Blocked Drains on the Northern Beaches
Sand is the quiet culprit in most Northern Beaches drain blockages. Fine sand tracked in from Manly, Dee Why and Collaroy settles in traps, pits and shallow-fall stormwater lines, building up until the line silts closed. Low-lying Narrabeen and Warriewood have a high water table, so groundwater seeps into cracked sewer pipe and brings silt with it, and lines that surcharge in storms often flood subfloors before anyone notices. Up the peninsula, Avalon, Palm Beach and Frenchs Forest are steep and bush-fringed, with long stormwater runs that fill with leaf litter and bark every autumn. Holiday homes sitting unused for weeks add slow-forming blockages nobody catches early. We camera the line first, then clear it properly.

How we handle blocked drains on the Northern Beaches
1. CCTV inspection
We put a camera down the line before touching it. That shows exactly where the blockage sits, how far along it is and whether the pipe itself is cracked, offset or root-invaded, so you are not paying to guess.
2. High-pressure jetting
A jetter scours the full diameter of the pipe rather than punching a hole through the middle of the blockage. Grease, sludge, silt and debris come out with the flow, which is why a jetted drain stays clear far longer.
3. Mechanical root cutting
Where roots have found a cracked joint, we cut them back to the pipe wall with a root cutter, then re-camera to confirm the line is clear and to see the size of the entry point they came through.
4. Relining option
If the camera shows damaged pipe, we quote a no-dig reline: a resin liner cured inside the existing pipe that seals the cracks roots use. You see the footage first and decide, and nothing starts without written approval.
Every job is quoted on site and agreed in writing before work starts, so there are no surprises.

Recent blocked drains jobs in Northern Beaches
Sand-silted line, Dee Why
A beachfront unit block's stormwater backed up into a car park entry. Camera work showed sand filling half the pipe. We jetted the run to the street and cleaned every pit so the fall worked again.
Groundwater and roots, Narrabeen
A cracked sewer near the water table drew in silt and tea tree roots. We jetted and cut the line clear, then quoted relining the damaged section to keep groundwater and roots out for good.
Autumn leaf blockage, Avalon
A bush-fringe home flooded its lower deck each storm. We jetted bark and leaf litter from a long stormwater run, cleared the pits and fitted guards that can be lifted and rinsed by the owner.
