Our Commercial Process
Sullivan Entry installs commercial steel doors with a focus on security, safety, and durability. Their process starts with a site visit to measure and check for building code requirements. If needed, old doors and frames are removed. New steel doors and hardware—like locks, closers, and panic bars—are then carefully installed to ensure they open and close properly. Their skilled team handles everything from fitting the frame to final adjustments, making sure the doors work well and last a long time.
