How Do I Start Preparing to Close My Inground Fiberglass Pool?

Posted on September 19, 2018June 16, 2025 by riley

When temperatures consistently fall below 65 degrees, it’s time to host the final pool parties of the season and start preparing to close your fiberglass pool. Preparing adequately for closing ensures a smooth transition into winter and a more effortless spring opening. To put your best foot forward, observe the following pool maintenance tasks to check off your list before winter.

Schedule Your Closing Date

Timing is crucial when it comes to pool closing. Contact your pool service company early to schedule a closing date. Taking a proactive approach to saving the date will help ensure you secure a spot before the busy closing season begins. Consider scheduling based on your climate and coordinate the date with other seasonal tasks to maximize efficiency. In colder climates, close the pool consistently before temperatures drop below freezing, typically between late September and mid-October. You may push closing to late October or early November in milder climates. If you live in an area with lots of falling leaves, you might want to close the pool earlier or use a cover to prevent debris buildup.

Properly balanced water will reduce the likelihood of algae growth and ensure cleaner water when you reopen the pool next year. Fiberglass pools are more algae-resistant than other types, thanks to their non-porous, smooth surface, which makes it harder for algae to attach and grow. However, if conditions are favorable, algae can still develop over winter, even in fiberglass pools. A stain and scale preventative product should also be added to protect the fiberglass surface during the off-season. When preparing for winterization:

Adjust the pH to a level between 7.2 and 7.4.
Adjust the alkalinity to 80 to 120 ppm.
Adjust the calcium hardness to below 120 ppm.
Add an algaecide according to product instructions.
Add stain and scale remover per product instructions.

Pool supply stores offer winterization kits that often include everything you need, including algaecide and stain and scale preventatives. However, many pool owners enlist the help of a professional service to test their chemistry, adjust the water’s chemical levels, and complete other winter pool maintenance tasks.

Gather Your Equipment

Take the time to inspect all necessary winterization equipment, including winter plugs, skimmers, and maintenance tools. For easy access, items should be stored in one location, such as a garage or shed, to minimize time spent searching for tools. It’s also a great time to inspect all the equipment you’ll use upon opening your pool in the spring. If anything needs repair or replacing, handle it before closing so it won’t hinder your ability to enjoy your pool when the swim season comes around again.

Clean the Pool Thoroughly

Before closing your pool, it’s important to clean it thoroughly. Vacuum the pool to remove dirt and debris, scrub the water line, and backwash the filter (or remove and clean the cartridge filter if you have one). A clean pool is vital for closing as it will help you and the professionals enjoy a smoother closing process. It will also ensure the water is cleaner when you open next season.

Invest in a Quality Pool Cover

A reliable winter pool cover will help maintain the integrity of your pool during the off-season. Some pool cover options include:

Solid Vinyl Covers with a Pump System: These covers are popular for winterizing because they are highly effective at blocking sunlight and preventing algae growth. They keep out debris and water. Look for covers with a built-in pump system to remove accumulated water on top.
Mesh Safety Covers: Mesh safety covers are durable and allow rainwater and melted snow to drain through, which can be convenient. However, they let some sunlight through, so they’re not ideal in areas prone to algae. If you choose a mesh cover, opt for one with tightly woven mesh to limit light exposure as much as possible.
Hybrid Covers: These combine the benefits of solid and mesh covers, providing more durability and sunlight blocking while allowing water to drain. They can be an excellent compromise for easy maintenance while reducing algae risk.
Winter Covers with Air Pillows (for Freezing Climates): Air pillows placed under a solid or hybrid cover help prevent ice from damaging the pool walls by relieving pressure from expanding ice. This combination is especially beneficial if you live in a colder climate with freezing winters.
Automatic Pool Covers: Automatic pool covers are durable, secure, and easy to use, providing a tight seal that keeps out sunlight and debris. They provide convenient year-round protection, are more expensive, and require a power source. However, they make checking your water levels and chemistry easier during the winter months and provide nearly instant safety in any season.

Store Pool Accessories Properly

Gather and clean all pool toys, floats, and accessories as you prepare to close. Deflate rafts and thoroughly wash them before storing them in a dry location, such as a garage or pool house. Additionally, according to manufacturer or pool professional advice, protect your diving board, slide, handrails, and ladders. For unremovable items, consider applying a protective wax for winter storage.

Safely Store Chemicals

Store any unused pool chemicals securely and safely to prevent accidents. It’s important to ensure that all chemical containers are tightly sealed to avoid leaks and spills. Store these containers in a well-ventilated area, away from heat sources such as furnaces or direct sunlight, as excessive heat can compromise the integrity of the chemicals. Additionally, store different types of chemicals separately. For instance, keep chlorine and shock treatments away from acids to prevent dangerous reactions. Consider organizing your chemicals by categorizing them, labeling each container clearly, and maintaining an inventory to track what you have. This organized approach enhances safety and makes it easier to find the chemicals.

