Most old doors that won't close can be fixed right where they hang, without taking them off to restore or replacing them. The usual causes are loose or stripped hinge screws, a house that has shifted, or wood that swells with the seasons. The fixes are small, and they go in order: hinges first, then the stop, and shaving the door edge last.
Why we try to keep the original doors
I was in a 1950s house in Short Hills, part of Millburn Township, that still had its original doors. Beautiful ones. Several of them weren't closing the way they should, and the owner asked us a fair question: could the doors stay, or would they have to be replaced?
Our answer was simple. As long as we can make them work, we don't need to change anything.
That's how we feel about most old houses. Someone made those doors and hung them by hand, and they've been opening and closing for about seventy years. A new door rarely matches the weight, the panels or the way the old hinges sit in the frame. We'd rather respect the work that was done before us, fix what's there, and leave it a little better than we found it. Plenty of older houses in Summit, Chatham and the rest of Millburn have the same kind of doors, and the same problems.
Adjusting a door or two fits inside a regular home maintenance visit. A whole house of original doors is something we'd scope as a home repair project.
Why do old doors stop closing?
Old doors stop closing because the house around them moves. Wood swells in a humid New Jersey summer and shrinks when the heat runs in winter, so a door that closes easily in January can rub in August. Houses also settle over the decades, and door frames go slightly out of square with them.
Renovations are the other big cause. When walls are moved or reframed, or a floor is leveled, the door frames nearby can shift a fraction of an inch. That's all it takes. A door that worked fine before a renovation can start sticking afterward, once the house settles around the new work.
And sometimes it's simpler than that. Hinge screws work loose or strip their holes, and the door drops toward the latch side.
How can you tell what's making a door stick?
You can usually tell what's wrong with a sticking door in five minutes, just by looking. Do this before you touch a tool.
- Check the gap around the closed door. It should be an even, narrow line along the top and the latch side. If it's tight near the top of the latch side and wider along the top near the hinges, the door has dropped.
- Find where it rubs. Look for shiny, worn paint or bare wood on the door edge or the frame. Or close the door on a sheet of paper at different points and feel where it grips.
- Lift the handle. Open the door and lift gently on the knob. If the hinges shift or click, the screws are loose.
- Start with the top hinge. It carries most of the door's weight, so it usually loosens first.
- Look at the wall around the frame. New diagonal cracks running up from the top corners of the door opening mean the house has moved, not just the door.
How do you fix stripped hinge screw holes?
Stripped hinge screw holes are fixed by packing them with wood and glue, then driving the screw back into fresh material. It's an old fix and a good one. It holds far better than forcing a fatter screw into a worn hole.
- Slide a wedge or a few shims under the door so its weight comes off the hinges.
- Take out one screw at a time from the loose hinge, so the door stays in place.
- Coat a few thin wooden sticks (toothpicks or a small dowel) with wood glue and tap them into the hole until it's packed tight.
- Let the glue dry. Then trim the sticks flush with a sharp chisel or utility knife.
- Drill a small pilot hole and drive the screw back in.
On a solid wood door, a slightly longer screw on the door side bites into fresh wood and holds well. Hollow-core doors only have a strip of solid wood along the edge, so a longer screw there doesn't help. On the frame side, a 3-inch screw in the top hinge can reach the wall framing behind the jamb and pull a dropped door back into line. Old hinges often have slotted brass screws, so match the head and finish and it won't look like a repair.
When should you move the door stop or a hinge?
Move the door stop when the door hits it before the latch can catch, or when the door closes but rattles. The stop is the thin strip of wood around the inside of the frame that the door closes against. If the house has shifted, the stop may no longer be where the door needs it. Run a utility knife along the paint line first so the paint doesn't tear, ease the stop off, move it slightly, and nail it back.
A hinge can be moved too. A thin piece of cardboard behind one hinge leaf changes the angle the door hangs at. Making a hinge recess a little deeper does the opposite. These moves are often no thicker than a business card, and they're usually enough to bring the latch back in line without touching the door edge at all.
When should you sand or plane a sticking door?
Sanding or planing a door is the last step, not the first. Once wood comes off it doesn't go back on, and a door trimmed to close in a humid August can show a gap you see light through in February.
- Mark the exact spot that rubs and take off only that.
