Frequently Asked Questions

We provide doors, frames, architectural glass, hardware, automatic operators, loading-dock equipment, locks, security and access control for commercial and industrial facilities. We treat every opening as a coordinated working system that must welcome people in, keep operations moving and protect what matters on the other side.

Yes. We work with brand-name doors and entrance systems from a range of manufacturers. Our technicians evaluate the complete opening—including the door, frame, hardware, operator and controls—to identify the source of the problem and restore safe, reliable movement.

Yes. Our planned maintenance identifies worn hardware, alignment problems and operator failures before they disrupt access, traffic or loading activity. By keeping the complete opening system working as it should, we help people, goods and operations move safely through the facility. We also provide corrective maintenance and 24/7 emergency service when an opening requires immediate attention.

Yes. When a standard product or dimension cannot meet the demands of an opening, we create a better way forward. We design and fabricate custom solutions around the facility’s architectural and operational requirements, including specialty doors as well as hangar and large-scale openings.

Yes. A fire-rated opening protects what matters only when the complete assembly performs as intended. We install, inspect, maintain and repair fire-rated steel, wood and glass doors, evaluating the door, frame, glazing, hardware and closing components that work together at this critical threshold. Applicable requirements vary by assembly, facility and jurisdiction.

Yes. Effective access control should welcome authorized people in, keep risk out and preserve a safe way through in an emergency. We integrate readers, electric strikes, magnetic locks, alarms and monitoring technology with new or existing opening systems while accounting for required egress, accessibility and fire-system interactions.

Setting a higher standard at every opening also means being clear about what’s covered after installation. Our installations include warranty coverage for products and workmanship. Specific terms can vary by product, manufacturer and project scope, so the applicable coverage should be documented in the proposal and project closeout materials.
