Interlock, natural stone, flagstone, driveways, backyards and entryways are our specialty. We pride ourselves on ensuring each project is completed properly the first time, so that you won't waste time or money with return visits or costly repairs.

We understand that balance between hardscaping (stone) and softscaping (greenery) is important when designing a stunning outdoor space, so we also provide sodding and greenery services and work with many local suppliers in the Greater Toronto Area.

One of our most popular services is repairing interlock and stone work that other companies have not completed properly.

We offer many services in addition to our primary ones, from retaining wall and deck construction to driveway paving.

Our clients

From projects both big and small

"We needed a backyard patio completed before a party we were hosting and had no idea where to start. Michael came, gave us some suggestions and he and his staff completed it with plenty of time to spare. We were impressed then with their work, but even more so now, 8 years later because it's still perfect. Even the magic sand hasn't needed to be reapplied!"


"I am a firm believer that you get what you pay for but I think in Michael's case, I believe I got more than I paid for! The quality is amazing. After 7 years, our extensive stone work did not shift or sink. All of his staff are hard workers and take care in doing the job right the first time. Michael gave us great suggestions for stone selection that helped us stay within our budget and also with selecting trees and flowers. They came, completed their work in a timely manner and cleaned up before they left."


"Because it was such a big investment, (we have a big backyard), we wanted to be sure we hired the right contractors. I am extremely happy that we chose MSL because I have seen other people's patios and they are nowhere near as good as ours."


"Needed to get my driveway repaved but decided to do interlock instead. Also made my driveway bigger so I can fit more cars. Michael helped me pick stones and to decide on a design for the extended part. I watched him and his crew some of the time and saw them really making sure everything was done properly. Highly recommended."


"Our backyard is like paradise now. Before the work, we never go there. Now we go out almost every day to sit and talk or BBQ. Beautiful and good work!"
