You’re tired of dealing with high monthly energy bills and an uncomfortable house, and you’re considering spray foam insulation, but you need to plan a budget.

The cost to insulate your mobile home with foam insulation will vary depending on several factors, from the size of the house to the size of the areas to be insulated.

RetroFoam of Michigan has insulated thousands of homes across Michigan’s Lower Peninsula and the greater Toledo area. We have experienced crews that are specially trained to inject and spray foam in your home, ensuring it is an energy-efficient and comfortable space for you and your family.

Because every mobile home isn’t created equal, the prices we give in this article are a range. The best way to get an exact quote is to have one of our project managers out to your home to provide you with a free, no-pressure quote.

How Much Does it Cost to Insulate a Mobile Home with Foam Insulation?

The cost to insulate your mobile home will depend on the area's square footage.

The price range to insulate a single mobile home from top to bottom is between $5,000 to $7,000. This covers the ceiling, walls, and skirting.

What Factors Determine the Total Cost of Spray Foam Insulation?

The number one thing that determines the cost of foam insulation is the size of the area to be insulated.

A single mobile home is going to be smaller and less expensive in comparison to a double.

Another factor is the type of foam used for your project. In the areas where spray foam is used, the choice between open cell and closed cell spray foam can make a difference in the price. This is because closed cell spray foam tends to be more expensive than open cell.

Foam Insulation Installation Process

Insulating your mobile home can take one to two days, depending on if there is old insulation that needs to be removed around the skirting, ceiling, or rim joist.

Let’s start at the top and work our way down to the bottom.

Installing Foam Insulation into the Ceiling of a Mobile Home

The ceiling in your mobile home can be insulated on a case-by-case basis.

This is because some mobile homes only have paneling for a ceiling, which isn’t strong enough to hold up the foam. If you have a solid ceiling with drywall, then the foam can be sprayed into the ceiling.

Before the installation, crews will remove any old insulation in the ceiling so the spray foam has a clean surface to adhere to.

To insulate a drywall ceiling, strips are cut into the ceiling, and the foam is sprayed into each cavity. Once the foam has been injected, crews will replace the drywall and use a rough patch of mud around the seams. It is up to the homeowner to finish the sanding and any painting that needs to be done.

If the mobile home has a drop ceiling, those panels can be removed so the foam can be sprayed. Once the insulation is installed, the panels will be replaced.

Installing Foam Insulation into the Walls of a Mobile Home

Insulating the walls can vary depending on the type of siding you have on your mobile home.

It may not seem like it, but the direction your siding was installed can play a big part.

Usually, the siding of a home is installed horizontally, but there are cases where it is installed vertically. If your mobile home has vertical aluminum siding, the process is different than if it was horizontal.

Vertically installed siding is not really meant to be removed, so in this case, our crews would drill a small hole around 1 ½-inches into the siding to inject the foam. After the foam has been injected into the stud cavities all around the home, the holes are then plugged and sealed with caulk.

Crews take their time with this process so as not to dent the aluminum siding.

Now let’s look at the process for insulating walls with horizontal siding, wood, and brick.

The process for aluminum and vinyl siding is similar. A strip of siding is removed, and holes are drilled between the stud cavities. After injecting the foam insulation, the crews will plug up the hole, put the siding back on, and clean up any excess foam.

Wood siding is handled differently. Depending on the condition and make of your wood siding, we may be able to remove it and follow the same process as vinyl or aluminum siding. If the wood siding can’t be removed, the crew will drill through it to inject the foam and then plug the hole with a tapered wood plug.

The brick exterior can also be insulated without removing any of your bricks. Installers drill a 5/8-inch hole through the mortar joints to inject the foam insulation. The holes are then re-mortared once the installation is complete. 

Installing Spray Foam Insulation on the Mobile Home Skirting

Now for the skirting and rim joist.

When insulating under your mobile home, we first remove any old insulation underneath. The installation crew will then spray the skirting. We do this because the underside of the floor usually has mechanicals that are running. We treat underneath the mobile home like a crawl space and insulate the “walls,” which is the skirting.

This method seals out the air from the outside, helping to keep your home comfortable and reducing monthly energy bills. Another benefit of this method is it will make the space less attractive to pests.

Types of Foam Insulation Materials Offered

When an entire mobile home is insulated with foam insulation, the crews will use spray foam and injection foam.

It comes down to the areas that need to be insulated and whether the cavities are open or enclosed.

Injection foam will be used in the enclosed walls, while spray foam will be used in the rim joist, ceiling, and around the skirting.

What Other Services Are Offered When Insulating Your Mobile Home?

  • A free estimate with no pressure sales tactics.
  • Free concierge program that leaves the homeowner with a go-to person to answer all of their questions from start to finish.
  • Help to complete financing for the homeowner. It will be important to discuss this with your insulation contractor because some lenders don't offer loans because the land is leased. There are lenders who do have loan options in this scenario.
  • Preparation before installation includes removing old insulation and covering items in the home to keep them clean and protected.
  • Cleanup after installation so the mobile home looks just like it did before the work began.
  • Filling out rebate paperwork with the homeowner's energy provider.
  •  A lifetime warranty that covers workmanship as well as materials. This lifetime warranty lasts as long as the home does and is transferable if the house is sold.

How Long Does it Take to Insulate an Entire Mobile Home?

In most cases, an entire mobile home can be insulated in just one day.

The day of the installation is spent removing any old insulation underneath the mobile home. Then, the foam insulation is installed.

Removal of old insulation, spraying, and injecting foam insulation can range anywhere between 3 to 5 hours.

Additional Fees, Taxes, and Costs

There are no additional fees or hidden costs once your project has been completed. The quote you sign and agree to is the final cost to insulate your mobile home.

Unlocking Savings: Foam Insulation Rebates and Tax Credits for Michigan Homeowners

Let's first clarify the distinction between rebates and tax credits.

Rebates are like cash rewards given to homeowners who accomplish specific energy-efficient upgrades.

On the other hand, tax credits directly reduce your tax liability when you invest in energy-efficient home improvements.

Michigan homeowners can choose from several types of rebates and tax credits.

The standard mail-in insulation rebate caters to those insulating a single area of their homes, with rebates ranging from $50 to $250, depending on the project's size. Utility providers like Consumers Energy, DTE, SEMCO, and Michigan Gas and Utilities are your go-to sources for these rebates. If you're insulating at least two areas of your home, you may qualify for the home performance rebate, which ranges from $400 to $1,100.

The Inflation Reduction Act, a policy supporting energy-efficient home improvements, offers a tax credit of up to $1,200 annually for individual insulation or other energy-efficient upgrades.

This tax credit is available until 2032. Moreover, homeowners can claim an additional credit of up to $150 for home energy audits. To access this tax credit, you'll need to complete IRS Form 5695 and include a copy of your contract with RetroFoam of Michigan.

It's essential to note that eligibility for these rebates and tax credits may require consultation with your energy provider and a tax professional to ensure your work qualifies.
