Meet Mark Donnelly – Your Local Plumber

At MW Donnelly Plumbing, we believe plumbing is more than just pipes and fittings — it’s about solving problems, protecting homes, and earning trust. Founded and operated by Mark Donnelly, we’re a fully licensed, locally owned plumbing business based in Sunbury, Victoria, proudly servicing homeowners, small businesses, and real estate clients throughout the region.

With over 20 years of hands-on experience, Mark brings deep technical knowledge, a keen eye for detail, and a straightforward, honest approach to every job. You won’t find subcontractors or sales reps here — just a hardworking, qualified plumber who shows up when he says he will and gets the job done right the first time.

Locally Based, Community Focused

We live and work in the Sunbury region, so we know the area’s plumbing systems, water pressures, older homes, and council requirements. We’ve completed hundreds of jobs throughout:

Sunbury
Gisborne & Gisborne South
Bacchus Marsh
Craigieburn
Diggers Rest
Keilor Downs
Riddells Creek
Darley
Woodend
Taylors Lakes …and many other nearby suburbs.

We’re not part of a franchise or big business. When you call, you speak directly with Mark. When you book a job, he’s the one who shows up. That personal touch and local knowledge make all the difference.
