Del-Mar Door Service

What Del-Mar Door Service does

Del-Mar Door Service is a regional commercial and automatic door service provider operating exclusively in Delaware across 14+ communities including Wilmington, Dover, Newark, and Middletown. The company is a regional operating entity within the Door Services Corporation and Horton Automatics network, the latter founded in 1960 as the inventor of the first automatic sliding door. Del-Mar delivers a full lifecycle of door services — installation, on-site repair, preventative maintenance, fire door inspections, and 24/7 emergency response — staffed by AAADM-certified technicians dispatched in fully stocked vans capable of completing most repairs on a single visit.

The product portfolio spans automatic sliding, swinging, folding, and revolving doors; fire and security entrance systems; Won-Door fire door maintenance; and manual door service through authorized distributor relationships with multiple manufacturers. Verticals served include healthcare (revolving entrance, ICU, and hospital room doors), education, retail, senior living, hospitality, industrial, security, and cleanroom applications. The offering is supported by a preventative maintenance contract program that the company claims delivers 25% cost savings versus reactive repair.

Revenue is generated primarily through professional services (installation, repair, inspections, emergency work) complemented by a recurring maintenance contract stream. Pricing is quote-based and not publicly disclosed. Go-to-market is direct field service, with phone (800-492-2392, 833-671-8777) and website contact forms as the principal conversion channels, and downloadable eBooks/whitepapers used as mid-funnel lead capture. No revenue, headcount, or financial disclosures are publicly available, and the company is privately held under its parent structure.
