Winterizing a pool is an essential task for homeowners who want to protect their investment from seasonal damage. The process involves cleaning, draining, and preserving the pool and its equipment to ensure a smooth reopening when warmer weather returns. Yet, one of the most common questions pool owners ask is, “How much does it cost to winterize a pool?” This article will explore the factors that influence winterization costs, offer a cost breakdown, and provide tips to make the process more cost-effective.
Understanding Pool Winterization
Before jumping into costs, it’s important to understand what pool winterization entails. Winterizing, also known as “closing” a pool, is the process of preparing your pool for the winter season. It helps prevent damage from freezing temperatures, algae growth, and wear on equipment.
The primary objectives of pool winterization include:
- Cleaning the water and pool surfaces
- Adjusting the chemical balance to protect equipment and prevent algae growth
- Lowering the water level as needed
- Draining, blowing out, or winterizing pool lines and equipment
- Adding winterizing chemicals and a safety cover
The exact steps and materials required depend on the type of pool (in-ground vs. above-ground), the climate you live in, and whether you’re doing the work yourself or hiring a professional.
Factors That Influence the Cost to Winterize a Pool
Several variables affect how much you’ll spend to properly winterize your pool. Understanding these can help homeowners budget accordingly.
1. Type of Pool
Whether your pool is in-ground or above-ground significantly affects cost. In-ground pools generally require more extensive preparation due to complex plumbing, higher water volume, and the need to protect more expensive features like pool tiles and coping stones.
Above-ground pools are simpler and often quicker to close, which reduces labor and material use.
2. Geographic Location
The climate of your region drives the level of preparation required. In areas with harsh winters like the Northeast or Midwest, complete winterization is necessary to guard against freezing and cracking. Meanwhile, in mild climates like parts of California or Florida, you may opt for a more basic version of winter preparation, which will cost less.
3. Professional vs. DIY
Another main factor in cost is whether you choose to hire a professional or do it yourself. Hiring a licensed pool technician or company ensures proper closure and can extend the lifespan of your pool, but it comes at a higher price.
DIY pool winterization can save money, but it requires:
- Knowledge of pool systems
- Access to the right tools (like a pool cover, winterizing chemicals, and a shop vacuum)
- Physical capability to complete the task
4. Age and Condition of Pool Equipment
Older pools may require more maintenance, extra repairs, or additional attention before closing. In contrast, newer pools with modern filtration systems, heaters, and automatic covers might require a more streamlined process.
5. Additional Services or Upgrades
You may also consider adding services like:
- Installing an automatic pool cover
- Upgrading to a heavy-duty safety cover
- Purchasing winterization kits or premium chemicals
These options boost protection but will also increase the total winterization cost.

Bosco or Leaf Plugs
Bosco plugs are used to seal pool lines and equipment. These plugs can be reusable and cost around $10–$25 per plug.
Winter Chemicals with Stain and Scale Prevention
Some pool experts recommend adding stain and scale inhibitors during closure, especially if your water is hard. These can add $10–$40 to the final bill.
Pool Heater Winterization
If your pool includes a heater (gas or electric), proper winterization might involve draining or winterizing it to prevent frost damage. This typically adds $50–$150 to the process.
How to Save Money on Pool Winterization
If you’re trying to save on costs, it’s still possible to maintain a quality winterization while avoiding unnecessary expenses.
1. Do Your Winterization Each Year
Proper and consistent pool winterization reduces long-term damage and helps avoid hefty repair bills in the spring. Skipping this process or doing it half-heartedly could mean spending more later.
2. Use Reusable Winterization Materials
Instead of buying new plumbing plugs or a new winter cover every year, invest in high-quality reusable materials that can last for 5–10 seasons.
3. Plan Ahead and Buy Supplies Early
Purchasing covers and chemicals before the fall rush begins can often save 10%–20% off seasonal prices. Shop online in late summer or early fall to get the best deals.
