Door and Window Repair in Woodbridge: Reseal, Adjust, or Replace? (2026)

Published 2026 — Rhodex

A drafty Woodbridge door or window is usually one of three fixes: resealing ($70–$220), a hardware adjustment ($110–$280), or full replacement (from $650). Fogged glass trapped between the panes always means replacement — caulking or adjusting won't fix that.

A drafty exterior door or a window that whistles when the wind picks up almost always gets one of two guesses: "it needs new caulking" or "it's time to replace it." Both are sometimes right, and both are sometimes an expensive way to fix the wrong thing. The actual decision comes down to which of three separate things has failed — the seal around the frame, the hardware that holds the sash or door tight, or the unit itself — and each one has a genuinely different price tag. Reseal work in Woodbridge typically runs $70–$220. A hardware adjustment lands at $110–$280. Full replacement starts around $650 for a standard window and climbs well past $1,600 for the larger, custom sizes common in this area. Getting the diagnosis right is most of the job.

Start by finding what's actually letting air or water through

A cold draft on your hand near a window frame usually means the perimeter seal — caulking on the outside, weatherstripping on the moving parts — has dried out, cracked, or come loose. A door or window that's hard to latch, doesn't sit flush, or has started sagging on one side usually means the hardware underneath has shifted, not that the unit is failing. And condensation or fog trapped between two panes of glass — not on the inside surface, which is just humidity, but actually sealed inside the glass unit itself — means the insulated glass unit has failed, and no amount of caulking or adjustment reaches that. Those three symptoms point to three different jobs, and mixing them up is the single most common way homeowners overpay: caulking over a hardware problem doesn't fix it, and replacing a whole window over a caulking problem is money that didn't need to be spent.

Reseal: a draft, not a defect

If the frame itself is square, the glass is clear, and the door or window still opens and closes properly, a worn perimeter seal is usually the actual cause — exterior caulking has a realistic lifespan of about 10-15 years before it cracks and pulls away, and rubber or foam weatherstripping on a door or an operable window sash degrades faster than that, especially on south- and west-facing exposures that take the most sun. Re-caulking a single window's exterior perimeter runs $70–$150; replacing worn weatherstripping around one exterior door, including the bottom sweep, is typically $120–$220. Because most of the cost on a job this size is the service-call minimum rather than materials, a whole-house resealing pass — every window and both exterior doors in one visit — commonly runs $700–$1,300 total in a typical Woodbridge home, well under what the same list would cost booked one at a time.

Adjust: when the hardware is the actual problem

A door that's started dragging on the floor, a window that won't stay up without a prop, or a lock that lines up wrong is very rarely a sign the unit needs replacing — it's almost always the hardware that's shifted, and that's a genuinely different repair. Common causes: hinge screws that have worked loose in a wood jamb over the years, a strike plate that's drifted out of alignment as the house settled, a window's sash balance or spiral tension losing its grip so the sash won't hold its position, or a slider's roller track filling with grit until the panel starts binding. Re-setting hinges or a strike plate on an exterior door is typically $110–$200; replacing a failed window balance or roller assembly runs $150–$280 per window, since it usually means removing the sash to get at the mechanism. This category is worth checking first on an older Woodbridge home before assuming a window "just needs replacing" — houses built through the 1970s to 1990s have had 30 to 50 years of normal settling, and settling shows up in hardware alignment long before it shows up in the glass.

Replace: when the seal that failed is inside the glass, not around it

Fogging or a hazy film trapped between the panes — that doesn't wipe off from either side because it's sealed inside the unit — means the insulated glass unit's internal seal has broken down and the gas or dry air between the panes has been compromised. That's not repairable by caulking, adjusting, or cleaning; the sash or the whole window has to be replaced. The same applies to a frame that's visibly rotted, warped enough that the sash won't seat squarely no matter how the hardware is adjusted, or a door slab that's delaminating. A standard-size replacement window (vinyl, double-pane, installed) runs $650–$1,100 in Woodbridge. The real local wrinkle: this area's larger custom-built homes carry more bay windows, picture windows, and oversized living-room or primary-bedroom windows than a standard subdivision does, and those non-standard sizes are usually special-order rather than off-the-shelf — realistically $1,600–$4,200+ depending on size and configuration, with several weeks' lead time to manufacture rather than a same-week install. An insulated steel or fibreglass exterior door, installed, typically runs $1,900–$3,800 depending on hardware and whether the existing frame can be reused.

When this crosses into a City of Vaughan building permit

Replacing a window or door in its existing rough opening — same size, same location — is treated as maintenance and doesn't require a City of Vaughan building permit. The line moves once the opening itself changes: enlarging a window to a bigger size, or converting a small basement window into an egress window, does require one. That last case comes up more than people expect in an older Woodbridge basement: if a below-grade room is being used or finished as a bedroom, Ontario's Building Code requires that room to have a window that can serve as an emergency exit — an unobstructed openable area of at least 0.35 square metres, with no dimension smaller than 380 mm, operable from inside without a key or tool. A lot of older basement windows in this area's original builds don't meet that on their own, which turns what looks like a simple window swap into an opening-enlargement job with a permit attached. Worth asking directly, before booking, whether the room the window serves is a bedroom — it changes the scope of the job, not just the price.

Bundling doors and windows in one visit

Because the service-call minimum is the biggest fixed cost on jobs this size, a single visit that resolves several problems at once is worth planning for rather than booking each one separately. A realistic whole-house tune-up — resealing three or four drafty windows, adjusting a sticking door, and replacing one failed sash — commonly lands around $900–$1,500 total, noticeably less than the same list of jobs spread across separate calls, and it means one afternoon of disruption instead of three.

Quick answers

How do I know if my window needs resealing or replacing?

It depends which of three things has failed. A cold draft usually means the perimeter seal, a door or window that's hard to close or sits crooked usually means the hardware, and fog trapped between the panes means the glass unit itself has failed and needs replacing.

How much does it cost to reseal a window in Woodbridge?

Re-caulking a single window's exterior perimeter runs $70 to $150. Replacing worn weatherstripping around one exterior door, including the bottom sweep, is typically $120 to $220.

How much does window replacement cost in Woodbridge?

A standard-size replacement window, vinyl, double-pane, installed, runs $650 to $1,100. Woodbridge's larger custom-built homes often need special-order bay, picture, or oversized windows, realistically $1,600 to $4,200 or more.

Do I need a permit to replace a window in Vaughan?

Not if it's the same size and rough opening — that's treated as maintenance. A City of Vaughan building permit is needed once the opening changes size, such as enlarging a window or adding a basement egress window.

Who can fix a drafty door or window in Woodbridge?

Rhodex can send a vetted craftsman; request a quote at rhodex.ca/get-a-quote.html. Ask them to point to exactly what's failing — the seal, the hardware, or the glass unit — before agreeing to a replacement.

Diagnose before you decide

The fix that actually solves the problem depends on where the failure really is, not on how old the door or window looks. A 40-year-old wood window with tight, clear glass and a loose sash cord needs an adjustment, not a $900 replacement. A 5-year-old vinyl window with fogged glass needs the sash replaced regardless of how new the frame around it looks. Before agreeing to anything, ask whoever's quoting the job to point to exactly what's failing — the seal, the hardware, or the glass unit — rather than accepting "it needs to be replaced" as the default answer to a draft.
