What our customers say

Rated 5.0 out of 5 from 14 reviews on Google.

  • Our hot water system suddenly stopped working and we needed it sorted pretty quickly. Gave AC Plumbing & Drainage a call and he came out the same day. He explained what was going on in a really straightforward way and got the new system installed without any stress. Everything was left clean and it’s been working perfectly since.

FAQs

Frequently asked questions

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

  • 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.
