All pools have a life expectancy. Your pool's longevity can be lengthened by good care and maintenance. If, however, you have a pool that is not up to standard, Poolwise can assist in returning it to its previous glory.

Click on any of the items below to learn more about how Poolwise can assist you with any repairs you may require.

Repairs to Paving

Soil movement, poor initial paving or even aging building materials cause your pool to look unsightly. Sagging paving, especially behind the weir or returns, could be indicative of a leak.  Call us in for a quote to suit your pocket, in order to bring your property to its previous state of brilliance.

Sand Filters

On the coastal areas of KZN, it is imperative that the sand in your filter is changed every two years. Due to the tropical climate, the life expectancy of your filter sand is nowhere near as long as say the Highveld. The quantity of vegetation entering your pool and the sea climate, tends to break down the correct functioning of the sand.

Cracks and Leaks

Soil movement, poor initial construction or simply age cause cracks and leaks in your pool. Let our highly trained teams replace the surface of your pool to be as good as new, using modern products and techniques.


The surface of your Fibreglass pool can be affected by incorrect pH balance and chemical usage. We can refurbish this surface and get it back to its previous new state. Fibreglass surfaces are smoother and can make it very difficult for algae to grow on its sides. This type of pool surface uses less chemicals and is easier to maintain. It can, however, be a bit more slippery than other surfaces.

Gunnite / Marblelite

Our teams have been trained in repairing the surface of your pool by re-marbleliting it to look like new again. We are also able to line any pool with a gunnite or marblelite surface with Fibreglass.

Automatic Pool Cleaners

Outdoor pools are exposed to natural elements such as dust, leaves, grass and sand which lands in the pool and sinks to the bottom. Poolwise supplies all the latest models of pool cleaner and is proud to be a preferred partner of Zodiac, a supplier of the majority of the best models in the market place today. Automatic pool cleaners have a number of working parts and will last longer if they are properly looked after. The pH of your pool water is critical in determining how long your pool cleaner will last. Any level above or below normal ph will cause corrosion on the cleaner leading to eventual failure. Poolwise stocks all the necessary spares to fix any parts that might become worn or broken. Come in and we will assist you.


A salt chlorinator is an electronic device that takes salt and turns it into chlorine. Salt is made up of two elements - sodium and chlorine. When mildly salted water goes through the salt cell of a salt chlorinator, the chlorine is immediately dissolved to sanitise the water. The most effective sanitiser is chlorine. It will destroy bacteria, viruses, and algae in a swimming pool. A salt chlorinator simply separates the chloride molecule from salt to make the chlorine available. During this process, a small amount of ozone is produced, giving the swimming pool water an added sparkle as the sun reflects off the water. The chlorine molecule is then returned making salt again. The process is then repeated to maintain clear sanitised water to enjoy.

  • The two elements of a chlorinator are basically:
  • 1. The Power Supply and PC board (controlling the salt cell and flow of water for continual testing)
  • 2. The salt cell sealed and electrical plates used to separate the chlorine molecule from the salt solution.

Life expectancy of the average chlorinator is three years. We have a state of the art testing facility in our workshop. The main problem with PC boards is rust from our harsh climate at the coast. If the board cannot be repaired by our engineer we can replace the board for you. We are also able to replace faulty cells. We will assist as much as much as possible and will collect your chlorinator for repair on request.


Electrical work for a pool is critical for both your safety and the ease of maintenance. The challenges faced, however, are varied depending on each site and installation.

  • The following should be taken into account:
  • Where is your pool in relation to your electrical supply?
  • Is your electrical supply compliant with the latest standards and sufficient power for the pool?
  • Will your pump be housed in a water tight device?
  • Do you have the correct earth leakage devices?
  • Will there be a chlorinator installed?
  • Is there a pool heater?
  • How many and what type of lights are installed and in which locations?
  • All our installations are carried out by a qualified electrician who will provide the necessary certificates supplied when required.
  • We are frequently asked to determine why the pool is tripping the lights and the quality of the installation will determine how easy this is to identify and resolve.


Most pools today use sand filters but we are able to support all other types in the market. Filter sizes vary depending on pool size. The water is filtered through weir and pump baskets to catch larger debris like leaves and grass, but the finer particles are trapped by the sand in the filter. Sand will trap all the small particles suspended in the water, filtering the water. Regular backwashing of your filter according to manufacturer specifications will prolong the life of your sand. Body lotions, hair and pet hair coat and block the filter sand, which needs regular changing.

Pool Plumbing

The plumbing for a pool is simple in concept as it merely gets the water from the pool through the filter and back to the pool again. The challenges faced, however, are varied depending on each site and installation.

  • The following should be taken into account:
  • Ground conditions
  • Location of weirs and inlets
  • Infinity edges / rim flow
  • Sizes and positions of sumps for rim flow pools
  • Location of the pump and distance from the pool itself
  • The route the pipes must take to get to and from the pump
  • Introduction of salt chlorinators
  • Introduction of pool heaters or solar collectors
  • Weather conditions
  • Housing conditions
  • Incorrect or poor installations
  • Use of inferior equipment or low pressure piping
  • Other work in and around the pipes
  • All of the above challenges will determine how your plumbing is done and how well it can be maintained.

The most frequent challenge with an existing pool is the occurrence of a leak. We at Poolwise have a wealth of experience in this regard and are able to determine where a leak is and how to repair it.

Pool Pumps

There are a variety of pumps in the market place today. Some are obviously better than others which may also have superior manufacture warranties than others. It is essential to install the best pump that you can afford for long-term benefit. For this reason, we only sell top quality pumps as bad pressure from a poor or incorrectly specified pump results in poor water circulation. Circulation is necessary for getting all your water treated each day and your pump should be running at least 8 hours per day. This is approximately 240 hours per month.

Retainer Walls

All walls or retainer walls over one metre in height have to have an engineer’s certificate as they can be a hazard. We, at Poolwise, can repair or install walls in order to improve the area around your pool. The surrounding area of your pool makes such a difference to the overall appearance. Let us know what we can do to improve your property.
