Benefits of winter-proofing your manufactured house


You will get the most from your mobile home investment with proper pre-season inspection and maintenance. A maintained mobile home will help you save on utility bills and repair costs. That means the manufactured house is functioning on an optimal level, and not strain the structural components or overwork the utility systems that will have a massive impact on your monthly budget.

Perhaps the most important benefit you will receive is a high quality of life. That spells out better comfort, especially during the cold season. Enjoying a warm beverage during a snowfall is so much better if you do not have to worry about a slew of issues like freezing pipes and cold air passing through the wall cracks and holes.

How to keep a mobile home warm during winter

There is a lot more you can do to ensure your mobile home is “winterproofed”. Mobile home winterizing involves activities more than just adding extra insulation and caulking gaps. A pre-season inspection is necessary to minimize encountering issues during the winter.

It is essential to find critical issues early on and repair them while there is still time. That is why home inspection services are often sought months before the cold weather arrives. However, doing an initial inspection of your mobile home on your own is not a bad idea.

Follow this mobile home winterizing checklist below if you want to winterize your mobile home like a pro. To prevent catastrophe from happening, follow the list below.


1. Check furnace and heating

  • Ensure that your mobile home is not going to freeze during the wintertime. Check whether your furnace and heating system are working and patch up any leaks. The furnace base and boot are not immune to gaps and holes. Use a mastic sealant or aluminum foil to fill the gaps and holes that can be found anywhere between or around the supply to the return air ducts.
  • Is your thermostat still working? Consider upgrading to a better one that can provide more functions. In this day and age, there are several brands of thermostats that can be connected to the internet or your smartphone for easy control.
  • If you have a furnace, one of the things you should have in your mobile home is a furnace filter. Change your filter regularly to avoid the accumulation of dust and dirt that could block the heat.

2. Inspect the entire manufactured home

  • Examining your mobile home from top to bottom is crucial to guarantee your property is winterproof. Inspect the walls, floors, and roof that needs repair or replacement.
  • Clean your gutters to ensure water will flow without any problems. Clogs on the gutters will accumulate ice that will not only make the manufactured house feel colder but will also damage its structure.
  • Install leaf guards to prevent fallen leaves from clogging the gutter. The gutter must be free of any debris.
  • Every entry and exit points like doors and windows might have slight gaps that should be sealed. Once you find them, use an adhesive weatherstrip or filler to patch up the spaces.
  • Install a mobile home skirting as a deterrent from animals that are seeking a place to hibernate during the cold season.
  • Purchase new pipelines if the currently installed tubes are old, rusted, bent, and about to break.

3. Seal entry points

  • Replace broken window glass. If necessary, upgrade the whole window pane to a style that is best in cold locations, especially during winter.
  • Prevent cold breeze from reaching the interior of your manufactured home by patching up holes and filling window or door gaps.
  • According to the National Renewable Energy Laboratory or NREL, adhering to these air sealing procedures will have the biggest impact on winterizing your mobile house.
  • Caulking and putting weatherstripping has about 50 to 150 airflow reduction CFM.
  • Installing tight windows can reduce airflow by about 100 to 250 CFM.
  • Patching up ceilings, floors, and walls where air can leak can reduce airflow for about 200 to 900 CFM.

4. Securing the crawl space

  • Updating your mobile home skirting is a great idea to cover the bottom of the house. There are several manufactured home skirting materials you can find in stores like metal, plywood, faux rock, bricks, and hardy board. Use the material that is best for your location and the intensity of cold weather.  Click here for the latest skirting designs
  • It is important to do maintenance work from time to time, so make sure to allow access to the crawl space.
  • To prevent moisture from seeping into the subfloor area, lay down a thick plastic sheet or vapor barrier on the ground. 10 mil ground vapor is usually the recommended option for long-term protection and excellent puncture resistance.

5. Extra precautionary measures


  • Checking forced-air heating systems
    • Most mobile homes are equipped with forced-air systems. The HVAC ducting system can become frozen or covered with a layer of ice due to frozen moisture that builds up over time, under the home. If left disregarded, it can cause huge disasters.
    • Change the heating or air conditioning filters regularly. 
    • Inspect the refrigerant level now and then. When condensation happens due to low refrigerant, the moisture could turn into ice and block the airflow. Eventually, the system will break.
  • Sealing exhaust fans
    • Manufactured houses are required to have exhaust fans. It is essential to caulk the sides and corners of the fan to avoid cold air from passing through.
  • Draining water lines when leaving the house for a couple of days
  • Drain any standing water from the faucets, showers, sinks, or toilet bowls to avoid pipes and drainage from freezing. A plunger is an effective tool to break up the clog that is causing the water to move slowly.
  • Check the main water valve before leaving the house. Shut it off to avoid a water leak that can freeze and damage the pipe.
  • Go to each sink and pour a cup of drain cleaner to ensure food debris is not trapped inside the pipes
  • Let the water drip from hoses and exterior faucets. Make sure to release water that has been trapped inside the garden hose.
  • Insulating the pipes
    • Wrap the plumbing system of your mobile home with insulation foam. This will prevent the pipes from freezing and avoid heat loss, when heat tape is used. Use either a T-bone or elbow foam connections for insulating corners and complex angles of the pipes. Make sure all pipes are fully covered.
    • Pipes that are exposed and without heating systems are especially vulnerable to freezing. Installing heat tape to your pipes will help keep the metal or plastic pipe with trapped water from freezing and bursting from the cold temperature.

We hope you learned from this manufactured home winterizing checklist. Hands down, performing a pre-season inspection and maintenance will beat out common mobile home problems that often happen during winter.
