Big gardens are one of the best things about living in Constantia. They are also hard on a pool. Oak leaves, pine needles and winter rain all end up in the water, and an older marbelite finish slowly turns rough, stained and porous. Fibreglass pool relining gives that same concrete shell a new, smooth surface without digging out the pool.
Our team relines concrete, gunite and marbelite pools across Constantia and the nearby Southern Suburbs. Below we explain what the work involves, how long it takes and how to tell if your pool is ready for it.
Why fibreglass pool relining suits Constantia gardens
Many Constantia homes sit on large, established plots with mature trees close to the pool. Leaves drop into the water for most of the year. On worn marbelite, that organic matter stains the surface and gives algae plenty of rough texture to cling to.
A fibreglass lining changes this. It is a reinforced fibreglass layer finished with a gelcoat, and the result is smooth and non-porous. Algae has less to grip, so the pool usually needs fewer chemicals and less brushing than tired marbelite. For a busy household with a big garden to look after, that saving in weekly effort adds up.

Signs a Constantia pool needs pool relining
Pools in the Constantia wine valley face long, hot summers followed by wet winters. Over the years that cycle takes a toll. Watch for these signs:
- The surface feels rough on feet and hands, or snags swimming costumes
- Dark stains that stay after brushing and shock treatment
- Fine cracks in the shell, often near steps or the waterline
- Algae that returns within days of cleaning
- The water level dropping faster than evaporation explains
If the pool is losing water, it is worth confirming the cause first. Our guide to finding hidden leaks in marbelite and gunite pools explains how we check before any lining goes on.
Our fibreglass pool relining process step by step
Every pool is prepared properly before any fibreglass is laid. Skipping preparation is what makes linings fail early. Our sequence looks like this:
- Drain the pool and let the shell dry
- Grind or sand the old marbelite or concrete to give the lining a sound key
- Repair cracks and any damaged areas
- Prime the surface
- Lay the reinforced fibreglass layer
- Finish with gelcoat, then refill
The work usually takes 5 to 10 working days, depending on pool size and weather. In Constantia, we plan around winter rain where we can, because the shell must be dry for the lining to bond well. You can read more about the method on our main fibreglass pool relining service page.
Fibreglass pool or marbelite resurfacing for your home?
Fibreglass is not the only option for a concrete pool. Marbelite resurfacing is the other route, and we do both. Some owners prefer the look of a fresh marbelite finish. Others want the smoother surface and lower upkeep of fibreglass.
After a site visit, our team will say which suits your pool. That depends on the condition of the shell, how the pool is used and what you want from it over the next decade or two. With proper care, a fibreglass lining lasts 15 to 25 years.
What Constantia pool relining costs
We do not quote a fixed figure on this page, because no two pools are the same. The cost depends on pool size, shape, condition and access. A pool behind a long garden with narrow side access takes more planning than one next to the driveway.

Fibreglass pool relining FAQs from Constantia owners
Can fibreglass pool relining go over old marbelite?
Yes. After draining, grinding, crack repair and priming, the lining can be applied over old marbelite or concrete.
How long is a Constantia pool out of use during pool relining?
Usually 5 to 10 working days, depending on pool size and the weather on site.
Will leaves still stain a fibreglass pool?
Leaves will still fall in, so regular skimming matters. The smooth gelcoat is far less porous than worn marbelite, which makes stains and algae easier to remove.
Is the fibreglass pool relining work guaranteed?
We guarantee fibreglass lining and repair work for up to 5 years, depending on the project.
Do you also do pool relining near Constantia?
Yes. We work across the Southern Suburbs, including pool repairs and relining in Tokai.
