Finding a Contractor for Mobile Home Insulation

Look for manufactured-home experience specifically

Plenty of insulation contractors work primarily on site-built houses with full basements, deep wall cavities, and open attic access. A mobile home's belly cavity, narrow wall framing, and (on double-wides) marriage line call for different access methods and materials — dense-pack drill-and-fill technique, belly board repair, and duct sealing inside a confined crawl-height space. When you're screening a contractor, it's worth asking directly whether manufactured and mobile home retrofits are a regular part of their work, not an occasional exception.

It's also worth confirming Efficiency Maine Registered Vendor status specifically — that's what makes a project eligible for the rebate programs described on the previous page, and a registered vendor will typically handle the rebate paperwork as part of the job.

Questions worth asking before you sign

• Are you an Efficiency Maine Registered Vendor, and will you handle the rebate paperwork?
• Do you regularly work on single-wide or double-wide mobile homes, and can I see recent examples?
• Will you perform a blower door test before and after the work to document the improvement?
• How do you handle a damaged or sagging belly board — is repair included in the scope, or priced separately?
• What R-value and material will be used in the attic, walls, and belly, and how will installed depth be verified?
• If this is a double-wide, how will the marriage line be sealed and insulated?
• Are you BPI-certified or equivalently trained, and are you insured?
• Can I get the quote itemized by zone (roof, walls, belly, marriage line) so I can see where the rebate applies?