- In summer, take off less than you think you need. The wood will shrink once the heat comes on.
- Shave rather than sand where you can. A hand plane takes the wood off in curls. Sanding makes fine dust that settles all over the room.
- Seal the bare wood afterward with paint or a clear finish to match. An unsealed edge soaks up moisture and swells again.
If the house was built before 1978, have painted doors tested for lead before anyone sands, planes or scrapes them. The EPA says homes built before 1978 are more likely to have lead-based paint, and that sanding it can create hazardous dust. A 1950s house sits right in that range, and a door may carry many layers of old paint under the newest coat.
Why is old interlocking weatherstripping worth keeping?
Many older doors have metal weatherstripping that interlocks. A shaped strip on the door fits into a matching channel on the frame when the door closes. When it's straight and lined up, it seals well and lasts for decades. It's a clever system, and we keep it whenever we can.
The trouble starts when the metal gets bent. A bent strip catches instead of sliding into its channel, and suddenly the door won't close, or only closes with a shove. Sometimes the strip can be eased back into shape. Sometimes a section has to be replaced. Either way, check the weatherstripping before anyone planes the door, because the door may not be the problem at all.
What are the options for new weatherstripping on an old door?
New weatherstripping matters most on doors that lead outside or to a space you don't heat: a sunporch, an attic, a basement, the garage. When the old system can't be saved, there are two good approaches.
- A new door bottom. Some door bottoms fit around the bottom edge of the door. To fit one, the door is trimmed slightly at the bottom so the new piece attaches and still clears the floor.
- Wider stops with a built-in seal. Swapping the existing stop for a wider one with a soft seal along its edge closes the gap at the sides and top. The door presses into the seal as it shuts.
Whichever you choose, the goal is to stop the draft. Hold the back of your hand along the edges of the closed door on a windy day. If you feel air moving, it's worth fixing before winter. Our guide to winterizing your house covers the rest of the house.
Should you repair or replace an old door?
Repair an old door if the wood is sound. A solid door with a loose hinge, a bent weatherstrip or a swollen edge is usually a small job, and it keeps something you can't buy new. Replacement makes sense when the door is split through, rotted or badly warped. Even when the frame has moved a lot, it's worth asking whether the original door can be rehung in a corrected frame before giving up on it.
Small problems with doors also tend to grow. A sagging door slowly wears its own hinges and the frame. That's one reason we think small house problems are cheaper to fix early.
When to call a professional
- Anything involving the lock or deadbolt. We hold keys for our clients, so we don't work on locks. A locksmith is the right call.
- Lead paint. If a test shows lead and the door needs sanding, planing or trimming, hire a firm that is EPA lead-safe certified.
- Signs the house is moving. New diagonal cracks above doors, several doors sticking at once, or floors that suddenly slope. A contractor or structural engineer should look before anyone adjusts the doors.
- Doors that need full restoration. Stripping old finish, repairing split panels or regluing loose joints is work for a door restorer or a skilled woodworker.
- Exterior doors with soft or dark wood near the bottom. That's often water damage, and the frame may need more than a new seal.
Frequently asked questions
Why does my door stick in summer but close fine in winter?
Wood takes on moisture from humid summer air and swells, then dries out and shrinks when the heat runs. A door that fits well in winter can rub in August. If it only sticks for a few weeks a year, adjust the hinges or take off very little.
Can you fix a stripped hinge screw hole with toothpicks?
Yes. Wooden toothpicks or a small dowel coated in wood glue, packed into the hole, left to dry and trimmed flush give the screw fresh wood to grip. Let the glue dry fully before you drive the screw back in.
Should you paint the edge of a door after planing it?
Yes. Bare wood absorbs moisture faster than sealed wood, so an unsealed edge will swell and can stick again. Paint or a clear finish that matches the door seals it. Include the top and bottom edges if they were trimmed.
Do old doors have lead paint?
They might. Homes built before 1978 are more likely to have lead-based paint, and doors often carry many layers of it. Have painted doors in an older house tested before anyone sands, planes or scrapes them.
How big should the gap around an interior door be?
Roughly 1/8 inch along the top and the latch side. An even gap matters more than the exact size. A gap that's wide in one corner and tight in another tells you the door has dropped or the frame has moved.
