Window Replacement in Courtice, ON
Oshawa Prestige Windows & Doors does window replacement in Courtice, ON, for the kind of house this town is full of: a two-storey or side-split built sometime after 1985, still wearing its original builder windows. We swap tired sliders for casements and awnings that actually seal, fit new glass where the old units fogged, and replace front and patio doors. One crew does it all, start to finish.
Courtice starts at Townline Road, the Oshawa line, so most mornings our trucks are here before the coffee's cold. Same installers, same standards. If you searched window replacement Courtice and found mostly Toronto outfits, that's the difference. Further east we cover Bowmanville and the rest of Clarington. Thinking about ditching the sliders? Our page on casement and awning windows explains the swap.

Courtice Homes Built in the 1980s and 1990s
Courtice was a small rural village until the mid-1980s. Then the subdivisions arrived, and the population grew fast until things cooled off in the mid-1990s. By the 2021 census it had 22,893 people. In plain terms, most Courtice windows are now 25 to 40 years old. That's about the end of the road for builder-grade vinyl.
You know the signs. Sliders that stick in the track. Cranks that spin and don't open anything. Glass that looks foggy no matter how often you clean it. The fog is the big one: it means the seal around the sealed unit has failed, and the gas between the panes has leaked out. Most of these houses got vinyl windows from the builder, and builder grade was never meant to last forty years.
Why are my Courtice windows foggy between the panes?
Fog between the panes means the edge seal of the glass unit has failed. Moist air gets in, and it condenses inside where you can't wipe it. Many Courtice homes from the late 1980s and 1990s are reaching that point now. The fix is new glass in a sound frame, or a whole new window when the frame is worn too.
Retrofit or Full-Frame on a 1990s Courtice Home
Retrofit installation (the old frame stays and the new window slides into it) works on most Courtice homes. The frames are vinyl, they're rarely rotten, and the job goes quickly. It's like a crown on a healthy tooth. But the estimator still puts a moisture meter on every wood sill first. A soft one means full-frame replacement for that opening, no exceptions.
Doors wear out here too. On a recent job in Courtice, a 1970s side-split, the windows were fine but the doors weren't. We put in a fibreglass entry door. Two sidelites went in beside it. The same day, a new 6-foot sliding patio door went in at the back, and the bill came to between $8,000 and $10,000. The owners told us the front hall stopped feeling like a mudroom in January.
Noise from King Street and Highway 401
King Street is Highway 2 through Courtice, and it went from two lanes to five in 1988. On the south edge, Courtice Road meets Highway 401 at Interchange 425. If your bedroom faces either one, you know the night trucks. Glass makes a real difference here.
Two upgrades do most of the work. Laminated glass has a thin plastic layer bonded between two sheets, and that layer soaks up sound. Triple pane adds a third sheet and a second air space. We'd pick laminated glass for a bedroom on King Street, and triple pane where cold matters as much as noise. Either way the gap around the frame gets low-expansion foam. Sound leaks through gaps first.

Window and Door Replacement Options in Courtice
What we swap most in Courtice, roughly in order of how often the phone rings about it.
Slider to Casement Swap
Builder sliders were cheap to install in the 1990s, and they leak air along the track. A casement window cranks shut and presses its sash into the seal on all four sides. Most Courtice openings take the swap without any change to the brick.
Awning Windows
An awning window is hinged at the top and opens out from the bottom. Pair one under a big fixed pane and you get the view plus fresh air. It's also the window you can leave cracked open in a light rain.
Picture Windows
A picture window doesn't open at all, so it has the best seal and the biggest glass for the money. Courtice living rooms often get one in the middle with an operating casement on each side for air.
Front Entry Doors with Sidelites
Original 1990s steel doors dent, rust at the bottom and leak at the weatherstrip. A new fibreglass door won't dent and can be painted or stained. Sidelites on one or both sides bring daylight into the front hall.
Sliding Patio Doors
If your patio door drags, whistles or fogs up, the rollers and the glass seal are done. We replace the whole unit, frame and all, and finish the inside trim the same day. Blinds sealed between the glass are an option, so there's nothing to dust.
Basement Hopper Windows
A hopper window tips in from the top, which suits a small basement opening above a window well. New units seal far better than the single-pane basement glass many Courtice homes still have. Planning a basement bedroom? Ask about egress sizes first.
Courtice Window Replacement FAQ
Do I need a permit to replace windows in Courtice?
Usually not. Under the Ontario Building Code, replacing a window or door of the same size in a house is normally permit-free in Clarington. Bigger openings are different. Making one larger, or cutting a new one where there was only wall, needs a building permit, and we'll tell you at the quote if your plans cross that line.
How long does it take to replace windows in a Courtice house?
One day, most of the time. A typical 10-opening house is done in one day by our two-person crew, and full-frame jobs take one to two. Each opening is open to the weather for only a few minutes while the old unit comes out and the new one goes in, and we clean up as we go, so you can stay home the whole time.
Is there a rebate for new windows in Ontario?
Ontario's Home Renovation Savings Program has offered $100 per window or door. The unit has to be ENERGY STAR certified, and you need a home energy assessment before the work starts. Program rules and end dates can change, so check the current terms before you sign anything.
Can windows be replaced in a Courtice winter?
Yes, we install all year in Courtice. Only one opening is open at a time, usually for a few minutes, and we seal each unit before moving to the next. Winter dates are often easier to get than spring ones, when everyone remembers their drafty windows at once.
What warranty comes with the installation?
Our installation work carries a limited 5-year warranty, on top of the manufacturer's warranty on the window or door itself. We also carry $5 million in liability insurance and WSIB coverage on every job. If something isn't right after the install, a service technician comes back to fix it.
Are triple pane windows worth it in Courtice?
On some walls, yes. Triple pane pays off on north-facing rooms and on bedrooms facing King Street or the 401, where it cuts both cold and noise. On a sheltered south wall, good double pane glass with Low-E does nearly as well for less money. We'll tell you which walls deserve it.
