We're happy to have helped

“Great to see you on Tuesday and thank you and S____ and the team for the great job on our foundations. We are really happy with everything.”

Jacinta, Spotswood, VIC. February 2020

“The guys turned up early today (after a warning call that I missed) and got stuck in. Couldn’t hope for a more personable and competent team. They did you proud.

We are very happy with the result. All the cracks closed up either a little or a lot. I’m particularly please with the cracks in side the laundry. the attached pics don’t quite do them justice because they have closed markedly.

Thanks again.”

Chris, Terrey Hills, NSW. January 2020

“Thanks for helping us to fix the foundation problem and the teams was great to work with.”

“Great job, please do pass on my thanks to your team. I enjoyed meeting them and having a chat with them.

My neighbours also seemed pleased so a good job!”

Brian, Greenhithe, NZ. November 2019

“We would like to advise that we were extremely pleased with the service provided by Mainmark. From the first contact with P___, to the updates along the way until the job commenced. The staff who carried out the work today on our premises were very professional and polite. We are more than pleased with the service provided. We were well informed through the whole process as to what was required, and how the work would be performed. We came across Mainmark through a letter box drop and so pleased that we chose your company to proceed with. Thank you to everyone involved for a very professional job. Prompt, efficient and very polite.”

Leahrne, Tralagon, VIC. October 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
