Although the manufacturer is the one who will be doing the installation every manufacturer is required by federal standards to provide instructions for installation. The installation of your manufactured home is not covered by the manufacturer's warranty but by the person responsible for the installation itself. Thousands of manufactured homes are installed on sites every year without problems. You should not have problems if your home is installed by a reliable retailer or by a company that specializes in manufactured home installation. Installation is every bit as important as buying the home itself.
Improper setup can significantly reduce the life of even the best constructed home.
Check for damage as soon as you receive your home and report any problems to the manufactured home dealer or transporter as soon as possible by letter, keeping a copy for yourself. If any damage has been done during transport, it should be fixed before or during setup but you need to make sure it is. You will also need to do an inspection after the home is setup and another after the home has time to settle in. The manufacturer's written warranty on the home usually will not cover problems that are caused by improper installation. In most cases, the price of your home will include the cost of installation.
