Frequently Asked Questions About Pool Closing

Pool closing prices are influenced by factors such as pool size, filtration system type, the number of water features, and whether your pool includes a heater or spa attachment. Smaller residential pools typically cost less, while larger pools with complex systems may require additional labour and chemicals. At GBI Pools, we provide personalized quotes so you know exactly what services are included, with no hidden surprises.

The best time to schedule a pool closing is when the water temperature consistently falls below 15°C (59°F). Cooler water helps prevent algae growth, making spring openings easier. In Ottawa, most homeowners plan their pool closing for mid-September through October, depending on the weather. Booking ahead ensures you secure a date before temperatures drop suddenly.

A poorly closed pool can suffer serious winter damage, including burst plumbing lines, cracked filters or heaters, structural damage to the liner, and expensive repairs come spring. Even small oversights like leaving water in the pump or not sealing fittings can create issues. Professional pool closing ensures your system is fully winterized and protected against freeze damage.

Yes, but it’s not just about chlorine. We use a carefully measured blend of winterizing chemicals, including algaecides, shock treatments, and stabilizers, designed to keep water clear, prevent algae, and minimize scale or staining. This allows your pool to remain in stable condition through months of inactivity, so you don’t face cloudy or green water in the spring.

Yes. Our commercial pool closing services are tailored for hotels, fitness centres, apartment complexes, and community facilities. These services include not only standard winterization but also detailed reporting, safety compliance checks, and coordination with property managers to ensure everything meets health regulations. This proactive approach reduces liability risks and helps facilities reopen quickly when the season begins again.
