What's involved in a replacement
A replacement is more than swapping a panel. The door, the springs, the track, the rollers and the opener all have to work as one system, and the installation is where that either happens or does not.
- Measure the opening, headroom, backroom and side clearance
- Specify the door, spring system and opener to suit the door weight
- Remove and dispose of the existing door and hardware
- Install, align and balance the new door on new track and rollers
- Test the counterbalance, the travel limits and the safety reversal
