TL;DR
September–October and May–June are the easiest months to replace a front door in Ontario. Mild, dry days let foam and sealants cure properly.
Winter installs work. The door comes out and goes back in the same visit, and a good crew uses cold-rated foam and sealants.
For a custom door, the date that matters is the order date. Ours take 4–6 weeks to build before install day.
A drafty, damaged or insecure door shouldn't wait for a better season.
ENERGY STAR doors can earn $100 per opening through Ontario's Home Renovation Savings Program.
Most people plan this backwards. They pick an install month, then start shopping. With a built-to-order door, you work back from the day you want it on the house — and that usually means ordering a season earlier than you think.
What is the best month to replace a front door in Ontario?
September and October are the best months to replace a front door in Ontario, with May and June a close second. Daytime temperatures sit comfortably above freezing, humidity is lower than midsummer, and there's rarely snow or ice at the threshold.
Temperature matters more than most homeowners realise. Standard low-expansion window and door foam is rated for roughly 4°C to 38°C, and exterior sealants bond best in the same range. Install on a mild day and everything around the frame cures the way the manufacturer intended.
Fall has one more advantage. You fix the draft right before the heating bills start.
Season | Typical conditions | Why it works | Watch out for |
|---|---|---|---|
Spring (Apr–Jun) | 5–22°C, rainy spells | Mild for curing; good light for colour decisions | April rain delays; busy schedules by June |
Summer (Jul–Aug) | 20–30°C, humid | No cold exposure at all | Peak demand; heat and humidity slow stain and paint drying |
Fall (Sep–Nov) | 5–20°C, drier | Best curing conditions; solves drafts before winter | Order by late summer if you want it before the first freeze |
Winter (Dec–Mar) | -15 to 0°C | Shorter waits; immediate heating savings | Needs cold-rated products and a calm, milder day |
Can you replace a front door in winter in Ontario?
Yes, you can replace a front door in winter in Ontario, as long as the installer plans for the cold. The old door comes out and the new pre-hung unit is set, insulated and sealed in the same visit, so the opening isn't left exposed overnight.
The details are what separate a good winter install from a callback. Crews switch to cold-weather foam and temperature-rated sealants, and they keep materials warm until the moment they're used. Below about -10°C, some sealants simply won't bond, so a smart installer picks a calmer, milder day rather than the worst week of January.
And there's a real upside. According to Natural Resources Canada, windows, doors and skylights can account for up to 35% of a house's total heat loss. A door that whistles in December costs you money every day you wait.
How far ahead should you order a custom front door?
Order a custom front door at least 6–8 weeks before you want it installed. At Door Gallery, production takes 4–6 weeks at our Concord facility, after a free in-home consultation where we measure the opening and settle finish, glass and hardware.
So the timeline looks like this: consultation and measure, design sign-off, 4–6 weeks of manufacturing, then a single installation visit. Want a new door before the holidays or the first hard freeze? Start the conversation in late summer.
This is the part big-box timelines hide. A stock door is fast because it's already built — for a standard opening. A door made for your opening, with your arch, your sidelites and your glass, needs shop time. We think it's worth it, but plan for it.
Built to order: a modern entry system with sidelites, assembled in the shop before install day.
When should you replace a front door right away, whatever the season?
Replace a front door immediately if it no longer keeps weather or intruders out. Timing advice only applies to doors that are tired, not failing.
You can see daylight around the slab or under the sweep.
Frost or ice forms on the inside of the door or frame in winter.
The sill or bottom of the frame is soft — a sign of rot that spreads into the subfloor.
The lock won't latch without lifting or shoving the door.
The glass is cracked or the insulated unit has fogged between the panes.
There's forced-entry damage to the frame or strike plate.
If a steel door is rusting through at the bottom edge, that's a common Ontario story — we explain why in our fiberglass vs steel comparison.
Does the time of year change what a new front door costs?
The season doesn't change the price of the door itself much — materials and labour cost roughly the same in February as in June. What changes is scheduling: slower months mean shorter waits and more flexibility on install dates.
Door Gallery custom doors start from $3,000 installed. For a full breakdown by material and configuration, see how much a front door costs in Ontario.
Rebates are the timing factor that can move the number. Ontario's Home Renovation Savings Program offers $100 per rough opening for ENERGY STAR certified doors and windows, but it requires a home energy assessment and at least two qualifying upgrades. The federal Canada Greener Homes Grant is closed, so don't budget around it.
What happens on installation day?
A standard single-door replacement takes one visit. Here's what a proper install looks like:
Floors and entry are protected.
The old slab and frame come out, down to the rough opening.
The opening and sill are checked for rot and levelled or repaired.
The new pre-hung unit is set plumb, level and square.
The gap is insulated with low-expansion foam — never high-expansion, which can bow the frame.
Interior trim, exterior capping and sealant go on.
Hardware, strike and weatherstripping are adjusted until the door closes with one finger.
Arched openings, double doors and new sidelites take longer, especially when brick or stone has to be reworked. Our own crew does every install — no subcontractors — and every door is backed by a 15-year warranty.
An arched entry with sidelites, fitted into the home's existing brick opening.

Frequently Asked Questions
Is fall or spring better for replacing a front door?
Fall is slightly better in Ontario. Temperatures in September and October are ideal for foam and sealants, the air is drier than spring, and you fix drafts right before heating season. Spring works just as well technically, but April rain can push dates and schedules fill quickly by June.
How cold is too cold to install a front door?
There's no hard cut-off, but below roughly -10°C some sealants won't bond properly. Experienced installers use cold-rated foam and sealants, keep materials warm, and choose a calmer, milder day. If a deep cold snap is forecast, moving the date by a few days is the smart call.
How long does it take to install a front door?
A single front door replacement is usually completed in one visit. Double doors, sidelites, transoms or arched openings take longer, especially if masonry has to be adjusted. For custom doors, the longer part is production: Door Gallery doors take 4–6 weeks to build before install day.
Will my house be open to the cold during a winter install?
Only briefly. The old door is removed and the new pre-hung unit is set in the same visit, so the opening is never left overnight. Installers work in stages and keep the house as closed up as possible. You'll feel some cold air near the entry, not throughout the house.
Do I need a permit to replace a front door in Ontario?
A like-for-like replacement in the same opening typically doesn't need a building permit. Widening the opening, adding sidelites that change the framing, or altering a load-bearing wall usually does. Rules vary by municipality, so check with your city's building department before any structural change.
How much notice do I need for a custom front door?
Plan on 6–8 weeks from your first consultation to installation. That covers measuring, design approval and 4–6 weeks of manufacturing. If you want the door in before the holidays or the first hard freeze, start the process in late summer or early fall.
