In 2026, the national average cost to winterize a mobile home is $200. Most homeowners spend $100 to $500, with the final cost driven by the complexity of work needed, the age of your home, and your local climate.

Winterizing a Mobile Home Cost Factors: What Affects the Price?

Whether you plan to stay in your mobile home all winter or leave it vacant, you'll need to winterize it to keep it in good working condition. The total cost depends on several variables, including the type of project, your location, the size of your home, and the age of the mobile home.

Cost by Type of Project

Here’s a look at the average cost of some common mobile home winterization projects.

• Change Furnace Filters: $5 to $100

• Furnace Inspection: $80 to $100

• Add Skirting Around the Base: $300 to $3,000

• Insulate Windows and Doors: $3 to $20 per sq. ft.

• Insulate Pipes: $1.10 to $11 per linear ft.

• Exterior Caulking: $25 to $50

• Install Storm Windows: $55 per sq. ft.

• Roof Inspection: $125 to $343

• Roof Insulation: $0.50 to $3.50 per sq. ft.

• Clean Gutters: $119 to $228

• Repair Water Leaks Under the Home: $500

• Empty Garden Hoses: $56 to $131

Change Furnace Filters

You can expect to pay between $5 and $100 to replace your furnace filters. Your overall cost will depend on how often you need to change the filter and the type, with HEPA filters costing much more than standard flat filters. 

Furnace Inspection

You’ll pay between $80 and $100 to have an HVAC company near you inspect your furnace. Having your furnace inspected is critical. A pro will replace the exhaust vents, replace worn lines, and ensure the roof vent isn’t clogged. 

Add Skirting Around the Base

You’ll pay between $300 and $3,000 to add skirting around the base of your mobile home. Skirting covers the space underneath a mobile home, protecting the underbelly from snow, cold, animals, and water. Skirting also helps to keep pipes from freezing under the home. Additionally, you can add insulation to the skirting for extra protection during the winter. 

Insulate Windows and Doors

You can expect to pay between $3 and $20 per square foot to insulate your windows and doors. Insulating includes caulking and installing insulation or weatherstripping around doors and windows. These measures prevent heat from escaping and cold air from coming in.

Insulate Pipes

Professional pipe insulation costs between $1.10 and $11 per linear foot. Because mobile home pipes are underneath the house, you’ll want to use sturdy foam insulation or wrap heat tape around the pipes to prevent them from freezing.

Exterior Caulking

You’ll pay between $25 and $50 to caulk the exterior siding of your mobile home. Look for cracks, gaps, and holes in the siding and apply caulk. Exterior caulking will keep cold air out and warm air in.

Install Storm Windows

You’ll pay around $55 per square foot to install storm windows on your mobile home. Storm windows are essential if you live in an area with high winds, heavy snowfall, or hurricanes. Storm windows protect the windows underneath and keep out cold, harsh air.

Roof Inspection

You can expect to pay between $125 and $343 for a roof inspection. A roof inspection is crucial to keep a mobile home in good condition. A roof inspection will determine whether you need to replace shingles, tar the stacks and vents, repair edges and seams, or coat the entire roof with a metal roof coating.

Roof Insulation

Insulating your roof will cost between $0.50 and $3.50 per square foot. Insulating the roof of your mobile home entails pumping insulation into the roof’s interior, sealing off any seams in the roof, and caulking around any gutters and plumbing.

Clean Gutters

You can expect to pay between $119 and $228 for a gutter cleaning. Cleaning the gutters is crucial to help keep water flowing and prevent ice dams. Ice dams can cause damage to your roof and interior ceiling.

Repair Water Leaks Under the Home

You’ll pay an average of $500 to have a plumber repair water leaks underneath your mobile home. Because water lines are exposed underneath the house, they are more likely to leak and burst. So, before winter sets in, make sure to repair leaks and fully insulate pipes underneath your mobile home.

Empty Garden Hoses

You’ll pay between $56 and $131 for a pro to winterize your garden and sprinkler system. Winterizing garden components include:

• Removing garden hoses from exterior spigots

• Fully draining them

• Ensuring faucets face a downward slope

Location

Homes in regions with heavy snow and high winds typically cost more to winterize than those in milder climates. Homeowners in snowy areas should also budget for related add-ons, such as an annual snow removal contract at $200 to $600 per season or a cover for your AC unit ranging from $40 to $150.

Mobile Home Size

A larger mobile home generally costs more to winterize because it has more windows, doors, roofing, and pipes that need insulation. Mobile homes fall into one of three size categories, and costs vary accordingly.

• Single-Wide: 500–1,200 sq. ft.

• Double-Wide: 1,000–2,200 sq. ft.

• Triple-Wide or Multi-Wide: 2,000+ sq. ft.

Age

The age of your mobile home is a key cost driver, since older homes tend to have less insulation and weaker protection from the elements, which can mean full component replacements rather than simple seasonal prep. Replacement costs vary significantly by component, so the breakdown below can help you plan your budget.

• Pipe Replacement: $363 to $2,011

• Furnace Replacement: $2,114 to $7,706

• Roof Replacement: $4.35 to $11 per sq. ft.

• Hot Water Heater Replacement: $874 to $1,755

DIY Winterizing a Mobile Home vs. Hiring a Pro

If you’re handy and have the time, you can tackle many mobile home winterization projects yourself. You’ll only need to pay for the cost of materials, and you’ll save on labor costs.

Otherwise, you can hire a handyperson near you to do most of the tasks on your winterization list. This will cost between $50 and $100 per hour. For furnace service, we always recommend hiring an HVAC specialist. And for winterizing your pipes, you should hire a plumber near you —and you can expect to pay between $45 and $150 per hour.
