Pool closing costs are a key consideration for homeowners preparing for winter. Most pool closing costs range from $200 to $500, with most spending $350. Factors such as pool size, type, and service level affect your final price. Investing in professional closing helps protect your pool and avoid expensive repairs.
Several elements play a role in determining your total pool closing cost. Understanding these factors helps you plan and budget for the best results.
The type of pool you own is one of the most significant factors impacting closing costs:
In-ground pools cost more to close than above-ground pools due to their size, plumbing complexity, and features.
Saltwater pools and pools with attached spas or custom features may require extra steps and materials, increasing the price.
Standard pool closing services for both types include draining lines, cleaning, chemical balancing, equipment winterization, and cover installation.
| Pool Type | Description | Average Closing Cost | 
|---|---|---|
| In-ground | Large, built-in pools with a full plumbing system | $250–$500 | 
| Above-ground | Smaller, surface-level pools with a simpler setup | $150–$300 | 
| Saltwater | Pools using saltwater generators | $250–$550 | 
| Spa-attached | Pools with integrated spa features | $350–$600 | 
| Custom features | Pools with waterfalls, fountains, or lighting | $300–$650 | 
The size of your pool—length, width, and depth—directly affects the closing cost. Larger pools require more chemicals, longer labor times, and additional materials. Complex shapes or extra-deep pools can also increase the price due to the added effort needed for thorough cleaning and line draining.
| Pool Size | Description | Average Closing Cost | 
|---|---|---|
| Small | Up to 15,000 gallons | $150–$250 | 
| Medium | 15,000 to 30,000 gallons | $250–$400 | 
| Large | Over 30,000 gallons | $400–$600 | 
Most homeowners close their pool once a year, in the fall before freezing weather. Signing up for a recurring service contract can lower your per-visit cost compared to a one-time service.
If your climate requires closing the pool more than once a year or you use your pool year-round, this can increase your total annual expense. Areas with harsh winters may see higher demand and prices during peak closing season.
Every professional pool closing requires specific materials, including winterizing chemicals, antifreeze for plumbing, plugs, and a pool cover.
The cost of materials depends on your choices—mesh covers are less expensive than solid safety covers, and premium winter chemicals can raise your total. Optional upgrades, such as winterizing kits or custom covers, can also affect your budget.
| Material Type | Description | Cost Range | 
|---|---|---|
| Chemicals | Balancing, shock, algaecide | $30–$70 | 
| Antifreeze | For plumbing lines, it prevents freeze damage | $10–$30 | 
| Plugs and gizmos | Seals return lines, skimmers | $5–$20 each | 
| Pool cover | Mesh, solid, or safety cover | $80–$600 | 
| Winterizing kit | A combination of chemicals and tools | $40–$100 | 
Pool service technicians, specialty companies, or a skilled handyman often perform pool closing. Labor is charged either as a flat fee or hourly, with rates averaging $75 to $125 per hour.
Labor costs are higher in areas with a short pool season or high demand. The service includes draining or blowing out lines, applying chemicals, winterizing all equipment, and installing the cover. Pools that are difficult to access or have complex features may incur higher labor fees.
Where you live has a major influence on the cost of closing your pool. Regions with colder climates tend to have higher costs due to the need for more thorough winterization.
Urban areas may charge more than rural ones, reflecting higher labor rates and transportation costs. The length of your pool season and accessibility of your backyard also play a role—tight spaces or difficult terrain can add to your closing bill.
Tipping your pool closing professional is not required, but it is a thoughtful gesture for quality service or complex jobs. A standard tip is $20 to $50 per technician, or 10% of your total bill. Consider tipping more for exceptional service, challenging pool layouts, or if you use the same company year after year.
Pool closing is best done once per year, often in the fall, before outdoor temperatures drop below freezing. The ideal timing depends on your region—northern states may need to close pools in September, while southern areas can wait until late October or even November. Closing too early can lead to algae growth, while waiting too long risks freeze damage.
Signs your pool is ready for closing include water temperatures dropping below 65°F, decreased use, and falling leaves. Seasonal surcharges may apply if you book late or need an emergency closing after a sudden freeze.
Many pool closing services offer optional add-ons for a more thorough or convenient process. These extras can help protect your pool or save you time, but they come with additional costs.
| Add-On Service | Description | Cost Range | 
|---|---|---|
| Pool cover installation | Installing or removing a cover (if not included) | $50–$150 | 
| Spa or water feature closing | Winterizing attached spas or water features | $75–$200 | 
| Equipment storage | Storing ladders, diving boards, and accessories | $30–$75 | 
| Cleaning or vacuuming | Deep cleaning before closing | $50–$120 | 
| Additional chemicals | Extra shock, algaecide, specialty treatments | $20–$60 | 
| Antifreeze for lines | Protects plumbing from freezing | $10–$30 | 
| Leak detection/repairs | Finding and fixing minor leaks | $100–$400 | 
| Travel fees | For remote or hard-to-reach locations | $25–$75 | 
Closing your pool yourself can reduce costs, but it comes with tradeoffs. DIY pool closing expenses include chemicals ($30 to $70), antifreeze ($10 to $30), plugs and equipment ($20 to $60), and possibly tool rental. Expect to spend $70 to $200 in total if you already own a basic cover and tools.
DIY closing requires time, skill, and careful attention to your closing checklist. Mistakes—such as not fully draining lines or improper chemical balance—can lead to freeze damage or void warranties, resulting in higher repair costs later.
For pools with complex plumbing, attached spas, or custom features, hiring a local pool pro is the best way to ensure all winterization steps are handled safely.
| Method | Average Cost | 
|---|---|
| DIY | $70–$200 | 
| Pro | $200–$500 |
