What Our Clients Say

Helene Lessard
Look no further, MCD Contracting Inc. can do the job! Our backyard needed quite a bit of TLC. We contacted 2 companies and within 24 hours, James from MCD Contracting was at our home to evaluate our needs and answer all our questions.
Bernice Pineau
We had our front patio done today and we are very pleased with the job. Clayton, Isa and their coworker were very professional and courteous. They completed everything to our satisfaction and done a great cleanup including sowing grass seed where needed. I would definitely recommend them.
Philip Black
Extremely happy with the work I had done. Job was done as planned, on time, no surprises, price was very competitive. Mike and James are great guys, local to the Russell area.

I have been an MCD client for many years. They have helped me with lawn maintenance, laying sod, patio installation, and driveway replacement. I have been extremely satisfied with their services!
Helen Brown
We called MCD Contracting to see if they could redo the top of the retaining wall around the pool. James, the business manager, picked up the phone. He came immediately to our home and gave us good quote, and persuaded us to go with their company to do the work. We were pleased with the prompt service.
Sarah Currie
James was very responsive to my initial inquiry, which I really appreciated after not hearing back from other services. Very easy to work with.
