Why People Believe In Us

“It was our amazing good fortune to have found Marc Brien and his team at an hour of need.  

Parts of our home are over 100 years old with many modifications,alterations and additions over those years.   

We wanted, and got a builder who was ready to tackle all of the unforeseen work which had to be done in order to build us our dream home.  

This was an almost impossible project which Marc handled with grace and craftsmanship. Over a period of 1 1/2 years (with the major work done during the summers when the family was mostly at our beach house. Marc got the job done. He was always on the job. He was in constant contact with us , he helped us, he taught us and we created together the place we call home. There are always surprises in any renovation. His dedication to our family was unwavering. His desire to keep within the price point we had agreed upon was nothing short of amazing.  
Come see for yourself and we can tell you the whole story.  

PS: he also let me deliver his two gorgeous daughters. Marc Brien is a talented builder, a man of integrity.  

We started out as a builder and a customer. We are friends.......

“MDK has done numerous projects in my house over the past 10 years. Some examples of the projects they have done are a finished basement, tear down and re-construction of two bathrooms, new kitchen floor and granite counter-tops, and a full outdoor patio and fireplace. I have repeatedly used them since they are very good at what they do. The projects are done on time, within budget, and the workers are clean and courteous. The owner Marc Brien is very responsive, listens to the issues and addresses them promptly and in a courteous way. Whenever I have a home construction project or renovation, MDK will always be my first call and I would highly recommend them.”

“We used MDK construction for our home renovation in 2017. Marc and his team were very professional and more importantly completed the project on time and on budget. Marc’s experience helped guide us through what could have been a very stressful process. He was always available to answer our questions and concerns in a timely manner. His team was very easy to work with and extremely skilled in their craft. Marc suggested a number of great design ideas that we absolutely love. We highly recommend using MDK for your next home improvement project
