"Had an existing enclosed porch renovated. While reconstructing, had a few minor underlying issues that Derek and Joel, the two main persons on site, maintained professionalism; knowledgeable; and genuine with their craft. They provided an educational insight and how to remedy without 'gauging' the customer. Bill, Derek, and Joel very personable and looking out for the customer and then some. Highly recommend!"

"TNN managed our new construction and land development project from scratch. Tim caught MANY errors by the Engineer and Architect before they could become a problem. He made many great suggestions to elevate our original plans. Work quality is great and they take pride in everything they do. Nick did an amazing job on our trapezoid windows and carpentry work. We highly reccommed TNN and will continue to use them for the next phase of our project (garage) We would be happy to provide a reference and even show the work they completed for our project.

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
