5 Clear Signs It’s Time to Renovate or Remodel Your Old Swimming Pool
A custom swimming pool is the crown jewel of any San Antonio backyard—a private oasis where you can escape the intense summer heat, entertain family and friends, and unwind after a long day. However, just like the roof over your head or the engine in your car, your swimming pool experiences wear and tear over time. The combination of shifting Texas soils, harsh UV rays, and years of chemical exposure eventually takes its toll on even the most beautifully constructed pools.
While regular maintenance and minor repairs can keep your pool functioning for years, there comes a point when a simple patch job is no longer enough. You might find yourself constantly paying for quick fixes, battling algae blooms due to poor circulation, or simply looking out your window at a backyard that feels stuck in a previous decade.
If your pool is no longer the pristine, inviting sanctuary it once was, a full renovation might be the most cost-effective and rewarding solution. Remodeling your pool doesn’t just fix underlying structural and mechanical issues; it offers a blank canvas to completely reimagine your outdoor living space.
But how do you know when it is time to stop repairing and start remodeling? Here are the 5 clear signs it is time to renovate your old swimming pool with Keith Zars Pools.
- Visible Structural Deterioration: Rough Plaster, Cracks, and Leaks
The most undeniable sign that your pool is crying out for a renovation is visible physical damage to the interior surface. In the San Antonio and South Central Texas climate, gunite pools are incredibly durable, but the plaster finish that waterproofs and protects the concrete shell does not last forever. Depending on water chemistry maintenance and usage, a standard pool finish typically lasts between 10 and 15 years before it begins to degrade.
What to Look For:
- Delamination and Pitting: If the plaster at the bottom of your pool feels rough like sandpaper—or worse, if it is peeling or flaking off in chunks—the finish has failed. Not only is this uncomfortable for swimmers’ feet, but it also creates micro-crevices where stubborn algae can take root, making it incredibly difficult to keep your water balanced and clear.
- Structural Cracks: Hairline cracks in the plaster are normal over time, but larger, deep cracks that seem to grow are a major red flag. Texas is notorious for expansive clay soils that swell when wet and shrink during droughts. This shifting can put immense pressure on an older pool shell.
- Unexplained Water Loss: Due to our hot Texas summers, evaporation is expected. However, if you are losing more than a quarter-inch of water a day or constantly having to run the hose to keep the water level up, you likely have a leak.
The Renovation Solution:
A pool remodel addresses these issues at their core. Gunite pool resurfacing involves chipping out the old, failing plaster and applying a brand-new interior finish. Today, homeowners have access to premium aggregate finishes like pebble or quartz, which are exponentially more durable, stain-resistant, and visually stunning than traditional white plaster. Furthermore, during a renovation, experts can diagnose and permanently repair structural leaks and reinforce the shell, ensuring your pool remains watertight for decades to come.
- Outdated, Cracked, or Missing Pool Tile and Coping
The waterline tile and the coping (the cap on the edge of the pool that transitions to the deck) serve both aesthetic and functional purposes. They protect the pool shell from water penetration at the surface line and provide a safe, smooth grip for swimmers. When these elements start to fail, the entire pool looks neglected.
What to Look For:
- Missing or Hollow Tiles: Over time, the grout and thin-set holding your waterline tile in place will degrade. If tiles are falling into the pool, or if they sound hollow when you tap them, water has breached the barrier.
- Cracked and Crumbling Coping: Brick or basic concrete coping from the 1990s or early 2000s can become brittle, crack, or separate from the pool shell. This creates sharp, dangerous edges that are hazardous for bare feet and hands.
- Aesthetic Fatigue: Even if the tile is structurally sound, styles change. Glass block, outdated tropical motifs, or faded, chalky tiles can make your entire backyard look like a relic of the past, significantly detracting from your home’s luxury appeal.
The Renovation Solution:
Updating the tile and coping is one of the most visually transformative aspects of a pool remodel. Ripping out dated materials and replacing them with modern, luxury options instantly elevates the space. Homeowners are increasingly opting for premium natural stone coping, such as travertine or limestone, paired with iridescent glass mosaic waterline tiles. These modern materials not only look breathtaking as they reflect the Texas sun, but they are also designed to withstand extreme temperature fluctuations without cracking.
