Battling the Draft: The Case for Insulating Your Mobile Home


Imagine stepping into your mobile home to escape the cold, only to find that the draft follows you inside. Different rooms have a different feel, and the heating bill brings a new chill of its own. You're aware that insulation can help, yet the upfront cost is too much. The promise of a lower electric bill is great, but the immediate cost is too much. If you find yourself feeling this way, know that options and assistance are available, especially if you reside in Maine.

Insulation Costs Across the Board: A Detailed Guide

For mobile homeowners outside of Maine, the costs of insulation depends of a few things. What are the specific areas requiring insulation, the materials selected for the job, the mobile home's size, and the prevailing labor costs in your locality? Below, we look at potential costs, breaking them down by area and highlighting key considerations. Please note, these are just examples. Actual costs will vary by location, material costs, and labor cost.


Roof/Ceiling Insulation: $1,500 - $3,000

  • Importance: The roof is a critical area for heat loss and gain. Proper insulation here can significantly impact your home's overall energy efficiency.
  • Materials: Options vary from traditional insulation to spray foam, each offering different insulation levels (measured in R-values) and price points.
  • Labor Considerations: The complexity of your roof's structure may influence installation costs.


Underbelly Insulation: $1,000 - $2,000

  • Significance: Insulating the underbelly helps in preventing cold floors and protecting pipes from freezing.
  • Material Choices: Rigid foam, spray foam, and traditional insulation are common selections, with each material suited to different needs and budgets.
  • Installation Challenges: Accessibility and the need for vapor barriers can affect the cost.


Wall Insulation: $2,500 - $4,000

  • Critical Factors: Walls are key to preventing heat from escaping. Adequate insulation can also reduce noise from outside.
  • Options: From blown-in cellulose to spray foam, the choice of material will depend on your insulation goals and wall structure.
  • Labor and Installation: The method of insulation (e.g., drilling for blown-in insulation) and the home's layout can influence the price.


Windows and Doors Upgrade for Better Insulation: $1,000 - $5,000

  • Efficiency Impact: Drafty windows and doors can undermine your insulation efforts. Upgrading can seal leaks and improve thermal performance.
  • Upgrade Options: Energy-efficient windows and doors come in various styles and efficiency ratings, affecting their cost.

Considerations and Tips

  • Prioritizing Areas: Focus on areas with the most significant heat loss first, typically the roof and walls.
  • Material Selection: Higher R-value materials offer better insulation but at a higher cost. Balance your budget with your energy savings goals.
  • Labor Costs: Obtain multiple quotes to ensure you're getting competitive rates for your area.
  • Long-term Savings: While the upfront cost is an important consideration, also evaluate the potential energy savings over time. Efficient insulation can reduce heating and cooling bills significantly, offering substantial savings in the long run.


While these cost ranges serve as a general guide, the specific expenses for insulating your mobile home will depend on individual circumstances. Careful planning and consideration of the factors mentioned above will help you make informed decisions that meet your needs and budget.


Why the Efficiency Maine Program is a Must

For Maine residents, the Efficiency Maine Program not only offers financial assistance but also peace of mind. Understand that the program operates on a fixed budget, which means once the allocated funds are depleted, the assistance is no longer available.


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.