Cherish the Days

As you prepare to tuck your pool away for winter, take a moment to look back on the memories you made this season. From lazy afternoons and lively pool parties to quiet swims at sunset, every splash holds a story worth sharing. Why not revisit the photos and videos you’ve captured, reliving those sun-soaked days. Let the anticipation of next season build, knowing that your winterizing preparations set the stage for more unforgettable poolside moments when warmer days return.

The Hidden Costs of Installing an Inground Pool

Posted on September 18, 2018June 16, 2025 by riley

Installing an inground pool can transform your backyard into a personal oasis, offering a perfect relaxation, exercise, and entertainment spot. While upfront inground pool costs might seem manageable, there are numerous hidden costs that potential pool owners must consider. Understanding these hidden expenses for inground pools will help you make an informed decision and avoid unexpected financial burdens.

Initial Installation Costs

The initial installation is the most apparent cost. The process of installing an inground pool includes excavation, pool shell, plumbing, electrical work, and landscaping. The price varies significantly based on the pool type (concrete, vinyl, or fiberglass), size, and additional features like waterfalls or lighting. The installation can range from $25,000 to $120,000 on average, but this is just the beginning. Typically, vinyl inground pools are the cheapest way to build an inground pool when it comes to upfront installation costs. Fiberglass would follow next, and then concrete is typically the most expensive. It’s also important to note that these cost estimations are assuming the pool is installed by a professional pool builder. DIY inground pool costs may be less upfront, but if done incorrectly, it could cost you much more down the line to correct mistakes.

Excavation and Site Preparation: Before the pool installation, the builder must prepare the site. Site preparation involves excavation, which can be more complicated and expensive depending on your soil type, the presence of rocks, or any necessary grading. Unexpected obstacles during excavation can add a significant amount to the cost. Additionally, permits and inspections required by local authorities also add to the initial expenses.

Pool Shell and Materials: The choice of materials for your pool shell—concrete, vinyl, or fiberglass—impacts the overall cost. Each material has pros and cons, with concrete being the most durable, customizable, and expensive. Vinyl liners are the cheaper option in upfront expenses, but liners need replacement every 5-10 years on average. Fiberglass is a mid-range option in terms of cost and durability.

Maintenance Costs

Regardless of what material your pool is made of, regular maintenance is essential to keep it in good condition. Maintenance costs include chemical balancing, cleaning, equipment upkeep, and potential repairs. Required maintenance will also depend on your pool’s material. For example, concrete pools often require acid washing and replastering after a specific time, adding to your lifetime upkeep expenses.

Water Balance Treatments: Maintaining the correct chemical balance in your pool is essential for health and safety. The cost of chemicals such as chlorine, pH balancers, and algaecides can add up over time. Pool owners should expect to spend several hundred dollars annually on chemicals. Follow the recommended water chemistry levels per your pool’s manufacturer.

Cleaning and Repairs: Regular cleaning is necessary to keep your pool free of debris and algae. Whether you do it yourself or hire a pool service, maintaining an inground pool involves ongoing costs. Pool equipment such as pumps, filters, and vacuums also require maintenance and eventual replacement. Additionally, unexpected repairs due to equipment failure or structural issues can be costly.

Utility Costs: Pools consume a significant amount of water and electricity. Filling a pool the first time requires a large volume of water, and ongoing evaporation means you must top it off regularly. Refilling can be expensive, whether due to evaporation, leaks, or kids splashing. Water can be a significant cost, particularly in areas with high water prices or restrictions on water usage. The cost of running pool pumps, heaters, and lighting can significantly increase your utility bills, especially if you run them frequently. Pool heaters alone, particularly gas or electric models, consume a lot of energy. Efficient equipment and smart usage can help manage these costs, but they remain a substantial part of pool ownership. Electric use will likely cost you hundreds of dollars annually.

Winterization: In colder climates, pools require winterization to protect them from freezing temperatures. This process may involve draining the pool partially, adding antifreeze to the plumbing, and covering the pool securely. Please note: a fiberglass pool’s water level is NOT to be lowered for winterization, which could cause potential structural damage. Winterization and reopening in the spring come with labor and materials costs.

Insurance and Liability: Homeowners should consider the impact of an inground pool on their home insurance. Pools are often regarded as attractive nuisances and can increase liability risks. As a result, insurance premiums can rise significantly. Adding safety features such as fencing and pool alarms can mitigate some of these costs but are also an additional ongoing expense.

Other Considerations

Long-term Resale Value: While a pool can enhance your enjoyment of your home, its impact on resale value is mixed. In some markets, a pool can increase the appeal and value of a home, while in others, it can be a deterrent due to the associated maintenance costs and liability concerns. Potential homebuyers may also be wary of the hidden costs of owning a pool.

Legal and Regulatory Considerations: Local regulations may require specific safety measures such as fencing, alarms, or particular cover types. Ensuring compliance with these regulations may involve additional costs for installation and potential modifications. Be sure to discuss the local requirements for your pool with the pool builder who is installing it.

