Your Sliding Door Tune up Guide

Remove the Door

Clean and Grease Tracks and Rollers

Gently remove each roller from the pocket in the bottom of the door; it’s easier if you used a flat head screwdriver. Replace the rollers if they are worn out or bent; they cost $10 or less. Remove dirt from the wheels and use alcohol to clean them. Use silicon spray to grease the rollers; silicone spray is preferred because it doesn’t hold dirt. Replace them by placing each roller adjustment screw with its entry hole and tap in the assemblies with a hammer.

Once they’re positioned, pull back the rollers. Use alcohol to clean the head track and the head stop then grease it using silicone spray. Use a stiff brush to remove debris from the bottom track, and then clean it using denatured alcohol. It’s unnecessary to lubricate the lower track but if you have to, you can rub it a little with a block of paraffin wax.

Weatherstrip and Reinstall

Examine the weather stripping to check if it’s torn or cracked. Using a flat head screwdriver, back out the screws, hold one end and pull it off the door. Use pliers to pull out the remaining staples and then use a hammer to flatten the broken ones. If you want to replace the strip on the jamb side, hold one end and pull it off. This strip is usually glued; therefore, you need to use a putty knife to remove the remaining part. Ensure that you do it gently to avoid scarring the finish.

At the point where the sliding panel frame overlays the fixed panel, align the stripping with the flap facing the direction indicated on the instructions. Position the top end with the shadow line of the head stop and then fasten the internal ridge along the door’s edge. Drill a 1/8 inch wide hole adjacent to each of the holes on the internal ridge and drive the screws. Repeat the same process on the fixed panel so that the strips interconnect. Use the plastic adhesive to glue the jamb side strip. If there are any blotches or fingerprints on the panel, you can use alcohol to clean it up.

Place the door on the bottom track and incline it upwards. Use your body to support the door and then fix the head stop. Roll the door and make sure that it stands parallel to the jamb. If the latch does not match to the receiver on the jamb, tune the receiver by loosening the screws and turning it clockwise or counterclockwise.

If you follow these steps and your door doesn’t slide smoothly, it may be due to a construction problem or poor positioning. You can hire a contractor to check your door and have the problem fixed.
