With over 70 years of experience, Mander & Co Ltd has the experts to provide professional advice and assistance with a variety of drainage work including:

  • Clearing blocked sewer and stormwater drains.
  • CCTV inspections.
  • Design and installation of soakage or dissipating systems.
  • Repairs to all drains, residential and commercial.


In the unfortunate event that pipes in your home burst and flood the nearby rooms, Mander & Co Ltd is able to offer several solutions:

If possible, in the first instance turn off the water at the mains and call 0800 MANDER/ 626 337 to arrange for a plumber to attend. Usually, the problem can be rectified and the water turned back on while together we plan the next steps.

There will be a number of repair options that are complex and need to be tailored to your specific situation. Due to the complexity of the fault, your plumber will provide expert advice once the situation is assessed. However, you should talk to your Insurance Company and reconsider any plumbing upgrade that you may have put off in the past which now may be able to be incorporated in any repairs.

Mander & Co Ltd is able to assist with any Building Consents, reinstatement of walls or ceilings and redecoration as required.


A “building warrant of fitness compliance schedule” often calls for a check of the “Backflow preventer.”

A Backflow preventer is a device that is designed to protect the potable supply from contamination by substances, chemicals or processes that are connected to or fed by the water we all drink. This may only be possible when the mains supply is turned off in the street or a pump is used in a process within the building.

We can assist in dealing with your local authority and can provide annual reminders about tests and preventative maintenance.
