Irene has large, heavily treed stands and a good deal of borehole use. Both leave marks on a pool that get misread as faults with the pool itself.
Below is what actually tends to be going on, and what to raise before accepting a quote here.
The Ground: Old Trees, Borehole Water, Dolomite Below
The village and the surrounding stands carry mature trees on generous erven, and many properties draw at least some water from a borehole. Underneath, the dolomitic geology of the Centurion area still applies, so leaks remain a priority.
- Borehole water is hard and often metal-bearing. Iron and manganese in groundwater stain surfaces brown or grey-black, and hardness scales the waterline, the heater and the salt cell.
- Heavy leaf and organic load. Mature trees drive chlorine demand up, block skimmers and tannin-stain older finishes.
- Root systems over old services. On large established stands the pipework has had decades of competition.

Get Irene Pool QuotesWhat Goes Wrong With Pools in Irene
- Brown or grey staining that returns after every top-up, which is metals in the fill water rather than a dirty pool.
- Scale at the waterline and in the heater, from hard borehole water.
- High chlorine demand under continuous leaf fall.
- Slow pressure-side losses on long buried runs across large stands.
The pool stock here
A mix of older village properties with established pools and larger newer homes on the surrounding stands. Long pipe runs are common because plant is often well away from the pool.
Staining that comes back every time you top up
This is the signature of metals in the fill water. Iron oxidises to brown, manganese to a grey-black, and both plate onto the surface as soon as they meet chlorine. Treating the stain without treating the source guarantees it returns.
The fix is sequencing: treat the water, then the stain, then manage top-ups. See pool cleaning for stain work and pool equipment repairs for filtration options.
Scale from hard water
Hard borehole water deposits calcium at the waterline, inside heaters and on salt chlorinator cells. A cell furred with scale reads as a failed cell and is often just dirty, and a heater full of scale loses efficiency long before it fails.
Descaling and balancing beat replacing. See pool heater repairs and pool equipment repairs.
Long pipe runs on big stands
Where the plant room is thirty metres from the pool, there is a lot of buried pipe, and a lot of places for a slow loss to hide. It also means suction lift and friction losses that a badly matched pump struggles with.
Testing the lines separately is the way in. See pool leak detection and pool plumbing repairs.
Access and Property Type in Irene
Access is generally good on these stands, but distance is the constraint rather than width. Long driveways and pools set well back from the road mean material handling over distance, and some properties have heritage or estate constraints on what can be altered.
When comparing quotes, check each has assumed the same access. A quote priced on driving to the pool and one priced on barrowing are not comparable, and the difference is not one contractor being cheaper.
Pool Repair Prices in Irene
Metro ranges apply. In Irene it is water chemistry and long service runs that most often add to a job, rather than the repair itself.
| Job | Indicative range | Irene notes |
|---|---|---|
| Leak detection survey | R1,500 – R5,000 | Test the fill water before treating stains, or you will treat them repeatedly. |
| Pump repair | R800 – R4,000 | Hard water shortens salt cell and heater life. Descaling is cheaper than replacing. |
| New pump, supplied and fitted | R3,500 – R18,000 | Long pipe runs mean more buried line to test and, if needed, replace. |
| Filter repairs / sand change | R1,100 – R5,000 | |
| Structural crack repair | R3,000 – R20,000+ | |
| Re-Marbelite | R450 – R700 /m² | |
| Fibreglass lining | R600 – R850 /m² | |
| Full renovation | R20,000 – R150,000+ | |
| Coping replacement | R450 – R1,200 /m | |
| Paving lift and relay | R250 – R550 /m² | |
| Monthly maintenance | R700 – R1,800 /month |
These are indicative market ranges, not a quotation. They are compiled from published South African pool industry pricing to give you a starting point for budgeting. They are not the rate card of any company on this platform, and no figure here is a commitment by anyone.
Published pool pricing in South Africa varies widely — different 2026 guides quote ranges for the same job that differ by a factor of three — because pool size, surface area, access, the condition of what is already there, and how much preparation is needed all move the number. Figures generally exclude VAT unless noted, and change over time. Only an itemised written quote against your actual pool means anything.

Irene Pool Repair FAQs
My pool stains brown a few days after every top-up. Why?
Almost certainly iron in your borehole water. Dissolved iron is colourless in the ground, but as soon as it meets chlorinated water it oxidises and plates onto the pool surface, which shows as brown staining that brushing does not shift.
Treating the stain without addressing the fill water means repeating the treatment after every top-up. A sequestering agent at fill, or pre-filtration on the borehole line, is what breaks the cycle.
Is borehole water bad for a swimming pool?
Not inherently, but it usually needs managing. Groundwater here tends to be harder than municipal supply and often carries iron or manganese, which cause scaling and staining respectively. Both are manageable once you know what is in the water.
A water test is the starting point and it is inexpensive. Filling a pool from an untested borehole and dealing with the consequences afterwards is the expensive order to do it in.
My salt chlorinator says the cell has failed. Does it need replacing?
Check whether it is scaled first. Hard water furs the plates with calcium, which reduces output and often triggers a cell warning on a cell that is otherwise sound. A proper descale restores it in many cases.
If output stays low after descaling and the plates are visibly worn, then it is genuinely at the end of its life. Cells are consumables, but they should not be consumed in two seasons.
Do you repair pools in Irene yourselves?
No. This is a free service that connects Irene pool owners with swimming pool repair companies working in the area. You describe the problem once, companies covering your area receive it, and they quote you directly.
The inspection, the quote and the repair are carried out by the company you appoint. Your agreement is with them.
How much do pool repairs cost in Irene?
The variables are the same as anywhere: what has actually failed, whether anything must be excavated, whether the pool has to be drained, and the pool's surface area. Indicative market ranges are in the table above and on each service page.
No fixed price is published because pool repair scopes vary too much for a rate card to be honest. An itemised written quote after an inspection is what lets you compare properly.
