Patio Door Sticks in Winter

Question:

My patio door is harder to close when it gets cold. I think it needs to be lubricated on the bottom. What kind of lubricant should i use?

Answer:

A patio sliding door often sticks in the winter because of changes in temperature and humidity that causes wood to move or expand. The frame, door, and home structural framing move. This movement also makes any lack of lubrication or dirt compound the problem.

You should clean the lower track with a vacuum, then wipe it down with a damp cloth. Follow the dampened-cloth with a silicon lubricant on the raised lip of the track. The silicone will lubricate the metal and limit dirt accumulation.

To properly lubricate the rollers, you will need to remove the door. You need to remove the top, inner stop that is normally screwed in place. Tip the top of the door in, then inspect, clean, and lube the top and bottom rollers. This is a two-person job, so have a helper.

You should also observe the operation of the door in the opening. If it’s rubbing on the track, then raise the door with the roller adjustment. If it’s rubbing on the top, lower the door. You might be able to solve your problem with a simple adjustment.
