At Degenhardt Home Improvement, we know exteriors. since the mid 1970's, we have been beautifying homes in and around the Madison Area And it may come as a surprise to you but we do things differently. "We Transform Exterior Maintenance into Personal Freedom" and we use only the finest name brand roofing, siding, window and decking products to do it. Subsititutions of low quality material and sub-standard labor are simply not tolerated.
