Mitchell and the Substructure team did an amazing job on our exterior, building a new side wall, front wall, drive and front and back landscaping. I couldn't be happier. The number of complements we've received from neighbours has been incredible. The Substructure team was extremely courteous, helpful, showed up on time and finished the job on time. When questions arose, they always had good advice with options to choose from. Nothing but great things to say about the experience and value I received.

Mitch and team did a superb job of replacing a tired and crumbling parking area with an area that looks so smart. Mitch advised on products and layout, and the final result is far better than I expected. He also put in new drainage channels to ensure water will drain away properly, and not just sit leading to a build up of moss.
The work was carried out professionally, and the site left clean and tidy at all times.
I couldn't recommend Substructure more highly.
