Door Won't Close Right? Fixing a Sticking Door in Humid Florida
If your interior door has started dragging on the carpet, or your front door needs a shoulder-check to latch, you're not imagining it. South Florida's humidity swings are hard on wood doors, and the fix is usually simpler than replacing the whole thing.
Key takeaways
- Miami humidity swells wood doors seasonally, most sticking is not a structural problem
- Tighten hinges and try the 3-inch screw trick before sanding or planing
- Plane in small passes with the grain, and always reseal exposed wood edges
- For exterior doors, adjust the threshold and check weatherstripping before altering the slab
- Warped doors or frame issues from settling are worth a professional assessment
Why Doors Stick So Much in Miami
Wood is hygroscopic, meaning it absorbs moisture from the air and expands. Miami's relative humidity often sits above 70-80% for months during the wet season (May through October), and even in the 'dry' season it rarely drops below 50%. Solid wood doors, and to a lesser extent wood-composite doors, swell along the grain, adding fractions of an inch to their width and thickness.
That doesn't sound like much, but door frames are cut with tight tolerances, usually 1/8 inch to 3/16 inch of clearance around the door slab. When a door swells even 1/16 inch on two edges, it's enough to bind against the frame, especially at the top corner near the strike plate or along the bottom where it rubs the threshold.
You'll often notice the problem gets worse right after a rainy stretch and eases up somewhat in cooler, drier months. That seasonal pattern is actually a good diagnostic clue that humidity, not a structural issue, is the cause.
- Peak sticking season: June through September
- Common trouble spots: top outer corner, bottom edge near hinges, and the latch side
- Hollow-core interior doors swell less than solid wood but their frames can still shift
Diagnose Before You Sand Anything
Before reaching for sandpaper, figure out exactly where the door is rubbing. Close the door slowly and watch where it makes contact, or slide a piece of paper around the perimeter while it's shut. Wherever the paper won't slide through freely, that's your friction point.
Also check whether the problem is the door swelling or the hinges sagging. Grab the door by the outer edge and lift gently. If you feel play or hear a slight clunk, loose hinge screws (not humidity) may be the real culprit, and that's a five-minute fix, not a sanding job.
- Rub marks or paint scuffing show the exact contact point
- A door that drags across the whole bottom often needs threshold or hinge adjustment, not planing
- A door that only sticks at the top latch corner is classic humidity swell
Quick Fixes That Don't Require Removing the Door
Many sticking doors can be fixed without pulling the slab off its hinges, especially early on before the swelling gets severe.
Start with the cheapest fix: tighten every hinge screw. Humidity also swells the wood around screw holes, letting hinges shift slightly. If screws spin without biting, remove them, dip a golf tee or wooden matchstick in wood glue, pack the hole, let it dry, and re-drive the screw.
If tightening doesn't solve it, try the '3 for 2' trick on the top hinge: replace the two center screws in the top hinge with 3-inch screws that reach into the framing stud behind the jamb, not just the jamb itself. This pulls the whole door assembly slightly back into square and can close small gaps without any sanding.
For a door that's just barely dragging, rubbing a bar of paraffin wax or a candle along the contact edge reduces friction temporarily. It's not a permanent fix but buys time until you can address the swelling directly.
- Tighten all hinge screws first, it's free and takes minutes
- Use 3-inch screws in the top hinge to snug the frame
- Wax or a dry bar soap on rub points reduces friction short-term
Planing and Sanding the Swollen Edge
When the door is genuinely swollen and rubbing along an edge, planing is the real fix. Mark the rub area with a pencil so you know exactly where to remove material, then take the door off its hinges (tap the hinge pins up and out with a screwdriver and hammer) and lay it flat across two sawhorses.
Use a hand plane for the latch or top edge, working in the direction of the wood grain to avoid tearing it. Remove thin passes, about 1/32 inch at a time, and rehang the door to test fit before removing more. It's much easier to take off a little more than to add material back.
For small amounts of swelling, a sanding block or belt sander with 100-120 grit paper works fine and is less intimidating than a hand plane for most homeowners. Always finish by sealing the freshly exposed wood, top, bottom, and the edge you worked on, with primer and paint or a coat of polyurethane. Unsealed edges are exactly where the next round of humidity swelling starts.
- Remove material in small passes, 1/32 inch at a time
- Plane with the grain, not against it
- Seal every edge afterward, bare wood absorbs moisture fastest
Weatherstripping and Threshold Adjustments for Exterior Doors
Exterior doors deal with more than humidity swell, they also face direct sun exposure, salt air near the coast, and wind-driven rain that can warp a slab over time. If your front or back door sticks only in certain weather, check the weatherstripping and threshold first.
Compressed or torn weatherstripping lets the door sit unevenly in the frame. Most adjustable thresholds have small screws that raise or lower the sill, a quarter turn at a time, to close gaps at the bottom without touching the door itself. This is often a better fix for exterior doors than sanding, since it preserves the door's factory seal against wind-driven rain, which matters during hurricane season.
- Check adjustable threshold screws before sanding an exterior door
- Replace brittle or compressed weatherstripping annually in coastal homes
- Preserving the door's seal matters for storm protection, not just comfort
When to Call a Pro
Most sticking-door problems are manageable DIY projects with basic tools. But there are situations where it's worth having someone experienced handle it: a door that's warped rather than swollen (visible bow or twist when sighted down the edge), a frame that's out of square from foundation settling, or an exterior door where planing risks breaking the weather seal on an insulated slab.
Gold Hands Miami handles door repair, adjustment, and replacement across South Florida, including hinge repair, planing, threshold adjustment, and weatherstripping. We're insured for residential work. If the issue turns out to involve structural framing or anything requiring permitted work, we'll always tell you and refer you to a licensed contractor rather than push a fix that isn't appropriate.

Frequently Asked Questions
Why does my door only stick in summer?
Wood absorbs ambient moisture, and South Florida humidity is highest from May through October. The door swells slightly during those months and often loosens back up in the drier winter months. If it's purely seasonal, planing may only be a partial fix since the door will shrink again later.
Can I just cut a lot off the door to fix it permanently?
No, removing too much material creates gaps when the door shrinks in drier months, and it can compromise weatherstripping fit on exterior doors. Remove only what's needed to relieve the current rub, and reseal the edge.
Is it the door or the frame that's the problem?
Both swell, but frames are usually anchored to wall studs and move less than the door slab itself. If the whole house seems to have doors sticking on one side, it can point to foundation settling rather than humidity, which is worth a professional look.
Will a dehumidifier stop my doors from sticking?
Running central AC or a dehumidifier to keep indoor relative humidity around 45-55% definitely reduces wood movement and can prevent minor sticking, but it won't fix a door that's already swollen and needs planing.
How much does it cost to fix a sticking door?
Simple hinge tightening or a threshold adjustment can take under 30 minutes. Planing and resealing a door typically takes a bit longer since it involves removing the door, test-fitting multiple times, and finishing the edge. Costs vary based on the door type and how much work is needed; Gold Hands can give a straightforward estimate after a quick look.
