John Oldfield and the J.O. Plumbing team have been fixing plumbing problems across Knox for years. We know Ferntree Gully — the streets around Mountain Gate, the hillside homes near the Dandenongs, and the issues that come with them.
The hillside streets around Mountain Gate get hammered every storm. We install retaining-wall ag drains, upgrade undersized stormwater and reline root-cracked sewer mains for properties caught between the run-off above and clay soils below.
Local tip: If your Ferntree Gully retaining wall weeps water for days after rain, the ag line behind it is blocked or undersized — a quick CCTV will confirm which.
Flat $55 weekday call-out, $275 after-hours — no surcharge on parts or hourly rate at night or on weekends. Every job is quoted in writing before we start, and the price we quote is the price you pay.
Because we run a local team across Knox, when we're booked into Ferntree Gully we're often only a few minutes from a job in the next suburb over. That means faster response times and the same fixed-price quoting wherever you are.
