How To Care For Your Fibreglass Swimming Pool In Winter


Winter is just around the corner, and our beloved fibreglass pools need a little TLC during the cooler months. 

Winter pool care isn’t just about preventing a chilly surprise when you take a spontaneous plunge – it’s also about ensuring your fibreglass pool stands the test of time, staying beautiful year after year. 

So, grab your pool net, and let’s chat about how to keep your backyard oasis gleaming while keeping those fibreglass plunge pool costs in check. Let’s make sure your pool stays as beautiful as ever, even when the temperatures drop.

Pre-Winter Preparation

Before you kick back and enjoy a hot cuppa, it’s time to get your fibreglass swimming pool in tip-top shape for the winter. Getting a jump start on your winter care routine can make all the difference.

First things first, grab your cleaning supplies and clean up. Remove leaves, debris, and insects with a pool net, or it may become a breeding ground for algae. 

Here’s a pro tip from expert pool builders: balancing your pool water’s pH and chemical levels is the secret sauce for maintenance. It ensures your pool stays crystal clear and inviting, even when the skies are grey. 

Maintaining Water Levels

Rain, sun, and the occasional Aussie breeze can all play a part in wear and tear. 

Fluctuating water levels can have a bigger impact on fibreglass pools than you might think. Too much rain increases water levels and subsequent evaporation drains the pool. This rising and falling can strain your pool’s structure and equipment, leading to costly repairs down the line.

Here are some maintenance tips:

  • Keep an eye on the water levels to make sure they don’t drop below the recommended range.
  • Top up your pool with a hose when the water level is low.
  • Invest in a high-quality pool cover to prevent evaporation and flooding.

Whether you have a fibreglass above-ground pool or a fibreglass inground pool, these steps are essential.

Winter Chemical Treatment

As the mercury drops, your pool doesn’t get a vacation from chemical care. In fact, you might need to show your fibreglass plunge pool some extra love.

Winer chemical treatments can prevent algae and bacteria from making a cozy home in your pool. 

  • Chlorine: Keep chlorine levels maintained during the winter, even if you aren’t swimming in the pool.
  • pH balance: Adjust the pH to between 7.2 and 7.6.
  • Algaecides and winterising chemicals: Keep your pool free of algae and bacteria with specialised winter chemical blends.

Close care is essential–you don’t want to add extra plunge pool prices when spring comes around and you need to do a huge clean.

Pool Equipment Maintenance

Your pool equipment also needs some TLC to brave the winter chill. When building a pool, it’s likely that you added some extras to keep maintenance easy, like pumps, heaters, or even jets.

Firstly, drain the water from your pool equipment to prevent freezing and damage. Then, give it a thorough clean to ensure the filters, pumps, and heaters are free of debris and gunk. Inspect for wear and tear while you’re at it. 

You’ll want to keep your pump running through winter to keep the pool clean. However, you can reduce its usage to about four hours per day. 

Store any equipment that you’re not using indoors, or use covers to keep frost at bay. Finally, ensure that you inspect your outdoor equipment regularly. Equipment and tools for a fibreglass pool cost money to replace, so it’s worth protecting them. The early bird catches the worm, so make sure you give them a quick lookover every so often.

Pool Cover Usage

A high-quality cover is like a cozy winter blanket for your pool. It’s a gamechanger for fibreglass inground pools, and fortunately, there are plenty of options that won’t break the bank. Many covers for a plunge pool cost under $1000, with plenty of great options for around $500.

A cover keeps your pool free from debris, leaves, and unwanted visitors like insects. Plus, it minimises water loss and warmth if you have a heated pool. Safety-wise, it’s a win, too, reducing the risk of accidents if you have little ones or pets.

You can choose from many different options, including:

  • Mesh: Keeps out debris while allowing rainwater to pass through.
  • Solid: A solid sheet of material that keeps your pool spotless while preventing evaporation and trapping heat.
  • Automatic: A convenient solution that covers the pool with minimal effort, providing insulation and safety.

When you install swimming pool covers, you need to do so properly. Here’s how:

  1. Measure: Get a cover that fits your pool snugly, ensuring a perfect fit.
  2. Secure: When you unroll the cover, make sure it’s evenly spread.
  3. Fasten: Secure the cover in place with anchors or straps.
  4. Tighten: Keep the cover taught to prevent debris from settling on top.

Periodic Checks and Cleaning

When your fibreglass plunge pool is all ready for winter, your job isn’t done. You still need to check it, but thankfully, you can do so with a simple routine. 

  • Regularly check the water clarity and chemical balance to ensure everything is swimming along smoothly. A quick peek every now and then will help you spot and address any issues before they become major headaches.
  • Ensure the pool cover is free from damage and and debris to stop it from sinking in. Also, check for wear and tear – a stitch in time saves nine!
  • If you check your pool and find some algae build-up, give it a quick brush. In fact, an occasional brush can keep algae at bay to maintain the pool’s pristine appearance. 

These simple steps will ensure that your fibreglass pool installation remains in top-notch condition.

Preparing for Spring

As the sunshine makes its return, it’s time to prep your fibreglass lap pool for a refreshing dip. Here’s how:

  1. Sweep away debris and give the pool a thorough clean. Skim the surface, clean the floor, and clean out the filters.
  2. Consider a shock treatment to deal with any lingering contaminants.
  3. Check the chemical balance and make any necessary adjustments to the pH and chlorine.
  4. Inspect your pumps and filters, and ensure everything is in working order. Switch everything on and let it run to clear out the pool.

With a little preparation, you can get fibreglass plunge pools in order before swimming season kicks off.

Wrapping up: Keeping Your Pool Clean Through Winter

In short, it’s easy to keep your pool pristine through the colder months. All you need to do is start early with your prep to clean thoroughly, balance the chemicals, and clean out your equipment for proper storage. Invest in a cover to shield the pool from debris, then conduct regular checks to keep it spick and span.

No matter what your fibreglass pool design, it’s important to maintain it and keep it in check so that your garden can be the oasis you’ve always dreamed of.
