Fall Door Replacement: How to Plan Custom Doors Before Winter

Fall is the last good window for fall door replacement in Toronto and the GTA. In 2026, autumn begins on September 22 and winter begins on December 21. A custom door is built after you order it, so the weeks between now and the first snow decide when your new door goes in, before the cold or after it.

We are EHI Custom Doors. We manufacture, supply and install custom fiberglass front doors and back doors from our workshop in Whitchurch-Stouffville. This guide shows the dates to work back from, the things that slow a door project down, and how to decide what to order.

Why Fall Is the Season to Plan a Custom Door

Fall is when a custom door order still fits inside the good weather. At EHI Custom Doors the standard lead time is 4 to 6 weeks from a confirmed order, and custom glass can add 1 to 2 weeks. An order confirmed in early October is ready in November. An order confirmed after the first snowfall is ready in December or January.

Toronto's average first frost arrives around the start of November, and snow often follows within weeks. Most homeowners notice a bad door on the first cold night, when the draft shows up. By then the lead time has already used up the weeks you had.

Fall also brings Thanksgiving, the holidays and visitors. The entrance is the first thing they see. A new door that is in before those weekends is a project you get to enjoy, not one you are still waiting for.

Your Fall 2026 Door Replacement Timeline

The lead time runs from the day your order is confirmed. Use this table to work backward from the date you want the door in. It assumes 4 to 6 weeks for a standard build and 5 to 8 weeks when custom glass adds 1 to 2 weeks.

What Causes Door Project Delays, and How to Avoid Them

• Waiting for the cold snap. Lead time does not get shorter when it turns cold. Order while the weather is still mild.
• Changing the design after approval. At EHI you approve the quote before manufacturing begins. A change after that point can restart the build, so settle the design first.
• Custom glass. Glass designs that are not readily available add 1 to 2 weeks. Choose glass early. Our guide to exterior door glass options helps you decide.
• Unclear measurements. Our installer confirms the opening at a final measurement visit before we build. Sending clear photos with your first quote request avoids surprises.
• Approvals. A heritage property or a changed opening needs City approval before you order. See the permit notes in our guide on custom doors vs stock doors.
• Install-day weather. A flexible schedule lets the installer pick a mild day.

Decisions to Make Before You Order

A door project moves fastest when the choices are made before the order is placed. Work through this list first:

1. Which doors: front, back, or both.
2. Single or double.
3. Sidelights and a transom, or neither.
4. Glass: clear, frosted, textured or decorative, and where it sits on the door.
5. Finish: oak grain, mahogany grain, smooth or contemporary, in wood tone or a solid colour.
6. Hardware finish: satin nickel, oil rubbed bronze or matte black.
7. Budget. Single doors start at $2,500 installed and double doors start at $5,100 installed, and our guide to custom exterior doors cost in Toronto shows what moves the price. We also offer 6-month no-interest financing through Financeit Canada.
8. Photos of each opening, inside and outside, to send with your quote request.

If you need ideas, the door catalogue and our gallery of installed doors show what other homeowners chose. Keep the styles and finishes you like on a shortlist before you call.

Which Doors to Replace First

Replace a door now, not in spring, if it shows any of these signs:

• A draft at the edges, or daylight visible around the door
• Frost or cold patches on the inside of the door or frame
• A door that sticks, will not latch, or looks warped
• A cracked or soft frame, or water stains at the sill
• Loose hardware, or a lock that no longer lines up

At that point replacement is the fix that lasts, and our guide on when to replace an exterior door has a 10-minute check and a repair vs replace test. If both doors are worn, start with the one that takes the most weather and the most daily use. Front doors face the street and greet your guests. Back doors take heavy traffic to the deck and yard. You can request a quote for both at once and choose matching finishes.

Fall Weather and Door Installation

Mild fall temperatures suit installation well. Sealants and foam cure properly, and the opening is exposed to the outdoors only briefly. Fiberglass also helps through the seasons. Wood swells in humid air and shrinks in dry air, so its fit changes through the year, while fiberglass resists warping, swelling and rot.

We install in every season, winter included. A winter install works when the installer uses sealants and foam rated for cold weather, picks a mild forecast day and keeps the opening exposed only as long as the work needs. Ask any installer how they handle it before you book.

Why Replace Before the Heating Season Starts

Natural Resources Canada says windows, doors and skylights together can account for up to 35 percent of a home's heat loss. It also says a poorly installed product can cause cold drafts even when the product itself is energy efficient. A tight-fitting door made for your opening, installed well, is the fix.

Doing it before the heating season means you feel the difference on the first cold night, not the fifth. If you want to compare a made-to-measure door with an off-the-shelf one first, our guide on custom doors vs stock doors covers sealing, ratings and what to ask.

Choosing a Door That Looks Right in Every Season

In Ontario a door is seen against green summer, orange autumn brick and white snow. Dark colours such as black, charcoal and espresso stand out sharply against snow. Oak and mahogany wood-grain finishes warm up brick and stone all year. Our fiberglass holds its colour and finish for years without repainting, so the look you choose in fall is the look you keep.

Glass changes how a door works in a short winter day. Sidelights and a transom bring in daylight when the sun sets before 5 pm. Our exterior door glass guide shows how to keep that light and still have privacy.

Should You Wait Until Spring?

What to Look for in a Custom Door Company

• Who builds the door. We manufacture every door in our own workshop, with no dealers in between.
• Who installs it. Our own team does, with no subcontractors, so one company answers for the whole job.
• A clear timeline in writing, including glass.
• A warranty you have read. Ours is a lifetime warranty on the fiberglass slab, frame and brickmould. Hardware, glass and installation are not covered unless stated separately.
• Proof from real customers. We are HomeStars Verified and a HomeStars Best of Award winner for 2021, and you can read customer feedback on our reviews page.
