Summer is officially over, and the days are getting shorter and cooler. For many Oakville pool owners, this brings up the most pressing question of the fall season: “When is the best time to close my pool?”
You might be tempted to close your pool as soon as the first chilly night hits, but at Crush Pools, we have a different recommendation. The key to a healthy, sparkling-clean pool next spring is a proper, late-season closing.
The Golden Rule of Pool Closing: Don’t Rush It!
We always recommend waiting until after Thanksgiving to close your pool. There’s a good reason for this. In Southern Ontario, the warm days and cool nights of early fall create the perfect breeding ground for algae. By keeping your pool open and circulating as long as possible, you can actively prevent algae growth. This is especially crucial for those with safety covers, as algae can multiply unseen over the winter, leaving you with a costly and time-consuming mess to clean in the spring.
Think of it this way: what do you call a pool that gets closed too early and turns green over the winter? A “surprise” for next year’s pool opening!
If you don’t have a safety cover on your pool now is the time to get one.
The Steps to a Worry-Free Pool Closing
A successful pool closing is more than just putting on a cover. It’s a precise process that protects your investment from the harsh Oakville winter.
- Clean and Balance: Before anything else, your pool water needs to be clean and balanced. This means removing all debris, vacuuming the bottom, and ensuring your pH, alkalinity, and sanitizer levels are all within the correct range. This final balancing act ensures the water won’t become corrosive or scale-forming over the winter.
- Winterizing for Freeze Protection: This is the most critical step. Water left in your plumbing lines will freeze, expand, and crack your pipes, leading to thousands of dollars in repairs. Our experienced technicians use a powerful air blowers to blow out all water from your pool’s lines. We then install “Gizmos” in the skimmer and winter plugs in the return jets to prevent any water from re-entering.
- Installing the Cover: After the pool has been cleaned and balanced, the lines and equipment have been blown and plugged we install your winter cover. You want to make sure you cover is installed properly so that it does not come out of place over the winter causing a nasty spring clean up. We ensure your cover is properly secured to protect your pool from debris all season long.
