Pool Winterization Process Merrick

Complete Winterization, Every Single Time

Comprehensive 12-step closing process that covers equipment, chemicals, plumbing, and covers – nothing gets missed. We don’t cut corners because we know what happens when steps get skipped.

First, we balance your water chemistry to prevent corrosion and staining over winter. We use a specific winterization chemical program designed for Long Island’s winter conditions. This typically includes shock treatment to eliminate bacteria and organic matter, algaecide to prevent algae growth during the closed season, and stain prevention chemicals to protect your pool surfaces.

Next comes the critical plumbing work. We blow out every line in your plumbing system to prevent freeze damage. One of the most important steps is blowing out and plugging the lines. If this step is not done, or done improperly, the water in the pipes can freeze and expand over the winter when the ground gets cold, resulting in cracked pipes, cracked skimmers and broken heaters, which are very expensive to replace.

Finally, we properly shut down all equipment and install your cover with correct tensioning and securing. Professional cover installation keeps debris out and prevents safety hazards all winter long. Every piece of removable equipment gets stored properly to extend its life.

Pool winterization includes: Pool water level is first lowered to an appropriate level. Railings and ladders are removed.

When should I schedule my pool closing in Merrick?

The best time for pool closing in Nassau and Suffolk County is typically mid to late October, when nighttime temperatures consistently drop below 50 degrees. You don’t want to close too early and waste swimming time, but you also can’t wait until the first freeze. We recommend scheduling your closing by early October to ensure availability, since this is our busiest time. If you have a pool heater, you might be able to extend the season slightly, but most Long Island pools should be winterized by Halloween to be safe. Most of our customers close the pool in the September to October time frame. The kids are back in school, no one is using the pool, the water is getting chilly, and oh no, here come the leaves. Don’t wait for the first freeze warning. Once temperatures hit freezing, any water left in your plumbing lines can cause expensive damage overnight.

What happens if my pool isn't properly winterized?

Freeze damage happens fast and gets expensive quickly. Water expands when it freezes, so any water left in your plumbing lines, pump, filter, or heater can crack pipes, destroy equipment, and damage your pool structure. We’ve seen single freeze events cause thousands in damage – cracked pump housings, burst plumbing lines, damaged pool surfaces, and destroyed filtration equipment. Even worse, this damage often isn’t visible until spring when you try to open your pool. Insurance typically doesn’t cover freeze damage from improper winterization, so you’re looking at major out-of-pocket repairs. Freezing temperatures can crack pipes, damage equipment, and lead to costly repairs. A poorly closed pool invites debris, algae growth, and dirty water that’s a nightmare to clean in spring. Proper winterization costs a fraction of what freeze damage repairs will run you. Professional closing protects your investment and saves you thousands in potential repairs.

Do you handle both inground and above ground pools?

Yes, we handle complete winterization for both inground and above ground pools throughout Nassau and Suffolk County. The process is different for each type, but both need professional winterization to prevent damage. Inground pools require more complex plumbing blow-outs and equipment winterization, while above ground pools need careful attention to skimmer winterization and proper cover installation. Above ground pools are actually more vulnerable to freeze damage in some ways, since their plumbing and equipment are often more exposed to cold temperatures. Regardless of your pool type, we have the right equipment and experience to winterize it properly for Long Island’s harsh winters. Each pool type has specific vulnerabilities that require different approaches, and we handle both with the same attention to detail and professional standards.

What winterizing chemicals do you use?

We use a specific winterization chemical program designed for Long Island’s winter conditions. This typically includes shock treatment to eliminate bacteria and organic matter, algaecide to prevent algae growth during the closed season, and stain prevention chemicals to protect your pool surfaces. Algae Preventative: Keeps algae at bay all winter long, ensuring a faster and easier spring opening. Chlorine-Free Shock: Protects your pool with safe, effective sanitization that won’t harm pool liners. Algae Preventative: Prevents algae blooms over the winter, so your pool is ready for an effortless spring start. Mineral/Stain Remover: Shields your pool’s surface from staining caused by debris or contaminants sitting on the liner during winter months. All chemicals are included in your service – no surprise charges or additional costs. We use professional-grade products that aren’t available to consumers, ensuring your pool stays protected all winter long.

How much does professional pool closing cost?

Pool closing costs $250 on average, with most homeowners spending between $175 and $300. Expect to spend an average of $175 closing an above ground pool and an average of $300 closing an in-ground pool. The exact cost depends on your pool type, size, and any special features like heaters or water features. Above ground pools are usually smaller with less equipment and fewer accessories. In-ground pools tend to have add-ons that drive up costs, like hot tubs, water features, spa areas, and multiple heaters. Professional winterization costs a few hundred dollars, while fixing winterization mistakes often costs thousands. When you consider that freeze damage can cost $5,000-15,000 in emergency repairs, professional closing is the smart investment. Contact us for a specific quote based on your pool’s needs.

Can I partially winterize my pool myself?

We don’t recommend partial DIY winterization because pool closing is a system – every step depends on the others being done correctly. The most expensive mistakes happen when homeowners try to save money by doing part of the winterization themselves. For example, improper chemical balancing can cause staining and surface damage that costs thousands to repair. Incomplete plumbing blow-out can result in freeze damage that destroys your entire circulation system. Even small mistakes like incorrect water level or improper cover installation can cause major problems. The specialized equipment alone – like commercial air compressors for proper line blow-out – costs more than most homeowners want to invest for once-a-year use. While DIY winterization may seem cheaper, a single mistake can result in costly repairs. Professional technicians use proven methods, specialized tools, and professional-grade winterization chemicals unavailable to consumers. Let us handle the entire process properly the first time.
