I have been trying to situate this issue for a while now and fixed one issue just to have another. I have a 16ft wide standard height garage door that keeps binding on the left side if your in the garage looking out. It use to be the second and third panel from the bottom would catch each other and POP when they were transitioning from the vertical track to the horizontal one. I put some 10ft struts across the door in the center and immediately the popping went away and all was good. After a few days now the popping is back only its between the first and second panel from the bottom now, same side. So far what I have done to try and correct. - Re-level door (unwind torsion springs and re-set cable tension) - measured tracks to make sure they were all same distance - Adjusted tracks vertically using a level - centered the garage door opener track with belt ( wasn't in line with center of door before. - Lubed all rollers and cables The door sits perfectly level when down however no matter how many times I have verified it being level I noticed when the door is in the up position the cable tension on the side that's binding has more than the other side. Not much but enough to feel it when touching the cables. Only other thing I can think of besides the cables still is the tracks need to come away from the opening a tad to allow more movement maybe so the panel can push out more when making the transition from the vertical track to horizontal. Is there a rule of thumb how much room the door panels should have when closed to the wall? Running out of ideas with this.

I'm having a garage addition and mudroom built this summer and just got the scope of work with project cost and payment structure. I was surprised to see that the builder want's a 50% deposit before beginning work, 50% when it is nearly complete, and the remaining 10% after final walk through. Is this pretty typical? It is a reputable company, so I'm not worried about the work getting done. I just thought 50% was a little extreme without having done anything but hand over the drawings so I can submit them to the county to obtain permits.
