We were recommended Mark and Mike by family and were not disappointed. We needed renovations doing including plastering, replacing piles, bathroom fit out, replacing rotten joinery and weatherboards. They started work promptly (within 4 days!) and were extremely good at communicating throughout the 3 week job. They liaised with all kinds of other trades and have done a FANTASTIC JOB. Very very pleased with their work ethic, tradesman ship and were excellent value for money.

Restricted building work in New Zealand must be carried out or supervised by a Licensed Building Practitioner. Confirm they hold a current LBP licence - and check their licence class and any disciplinary history - on the LBP public register before you hire.
Check the LBP registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
