Quick Answer
A sticking door is usually caused by one of three things: swollen timber from humidity, loose or worn hinges, or building movement causing the frame to shift. Most sticking door fixes are DIY-friendly and cost under $30 in materials — a plane, some sandpaper or new hinge screws. The exception is structural movement (cracks around the frame), which needs a builder to assess.
Sticking doors are one of the most common problems in Melbourne homes. Humidity in summer swells timber frames; Melbourne clay soil shifts during wet winters and dry summers, moving door frames slightly out of square; and ageing homes simply settle over time. Here’s how to diagnose exactly what’s causing your door to stick and fix it for good.
Step 1: Identify Where the Door is Sticking
Close the door slowly, watching closely for where it first makes contact. Mark the binding point with a pencil while the door is in contact with the frame. This tells you which of the three main causes you’re dealing with:
| Where It Sticks | Most Likely Cause | Solution |
|---|---|---|
| Top latch corner drags on frame | Loose top hinge (most common) | Tighten or replace hinge screws |
| Bottom hinge side drags | Bottom hinge loose or frame shifted | Tighten bottom hinge; plane if needed |
| All along one edge in summer | Timber swollen from humidity | Plane lightly; seal cut edge |
| Whole door sits too low | Hinge mortises worn; hinges sagging | Pack hinge mortises; replace hinges |
| Latch won’t engage (off-centre) | Frame movement / settling | Adjust strike plate position or plane |
| Sticking with cracks around frame | Structural movement or subsidence | Consult a builder before touching the door |
Step 2: Fix Loose Hinges First (Try This Before Planing)
Roughly 60% of sticking door problems in Australian homes are caused by loose hinges — specifically the top hinge. The screw holes strip over time, the hinge works loose, and the door hangs low on the latch side, causing it to drag on the top of the frame opposite the hinge.
To fix stripped screw holes: remove the hinge, inject a small amount of PVA glue into the hole and tap in wooden toothpicks or matchsticks until the hole is filled. Once dry, trim flush with a knife and re-drive the original hinge screws. For severely stripped holes, use longer 50mm or 65mm screws that reach into the structural stud behind the door lining — this is often the most permanent fix.
Step 3: Plane the High Spot
If tightening hinges doesn’t fix the sticking, the door needs to be planed. Mark the binding area clearly with a pencil or chalk. If the door sticks all along one edge, use a hand plane working along the grain. If it’s just a small corner or spot, a sanding block works well enough and avoids over-cutting.
Work in small passes, checking the fit regularly. It’s easy to remove too much — take off 0.5mm at a time and re-hang the door to check. When the door swings and closes freely with about 2–3mm clearance on all sides, you’re done.
Step 4: Seal the Planed Edge
Bare, freshly-planed timber absorbs moisture. In Melbourne’s humid summers and wet winters, an unsealed edge will swell again and you’ll be back where you started. Once the door closes cleanly, paint or seal the planed edge with undercoat and the same paint as the door face, or apply a coat of clear timber sealer if the door is stained or unpainted. This is the step most DIYers skip — and the reason the problem comes back.
Adjusting the Strike Plate
If the latch clicks but doesn’t hold, or the door rattles shut, the issue is strike plate alignment rather than a swollen door. Use a pencil or lipstick on the latch tongue, close the door and check where it’s hitting the strike plate. If the latch is hitting the edge of the plate opening rather than engaging cleanly, the strike plate can be shifted: unscrew it, use a chisel to enlarge the mortise by 2–3mm in the relevant direction, and re-fix.
When to Call a Builder
Sticking doors accompanied by visible cracks in plasterwork or brickwork around the door frame can indicate structural movement or subsidence. This is particularly common in south-east Melbourne suburbs like Dandenong, Cranbourne and Pakenham where reactive clay soil causes significant foundation movement between wet and dry seasons. Before planing a door or adjusting hinges, check the frame carefully. If you see diagonal cracks at the corners of the door opening, or the frame itself is visibly racked (one side higher than the other), consult a structural engineer or licensed builder before carrying out any works — planing a door in a settling frame can cause the problem to recur and masks the underlying movement.
