What Does Winterization Mean for an Empty Home?

Winterization is the process of preparing a home to withstand cold temperatures when it won’t be regularly occupied. Unlike homes that are lived in year-round, vacant properties don’t benefit from daily heat, water use, or routine checks.

For empty homes, winterization focuses on:

• Preventing frozen or burst pipes
• Reducing moisture and mold risk
• Protecting appliances and systems
• Minimizing costly winter damage

A thorough winterization plan helps ensure you return to a home that’s just as you left it.

Start With the Plumbing System

Drain and Protect Water Lines

One of the most critical winterization steps is protecting your plumbing. Frozen pipes are among the most common and expensive winter problems for vacant homes.

To reduce risk:

• Shut off the main water supply
• Drain all faucets, both hot and cold
• Flush toilets to remove standing water
• Drain appliances like dishwashers and washing machines

In some cases, homeowners also add non-toxic antifreeze to drains and toilets for extra protection. This step is especially important in colder climates.

Don’t Forget Outdoor Plumbing

Exterior faucets, hoses, and irrigation systems are often overlooked during winterization. Make sure to disconnect and store garden hoses, shut off water to outdoor spigots, and drain sprinkler systems completely. Taking care of outdoor plumbing helps prevent hidden leaks that may go unnoticed for months.

Manage Heating Wisely During Winterization

Set a Safe, Consistent Temperature

Even when a home is empty, it’s usually safer to keep the heat on at a low level rather than shutting it off entirely. Maintaining a consistent indoor temperature helps prevent pipes from freezing inside walls and crawl spaces.

Many homeowners set thermostats between 50–55°F, depending on local conditions. Smart thermostats can be especially helpful, allowing you to monitor and adjust settings remotely.

Service the Heating System Before You Leave

Before winter arrives, schedule a professional inspection of your furnace or heating system. A quick tune-up ensures it runs efficiently and reduces the risk of breakdowns while the house is vacant. This proactive step is a small investment that supports your overall winterization strategy.

Seal the Home Against Cold Air and Moisture

Insulate and Seal Entry Points

Drafts can cause cold spots inside your home, increasing the risk of freezing. As part of winterization, check for air leaks around windows and doors, attic access points, and basements and crawl spaces. Weatherstripping, caulk, and insulation upgrades can make a noticeable difference, even in older homes.

Protect Against Moisture Buildup

Empty homes are more susceptible to moisture issues because there’s no daily airflow from normal living activities. Consider using dehumidifiers in basements, moisture absorbers in closets, and proper ventilation where needed. Managing humidity helps prevent mold and musty odors during long periods of vacancy.

Prepare Appliances and Interior Spaces

Unplug and Clean Appliances

Appliances that won’t be used for months should be cleaned and unplugged. Leaving refrigerator and freezer doors slightly open can help prevent odors and mold. If your home has a water heater, consult a professional about whether it should be drained or set to vacation mode as part of your winterization plan.

Secure Windows, Doors, and Valuables

Winterization isn’t only about temperature—it’s also about security. An empty home can attract unwanted attention. Before leaving, lock all windows and doors, consider timed lights or smart security systems, and ask a trusted neighbor to check in periodically. These steps help protect your home from both weather and security risks.

Remember Exterior Winterization, Too

Clear Gutters and Downspouts

Clogged gutters can lead to ice dams and water damage during winter storms. Cleaning gutters before winterization helps ensure melting snow drains properly away from the home.

Prepare the Yard and Roof

Trim tree branches near the house, store outdoor furniture, and inspect the roof for loose shingles. Exterior preparation supports the overall winterization process by reducing storm-related damage.

Should You Hire a Professional for Winterization?

Some homeowners handle winterization themselves, while others prefer professional services, especially for vacant or remote properties. Hiring a professional can be helpful if the home is in a very cold climate, plumbing systems are complex, or you want documentation for insurance purposes. Professional winterization services often follow detailed checklists to ensure nothing is missed.

Why Winterization Is a Smart Long-Term Investment

Proper winterization helps protect your home’s systems, structure, and value. Preventing just one major issue, like a burst pipe, can save thousands in repairs and restoration. It also reduces stress. Knowing your home is prepared allows you to focus on travel, work, or seasonal living without constant worry.

Winterization is one of the most responsible steps homeowners can take when leaving a house empty during cold months. From plumbing protection to heating management and moisture control, each step works together to safeguard your investment.
