A door that sticks or will not latch: what it is telling you about the house

Usually a small fix, occasionally a signal

Most doors that stick, rub or refuse to latch have a simple cause: loose hinge screws, wood that has swelled with humidity, a strike plate that no longer lines up with the latch, or layers of paint on the edges. Those are repairs measured in minutes or an hour, not days. The time to pay closer attention is when several doors start misbehaving at once, especially alongside new cracks in drywall or brick, because that pattern can mean the house itself is moving.

We repair and replace interior and exterior doors all the time at The DFW Handyman, and the sticking door is one of the most common items on the lists our clients send us. It is also one of the most misdiagnosed. People plane a door that only needed a longer screw, or ignore a door that was trying to tell them something about the slab. This guide walks through how to read the door, what you can fix yourself and when to bring someone in.

Read the gaps before you touch a tool

Close the door slowly and look at the space between the door and the frame. On a door that hangs properly, that gap is roughly even along the top and both sides. Where the gap is tight or disappears, the door is rubbing. Where it is wide, something has shifted away. The shape of the gap tells you most of the story.

Look for shiny or scuffed spots on the paint along the edge of the door or the frame; those are the rub points. Then open the door halfway and lift gently on the handle. If the door moves up and down and you can see the hinges flex, the hinges are loose. If the door is solid but still rubs at the top corner on the latch side, the frame or the door has shifted out of square.

• Tight at the top corner on the latch side: usually a loose top hinge letting the door sag
• Tight along the whole latch edge: often swelling from humidity or built-up paint
• Latch hits above or below the strike hole: the door has dropped or the frame has moved
• Daylight at the top of an exterior door but tight at the bottom: the frame may be racked
• Rubbing only in summer: seasonal swelling, not a structural problem

The usual suspects, from simplest to most serious

In our experience the causes fall into a predictable order. Start at the top of this list and work down; most doors are fixed before you reach the middle.

The further down the list you go, the more the repair involves the frame or the structure rather than the door itself, and the more it pays to have an experienced eye look at it before you start removing wood.

• Loose hinge screws, especially at the top hinge, which carries most of the door's weight
• Worn or bent hinges on a heavy or frequently used door
• Paint buildup on the door edge or the stop after years of repainting
• Swelling from humidity, often worse on bathroom and exterior doors
• A strike plate that has drifted out of line with the latch
• Weatherstripping on an exterior door that is too thick or has come loose
• A frame that has shifted, racked or begun to rot at the bottom of the jamb
• Movement in the foundation pulling door openings out of square

Why doors in North Texas houses have a hard life

Our weather is hard on doors. Long, humid summers swell wood, and drier stretches shrink it again, so a door that fits perfectly in January can drag across the threshold in August. Exterior doors take direct sun and rain on one face and air conditioning on the other, which encourages warping and loosens joints over time.

The soil adds its own pressure. In a report by Fox 7 Austin, a Texas A&M AgriLife soil scientist explained that many Texas soils swell when they get wet and shrink when they dry. That movement can shift a slab, and the same report lists a front or back door that sticks among the signs homeowners should watch for, along with cracks in interior and exterior walls. Across Dallas and its suburbs, that is why a sudden change in several doors deserves a closer look rather than a quick sanding.

Repairs worth trying yourself this weekend

If the gap test points to loose hinges, start there. Open the door and tighten every hinge screw on both the door and the frame. If a screw spins without biting, the hole is stripped. A common fix is to replace one of the screws in the top hinge with a longer one that reaches through the jamb into the framing behind it, which pulls the door back up and toward the hinge side. Use a screw with a head that matches the others so it sits flush.

If the latch is missing the strike, look at where it hits. A small misalignment can sometimes be fixed by filing the opening in the strike plate slightly larger. For a door that only sticks in humid months, try waiting a few weeks before taking wood off; it may free itself when the weather turns. Clean and lightly lubricate a sluggish latch, and check that exterior weatherstripping is seated properly and not bunched up.

Stop if the fix is not working after these steps, if you find soft or dark wood at the bottom of the frame, or if you are tempted to start sawing or planing. Those are the points where a small job can become a door replacement.

Signs the door is pointing at something bigger

A single sticky door is usually just a door. Several doors changing in the same season, especially on one side of the house, is a different conversation. So are diagonal cracks running up from the corners of door frames, gaps opening between trim and walls, cracks in brick that step up like a staircase, and windows that suddenly bind.

When we see that pattern, we do not just shave the doors to fit, because the doors would only shift again. We tell the homeowner to have the foundation evaluated first. A foundation specialist can explain what the cracks and gaps mean, and a foundation contractor has written a clear guide to stair-step brick cracks and sticking doors that is worth reading before you call anyone. Once the structure is stable, we come back and make the doors work again.

Why planing is the last resort, not the first

Planing or sanding the edge of a door feels like the obvious fix, and sometimes it is the right one. But it removes wood permanently. A door planed to fit during a humid August can rattle and leave gaps by winter. A door planed because the top hinge was loose will still sag, and the gap on the hinge side will now be too wide.

When planing is truly needed, the freshly cut edge has to be sealed or painted afterward. Bare wood absorbs moisture far faster than painted wood, so an unsealed edge can swell again and undo the repair. On exterior doors, planing the bottom without resealing it invites water damage. We plane only after the hinges, frame and strike are right and the door still binds.

The same caution applies to the frame. Hammering a door stop over or chiseling the jamb to make room can work in the short term, but it hides the reason the door moved. Fix the cause, then adjust the fit.

How we make a stubborn door close properly

We start by finding the cause, not the symptom. We check the hinges, the frame, the strike, the weatherstripping and the condition of the wood at the bottom of the jamb, and we look at the other doors in the house for a pattern. Then we give you a flat-rate price, with no fees or surcharges, for the repair that fixes the cause.

Many repairs are straightforward: re-securing hinges into solid framing, replacing worn hinges, shimming a hinge to correct the swing, resetting a strike plate or replacing weatherstripping. When the frame has rotted at the bottom or the door itself is warped or damaged, door replacement is part of our carpentry work, interior and exterior, including fitting the new door so it swings and latches cleanly. Every job carries a one-year warranty, and we are fully insured and bonded.

If a door problem turns out to be a symptom of something outside our work, such as foundation movement, we say so before we touch it, so you do not pay for a repair that will not last. And if you have other small items waiting, such as a loose handrail or a gate that drags, we can price them together and handle them in the same scheduled visit.

Keeping every door in the house working

A quick check of your doors twice a year, at the start of summer and again in late fall, catches most problems while they are still a screwdriver job. Tighten hinge screws, look at the paint on the edges, check exterior weatherstripping and thresholds, and note any door that has changed. Our guide to seasonal home maintenance in North Texas puts that check into a full calendar for the house.

If you would rather not keep track, our Annual Home Maintenance Plan puts these small checks on a schedule so they get done before something fails. Call, text or send the contact form with the doors that are giving you trouble and a photo of the gaps if you can. We are not an emergency service, so we schedule the visit and let you know exactly what we will do and what it will cost.
