For many Brisbane homeowners, a swimming pool is part of the home’s identity. It’s where summers are spent, birthdays are celebrated, and weekends unwind. But like any part of a property exposed to weather, water, and time, pools age. After 20 to 30 years, even well-built concrete pools begin to show signs that they need attention.
A well-planned pool renovation is not just about appearance. It’s about structural integrity, safety, efficiency, and ensuring your outdoor space continues to suit your lifestyle.
Here’s what to look for, and what you should know before renovating.
Why Older Concrete Pools Start to Deteriorate
Concrete pools are durable, but they are not immune to wear. Over time, several factors contribute to deterioration:
1. Structural Movement
Ground movement, soil conditions, and natural settling can lead to cracks in the shell or surrounding areas. Even small cracks can eventually lead to leaks or surface damage.
2. Surface Erosion
Marble, plaster, or pebble finishes slowly wear down from chemical exposure and constant water contact. Rough textures, staining, and patchy discolouration are common signs that resurfacing may be required.
3. Outdated Design
Pools built decades ago often have dated tiles, coping, or surrounding pavers. While structurally sound, they may not match modern outdoor design trends or current safety standards.
4. Efficiency Issues
Older filtration systems and plumbing setups are often less energy-efficient. Renovation can be an opportunity to upgrade pumps, filtration, and water circulation systems.
Renovation vs Replacement: What Makes Sense?
Many homeowners wonder whether to demolish and rebuild or restore what’s already there. In most cases, renovation is the more practical solution.
Renovation typically:
- Preserves the existing pool structure
- Reduces construction time
- Minimises disruption to landscaping
- Is more cost-effective than a full rebuild
Unless the structural shell is severely compromised, restoring and upgrading an existing pool can deliver modern results without starting from scratch.
What a Pool Renovation Can Include
Renovation projects vary widely depending on the condition of the pool and the owner’s goals. Common upgrades include:
Resurfacing
Resurfacing replaces the interior finish of the pool. Marble finishes remain popular for their durability and classic appearance, particularly in concrete pools. A new surface improves comfort underfoot and restores water clarity and colour.
Re-Tiling
Waterline tiles often show the earliest signs of age due to chemical exposure and sun bleaching. Updating tiles can instantly modernise the look of a pool.
Coping and Surround Upgrades
The area around the pool is just as important as the pool itself. Renovation can include replacing coping, updating pavers, or redesigning the pool surround to better connect with patios and gardens.
Structural Repairs
Crack repairs, leak detection, and reinforcement work ensure the pool remains safe and watertight.
Equipment Modernisation
New pumps, filters, and chlorination systems can significantly improve efficiency and reduce long-term operating costs.
Renovating Pools With Limited Access
One challenge many property owners face—particularly in established suburbs—is limited site access. Not every pool is easily accessible to heavy machinery. Experienced renovation teams often use specialised techniques to complete complex projects without damaging existing landscaping or structures.
This is especially relevant in dense residential areas or properties built on sloped blocks, where logistics can be more demanding than the renovation itself.
How Long Does Renovation Take?
Timeframes depend on the scope of work. Minor resurfacing may take a couple of weeks, while more extensive structural or design upgrades can take longer.
Key stages usually include:
- Drainage and surface preparation
- Structural repairs (if required)
- Surface application and curing
- Tiling or surround updates
- Refill, balancing, and final inspection
Weather conditions in Southeast Queensland can also influence timing, particularly during the wetter months.
Signs You Shouldn’t Ignore
If you notice any of the following, it may be time to assess your pool’s condition:
- Persistent water loss
- Rough or flaking interior surfaces
- Hollow-sounding areas in the shell
- Cracked tiles or lifting coping
- Rust stains or visible reinforcing steel
- Frequent chemical imbalance issues
Addressing small problems early can prevent more extensive structural damage later.
Designing for the Next 20 Years
Renovation is also an opportunity to rethink how the pool fits into your lifestyle today. Families with young children may prioritise safety features and shallow entries. Empty nesters may focus on low-maintenance finishes and entertaining areas. Lighting upgrades, integrated seating, and subtle aesthetic improvements can dramatically change how the space feels.
A thoughtful renovation balances durability with design, ensuring the pool remains both functional and visually cohesive with the rest of the property.
The Value of Experience in Pool Restoration
Not all pool work is the same. Renovation requires a different skill set than new construction. Understanding older construction methods, diagnosing structural issues, and applying long-lasting finishes takes specialised knowledge built over time.
For homeowners considering a pool renovation, working with experienced professionals ensures that surface upgrades are supported by proper structural preparation—something that ultimately determines how well the renovation holds up in the years ahead.
