I had an insulated door and jackshaft opener installed 3 years ago and already the door has sagged significantly in the centre. I have a heated garage, and because of the sagging door centre there is an approximate 1/2" air gap at the top of the door. As you can imagine the heat escapes rapidly in the winter and the heating bills are mounting. I contacted the company and they came to look at the door and insist that there is nothing wrong with it, but the service person told my wife he could install new weather stripping (at our cost) to seal the door tot he jamb again. My wife was also told that doors installed with jackshaft operators sag because there is no centre support on the door when it's in the open position. That would have been nice to know when this opener was recommended to us by the sales rep. Anyway, I don't think that adding more weatherstripping to a bowed door is an acceptable solution, the door will continue to bow and the exterior appearance will be odd because of the curvature of the horizontal weatherstrip bar. I spoke to the manager about my concerns after getting no where with the service manager and he promised to look into it and get back to me. It's been 3 weeks and no call back. Be warned, don't buy anything from these guys, it sure seems that they don't know their own products and don't really care about you after the sale.
