Right now, New Jersey is in the middle of summer — the peak season for beachgoers, water parks, and outdoor tourism. The summer season officially runs through the middle of September, bringing hot and humid weather with temperatures averaging above 27°C (80°F).
Your pool is getting daily use, kids are splashing around, and weekend barbecues are in full swing.
But here’s something most pool owners don’t think about in July: winter is coming.
And in New Jersey, winter doesn’t mess around.
Why You Should Think About Pool Closing Companies NJ Now
It might feel strange to talk about closing your pool when you’re still in the middle of summer. But the best pool closing companies NJ has to offer get booked up fast — and if you wait until September, you might find yourself scrambling.
Here’s the reality of New Jersey’s seasons:
| Season | What’s Happening | What You Should Be Doing |
|---|---|---|
| Summer (Now – Mid Sept) | Hot, humid, peak swimming season. Temperatures average above 27°C (80°F). Algae grows fast, chlorine depletes quickly | Enjoy your pool! Maintain weekly chemical balance. Run pump 8-12 hours daily-9 |
| Late September – October | Temperatures drop. Leaves start falling. Water cools below 65°F– | Schedule your pool closing. Book early — companies fill up |
| November – March | Freezing temps, snow, ice, and unpredictable freeze-thaw cycles– | Pool is closed and winterized. Consider winter watch programs |
| April – May | Risk of hard freeze passes. Overnight temps stay above 50°F | Schedule spring opening. Test water before opening |
Planning ahead now means you’ll get your preferred closing date, the same trusted technicians, and peace of mind that your investment is protected.
What Happens If You Don’t Close Your Pool Properly?
New Jersey winters are brutal on pools. We get freezing temperatures, snowstorms, ice, and that unpredictable freeze-thaw cycle that can wreck pool equipment if you’re not careful
A pool that isn’t closed properly? That’s a recipe for:
- Cracked pipes from water freezing and expanding inside plumbing lines
- Damaged pumps and filters that weren’t properly winterized
- Algae and bacteria growth from imbalanced water chemistry
- Stagnant water that breeds mosquitoes and creates foul odors (which can actually get you fined in some NJ towns)–
- Spring opening costs that are 3-5x higher than a professional closing
In fact, many New Jersey towns have ordinances requiring pools to be properly covered and chemically treated during the off-season to prevent stagnant water and insect breeding–

The sweet spot: Late September through October, before leaves and cold weather take over–
But here’s the catch — if you wait until the last minute, you might be out of luck. Professional pool companies get booked up quickly in the fall.

What You Can Expect to Pay
Pool closing prices in New Jersey can vary based on your pool type, size, and the services included. Here’s a general breakdown based on real New Jersey pool companies:
| Service Level | Typical Cost | What’s Included |
|---|---|---|
| Essential Closing | $400 – $450 | Blow out lines, winterize filter, add winterizing chemicals, cover pool-10 |
| Standard Closing | $450 – $500 | Essential services plus removing ladders, handrails, and accessories-10 |

DIY vs. Professional Pool Closing
Some homeowners try to close their own pools to save money. It’s possible, but there are risks.
If you close your own pool, you’ll need to:
- Balance chemicals correctly for winter
- Blow out all plumbing lines (requires a powerful air compressor)
- Properly winterize your pump and filter
- Install and secure your cover safely
Here’s the reality: A professional crew can close a pool in 60-90 minutes. A DIY job can take you 4-6 hours — plus multiple trips to the store for supplies.
And if you mess up? You won’t know until spring, when you discover that cracked pipe, damaged pump, or green swamp that costs thousands to fix.
Red Flags When Choosing a Pool Closing Company
Not all pool services are created equal. Here’s what to watch out for:
| Red Flag | What to Do |
|---|---|
| Can’t provide proof of license and insurance | Ask for their NJ HIC registration and verify it |
| No local references | Ask for references from the past year |
| Rude customer service on first call | Trust your gut — it won’t get better |
| Pressures you into overpaying upfront | Legitimate companies don’t ask for unreasonable deposits |
| Changes business name frequently | Could be trying to escape bad reviews |
