Konell has and continues to provide a high level of professional service that I can confidently say is "best-in-industry" relative to their local competition. I've used other demolition companies in the past, but Konell is by far the best. I highly recommend you use them for all of your construction and demolition needs, I know I will!

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.

They all exemplify the true meaning of the words “partner” and “teamwork,” which are invaluable attributes to possess as contractors. The most notable differentiating factors that I have observed about Konell Construction are that they are solution-oriented in how they approach project challenges and that they approach every project relationship with the highest marks of honesty, integrity and professionalism. I have yet to meet anyone at any level of Konell Construction that does not exemplify those same attributes that make them such a pleasure to work with.
