About Dabella
DaBella was founded in 2011 in Portland, Oregon, by Donnie McMillan Jr., who named the company after his children, David and Isabella. From its beginnings as a small family-owned business, it has grown into one of the largest residential home improvement companies in the United States. Today, DaBella operates more than 60 offices across over 25 states and employs thousands of people nationwide. The company specializes exclusively in replacement services rather than repairs, focusing on roofing, siding, windows, and bath and shower remodels. Its roofing division holds the distinction of being a GAF Master Elite Contractor, an award earned by only a small percentage of roofing companies nationwide, and has also received the GAF President’s Club Award for excellence in installation and customer satisfaction. In siding, DaBella is a James Hardie Elite Preferred Contractor, offering high-performance fiber cement siding along with vinyl and composite options designed to protect homes and improve curb appeal. DaBella also provides professional window replacement services, installing energy-efficient vinyl windows that enhance comfort and reduce energy costs. In bathrooms, the company offers low-maintenance acrylic bath and shower systems through Sentrel Bath Systems, designed for durability, style, and easy upkeep. With a direct-to-consumer business model, DaBella eliminates retail intermediaries, allowing homeowners to work directly with trained specialists who provide consultation, design, financing, and professional installation. All products are backed by industry-leading warranties, giving customers confidence that their investment will last. Driven by its family-oriented culture, commitment to quality, and partnerships with top manufacturers, DaBella has established itself as a trusted contractor for homeowners across the country who want lasting improvements built with professional craftsmanship.
