Davidson is a small, leafy suburb of mostly 1970s homes tucked between Garigal National Park, Belrose and Frenchs Forest. Big gardens, bush on the doorstep and drains that are now around fifty years old make a familiar combination. Beaches Blocked Drains is a referral service. We connect you with licensed local drain plumbers who service Davidson.
Why Davidson drains block
The original sewer lines in many Davidson homes are earthenware or early pipe from the 1970s building era. Joints that were tight when laid have opened with decades of ground movement, especially where the soil is clay-rich. Roots from the national park edge and from garden trees find those gaps.
Sloping streets toward the bushland send stormwater downhill fast, and pits at the bottom of the block fill with soil, bark and leaves. Where the stormwater line is partly blocked, heavy rain ends up against the house or under the subfloor.
How the plumbers we refer approach it
A CCTV drain camera first, to find out whether roots are just in the pipe or have cracked it. Then jet blasting to clear the line. If the pipe is damaged, pipe relining seals it and stops the cycle of repeat clears.
What it costs in Davidson
A standard clear typically runs $150 to $400. Root clearing typically runs $250 to $600. A camera and jetting combination typically runs $350 to $900. Relining typically starts around $3,000. You get the price before work starts.
Frequently asked questions
Our 1970s home has never had a drain problem. Should we worry?
Not necessarily, but pipes from that era are reaching the age where roots and joint movement show up. If you notice gurgling or slow drains, get it checked early.
Water gets under our house in heavy rain. Is that drainage?
Often. A blocked stormwater line or pit, or a downpipe that discharges too close to the house, can send water into the subfloor. A plumber can trace the cause.
Can we avoid digging up the garden?
In most cases. Clearing and relining work through existing access points, and a camera inspection keeps any digging small and precise.
