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 you’ll get the money back. The data on this is unusually clear: exterior projects return more at sale than almost any interior renovation, and a few of them return more than they cost. Here’s what the numbers say, adjusted for how Ontario buyers actually behave.
What the Cost vs. Value Data Shows
The most cited source is the annual Cost vs. Value Report, which surveys real estate professionals on what a project adds to sale price versus what it costs. It’s U.S. data, so treat the exact percentages as directional for Ontario, but the ranking has been consistent for years. The 2025 edition’s exterior results:
| Project | Cost recouped at sale (2025 report) |
|---|---|
| Garage door replacement | About 270% |
| Steel entry door replacement | About 215% |
| Fibre cement siding replacement | About 115% |
| Vinyl siding replacement | About 95% |
| Vinyl window replacement | About 90 to 95% |
| Wood window replacement | About 90% |
| Typical mid-range kitchen remodel | About 70 to 80% |
| Typical bathroom remodel | About 65 to 75% |
Two projects, the garage door and the entry door, returned more than double their cost. Siding and windows returned close to full cost. That’s a better result than nearly every interior project.
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 return close to their cost, which means they’re roughly break-even at sale and then you’ve had the energy savings and comfort in the meantime. Where they matter most for resale is when the existing windows are visibly failed: fogged glass, rotted frames, or painted-shut sashes. Buyers and home inspectors flag those, and the negotiated deduction is often larger than the replacement would have cost. Replacing a few failed windows is a better resale move than replacing all of them for the sake of it; replacing everything with black windows on the front elevation is a strong move on a modern or brick 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.
