The first step is to follow our statutory warranty process

Every builder is required by law to provide limited warranty coverage to new home buyers. It is important that purchasers take the time to understand the details of this warranty and how to use it.
Tarion is responsible for ensuring that builders repair or resolve items that are covered by the statutory warranty based on a minimum customer service standard. We can help resolve disputes about what is and is not covered, but homeowners must follow a statutory warranty process to request our involvement.
Please note: Your builder may choose to provide workmanship and materials or coverage beyond what is required by law, however these warranties would not be subject to Tarion’s oversight.
