We have used MSD Contracting for exterior work on 2 occasions, at our old house in Vaughan and 7 years later at our current Toronto home. We were very happy both times. The first job involved widening a driveway using interlock and the job turned out very well. We parked on it for over 5 years and there was absolutely no movement of the stones at all. When we moved to our new house, we didn’t hesitate to call MSD again for recovering an old concrete front porch/steps with flagstone. After many freeze-thaw cycles, there has been no issues with stones coming loose or popping of any of the mortar joints. On both occasions, Marco was very helpful with suggesting the best materials and actually went with us to pick out and purchase stones. As they are sought after for their work, you have to book ahead, but once they start the job, they don’t leave you hanging and finish on schedule. I have also recommended them to a few friends and everyone was very happy with their experience, the finished product and most importantly with how well their work held up over time.
