Moved house and used a pool company closer. Big mistake totally got ripped off. Went back to sigma who are friendly, reliable, knowledgeable and above all trustworthy. Highly recommend the Sigma team at Balcatta. They're now an hours drive away, but worth the journey. Wouldn't go anywhere else. Thanks Clint.
- Richard Pyke, Wouldn't go anywhere else.
