As a homeowner, you’re probably well aware that your home-sweet-home will need – or perhaps already has had – some amount of renovation or major work (such as roof replacement) to keep it comfortably habitable. However, the same is true for your swimming pool. Over the years, pools experience wear-and-tear that needs to be addressed. Knowing how to recognize the signs of an aging pool can help you make timely repairs and renovations so that you, your family and friends can enjoy many more years of fun!
Pool Surface and Finish Issues
As you might assume, age affects concrete, fiberglass and vinyl liner pools differently. Here’s a breakdown of conditions to watch out for. Our thanks to Summerhill Pools, Alliance Pools & Patios and Total Tech Pools & Leisure for their expertise!
Concrete pools:
Surface stains – Stains that won’t clean off, especially those caused by algae, rust, or minerals are a major indicator.
Peeling or flaking plaster – If the plaster is flaking or peeling, it’s a clear sign that the surface is deteriorating and needs attention.
Rough texture – A rough or uneven texture on the pool surface can indicate wear and tear and the need for resurfacing.
Cracks in the pool surface – Visible cracks may or may not indicate problems, depending upon their cause and location. However, they do require monitoring for any changes that indicate prompt attention is needed. Our blog post – “Are Plaster Cracks in Your Concrete Pool Cause for Alarm?” – covers this topic in detail.
Discoloration – This can be caused by various factors, including algae, rust and minerals, and can indicate that the surface is in need of repair or resurfacing.
Rust stains – Rust stains, especially if they are persistent and difficult to remove, can be a sign that the pool’s surface is deteriorating and needs resurfacing.
Corroded tile grout – If the grout is wearing away or looks corroded, your pool may need resurfacing.
Chalky residue – Chalky residue on the pool surface can be a sign that the plaster is deteriorating and needs to be resurfaced.
Unexplained drop in water level – If you are losing more water than usual, there might be cracks or leaks in the surface. Call us immediately to detect the location of the leak.
Fiberglass pools:
Osmosis – Commonly known as blistering, the pool’s surface becomes bumpy or blistered when contaminated water travels back towards it from the surrounding soil. The pool’s integrity may be compromised by osmosis bubbles over time, causing small leaks.
Cracks – fiberglass pools are prone to cracks of all kinds, especially when they’re old. However, there are times when these cracks are not visible and do not extend beyond the gel coating. An inferior quality pool may crack more easily, compromising structural integrity and causing leaks.
Chalking – Several factors contribute to the chalking of fiberglass pools, such as age and excessive chlorine. It occurs during the oxidation of the gel coat on the pool. Inhaling or inadvertently drinking topcoat flakes from the pool water while swimming can cause digestive and respiratory problems.
Black stains and spots – These are a clear indication that you should resurface the pool. Small or large, these black spots in the gel coat can range from tiny pinheads to large openings with dark fading lines.
Color deterioration – Fiberglass pools typically become color-distorted with age and continued sun exposure. A white and sometimes flaky pool surface results when the color in the topcoat fades. In some cases, the top gel coat may degrade due to color distortion, resulting in granulating and chalky topcoats.
Vinyl liner pools:
Cracking and tearing – Vinyl liners will deteriorate over time, due to exposure to pool chemicals and the sun’s UV rays. Inspect your liner regularly for cracking or tears, which can be symptomatic of bigger problems (like water leakage). If you find cracks, monitor the water level for one to two weeks. If the water level drops by more than one inch, you’re likely dealing with one or more leaks. As vinyl ages it becomes brittle, which means a patch will no longer bond to it.
Fading and staining – A liner will fade over time as it ages and is exposed to chemicals and UV rays. Watch for significant rust stains or algae buildups, as they can be difficult (if not impossible) to remove. Also, as liners fade, so too do their patterns. Homeowners looking to replace their pool’s liners are often looking to both brighten up their pool and update its design.
Wrinkling, slipping and stretching – Over time, vinyl liners will lose some of their plasticity and elasticity. You might notice the liner beads in several areas or slips out of the track, symptoms that it’s stretching too much. You should also keep your eye out for loose fittings around the pool’s return jets and skimmer.
Leaking – If you can find the leak, you might be able to patch it and get a few more seasons out of the liner. If you can’t find it, however, you’ll need to replace your pool’s liner. Failing to do so can cause seeping water to corrode your pool’s walls and wash away the sand beneath, creating dangerous sink holes.
Pool Equipment and Plumbing Issues
As the good people at Griffin Pools & Spas state the situation, “Aging pool equipment and plumbing can be a major concern for pool owners. As the years go by, the components that keep your pool running smoothly can start to deteriorate, leading to costly repairs and potentially even safety hazards. ‘A well-maintained pool is like a well-maintained car,’ says a pool expert. ‘If you don’t take care of the engine, it’s going to break down eventually.’
“Some common signs of aging pool equipment and plumbing include worn-out seals, corroded pipes, and faulty valves. These issues can cause leaks, water loss, and even pool collapses. If you notice any of these signs, it’s time to consider a pool renovation. A professional inspection can help identify the extent of the damage and determine the best course of action.
“Regular maintenance can help extend the life of your pool equipment and plumbing, but eventually, renovations may be necessary. By staying on top of repairs and upgrades, you can ensure your pool remains safe and enjoyable for years to come.”
Our blog post – “Your Guide to Pool Equipment Maintenance” – provides step-by-step instructions for maintaining the pool pump, pool filter and automatic pool cleaner.
Pool Deck and Surroundings Issues
Signs your pool deck is aging include cracks, chipping, discoloration, fading, algae/mold growth, uneven surfaces and loose or rotted materials – all of which can indicate the need for repair or resurfacing. Again, evidence of pool deck aging depends upon the type of material used.
Concrete pool decks:
Cracks – Small cracks can expand and lead to structural issues, especially if water seeps in and causes damage to the underlying soil.
Chipping and flaking – This indicates the surface is deteriorating and may be a safety hazard.
Discoloration and stains – Sunlight, pool chemicals, and algae can cause fading and staining, making the deck look worn.
Uneven surfaces – Settling or ground movement can cause the deck to become uneven, creating tripping hazards.
Algae and mold growth – These can make the deck slippery and unsightly, and can also indicate moisture problems.
Paint peeling or erosion – If the paint on the deck is peeling or eroding, it’s a sign that the surface is deteriorating.
Wooden decks:
Cracked or splintered boards – This is a sign that the wood is drying out and cracking, and that the deck is no longer structurally sound.
Warped or buckled boards – This indicates that the wood has been exposed to moisture and is deteriorating.
Loose or rotted posts and railings – These are signs that the deck is becoming unstable and unsafe.
Fading and discoloration – Sunlight and weather can cause wood to fade and discolor, making it look unappealing.
Mold and mildew growth – These can indicate moisture problems and can also be a health hazard.
General signs of an aging pool deck:
Water pooling – If water is pooling on the deck after a rain, it could indicate a problem with drainage or a slope issue.
Wobbly or loose railings – This is a sign that the deck is becoming unstable and unsafe.
Rusty or loose connectors – These are signs that the deck is not being properly maintained and that the materials are deteriorating.
