Michigan winters can be beautiful, but they are undeniably harsh, bringing freezing temperatures, heavy snow, and strong winds. For manufactured homes, including modular housing, these conditions make winterizing especially important. With the right preparation, these homes can stay warm, energy-efficient, and protected from risks like heat loss and frozen pipes all season long.

Winterizing your home isn’t just about staying warm. It’s about reducing energy costs, protecting your plumbing, and preventing avoidable repairs. A well-winterized home will be more comfortable for you now and more appealing to buyers in the future.

Why Winterizing a Manufactured Home Is Essential

A manufactured home is constructed in a controlled factory environment and then transported to its final location. While these homes are built to meet or exceed federal or state building codes, their design includes features—such as skirting, crawl spaces, and underfloor plumbing—that benefit from a bit of extra care in winter. Addressing these areas helps any home perform at its best during Michigan’s cold season.

Without proper preparation, cold air can seep in through small gaps, forcing your heating system to work harder and driving up energy bills. Even worse, plumbing lines in uninsulated or exposed areas can freeze and burst, leading to expensive water damage.

By winterizing early, you not only improve comfort but also extend the life of your home’s systems and structure. It’s a cost-effective way to protect your investment and keep your home running efficiently throughout the cold season.

Identifying Common Sources of Heat Loss in Manufactured Homes

Knowing where heat escapes is the first step in preventing it. In manufactured and modular homes, some of the most common sources of heat loss include:

  • Windows and Doors with Air Leaks – Older or poorly sealed frames can allow cold air to seep in and warm air to escape.

  • Poorly Insulated Floors, Walls, and Roofs – Insufficient insulation lets heat pass through surfaces instead of staying inside.

  • Gaps Around Vents, Plumbing, and Wiring – Openings for utilities can create pathways for drafts.

  • Skirting Issues – Damaged or missing skirting allows cold air to circulate beneath the home, increasing heat loss and exposing pipes to freezing temperatures.

Insulation Upgrades to Keep the Heat In

Good insulation is one of the most effective ways to prevent heat loss in a manufactured home. Start by checking your attic or roof cavity—heat rises, and without proper insulation, it can escape quickly. Adding fiberglass batts, blown-in insulation, or even spray foam can make a noticeable difference.

Underfloor insulation is just as important, especially for homes with skirting. Insulating the floor and crawl space helps keep the interior warmer and protects plumbing from freezing. For walls, adding extra insulation during renovations or upgrades can improve energy efficiency year-round.

Don’t forget about sealing small gaps. Using foam board or spray foam to close off openings around utility lines, ducts, and vents helps keep warm air in and cold air out.

Protecting Pipes from Freezing

Frozen pipes aren’t just an inconvenience; they can cause significant water damage and expensive repairs. To prevent frozen pipes in manufactured and modular homes, focus on insulating any exposed plumbing, especially in crawl spaces or along exterior walls.

Foam pipe insulation is affordable and easy to install. For added protection in extreme cold, consider heat tape or cable, which warms pipes directly. Be sure to follow the manufacturer's instructions for safe installation.

During the coldest stretches, keep a slow trickle of water running through faucets connected to vulnerable pipes. This movement makes freezing less likely. Also, make sure crawl space vents are closed and skirting is in good condition to keep cold air from circulating underneath your home.

Finally, know where your main water shut-off valve is located. In the event a pipe does burst, shutting off the water quickly can minimize damage.

Sealing Air Leaks and Improving Energy Efficiency

Air leaks may seem minor, but they can have a big impact on your heating costs and comfort. Sealing drafts in your manufactured home should be part of your winterizing checklist.

Use caulk to seal gaps around window frames, door frames, and where utilities enter the home. Install weatherstripping on doors to create a tighter seal, and consider adding door sweeps to block drafts from underneath.

For windows, thermal curtains or plastic window insulation film can add an extra layer of protection against cold air. These simple upgrades not only keep your home warmer but also make your heating system work more efficiently, saving you money all winter long.

Maintaining Heating Systems for Peak Performance

A well-maintained heating system is essential for keeping your home warm and energy bills manageable during the winter. Schedule an annual inspection for your furnace or HVAC system before the cold weather sets in. A professional can check for worn parts, ensure safe operation, and optimize performance.

Replace air filters regularly, typically every one to three months during heating season, to maintain proper airflow. Clogged filters make your system work harder, which can shorten its lifespan and increase costs.

Extra Winterizing Tips for Comfort and Safety

In addition to insulation, sealing, and heating system maintenance, a few extra steps can help keep your manufactured home comfortable and safe:

  • Use a Programmable Thermostat – Adjust temperatures automatically to balance comfort and energy savings.

  • Clear Snow and Ice from Vents – Keep exterior vents unobstructed for proper ventilation and furnace function.

  • Check Smoke and Carbon Monoxide DetectorsEnsure all safety devices are in working order for the heating season.

  • Maintain Skirting – Inspect regularly to ensure panels are secure and undamaged.
