Here's How We Protect Your Investment

First, we balance your water chemistry to prevent corrosion and staining during the off-season. This isn’t just adding a few chemicals—it’s precise testing and adjustment based on your specific pool and water conditions.

Next, we drain your equipment and plumbing lines completely. Any water left behind becomes ice that splits pipes and cracks fittings. We use compressed air to blow out every line, ensuring nothing’s left to freeze.

Finally, we install your winter cover properly. Not just thrown over the top, but secured with the right tension and support to handle snow loads and wind without tearing or sagging into the water.

The ideal time for pool closing in South Hempstead is typically late September through early October, before nighttime temperatures consistently drop below 50°F. You don’t want to wait until the first freeze warning—that’s too late. Nassau County’s weather can be unpredictable, with sudden temperature drops that catch pool owners off guard. We recommend scheduling your closing by mid-September to ensure availability during our busy season. Early closing also gives you time to address any equipment issues we discover during the winterization process, rather than leaving problems to worsen over winter.
Improperly closed pools face expensive damage from freeze-thaw cycles common in Nassau County winters. Water left in plumbing lines expands when frozen, cracking pipes and splitting fittings that cost thousands to repair. Pool surfaces can stain permanently from unbalanced water chemistry sitting stagnant for months. Equipment like pumps, filters, and heaters can crack internally if not properly drained and winterized. You might also face algae blooms and water quality issues that require extensive chemical treatment and cleaning before your pool is swimmable again. Professional closing prevents all these costly problems.
Yes, we provide professional closing services for all pool types in South Hempstead—inground gunite pools, fiberglass pools, vinyl liner pools, and above ground pools. Each type requires specific winterization techniques. Above ground pools need different chemical treatment and equipment handling than inground pools. The plumbing configurations vary, and cover systems are completely different. Our experience with pool construction and design means we understand the unique requirements of each pool type and can customize our closing process accordingly.
Our pool cover installation includes proper fitting, securing, and tensioning of your winter cover or safety cover. We don’t just throw a cover over your pool—we ensure it’s installed to withstand Nassau County’s winter weather. For standard winter covers, we use water bags or cover clips to secure the edges and prevent wind damage. We check for proper water level to support the cover without over-stretching. Safety cover installation involves anchoring the cover to deck anchors with proper spring tension. We inspect all hardware and replace any worn components to ensure your cover performs correctly all winter.
Absolutely. We specialize in winterizing complex pool systems including gas heaters, heat pumps, salt water generators, and full automation systems. These components require specific winterization procedures that many homeowners don’t know. Heaters need internal water drained and specific antifreeze protection. Salt systems require cell removal and proper storage. Automation systems need programming adjustments for winter mode. Our experience with pool construction means we understand how these systems integrate and what’s needed to protect each component through Long Island’s winter freeze-thaw cycles.
Pool closing costs vary based on your pool size, equipment complexity, and specific winterization needs. Basic inground pool closing typically ranges from $200-400, while pools with extensive equipment or safety covers cost more. The investment pays for itself by preventing freeze damage that can cost thousands in spring repairs. A cracked pool heater alone can cost $1,500-3,000 to replace. We provide upfront pricing with no hidden fees. Contact us for a specific quote based on your pool’s requirements and equipment setup.
