Ask them to install a new spring to compensate for the garage door's new weight. They'll have to bring a lever arm specifically for measuring the weight of the door, weigh it, and then make or order the spring. They aren't trying to screw you.
The springs on garage doors are supposed to be compensating 100% for the door weight. Additional door weight is only stressing the garage door opener and will cause it to fail much earlier than normal.
