How Long Should a Door Last?

A good exterior door should give you decades, not years. When one fails early in Ottawa, it is usually the climate, the install, or a part that was never maintained — not the door itself wearing out.

Typical lifespans

A quality steel or fibreglass entry door lasts 25 to 30 years or more. A wood exterior door can last as long with upkeep, but it is more sensitive to moisture. Interior doors often outlive the rest of the house. Patio and sliding doors run 20 to 30 years, though the rollers, seals, and sealed glass units wear out sooner and get replaced along the way. The slab usually outlasts its hardware several times over.

What shortens a door's life in Ottawa

Our climate is hard on doors. The freeze-thaw cycle, road salt, wind-driven rain, and the swing from humid summers to dry cold all take a toll. Two failures stand out: water getting into the frame, which leads to rot, and seals breaking down so the door leaks heat and the slab swells and shrinks. Both are avoidable with maintenance.

The parts that wear first

Long before a door needs replacing, its hardware does. Hinges loosen and sag — watch for the signs hinges need replacing. Weatherstripping and the door sweep harden and leak. Locks and latches drift out of alignment. Replacing these on schedule is what keeps a 10-year-old door performing like new, and it is far cheaper than a new unit.

Lifespan by door type

Not every door ages the same way. A front entry door takes the most abuse — weather on one side, daily use, and the full force of Ottawa's seasons — so its seals and hardware need attention every few years even though the slab is good for decades. Patio and sliding doors are a different story: the rollers, the track, and the sealed glass unit are the parts that fail, and they fail well before the door is done. If yours has fogged glass or drags on the track, that is a roller or seal job, not a sign the whole unit is finished. We cover that in our patio door repair vs replacement guide and through patio door repair. Interior doors, closet doors, and bifolds rarely wear out at all; when they fail it is almost always the hardware or the jamb, which is a quick fix through hinge and hardware repair.

The cost angle: maintenance vs replacement

The reason lifespan matters is money. A full door replacement — slab, frame, hardware, and install — is one of the larger home expenses, while the wear parts that actually fail cost a fraction of that. Replacing weatherstripping, swapping a worn hinge, or resealing a threshold is routine maintenance, not a major project, and doing it on schedule is what stretches a door from 15 years to 30. Letting those small items slide is what turns a cheap fix into a real bill: a leaking seal lets water reach the frame, the frame rots, and now you are looking at structural work or a new unit. For a sense of what the common fixes run, see our Ottawa door repair cost breakdown.

A simple maintenance routine

Most of what shortens a door's life is preventable with a short routine twice a year. In the fall, before the cold arrives, run your hand around the closed door on a windy day and feel for drafts; a candle flame or a slip of paper pinched in the closed door tells you where the seal has gone. Check that the threshold is sealed and that water drains away from the sill rather than pooling against it. Tighten every hinge screw, and look at the bottom hinge on exterior doors for the rust that Ottawa road salt brings on. In spring, look for swollen or soft spots low on the jamb where snowmelt sat all winter — caught early, that is a seal and paint job; caught late, it is rot. Ten minutes twice a year is what separates a door that lasts 30 years from one that fails in 12.

Signs your door is near the end

A door that has truly reached the end of its life shows it in ways a tune-up cannot fix. Soft, spongy wood at the bottom of the slab or jamb means rot has set in past the surface. A slab that has visibly warped or bowed so the seal cannot make contact along its whole length is past adjustment. Cracks through the slab, a frame that has racked out of square from settling, or daylight you can see around a closed door all point toward replacement rather than repair. If you are seeing those, it is worth a straight assessment — and our cost guide helps you weigh the repair against a new unit.

When repair beats replacement

If the slab is sound and the frame is solid, repair is almost always the right call — new hinges, fresh seals, a tuned-up latch, and the door is good for years more. Replacement makes sense when the frame has rotted through, the slab is split or warped, or an old door is leaking so much heat that the energy savings justify it. A sagging door is a repair; a rotted, racked frame may not be. For patio doors, the same logic is in our repair vs replacement guide.

Make yours last

Keep water out of the frame, replace seals before they fail, and fix alignment early. If your door is showing its age, we will tell you straight whether a repair buys you years or whether replacement is the smarter spend. Book front door repair and we will assess it flat-rate.
