A swimming pool is one of the most enjoyable and luxurious features a homeowner can have—but no pool lasts forever in its original condition. Over the years, pools deteriorate, equipment becomes outdated, and once-beautiful finishes become eyesores. Whether you own a plaster, pebble, vinyl liner, or fiberglass pool, there comes a time when maintenance is no longer enough—and a complete renovation is the best path forward.
In this comprehensive guide, we’ll explore the most critical signs that indicate it’s time to renovate your swimming pool, focusing on four primary areas:
Structural damage and leaks
Outdated or malfunctioning equipment
Safety hazards
Aesthetic deterioration
Understanding these indicators will help you make a confident, informed decision about when to invest in a renovation—and how to extend the life, beauty, and functionality of your pool.
1. Structural Damage: Cracks, Leaks, and Surface Failures
Concrete Pools (Plaster or Pebble Finishes)
Concrete pools are durable, but over time, they can develop structural issues. One of the first and most obvious signs is cracking. These may start as hairline surface cracks in the plaster finish, but deeper cracks can form in the concrete shell due to shifting ground, water pressure, or aging materials. If left unaddressed, they may lead to leaks, which can erode the soil around your pool and compromise its foundation.
Peeling or flaking plaster (spalling), rust stains from exposed rebar, and hollow spots that sound different when tapped are additional red flags. Pools showing any of these symptoms need a full resurfacing to restore the integrity of the finish and prevent further damage.
Vinyl Liner Pools
Vinyl liners typically last 7–12 years, depending on the level of exposure and care. Key signs that your liner needs replacing include:
Tears, cracks, or leaks
Faded colors and patterns
Wrinkles, sagging, or separation from the coping track
Stretched or brittle material
If patching no longer solves the problem—or if your liner has faded to the point that it’s no longer attractive—a replacement is the most effective long-term solution.
Fiberglass Pools
Fiberglass pools have a smooth, gel-coated surface that can last 20 years or more—but even they aren’t immune to structural decline. Look out for:
Spider cracks or “crazing”
Blisters (osmosis bubbles) in the gelcoat
Surface chalking or fading
Cracks near fittings, lights, or steps
Blistering and worn gelcoat are signs that water has penetrated the outer shell, and the pool needs resurfacing. Please don’t wait for these problems to expand, as they can compromise the structure and lead to long-term issues.
2. Outdated or Failing Pool Equipment
While surface issues are often visible, equipment problems tend to fly under the radar until they impact your enjoyment—or your utility bill. Modern pool renovations typically include upgrading core systems, such as the pump, filter, heater, and automation.
Frequent Repairs
If you’re regularly calling your pool tech to fix the pump, heater, or filter, your equipment may be at the end of its service life. Continual repairs are not only costly—they’re a sign that it’s more economical and efficient to replace aging components during a renovation.
High Energy Costs
Older equipment—especially single-speed pumps and electric heaters—is notorious energy hogs. If your energy bills have increased without an apparent reason, your pool system may be to blame.
Modern variable-speed pumps can reduce energy use by up to 70%, while energy-efficient heaters and LED lighting can significantly impact long-term operating costs.
Poor Water Circulation or Clarity
Are you struggling with murky water, algae, or difficulty balancing chemicals? Poor circulation caused by aging pumps or ineffective filters can make maintaining clean, safe water nearly impossible.
If your system is undersized, clogged, or simply outdated, a renovation is the perfect opportunity to install a properly sized, high-performance setup.
Technology Limitations
Today’s pools offer features such as automation, remote controls, smartphone integration, and saltwater chlorination. If your current pool doesn’t support these options, a renovation can bring your pool into the 21st century with more innovative, safer, and more convenient operation.
3. Safety Hazards: Renovate Before an Accident Happens
Nothing is more important than safety—especially if children or elderly individuals use your pool. Renovations can address serious issues that may otherwise go unnoticed.
Outdated Main Drains and Suction Covers
Pools built before the Virginia Graeme Baker Pool & Spa Safety Act (2008) may have dangerous main drains that pose an entrapment risk. Replacing these with anti-vortex, VGB-compliant covers is essential for swimmer safety.
Broken or Sharp Tile and Coping
Missing, loose, or jagged tiles and coping stones can cause injuries. Renovation provides the opportunity to replace broken components with new, slip-resistant, and safer materials that reduce the risk of falls or cuts.
Slippery or Rough Surfaces
An aging plaster surface can become abrasive, and old vinyl liners may lose texture and become slick. Both conditions can cause slips or scrapes.
During renovation, you can apply new surface finishes—like pebble, quartz, or smooth fiberglass gelcoat—to create a safe, comfortable, and non-abrasive swimming environment.
Poor Lighting
Dim, broken, or nonfunctional pool lights create nighttime hazards. A renovation allows you to install modern LED lighting, which is not only energy-efficient but also enhances visibility and safety after dark.
Lack of Safety Features
If your pool lacks fencing, a pool alarm, or a compliant cover, now is the right time to add these life-saving features during a renovation. Pools that are visually appealing but lack adequate safety measures are a recipe for disaster. Renovation can provide both form and function.
4. Aesthetic Deterioration: When It Just Looks Old
While safety and structure are paramount, there’s also the simple issue of appearance. A dated, faded, or unattractive pool can ruin the atmosphere of your backyard.
Faded or Stained Surfaces
In plaster and pebble pools, years of chemical exposure and sun will cause colors to fade and stains to set in. If scrubbing, acid washing, or chemical treatments no longer improve the look of your pool, resurfacing is your only long-term solution.
Vinyl liners can also stain, stretch, or fade to the point of being beyond repair. Once patterns are no longer visible or the liner loses its snug fit, both aesthetics and functionality suffer.
Fiberglass pools may develop chalky surfaces, fading, and discoloration, which signal that the gelcoat is failing. Renovation restores vibrancy and cleanliness to the finish.
Tile and Coping Wear
Old, cracked, missing, or simply outdated waterline tile can make even a functional pool look neglected. Modern pool tile offers fresh colors, mosaics, and non-slip options that instantly give your pool a facelift.
The same applies to coping: replacing old stone or concrete coping with a new style can significantly alter the look and feel of your pool.
Outdated Design
Does your pool still scream 1980s? Features like deep diving ends, square steps, or dated colors might not suit modern tastes or your family’s current needs. Renovating allows you to reshape the pool, add a tanning ledge, spa, or water features, and completely modernize the experience.
Why Renovating Your Pool is Worth It
A swimming pool renovation is a significant investment, but it offers big returns:
Extend the pool’s life by 15–30 more years
Improve safety for your family and guests
Lower energy and chemical usage
Fix nagging issues once and for all
Enhance curb appeal and property value
Make the pool feel like new again
Most importantly, you’ll feel better about using and enjoying your pool every day. Renovation turns a frustrating or aging pool into a clean, efficient, beautiful, and safe oasis.
Renovate When the Signs Are Clear
If your pool is showing signs of wear—like structural cracks, persistent leaks, outdated equipment, fading surfaces, or safety concerns—it’s time to start planning a renovation. Addressing these issues promptly not only enhances the look and feel of your pool but also extends its lifespan, boosts energy efficiency, and improves safety for everyone who uses it.
Before you begin any renovation, it’s essential to identify or locate hidden leaks that could compromise your investment. A leak left unaddressed can lead to continued water loss, structural erosion, or expensive setbacks down the line. That’s why leak detection should always be your first step.
