A sticking interior door in Woodbridge usually just needs planing or a rehang, not replacement, which runs about $95 to $250. A full slab or prehung swap typically costs $200 to $600 installed, more for solid-core doors or matched custom trim.
A door that drags on the floor, won't latch, or has a visible bow in the slab gets the same reflex reaction every time: replace it. Most of the time that's the expensive answer to a cheap problem. The actual fix depends on whether the wood has swollen with the season, the hinges have loosened, the frame itself has racked slightly out of square, or the door is genuinely warped or damaged beyond saving — and each of those is a different job with a different price.
What's actually making the door stick
A door that sticks only in summer and swings freely by winter is almost always wood reacting to humidity, not a structural problem — solid wood and even veneered slabs absorb moisture and swell slightly along the edge that's binding, then shrink back as the air dries out. A door that's been sticking the same way year-round, or that's started dragging low on one corner, points somewhere else: hinge screws that have worked loose in the jamb over the years, or a frame that's shifted slightly as the house has settled. Larger, older custom-built homes like the ones common in Woodbridge have had more decades for that settling to happen than a newer subdivision, so a frame going a few millimetres out of square isn't unusual on a home built in the 1970s through 1990s. None of that means the door itself needs replacing — it means something around the door has moved.
Planing and rehanging — when it's enough
If the slab is straight, the veneer or paint isn't cracked, and the problem is really just friction at one edge or a hinge that's dropped, planing down the binding edge and resetting the hinges typically runs $95 to $250, depending on whether it's a quick adjustment or the door needs to come off the hinges entirely to plane properly. A handyperson generally charges less per hour than a carpenter for this kind of work, but a carpenter often finishes it faster and with a cleaner edge — worth asking which you're getting quoted before comparing two numbers directly. If planing removes enough material to expose bare wood along the edge, budget separately for a touch-up coat of paint or stain to match, and for new hinge hardware if the old screws have stripped their holes in the jamb.
When the door itself is done
Two things actually retire a door rather than just needing an adjustment: a slab that's genuinely warped — visible bow or twist you can see by sighting down the edge, not just a stiff swing — or damage like a cracked panel, a punched-through hollow-core face, or water damage at the bottom from years near a bathroom or basement entry. Warping is more common in older hollow-core interior doors, which are a thin veneer skin over a mostly air-filled frame rather than solid material, so they flex and hold a warp under humidity swings in a way a solid-core door generally resists. Once a slab has warped, planing doesn't fix it — the door has to be replaced.
- Slab-only swap, existing jamb reusable and square: the door itself runs roughly $30–$80 hollow-core or $60–$330 solid-core, plus labour from about $150 per door for a straightforward fit — landing around $200–$350 installed for hollow-core, $350–$600 for solid-core.
- Full prehung replacement (new jamb and casing, needed when the existing frame is out of square or damaged): labour alone starts around $250 per opening with casing included, and closer to $300–$350 if the jamb and casing need to be custom-fit rather than a standard stock size.
Bundling several doors into one visit is worth planning for here the same way it is for other small jobs — a single service call covering three or four doors spreads the fixed minimum-visit cost across all of them, instead of paying it separately each time.
Matching trim in an older Woodbridge home
This is the part that catches people off guard in Woodbridge's larger, older custom builds more than almost anywhere else in the small-jobs run: the casing profile around your existing doors may not be a size or shape sold off the shelf at a big-box store today. Wider, more detailed casing profiles were common in custom homes built decades ago, and if you're replacing just one door in a hallway lined with matching trim, a mismatched casing profile stands out immediately next to the others. A millwork supplier can usually match or closely replicate an older profile, but it's custom-order rather than stock, which adds cost and lead time a standard prehung swap doesn't have. Worth asking directly, before booking, whether matching your existing trim is included in the quote or priced as an add-on — it's an easy detail to leave out of a fast estimate.
Do you need a permit for this?
Swapping an interior door in its existing opening — same size, same location, whether it's a slab-only fix or a full prehung replacement — is treated as maintenance, not construction, so it doesn't require a City of Vaughan building permit. That changes if the doorway itself is being widened or the framing around it is being altered, since that can affect a load-bearing header or wall; a project like that needs a permit and, depending on scope, a look from someone qualified to confirm what the wall is actually carrying.
The one interior door the building code actually regulates
Almost every interior door swap in a Woodbridge home has no code requirement attached to the door itself — except one. The door between an attached garage and the house is specifically regulated under Ontario's Building Code (section 9.10.13.15): it must be tight-fitting and weatherstripped, fitted with a self-closing device, and it can't open directly into a room used for sleeping. Where that separation requires a fire-protection rating, a 45 mm thick solid-core wood door satisfies a 20-minute rating (section 9.10.13.2) — a standard hollow-core interior door does not. If you're replacing the door from your garage into your house, that's the one interior door swap where "whatever matches the trim" isn't actually the whole answer; it's worth confirming the replacement is genuinely solid-core and self-closing, not just solid-looking.
Quick answers
How much does it cost to fix a sticking interior door in Woodbridge?
Planing and rehanging a sticking door, without replacing it, typically runs about $95 to $250. A carpenter usually charges more per hour than a handyperson, but finishes the adjustment faster.
Do I need a permit to replace an interior door in Woodbridge?
No, swapping a door in its existing opening is treated as maintenance, not construction. A permit only comes into play if you widen the doorway or alter the framing around it.
What kind of door does Ontario's building code require between my garage and house?
It must be tight-fitting, weatherstripped, and self-closing, and it can't open into a bedroom. Where a fire-protection rating applies, a 45 mm solid-core wood door satisfies the 20-minute rating most homes need.
Why do older interior doors warp or stick more in Woodbridge homes?
Many original hollow-core doors are a thin veneer over an air-filled frame, so they flex and warp with humidity swings more than a solid-core door. Decades of foundation settling can also rack the frame slightly out of square.
Who can I call for interior door replacement in Woodbridge?
Rhodex can send a vetted craftsman; request a quote at rhodex.ca/get-a-quote.html. Ask upfront whether matching your existing trim profile is included or priced separately.
Fix the cheap thing first
A door that's sticking, dragging, or won't latch properly is worth diagnosing before it's replaced — most of the time the wood, the hinges, or the frame moved a little, and the fix for that costs a fraction of a new door. Save the actual replacement for a slab that's genuinely warped or damaged, and when you do replace one, ask about trim matching and, if it's the garage door, about the code requirement most quotes won't mention unless you ask.
