Wirth & Company did an excellent job renovating my home. They were efficient, had very skilled craftsmen, paid close attention to every detail, and were on time, on budget, honest, transparent, and in the end did a wonderful job that I could not have gotten done anywhere else. After having a bad experience with a different contractor once before, my luck changed when I met J.T. Wirth. They are an absolute pleasure to work with, are very experienced, knowledgeable, and trustworthy. The work that they did was excellent and I would highly recommend them to anyone.

When the building inspector did his walk-through before I closed on my new house, he commented that it was one of the best-constructed homes he had ever seen. That was certainly confidence inspiring. And it is indeed a rock-solid structure. But that is truly just the beginning. My girlfriend and I cannot say enough good things about JT and Derek. Small problems were corrected immediately, even those that we first noticed 18 months after closing! They never made us feel like we were bothering them; they were happy to help and proud to stand behind their work; and they always have smiles on their faces. And when it’s time for additions or improvements, there was/is no question about whom to call. We decided to have a state-of-the-art wine cellar installed, and we went straight to Wirth. Derek did a masterful job on a project that was logistically difficult, and the final product turned out to be absolutely perfect. Outstanding builders. Pleasant, trustworthy, and accessible people. We couldn’t ask for more.

Working with Wirth & Co. was an experience unlike any I have had in the past with a home builder. Jonathan and his crew performed meticulous, thorough work and manages to exceed my expectations from a craftsmanship aspect. His prompt communication and follow through made renovating my home an enjoyable and clear sailing process for me and my wife. I would highly recommend Wirth & Co. and their crew!
