Common Questions

Frequently Asked Questions

How often should commercial garage doors be serviced?

Commercial garage doors should be professionally serviced at least twice a year. High-cycle doors in warehouses or loading docks should be inspected quarterly. Regular maintenance reduces emergency repairs by up to 80%.

What is the difference between sectional and rolling steel commercial doors?

Sectional doors open in panels along a track and offer better insulation — ideal for temperature-controlled environments. Rolling steel doors coil into a drum above the opening and require less headroom, making them better for warehouses and storefronts with limited clearance.
