    We have used Gen's Construction Co. for various home needs for over 10 years. He has performed home restoration on a variety of areas, upgraded a home for sale, and remodeled another. He was recommended to friends, who currently utilize his services to maintain a number of their rental properties. He performes his work up to his standards. You may say it's ok that way, but he will tell you it's his work---and anyone seeing his work, will see that it's right. He stays on it until it's perfect.
