The Real Cost of Pool Closing in Nassau County
Nassau County pool owners should expect to pay varying amounts based on their pool type and specific needs. Above-ground pools typically cost around $175 to close, while in-ground pools average $300. However, these baseline costs can fluctuate based on several factors including pool size, equipment complexity, and additional services required.
In Nassau County specifically, homeowners paid between $138.00 and $974.00 for swimming pool maintenance services in 2025, with closing services falling within the lower end of this range for standard procedures.
What’s Actually Included in Professional Pool Closing
Understanding what you’re paying for is crucial when evaluating pool closing services. Pool closing involves several steps: deep cleaning your pool, storing pool accessories and removable equipment, draining water to appropriate levels, adding pool shock and chemicals to balance the water, and winterizing pool equipment like pumps, filters, heaters, and plumbing to prevent freeze damage.
A comprehensive 12-step closing process typically includes:
- Removing all leaves, silt, and debris, followed by thorough vacuuming and wall brushing
- Balancing water chemistry to proper calcium, pH and alkalinity levels
- Adding shock treatment and allowing water to circulate for 24 hours until chlorine levels reach 1.0-3.0 ppm
- Removing drain plugs from pump strainer basket housing, pump volute, filter tank, and pool heater
- Using high-powered air compressors to blow out residual water from plumbing lines and sealing return lines with winterizing plugs
- Installing a properly fitted pool cover, whether mesh safety or solid security type
Why Nassau County’s Climate Demands Professional Winterization
Nassau County’s harsh winter conditions make professional pool closing essential. Long Island winters are particularly challenging, with temperatures dropping fast and staying low, potentially destroying an improperly winterized pool in a single freeze cycle. The optimal timing for pool closing in Nassau County is typically mid to late October when nighttime temperatures consistently drop below 50 degrees, as waiting until the first freeze can cause expensive overnight damage.
Freeze damage happens quickly and gets expensive, as water expands when it freezes, potentially cracking pipes, destroying equipment, and damaging pool structure.
Additional Costs to Consider
Beyond basic closing services, Nassau County pool owners should budget for potential additional expenses:
- Pool covers, which cost between $750 and $2,550 on average
- Pool shocking, which adds between $25 and $50 to your cost
- Hot tub winterization for combination pool and spa systems
- Water feature winterization for pools with additional amenities
- Antifreeze addition for solar heater systems

The Value of Professional Service
Pool winterization represents excellent value due to competition among contractors and the fact that preventive maintenance costs much less than waiting until equipment breaks down. The better you maintain your pool year-round, the more affordable closing will be.
Professional pool closing services offer convenience and peace of mind, typically costing $150 to $300 including chemicals, while most people hire experts rather than attempting DIY approaches, as homeowners often end up doing the job incorrectly and having to hire professionals anyway.
