What Our Clients Say

"Mike and his crew did an amazing job for us renovating our kitchen..."
"The job was done very quickly. We’ve had similar projects drag on for months but Mike wrapped this up in just over two weeks. These guys work hard and even worked through the weekend while we were away. We’re very happy with the results and we’ll be contacting them for more projects in the future."
— Chris J.
"Mike and his guys are 10 out of 10!"
"They completed my projects around my house, two weeks ahead of schedule and came in almost 20% under budget! When does that ever happen? If I ever build a new house would be my guy to do so! His guys have an awesome eye with attention to detail they leave no stone unturned."
— Joseph A.
"I hired Mike and his team for a full kitchen make over..."
"The team was meticulously careful during the entire process. I loved how I told him my vision once and he ran with it. I have lived through a kitchen remodel before without kids and was dreading it. I would do a kitchen once a year with this crew time and time again. Also super fast less than 3 weeks start to finish."
— Kristen C.
"We had a pipe burst a little over a month back..."
"603 Contracting came out immediately to assess the damage and worked extremely quickly to get my daughters room back in shape as most of her ceiling was gone. Within 3 days our home was back to normal."
— Sarah E.
"Mike and his team completely transformed our basement..."
"The guys did an incredible job, were respectful and communicative. High quality job for a very reasonable price. Mike himself was always responsive and personable."
