Critical Safety

Immediate Danger Zones

High-tension garage components carry immense physical force. Review these urgent safety steps before our Derry dispatch team arrives at your home.

Broken Springs

Snapped Cables

Track Alignment

Do not attempt to pull the emergency release cord if your spring is snapped. The door can crash down instantly with extreme weight.

Loose or frayed cables can whip with lethal velocity. Keep children and pets entirely clear of the garage area until repairs begin.

Operating a crooked door burns out your opener motor and damages the track. Leave the door exactly as it sits to prevent further structural damage.
