Meet our President, Pat Jewell
Pat, a Bowie, Maryland native, started his career in the roofing industry in the 1980s and quickly developed a passion for enhancing people’s homes. In 2010, frustrated with high-pressure sales tactics and poor customer service in the industry, he founded his own company.
Since then, Capitol Improvements has expanded to serve thousands of clients with a wide range of services, always prioritizing customer needs. Pat’s two sons, Austin and Lance, now help carry on the family legacy, working with a dedicated team to continue building strong relationships and delivering exceptional service.
