help1. Understand the Problem

Solid wood drawers expand and contract with humidity changes. In humid climates or summer months, the wood absorbs moisture and swells, making the drawer fit too tightly in the opening. In winter, it contracts and may have gaps. This is normal wood behavior, not a slide or construction failure.

Best First Step

Reduce the humidity in the room and try the drawer again

Run a dehumidifier in the room for a few hours. If the drawer starts to move freely after the humidity drops, you know the issue is environmental, not mechanical. Room humidity above 60% will cause wood to expand noticeably.

Plane the drawer sides slightly where it bindsIdentify where the drawer binds - it will be tight at one or two points along the side. Mark those spots with a pencil. Use a hand plane or a surform tool to shave a thin layer (1/32 inch) off the drawer side at those points. Check often - take a little off and test, then take more if needed.

Sand the binding area smooth and seal the exposed woodSand the planed surface with 120-grit sandpaper to smooth it. Wipe with a damp cloth to raise any wood grain, then sand lightly again. Apply a coat of primer or sealer to the bare wood - this prevents the drawer from absorbing moisture from the air at the same rate as the finished surfaces.

Apply paste wax or furniture glide to the drawer runnersOnce the drawer moves freely, apply paste wax to the slide runners on both sides of the drawer and the cabinet track. This reduces friction and makes the drawer slide smoothly even when there is slight swelling. Reapply twice a year in humid climates.

Add a furniture glide to the bottom corners of the drawerApply adhesive felt or PTFE furniture glides to the bottom front corners of the drawer. These reduce the contact surface and allow the drawer to slide even when the wood has swelled slightly. They also protect the floor.

air
Keep the room at 40-50 percent humidity to prevent recurring swellingUse a humidistat to monitor room humidity. If it stays above 55% in summer, run a dehumidifier. Keeping the humidity stable prevents the seasonal swelling cycle that causes drawers to stick.

Frequently Asked Questions

Why does my drawer only stick in summer?expand_more
High humidity makes solid wood expand. The drawer absorbs moisture from the air and swells, making it too tight for the opening. This is completely normal wood behavior and not a defect.
Should I sand the drawer or the cabinet frame?expand_more
Sand whatever is binding. Usually it is the drawer side - mark where it is tight and sand that area of the drawer. If the cabinet track is the problem (less common), sand the track. Test fit after each pass.
How do I prevent the drawer from swelling again?expand_more
Seal the bare wood where you sanded. Keep the room humidity at 40-55% with a dehumidifier in summer. Apply paste wax to the runners regularly. These steps together prevent recurrence.

warning5. Stop DIY If

Don't continue if any of these apply.

reportThe drawer is particle board, not solid wood - planing it will destroy the surface. Replace the drawer or line it.
reportThe swelling is so severe the drawer has cracked or delaminated - the drawer is damaged beyond adjustment.
reportThe binding is at the front, not the sides - the drawer front may have shifted due to loose hinge screws at the top.
reportThe drawer sticks in winter but is fine in summer - this is the reverse problem (too dry). Use a humidifier.
