We have been inspired and impressed with the leadership and team work that Konell Construction has offered us while we were in the building phase of our space. Konell staff has brought technical and sound building advice and the suggestions have helped us problem solve some difficult negotiations with various inspectors and the building owner. The Konell team has worked well in teaching the youth that have joined the work days. This direct collaboration has helped several young people become job ready, have job skills, and manage life skills to be successful.

I would like you to know that I appreciate all the hard work and extra time that Mike and his crew has put into the parking lot to make it look so good and getting it done on time. It’s getting harder and harder to find people who take pride in their work and make the extra effort. This is a trait that I have seen throughout Konell and it’s been my pleasure to work with you guys.

It is my opinion that Konell Construction is the finest earthwork, utility and demolition contractor in our area. From pre-construction to close-out, Konell is a valued team member and asset to our construction projects. They have always provided quality work at a fair price, done safely and on time. Konell Construction & Demolition is a great value and exemplify quality contracting through customer service.
