Most of these programs follow a similar structure: roughly one year of coverage on materials and labour, two years on major systems like electrical, plumbing and heating, and a longer structural period, often 5 to 10 years, on the building envelope itself.
The gap buyers miss most is timing. Warranty coverage typically starts on possession, not on the purchase agreement date, and claims usually have to be filed within specific windows after that, so a delayed possession can quietly shrink the time you actually have to report a problem.
Joel Dyck reviews the warranty documentation on new-construction purchases and resales alike, since a resold new-build can still be inside its original coverage period. Get your hand-reviewed valuation from Joel Dyck.
