Owning a coastal home offers a place to retreat, gather and enjoy time near the water. However, when the residence remains unoccupied between visits, changes in indoor humidity may occur without anyone being there to notice the early signs.
Humidity is not simply a comfort concern. Excess indoor moisture can contribute to condensation, musty odors and changes in certain furnishings, finishes and building materials. It may also indicate that the HVAC system is not operating as expected or that another moisture source should be evaluated.
The U.S. Environmental Protection Agency recommends keeping indoor relative humidity below 60 percent and, when possible, ideally between 30 and 50 percent. The appropriate settings and equipment for an individual residence should be determined with guidance from the homeowner’s HVAC professional and the manufacturers of the home’s systems.
What can change while a home is unoccupied?
A coastal residence may experience changing weather, high outdoor humidity, power interruptions, HVAC concerns or an unexpected water issue while its owners are away.
Potential warning signs may include:
- Condensation on windows, walls or pipes
- A persistent musty or damp odor
- Unexpected thermostat or humidity readings
- Reduced or unusual airflow
- An HVAC system that does not appear to be operating normally
- Visible water near plumbing fixtures or appliances
- Changes in flooring, cabinets, walls or ceilings
- Damp areas or discoloration
- Unusual sounds from mechanical equipment
These observations do not automatically establish that damage or mold is present. They indicate that the homeowner may need additional information or an evaluation by an appropriate professional.
Consistency makes the information more useful
One reading provides a moment in time. Consistent property-watch visits can provide a clearer record of conditions inside the residence.
Depending on the agreed-upon care plan, a visit may include:
- Recording the thermostat temperature
- Recording the visible indoor humidity level
- Confirming that the HVAC system appears to be operating
- Looking for visible condensation or moisture
- Observing plumbing areas, ceilings, walls and flooring
- Noting unusual odors or sounds
- Taking timestamped photographs
- Comparing current observations with previous visits
- Promptly notifying the homeowner when something appears unusual
This documentation allows the homeowner to make informed decisions and determine whether an HVAC technician, plumber, roofer, remediation company or another qualified professional should be contacted.
Remote technology and local observation
Smart thermostats, leak sensors and humidity monitors can provide useful information when an owner is away. However, technology may not show every condition inside or outside the home.
A local visual visit can help determine whether a remote alert corresponds with something observable at the property. Likewise, an in-person observation may reveal a concern that has not triggered a device notification.
Technology and professional property-care visits can work together to provide the homeowner with more complete information.
Established and newly completed homes both require attention
Humidity monitoring is relevant to established coastal residences and newly completed homes.
An established home may have familiar seasonal patterns, aging equipment or previous maintenance concerns. A newly completed home may still be settling into its first seasons of use, with systems and interior materials responding to changing coastal conditions.
In either case, a documented routine can help homeowners understand what is normal for their residence and recognize when something has changed.
A thoughtful presence while you are away
Coastal Property Care provides scheduled visual property-watch visits, documentation and homeowner communication for established coastal homes and newly completed residences.
Our role is to observe agreed-upon areas, document visible conditions and communicate concerns. Property-watch visits are visual and non-invasive. They are not professional home inspections, mold assessments, engineering evaluations, security services, licensed repairs or guarantees against equipment failure, weather damage, moisture, mold, theft or other loss.
When a concern is observed, the homeowner decides which qualified professional should evaluate or address it. Vendor access and coordination may be available according to the homeowner’s care plan.
