The Perfect Time for Your Pre-Winter Pool Closing in Pennsylvania


If you’ve been around our blog for long, you already know the importance of winterizing and closing your pool at the end of the season.

You do know that, right?

Unless you’re planning to adopt baby alligators next spring, you must close your pool correctly. If you want to raise baby alligators, finding a swamp when you uncover your pool will work just fine. But, for the rest of us who want to start next year’s pool season by, ahem, swimming, the most important step in opening your pool next year is properly closing it this year. So, now that you’re convinced winterizing your pool is vital, you’re probably wondering one thing: “When do I need to close my pool?”

There are simple factors to consider when picking the perfect time for your pool closing. Here’s what you need to know.

The #1 Consideration in Pool Closing

The temperature is the number one consideration when deciding when it’s the right time to close your pool. If you close it too soon, warm days will heat up the water under your winter cover and speed up algae growth like mad. If you wait too long, the first freeze can cause water to freeze in your plumbing lines and equipment. You’re aiming for a sweet spot right in the middle. Since algae and other bacteria will thrive in a warm pool, wait until temps fall to 65℉ or below.

In PA, that typically means late September through October is the perfect time to winterize and close your pool. So, once Autumn is in full swing and both water and air temperatures are below 65℉ (and you’re confident it will stay that way), it’s a good time to close your pool for the season.

Now offering Curbside Water Testing by Appointment Only!

Visit us online to schedule your 15-minute water testing consultation.

Simply select your store location and choose from the appointment slots available. Due to limited availability, we will only be able to accommodate up to (1) water test per household per week until further notice and increased staffing. 

Bring your water test bottle with a sample of your pool or spa water to your scheduled appointment. Please label the test bottle with your name, and leave it in the marked bin by the front door. Then, just wait in your car while we perform the water test. We will call you with your results and our recommendations for the products you will need to balance your pool or spa water. If you’d like to go ahead and get those products while you are here, we can deliver those curbside, as well. Please know that our staff have been instructed to leave all chemical purchases outside of the front door. Unfortunately, we will be unable to load in your car at this time. Just let us know that you would like to purchase chemicals when we call with your test results, and we can process your order over the phone. Once we have completed your water test, we will leave a copy of the printed out test results, along with your empty test bottle, in the marked bin outside the front door.

Due to the limitations of staff and anticipated demand for this service, we ask that you please arrive on-time for your scheduled appointment to ensure that we can have enough time for a complete and accurate consultation. In order to keep you, our valued customer, and our staff safe, we ask that you please adhere to social distancing guidelines and give our staff at least 6’ of distance during this interaction. Thank you for being a loyal Fronheiser Pools customer!
