“J______ and his team, T_____ and L____, attended today and carried out the foundation support works as you specified.
J______ professionally directed his team and their obvious respect and trust in each other enabled them to perform the job to a high level of precision.
T_____ and L____ were very friendly and informative despite me hanging around their equipment and asking questions etc.
The crew achieved an impressive degree of lift with no noticeable affects on the integrity of the slab; the wall cracks closed up immediately and the sliding windows and sliding door no longer jam.
Please pass on our thanks to J______ his team.”

The crew from Mainmark commenced works on Tuesday 16th through to Friday 19th February 2021.  Your supervisor S____ and his crew were absolutely amazing.  Both professional and respectful of my home.  They were extremely courteous and cleaned everything as they went along.

They were courteous and respectful, went about their work with a great deal of professionalism, and were very approachable. As the homeowner looking for a successful outcome their way of working made me very glad to have them on site. G__ in particular did an incredible job leading the team and engaging with me during the day as I had questions or we needed to make decisions about next steps in the process.

Couldn’t recommend the team more highly – please feel free to pass on to whoever is up the chain so they know how very happy I was to have had them here.”
