Commercial Entrance Systems
Expert installation, repair, and maintenance of commercial automatic sliding doors, operators, and sensors. We service all major brands including Besam, Dorma, Stanley, and Record across the DC, Virginia, and Maryland metro area.
Door Systems
From standard bi-parting sliders to hermetic hospital doors, we install and service every type of commercial automatic door system.
Single-slide, bi-parting, and telescoping configurations for high-traffic commercial entrances. Smooth,
Low-energy and full-energy swing door operators for interior and exterior applications. ADA-compliant with adjustable opening force, speed, and closing delay.
Space-saving automatic folding door systems for narrow openings and vestibules. Panels fold to one side, maximizing clear opening width in tight spaces.
Wave-to-open, proximity, and radar-activated entry systems for hygiene-sensitive environments. Hospitals, labs, food service, and clean rooms.
Airtight automatic sliding doors for hospital ICUs, operating rooms, and clean rooms. Hermetic seals maintain positive or negative air pressure zones.
Automatic sliding doors with breakaway panels that swing open for emergency egress. Required by fire code for automatic sliding doors on emergency exit routes.
Engineering Detail
An automatic door system consists of a motor-driven operator, track assembly, sensor array, controller, and glass door panels working together to provide hands-free, ADA-compliant building access.
A brushless DC motor in the operator header drives a toothed belt that moves the door panels along the track. Variable-speed controllers allow precise adjustment of opening speed, closing speed, and hold-open time.
Microwave motion sensors detect approaching pedestrians and trigger the door to open. Infrared presence sensors in the door frame detect anyone standing in the opening, preventing the door from closing on a person.
The electronic controller processes sensor inputs, manages motor speed, monitors safety devices, and stores programmable settings. Most modern controllers support lock integration, fire alarm tie-in, and remote diagnostics.
Precision-machined aluminum track with ball-bearing carriages provide smooth, quiet door movement. The carriage connects to the drive belt and suspends the door panel from adjustable hanging brackets.
Safety beams, presence sensors, and anti-finger-trap guards work together to prevent entrapment. The system meets ANSI/BHMA A156.10 for powered pedestrian doors and ANSI A117.1 for accessibility.
Sliding panels on emergency exit routes include breakaway hardware that allows the panels to swing outward under push pressure, creating a clear egress path during fire alarm activation or power failure.
Applications
High-traffic entrance systems for malls, big-box stores, supermarkets, and retail chains. Bi-parting sliders handle heavy pedestrian flow.
Lobby and vestibule automatic doors for corporate offices, multi-tenant buildings, and coworking spaces. Integrated with access control systems.
Touchless entry, ICU hermetic doors, and hands-free access for sterile environments. Critical for infection control and patient accessibility.
Grand entrance sliders, bell desk access, and banquet hall dividers. Quiet operation and elegant finish for hospitality environments.
High-speed automatic doors for terminal entrances, security checkpoints, and boarding areas. Engineered for extreme cycle counts.
ADA-compliant entrance systems for courthouses, libraries, DMV offices, and municipal buildings. Often integrated with security vestibules.

Common Questions
We service and install all major automatic door operator brands including Besam (ASSA ABLOY), Dorma, Stanley, Record, Nabco, Horton, and Tormax. We carry common replacement parts and can source OEM components for any manufacturer.
Yes. The Americans with Disabilities Act requires that automatic doors meet specific standards for opening speed, hold-open time, force, and clearance. ANSI/BHMA A156.10 governs power-operated pedestrian doors. We ensure every installation meets these requirements and can retrofit existing doors for ADA compliance.
We recommend professional maintenance every six months for high-traffic automatic doors and annually for moderate-traffic locations. Regular service includes sensor calibration, track cleaning, belt inspection, motor lubrication, and safety device testing.
Yes. We replace broken or damaged glass panels in automatic sliding doors without replacing the entire door system. We match the existing glass type and install the new panel with proper gaskets and seals. Most glass replacements are completed the same day.
Common sensor types include microwave motion sensors, infrared presence sensors, pressure mats, and push-button or touchless wave switches. The sensor type depends on the door location, traffic pattern, and security requirements.
A standard automatic sliding door installation typically takes one to two days. This includes mounting the operator header, installing the track and door panels, wiring sensors and controls, and performing safety testing. We schedule most installations during off-hours.
About Automatic Doors
Commercial automatic doors are a critical component of modern building access. They provide hands-free entry for ADA compliance, manage pedestrian traffic flow, contribute to energy efficiency by minimizing open-door time, and enhance the professional appearance of your building entrance. In the Washington DC metro area, where commercial buildings serve hundreds or thousands of visitors daily, a reliable automatic door system is essential for both safety and operations.
The Americans with Disabilities Act requires that public accommodations provide accessible entrances. Automatic doors satisfy this requirement by eliminating the need for manual door operation. ANSI/BHMA A156.10 governs the performance of power-operated pedestrian doors, specifying opening speed, closing speed, hold-open time, breakout force, and safety sensor requirements. We ensure every automatic door installation meets these standards and can retrofit existing manual doors with automatic operators for ADA compliance.
Expert Glass Repair has installed and serviced commercial automatic doors across the DMV for over 20 years. We work with all major operator brands -- Besam, Dorma, Stanley, Record, Nabco, Horton, and Tormax -- and carry common replacement parts for fast repairs.
