Winterising your fibreglass pool is crucial to keep it in top condition. Failing to protect your pool during the cold months can lead to significant damage. Damage can include cracks, leaks, and expensive repairs. By taking the right steps, you can prevent these issues and ensure your pool is ready for use when warm weather returns.

In this article, we will explain the importance of winterising your fibreglass pool. We’ll cover potential damages that can occur if you neglect winter protection. This blog will also provide you with a step-by-step guide to properly winterise your pool. From cleaning and balancing the water to covering and securing your pool, we’ve got you covered. Follow these tips to keep your pool safe and sound throughout the winter season.

Why Winterising Your Fibreglass Pool is Crucial

Winterising your fibreglass pool is essential to keep it in great condition. Freezing temperatures can cause severe damage to your pool’s structure. Water that gets into small cracks or seams can freeze, expand, and cause the pool shell to crack. Additionally, unprotected pipes and equipment can freeze and burst, leading to costly repairs.

Maintaining water quality is another important reason to winterize your pool. Without proper care, your pool can become a breeding ground for algae. Debris can also accumulate a lot over the winter months without a cover. This makes spring cleaning a hassle and can also cause long-term damage to your pool's surface. Keeping the chemical balance right during winter helps to prevent these issues. Proper winterisation includes adding the right chemicals to keep the water clean and safe to swim in.

Taking the time to winterise your fibreglass pool ensures it stays in great shape. It prevents expensive damage and makes it easier to reopen in the spring. Don’t skip this essential maintenance step!

Tools and Materials Needed for Winterising

Winterising your fibreglass pool properly requires some essential tools and materials. Below is a list of all the essentials you need to protect your pool:

  • Pool Cover 
  • Air Compressor
  • Winterising Chemicals (e.g., chlorine, algaecide, pool antifreeze)
  • Pool Pillows
  • Skimmer Guards
  • Pool Brush
  • Leaf Net or Skimmer
  • Water Test Kit
  • Pool Pump and Filter (for final cleaning before closing)
  • Submersible Pump (to remove excess water from the cover)
  • Pool Vacuum
  • Plugs and Caps (for pipes and fittings)
  • Pool Heater (if applicable)
  • Water Hose
  • Goggles and Gloves (for handling chemicals safely)

First, you'll need a sturdy pool cover to keep out debris and protect the water quality. At Starlight, we can install an enclosure or cover to protect your pool all year round. They not only protect during the winter months but also provide complete UV protection during summer.

An air compressor is necessary to blow out the water from your pipes and equipment. Doing this can prevent potential freeze damage. Chemicals, like chlorine, algaecide, and pool antifreeze are key to keep the water clean throughout the winter months.

In addition to these basics, other tools can make the process easier and more effective. Pool pillows can be placed under the cover to prevent it from sagging and accumulating snow and ice. Skimmer guards are also important. They protect your skimmers from cracking due to ice formation.

Safety is key when winterising your pool. Wear gloves and goggles when handling chemicals to protect your skin and eyes. Ensure all electrical equipment is turned off before you start the winterizing process to avoid any accidents.

Using the right tools and materials can save you time and money. They prevent damage and keep your pool in great shape. 

Step-by-Step Guide to Protecting Your Fibreglass Pool in Winter

Clean and Balance the Pool Water 

The first step to winterizing your fibreglass pool is cleaning it thoroughly. Start by skimming off leaves, insects, and any debris from the water surface. Use a pool vacuum to clean the bottom of the pool. Don’t forget to brush the pool walls to remove any algae or dirt clinging to the surfaces.

Once the pool is clean, it’s crucial to balance the pool chemicals. Test the water’s pH, alkalinity, and calcium hardness using a water test kit. Ensure that the pH level is between 7.2 and 7.6. Add the necessary chemicals to adjust the levels as needed. Balanced water prevents algae growth and protects the pool's surface and equipment.

Lower the Water Level 

Next, you’ll need to lower the pool water level. Drain the water until it’s below the skimmer and return lines. You can do this using a submersible pump or the pool’s filtration system. Typically, you should lower the water level about 4-6 inches below the skimmer opening.

Adjusting the water level prevents freezing water from damaging the pool’s plumbing. It also ensures that the pool cover fits properly. A properly fitting cover provides better protection throughout the winter.

Drain and Protect Pool Equipment 

Draining your pool equipment is a vital step in the winterising process. Start by turning off the pool’s pump and filter system. Drain the water from the pump, filter, heater, and any other pool equipment. This prevents water from freezing inside the equipment, which can cause serious damage.

Store your equipment safely in a dry, sheltered area. Make sure to cover it to protect against dust and debris. If you have removable plugs and caps, use them to seal off the pipes and fittings. This extra step helps to keep your equipment in good condition for the next swimming season.

Add Winterising Chemicals 

Adding winterising chemicals is essential for maintaining water quality during the off-season. Use a winter algaecide to prevent algae growth. You should also add a pool antifreeze to the plumbing lines. This is vital if you live in an area that experiences freezing temperatures.

Follow the manufacturer’s instructions for the correct dosage and application methods. Pour the chemicals into different areas of the pool to ensure even distribution. These chemicals help keep your pool water clear and prevent damage to the pool surfaces and equipment.

Covering the Pool 

Finally, use a high-quality pool cover to cover your pool. Choose a cover that fits your pool’s dimensions and is designed for winter protection. Solid covers are effective at keeping debris out, while mesh covers allow water to drain through.

Once you’ve placed the cover over the pool, secure it tightly. Use water bags, weights, or other securing methods recommended by the cover manufacturer. Adding pool pillows underneath the cover helps to prevent the cover from sagging and reduces the risk of ice damage.

By following these steps, you can protect your fibreglass pool from winter damage, ensuring it’s ready for use when warmer weather returns.

Common Mistakes to Avoid When Winterising

Winterising your fibreglass pool is crucial to maintaining its longevity. It means it'll be ready for use when warmer weather returns. Below are some common mistakes that can undermine your efforts:

Not Balancing the Pool Water Properly 

One of the most common mistakes is not balancing the pool water before closing it for winter. If the water's pH, alkalinity, and calcium hardness levels are off, it can lead to corrosion or scale build-up. Unbalanced water can also promote algae growth. Algae can make your pool harder to clean come spring. Always test and adjust the water chemistry before winterizing.

Using an Incorrect Pool Cover 

Another mistake is using the wrong type of pool cover. Not all covers offer the same level of protection. A flimsy or ill-fitting cover can let debris into the pool or allow water to accumulate, causing damage. Invest in a high-quality cover designed for winter use, and ensure it fits your pool snugly to provide optimal protection.

Failing to Protect Pool Equipment 

Pool equipment, like pumps, filters, and heaters, needs to be drained and stored correctly. Leaving water in these components can cause them to freeze and crack during cold weather. Make sure to drain all the water and store your equipment in a dry, sheltered area. Use pool antifreeze in the plumbing lines if you live in a region with freezing temperatures.

Ignoring the Need for Periodic Checks During Winter 

Many people forget that even a winterized pool needs occasional checks. Failing to inspect your pool cover and water level throughout the winter can lead to problems. Heavy snowfall or wind can displace the cover, and water levels can change. Regularly check your pool to ensure everything remains secure and intact.

By avoiding these common mistakes, you can protect your fibreglass pool from winter damage. These will also ensure it’s in great shape for the next swimming season. If you need assistance, Starlight Pools is always here to help with expert advice and services.
