Nick McKelvie

Owner of Alchemy Bathroom Renovations Auckland. Licensed Building Practitioner BP1021390 and registered producer statement author for waterproofing, PSA127420. Nick has renovated bathrooms in Auckland homes for 30 years and writes every guide on this site.

Every guide on this site is written by Nick McKelvie, the builder who runs each Alchemy job. Nick has spent 30 years in residential construction and bathroom renovation in Auckland, and the team has completed more than 1,200 bathrooms, from Ponsonby villas to townhouses in Botany. The advice in the guides comes from that work, not from a content brief.

Nick is a Licensed Building Practitioner, licence number BP1021390. Restricted building work, such as altering floor joists or wall framing in a bathroom, must be done or supervised by an LBP under the Building Act 2004. You can check the licence on the public LBP register.

He is also a registered producer statement author, PSA127420. Where a consented bathroom renovation needs a PS3 producer statement for the waterproofing, Nick issues it himself. That is why the waterproofing guide on this site reads the way it does. He has signed off the work it describes, and the Alchemy bathroom renovation team in Auckland backs that waterproofing with a 15-year guarantee.

Nick visits each job in person and quotes it in writing before anything is stripped out. He is the person you speak to on the phone and the person on site.