4. Maintain Good Water Chemistry Year-Round
Keeping balanced water chemistry helps reduce scale buildup and makes the winterizing process more effective. This step can also reduce the need for extra treatments upon closure.
5. Combine Services with Annual Maintenance
If you’re already hiring someone for fall cleanings or equipment check-ups, consider bundling services to save on labor charges and ensure the process is completed all at once.
DIY Winterization Step-by-Step
For those planning to winterize their pool themselves, here’s a simple guide:
Step 1: Deep Clean the Pool
Remove any debris, brush the walls and floor, and vacuum thoroughly.
Step 2: Test and Balance Water Chemistry
Use a test strip or kit to check pH, chlorine, alkalinity, and calcium hardness levels. The ideal ranges are:
- pH: 7.4–7.6
- Alkalinity: 80–120 ppm
- Calcium hardness: 200–400 ppm (for vinyl pools), 250–600 ppm (for concrete pools)
Step 3: Add Winterizing Chemicals
Use a winterizing algaecide and chlorine tablets. Some pools may require a clarifier or scale preventer depending on the water type.
Step 4: Lower the Water Level
Lower the water to below the skimmer and return jets if you’re in a freezing climate. For areas with mild winters, reducing the level just below the skimmer is enough.
Step 5: Winterize the Pool Equipment
This includes:
- Draining the pump and filter
- Blowing out lines with an air compressor
- Installing winter plugs in the openings
Step 6: Install the Cover Securely
Choose a mesh cover for leaves or a solid cover for safety. Secure it with water bags or anchors to prevent wind from lifting the cover.
Step 7: Add a Pool Cover Pump if Necessary
If you expect significant rain or snow melt, a pool cover pump will keep water from accumulating on the cover and putting pressure on it or the pool.
Choosing the Right Winterization Services
When hiring a professional pool winterizing company, consider the following tips:
1. Research Local Companies
Use online directories and local business listings to find companies. Be sure to check:
- Years in business
- Industry affiliations (e.g. APSP, PHTA)
- Customer reviews
2. Get Detailed Estimates
Ask each company for a written estimate or quote to compare service inclusions. Be wary of unusually low prices—they might mean lower quality or hidden fees.
3. Ask About Warranties or Guarantees
Some companies offer guarantees for their winterization work. For instance, a company might promise to address any damage caused by flawed winterization for free if called promptly in the spring.
4. Ask If They Offer Spring Openings
Some companies offer bundled fall and spring services at a discount. This is ideal if you plan to hire someone regularly for maintenance.
When Is Winterization Not Required?
While most pools benefit from winterization, there are some exceptions:
- Warm climates: In locations like Florida and parts of Southern California where temperatures rarely drop below freezing, pool owners can skip full winterization and switch to low-season maintenance.
- Indoor pools: These typically don’t require seasonal closing, assuming the temperature remains controlled year-round.
- Heated pools: Some homeowners choose to keep their pools open year-round with proper winter chemical maintenance.
If this applies to you, you can skip the closure process—but keep in mind that some basic care is required even during the off-season.
Final Thoughts
In summary, the cost to winterize a pool will largely depend on the pool type, labor approach (DIY vs. professional), location, and equipment needs. You can expect to pay $130–$575 for DIY and $450–$800 for professional services for an average-sized in-ground pool.
By preparing properly, you not only reduce the risk of costly damage but also ensure a faster and easier pool reopening in the spring. Whether you choose to close your pool yourself or hire experts, spending a little now helps protect a significant investment over time.
So before the cold sets in, make sure to give your pool the closure it deserves—and budget accordingly to enjoy the benefits season after season.
What does winterizing a pool involve?
Winterizing a pool is the process of preparing it for the colder months when it won’t be in regular use. This typically involves cleaning the pool, balancing the water chemistry, lowering the water level, draining water from pumps and filters, adding winterizing chemicals, and covering the pool securely. The exact steps depend on whether the pool is in-ground or above-ground and the climate in which it’s located.
