“The Duffek team was great to work with throughout our office build-out. They kept us updated on all progress and completed the project right on schedule. Their attention to detail was outstanding and we’re excited to be in our new space. I’d recommend the team for future projects-big or small-they were professional, trustworthy and motivated to create our perfect office space.”

Gary Scherper, Sherpers Inc.

“It was a pleasure working with Mike and his crew. They were always responsive to our needs and any problems that we encountered. We have had many compliments on the build-out of our Port Washington location.”

“It was a pleasure working with Mike at Duffek construction. Our Building was
done on time and within our budget. Hopefully we will have a need for his
services again in the future. Thanks for your great services.”

Jim Moody, Liberty Dance

“I was referred to Mike Duffek and his team after a horrible experience with another design build firm. Based on that experience, I thought we could never build within our budget. I was frustrated and about to give up! I was very candid with Mike that if we couldn’t complete the building within our budget that he should tell me straight away. Mike insisted it could be done!

In partnership with his architect, Mike and his team came up with a design that met our needs from a business perspective, was forward thinking, pleasing to the eye, and most importantly within in our budget! Mike was able to give us features that the previous builder said was not within our reach! I happy to say, that the project was completed in full, within budget. Along the way we’ve formed relationships that will last years.

If you have any questions, ask Mike for my contact info, I’m happy to answer any questions.”

President, CGM Financial Consulting

“Mike’s high level of integrity and strong communication skills make him stand out in a field where unfortunately this is often not the case. I worked with Mike for several years, and I watched him consistently bring in projects on time and on or below budget. Mike possesses extensive creative problem solving skills which allow him to develop solutions which other contractors wouldn’t be able to see.”

“We recently had Duffek Construction complete interior work in our medical facility as we converted to a Surgical Center. Mike remained involved throughout the process including ensuring we were meeting all applicable life safety codes for us to successfully pass our certification. They were very flexible with working outside standard hours so we could continue to care for our patients. The project was done timely, priced competitively and communication throughout and after the project was amazing. Our Surgical Center looks beautiful, I highly recommend Mike and his company!”