- Inefficient, Loud, or Frequently Breaking Pool Equipment
A swimming pool is only as good as its plumbing and mechanical systems. The pump, filter, and heater are the “heart and lungs” of your pool. If your equipment pad looks like an antique exhibit, sounds like a jet engine, or requires a service technician to visit every other month, a remodel is highly recommended.
What to Look For:
- Sky-High Energy Bills: Older single-speed pool pumps run at one maximum speed all the time. They are massive energy hogs, often accounting for a significant portion of your summer electricity bill in San Antonio.
- Constant Repairs: If you are continually repairing old heaters, replacing valves, or fighting poor water circulation that leads to cloudy water, the cost of these band-aid fixes will eventually exceed the cost of upgrading.
- Manual Operation: Are you still walking out to the equipment pad in the dark to turn valves manually just to turn on the spa or the pool heater?
The Renovation Solution:
A massive benefit of a pool remodel is the opportunity to modernize your mechanical system. Upgrading to a variable-speed pool pump can reduce your pool-related energy costs by up to 80%, as these pumps can run at lower, energy-efficient speeds to maintain perfect circulation.
Furthermore, remodeling allows you to integrate Smart Pool Technology. Modern pool automation systems allow you to control everything—water temperature, lighting colors, pump speeds, and water features—directly from an app on your smartphone. Imagine turning on your spa heater from your phone while leaving a restaurant, so the water is perfectly warm by the time you arrive home.
- Your Lifestyle and Family Needs Have Changed
The pool you built or inherited when you bought your home might have been perfect for your lifestyle 15 years ago, but families evolve. Perhaps your children were toddlers when the pool was built, and you prioritized a large shallow end. Now, they are teenagers who want to play water volleyball. Or maybe the kids have moved out, and you want to transform your family play pool into a sophisticated, adult-focused entertainment and relaxation space.
What to Look For:
- Underutilization: You simply aren’t using the pool as much as you used to because it doesn’t serve your current lifestyle.
- Missing Luxury Features: You visit resorts or friends’ homes and find yourself wishing you had a built-in spa, a tanning ledge, or a swim-up bar.
- Accessibility Concerns: As homeowners age, stepping down a steep, narrow ladder into the pool can become difficult.
The Renovation Solution:
A comprehensive remodel isn’t just about changing the surface; it’s about changing the shape and function of the pool. During a renovation, a custom pool builder like Keith Zars Pools can completely reconfigure the layout.
- Add a Baja Ledge (Sun Shelf): We can pour new concrete inside the existing shell to create a shallow, 6-inch-deep lounging ledge, perfect for placing in-water lounge chairs or providing a safe splash area for grandchildren.
- Build an Attached Custom Spa: If your original pool was “pool-only,” a remodel can include the addition of a raised custom spa with an elegant spillover water feature.
- Integrate Custom Features: Additions like sheer descent waterfalls, deck jets, or integrated fire bowls can completely alter the ambiance, turning a basic swimming hole into a luxury resort experience.
- The Overall Aesthetics No Longer Match Your Home
Your home is your largest investment, and over the years, you have likely updated the interior. You may have remodeled the kitchen, modernized the bathrooms, and painted the exterior. But if you haven’t touched the backyard, a glaring disconnect forms between the beautiful, modern interior of your home and the tired, dated exterior.
What to Look For:
- Washed-Out Decking: Old, stained, or cracked concrete or Kool Deck makes the entire backyard look neglected.
- Lack of Outdoor Living Synergy: The pool feels like an isolated rectangle in the grass rather than an integrated part of an outdoor living space.
- Poor Lighting: Basic incandescent pool lights do nothing to highlight the beauty of your yard at night.
The Renovation Solution:
A pool remodel should be viewed as a holistic backyard transformation. It is the perfect time to upgrade your pool decking. Replacing cracked concrete with elegant travertine pavers, stamped concrete, or natural stone creates a seamless, high-end transition from your back door to the water’s edge.
Additionally, a renovation is the ideal time to add color-changing LED pool lighting, which consumes a fraction of the power of old halogen bulbs and creates a vibrant, customizable nighttime atmosphere. By tying the pool remodel in with new landscaping, perhaps an outdoor kitchen or a custom pergola, you elevate your entire property.
