  • “Mike always stood by his word and always found a solution...”

    Linda and JP Chauvin (Custom Home Build)
    Building our retirement home with Mike Dunn Construction was definitely the right choice. We began the project in November 2009, and moved into our new home by early May. Working with Mike and his team was less stressful than selling our previous home! We always knew what to expect next, and knew where we stood with respect to the original construction budget. Except for a few days over the winter holidays, there were tradesmen on site every single day. Many of our neighbours commented during construction about the neatness of the site. Mike always stood by his word and always found a solution to any issue we had after construction was completed. We have lived in our home for seven years now and love everything about it – including the excellent quality and workmanship.
  • “He was a pleasure to work with from day one…”

    Dave Zimmermann (Custom Home Build)
    We contacted Michael Dunn to build our custom home and he was a pleasure to work with from day one at the drafting table, right up until occupancy. Mike and his entire crew worked with the upmost efficiency, keeping safety in mind, and not slacking at all with the meticulous details toward the end of construction. Any questions or concerns during construction were taken care of immediately, building our confidence in Mike even more. I would highly recommend Michael Dunn Construction to others, and would definitely use them again for any future projects. Thanks Michael Dunn & team!
  • “His ability to manage the budget, schedule, and quality of the construction of our new home was excellent.”

    Mary Anne Milligan (Custom Home build)
    We are very satisfied with our decision to select Michael Dunn Construction as our general contractor for the construction of our new home. Mike does an exceptional job as a project manager. He managed this new build starting at the architectural design right through to the final inspection. His ability to manage the budget, schedule, and quality of the construction of our new home was excellent. Mike took the time to answer all our questions and provided us with options during the project. Mike’s crew is always professional and have ample experience. They take the time to build a quality home and never cut corners. We are very happy we had Michael Dunn Construction Ltd. build our dream home!
  • “His knowledge of construction requirements and his attention to detail are unbeatable…”

    Wayne and Judy (Historic Home Addition + Renovation)
    We’ve renovated many houses with different contractors over the years, but Mike Dunn Construction sits at the top of the list. Mike provided us with a 1000 sq. ft. addition and many upgrades to our 1908 farmhouse and handled it all effortlessly. From old wiring to new heating, his knowledge of construction requirements and his attention to detail are unbeatable. His employees are great: easy to work with, fast, efficient, clean and courteous. A joy to have around. Once the project was finished, we missed them. Mike supervised the project thoroughly, keeping the trades on time and the mess to a minimum so that we could easily live in the house while the work progressed. Most importantly, the quality of the work was always to code with no corners cut. Safety and energy efficiency came first with all the contractors that installed heating, plumbing and electrical. We received first class workmanship from framing to trimming out. Friends and neighbours who came to our housewarming party and viewed the finished product a few weeks later said we should be on the house tour! Would we hire Mike again? Every time.
