We're happy to have helped

“I can confirm that C__ had a good experience working with Mainmark. The crew were good and experienced. We were briefed as to how they will proceed and were updated periodically. Monitoring around existing asset integrity/damage was good and gave us confidence. S___ signing on site digital and OHS procedures were satisfactory. The 12 mm lift was really amazing to achieve in a safe manner and a further assurance from the crew that a settlement should not happen moving forward was more than assuring.

Back End office support was quite meticulous and prompt. This helped us achieve tight timelines and C__ compliance.”

“Just wanted to give you the thumbs up on under pinning the corner of my house.

You, your office staff and the installation crew could not have been any more professional in the way executed the task at hand.

All was carried out with military precession, arriving dead on time keeping me abreast of the procedures and left the site clean and tidy.

I can honestly say job well done and recommend your services to people fearing how modern day underpinning works and is carried out.”

Ian, Clunes, VIC. April 2020

“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

“I can only say that we were over satisfied!  The professionalism, communication and courteousness from your staff was second to none.

We could not be happier with the finished result and can now finally commence our restoration works with confidence.”

Jasna & Wes, Keilor, VIC. January 2020

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