What You’ll Need
| Tool / Material | Cost | Notes |
|---|---|---|
| Hand plane (No. 4 or block plane) | $30–$80 buy, or hire | Block plane for small spots; No. 4 for full edges |
| Sandpaper (80-grit and 120-grit) | $8–$15 | For small sticking spots |
| Longer hinge screws (50–65mm) | $5–$10 per pack | Brass or zinc; to re-engage into stud |
| PVA glue + matchsticks/toothpicks | $5–$10 | To plug stripped screw holes |
| Pencil or chalk | $2 | To mark sticking point |
| Paint or clear timber sealer | $10–$20 | To seal planed edge |
Top 10 Tips and Gotchas
- Try tightening the hinges before planing anything. Over 60% of sticking doors in older Melbourne homes are caused by loose hinges, not swollen timber. Fix the hinges first — it takes 10 minutes.
- Mark the exact binding point before removing the door. Once the door is off its hinges, it’s easy to lose track of exactly where it was sticking. Mark it clearly while it’s in the frame.
- Work in small increments when planing. Remove 0.5mm at a time and re-hang the door to check. Taking off too much leaves a visible gap and means painting the frame or the door edge to compensate.
- Always seal planed edges. Bare timber will re-swell in Melbourne’s humidity within one season. One coat of sealer or paint on the planed edge prevents the problem coming back.
- The door swelling in summer and clearing in winter is normal. If the door sticks in summer but swings freely in winter, the timber is responding to humidity. Plane just enough to clear in summer — not so much it rattles in winter.
- Check the door frame is square. Hang a plumb bob at the top and check the frame is vertical. Out-of-square frames mean the door will bind somewhere no matter how much you plane. Shimming hinges can compensate for minor frame issues.
- Use a wax candle on the hinge pivot. A candle rubbed on the hinge pivot reduces friction and stops squeaking without leaving marks. WD-40 also works but attracts dust long-term — silicone lubricant is better for ongoing lubrication.
- Replace the full hinge if it’s damaged. Bent or corroded hinges are worth replacing entirely ($8–$20 each from Bunnings). Match the size (height × width × thickness) exactly when buying replacements.
- Door won’t latch? Check the strike plate first. Before assuming the door needs planing, put lipstick on the latch, close the door, and check where it hits the strike plate. Often just filing or shifting the strike plate 2–3mm is all that’s needed.
- Watch for signs of structural movement in SE Melbourne suburbs. In areas like Cranbourne, Pakenham and Berwick built on reactive clay soil, multiple doors sticking at once — especially after a dry summer or wet winter — can be an early warning sign of foundation movement that needs engineering assessment.

Frequently Asked Questions
Why does my door stick in summer but not winter?
Timber absorbs moisture from humid summer air and expands — this is completely normal. Melbourne’s summer humidity causes this in most homes with timber doors and frames. Plane the door just enough to clear in summer conditions; a door planed too much for summer comfort will rattle in the frame during a dry winter.
How much does it cost to fix a sticking door in Melbourne?
If you’re DIY-ing it, fixing a sticking door typically costs $10–$30 in materials — longer screws, sandpaper, and paint to seal the edge. If you hire a carpenter, expect to pay $80–$200 depending on the extent of planing required and call-out fees. Most experienced carpenters in Melbourne complete a sticking door fix in under an hour.
Can I fix a sticking door without removing it?
Yes, for small sticking spots at the edge or top corner. Use a sanding block or a Surform rasp on the binding area with the door in place — open the door to 90 degrees, hold it steady, and sand the edge that’s catching. For more serious planing, it’s easier to remove the door from its hinges and work on it flat across two sawhorses.
When is a sticking door a sign of something serious?
A single door sticking after a wet summer is normal. Multiple doors sticking simultaneously, doors that were fine before then suddenly stuck, or sticking accompanied by new cracks in walls or ceilings can indicate foundation movement or structural issues. In Melbourne’s reactive clay soil areas — particularly Cranbourne, Pakenham, Berwick and Dandenong — this deserves investigation by a licensed builder or structural engineer.
Final Thoughts
Most sticking doors in Melbourne homes are a 30-minute fix — tighten the hinges, seal the planed edge, done. The key is diagnosing the cause before picking up the plane. Check hinges first, mark the sticking point precisely, and keep an eye out for the structural movement warning signs that are common in SE Melbourne clay-soil suburbs.
- Check and tighten hinges before planing anything — it fixes most cases
- Seal planed edges with paint or sealer to prevent re-swelling
- Multiple sticking doors + wall cracks = get a builder to look before DIY-ing
- Allow 2–3mm clearance all round for Melbourne’s humidity range
