A window in its own opening
Replacement windows go into the opening you have, then are trimmed and sealed. A same-size swap leaves the size, support and exits alone.

Window replacement in Thornhill and new window installations, measured opening by opening, on their own or alongside your front and garage doors. Estimates are free.

What’s included
Windows for a Thornhill house are measured to each opening and ordered, 15 minutes from the shop; a window in the same opening needs no building permit from the City of Vaughan or the City of Markham, a larger opening or a new window where there was none is a structural change that City of Vaughan Building Standards (west of Yonge Street) or City of Markham Building Standards (east of Yonge Street) reviews, and on a designated house in one of its heritage districts the heritage permit comes first.

Replacement windows go into the opening you have, then are trimmed and sealed. A same-size swap leaves the size, support and exits alone.
02New
A window where there was none, or a bigger one, is a different job: drawings, a lintel and inspections can come with it.
03Exits
The replacement keeps a style and sash that meet the opening size, because the window in a bedroom must open without tools from inside.
04Fit
Gas fill, glazing and frame come from the U-value or the energy rating specified. Sealing against the air barrier follows.

I’m very happy with the work done on my front door and garage door. … Both doors look amazing …
Everyone else told me I’d be waiting anywhere from 6 weeks to 4 months just to get a door delivered and installed.
My garage spring and cables snapped on a Sunday afternoon, Moe was able to swing by the next morning …
Great Service by Moe, very clean job, on time and no surprises.
It completely changed the look of my home and has already received so many compliments.
The work was done in 5 hours and they cleaned up after themselves leaving no trace of my old garage door and front door.
I called Moe he was here in the same hour and we got our new doors in two days
He didn’t just fix the immediate problem … made sure the door was running smoother and quieter than before.
We were presented with multiple options and given the pros and cons of each.
… replacing my destroyed garage door for a beautiful modern style door.
Replaced my front door and garage door with a remote. … the finished work looks amazing.
I had a quote within a day … and the new door installed by that weekend.
Garage door spring was broken. Moe was able to come out the next day and fit it.
Moe takes the time to get to know what your needs are and has affordable recommendations.
Moe did an excellent job replacing our old, worn down garage door with a beautiful, heavy duty white one.
… he was here the next day and we had our garage doors and front doors done within one week.
The whole process was seamless and I couldn’t believe how fast the job was completed without any hiccups.
… came on short notice to take a look. He quickly diagnosed the problem and had it fixed in no time.
They were super on time, super efficient, and the price was dead on.
Projects
Real jobs on our customers’ houses, recreated from the photos we took: the door we took down, and the one we hung in its place.
Both doors on one house.

The garage door and the front doors were both brown: raised panels with square lites, and double doors with grid lites in a white frame. We replaced them together in one grey, so the two now match across the front of the house.

FAQ
What Thornhill homeowners ask about window replacement, and the questions every door raises.
Not here? Ask us for a free estimate.
Three things decide it: how many openings there are, how large they are, and whether any is new or enlarged. A permit or heritage approval, which the Markham side of Thornhill can require, is a further step to plan around. You see the price before any work, and the estimate costs nothing.
That depends on how many openings are being done, and the day is booked once the estimate is agreed. What Thornhill can add is a step before the work: a permit when an opening is new or larger, or heritage approval for a street-facing window inside the Markham district. Windows can share a visit with a front or garage door.
A window replaced in its existing opening is the simple case, and a new, larger or moved opening is where the permit question begins. Which city to ask depends on the house's side of Yonge Street. The Markham heritage district is a separate question, since exterior alterations there are approved before the work is booked.
The district rule covers exterior alterations to every property in it, not only the street side, so removing and replacing a window anywhere on the house is a Minor Heritage Permit project. It carries no fee, and the crew asks whether the house is in the district before it books a date.
Yes. The same crew installs front doors and windows as well as garage doors and openers, so one booking can cover a garage door, a front door and windows if you want the whole front of the house done at once. Photos and an address are enough for the estimate.
Check three things before you call anyone. Is the opener getting power, or has the plug come out or the breaker tripped? Is the door locked, or has the red release cord been pulled? And look at the springs above the opening: a gap of a couple of inches in a coil means one has snapped, often with a loud bang beforehand. If a spring is broken, do not force the door or keep pressing the button. Stop there and call (647) 323-1826, at any hour.
Yes. Modern Empire Doors is open 24 hours a day, seven days a week, holidays included, and the phone is answered at night. A door stuck open is a security problem, and a door stuck shut with the car inside is a lost day, so neither waits for Monday. Some things can wait for a weekday: a noisy door, a remote that stopped while the wall button still works, a torn seal. If you are not sure which yours is, call and ask.
Usually, yes. The parts that fail most often are carried on the van, so most repairs are finished on the first visit. If you text a photo from inside the garage before we come, we can often see what has failed and make sure the right part is with us. The exceptions are parts made for one door, such as a replacement section in a matching design and colour, which may have to be ordered in. In the meantime the door can usually be secured so the garage still locks.
It depends on the part, and most repairs come down to a handful: springs, cables, rollers, the opener or the safety sensors. We would rather tell you the real price for your door than quote a range that does not apply to it, so text a photo from inside the garage to (647) 323-1826 and we can usually tell which part it is before we arrive. Most repairs are finished in one visit, and you hear the price before any work starts.
Often, if the same section is still made. What people call a panel is usually a full-width section, and the new one has to match the make, size, design and colour of the rest. On a newer door from a current series that is usually possible. On an older or discontinued door it may not be, and a mismatched section can look worse than the dent. Sun-faded finishes are the other catch. Send a photo, plus any label on the door's inside edge, and we will tell you honestly.

Each opening is measured on its own, so one that has settled is measured as it stands and the window is ordered for that size, not for a standard one.

Photos of the windows and the address are enough to start. Every opening is measured on its own before anything is ordered, and the estimate costs nothing.

A replacement window goes into an opening that already exists. A new installation makes an opening where the wall had none, and that is where a permit question begins. The crew does both.

The guide
What is different about window replacement in Thornhill: the houses, the rules and the drive from the shop.
The work covers replacement windows and new window installations, with each opening measured on its own. It can be a single window or a whole house, done separately or on the same booking as the doors.
The same crew handles the front door and the garage door, which makes one visit possible for the whole facade. Thornhill is 9.7 km from the shop, about 15 minutes by road, and the estimate is free.
Yonge Street is the boundary between Vaughan and Markham in Thornhill, and a new, larger or moved opening is taken to whichever city holds the house's side of it.
In the Markham heritage conservation district, an exterior alteration is approved before the work is booked, and heritage staff are delegated authority to approve work that follows the district policies and guidelines. A street-facing window falls under that, so the crew confirms whether the house is inside the district first. Replacing windows is a Minor Heritage Permit project, and Minor applications carry no fee.
