St. Catharines Pool Closing

When the leaves begin to change and temperatures begin to drop it is time to start thinking about closing your pool for the off-season. It is easy to forget about a swimming pool when it is not being used regularly but as time goes on, a small issue will go from bad to worse.

Failing to close your pool properly can mean green water, foul smells, a more difficult opening in spring and a whole lot of unexpected damage. Instead of waiting for a worst-case scenario call a local Puddle Pro. A proper St. Catharines pool closing prevents damage and algae growth, paves the way for an easier opening in spring and gives you peace of mind throughout the off-season. 

Fall Pool Care: What to Know 

The internet is full of tips for fall pool maintenance but not all of these are effective. Instead of trusting a random internet search, have a local Pro guide you on how to best protect your pool for the winter. Our experts are highly trained and experienced in treating pools that are both outside and indoor, as well as inground pools or an above ground pool model. 

Timing is Everything: Traditionally, the best time to close your pool is just after the September long weekend and the best time to open your pool is just before the May long weekend. Relying on dates isn’t always the most effective way to navigate your seasonal pool care. When the average outdoor temperatures reaches 15 degrees, it is time to close down your system to avoid freezing and the damage it causes. 

Avoid Freezing: It takes prolonged exposure to sub-zero temperatures for large bodies of water, like pools, to freeze over completely. Smaller amounts of water in lines and around pool components will freeze a lot faster than that. Dropping the water level to just below the skimmer line prevents water from entering your system where it can freeze and cause damage. Cold temperatures cause plastic to become brittle and crack while frozen water will expand inside pipes. Frozen water expands up to 9% which might not seem like much but it is enough to cause pipes to burst. Dropping the water lines and winterizing drain plugs prevents water from seeping into sensitive areas where it will cause damage. 

Winterizing Chemicals: Water chemistry is often a top priority at the height of the swim season but as the weather drops and pools are used less frequently, it is easy to forget about  keeping up with chemicals. An application of winterizing chemicals doesn’t only prevent freezing it also prevents algae growth. 

Filters & Pool Equipment: It is a good idea to remove any detachable components so they can be dried and stored over the course of the off-season. Flushing return lines is also a great way to keep unwanted water out of vulnerable areas. This is also an opportune time to install safety covers to keep debris out and prevent accidents or injury for people and pets that might be around the pool area while it is closed.

St. Catharines Pool Closing: Frequently Asked Questions

When should I close my pool for the winter in St. Catharines?

It is best to wait until the water temperature has dropped and stayed cool. Closing too early during a warm Ontario autumn can allow algae to grow under the cover, leading to a much more difficult opening next spring.

Is 'winterizing' pipes necessary for pools in St. Catharines, ON?

Absolutely. Even a brief cold snap can freeze stagnant water in your plumbing. Puddle Pools uses high-pressure air to 'blow out' the lines and installs specialized winter plugs to protect your underground pipes from cracking.

What chemicals are used to winterize a pool in Ontario?

A proper St. Catharines closing requires a combination of long-lasting algaecide and sequestering agents to prevent staining. This protects your pool surface from mineral scale and organic growth during the long off-season.

Should I lower the water level in my pool for the winter?

Yes, we typically lower the water level below the skimmer mouth to protect the plastic components from ice expansion. Our team ensures the level is perfectly balanced to support your cover while keeping the structure stable.

How do I choose the right winter cover for my St. Catharines pool?

You need a cover that can handle Ontario's seasonal debris and heavy precipitation. Whether you prefer a solid tarp or a mesh safety cover, we provide custom-fit solutions to keep your pool secure and your family safe.
