Step 2 turning off the power.
Garage door chain loose when closed.
If your garage door chain needs to be replaced tightened or if you require any other garage door maintenance or repair work count on the technicians at creative door services.
If in doubt replace the chain completely.
A loose garage door chain has less power to open and close the garage door and it can often create a loud and annoying sound as the slack hits the door.
Chain driven garage door openers should have some slack in the chain for optimal performance.
Over time though this slack can increase or the gear and sprocket assembly can wear and the chain may pop off the sprockets.
Make sure that the garage door is closed and that you have another way of getting out of the garage.
Tightening up the slack on your garage door will allow it to run more efficiently and will prevent loud noises that disrupt your home.
