Why Your Door Won't Close Properly: 7 Common Causes & DMV Fixes

A door that won't close properly is one of the most common service calls we get across Rockville, Silver Spring, Bethesda, and the rest of the DMV. It's also one of the most misdiagnosed — most homeowners assume the door itself is the problem, when in fact the door is fine and something around it has shifted, swollen, worn, or rotted.

Below are the seven causes we encounter most often, ordered roughly from most to least common. For each one, we describe what it looks like, why it happens, what fixes it, and whether it's something a confident homeowner can handle or a job worth calling a pro for.

1. Loose Hinge Screws (The #1 Culprit)

Easily the most common cause. The top hinge takes the most stress on any swinging door, and its screws gradually back out over years of use. Once even one screw loosens, the door starts to sag, and the latch no longer lines up with the strike plate.

How to spot it: The door scrapes the threshold at the latch corner, or you have to lift the door handle slightly to get it to latch.

The fix: Tighten the screws. If they spin in the hole, replace them with longer 3-inch screws that reach into the wall framing behind the jamb — that's also a free security upgrade. Our door hardware installation service includes this on every call.

2. Humidity Swelling (Especially in DMV Summers)

Maryland summers are humid enough that solid wood doors absorb moisture and physically grow by 1/8" to 1/4" at the edges. The door stops fitting its opening — usually sticking at the top corner or along the latch edge.

How to spot it: The door closed fine in winter and starts dragging in June or July. It frees up again in October.

The fix: If the sticking is seasonal, often the best move is to wait it out and then properly seal the door's edges with primer in the dry months to slow moisture absorption. If it sticks year-round, the door needs to be planed down at the dragging edge — a 30-minute job for a handyman with a power planer. Doing it yourself with a hand plane is doable but easy to overdo.

3. Foundation or Frame Settlement

Older Rockville and Silver Spring homes — particularly the 1950s and 1960s ramblers and split-levels — settle over decades. The frame goes slightly out of square, and a door that hung perfectly for 30 years suddenly won't close.

You can confirm settlement quickly with a 4-foot level. Hold it against the door jamb in both directions. If the jamb is more than 1/8" out of plumb top-to-bottom, settlement is contributing to the problem.

The fix: Minor settlement is usually solved by moving the strike plate up or down (or enlarging the strike opening with a file). Severe settlement may require shimming the hinges, planing the door, or in rare cases, rebuilding the rough opening. See our door replacement service for cases where the frame itself has to come out.

4. Worn or Misaligned Strike Plate

The strike plate is the metal piece on the door frame that catches the latch bolt. Over years of use, the latch wears a small groove and the plate itself can shift slightly as its screws loosen — both of which prevent the latch from seating properly.

How to spot it: The door closes but won't stay closed unless you pull the handle. Or it latches only when slammed hard.

The fix: Inspect the strike plate. If the latch is hitting the edge of the strike opening, the plate needs to move 1/16"–1/8" in the direction of the misalignment. You can either enlarge the existing hole with a metal file or unscrew the plate and reposition it. While you're there, swap to a security strike plate with 3-inch screws — both fixes happen in the same 10 minutes.

5. Failed or Compressed Weatherstripping

Weatherstripping doesn't just seal — it also creates the compression that holds the door tight against the jamb when latched. If the seal hardens and stops compressing, the door rattles. If it swells or comes loose, the door may not close all the way.

How to spot it: The door closes with extra resistance and won't sit flush against the frame. Or you feel a draft despite the seal looking "there."

The fix: Replace the weatherstripping with a properly sized seal. Our weatherstripping replacement service handles measurement, removal, and installation for all major door types. If you also notice gaps at the bottom of the door, the threshold or door sweep is the next thing to check.

6. Hinge Pin Wear or Bent Hinges

This is rarer but it happens — especially on heavy entry doors and on commercial-style hinges over 20+ years old. The hinge knuckle wears or the pin develops play, and the door drops just enough to stop closing properly.

How to spot it: The door shows a visible gap at the top hinge that wasn't there before, or you can lift the door slightly by its handle.

The fix: Replace the hinges. On a standard residential door, this is a 30–45 minute job with a chisel and screwdriver. For heavy mahogany or fiberglass entry doors with non-standard hinges, sourcing the replacement matters as much as the install — see our hardware installation service for help.

7. Door Frame Rot (The Most Expensive Cause)

This is the one we hope it isn't, but it's also the one homeowners ignore the longest. When water gets behind failing caulk or a damaged threshold, the bottom of the jamb rots from the inside. Once the wood softens, the hinge screws lose their grip and the door starts to sag — often with no visible exterior damage at first.

How to spot it: Press a screwdriver into the bottom 12" of the jamb (both sides). If it sinks in even slightly, rot is present.

The fix: If the rot is isolated to the bottom 6"–12", a jamb repair or partial replacement may be possible. Beyond that, the frame itself needs to come out — see our door replacement service. Either way, the underlying cause (failed caulk, bad threshold, missing drip cap) has to be fixed at the same time, or the rot returns within a year. Our recaulking service and threshold replacement address those upstream issues.

When to Call a Pro vs. Fix It Yourself

Tightening hinge screws, repositioning a strike plate, and swapping weatherstripping are well within reach for most homeowners. Planing a swollen door, replacing hinges on a heavy entry door, or addressing frame rot are jobs where doing it wrong is more expensive than calling someone. Frame rot in particular has a way of looking finished after a DIY repair, then re-emerging the following winter — at which point the original repair has to come out so the underlying cause can finally be addressed.

For Rockville, Silver Spring, Potomac, and the rest of the DMV, NextDayJose handles all seven of these problems on a same-day basis. Most door-closing issues are resolved in a single visit, and we'll tell you upfront if what you're describing actually needs a door replacement rather than a repair.