Maine Attic Nightmares: Condensation, Mold, and Protecting Your Home

By Mattra Inc • August 18, 2025
That musty smell. The faint water stains on your attic ceiling. Maybe you’ve even spotted some unwelcome dark spots. If you’re a Maine homeowner, especially in our older homes, these could be signs of a serious problem brewing in your attic: condensation leading to mold growth. It's a more common issue than you might think, and it can have significant consequences for your home’s health and your wallet. Why is your Maine attic suddenly feeling like a rainforest? The culprit is often a perfect storm of factors we see frequently here at Mattra: a lack of proper air sealing and insufficient insulation. Think of your warm, humid indoor air rising into the colder attic space. Without proper air barriers, this warm, moisture-laden air sneaks through cracks and openings around wiring, plumbing, and light fixtures. Once this warm, moist air hits the cold surfaces in your uninsulated attic – like the roof sheathing – it cools rapidly. Just like water beading on a cold glass on a summer day, this cooling air releases its excess moisture in the form of condensation. And in a Maine winter, those surfaces stay cold for a long time! Several other common issues exacerbate this problem. That uninsulated attic hatch? It’s a direct pathway for warm, humid air to escape. An uninsulated chimney acts as another cold surface where condensation can form. And those bathroom and dryer vents that aren’t properly ducted to the outside? They’re pumping even more moisture directly into your attic – a recipe for disaster. So, what happens when all this condensation builds up? That’s where mold enters the picture. Mold spores are everywhere, both indoors and out. They thrive in damp, dark environments with organic materials to feed on – like the wood in your attic. Consistent condensation provides the perfect breeding ground. As mold grows, it doesn't just create unsightly stains and that telltale musty odor. It actively deteriorates the materials it grows on. Over time, mold can weaken the structural integrity of your roof sheathing and rafters, leading to costly repairs. It can also damage any stored items in your attic. Beyond the structural damage, mold growth can also impact your indoor air quality. Mold spores can become airborne and circulate throughout your home, potentially triggering allergic reactions, asthma symptoms, and other respiratory issues for you and your family. As a licensed vendor with Efficiency Maine , we understand the importance of a healthy home environment. The good news? These attic issues are often fixable! Proper air sealing prevents that warm, humid air from entering the attic in the first place. Adequate insulation helps maintain a more consistent temperature in the attic, reducing those cold surfaces where condensation forms. Insulating the attic hatch and chimney are crucial details often overlooked. And ensuring your bathroom and dryer vents are correctly ducted to the exterior is essential for removing excess moisture from your home. Addressing attic condensation and mold growth is an investment in your home's long-term health and your family's well-being. If you suspect you have an issue in your Maine attic, don't wait for the problem to worsen. Contact the experts at Mattra right here in Lewiston. We can assess your attic, identify the sources of condensation, and recommend the best solutions for mold remediation and preventing future problems through proper air sealing and insulation. Protecting your Maine home starts from the top down!

Blower Door Test

By Mattra Inc • April 3, 2025
Is Your Home Under-Insulated and Leaky? A Blower Door Test Can Tell You Many Maine homeowners don’t realize just how much money is flying out the window—literally. Drafty rooms, cold floors, and rising energy bills are often signs of poor insulation and hidden air leaks. But how do you know where your home is losing heat? A blower door test is one of the most effective tools to identify under-insulated and under-sealed areas in your home. Let’s explore how it works, why it matters, and what steps you can take to improve your home’s energy efficiency—and unlock valuable Efficiency Maine rebates in the process. What Is a Blower Door Test? A blower door test uses a powerful fan, mounted into an exterior doorway, to pull air out of your home and lower the indoor air pressure. This forces outside air in through any cracks or gaps in the building envelope. The result? A clear picture of where your home is leaking air. This test measures air changes per hour (ACH) and identifies weak points in insulation and air sealing. It helps assess how well your home keeps conditioned air in—and the outdoor elements out. An experienced technician can use this data to recommend targeted upgrades, saving you money on heating and cooling costs. How to Pass a Blower Door Test: Key Air Sealing Tips Passing a blower door test doesn’t require a full renovation—it’s about sealing the right places effectively. Here are the most common areas to focus on: 🪟 Windows and Doors Install weather stripping Use caulk or foam sealant around frames Check for gaps in thresholds or broken seals 🧱 Attics and Ceilings Seal around light fixtures and access hatches Insulate attic floors and rafters Use foam board or spray foam in hard-to-reach corners 🧰 Basements and Crawlspaces Seal rim joists with spray foam Insulate basement walls and floors Cover and seal crawlspace vents and doors 🧹 Floors and Walls Fill gaps around pipes, wiring, and ducts Seal baseboards and floor edges Add insulation in wall cavities if accessible By addressing these common problem areas, you can drastically improve your blower door test results and the overall comfort of your home. Why Blower Door Testing Matters Blower door tests aren’t just for code compliance—they’re a diagnostic tool to understand your home's efficiency. When performed by professionals, these tests: Reveal hidden air leaks Provide data for insulation and air sealing improvements Help reduce energy bills Improve indoor comfort and air quality Support home energy audit documentation During the test, technicians record the building's air leakage rate using calibrated gauges. Smoke pencils or infrared cameras may also be used to visualize the leaks. This ensures your energy upgrade dollars go exactly where they’re needed most.
