I've had the experience of purchasing 2 new homes in the past year. One from mjc and one pultie. Being a smaller company I thought mjc would be hands down a more responsive company, that is not the case. I am displeased in a few aspects but primarily the lack of communication on 5 of the 6 cat 6 connection I paid to have installed. 5 of the 6 were not wired correctly. Att charged me to replace and rework the connections properly. The contractor who installed them did so improperly and did not test them. I'm waiting for my response and 3 emails. I'm also not happy with the attitude of your field supervisor. The people who work under him are great. I met with this man once and that was enough. I'm not the only one who feels this way. So I don't expect to hear from anyone and that will only solidify my thoughts on mjc.
An Overall great experience! Quality work, quality materials, excellent communication, and very easy to work with. They provided an opportunity for us to build our house(without a construction loan) and we didn't have to sell our current home until we were ready. We're very happy with the results!
