"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."

Slow drain? Sewer back-up? Tree roots? We use camera inspection, hydro-jetting and traditional rodding to clear and resolve any blockage — and document the cause for next time.

Most blocked drains are a symptom of something bigger — tree root intrusion, broken pipework, fat or grease buildup, or foreign objects. We don't just clear the immediate blockage; we find the cause and explain your options.
Our drain camera inspections produce a recorded video walkthrough of your underground pipework, with reference markers and a written report.
Hydro-jetting: high-pressure water (up to 5,000 psi) cuts through grease, scale and small roots. Best for ongoing maintenance and grease blockages.
Mechanical rodding: spring-steel coils with various heads — best for solid blockages and root masses.
Camera inspection + relining: where a pipe is broken, we can install a cured-in-place liner without digging up your garden.
Yes — hydro-jetting cuts through small to medium roots, mechanical rodding handles large root masses, and pipe relining (no-dig repair) is available for roots that have cracked the pipe. We provide a recorded camera inspection and council-grade certification.
Almost never. We use pipe relining (cured-in-place lining) to repair broken sewer pipes without digging up your garden. Only in extreme cases (pipe collapse, replacement) is excavation needed — and we restore landscaping as part of the job.
Standard residential blockage: typically $250–$650 depending on access and severity. Severe root masses or pipe damage: more — we always provide a fixed quote after the camera inspection before doing the major work.

"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."
"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
