When soffit and fascia actually need replacing
Soffit and fascia rarely fail all at once. Usually you notice one corner pulling away from the house, paint bubbling on the wood trim underneath, or wasps finding their way in through a gap. Left alone, water gets behind the fascia, the wood rots, and what was a simple swap becomes a carpentry job first.
Signs it’s time to look at replacement:
- Peeling paint or moisture damage on the fascia boards
- Sagging or loose soffit panels
- Visible gaps or holes (common pest entry points)
- Poor attic ventilation or ice damming showing up in winter
- Soft or rotting wood behind existing aluminum capping
If the underlying wood fascia is solid, aluminum replacement is typically a single-day job on most detached homes. If the wood has rotted through, budget for a carpentry phase before the aluminum goes on.
What it costs in Ontario (2026)
Pricing runs roughly $8-$14 per linear foot for soffit and $6-$12 per linear foot for fascia, installed (labour, materials, removal, disposal). For an average GTA detached home with about 180 linear feet, that puts the total between $2,500 and $4,700 depending on profile complexity, access, and the condition of the underlying framing.
GTA pricing is 10-15% higher than the provincial average, mostly labour rates and access costs on tighter urban lots.
Things that push the number up:
- Two-storey work (staging or lift equipment adds time)
- Rotted wood fascia that needs replacing before the aluminum goes on
- Custom profile matching on older or heritage homes
- Adding eavestrough replacement to the scope (eavestroughs come down regardless during a fascia job)
On that last point: if your eavestroughs are close to end of life anyway, combining all three – soffit, fascia, eavestrough – in one mobilization saves roughly 10-15% versus three separate visits. The crew is already set up either way.
Aluminum vs. vinyl vs. wood
Aluminum has dominated Ontario installations for good reason. It doesn’t rot, handles freeze-thaw without cracking, and the perforated soffit panels provide continuous attic ventilation without retrofit work. Vinyl costs less upfront but goes brittle in hard winters and expands noticeably in summer heat. Wood looks appropriate on some older homes but needs ongoing paint maintenance, which most homeowners eventually stop doing.
For most GTA houses replacing aging steel or wood trim, aluminum is the clear choice.
What the job involves
A crew will remove the eavestroughs first (or set them aside if they’re staying), strip off the old soffit panels and fascia capping, then check the underlying wood framing for rot or moisture damage before anything new goes on. If repairs are needed, that happens before the aluminum. Then it’s fascia capping, J-channel, soffit panels, and reinstalling or replacing the eavestroughs. Any penetrations get sealed at the end.
On a single-storey home with no rot, two people finish in a day. Two-storey homes with complex rooflines run two to three days.
Questions to ask before signing
- Who holds the permit if one is required? Not all soffit and fascia work triggers a permit, but any structural repairs underneath it do.
- What gauge aluminum are you using? Heavier gauge holds shape better across longer spans. On fascia, .019 or heavier is worth asking for.
- Do you inspect the wood before quoting, or after you start? A contractor who includes that inspection upfront is less likely to hit you with rot-related change orders mid-job.
- What’s the warranty on materials versus workmanship? Aluminum products often carry 30-year manufacturer warranties. The installer’s labour warranty is a separate question.
Getting answers to these in writing before the job starts avoids most of the friction that comes up once work is underway.
