A drawer that sticks, drags or jams halfway is one of the most common furniture annoyances, and it usually gets worse if you keep forcing it. The good news is that most sticking drawers have a simple cause: humidity, dirt, a loose screw, a misaligned slide or too much weight. This guide explains how to fix sticking drawers on wood runners and metal slides, step by step, and how to keep them gliding smoothly.
Why Drawers Stick
| Cause | Signs | Fix |
|---|---|---|
| Humidity swelling | Sticks in summer, fine in winter | Lower humidity; wax runners; sand high spots |
| Dirt or debris in the track | Gritty feel, catches at one spot | Vacuum and wipe the runners |
| Dry wood-on-wood runners | Drags along its whole length | Rub with paraffin wax or a candle |
| Loose screws | Drawer wobbles or drops at one corner | Tighten slide and runner screws |
| Misaligned slides | Rubs on one side, won't close flush | Loosen, realign and retighten |
| Overloading | Sags, scrapes the frame below | Remove weight; respect the capacity |
| Sagging or loose drawer bottom | Bottom drags on the frame | Re-seat or support the bottom panel |
| Worn or bent metal slides | Grinding, rollers skip | Replace the slides |
What You'll Need
- Screwdriver
- Vacuum with a crevice tool
- Microfiber cloth
- Paraffin wax, an unscented candle or a bar of dry soap (for wood runners)
- Dry silicone or PTFE spray, or the lubricant the slide maker recommends (for metal slides)
- Fine sandpaper (150–220 grit), only if needed
- A pencil or chalk to find rub marks
Step 1: Empty the Drawer and Take It Out
Remove everything from the drawer, then take it out. Wood-runner drawers usually lift out once fully open. Many metal ball-bearing slides have a small lever or tab on each side that you press to release the drawer; side-mount roller slides often lift out at the end of travel. Check the manual if you're not sure.
Step 2: Clean the Runners and Tracks
Vacuum the drawer opening and the tracks, then wipe the runners with a dry or barely damp cloth. Crumbs, dust, a stray sock or a coin is often the whole problem. Look for anything caught at the back of the opening, too.
Step 3: Tighten Loose Screws
Check every screw on the slides, runners and drawer box. A loose slide lets the drawer drop and rub. If a screw spins without tightening, the hole is stripped: fill it with wooden toothpicks dipped in wood glue, snap them flush, let the glue dry and drive the screw again.
Step 4: Lubricate
Wood runners: Rub paraffin wax, a plain candle or a dry bar of soap along the runners and the bottom edges of the drawer sides. Avoid oils and grease on wood; they soak in and attract dust.
Metal slides: Clean them first, then use a light dry lubricant such as silicone or PTFE spray, or whatever the slide maker recommends. Wipe off the excess so it doesn't collect grit.
Step 5: Check the Alignment
Slide the drawer in slowly and watch where it catches. Rubbing chalk or pencil on the drawer edges will show the contact spots. If one slide sits higher or further forward than the other, loosen its screws, adjust it so both sides are level and parallel, and retighten. Many slides have slotted holes for small adjustments.
Step 6: Deal With Swelling
Wood absorbs moisture and swells in humid weather, which is why many drawers stick only in summer. Run a dehumidifier or air conditioning and give the piece a few days. If a drawer still binds at one spot, lightly sand the high spot on the runner or drawer side, then wax it. Seal any bare wood you sand so it doesn't absorb more moisture. See our guide on protecting wood furniture from humidity.
Step 7: Lighten the Load
An overloaded drawer sags and scrapes. Store heavy items in lower drawers and stay within the drawer weight capacity listed for your furniture. The Nacre 6-Drawer Dresser, for example, lists a drawer weight capacity of 39 lbs, and its care instructions recommend checking drawer slides, handles and leg fittings periodically. See our guide on how to organize a dresser.
Step 8: Fix a Sagging Drawer Bottom
If the drawer bottom has slipped out of its groove or bowed, push it back into place and secure it with small screws, brads or glue blocks along the back edge. A thin support strip across the underside helps on wide drawers.
Step 9: Replace Worn Slides
Bent metal slides or broken rollers can't be fixed with lubricant. Measure the slide length and mounting type (side-mount, center-mount or undermount) and buy a matching pair. Replace both sides at once so they run evenly.
Quick Fixes by Drawer Type
| Drawer type | Most likely cause | First fix to try |
|---|---|---|
| Antique or wood-on-wood | Dry runners, swelling | Wax the runners |
| Ball-bearing slides | Dirt, misalignment, overloading | Clean, realign, lighten the load |
| Roller slides | Worn rollers, off the track | Re-seat the drawer; replace rollers or slides |
| Kitchen drawers | Grease and crumbs | Clean the tracks thoroughly |
| Dresser drawers | Overfilling, humidity | Remove items; lower humidity |
Drawer That Won't Close All the Way
Look behind the drawer first; something has often fallen into the back of the opening. Then check whether the slides are level, whether the stop at the back is loose, and whether the piece itself is level. A dresser that leans or sits on an uneven floor can twist the frame enough to bind drawers; adjust the leg levelers or shim the low corner. See our guide on how to fix a wobbly table for leveling tips.
Keeping Drawers Running Smoothly
- Don't overfill drawers or stack items above the drawer sides.
- Keep indoor humidity moderate, roughly 35 to 55 percent.
- Vacuum tracks when you clean the room.
- Re-wax wood runners once or twice a year.
- Check slide screws every few months, especially on drawers you use daily.
- Anchor tall dressers to the wall. See how to anchor furniture to a wall.

FAQ
What can I put on drawers to make them slide easier?
Paraffin wax, a plain candle or a dry bar of soap on wood runners; a light dry lubricant such as silicone spray on metal slides.
Why do my drawers stick in summer?
Wood absorbs moisture and swells when humidity is high. Lowering indoor humidity usually helps within a few days.
Can I use WD-40 on drawer slides?
It can clean metal slides, but oily products attract dust over time. A dry silicone or PTFE lubricant is usually a better choice, and you should avoid oils on wood runners.
How do I fix a drawer that drops when pulled out?
Tighten or realign the slides, repair stripped screw holes, and check that the drawer isn't overloaded. Replace slides that are bent or worn.
