If you have a problem with your manufactured home that should be covered under your warranty:
Organize all your records and document your complaints. Make a record of all conversations with retailers, manufacturers, and state and federal agencies from this point on
Contact both your retailer and your manufacturer. Contact information should be in the homeowner’s manual or other documentation provided at the sale. If you contact a party by phone, be sure to follow up with written notifications to both your manufacturer and retailer. Address the letters to specific people with specific titles to create a clear paper trail. Include your name, contact information, and the label number of your home. The label number can be found on a red seal issued by HUD and affixed to all homes built under their jurisdiction.
Keep the letter brief and to the point. Include the date and place you made the purchase, who performed your installation, the serial or model number and warranty terms, what went wrong, and any actions you have taken to correct the problem.
Enclose copies of your records (store the originals in a safe place), including receipts, guarantees, warranties, canceled checks, contracts, and any other documentation.
Send the letters by certified mail. Some states will require this as proof of notice
If service personnel attempt to perform work, but do not complete repairs to your satisfaction, do not sign off on service orders that state the job has been completed.
