Dover & Company

What Dover & Company does

Dover & Company is a family-owned home improvement business headquartered in Flint, Michigan, founded in 1936 by Wilfred C. (Bill) Dover and operated continuously across multiple generations. The company sells and services residential and commercial exterior building products — garage doors, garage door openers, entry doors, patio doors, windows, vinyl siding, and seamless gutters on the residential side, and sectional doors, rolling steel doors, commercial operators, loading docks, dock levelers, hollow metal doors, and bathroom partitions on the commercial side. It operates four showrooms in Flint, Saginaw, Lansing, and Pontiac and dispatches factory-trained technicians across Mid-Michigan for installation, same-day repair, and 24/7 emergency service.

Revenue is generated through a mix of one-time product sales, bundled professional installation, recurring repair and maintenance services, and a small e-commerce channel for parts and accessories. Pricing is predominantly quote-based, with select published anchors such as patio doors starting at $2,999 installed. The customer base spans residential homeowners, new-construction builders, and commercial/industrial businesses across Mid-Michigan. A proprietary Dover Mobile App supports commercial service scheduling and technician tracking, and commercial operators integrate with Chamberlain's myQ Facility software for smart monitoring — features that are connectivity-driven rather than AI-native. In April 2026, Dover entered a partnership with Guild Garage Group under which it retains unit-level ownership, receives annual distributions, and is positioned for an eventual full exit as part of a national consolidation strategy.
