What Happens to a House When It Sits Empty?

Risks Every Homeowner Should Understand

Many homeowners assume that if a house is locked up and the heat is on, everything will be fine while they are away. In reality, homes are complex systems that function best when they are lived in and regularly observed.

When a house sits empty for extended periods—whether for travel, seasonal relocation, or managing a property from afar—small problems can develop quickly and sometimes go unnoticed until they become costly repairs.

At DCN Property Management, we regularly check homes throughout Concord, Lincoln, Carlisle, Acton, and surrounding communities. Over the years we’ve seen how quickly issues can arise when a home is left unattended.

Here are some of the most common risks homeowners should be aware of when a property sits empty.

Water Leaks
Water damage is one of the most common issues discovered in vacant homes.
Even a small leak from a supply line or appliance can continue for days or weeks if no one is present to notice it.

Common sources of leaks include:

• washing machine hoses
• water heaters
• refrigerator water lines
• plumbing under sinks
• sump pump failures
  
  

Many homeowners now install water leak detectors, such as the Govee WiFi Water Leak Detector or the Moen Smart Leak Detector, which send alerts to a smartphone if moisture is detected. These devices provide an early warning system that can prevent significant damage.

Heating System Failures
During colder months, heating system failures can become a serious concern for homes in New England.
If a furnace stops working and the temperature inside the house drops, pipes can freeze and burst quickly.

Smart thermostats such as the ecobee Smart Thermostat Premium or Google Nest Thermostat allow homeowners to monitor temperatures remotely and receive alerts if conditions change.

David’s Tip:
When a home sits empty during the winter, we recommend keeping the thermostat set no lower than 55°F to help protect plumbing systems.

Moisture and Basement Issues
Basements are particularly vulnerable to moisture problems, especially during seasonal transitions or heavy rains. If humidity levels rise or a sump pump fails, mold and water damage can develop quickly.

Some homeowners use monitoring tools like:

• the Govee WiFi Hygrometer Thermometer to track humidity
• the Basement Watchdog Sump Pump Alarm to detect rising water levels
• a hOmeLabs Basement Dehumidifier to control excess moisture

Monitoring basement conditions can help identify potential issues early.

Security Concerns
An unoccupied home can also become more vulnerable to security issues.

Simple steps that can help protect a property include:

• installing outdoor lighting
• using security cameras
• maintaining regular property visits

Many homeowners install camera systems such as the Blink Outdoor Camera System or Ring Spotlight Camera, which allow them to check on their property from a smartphone.

Small Problems Can Grow Quickly
One of the biggest challenges with vacant homes is that small problems may go unnoticed for extended periods of time. A minor issue—such as a small leak, heating malfunction, or moisture buildup—can grow significantly if no one is present to identify it early. Regular property checks help ensure that homes remain safe, secure, and well maintained even when homeowners are away.

Final Thoughts
Homes require ongoing attention, even when they are unoccupied. Technology has made it easier for homeowners to monitor their properties remotely, but regular inspections and preventative maintenance remain essential.

Understanding the potential risks of leaving a home unattended can help homeowners take simple steps to protect their property and avoid unexpected surprises.
