Worn or flat spotted rollers on the bottom of the sash cause drag and can be replaced as a separate part. Many wood window models use adjustment screws at the sash ends that raise or lower the rollers to correct a sash that rubs the track. A double pane unit will not fix a mechanical drag. Salt spray from batiquitos lagoon accelerates roller corrosion. Replacing the roller restores smooth travel.

Weep Hole Maintenance

Clogged weep holes in the sill trap water in the track and standing water with salt can corrode rollers and hardware. A clad window sill should be cleared with a thin wire after each storm. The marine layer brings persistent moisture that keeps weep holes damp. Traffic on interstate 5 kicks up fine sand that finds its way into the track. Clearing the holes keeps drainage working.

Over-tightening can bend the roller axle and create a new bind. Use a small open-ended wrench to avoid stripping the head. Proper adjustment eliminates the rub that causes drag.
