Out-of-hours overcharging and 'while I'm here' add-ons are common complaints. - Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work. - Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start. - In New Zealand, restricted building work must be carried out or supervised by a Licensed Building Practitioner, and all electrical, plumbing, gasfitting and drainlaying by a licensed tradesperson (EWRB for electricians, PGDB for plumbers and gasfitters). Check the public register before you hire. - For residential building work of $30,000 or more you are legally entitled to a written contract and a disclosure statement setting out the tradesperson's skills, licences and insurance. Ask for both before work starts. ## Contact - Phone: 0800 464 652 - Website: http://www.drainninjas.co.nz/ --- Source: MyTrustedTraders, https://nz.mytrustedtraders.com/traders/mtt264206-drain-ninjas-henderson-plumber Real public evidence only: every figure traces to its named source.
