Signs you have a drainage problem in Aranui

Drainage faults rarely announce themselves. These are the ones worth calling about before they turn into a dig.

  • Spouting sagging or overflowing Leaking at the joins, or spilling over in heavy rain.
  • Water running down the house Instead of into a downpipe, or pooling at the foundations.
  • Slow or backing-up gully trap Especially after a downpour.
  • A blockage that keeps coming back Clears, then returns a few months later.

Any of these are worth a look. Call us on 03 379 0711 and we will CCTV the line before quoting anything.

Local

What the ground is like in Aranui

Aranui is one of the more straightforward suburbs in Christchurch to work in, which keeps the cost of most drainage jobs down.

The ground in Aranui is flat and easy to dig, much like neighbouring Woolston. That is the single biggest factor in what a drainage job costs. The same work on a Mount Pleasant or Redcliffs hillside takes longer, needs more care with backfill, and usually means getting through rock first.

Where the stormwater actually starts

Drainage is not only what is underground. In Aranui’s older homes, spouting and downpipes take a lot of UV and wear out faster than people expect. When they go, water that should be heading into the stormwater system ends up running down the side of the house or pooling against the foundations instead.

It is worth looking up as well as down. If your spouting is sagging, leaking at the joins or overflowing in heavy rain, the drain underneath it is not the problem. We check both while we are on site rather than fixing one and leaving the other.

Minor alterations

Most of what we do here is minor drain alterations. Moving a gully trap, reconnecting a run, altering drainage for an extension or a new outbuilding. On flat, easy ground these are generally quick jobs, which is worth knowing if you have been putting one off expecting it to be a big spend.

Underground

What is probably under your Aranui property

Drainage is the one part of a house nobody ever sees. Here is what we usually find under Aranui properties, and what it means.

  • Older home
    Clay, laid in short lengths A lot of joins, and roots find every one of them.
  • Replaced runs
    PVC on the replaced sections New pipe meeting old pipe, so faults tend to show at the joins.
  • Ageing spouting
    Stormwater not reaching the drain properly Looks like a drainage fault, but the problem is above ground.
  • Flat section
    Accessible runs and straightforward connections Alterations are generally quick and cheaper than on a hill section.

Our process

How we find the problem before we dig

Digging blind is expensive. We work out exactly what is wrong and where it sits, then quote the fix.

Check above ground first

In Aranui a surprising number of drainage complaints start with worn spouting or downpipes. We look there before assuming the problem is buried.

CCTV the line

If it is underground, we run a camera through the drain and see exactly what is happening and where it sits. No guesswork and no exploratory digging.

Quote the real fix

Once we know what is going on we quote it properly. On flat ground most Aranui alterations come in quicker and cheaper than people expect.

Frequently Asked Questions

Aranui drainage questions

Can I get help paying for drainage work in Aranui?

It is worth asking your bank. Some lenders offer home loan top-ups or green home lending that can cover this kind of work, and most people do not think to ask. We cannot advise on lending, but we are happy to provide a written quote you can take to them.

My spouting overflows in heavy rain. Is that a drainage problem?

Often it is the cause rather than the symptom. Aranui's older homes get a lot of UV on the spouting and downpipes, and once those start leaking or sagging, water that should be going into the stormwater system ends up against the house instead.

How much does a minor drain alteration cost in Aranui?

Less than most people expect. Aranui's flat, easy-digging ground means the same alteration costs noticeably less here than it would on a Mount Pleasant or Redcliffs hillside. We quote after looking at the job rather than over the phone.

My drain keeps blocking. Does the whole line need replacing?

Not necessarily. Recurring blockages usually mean roots at the joins rather than a failed pipe. A CCTV inspection shows whether the line is structurally sound and can be cleared, or whether a section needs replacing in PVC.

Do you charge extra for drainage call-outs in Aranui?

No. Drainage work in Aranui is charged at our standard rates, the same as anywhere else in Christchurch. We only add travel for jobs outside the metro area like Kaikoura or Akaroa.

Do you handle urgent blocked drains in Aranui?

We respond to priority repairs during business hours. Call us and we will dispatch the nearest qualified drainlayer and give you an estimated arrival time. If we cannot get there soon enough, we would rather recommend another trusted tradesperson than leave you waiting.
