“From the moment we first  contacted Mainmark, they have been an absolute pleasure to work with. A highly skilled, professional, friendly and knowledgeable team from marketing and sales right through to the personnel on site reassuring us at every step of the way, going the extra mile from the outset together with negotiating and coordinating with the Insurance Company. I also can’t praise the men on site enough for their meticulous attention to detail and attitude in appalling weather conditions. Moving a 5 ton + chimney 170 cms without any cracking in a few hours. A miracle!
Thank you J—- and all at Mainmark.”

Andy, Warkworth, NZ. June 2019

“I am writing to say that we are delighted at the result achieved on the job at our property today. We were hugely impressed with your team of D—–, N— and G—: their professionalism, commitment to the task, smooth interworking, and the way they interacted with us could not have been faulted. I think you are very lucky to have such committed staff. You yourself were also a model with whom to deal. Straightforward, fast in response, open about difficulties, never impatient with dumb questions. Feel free to use me as an example of a very satisfied client.”

Brian, Red Hill, ACT. May 2019

“I’m pleased to recommend Mainmark, who recently did some groundwork engineering for me. They were technically capable in a field where there are not many operatives in this country and, in addition, they were considerate and thorough. The Company went beyond their original brief to deliver the best possible service. Thank you.”

Alan, Puhoi Orewa, North Island, NZ. March 2019

Marisa, Footscray, VIC. March 2019

“This is just a short note to thank you and all others associated with Mainmark’s work at this address. All aspects of the work were handled most professionally and politely and, so far at least (only a week has elapsed), the work has been utterly successful. Doors that were difficult now shut easily (with one exception, which can be quite easily fixed) and cracks that were noticeable have almost disappeared.
My wife and I thank you for the work, and you and all the team members for the way it was handled.”

Anthony, Ringwood, VIC. February 2019
