A door that closed easily in the spring can suddenly need a shoulder check by summer. If that sounds familiar, the door probably hasn't changed — the air around it has. Central Florida's humidity swings are hard on wood doors and windows, and the fix depends on catching the right cause rather than just forcing the latch harder. Here's what's actually going on and how to handle it.
Why Humidity Makes Wood Swell
Wood is porous, and it absorbs moisture straight out of the air. In Central Florida, indoor humidity can swing noticeably between the drier winter months and the long, wet stretch from late spring through early fall. A solid-wood door or window sash soaks up that extra moisture and expands slightly — often just a sixteenth of an inch, which is more than enough to turn a door that closed smoothly into one that catches on the frame or a window that won't slide past a certain point. Hollow-core doors and vinyl windows move less, but the wood jambs and trim around them still swell and shift the opening itself.
The Four Most Common Causes
Wood Expansion in the Door or Sash Itself
This is the classic humidity sticker: the door drags along the top corner opposite the hinges, or a window sash binds partway through its track. It tends to show up gradually across a few weeks as humidity builds, rather than overnight.
Frame and Jamb Movement
The frame around a door or window is made of wood too, and it absorbs moisture on its own schedule. A frame that's swollen or slightly twisted changes the shape of the opening, which is why a door can bind at the top in one season and at the bottom in another.
Worn or Compressed Weatherstripping
Weatherstripping that's cracked, flattened, or peeling changes how a door sits in its frame, sometimes making it feel tight even when the wood itself hasn't moved much. Replacing it is one of the cheapest fixes on this list and it also keeps humid air and wind-driven rain from working their way inside — the same seal problem covered in our hurricane season checklist.
Hinge, Strike Plate, and Track Wear
A door that drops slightly on worn hinges, or a strike plate that's no longer lined up with the latch, can look like a humidity problem when it's really a hardware problem. The same goes for window tracks that have collected enough dirt or corrosion to bind the sash. Worth ruling out before assuming it's the wood.
Wet Season vs. Dry Season: What to Expect
Doors and windows in Central Florida homes tend to bind the most from roughly May through September, when humidity runs highest and afternoon storms keep the air damp even indoors. Come the drier winter months, a lot of that swelling eases off — which is exactly why a quick fall fix can feel unnecessary and then turn into a frustrating surprise the following summer. If a door is sticking badly enough now that you're forcing it, it's a safe bet it will do the same thing again next wet season unless something's actually adjusted.
What You Can Try Yourself
Start by figuring out exactly where it's binding — close the door or window slowly and watch for the contact point, or look for shiny, worn spots on the edge where paint has rubbed off. A light pass with fine sandpaper on an obvious high spot can buy some room. Tightening loose hinge screws, swapping a stripped screw for a slightly longer one, and cleaning out a dirty window track are all quick, low-risk fixes that solve a surprising number of cases. Lubricating hinges and locksets with a dry lubricant also helps hardware keep working smoothly through humidity swings instead of binding up or corroding.
When It's Worth Calling a Handyman
If a door needs to be planed to fit properly, a frame has shifted enough that the latch no longer lines up with the strike plate, or a window won't stay open without being propped, that's past the point of a quick sand-and-tighten fix. Planing a door unevenly is one of the more common DIY mistakes we get called to fix — it solves the sticking but leaves a gap once the wood shrinks back down in the dry season. Our door and window service covers planing and rehanging doors, replacing worn weatherstripping and hardware, and freeing up stuck window tracks and screens so they hold up through the next humid stretch, not just this one.
Sticking doors and windows are also one of the early warning signs covered in our guide to preventing humidity damage, alongside musty odors and soft drywall — worth a read if you've noticed more than one of these at once. And if you've just closed on a home and aren't sure what else to check first, our new homeowner 90-day checklist covers doors, plumbing, and electrical items worth a look early on.
We handle door and window repairs for homeowners throughout Central Florida. If something's sticking, dragging, or won't latch right, reach out for a free estimate and we'll get it adjusted properly the first time.

Frequently Asked Questions
Will a sticking door fix itself once the weather dries out?
Sometimes it loosens up a little in the drier months, but the wood has already swelled and compressed once it's been stuck. Most doors keep getting a little worse each humid season rather than fully resetting, so a door that's noticeably sticking is worth planing or adjusting rather than waiting out.
Is a sticking door ever a sign of a bigger problem?
Usually not — most sticking in Central Florida is simple humidity swelling or worn weatherstripping. But if a door or window has started sticking suddenly along with new cracks in nearby drywall, or several doors in the same part of the house are sticking at once, it's worth having someone take a look, since that pattern can point to settling rather than just moisture.
Can I just plane down a sticking door myself?
You can, but it's easy to take off too much or plane an uneven edge, which leaves a visible gap once the wood shrinks back down in a drier month. A light sanding on an obvious high spot is a reasonable DIY fix; anything beyond that holds up better when it's planed, squared, and refinished properly.
Do you fix windows too, or just doors?
Both. We handle sticking and misaligned interior and exterior doors, window tracks and screens that have swollen or warped, and the weatherstripping and hardware on each. If a window won't stay open or a screen has popped out of its track, that's a quick fix for us.
