Your Friendly Licenced Local Plumber

McDiarmid Plumbing is a local and family owned and run business that has been successfully operating in South-East Queensland for over 34 years. With the current team there is over 125 years experience in the trade.

Mac and Judy McDiarmid founded operations in 1983, in Beechmont on the Gold Coast, with McDiarmid Plumbing being quick to get a reputation for reliable and trustworthy service. Mac’s passion for the trade and getting the job done right the first time, has attracted many up and coming apprentices and also experienced plumbers to be a part of the team which has led to many successful tradesmen now in the industry.

Continuing with the family business, Mac and Judy’s son Lewis has extended the brand to the Lockyer Valley and Toowoomba Region, offering the same amazing knowledgeable service. Being local to the area also allows him to maintain the values and quality of service that McDiarmid Plumbing customers have come to know and expect.

We service Gold Coast, Scenic Rim, Tweed and Northern NSW, Logan, Ipswich, Brisbane, Lockyer Valley and Toowoomba.

Mac McDiarmid

Mac started his plumbing apprenticeship on the Gold Coast in 1966, and soon after successfully completing his training, he and his wife Judy moved to Papua New Guinea for work and an adventure. The experience working in the area was invaluable as Mac was responsible for plumbing and drainage of existing native housing, roofing, water mains and brand new builds. After a number of years, Mac and Judy moved back to the Gold Coast to start a family and establish a business for themselves. Mac has built the McDiarmid Plumbing Service name from strength to strength, offering experienced and honest advice and workmanship since 1983 and is responsible for the plumbing and drainage of many Gold Coast iconic buildings and landmarks. Mac’s most passionate about finding solutions and getting the job done right, but also the training of up and coming plumbers and offering them a platform to be successful in the industry

Lewis McDiarmid

Lewis grew up in the McDiarmid household and was motivated to become skilled in a trade from Mac’s example. He started his apprenticeship in late 2008 and once completed he continued his employment within the family business. Due to the nature of work McDiarmid Plumbing is responsible for, he was given opportunities with a variety of experiences from highrises including fire services, to treatment plants, roof work, household renovations and many more, which built the foundation of Lewis’s knowledge. He moved to Toowoomba with his partner Kelly which allowed him to get a true feel for the area including the Lockyer Valley region. He also experienced a sense of the community working for a local plumbing firm, but has now been given the opportunity to extend the McDiarmid Plumbing name to the area, bringing with it the reputable success and experience our business is known for as well as Lewis’s contemporary skills and personable nature.
