“Myself and my team choose Brendan & Andy and their team from G&L Plumbing and gas for many of reasons. Being a Civil Earthworks company we need experienced plumbers to assist with our projects and G & L plumbing and gas never disappoint. We have been blown away over the years in all aspects of service from the team and has simply made our lives that much simpler by having such contractor we can trust. My wife runs hotel venues in the Perth south area and has had G & L Plumbing and gas as there no 1 plumbing contractor for the last few years and team always reacts accordingly to breakdowns and maintenance issues. Cannot recommend G & L Plumbing and gas enough!"
