    “Outstanding Work”

    Yesterday George and his wonderful team of workers did a roof replacement on my house. They did a superb job. I was very pleased with the quality of work on my roof. After the job was done they did an amazing job of cleaning up which left my property spotless. I hired George on the spot after discussing the job and estimate with him. He’s an honest contractor who delivers what he promises. I would recommend George in a heartbeat.
