A swimming pool is one of the top must-haves for any Australian backyard. Everyone wants to buy something that represents value for money; no-one wants to make a purchase which they regret later. A critical decision when making a choice about a pool, is its lifespan. Will it ever need replacing and if so when and how can you tell that the time has come for a new one? Fibreglass pools are among the most durable around. Technology has improved so much that with the latest gelcoat technology, you can expect a swimming pool to last at least thirty years or longer.
