Why the Efficiency Maine Program is a Must

The benefits of the Efficiency Maine Program extend beyond just financial savings; they include living in a more comfortable, energy-efficient home, contributing to environmental conservation, and enhancing the value of your mobile home.

Mobile Home Insulation Cost: Common Questions

Insulating underneath a mobile home — the underbelly — typically runs $2,500 to $6,000 in Maine depending on the size of the home, how much of the existing belly board and insulation has to be removed, and whether rodent damage or moisture has to be addressed first. Efficiency Maine rebates cover 40–80% of qualifying project costs, so most homeowners pay far less out of pocket.

Replacing the underbelly (belly wrap) on a mobile home generally costs $1,500 to $4,000 installed, depending on the home's length and how much of the old material and wet insulation needs removal. Replacement is often bundled with new underfloor insulation, since the belly has to be opened up either way — doing both at once is cheaper than doing them separately.

A new vapor barrier under a mobile home typically costs $800 to $2,200 depending on square footage and site access. In Maine's climate a properly sealed vapor barrier is essential — without it, ground moisture drives up into the floor system and causes the mold, soft floors, and cold rooms we're most often called in to fix.

Yes. Mobile and manufactured homes qualify for Efficiency Maine insulation and air sealing rebates. Any-income households can receive up to 40% of project cost, moderate-income up to 60%, and low-income up to 80% (capped at $8,000). Mattra is a registered Efficiency Maine vendor and handles the paperwork for you. See our Efficiency Maine rebate guide for details.

In most cases yes, especially in Maine. Older mobile homes typically have thin, compressed, or moisture-damaged underfloor insulation, so heating costs are high and floors stay cold. Because rebates cover 40–80% of the work, the payback period is usually short — and fixing the moisture side at the same time prevents the mold and floor rot that cost far more to repair later.
