Door Won’t Close Ottawa

A door that won’t close is one of those problems that feels minor right up until the temperature drops. In July it’s an inconvenience — you push it a bit harder, it closes most of the way, life continues. In January it’s a different story. Cold air pouring through a door that won’t seal properly drops the entry temperature immediately, sends your furnace into overdrive, and if the gap is large enough, risks pipe freeze near exterior walls. At Fix My Door Now Ottawa, we treat a door that won’t close with the same urgency as a lock failure — because in the Ottawa winter, it effectively is one. We respond the same day and resolve the issue in a single visit in the large majority of cases.

The interesting thing about a door that won’t close is that the cause is almost never what people assume it is. People assume the door has warped, or the frame has swollen, or something has physically changed about the door itself. Sometimes that’s true. More often, the problem is something smaller — a hinge that has loosened by two millimetres, a threshold that has risen slightly, a frame that has shifted just enough to narrow the opening at one corner. These are invisible changes that produce a very visible and very frustrating result.

The most common reasons a door won’t close in Ottawa

Hinge loosening and door sag

The most frequent cause we find on residential Ottawa doors is hinge loosening on the top hinge. As that hinge works loose, the door pivots on the middle and bottom hinges and the latch side of the door rises — the opposite corner from where the loose hinge is. The top of the latch side catches on the door stop or frame, and the door won’t close past that point without significant force. Homeowners often try to force it, which accelerates the damage to the frame and the hinge further. The fix is straightforward: restore the top hinge to its correct position with appropriate fasteners, and the door returns to its correct swing.

Seasonal wood swelling

Ottawa’s summers are genuinely humid, and wood exterior doors absorb that humidity and expand. A door that closes perfectly in February can bind solidly in August as the wood swells across its width and height. The binding typically appears at the top of the latch side or along the hinge side near the top — the points where the door has expanded enough to contact the frame. This is one of the few cases where the door itself is the issue rather than the hardware. We assess the degree of swelling and the door’s history before deciding whether to plane the door or adjust the frame — because a door planed too aggressively in summer will have significant gaps in winter when it shrinks back.

Frame movement and racking

Ottawa houses move. The ground freezes and thaws, foundations shift incrementally, and the door frames that were plumb and square when installed are no longer perfectly so after a decade of seasonal cycling. A frame that has racked — shifted out of square — narrows the opening diagonally, producing a door that fits in one orientation and won’t close in the one the frame has moved to. This shows up as a door that makes contact at one corner when it’s pulled closed and leaves a gap at the opposite corner. Frame adjustment or re-shimming corrects the rack and restores the closing clearance.

Threshold problems

A threshold that has risen — through settling, frost heave under the sill, or warping — can prevent a door from closing by blocking the door bottom before the door reaches the latch. This is particularly common on exterior doors that open outward over a threshold that sits proud of the surrounding deck or step surface. The door swings and contacts the threshold lip before it’s fully closed. We adjust or replace thresholds and correct the sill condition where it’s causing the obstruction.

Damaged or bent hinges

A hinge that has been bent — from a door swung too hard, a heavy impact, or years of being forced against an obstruction — no longer holds the door in its correct plane. The door sags or twists as it swings, contacting the frame at a point it wasn’t designed to contact. Bent hinge leaves can sometimes be straightened; more often, replacement with a correctly sized commercial-grade hinge is the right answer. We assess all three hinges, not just the one that looks damaged, because forces transmitted through a damaged hinge affect the others.

Storm and impact damage

Ottawa windstorms, ice storms, and the occasional vehicle impact can physically damage a door or frame enough that the door no longer closes correctly. A door blown fully open against its stop can damage the hinge, bend the door at the stile, or crack the frame at the hinge mortise. We see this after significant weather events across Ottawa — an ice storm that caused doors to freeze and then be forced, a windstorm that drove a door into its frame with enough force to damage the stop. Post-storm door assessment is something we offer across Ottawa, and identifying and repairing storm damage early prevents it from becoming a much larger structural repair later.

The latch is catching before the door is fully closed

Sometimes the door physically closes — the slab reaches the stop — but bounces back because the latch can’t compress far enough to clear the strike plate lip. This happens when the strike plate has moved slightly outward, when the latch mechanism is sluggish and not fully retracting before contact, or when the door is closing at a slight angle that presents the latch at the wrong geometry to enter the strike. We adjust the strike, service the latch mechanism, or correct the door alignment depending on what the assessment reveals.

Why this matters more in Ottawa than elsewhere

Ottawa’s temperature range is one of the widest of any major Canadian city. The thermal cycling that this produces moves door assemblies more than in milder climates, and the humidity swing between summer and winter is substantial enough to cause real dimensional changes in wood. A door that closes correctly at one point in the year may not at another — and because the change is gradual, people adapt to it rather than fixing it, pushing a little harder in summer, shouldering it in winter, until the day it simply won’t go. We calibrate repairs for Ottawa’s full seasonal range, not just for the condition on the day we arrive.
