A fibreglass pool is a great way to upgrade your backyard and turn it into a spot for year-round enjoyment in Ottawa. Known for their smooth finish, fast installation, and low upkeep, fibreglass pools are a solid choice for many homeowners. That said, no pool is completely problem-free. Over time, you might start to notice some issues with the surface. These problems can affect both the pool’s look and its ability to work properly if left untreated.
From blisters under the gel coat to strange stains and hairline cracks, surface damage tends to build slowly. Ottawa’s changing seasons make upkeep even more important here. Cold winters and warm summers can put extra pressure on the materials, especially if your pool hasn’t been inspected or maintained regularly. Knowing what to look for and what steps to take early on can help stop small problems from turning into big expenses.
Identifying Blisters on Fibreglass Pool Surfaces
One surface problem that can catch people off guard is blistering. These small bubbles form underneath the outer layer of the pool shell, usually between the gel coat and the fibreglass itself. At first, they might just look like a few tiny raised spots, but they can multiply and grow if ignored. In some cases, they can even leak and damage the surrounding area.
Blisters form when water seeps between the layers and reacts with chemicals inside the fibreglass surface. You’ll often see these show up near the waterline or in shallow areas that get the most sun. Not taking care of them quickly means they can expand and cause more serious surface separation.
Several things can lead to blistering:
– Problems during the pool manufacturing process
– Long-term exposure to poor water chemistry
– Older, worn-out gel coatings
– Freeze-thaw cycles common in Ottawa winters
– Scratches or damage from cleaning tools or toys
Fixing pool blisters isn’t something that should be put off. While smaller blisters might seem harmless, they usually go deeper than they appear on the surface. Sanding the area and applying a new resin-based coat is a common way to fix light blistering. Heavier damage usually calls for a more detailed repair that might involve draining the pool and resurfacing it.
The best way to prevent blistering is through regular care. Check your pool for early signs of bubbling, pay close attention to water chemistry, and always schedule seasonal inspections. With Ottawa’s climate, small issues can turn bigger quickly, so it’s better to stay ahead of them.
Tackling Discolouration Issues
Another common problem with fibreglass pool surfaces is discolouration. These stains can make your pool look cloudy or patchy, even if the water is clean. The surface might turn shades of brown, yellow, green, or even pink over time, often because of chemical build-up or metals in the water.
Pool stain sources can include:
– High iron or copper levels in the water
– Algae growth that’s worked into the surface
– Sunscreens and lotions left by swimmers
– Incorrect chlorine levels or poor pH balance
– Organic debris like leaves left on the surface
For pool owners in Ottawa, circulation often slows before winter closes in. When not properly maintained, leftover metals or algae can bond with the surface and leave behind tough stains that return in spring.
Thankfully, most surface stains can be cleared. Lighter ones will often fade with the right cleaning product or stain remover. Metal stains usually respond to a metal sequestrant paired with proper pH adjustments. For algae stains, an acid wash may work, but it needs to be done carefully by a trained technician to avoid damaging the finish.
from returning means sticking to a regular cleaning schedule. Vacuum out debris, brush the walls, and test your water often. After the winter thaw, give your pool a thorough check before diving into spring, especially with Ottawa’s lengthy and often unpredictable winters.
Addressing Cracks and Structural Damage
Cracks in your fibreglass pool might start small, but they can lead to bigger trouble if not looked after right away. You might see hairline marks, spider-web shapes, or deep lines. These are usually caused by water pressure changes, ground movement, or damage from freeze-thaw cycles, something Ottawa sees plenty of each year.
Cracks usually happen from:
– Ground shifting or uneven base beneath the pool
– Wear and tear on the gel coat over time
– Sudden changes in temperature
– Heavy objects or pool equipment banging against the surface
It’s tempting to fix minor cracks on your own, but looks can be deceiving. Even the tiniest crack could mean damage below the surface. That’s why a professional inspection is always your best option. Depending on how bad it is, the repair might involve patching, resurfacing, or reinforcing part of the shell.
Minor cracks can often be patched successfully if caught early. Larger damage may require draining the pool or more involved repair work. Once fixed, it’s important to keep your water balanced and avoid placing heavy pressure on weak zones.
Getting the crack looked at quickly is the key. That way, the structure stays solid, and the damage doesn’t spread. It gives you peace of mind heading into swim season.
Maintaining a Smooth Surface
One of the perks of fibreglass pools is the smooth finish. But even smooth surfaces can wear down over time. It could be from chemical imbalances, rough cleaning tools, or just regular use over the years.
Keep the surface smooth and safe with these habits:
1. Rinse pool toys and accessories before use to keep grit out.
2. Always check calcium levels in your water. Low levels can slowly break down the surface.
3. Inspect for chalky or faded spots in the gel coat and take action early.
4. Use soft-bristle brushes and avoid anything abrasive for cleaning.
5. Book a full surface inspection once winter is over to spot rough patches or cracks from the freeze.
In Ottawa, the ground under your pool may swell or tighten with the seasons. That can lead to slight shifts or wear you wouldn’t notice until swimmers start to feel it underfoot. Having a technician check the structure each spring can catch these small issues.
A smooth surface does more than look nice. It cuts down on algae by giving it fewer places to cling to and keeps the water clearer over time. Another bonus is comfort—bare feet prefer a smooth finish.
Staying Ahead of Fibreglass Pool Surface Problems
Caring for your fibreglass pool surface isn’t just about looks. It helps make sure your pool stays safe, clean, and long-lasting. Small steps taken at the right time often mean avoiding bigger costs later.
The extremes of Ottawa’s climate mean pool care really needs to match each season. Give your pool a solid check in spring after the snow and ice melt. Stay alert during warm months, and as fall hits, prep your surfaces before it gets too cold. This routine will help your pool last through it all.
Looking out for things like surface bubbling, stains, cracks, or rough patches means better swim seasons and fewer unexpected problems. Partnering with an expert can make those repairs less stressful and help keep your pool in prime shape.
