Our Services

Our Drainage Services in Onehunga

Drainage issues can escalate quickly if ignored. ASR Group Ltd helps Onehunga property owners identify and resolve problems before they cause serious damage to buildings and grounds.

CCTV Drain Inspection

CCTV drain inspections let us identify blockages, cracks, and root intrusion without any unnecessary digging. Older homes around Onehunga often have ageing clay or cast iron pipes that benefit from a camera inspection. We provide a full report so you know exactly what is happening underground.

Drain Cleaning

Blocked drains are a common issue in Onehunga, particularly in areas with mature trees and older infrastructure. Our high-pressure water jetting clears grease, debris, and root growth from your pipes quickly and thoroughly. Regular drain cleaning helps prevent costly problems further down the line.

Drain Maintenance

Proactive drain maintenance keeps your system running smoothly and helps catch minor issues before they become major ones. We schedule routine checks for residential and commercial properties across Onehunga. Staying on top of maintenance is the most cost-effective drainage strategy available.

Drain Repairs

Cracked, collapsed, or leaking drains can cause serious damage to Onehunga properties if left untreated. Our team carries out reliable repairs using quality materials suited to local soil and ground conditions. We restore your drainage system efficiently and keep disruption to your property to a minimum.

Vacuum Truck Loading

Our vacuum truck service is ideal for removing liquid waste, sludge, and debris from drainage systems and sumps across Onehunga. This service is especially useful for commercial sites and properties with high waste volumes. We handle disposal responsibly in line with Auckland Council requirements.

Root Cutting

Tree roots are a persistent drainage problem in Onehunga, where many streets are lined with mature trees that send roots into underground pipes. Our root cutting service removes intrusive roots and clears blockages without damaging your pipes. We can follow up with a CCTV inspection to confirm the line is fully clear.

Common Drainage Problems We Fix

Blocked or Slow-Draining Pipes

Slow drains are one of the most frequent complaints from Onehunga homeowners, often caused by a build-up of grease, soap, and debris over time. Mature trees throughout the suburb also contribute roots that gradually choke drain lines. Left untreated, a partial blockage becomes a full stoppage. High-pressure water jetting and root cutting can clear the line and restore normal flow.

Cracked or Collapsed Drain Lines

Older parts of Onehunga have ageing clay and concrete pipes that are prone to cracking or collapsing under ground movement and load. Warning signs include wet patches in the garden, sinkholes, or persistent foul odours near drains. A CCTV inspection confirms the extent of damage before any repair work begins. We carry out reliable repairs that restore full drainage function without unnecessary excavation.

Root Intrusion

Onehunga’s established street trees and garden plantings are a major source of root intrusion into residential drainage systems. Roots seek moisture and will find even the smallest crack in a pipe joint to enter and grow. Over time, they form dense blockages that are impossible to clear with a plunger. Our root cutting service removes the obstruction and a follow-up inspection ensures the pipe is clear and intact.

Stormwater Overload and Flooding

Heavy rain events can overwhelm stormwater systems in lower-lying parts of Onehunga, leading to pooling water around foundations and in yards. Poorly maintained or undersized drainage is often the underlying cause. Our team can assess your current stormwater setup, clear blockages, and recommend practical improvements to reduce flooding risk on your property.

We first contacted ASR in 2024 because we needed a second opinion after having difficulties getting another company to f/up on the compliance issues with Auckland Council. ASR responded quickly, and I was able to schedule appointments, unlike the other company, which would call me whenever they were in the area without an appointment. Recently, ASR helped me with the long-standing drainage issues around the house. As usual, James Rodney (Director) was good at responding as well as his teams (James (GM), Dedge and Kristine). The team arrived on time to carry out the work. They started at 8 am and didn't finish until 4.30 pm. One day, they even finished at around 5.30 pm so the work could be completed before the heavy rainfall in Auckland in April. The team also tidied up the place and ensured everything was in its place before they left. They were also very friendly and polite, and checked with me whether I was happy with their work before they left. Krissy would also call me after the work was completed to make sure everything was OKAY. Thank you, ASR Team :)

Frequently Asked Questions

Costs vary depending on the scope of work, but a basic drain repair in Onehunga typically starts from around $300 to $600. Larger jobs involving new drain installation or significant repair work can range from $1,500 to $5,000 or more. We provide a clear, itemised quote before any work begins so there are no surprises.

Simple repairs or drain cleaning jobs can often be completed within a few hours on the same day. More complex drainlaying projects, such as new installations or collapsed pipe repairs, may take one to three days depending on site conditions. Our team will give you a realistic timeline when we assess your job.

In Onehunga, any work that connects to the public wastewater or stormwater network typically requires a building consent and must be carried out by a licensed drainlayer. Auckland Council manages permit requirements in this area. ASR Group Ltd handles the necessary compliance documentation, so the process is straightforward for you.

Common warning signs include slow-draining sinks or showers, gurgling sounds from pipes, foul odours near drains, or wet patches appearing in your garden without an obvious cause. Onehunga properties with older pipes or large trees nearby are particularly prone to root intrusion and pipe deterioration. A CCTV inspection is the quickest way to get a definitive answer.
