Is it under warranty? When you buy a Cook home you receive a one-year limited warranty with Cook Residential. When customers buy a Cook home, they receive a warranty book, which has their username and password for the warranty portal. Home buyers also receive a homeowner’s handbook and closing documents. If you have any issues with the home, it’s imperative that you log into the warranty portal and submit the claim. Even if it’s a claim for an outside vendor, like plumbing or electricity, we still ask that you submit a claim to the warranty portal. This is so we can stay on top of the claim as well, and make sure that your claim is at the top of that vendor’s list.
