Although specifics of the contract differ between window manufacturers in Canada, there are numerous golden rules to look for in any potential agreement between you and the windows and doors company. We’ll show you what they are to make sure you know exactly what you are getting with your window replacement.

Because part of a supplier’s job is to come to your house to sell windows, they are also often in the business of installing them. Such type of work requires a “supply and install” contract. The advantage in this situation is that there is only one company accountable for your contract.

What to look for in a replacement window contract?

  • The most important rule is often the most overlooked: always have the contract signed by both parties before any work on your house begins.
  • A contract needs to have the date by which the job is to be completed.
  • The contract should include the full cost of the work, and give a specific description of all the windows.
  • The contract should list all the window and door products and their configuration that will be used during the installation.

What to do when your window order arrives?

You can save a lot of money and time by making sure the windows that get delivered are the same as specified in the contract. Double check the style, size, and certification labels on all the windows. Make sure that the invisible features in the windows (low-E coating, spacers, gas fill) have appropriate labels on the unit. In a “supply and install” arrangement the manufacturer is usually responsible for the product quality, and the supplier for the quality of the installation.
