It might be that the screws holding the drawer runners into place have become loose over time and need re-tightening. Sometimes it is a case of removing the drawer and simply tightening the screws. However, you may find the holes have grown too big to hold the screws effectively due to movement over time.
EMPTY
As before, empty the drawer and lift out the drawer from the runners.
EXAMINE
Examine each hole where there is a screw. You will be able to see if the screw no longer fits. As a result of constant movement over time, the holes for the screws may have stripped.
REMOVE
Using a screwdriver, remove all the screws and the tracks from the drawer after checking which holes need repair.
WOOD GLUE AND MATCHES
Make sure the holes remain free from dust. Squirt a little bit of wood glue into the hole. Snap off the heads of the matches and insert the matches into the hole. However, you may need to put in up to three matches to fill the hole successfully. Hammer the matches in gently to make sure they form a very tight fit.
DRYING
Allow the glue to dry, which may take an hour or so. Once dry, use the utility knife to cut away the excess matches sticking out of the holes. You are aiming for as flush a finish as possible.
ASSEMBLE
Now it is time to reassemble the drawer runners. You should find that the repaired holes will now take the screws quickly and firmly. However, ensure each screw fits tightly into position.
Check the screws on the tracks of the carcass. Make sure each screw is firm and that the track does not wobble. Repeat the process on the tracks in the carcass if necessary.
Your drawers should now move freely and feel like new.