For in-ground pools, winter plugs may need to be installed, and automatic safety covers are often used. Above-ground pools might require complete draining or covering with a durable winter cover. The goal is to protect the pool structure and equipment from freezing temperatures, algae growth, and debris accumulation. Proper winterization helps reduce maintenance and repair costs in the spring.
Why is it important to winterize a pool?
Failing to winterize a pool can lead to serious damage due to freezing temperatures. Water left in the plumbing lines or equipment can freeze and expand, causing cracks or expensive damage. Additionally, uncovered pools are susceptible to algae growth, staining, and the accumulation of leaves and debris, making reopening in the spring more difficult and costly.
Winterizing a pool preserves its components and ensures that the pool remains in good condition during the off-season. It also helps maintain water quality, reducing the time and expense required to get the pool ready for swimming again. For pool owners, the cost of winterization is a worthwhile investment compared to the potential repair bills from neglect.
How much does professional pool winterization cost?
The cost of professional pool winterization services typically ranges between $200 and $500, depending on the size and type of the pool. In-ground pools generally cost more to winterize due to the complexity of the equipment and the need for additional winter protection measures. Geographic location and local labor rates will also influence the price.
Some pool service companies may offer package deals that include both opening and closing services, which can reduce the overall cost. It’s important to get a detailed quote from a licensed professional to understand what is included in the service. This ensures the job is done correctly and helps avoid unexpected charges.
What factors affect the cost of winterizing a pool?
Several factors influence the total cost of winterizing a pool, including the pool size, type (in-ground or above-ground), and the condition of the pool and equipment. Larger pools require more time and materials, increasing costs. The need for additional repairs or chemical treatments can also add to the total.
Another major factor is geographic location. Areas with harsh winters may require more extensive winterization measures, while milder climates may need only basic steps. The choice of whether to hire a professional or do it yourself will also significantly impact the cost, as professionals charge for labor, expertise, and equipment handling.
Can I winterize my pool myself to save money?
Yes, it is possible to winterize a pool yourself and save on labor costs, which can range from $100 to $200. DIY pool winterization requires purchasing winterizing chemicals, equipment like air plugs and a winter cover, and following detailed safety and maintenance instructions. Many pool owners successfully complete this task with guidance from pool supply stores or online resources.
However, there are risks involved, especially if you’re unfamiliar with the process. Mistakes such as improper water balance or incorrect winter cover installation can lead to damage or increased costs later. If your pool has a complex system or if you’re unsure about any step, it might be worth hiring a professional to ensure the job is done correctly and safely.
What are the costs of pool winter covers?
Pool winter covers vary in price depending on the type and quality. Solid winter covers, which are recommended for most climates, typically range from $100 to $300 for above-ground pools and $200 to $500 for in-ground pools. Safety covers, which are more durable and provide additional protection, can cost between $300 and $1,000 depending on the size and material.
The type of cover needed will depend on the local climate and the amount of debris in the area. Mesh covers allow water to drain through but offer less protection against dirt and algae. A heavier, solid cover with a tight fit will help keep the pool clean and reduce chemical loss. Investing in a good-quality cover is essential for effective winterization.
What happens if I don’t winterize my pool?
Failing to winterize a pool can lead to costly and extensive damage. Freezing temperatures can cause water in the pipes and equipment to expand, leading to cracked plumbing, broken pumps, or damaged filters. Algae and bacteria can grow in stagnant water, making the pool unclean and hard to recover in the spring.
Additionally, leaves, dirt, and debris can accumulate, potentially staining the pool surface or clogging the system. Repairing these issues can cost significantly more than the price of winterization. Skipping the process may also void warranties on pool equipment or shorten its lifespan, leading to even greater expenses over time. Proper winterization is a small price to pay compared to the potential consequences.
