Understanding what warranties apply to your renovation is important — especially when things go wrong months or years after completion. Here’s the 2026 guide.
New homes vs. renovation — a critical distinction:
Ontario’s New Home Warranties Plan Act (NHWPA) provides mandatory warranty coverage for new homes: 1 year on materials and labour, 2 years on building envelope, 7 years on major structural defects. This does NOT apply to renovations. Renovation warranties are contractual — what’s in your contract is what you have.
What to negotiate into your renovation contract:
- 1-year labour warranty: Contractor will repair defects in workmanship for 1 year after completion. This is industry standard.
- Manufacturer warranties passed through: Materials typically have manufacturer warranties (tile, flooring, cabinetry, appliances). Get these documentation passed to you.
- Specific extended warranties where applicable: Waterproofing systems typically come with 10–25 year warranties from the manufacturer — get these in writing.
What the warranty doesn’t cover:
- Normal wear and tear
- Damage caused by homeowner misuse
- Changes made by the homeowner after completion
- Issues that existed before renovation (be specific in your contract about what was pre-existing)
When warranty claims are denied:
Document everything from day one. Photos before, during, and after. Email correspondence for all change orders and approvals. Without documentation, warranty disputes become ‘he said / she said’ situations that are difficult to resolve.
The 45-day lien period:
This is not a warranty provision — it’s the Construction Act holdback period. But it coincides with the period when early deficiencies often appear. Use the holdback strategically.
