Knowlegeable, honest contractor and crew. They come on time, work dilligently, finish promptly and the work is reliable. They do not dwell on minute attention to perfection, rather do what a contractor should, they are not decorators. Price is fair, workmanship professional. I would recommend this contractor and his crew.
