Here's Exactly What We Do

First, we balance your water chemistry to prevent corrosion and staining during the off-season. This isn’t just throwing in some chemicals – we test and adjust pH, alkalinity, and sanitizer levels to create the right environment for your pool to sit safely all winter.

Next, we drain water from all equipment and plumbing lines. This is where most DIY attempts fail – miss one line and you’re looking at expensive freeze damage. We blow out every line with compressed air and add antifreeze where needed.

Finally, we install and secure your pool cover properly. A cover that comes loose in a winter storm defeats the whole purpose. We make sure it’s anchored correctly and will stay put through whatever weather Long Island throws at it.

Pool Winterization Services Nassau County

Everything Your Pool Needs For Winter

Our pool closing service covers every detail that matters. We handle inground pools, above-ground pools, and all the equipment that keeps them running. Salt water systems, heaters, pumps, filters – we know how to properly winterize each component.

In Nassau County, we deal with freeze-thaw cycles that can destroy improperly winterized equipment in a single cold snap. That’s why we don’t cut corners on the process. Every line gets blown out, every piece of equipment gets the attention it needs.

You also get a full inspection of your equipment during the closing process. If we spot potential problems, we’ll let you know so you can address them before they become expensive repairs next season.

The best time for pool closing in our area is typically mid to late October, when water temperatures consistently drop below 60 degrees. This timing prevents algae growth while ensuring you get the most use from your pool during warm fall days. Waiting too long risks freeze damage if we get an early cold snap. Scheduling too early means you might miss out on those beautiful September and early October days when you can still enjoy swimming. We recommend booking your closing by early September to secure your preferred date, as our schedule fills up quickly during peak closing season.
Freeze damage to pool equipment can be expensive and extensive. When water freezes in pipes, pumps, or filters, it expands and can crack housings, split pipes, and damage internal components that cost hundreds or thousands to replace. The most common damage we see includes cracked pump housings, split filter tanks, damaged heater heat exchangers, and burst plumbing lines. A single freeze event can easily cause $2,000-$5,000 in damage. That’s exactly why proper winterization is so important. Our process removes water from all equipment and adds antifreeze where needed to prevent any freeze damage from occurring.
While it’s possible to close your own pool, the process involves more than most homeowners realize. Properly blowing out all plumbing lines requires specialized equipment and knowledge of your pool’s specific plumbing layout. Missing even one water line can result in freeze damage that costs far more than professional closing. We see this frequently – homeowners who thought they drained everything properly but missed a return line or skimmer connection. The cost of professional closing is minimal compared to potential freeze damage repairs. Plus, we handle the heavy lifting of cover installation and ensure everything is done correctly the first time.
A properly installed pool cover should be tight and secure with no sagging areas where water can collect. Safety covers should have all springs attached and tensioned correctly, while solid covers need proper water bags or anchors around the entire perimeter. Loose covers can blow off in winter storms, exposing your pool to debris and allowing water to freeze. We see this happen when covers aren’t anchored properly or when old hardware fails during installation. During our closing service, we inspect all cover hardware and replace anything that’s worn or damaged. We also ensure the cover fits properly and is secured to withstand Long Island’s winter weather conditions.
We add a winterizing chemical kit that includes algaecide, metal sequestrant, and pH adjusters specifically designed for long-term water storage. The exact chemicals depend on your current water chemistry and pool type. Algaecide prevents algae growth during the off-season, while metal sequestrants prevent staining from metals in the water. We also balance pH and alkalinity to prevent corrosion of pool surfaces and equipment. Standard pool chemicals aren’t designed for winter storage and won’t provide the long-term protection your pool needs. We use professional-grade winterizing products that are formulated to keep your water clean and balanced for months.
Yes, we handle winterization for all pool types including inground pools, above-ground pools, and semi-inground installations. Each type requires a slightly different approach, but the fundamentals of proper winterization remain the same. Inground pools typically require more extensive plumbing work to blow out return lines and skimmers. Above-ground pools focus more on equipment removal and proper cover installation to prevent collapse from snow load. Our experience with pool construction and renovation means we understand the specific requirements for each pool type and can customize our winterization process accordingly.
