When Your Doors Fail, Operations Slow Down

In New Castle, many commercial properties depend on reliable entrances to keep freight moving, employees safe, and customers flowing in and out. From warehouses near the Port of Wilmington to facilities along Route 273 and U.S. Route 13, door performance directly affects productivity. If an automatic door will not open during shift change or a loading dock door fails to close securely, it creates immediate disruption. Security is compromised. Traffic backs up. Tenants and supervisors want answers.

Del-Mar Door Service provides commercial door repair and automatic door service in New Castle with a focus on fast recovery and long-term reliability. Our technicians arrive with stocked service vans and the experience to diagnose problems quickly.

Built for Industrial and High-Use Environments

Industrial doors and high-cycle automatic entrances take constant wear. Distribution centers, manufacturing sites, municipal buildings, and retail centers in New Castle need doors that perform under pressure. We repair automatic sliding doors, swing doors, high-traffic entry systems, industrial doors, and security doors. Whether the issue involves sensors, closers, operators, hinges, or hardware failure, our team works to restore safe operation without unnecessary downtime.

24/7 Emergency Commercial Door Repair

Breakdowns do not wait for business hours. When your main entrance is stuck open after closing time or your secure access door will not latch properly, the risk increases. We provide 24/7 emergency commercial door repair in New Castle. Our dispatch team prioritizes urgent calls, and our technicians carry the most commonly required parts so many repairs can be completed immediately.

Maintenance Programs That Reduce Repeat Failures

If you are seeing the same door fail more than once a year, it is usually a maintenance issue. Wear components, loose hardware, and uncalibrated operators gradually lead to larger failures. Our preventative maintenance agreements include scheduled inspections, safety checks, adjustments, and part replacements. For industrial properties and multi-tenant buildings in New Castle, this reduces emergency calls and supports predictable budgeting.

A Different Standard of Service in New Castle

Many facility managers are used to waiting days for service, only to have a technician arrive without the necessary components. That leads to second visits and more downtime. Del-Mar Door Service operates with one of the largest service footprints in the region. Our technicians are highly trained and supported by more than 60 years of company experience. Each service vehicle is stocked with commonly used parts so we can address most problems on the first visit. Fast dispatch and preparedness are central to how we operate.
