The Door Company

What The Door Company does

The Door Company (legal name: Door System Design, Inc.) is a privately held, family-owned garage door and gate installation and repair specialist founded in 1986 and headquartered in Chico, California. The company operates four physical service locations across Northern California — Chico (corporate headquarters), Yuba City, Redding, and Stockton — and holds contractor licenses in both California (496225-CA) and Oregon (189446-OR). It serves two primary customer segments: residential homeowners (garage door and driveway gate installation, repair, replacement, and emergency repair) and commercial businesses (commercial-grade overhead doors, fire-rated doors, high-speed doors, loading dock equipment, rolling steel doors, and automated gate systems), with secondary referral relationships with general contractors.

The company's product portfolio includes residential garage doors (aluminum and glass, steel carriage, wood and composite, stamped steel), commercial garage doors (coiling, curtain, hollow metal, fire, high-speed, counter, sectional steel/aluminum, impact traffic, partitions), driveway gates (swinging, sliding, four-fold, barrier), electric operators, loading dock equipment, bug screens, and smart Wi-Fi-enabled garage door openers. The company is an authorized dealer and factory-certified installer for major manufacturers including CHI Overhead Door Systems, Cookson & Clopay (CornellCookson), and Cornell side-folding grille systems. All services are delivered by IDEA-certified technicians using industry-standard equipment; the company has no proprietary technology platform and no AI/ML capability.

The business generates revenue through three streams: professional installation services (labor and installation fees), repair and maintenance services (billed per service call, including premium-priced emergency repairs), and hardware sales (residential and commercial doors, openers, and accessories). Pricing is quote-based and not publicly disclosed. Go-to-market is direct field service: customers contact the company via phone, email, or website forms to request quotes and schedule service. Marketing relies on website contact forms, Google Business listings with customer reviews, Facebook and YouTube social channels, and blog content for organic search. The company is led by President Mark S. Stuenkel (Chico) and Vice President/Sales Mark Cooper (Yuba City), with no venture capital, private equity, or institutional investor involvement.
