What Our Clients Say...

"My wife and I hired MJay Builders to reside our house. Mervin and his crew came when promised and did an excellent job. Despite the fact that they began right when the first big heat wave of the summer hit, they were here everyday for a solid week. The amount of outstanding work they did in that time, despite the heat, is a small wonder to me. Beyond simply providing real craftsmanship, Mervin and his crew also gave my family and myself real peace of mind. I had no doubt that I could go to work in the sure and certain knowledge that the work would be done properly and as needed and that they would treat my property as if it were their own. When they were done, they did a thorough job of cleaning up, leaving my yard in a better state than it had been before. Hiring MJay Builders was definitely the best choice we could have made. If you want real craftsmanship and peace of mind at a fair price, MJay Builders are the right choice. I would happily show the work they did to anyone who asked."
