Window & Door Hardware Repairs Toronto & GTA

A window or door that will not open, close, lock, or seal properly is more than an annoyance - it is a security risk and a source of energy loss. OhMyGlass repairs and replaces window and door hardware across the Greater Toronto Area. From a stripped window crank to a broken patio door roller, our technicians diagnose the problem on-site and carry common replacement parts to complete most repairs in a single visit. Hardware repair is often far less expensive than replacing the entire window or door, and it can restore full functionality to units that are otherwise in good condition.

What Hardware Do We Repair and Replace?

We work with all types of window and door operating hardware found in residential and commercial buildings.

• Crank handles and operators - the gear-driven mechanism that opens and closes casement and awning windows. When the gears strip, the handle spins freely without moving the sash.
• Hinges - friction hinges on casement windows and butt hinges on doors. Worn or corroded hinges cause sticking, sagging, and difficulty closing.
• Locks and latches - sash locks on double-hung windows, multi-point locking systems on doors, deadbolts, and commercial door locks. A broken lock compromises security immediately.
• Window balances - the spring-loaded mechanisms (block-and-tackle or spiral) inside the jambs of double-hung windows that hold the sash at any position. When a balance fails, the sash will not stay open or slides down on its own.
• Weatherstripping - the flexible seals around sashes, meeting rails, and door frames that block drafts, rain, and dust. Worn weatherstripping is one of the most common causes of energy loss around windows and doors.
• Rollers and tracks - the wheels and channels that allow sliding windows and patio doors to glide smoothly. Worn rollers or damaged tracks cause dragging, sticking, and difficulty locking.
• Handles and pulls - door handles, window lift handles, and pull hardware that wear out or break with daily use.

Common Hardware Problems and Solutions

Most hardware issues have straightforward solutions that our technicians can resolve on-site.

• Stripped crank - the gears inside the operator are worn. Solution: replace the operator mechanism and crank handle as a unit.
• Stiff or stuck hinge - dirt, paint, or corrosion is preventing smooth movement. Solution: clean, lubricate, and adjust, or replace the hinge if it is bent or corroded beyond repair.
• Broken lock - the latch or cam mechanism has failed. Solution: replace the lock hardware with a compatible unit and verify the keeper alignment.
• Sash that will not stay up - the balance spring has lost tension or the cord has broken. Solution: replace the balance mechanism in the jamb channel.
• Drafty window or door - weatherstripping has compressed, cracked, or fallen out. Solution: remove the old material and install new weatherstripping matched to the profile.
• Patio door that drags - rollers are worn, flat, or the track is bent. Solution: replace the roller assemblies and straighten or replace the track.

How to Maintain Your Window and Door Hardware

Regular maintenance extends the life of your hardware and prevents most common failures before they start.

• Clean tracks and channels at least twice a year with mild soap and water to prevent debris buildup that causes sticking and wear.
• Lubricate moving parts - hinges, operators, locks, and rollers - with a silicone-based spray. Avoid petroleum-based lubricants like WD-40 for long-term use, as they can attract dust and gum up over time.
• Inspect weatherstripping annually. Look for cracks, gaps, compression, or sections that have pulled away from the frame. Replace as needed.
• Tighten loose screws on hinges, handles, and lock hardware at least once a year. Loose screws accelerate wear on the surrounding material.
• Check window balances by opening a double-hung window halfway and releasing it. If it slides down on its own, the balance needs attention.
• Test all locks seasonally to ensure they engage fully and the keeper is aligned. A lock that does not fully engage provides no security.

When Should You Repair vs Replace the Entire Window or Door?

Hardware repair makes sense when the glass and frame are in good condition and only the operating mechanism has failed. A crank replacement, hinge swap, or new set of balances costs a fraction of a full window replacement and restores the unit to full functionality. Replacement of the entire window or door is more appropriate when the frame is rotted, warped, or structurally unsound, when multiple components have failed simultaneously, or when the unit is so old that replacement parts are no longer available. OhMyGlass evaluates both options on every job and recommends the most cost-effective solution.