The Bottom Line of Inground Pool Costs

Inground pool installation comes with many costs you may not initially think about. Understanding these hidden costs allows you to make a more informed decision and enjoy your pool without unexpected expenses.

6 Tips to Reduce Inground Pool Operating Costs

Posted on June 28, 2018June 16, 2025 by Karen

Buyers often only look at upfront costs when pricing and comparing inground pools. However, ongoing pool operating costs can add up over the lifetime ownership of your pool. While all pool types have some of the same expenses, understanding the differences in operating costs among fiberglass, vinyl liner, and gunite pools can help you make smarter choices to keep the costs in check. From testing your water chemistry to maintaining equipment, check out our tips on reducing your inground pool costs.

Tip 1: Test Your Pool Water Regularly

According to HomeGuide, annual pool chemical costs average $175 for a fiberglass pool, $400 for a vinyl pool, and $750 for a concrete pool. However, your actual cost will depend on the amount of chemicals you need to maintain balanced water chemistry. Trying to correct problems after you have “lost your pool” can result in extra, unnecessary expense, so test often to help maintain better control. Regularly test your water using a DIY test kit, take a sample to a pool store, or use a professional pool service for a more thorough analysis. In addition to the usual pH and chlorine levels, professionals assess a wider range of factors, such as alkalinity, calcium hardness, and stabilizer levels, ensuring that any imbalance is detected before it becomes a costly problem.

Tip 2: Add Chemicals in the Evening

To get the most out of your pool chemicals, regardless of pool type, add them in the evening or at night when the sun is down. Adding pool chemicals in the evening is ideal for all pool types to help ensure that they work optimally, extending their efficacy and reducing the frequency of reapplication. Chemicals like chlorine degrade quickly under sunlight, so evening application allows them to work overnight without UV interference, ensuring better absorption and balanced water. This timing also improves the overall effectiveness of algaecides, pH adjusters, and other treatments, keeping your pool water clear and properly maintained.

TIP 3: Keep Your Pool Clean

When you regularly backwash, skim, brush, vacuum, and monitor your pressure gauge, you’re less likely to have prematurely expensive repairs. Fiberglass pools are more algae-resistant than other pool types, so you’ll automatically save time and money on cleaning. Maintaining a clean pool improves the efficiency of your pool’s filtration system, reducing wear and tear on equipment. Costs for pump replacements, filter repairs, and other common issues vary depending on the pool type and equipment brand. Considering all pool types, HomeGuide estimates that replacing a pool pump motor averages $150 to $800, and repairing it costs $50 to $300. A new inground pool filter costs $385 to $1,600. Repairing minor issues in your heater or heating tubes can cost $100 to $300, and replacing your heater averages $1,600 to 5,200. Set reminders or regularly schedule cleaning to save money in the long run.

TIP 4: Save Water by Managing Usage and Covering Your Pool

Water conservation is a critical aspect of reducing inground pool operating costs. During the swim season, pools require refills as they lose water due to evaporation, improper backwashing, and kids splashing. On average, pools lose about two inches of water per week, up to around 2,000 gallons per month. Depending on local water rates, this ongoing cost can range from $4 to $20 monthly. Pool covers can dramatically reduce evaporation by up to 90%. They also help maintain your pool’s temperature, lowering heating costs. Monitor splashing and limit it by setting clear rules for pool play. Not only does this save water, but it also reduces the need to add and rebalance your pool’s chemicals. Follow the manufacturer’s guidelines for filter backwashing to avoid unnecessary water loss.

TIP 5: Heat Your Water More Efficiently

Heating your pool can be one of the most significant ongoing expenses, so it’s important to manage it wisely. Fiberglass pools retain heat better than other pool types due to their insulating properties, making them more energy-efficient and less costly to heat. Electric resistance heaters consume a lot of electricity, with operating costs ranging from $175 to $600 per month. Gas pool heaters quickly warm up the water, but they average between $200 to $500 or more per month to run. On the other hand, heat pumps are much more energy-efficient, costing about $50 to $150 per month, though they take longer to heat the water. Solar pool heaters use electricity only to circulate water, making them the most cost-effective at around $10 to $25 per month. Regardless of your pool heater type, set your pool heater between 78-82 degrees to maintain a comfortable temperature without overworking the heater.

TIP 6: Save Energy 3 Ways

Your pool pump plays a vital role in water circulation and filtration, so efficiently running it can save money. Consider switching to a variable-speed pump, which uses less energy than a single-speed pump and allows you to adjust the flow rate based on your pool’s needs. A timer can automatically control when the pump runs, optimizing usage during off-peak hours to reduce energy consumption. This simple addition can significantly cut down your electric bills. It’s easy to forget to turn off your pool lights, especially after an evening swim. Unfortunately, keeping the lights on when the pool isn’t in use can unnecessarily add to your electricity costs. Make it a habit to check that all lights are off before heading inside for the night. Accidentally leaving the backwash running or overfilling your pool wastes water and incurs additional heating and chemical balancing costs. Set reminders or timers when performing these tasks to avoid costly errors.
