Alexandra Hills is the most consistent suburb in Redland City. It is mass 1970s and 1980s subdivision on compact lots, laid out and built in a short window, which means a street here tends to have the same vintage of sewer line, the same vintage of stormwater run and the same age of planting the whole way down. Redlands Blocked Drains is a local referral service. We put you in touch with QBCC-licensed local drain plumbers who service Alexandra Hills.
Why Alexandra Hills drains block
That consistency is the whole story, and it cuts both ways.
The useful side is that a plumber who has cameraed one line in your street has a very good idea what is in the ground under the next one. The unwelcome side is that if your neighbour has just had a root blockage cleared out of an open clay joint, you are probably a season or two behind rather than lucky.
Lines of that era are jointed, laid in short sections, and have now had forty to fifty years of ground movement working on them. The trees planted when the estates went in are fully mature, and their feeder roots have found the joints. The compact lot sizes put established trees close to the house and close to the line, which shortens the distance roots have to travel.
The second pattern is ordinary household load on ageing pipe. Wipes, fat and sanitary items block a narrowed, root-lined pipe far more readily than they block a clean one, so the thing that finally stopped the drain is often not the thing that caused the problem.
The council's three-step test
Redland City Council publishes a short diagnostic, and it costs nothing to run.
- One fixture slow and the rest of the house fine means the problem is most likely in your home's plumbing.
- The overflow relief gully overflowing while no water is being used on the property means the blockage is likely to be in the council's sewer main. Clear any obstruction, check the grate moves freely, then contact the council.
- An inspection opening that holds water or drains slowly while an indoor tap runs means contact the council. Dry means the house plumbing, so call a plumber.
The sewer mains in the sewered parts of the Redlands belong to Redland City Council, through its water and wastewater business, City Water (previously Redland Water). Your own drain line, from the house to the connection point, is yours, and the council states that the inspection opening is the owner's to install and maintain. If the blockage turns out to be the council's, a plumber has to confirm it and it has to be reported immediately for a reference number. The full guide walks through it.
What clearing a blocked drain involves
The licensed drain plumbers we work with usually start with a CCTV drain camera, then clear the line with jet blasting, which cuts the root mass out and cleans the pipe wall rather than punching a hole through it. For a line that has blocked more than once, relining seals the joints from inside and leaves nothing for roots to enter, usually without digging up the yard. It also keeps the tree, which matters here, because the council's vegetation local law and the state's koala mapping make tree work a permit question in the Redlands.
A standard clear typically costs $150 to $400. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. Relining typically runs $3,000 to $8,000 or more depending on length. You get a price before any work starts.
Frequently asked questions
Everyone in my street seems to get blocked drains. Is that normal here?
It is common, and there is a reason. The estates went in at once, so the pipe age, the pipe material and the tree age are the same along the street. Shared causes produce shared symptoms.
Should I reline before it blocks again?
If a camera has shown root intrusion at multiple joints and you have paid for more than one clear, relining usually works out cheaper over a few years. If the camera shows a sound pipe and the blockage was wipes, it does not.
Can I just have the tree cut down instead?
Not through this site, and probably not easily at all. Most of the Redlands mainland sits inside the state's koala mapping, and the council has its own vegetation protections. Clearing the roots and relining the pipe is the practical answer, and it leaves the tree alone.
Does the age of my house tell me what pipe I have?
It is a good first guess. A late 1970s or 1980s Alexandra Hills house commonly has jointed line of that era. A camera confirms it in minutes, and the material is the best predictor of whether this will happen again.
