How to Fix a Sticking Door in Calgary

Why Calgary doors stick more than most cities

Calgary has one of the widest humidity swings of any Canadian city. Indoor relative humidity in a Calgary home can drop below 15% during a January cold snap with the furnace running flat out — and climb above 60% in a humid August week. That swing causes solid wood door slabs (and even hollow-core doors with a wood composite core) to expand and contract measurably over the year.

A door that closes perfectly with a satisfying click in January may require a hip-check to close in July. This is not a defect — it is wood responding to moisture in a continental climate. The question is whether the sticking is seasonal (fix: patience or light sanding) or structural (fix: hinge work, plane, or frame adjustment).

Calgary's expansive clay soil adds a second variable. Foundation movement in clay-heavy areas — particularly in the established NW, SW and inner SE — can shift door frames by 3 to 5 mm over a decade, which is enough to take a well-hung door from smooth to stuck. This type of sticking shows up consistently year-round rather than seasonally.

Step 1: Identify where the door is binding

Before touching anything, identify exactly where the door is touching the frame. Close the door slowly and watch the gap between the door edge and the frame:

• Top hinge corner dragging — the door is sagging. This means the top hinge is loose or the screws have stripped out of the frame or door. Most common cause of sticking in older Calgary homes.
• Latch side edge rubbing — the latch side of the door is too close to the frame. Caused by hinge sag, frame shift, or the door slab swelling in summer humidity.
• Bottom edge dragging on the floor — hinge sag (door dropped), or the floor has heaved slightly. Occasionally caused by carpet replacement that added height to the floor level.
• Top of door rubbing — frame shifted up or the door slab expanded top-to-bottom. Less common than side binding.
• Deadbolt not throwing — the bolt aligns with the strike plate but the bolt does not enter cleanly. This is a frame alignment issue, not a lock defect in most cases.

Mark the binding spots with a pencil or chalk while the door is closed. This tells you exactly where to focus and prevents guessing.

Step 2: Check the hinges first

Hinge sag is the most common cause of a sticking door in Calgary homes and the easiest to fix. A door that drops 2 to 3 mm at the latch side will bind against the latch-side frame. The fix:

1. Open the door fully and look at each hinge. Are any hinge screws loose? Can you wiggle the hinge plate?
2. With a screwdriver, try tightening every hinge screw. If they tighten and hold — close the door and test. Problem solved in under 5 minutes.
3. If a screw turns but will not tighten, the screw hole in the frame is stripped. The fix: remove the screw, fill the hole with a wooden toothpick and a drop of wood glue, let it dry for 30 minutes, and reinstall the screw. This provides enough fresh wood for the screw threads to grip.
4. If the hinge itself is loose from the door slab (rare), the fix is longer hinge screws — 3-inch screws that penetrate through the door jamb into the structural framing behind it. This is called a “security hinge screw” repair and is the most durable fix for persistent hinge sag in Calgary's older homes.

Step 3: Assess seasonal vs. structural sticking

If the hinges are tight and the door still binds:

Test in both seasons if possible. If the door sticks in summer but closed easily in March, it is almost certainly seasonal wood swelling. The fix options are:

• Do nothing and wait for September — the door will ease as humidity drops
• Sand the binding edge lightly with 80-grit — mark exactly where it binds and sand only that area; you can always take more off but you cannot put it back
• Seal all door edges with primer or paint if they were not sealed originally — bare wood absorbs moisture faster than sealed wood

If the door sticks year-round, the cause is structural: frame shift, foundation movement or a door that was installed slightly out of square originally. These require physical adjustment to the frame or the door position — not something to sand your way past.

What a handyman fixes — and how

Planing the door edge

For a door that binds on the latch side and the hinges are sound, planing the binding edge is the correct fix. This requires removing the door from the hinges, identifying the exact binding line, and using a hand plane or belt sander to remove material from the correct face. Painting the planed edge afterward seals it against moisture.

Planing is not a DIY-friendly job without the right tools. A hand plane requires practice to use without gouging. A belt sander removes material quickly but can take too much off in a short pass. A handyman who does this regularly can plane a door edge in 15 to 20 minutes without removing the door from the frame in many cases — using a sharp block plane on the high spot while the door is still hung.

Strike plate adjustment

A deadbolt that is stiff, does not throw fully or requires lifting the door slightly to close is almost always a strike plate alignment issue. The latch bolt or deadbolt is hitting the face of the strike plate rather than entering the hole cleanly.

Quick diagnostic: smear lipstick or chapstick on the end of the bolt, throw the bolt against the door closed, and open the door to see where the bolt contacted the strike plate. If the mark is above or below the strike plate opening, the plate needs to be moved.

The fix: enlarge the strike plate opening with a file, or remove and reposition the plate. Repositioning requires filling the old screw holes and mortise, and cutting a new mortise in the correct position — a 20 to 30 minute job done properly. Enlarging the hole with a file is faster but is only appropriate for small adjustments (1 to 3 mm).

Full frame adjustment

When frame shift has moved the door out of square — the jamb has rotated or racked due to foundation movement — adjusting the strike plate and hinges may not be enough. A full frame adjustment involves shimming behind the hinges to push the door slab back into square relative to the frame. In severe cases, the stop moulding on the frame needs to be repositioned.

This is a handyman job. It requires assessing the full swing of the door with a spirit level, identifying the source of the shift, and adjusting multiple contact points systematically. Getting it wrong — shimming too much at one hinge or moving the stop moulding in the wrong direction — creates a different binding problem.

Exterior doors: additional Calgary considerations

Exterior doors in Calgary face additional stresses that interior doors do not:

• Threshold heave — the threshold strip at the bottom of an exterior door can heave from frost underneath the concrete step, lifting the threshold and causing the door to drag. This looks like floor-to-door binding but the door is fine — the threshold needs to be reset or replaced.
• Weatherstripping compression — thick weatherstripping on an exterior door door that was recently replaced can make the door feel stiff to close even if the door itself is perfectly hung. Check the weatherstripping compression before assuming the door needs adjustment.
• Steel door warping — fiberglass and steel exterior doors are less prone to moisture warping but can still warp due to extreme temperature differentials (direct sun on the face, cold air on the back). A warped steel door requires replacement in most cases.
• Door closer issues — storm door or self-closing door closer mechanisms wear out in Calgary's cold temperatures. A closer that feels stiff below -20°C is normal; one that holds the door open or slams it shut needs adjustment or replacement.

When to call a handyman vs. DIY

What it costs to have a door fixed in Calgary

A handyman door repair starts at $65 for a door adjustment — hinge tightening, plane and sand, or minor strike plate adjustment. A deadbolt replacement where the mechanism is worn starts at $85. Diagnosis is included in either case — there is no site visit charge to assess what is wrong before quoting the fix.

For homes with multiple sticking doors — common in 1980s and 1990s Calgary builds after decades of settle — batching all the doors into one visit is more cost-effective than separate appointments.
