The Best Liners for Pools

Are you looking for liners for pools in London, Ontario? Whether you are building a new pool or need to replace an existing liner, a wide variety of options are available. From vinyl pool liners to fibreglass, there is a range of materials and designs that can meet your needs. Let’s look at the different types of pool liners available and what you should consider when choosing the best liner for your pool. But first, let’s discuss pools that don’t have liners.

Concrete Pools (Gunite Pools)

Most custom pools, with or without liners, are constructed with a steel frame followed by a concrete surface. Instead of covering it with a liner, the concrete remains exposed or covered with decorative finishes. However, concrete pool resurfacing must be built into the maintenance budget for this pool. Because concrete is porous, they stain easily especially when water chemistry is not balanced. To repair, they must be drained and washed or resurfaced.

In addition to the need for concrete pool resurfacing and the potential for using more chemicals, the surface can be very abrasive or rough. This will be rough on your feet and not as comfortable for swimmers as pools with liners. In addition, pools without liners can be tough on cleaning equipment. Automatic pool cleaners wear out much quicker.

So what options are available for pool liners?

Types of liners for pools

You have a variety of swimming pool liners available to choose from depending on the pool’s shape and size. Most commonly, pools are lined with a standard vinyl liner. Alternatively, you can choose a fibreglass liner.

Vinyl Liners

As an alternative to leaving a concrete or gunite pool exposed or decoratively surfaced, vinyl inground pool liners cover the pool walls and floor with seamed sheets of vinyl. These provide an easy-to-clean, durable and decorative surface. Pool owners choose vinyl liners for their affordability upfront and flexibility. However, most vinyl liners should be replaced at least every 10 years. Similarly, an exposed concrete pool should be resurfaced just as often.

Fibreglass Liners

Fibreglass is a great choice because it’s extremely durable. It can withstand wear and tear better than other types of liners. However, you must select from pre-designed moulds limiting any customization.

Factors to consider when choosing a pool liner

You need to consider factors like climate, durability, customization, maintenance costs, and liner installation budget when choosing liners for pools.

Climate

First, consider the climate when choosing a pool liner. Different climates require different liners to stand up to the elements. In London, Ontario, the climate tends to be humid in the summer and cold in the winter, so it is important to choose a liner that will not crack or tear because of extreme temperatures.

Durability

Consider how often you plan to use the pool, how you plan to sanitize your water, and what will be behind the liner. If you will use the pool often or intend to swim with pets, you want to choose a durable liner that can stand up to frequent use and claws. Otherwise, you may get away with a more economical option.

Sanitizing with salt won’t damage a fibreglass liner. But can put vinyl pool liners on top of metal wall panels at risk for corrosion.

Customization

The size and shape of the pool should also be taken into consideration when selecting a liner. If you want a custom shape or size, you need a custom-made liner in order to ensure a good fit.

Also, consider the colour and pattern of the liner. Not only can the right colour and pattern give your pool a beautiful aesthetic, but certain patterns can also help hide dirt and debris that accumulates in the water over time. See what options you have to select from for vinyl versus fibreglass to help make your decision.

Maintenance Costs

Both vinyl and fibreglass liners for pools provide smooth, easy-to-clean surfaces, but chemical needs vary between the two. Always be sure to test the chemistry of your pool water and maintain alkalinity, pH, calcium and chlorine to swim safely no matter what style of liner you choose. Both require significantly lower energy costs than concrete pools without a liner.

Installation Budget

Overall, your initial investment will be cheaper if you select a vinyl liner, but you need to budget for more frequent pool liner replacements.

How to know when it’s time to replace a pool liner

No matter what type of liner you choose, it’s important to remember that all liners should be replaced at some point. Pool builders like Cracknell can help you determine if you should replace your liner based on the type and condition of the liner.

A well-maintained liner can last up to 10 years, but extreme weather, excess use, and lack of proper maintenance can all lead to a shorter lifespan. The average according to our research is between 5 and 9 years. Here are some signs that it may be time to replace the liner in your inground pool:

Discolouration or fading

Sunlight and exposure to chemicals can cause pool liners to fade or discolour over time. If you notice a difference in the colour of your liner compared to when you first installed it, it might be time for a replacement.

Tears and punctures

If you notice any tears or punctures in your pool liner, don’t wait too long to replace it. Small holes can become bigger over time and could even lead to a leak.

Loose seams

If you notice any of the seams around the edges of your pool liner becoming loose, it’s likely time to replace the liner. If left unchecked, this could lead to more severe damage in the future.

Staining or build-up

Exposure to certain chemicals can cause staining or buildup on your pool liner, which can weaken its integrity. If this happens, consider replacing the liner sooner rather than later.

Leaks

If you believe water levels decrease faster than expected with just evaporation, pressure test your lines and inspect the liner for signs that may indicate potential leaks.

How to install a pool liner

You must ensure you install a pool liner properly to prevent water leakage and costly repairs in the future. Here are the steps you should take when installing a new pool liner:

Before installing the pool liner, it is important to ensure that the pool walls and bottom have been properly cleaned and prepared. This includes removing any objects that may damage or puncture the pool liner, as well as using a vacuum to remove debris and dirt from the bottom and sides of the pool. If the concrete beneath your vinyl liner looks damaged, concrete pool resurfacing may need to be considered.

Next, measure the inside walls and floor of your pool to determine what size and shape of a liner you need. Measure accurately, as even small miscalculations can lead to problems with fitting the liner into the pool.

Start by placing the bottom part of the liner in the pool, making sure that it is flat on the bottom. Next, attach one side of the liner to the pool wall and then attach the remaining three sides. Be sure to pull tight as you go, so that no wrinkles appear in the liner.

When all four sides are attached to the pool wall, use a heavy-duty stapler to secure them in place. Make sure you do not over-staple, as this can cause punctures or tears in the liner. Once all four sides have been secured, fill in any gaps with foam or rubber insulation tape.

Finally, fill up the pool with water and make sure that all seams and edges are sealed properly. Then check for any leaks or tears and repair as needed.

By following these steps, you can install your pool liner correctly and ensure that your pool remains leak-free and looks great.
