"We recently hired Harmony to replace our roof and install vinyl siding and new gutters. Our experience with Harmony was exceptional. The quality of work was top notch. Dennis kept us informed of every aspect of the job. He was always available (24x7) to answer question and continually stopped on-site throughout the job to inspect progress and insure we were satisfied. Most importantly he is honest and caring; a quality sometimes absence in the home improvement business. I am happy to recommend Harmony Home Improvement."
