Blocked Drain FAQ's in Chester Hill
What causes blocked drains in Chester Hill properties?
Blocked drains in Chester Hill typically result from tree root intrusion in older clay pipes, grease and fat buildup in kitchen lines, or foreign objects flushed down toilets. Post-war and 1970s homes often have original terracotta or clay pipes where roots enter through microscopic cracks, expand over time, and trap debris. Kitchen waste solidifies as it cools, narrowing the pipe diameter and restricting flow.
How do you clear a drain blockage without damaging the pipes?
We use high-definition CCTV cameras to locate the blockage and confirm the pipe material and condition before clearing. High-pressure water jetting scours roots and grease from pipe walls without damaging PVC, clay, or cast iron lines. If inspection reveals structural damage or collapsed sections, we explain trenchless drain relining as an alternative to excavation and confirm scope before proceeding.
What should I do if a drain is backing up right now?
Stop using all fixtures connected to the affected drain to prevent further overflow. If water is actively backing up, isolate the fixture if safe to do so and avoid pouring chemical cleaners into a completely clogged drain. Call us for immediate dispatch; we operate 24/7 for emergency drainage situations and provide an ETA when you book.
How long does it take to clear a typical drain blockage?
Most straightforward blockages in accessible external or internal lines are cleared within one to two hours, including CCTV check and hydro-jetting. Complex blockages involving root intrusion or multiple restrictions may take longer, depending on the pipe condition and access. We confirm the scope and provide a time estimate once the blockage is assessed onsite.
Can tree roots damage my sewer line even if the tree is in the neighbour's yard?
Yes, tree roots seek moisture and nutrients, often travelling several metres underground to reach sewer lines. Roots from neighbouring properties can enter your pipes through cracks or joints, especially in older clay or terracotta lines. CCTV inspection identifies the root intrusion point and extent, allowing us to clear the line and recommend ongoing maintenance or relining to prevent recurrence.
What is the difference between hydro-jetting and using a drain snake?
Hydro-jetting uses high-pressure water to scour the entire pipe interior, removing grease, roots, and compacted debris. A drain snake (or electric eel) mechanically breaks up or retrieves blockages but may not fully clear residue from pipe walls. We select the clearing method based on the blockage type and pipe condition confirmed during CCTV check.
Do you provide a warranty on blocked drain unblocking work?
All drainage clearing work is backed by our Lifetime Labour Warranty on workmanship. If the blockage recurs due to incomplete clearing or workmanship issues, we return to assess and resolve it at no additional cost. The warranty covers the clearing work itself; it does not cover new blockages caused by ongoing root intrusion or pipe deterioration identified during the original inspection.
How much does it cost to clear a drain blockage in Chester Hill?
Pricing depends on the blockage location, access, pipe condition, and clearing method required. We assess the affected section onsite, confirm the scope using CCTV inspection where needed, and provide a fixed-price quote before starting work. The quote includes the clearing method, any follow-up verification, and site cleanup. To confirm the call-out fee status for Chester Hill, check when booking.
Can you clear blocked drains at night or on weekends?
Yes, we operate 24/7 for emergency drainage situations, including nights, weekends, and public holidays. Urgent jobs are dispatched immediately from our West Sydney hub. After-hours emergency work may attract a different rate structure; we confirm pricing before starting so there are no surprises when the job is finished.
What is drain relining and when is it recommended?
Pipe relining is a trenchless repair method where a resin-saturated liner is inserted into the damaged pipe, inflated, and cured to form a seamless internal surface. It's recommended when camera inspection reveals structural damage, root intrusion, or collapsed sections that hydro-jetting alone won't resolve. Relining restores pipe integrity without excavating driveways, landscaping, or internal floor slabs, reducing disruption and cost compared to traditional dig-and-replace methods.
