Plumber in Thornbury

Licensed plumbing, drainage and gas fitting across Thornbury, on streets of Californian bungalows where the roof and the drains are both original.

Plumbing and gas fitting in Thornbury

Thornbury sits directly between our Preston base and Northcote, so it is a few minutes away and same-day attendance is usually available. Our phone is answered 24 hours a day, seven days a week.

Thornbury has a heavier concentration of inter-war Californian bungalows than almost anywhere else in the inner north, and that housing type brings its own list. The hipped and gabled terracotta roofs are full of valleys, and a valley that has rusted or filled with leaf litter pushes water back under the tiles instead of into the gutter. The verandahs are wide, which means long runs of gutter and downpipe that were sized ninety years ago. Underneath all of it the drainage is usually original too. So the pattern here is a leak that looks like a roof problem and turns out to be a blocked downpipe, or a drain that backs up every time the roof sheds a storm into it at once. We follow the whole path the water takes rather than just the end of it.

  • We received amazing service from AC Plumbing & Drainage. They sorted out our blocked drain quickly and explained everything clearly. Friendly, reliable and reasonably priced. Would definitely use them again!

  • We had heaps of issues with blocked drainage at our old property in the Darebin area. We didn’t really know what was going on, nor did the guys before AC. Driveway flooding became a bit of an issue. When we called AC he arrived the same afternoon and sorted it quick fast! He’s got all the right gear and set up. Actually, I’m writing this 3 months since his visit and no dramas! I’ve referred him to a couple of friends and they’ve both got good feedback... Would definitely use them again!

FAQs

Frequently asked questions

Answers to the questions we are asked most often. If your question is not covered here, call us.

  • Water is coming in near the ceiling but the roof looks fine. What is it?

    On a bungalow it is usually not the tiles. The common causes are a rusted valley where two roof planes meet, a gutter or downpipe blocked with leaf litter so water banks up over the edge of the tiles, or a box gutter that has lost its fall. All three let water in a long way from where the stain appears inside, which is why patching the ceiling end never works. We find where it is getting in first.

  • My bungalow still has its original terracotta roof. Do you work on those?

    Yes. Allan is registered for roofing and stormwater under licence 47581, which you can check on the Victorian public register. On an original terracotta roof most of the work is the plumbing around the tiles rather than the tiles themselves: valleys, flashings, gutters, downpipes and where they meet the stormwater line.

  • Do you cover all of Thornbury?

    Yes, all of 3071. That is both sides of High Street and the St Georges Road tram corridor, from the Northcote border in the south up to Preston in the north. Preston is where we are based, so Thornbury is one of the shortest trips we make.

  • How quickly can you get here?

    Our phone is answered 24 hours a day, seven days a week. We are based in Preston and work across the northern suburbs, so response times are short. For emergencies we will give you a realistic arrival time on the phone, and advise you on isolating the water or gas in the meantime.

  • What does a call-out cost?

    You receive a free quote before any work begins. We assess the job, explain what is involved and confirm the price with you. No work goes ahead until you have approved it.

  • Do you work after hours and on weekends?

    Yes. We are available 24 hours a day, seven days a week for emergency plumbing and gas work.

  • Which suburbs do you cover?

    Preston, Reservoir, Thornbury, Northcote, Fairfield, Ivanhoe, Heidelberg, Heidelberg West, Macleod, Greensborough, Bundoora, Mill Park, Epping, Lalor, Thomastown, Coburg, Brunswick, Fawkner, Glenroy and Pascoe Vale, along with the surrounding northern suburbs. If you are just outside this area, call us and ask.

  • Can you find a drain fault without digging?

    In most cases, yes. We run a CCTV camera through the line and record the condition of the pipe, which identifies the fault and its depth from the surface. Any excavation is then limited to that one location.

  • Do you do gas fitting as well as plumbing?

    Yes. We install and connect gas appliances, run new gas points, detect and repair leaks, and carry out carbon monoxide safety checks. Every gas installation is tested and certified on completion.
