If you’re selling in the next year or two, the question isn’t whether an exterior upgrade is nice to have; it’s whether it will help the sale. Some U.S. resale data shows strong returns for exterior projects, but no report can predict a particular Ontario sale price. Here’s how to use the data without overpromising.
What the Cost vs. Value Data Shows
The most cited source is the annual Cost vs. Value Report, which combines U.S. real-estate-professional surveys with national cost data. It is not Ontario data, so use the percentages as directional context only—not as a promised return. The 2025 national figures published by the report include:
| Project | Cost recouped at sale (2025 report) |
|---|---|
| Garage door replacement | 267.7% |
| Steel entry door replacement | 216.4% |
| Fibre-cement siding replacement | 113.7% |
| Minor kitchen remodel | 112.9% |
| Vinyl siding replacement | 96.5% |
In that U.S. report, garage-door and steel-entry-door replacements returned more than double their cost. The report does not establish a comparable Ontario return for a specific window project, so treat windows as a condition, comfort, and curb-appeal decision rather than a guaranteed investment.
Why Exterior Beats Interior
Buyers decide a lot in the first ten seconds on the sidewalk and the first ten seconds online. A fresh exterior signals a maintained house and lets the listing photos do their job. Interior tastes vary, so a kitchen renovation may not suit the buyer, but nobody objects to a new front door. And exterior projects are relatively cheap in absolute terms: a $2,500 door moves the perception of a $900,000 house.
Garage Door
On a typical Ontario two-storey, the garage door is a third of the front elevation. Replacing a dented beige builder door with a carriage-style or modern flush door in black or a wood tone, matched to the front door, transforms the house for $2,500 to $5,000. It’s the highest-return item on the list and the one most sellers overlook.
Entry Door
The entry door is the handshake. A new steel or fibreglass door with sidelites, in a colour that suits the brick, costs $2,000 to $5,000 in Ontario and reliably photographs well. Our colour guide and material guide will help you pick.
Siding
Siding is the biggest ticket and the biggest visual change. Faded, dented, or mismatched siding is a red flag to buyers and inspectors; new siding removes it. Fibre cement returns slightly more than vinyl in the data, partly because buyers recognize the brand and partly because it photographs like painted wood. On a partial-siding Ontario home (brick below, siding above), re-siding the upper storeys and gables is a moderate cost with a large effect.
Windows
Windows are most persuasive at resale when the existing units are visibly failed: fogged glass, rotted frames, or painted-shut sashes. Replacing a few failed windows may make more sense than replacing every unit solely for a listing; weigh the cost against the home’s condition, neighbourhood, and listing strategy with your agent. New windows also bring comfort and energy-performance benefits while you still live in the home.
Ontario-Specific Factors
- Energy costs matter to Ontario buyers. ENERGY STAR® windows and doors, listed in the feature sheet, are a real selling point in a province with cold winters and rising energy prices.
- Transferable warranties on windows, doors, and siding can be mentioned in the listing. Keep the paperwork.
- Heritage districts reward period-appropriate work and penalize the wrong vinyl; see our century home guide.
- Timing: lead times of 5 to 10 weeks mean exterior work for a spring listing should be signed in winter.
- Permits: any unpermitted structural work (enlarged openings, egress cuts) surfaces in a sale. Do it properly.
If You Can Only Do One or Two
- Replace anything broken or failed: fogged windows, a rusted door, missing siding. Removing red flags returns the most.
- Garage door and front door, in coordinated colours. Biggest visual change per dollar.
- Front-elevation siding or windows if the street view still lets the house down.
- Whole-house windows only if they’re near the end of their life anyway, and preferably a year or two before selling so you get the comfort too.
