Overhead doors we supply

  • Sectional overhead doors in steel, aluminum or insulated panels, which lift straight up and rest under the ceiling
  • Rolling steel doors that coil into a drum above the opening, for spaces with no ceiling room for tracks
  • High-speed doors for openings that cycle all day, like production lines and food plants
  • Insulated doors for cold storage and refrigerated warehouses
  • Fire rated overhead doors for buildings that need fire separation
  • Impact doors that can take a hit from a forklift and keep working

Installation

We start with a site visit and measurements, then confirm the door and operator with you. Our technicians install the door, program the operator and test the safety devices. We register the warranty when the job is done.

Repair and maintenance

We take emergency calls 24/7 and carry parts to fix most problems on the first visit. That covers springs, cables, drums, rollers, tracks, operators, photo eyes and loop detectors on most major door brands.

Maintenance can run quarterly, twice a year or once a year. Each visit covers lubrication, spring tension, hardware and safety device testing, and you get a written service report. See preventative maintenance for details, or loading dock doors for dock work.
