Door Sticking or Not Closing Properly
A door that sticks or refuses to close properly is one of the most common household complaints — and in most cases it has a simple mechanical cause. Seasonal humidity causes wood doors to swell and tighten in summer. Loose or sagging hinges let the door drop, pulling the latch edge out of alignment. Paint buildup on door edges adds enough thickness to create a bind. Each of these problems has a different fix, and identifying the right one saves you from over-sanding or shimming when a simple screw tightening would do the job. This guide works through the diagnosis and repair in order from quickest to most involved.

Common Symptoms
- Door requires extra force or a shoulder push to close
- Door rubs or scrapes against the door frame on one side
- Door won't latch without lifting the door handle
- Door sticks in summer but works fine in winter
- Visible paint scraped off door edge or frame where they contact
Most Likely Causes
- 1
Seasonal Wood Swelling (Most Common in Summer)
Wood doors absorb atmospheric moisture in humid summer months and expand across the grain — primarily widening the door at the latch edge. A door that fits perfectly in January may gain 1/8 inch in width by July, enough to bind against the frame. This is normal behavior for solid-wood and hollow-core doors with wood stiles. Painting all six faces of the door (including top and bottom edges) dramatically reduces seasonal movement by sealing out moisture.
- 2
Loose or Sagging Hinges
Door hinges carry the full weight of the door and are stressed every time the door opens or closes. Over time, the hinge screws pull loose from the frame, letting the door sag and tip inward. The latch side drops, the door rubs at the latch-side bottom, and the hinge-side top gap widens. A telltale sign is a door that rubs on the bottom of the latch side with a widening gap at the top of the hinge side.
- 3
Paint Buildup on Door Edges
Multiple paint coats on the door edge and frame build up over years, gradually reducing the clearance gap until the door binds. This is especially common in older homes repainted many times. The paint layer is usually visible as a thick, uneven edge — sometimes you can see the paint cracking or flaking where the edge contacts the frame.
- 4
Foundation Settling / Racked Frame
House settling shifts the door frame out of square over years. If the rough opening racks into a parallelogram shape, the door — which is a rectangle — no longer fits the opening evenly. A racked frame produces a door gap that is wide at one corner and narrow at the diagonally opposite corner. Minor settling can be compensated with strike plate and hinge adjustments; significant racking requires a contractor.
- 5
Misaligned Strike Plate
If the latch bolt no longer aligns with the hole in the strike plate, the door will resist closing as the bolt catches on the strike plate face. This is often the result of hinge sag pulling the door down, moving the bolt below the strike plate hole. The fix may be as simple as filing the strike plate opening or moving the plate slightly.

Quick DIY Checks
Wear safety glasses when using a belt sander or hand plane on door edges — wood chips and paint dust can fly at eye level. Wear an N95 mask when sanding painted surfaces on doors painted before 1978 — they may contain lead paint. Use a lead test kit before sanding old paint.
- 1Step 1 — Identify the bind point: rub chalk, a crayon, or lipstick along all four edges of the door. Close the door firmly, then open it. The chalk transfers to the frame wherever the door is making contact — the smear marks tell you exactly where to focus your repair.
- 2Step 2 — Check and tighten hinges: open the door and tighten every hinge screw with a screwdriver. If a screw turns freely without tightening (stripped hole), remove it, pack the hole with wooden toothpicks and wood glue, let dry for 1 hour, then re-drive the original screw. This costs almost nothing and resolves 40% of sticking doors.
- 3Step 3 — Upgrade to 3-inch hinge screws if hinges are sagging: if the door sags (latch side drops, hinge-side gap is wide at top), replace the factory 3/4-inch screws in the door FRAME hinge leaf with 3-inch deck screws of matching diameter. These reach through the jamb and anchor into the structural framing, re-suspending the door. Start with the top hinge — that single change often resolves the sag.

Repair vs Replace
Door sticking problems are almost always repairable without door replacement. Hinge screw upgrades and shimming are free or under $5. Planing and sealing a swelling door costs under $30. Replace the door only if it is severely warped beyond correction (more than 1/4-inch bow across the face), has significant rot, or if the frame itself requires major structural correction.
Est. Repair Cost
$5–$80 (screws, shims, wood filler, hand plane, belt sander rental)
Est. Replacement Cost
$400–$1,500+ for a new pre-hung door with installation

Frequently Asked Questions
- My door sticks only in summer — will it fix itself in winter?
- Yes, usually — but it will swell again next summer unless you address the root cause. The permanent fix is to sand or plane the binding edge in dry weather (when the door is at its narrowest, typically January–February) and immediately seal all six door faces with paint or primer. Sealing the top and bottom edges, which are commonly left bare, is the single most effective prevention. Applying paste wax to the door edges each fall also helps slow moisture absorption.
- The hinge screws are stripped — how do I fix them without replacing the hinge?
- Remove the screw, pack the stripped hole with 3–4 wooden toothpicks and a few drops of wood glue. Let it dry for at least 1 hour (2 hours is better). Snap or sand the toothpicks flush with the surface, then re-drive the original screw. The toothpicks give the screw threads solid wood to bite into. This repair is stronger than the original and costs almost nothing. For a faster but less durable fix, drill the hole to 5/16 inch and tap in a wood golf tee, then re-drive the screw.
- Should I plane or sand the door edge?
- Use a hand plane for precise, controlled removal of thin layers — it's the right tool when the door needs only 1/16 to 1/8 inch removed. Use a belt sander when you need to remove 1/4 inch or more, or when the edge has a complex paint buildup. Both work; the plane requires more skill but gives more control. Always remove the door from its hinges before planing for safety and accuracy. Work in small passes, re-hang and test frequently — it's much easier to remove a little more than to put wood back.
- The door gap is uneven (one corner tight, opposite corner wide) — is the frame racked?
- Possibly yes, but start with the hinge diagnostics first. Sagging hinges produce an uneven gap that looks just like a racked frame: the top hinge-side gap widens and the bottom latch-side gap tightens. Tighten the hinges and upgrade to 3-inch screws — if the gap becomes even, the frame was fine and the hinges were the culprit. If the gap remains lopsided even with fully secured hinges, the frame has settled out of square. A contractor can re-square the frame by removing the door casing and adding shims behind the jamb.
- Can I use WD-40 to help a sticking door?
- WD-40 on the door edges or frame provides only temporary slipping relief — it doesn't address the cause and will wash away quickly. For hinge squeaking, WD-40 helps in the short term but use white lithium grease or petroleum jelly on the hinge pin for a lasting fix (see the Squeaky Door Hinge article). For a sticking latch mechanism, dry graphite powder sprayed into the latch bolt slot is the correct lubricant — it won't attract dust or gum up over time.
