Protect Your Pool Investment This Fall with Professional Winterization
As Long Island temperatures begin their steady decline, your backyard pool needs more than just a cover to survive the harsh winter ahead. At All Island Group, we’ve been protecting Nassau and Suffolk County pools for over 50 years, and we know that proper winterization means the difference between diving into crystal-clear water next May and facing thousands of dollars in preventable damage.
Why Professional Pool Closing Matters
Many homeowners think pool closing is simple—drain some water, toss on a cover, and wait for spring. But Long Island winters don’t mess around. When temperatures plummet below freezing, any water left in your lines can expand by up to 10%, cracking pipes and destroying expensive equipment in a single freeze cycle.
We’ve seen it happen too many times: families who tried DIY winterization or hired inexperienced services, only to discover green swamp water, failed equipment, and costly repairs when pool season arrives. The frustration of losing those first warm weekends of summer while scrambling for emergency repairs—that’s exactly what we help you avoid.
Our Comprehensive Winterization Process
At All Island Group, we don’t cut corners. Our systematic approach ensures your pool stays protected all winter long:
Complete Water System Protection
We use commercial-grade air compressors to thoroughly blow out every line in your pool’s circulation system—skimmers, returns, main drains, and all plumbing connections. We don’t stop until every drop is removed, because even small amounts of trapped water can cause catastrophic freeze damage.
Precision Chemical Balancing
Our CPO-certified technicians carefully balance your water chemistry to optimal winter levels before closing. Proper pH, alkalinity, and calcium hardness prevent corrosive damage to your pool’s surface and equipment during the long off-season.
Thorough Cleaning & Preparation
We vacuum your pool completely, brush walls and tile lines, remove all debris, and clean or backwash filters. When we close your pool, it’s in pristine condition—which means a faster, easier opening in spring when you’re eager to swim.
Equipment Winterization
Every pump, heater, filter, and automated system receives proper winterization treatment. We drain, clean, and protect each component, removing drain plugs and storing them safely in your pump basket for spring reinstallation.
Professional Cover Installation
We install your winter safety cover with proper tensioning and secure anchoring, ensuring it stays in place through winter storms and protects your water all season long.

What Our Customers Say
Kristin, a Lloyd Harbor homeowner featured in our recent pool closing video, puts it simply: “They’re on time every single Friday. My pool is impeccable. They are so quiet, always respectful, and you’re the best.”
After three to four years with our service, Kristin knows she can count on us. That reliability matters, especially when you’re protecting a significant backyard investment.
Make Your Spring Opening Effortless
Here’s what happens when you close your pool the right way with All Island Group: When we return in spring to open your pool, the water is clear, the equipment starts up smoothly, and you’re swimming within days—not weeks—of opening day. No expensive surprises. No frustrating delays. No lost weekends dealing with problems that shouldn’t exist.
We close pools in pristine condition because we know it helps your pool water open in better condition come springtime. That means a quicker turnaround to get you swimming, and it helps prevent pool finish staining or damage from sitting in cold water during the off-season.
Book Your Fall Closing Today
Long Island pool closings should happen when water temperatures stay consistently below 65°F—typically from late September through October. Once overnight temperatures approach freezing, it’s too late to prevent damage.
Our October schedule is filling up quickly. Contact us today to reserve your closing appointment and ensure your pool is properly protected before winter arrives.
