High-pressure water jetting removes built-up debris, grease, scale, and tree roots from drain lines. It’s a fast, powerful method that restores full pipe capacity and reduces the risk of recurring blockages.
-
We diagnose and clear blocked sinks, toilets, stormwater lines, and sewer drains using hydro jetting, mechanical root cutting, plunging systems, and CCTV diagnostics. Ideal for urgent call-outs or recurring issues.
-
Our camera inspections locate cracks, misalignments, collapsed pipes, foreign objects, and stubborn blockages with pinpoint accuracy. Clear reporting helps you understand the condition of your system before committing to repairs.
-
Full septic cleaning and pump-outs using vacuum trucks, with filter checks, baffle assessment, and system health reporting. Suitable for lifestyle blocks, farms, and properties not connected to mains wastewater.

CCTV Drain Inspection
When you need more than a quick unblock, our CCTV drain inspection gives you a detailed, non-invasive look into your pipes. We insert a high-definition waterproof camera that transmits live footage to identify issues such as cracks, misalignment, blockages, or root intrusion, without digging.
Typical Uses:
Pre-purchase house inspections
Recurring blockages that don’t respond to conventional unclogging
Preventative maintenance for commercial drains
Planning for pipe repairs or relining
What You Get:
A full video report, clear recommendations, and a roadmap for remediation, saving you time, effort, and guesswork.
Drain Unblocking
Our drain unblocking service fixes everything from slow drains to full sewer backups. We use a multi-tool approach: CCTV inspection to diagnose the problem, mechanical snaking for tough blockages, and hydro jetting where needed.
Common Causes We Handle:
Hair & soap residue
Food waste and grease
Tree roots
Structural damage or cracked pipes
Why Choose Us:
We don’t just clear the blockage — we find the root cause and give practical advice to avoid future issues.
Hydro Jetting
Hydro jetting is our go-to solution for clearing persistent blockages that other methods can't touch. Using high-pressure water (up to ~4,000 PSI), we blast through built-up grease, tree roots, scale, and debris — restoring full pipe flow and capacity. It’s fast, effective, and environmentally friendly, making it ideal for both residential and commercial systems.
When to Use It:
Heavy grease buildup in kitchen or restaurant drains
Recurring clogs that come back soon after being cleared
Root intrusion in older or landscaped drain lines
Full sewer-line cleaning or preventative maintenance
How It Works:
A specialist hose with a high-powered nozzle is inserted into the drain, and pressurised water is applied to scrub and flush the interior surfaces of the pipe. This deep clean helps prevent future buildups and reduces the need for frequent maintenance.
Septic Tank Cleaning & Servicing
We provide professional septic tank cleaning and maintenance across rural and suburban Auckland properties. Using vacuum trucks and skilled staff, we safely remove sludge and liquid, inspect system integrity, and clean filters, all in compliance with environmental regulations.
