Drain Repairs: Choosing the Right Repair

Understand what needs attention

Bring earlier inspection findings and the history of blockages together. A symptom may justify investigation, but it does not select the repair method by itself.

The collapsed drain signs guide explains what to record and why pipe condition needs checking.

Plan the investigation

We use CCTV and pipeline robotic cameras with GPS location to investigate drainage concerns. Agree the question the inspection needs to answer and the sections involved.

Our CCTV drain inspection cost guide helps compare access, preparation, locating and how findings will be explained.

Compare repair methods

Relining, local repairs and replacement involve different preparation and access. The best discussion starts with the affected section, connections and surrounding surfaces.

Use pipe relining versus replacement to compare the practical choices. Then review pipe relining cost factors if lining is being considered.

Define the local repair scope

Tell us which part of the property needs to remain usable and what sits over the drain. Include concrete, hot mix, pavers and gardens in the reinstatement discussion.

Our Christchurch drain repair service outlines the enquiry information for an existing fault.

Plan installation and connection work

A new drain or replacement project needs a clear brief covering purpose, route, access and responsibilities. Share available plans and the sequence of other building work.

See drainlayers in Christchurch for project scoping. For an on-site system, the septic installation budget checklist includes items beyond the tank.

Check the connection and responsibility

Find out which network and ownership arrangement applies before assuming who handles a fault. Keep council advice and drainage plans with the investigation findings.

Our sewer lateral explainer introduces the property's wastewater connection and the questions to ask.

Start here

1. Define the inspection you need.
2. Compare the repair methods.
3. Discuss repair and reinstatement.

Ask each proposal to identify the repair extent, preparation, completion checks and any exclusions. We can discuss those details against the conditions found at your property.
