A blocked-drain plumber can investigate slow or backed-up sinks, toilets, sewer or stormwater lines and recommend the right clearing method. Say which fixtures are affected, when it started and whether wastewater is overflowing. The local blocked-drain listings below are a starting point; confirm the business handles your drain type and ask about callout, inspection, clearing and follow-up repair costs.
Sewage overflowing indoors? Keep people clear of contaminated water and contact a plumber promptly. Report a public sewer fault to the responsible utility.
Note which fixtures are slow, whether more than one is affected, recent rain and any previous clearing. Do not assume a street or utility-owned sewer is your private plumbing; ask the utility or council if the problem is beyond the property connection.
Avoid adding chemicals before a plumber inspects the system, and keep clear of overflowed wastewater.
Compare investigation and clearing
Ask for callout, camera inspection if needed, clearing method, disposal, after-hours charges, any separate pipe repair, evidence of the cause and GST. A cleared drain may still need a repair if the underlying pipe is damaged.
Good questions. Plain answers.
Can I request a quote before knowing the blockage location?
Yes. Describe the symptoms and ask what the inspection and clearing charges cover.
Who fixes a blocked street sewer?
The responsible water utility or council may need to investigate; check your local service boundary.
