Services
Pool Maintenance
Our regular pool maintenance ensures your pool remains clean, chemically balanced, and safe. We offer customised schedules including weekly, fortnightly, or monthly visits. Our fully equipped service vehicles allow us to handle all maintenance needs on-site, from water testing to equipment checks. With over 35 years of experience, we cater to residential and commercial clients across Cairns, including body corporate and real estate managers.
Vinyl Liner Repairs
Specialising in vinyl pool liner repairs and replacements since 1981, we fix cracks, splits, and bulges without draining your pool where possible. We use ABGAL and Aqualux liners in various colours and offer underwater repair techniques. Our process includes structural repairs, sand floor stabilisation, and vacuum-sealed installations for a wrinkle-free finish, ensuring long-lasting results for both above-ground and inground pools.
Acid Washing
Our acid washing service removes stubborn stains caused by chemicals, leaves, or metal fixtures. The three-step process involves draining, targeted treatment, and water chemistry rebalancing. We address calcium scale, rust, and tannin stains safely and effectively, restoring your pool's surface to like-new condition in just one to two days while minimising environmental impact.
Equipment Repairs
We repair all pool equipment including pumps, filters, chlorinators, and automatic cleaners. Our technicians service brands like Hayward, Zodiac, and Poolrite, offering on-site fixes or workshop repairs. We also replace outdated equipment with energy-efficient models, ensuring compatibility and optimal performance while maintaining QBCC-licensed standards for safety and compliance.
Energy Efficiency Upgrades
Reduce pool running costs by up to 75% with our energy efficiency upgrades. We install variable-speed pumps, LED lighting, and modern chlorinators that cut electricity use and maintenance needs. Our case studies show annual savings of $600$800 per pool, with break-even periods as short as two years. We also optimise filter systems and media for enhanced performance.

Marcus and Gretel have been looking after our pool for 8 years now. It 's wonderful to come home to see the pool sparkling when they have been. They provide an excellent , well priced and reliable service and when things go wrong ( like a pool full of leaves after cyclone Yasi) they are always available to come and sort it out quickly. We never even think about the pool, just enjoy it!

We have been clients of Marlin Swim Pool Service since late 2011 and are pleased to endorse the professional service provided by Marcus and Gretal. Marcus is an expert in the field of pool service and maintenance and readily provides advice on all things relating to pool service to ensure that our pool is kept in pristine condition. We have also found that Marlin Swim Pool Service only uses top quality chemicals and only provides what is needed. On a number of occasions we have had to call on Marcus to attend to problems such as our chlorinator and pool lighting and Marcus and Gretal provide prompt
