Customer Reviews


“AGH delivered exemplary service and results for my residential installation. I’d drawn a complete blank on how to move forward with the project from every other supplier I had spoken to – but Andrew and his team were a different league. Every challenge was overcome – on time and on budget.  I simply cannot recommend AGH more highly – my favourite contractors of all time.”  -  Richard Palmer Jones


“5-star work commenced in march 2021 fitting a wpl diamond treatment plant and associated works. From the first contact by telephone with Aimee work started within a couple of weeks and completed soon after. Great team highly recommended”  -  Michael Carroll   ☆☆☆☆☆


“We rate AGH very highly- from speedy response times, to high standards of work and communication, we do not hesitate to recommend them. Our long standing relationship will be continuing for years to come.”   Dee Sturman (Project/Property Manager) Brunning & Price


“We only installed an STP & pump station because of a change in the law and illegal discharge into a stream. Our lovely garden made this very difficult without causing serious disruption and damage, and with very tight access. AGH staff did a fine job, leaving the site with as little short term damage as possible. When problems were found they dealt with these with minimum fuss, and the necessary humour-- good job done , and all working well.“  -  Tim Kirk
