seasonal service is essential in Ottawa where winter temperatures regularly reach minus 30 degrees Celsius and pools sit frozen for six months or more.

Spring opening includes safety cover removal, equipment reconnection and inspection, plumbing line clearing, filter and pump startup, initial chemical shock treatment and water balancing. Fall closing includes thorough cleaning, water level adjustment, antifreeze treatment of plumbing lines, equipment drainage and shutdown, and winter cover installation.

Poor winterization in Ottawa's climate can lead to cracked pipes, damaged pumps and liner tears from ice expansion, making professional closing one of the most important pool services of the year.
