Welcome to CH Drainage

Thank you for checking us out.  We are a small team of great people.  When you call you will usually be talking with Rob - our General Manager.  If you are calling related to a blocked sewer we almost always can get the job done that same day if you contact us in the morning.  Our blocked drain team deal with sewer issues, stormwater problems as well as complete video CCTV inspections of sewer and stormwater. 

We have two fully equipped drain laying teams - consisting of a drainlayer with an apprentice to deal with new work, repairs and maintenance jobs and earthquake repairs to damaged pipework.

We are still doing a lot of work related to quake damaged sewer and stormwater.  We can assist in the process from initial inspection, to preparation of the required documents for insurance or EQC, to completing the repair work.  Call us to discuss the options - you might just find the process is lot less painful than you think!

We look forward to being of help to you for emergency blockages, videos, new builds, renovations or earthquake repairs.

All the best.

Graham Boyd

Weekends and Public Holidays

We are closed on all public holidays and during the Christmas New Year period (usually 23 December until the end of the Stat days after New Year). If you have an urgent job call 03-3374018 and your call will be diverted to the on-call drainlayer.  Additional call out fees will apply on weekends and public holidays.


We are able to undertake a high definition CCTV video inspection of your Sewer and Stormwater lines. We will inspect your lines and provide you with a written report and DVD of the inspection and provide advice on what we have observed. Our recommendations are usually enough to prompt action from the council, insurers and EQC, when required.


Our teams will complete works inside the boundary of your property and, if needed, also on the council side.
