Garage door chain loose when closed.
Chain driven garage door openers should have some slack in the chain for optimal performance.
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.
Tightening up the slack on your garage door will allow it to run more efficiently and will prevent loud noises that disrupt your home.

Over time though this slack can increase or the gear and sprocket assembly can wear and the chain may pop off the sprockets.
Once you are clear that the only problem is a slightly loose chain then you can begin fixing the problem.
