We repair cranks, operators, locks, sashes, screens, drafts and leaks; replace foggy or cracked IGUs; and install full replacement windows when the existing system cannot be saved.
Complete Window Service
DoorWin works from the failed component outward. We repair hardware and operating problems, replace failed glass and seals, and install a complete replacement window when the sash, frame or full system is no longer practical to save.
Spinning handles, stripped gears, seized operators, bent linkage and worn hinges can often be repaired without replacing the full window.
A rusted casement window operator near Humberwood Park was replaced with a matching crank mechanism, restoring smooth opening, closing and locking.
Show example
Broken glass in bay, bow, picture and other fixed window sections can often be measured and replaced while a serviceable frame remains in place.
Broken bay window glass replaced in Whitby, restoring safety, curb appeal and clear residential glass without changing the whole window.
Show example
We separate perimeter caulking and weatherseal problems from glass seal failure, then repair the part of the opening that is actually allowing air or water through.
Failed exterior caulking around a panoramic corner window in Oakville was removed and replaced with new sealant around the glass and frame edges.
Show example
When condensation is trapped between panes or the insulated glass is cracked, we measure and replace the sealed unit while keeping a serviceable sash and frame.
Broken window glass in North York was replaced while the existing frame stayed in place, restoring the opening without full window replacement.
Show example
When the frame is damaged, the sash is beyond repair or the full system has failed, we measure the opening, remove the old unit, install the replacement window, insulate and seal the perimeter, and test final operation.
Renovating in Mississauga? DoorWin installed a new vinyl window in a rebuilt opening for cleaner fit, better insulation and a finished look.
Show exampleFor home windows that fog between panes, have a failed crank, stick, leak, fail to lock or need glass-only replacement. When the existing frame or full system cannot be saved, we also measure and install replacement windows.
Casement & Awning Windows
Window opens out but will not pull tight? Hinges, operator linkage and sash alignment are checked together.
Window Crank
Handle spins, jams or snaps? We match the crank, operator, linkage and hinge before replacing parts.
Sliding Windows
Slider drags, rattles or will not lock? Track condition, sash fit, rollers and lock alignment decide the fix.
Single & Double-Hung Windows
Sash drops, sticks or will not lock? Balances, tracks, locks and weatherseal are the usual causes.
Picture Windows
Fixed window has condensation between panes, poor sealing or edge failure? We check the sealed unit and frame pocket before recommending work.
Bay & Bow Windows
Bay or bow window feels drafty, sticks or has condensation in one section? We assess operators, seals, frames and sealed units by section.
Skylights
Skylight leaking, fogging or cloudy inside the unit? Seal, flashing, frame and roof access need to be reviewed first.
Window Screens
Screen torn, loose or missing? We repair or replace mesh and screen frames for everyday airflow.
For business and managed properties with foggy sealed units, leaking fixed windows, shifting aluminum frames, drafty storefront windows or unsafe commercial glass sections.
Commercial Windows & Storefronts
Commercial window opening leaking, shifting or unsafe? We check frame condition, seals, fixed panels and building access before scoping work.
Sealed Window Units / IGUs
Condensation trapped inside the sealed unit? We check whether the existing window frame can stay before recommending the next step.
Use the problem below - stuck window, broken crank, foggy glass or drafts - to open the right page. If you are unsure, send photos and we will point you to the right service.
For casement or awning windows with stripped handles, failed operators or windows that will not open or close correctly.
Foggy glassFor condensation inside sealed units where the frame can often stay and only the insulated glass is replaced.
CommercialFor business-facing window systems where glass, frame, seal and security requirements affect the repair path.
Send photos of the full opening and the failed area. We can identify whether the practical next step is crank or hardware repair, leak and seal work, screen service, IGU replacement or a complete replacement-window installation.

The staff are very polite, kind, and pleasant to deal with. The prices are more than reasonable, especially considering the high level of service — everything is top-notch.
