Doug Fast

Doug Doug1Fast has completed over 7,500 inspections since 2003. Doug’s integrity and honesty is evident in how he performs inspections, how he markets his business, and how he communicates to clients. His inspections are extremely thorough and informative. Every client leaves the inspection knowing not only about potential concerns with the house, but also advice on day-to-day maintenance and how to operate house systems.

“As a home inspector, it is not only my job to thoroughly inspect the house for issues, but to educate clients on their new home, as well as identify positive attributes that already exist in the house, and what this means to them as home owners,” says Doug Fast.

With every inspection, clients will receive a detailed narrative report that is easy to read and contains photographs, as well as maintenance tips for the new home owners. Reports will be done in a timely matter, arriving to clients within the same day of the inspection. Clients will leave the inspection feeling like they hired a true inspection professional.

Doug also believes in giving back his time and serving others. One way Doug likes to do this is by volunteering with Habitat for Humanity on a regular basis.

“It’s so fulfilling being able to not only do what I love, but to also see the incredible impact of a community coming together to provide a new home for someone in need,” Doug Fast says of Habitat for Humanity.

He was nominated and selected to attend the United States Air Force Academy, where he was introduced to Colorado and met his wife, also a cadet. After graduating and completing their tours of duty, Eric and his wife returned to Colorado, where Eric pursued an apprenticeship as a commercial electrician, and later joined the Dumb Friends League, becoming Facilities Manager and later Director of Facilities, overseeing operations and maintenance of the organization’s commercial buildings and physical assets. Concurrently, Eric started and still runs his own property management business, focused on residential/commercial building repair and maintenance, energy efficiency, modernization, and project management.

Duston Busby
QBI Inspector

Duston hails from the small mountain town of Ruidoso, New Mexico, where he developed his skills in the home construction trades, along with an appreciation for the great outdoors. First as a carpenter for a homebuilding company, then a stagehand and ultimately maintenance supervisor for a theater company, he developed a keen sense for quality construction and an eye for detail, plus a thorough knowledge of mechanical systems. Concurrently, he took an interest in residential real estate, buying, fixing and selling homes, and managing a rental property. This experience motivated him to seek a career in home inspection and brought him to the Denver area as the newest member of the QBI team.

Duston has passed the National Home Inspector Exam and is a Certified Professional Inspector (CPI) with the International Association of Certified Home Inspectors (InterNACHI). When not inspecting homes, Duston enjoys skiing, hunting, camping, and applying his mechanical skills to restoring his 1969 Dodge Power Wagon. He’s an avid fan of the Denver Broncos and Colorado Avalanche.
