Mississauga Pool Owners: Why You Should Open Your Pool Early This Spring

If you live in Mississauga and own a backyard pool, you’ve probably asked yourself: When’s the right time to open my pool?

At Pallett Pool & Spa, we’ve helped hundreds of local homeowners answer that question with confidence. And here’s our professional recommendation: if you have a safety cover, opening your pool early—ideally in April—is the smartest move.

While safety covers offer great protection against accidents and large debris during the winter months, they don’t completely block the elements. Many pool owners mistakenly believe they can leave their pool closed longer if they use a safety cover. But in fact, the opposite is true—and here’s why.

Safety covers block 95–99% of sunlight, but not all of it. That last few percent of UV light may seem insignificant, but it’s enough to kickstart algae growth once spring temperatures rise. Unlike solid tarps or vinyl covers that block 100% of sunlight, safety covers allow just enough light through to create problems if the water is left stagnant for too long. Opening early allows us to begin circulation and treatment before algae can take hold—saving you from costly clean-up later.

Safety covers are designed to keep out large debris, but they don’t prevent fine particles like dust, pollen, and dirt from entering the water. In Mississauga, our spring season brings a surge of airborne particles that settle quickly into pools. The longer your pool stays closed, the more buildup you’ll have to deal with later. Opening early lets us clean and balance your water before those contaminants become a bigger issue.

When you open your pool early, you get ahead of potential equipment issues. We can spot leaks, failing parts, and filtration problems before the warm weather hits—giving you time to address them before summer is in full swing.

Each May, pool companies across Mississauga become booked solid. Waiting too long means limited availability and slower turnaround times. By opening your pool early, you avoid delays and get priority service from our team.

At Pallett Pool & Spa, we focus exclusively on Mississauga homeowners—so our local clients never get bumped for out-of-area jobs.

Ontario weather is unpredictable. We often get a few unexpectedly warm weekends in April or early May. If your pool is already open, you’re ready to enjoy it the moment the sun comes out—no scrambling for a last-minute appointment.

While larger competitors serve a broader region, Pallett Pool & Spa is focused right here in Mississauga - specifically the communities of Lorne Park and Port Credit. We know the local climate, the unique needs of the homeowners, and how to get ahead of seasonal problems—especially when it comes to pool opening management.
