Signs Your Door Hinges Need Replacing

Hinges carry the entire weight of a door every time it opens, so they wear before almost anything else. Catching a worn hinge early saves the frame and the latch from taking the strain.

The slab drags or sits low

A door that catches on the threshold or rubs the latch-side jamb is usually sagging, and the most common cause is hinge wear or loose hinge screws. The top hinge takes the most load, so it loosens first and the door tips. If the gap along the top of the door is wider on the latch side than the hinge side, the door has dropped. That is the classic sagging door pattern.

Squeaking that oil does not fix

A squeak is metal wearing on metal. Oil quiets it for a while, but if it keeps coming back the hinge pin and knuckle are worn loose and the play will only grow. Loose play at the hinge lets the door shift, which then throws off the latch alignment.

Visible wear, rust, or bent leaves

Look at the hinge with the door open. Knuckles that no longer line up, a pin that has worked partway out, rust on an exterior hinge, or a leaf bent from a past impact all mean the hinge is past its service life. On exterior doors, rust is common where Ottawa road salt and melt water reach the bottom hinge.

Hinge screws that will not stay tight

Before you blame the hinge itself, check the screws. The single most common cause of a sagging door is not a worn hinge at all — it is screws that have stripped out of the jamb and no longer grip. The short factory screws only bite into the thin jamb material, and once that wood gives up, the door drops. The fix is simple and cheap: replace the top-hinge screws with 3-inch screws long enough to reach the framing stud behind the jamb. That single change pulls many doors back into square without touching the hinge. If the screws keep loosening even after that, the holes are worn out and the hinge needs to be reset or moved slightly.

What climate does to exterior hinges

Ottawa is hard on exterior hinges, and the bottom one suffers most. Road salt, slush, and melt water splash up against the lower part of the door all winter, and that salty moisture corrodes a hinge far faster than dry weather would. Freeze-thaw also works moisture into any gap, so a hinge that looks fine in summer can show rust streaks and stiff movement by spring. If your bottom hinge is rusting, binding, or staining the jamb, that is a clear signal to replace rather than keep oiling it. Choosing a properly finished exterior-grade hinge the second time around buys far more life, and it ties into broader hinge and hardware repair.

One hinge or the whole set?

When one hinge is worn, the question is whether to replace just that one or the full set. The top hinge carries the most weight and usually fails first, so it can genuinely be the only culprit. But fitting a single new hinge alongside two old, worn ones can leave the door hanging unevenly, because the new knuckle sits tighter than the worn ones. On an exterior door that has weathered years of Ottawa winters, replacing all three together keeps the slab hanging true and saves a return trip. On a light interior door, a single matched hinge is usually fine.

How to test a hinge in two minutes

You do not need tools to tell whether a hinge is the problem. Open the door to about 45 degrees and gently lift up on the latch edge. If the door rises and you feel or hear play at the hinges, the pins and knuckles are worn. Next, look at the gap, called the reveal, between the slab and the frame along the top and the latch side. On a healthy door it is even, roughly the width of a nickel, all the way around; when a hinge has failed, that gap pinches closed on one side and opens up on another. Finally, watch the door swing slowly — a door that drops or drifts as it moves through its arc is telling you the hinges are no longer holding it square. These three checks separate a worn hinge from a problem somewhere else, like the latch alignment or the frame.

Interior vs. exterior hinges

Interior and exterior hinges age very differently, and that changes the fix. Interior hinges live in a stable, dry environment and rarely wear out at all; when an interior door starts dragging, it is almost always loose screws or a settled jamb rather than a failed hinge. Exterior hinges carry heavier slabs, face Ottawa's weather, and take the salt and moisture of winter, so they genuinely wear and rust and need replacing on a real schedule. They also matter more — a worn exterior hinge that lets the door drop breaks the weatherseal contact and lets in cold, so it costs you comfort and heat as well as a smooth swing. That overlap with sealing and drafts is covered in our drafty front door guide.

Adjust first, replace if needed

Not every loose door needs new hinges. Often the fix is replacing stripped screws with longer ones that bite into the framing, or shimming a hinge to bring the slab back square. When the hinge itself is worn, it gets swapped — matching the size, finish, and radius of the corners so the door still closes true. This is routine front door repair, and on heavier or commercial slabs it overlaps with closer and hardware work.

Do not wait it out

A failing hinge shifts load onto the frame and latch. Left alone, a cheap hinge fix turns into frame repair. If your door is dragging or dropping, have the hinges checked before the jamb wears. We carry common hinges on the truck and fix most in one visit.
