He followed in the footsteps of his father and grandfather, who had a combined 85 years of experience in removing fungi, mold, and wood rot from thousands of crawl spaces over the many years they were in business. Mark, Sr. learned from his father and grandfather that the most important part of owning a business is to respect and be 100% honest to all of his customers.
