 Trustindex verifies that the original source of the review is Google. I've had the pleasure of working with Mike and the team at Edge Construction Company for years, and they consistently impress me with their creativity, professionalism, and quality craftsmanship.

What sets Edge apart is their ability to think outside the box and bring unique design ideas to life. Their work is always top-notch, and it's clear they take pride in every project they touch.

Beyond the exceptional work they do, the entire team is wonderful to collaborate with—responsive, professional, and genuinely great people. They're also strong supporters of the Madison community, and I've seen firsthand the positive impact they've had through their involvement and support of local organizations and initiatives.

If you're looking for a construction partner that combines innovative design, outstanding execution, and a commitment to the community, I highly recommend Edge Construction

 Trustindex verifies that the original source of the review is Google. We finished our basement with the Edge Construction team. They were very helpful, fast, efficient, and professional from start to finish, helping us with every aspect of the project. We had a baby halfway through the construction and Edge was so accommodating and flexible with our schedule with a newborn - it was great not to have any extra stress at that time. They were also respectful of budget and gave us the cost up front. If we had another home project to tackle we would call Edge in a heartbeat.

 Trustindex verifies that the original source of the review is Google. We had Edge Construction install cabinets and custom shelves, a granite countertop, and a sink at our home in 2020. Erin was our designer and primary contact and she was very helpful throughout the process. While their free estimate ended up higher than some others we received, we were very impressed with their professionalism and responsiveness, and Edge worked with us to modify our project to fit our budget. Their contractors were also very good. I sincerely appreciated that the electrician they brought out to look at the job was honest enough to say that we didn't need him. The rest of the contractors we worked with were very knowledgeable and respectful of our home. We would definitely recommend Edge Construction!
