Kinship

What Kinship does

Kinship (legal name Kinship Door and Hardware Solutions LLC) is a privately held, vertically integrated commercial door, frame, and hardware solutions provider headquartered in Auburn, Washington. The company was formed in 2021 through the merger of Contract Hardware and Evergreen Construction Specialties, combining 70+ years of combined industry presence and 200+ years of staff experience across design, manufacturing, sales, distribution, installation, and ongoing facilities maintenance. Its service portfolio spans five interconnected lines: design and architecture consulting, commercial construction services (Division 8), building maintenance and locksmithing, multi-family pre-hung unit production, and in-house manufacturing of wood and hollow metal doors and frames. The company distributes products from more than 40 manufacturer partners, including Allegion, Assa Abloy, and Dormakaba brand families, and offers specialized solutions such as high-security master key systems, electrified access control, LEED-certified doors, and lead-lined healthcare doors.

Kinship serves a diversified mix of enterprise and institutional customers across retail, technology, government, healthcare, education, and hospitality sectors. Named customers include Costco (national account), Amazon (Seattle HQ towers and office campuses), Scheels, F5 Networks, the U.S. Army Corps of Engineers, St. Michael Medical Center, Sammamish High School, and Sundance Resort. The company operates primarily in the Pacific Northwest, with expanding footprint across the West and Central United States driven by multi-state rollouts for national retail accounts.

Kinship's business model is project-based and quote-driven, with revenue generated from hardware product sales, pre-installation services, on-site installation, ongoing facilities maintenance, and design/specification consulting. GTM is enterprise field sales executed through direct relationships with general contractors, architects, engineers, facilities managers, and dedicated national account teams. Pricing is custom per project and is not publicly disclosed. There is no evidence of external venture or private equity ownership, and Kinship operates as an independent, founder/operator-led specialty contractor.
