Fixing Sticking Doors and Windows in Humid Florida Climates

A door that drags in August and swings perfectly in February is one of the most common complaints in Delray Beach homes, and it is also the one where the instinctive fix causes the most damage. Reaching for a plane makes the summer problem better and leaves you with a permanent gap for the rest of the year.

Diagnosing it properly first takes ten minutes and usually leads somewhere else entirely.

Work out where it is actually binding

Close the door slowly and watch. Slide a piece of paper around the perimeter and find where it will not pass. The location tells you the cause:

• Binding at the top of the latch side almost always means the top hinge has loosened and the door has dropped. This is the single most common cause and it has nothing to do with humidity.
• Binding at the bottom of the latch side suggests the bottom hinge, or a threshold adjusted too high.
• Rubbing along the whole latch edge points to a frame that has moved, or genuine swelling.
• Latch will not engage but the door closes is a strike plate alignment problem, not a door problem at all.

Start with the screws, seriously

Before anything else, tighten every hinge screw. Doors are heavy, they get pulled and pushed thousands of times, and hinge screws work loose. If a screw spins without biting, the hole has worn out; replacing that screw with a longer one that reaches the framing behind the jamb usually lifts the door back into position on its own.

This one step resolves a large proportion of sticking doors, costs nothing, and is completely reversible.

If it is genuinely seasonal

Wood does absorb moisture and expand, and in a Palm Beach County summer that is real. But before removing material, consider that the change is temporary and the removal is not. Better options in order: adjust the hinges, adjust the strike, and if a door truly must be relieved, take the smallest amount possible from the edge and then seal the bare wood.

Sealing matters and is nearly always skipped. An unsealed door edge, top and bottom, absorbs moisture freely. Sealing all six surfaces slows the seasonal movement considerably. The tops and bottoms of interior doors in particular are almost never finished, and that is where most of the moisture gets in.

Windows are a different problem

Sliding windows and sliders that have become hard to move are rarely swollen. Usually the track is full of grit, or the rollers have worn or seized. Cleaning the track thoroughly and replacing worn rollers restores most of them.

Use a dry lubricant rather than an oil-based spray. Oil attracts and holds dust, so an oiled track works beautifully for two weeks and then becomes worse than it was.

Single-hung windows that will not stay up have failed balances, which is a specific replacement part rather than an adjustment. If a slider has become genuinely heavy, it is worth having the rollers and track inspected before someone hurts a shoulder wrestling with it.
