Main takeaway: Before leaving home for the holidays, check plumbing connections, inspect appliances, clear drainage areas, and consider shutting off your main water supply when appropriate. A few preventive steps can help reduce the risk of returning to unexpected water damage.
Water damage prevention should be part of your holiday travel preparations. Whether you’re leaving Hilton Head Island for a few days or closing up a seasonal property in Bluffton or Beaufort, taking a few precautions before departure can help protect your home from unexpected plumbing leaks, appliance failures, and water damage.
While you’re away, a small plumbing leak or appliance malfunction can go unnoticed. Without someone home to discover the problem, water may spread into flooring, cabinets, drywall, and other building materials.
Following these seven water damage prevention tips can help reduce the risk of returning home to costly damage after your holiday travels.
Why Water Damage Can Be Worse When No One Is Home
Water damage doesn’t always begin with a major pipe burst or obvious flooding.
A loose plumbing connection, leaking appliance hose, or slow drip beneath a sink may release water for hours or days before anyone notices.
When moisture remains undetected, it can spread beyond the original source and affect surrounding materials.
Depending on the conditions, prolonged moisture exposure may contribute to:
- Swollen or damaged cabinets
- Warped flooring and damaged subfloors
- Stained or deteriorating drywall
- Moisture trapped behind walls or beneath flooring
- Microbial growth in affected areas
- Damage to personal belongings
For homeowners with vacation properties or second homes in the Lowcountry, regular inspections and preparation before extended absences are especially important.
Water damage prevention is especially important for vacation homes and seasonal properties that may remain unoccupied for extended periods.
7 Water Damage Prevention Tips Before Holiday Travel
Taking time to inspect your home before leaving can help you identify potential problems and reduce the risk of water damage while you’re away.
1. Inspect Plumbing Fixtures and Supply Lines
Check beneath kitchen and bathroom sinks for signs of moisture, corrosion, or loose plumbing connections.
Pay particular attention to:
- Toilet supply lines and shutoff valves
- Sink plumbing and cabinet interiors
- Washing machine hoses
- Refrigerator water lines
- Dishwasher connections
- Water heater connections
Regular plumbing inspections are an important part of water damage prevention, particularly before leaving your home unattended for several days.
Look for water stains, damp surfaces, discoloration, or other signs that a leak may already be developing.
If you discover a problem, have it evaluated and repaired before leaving.
2. Consider Shutting Off Your Main Water Supply
One way to reduce the risk of water damage during an extended absence is to shut off the home’s main water supply when appropriate.
Doing so may help limit damage if a plumbing supply line fails while no one is home.
However, shutting off the water may not be suitable for every property. Some homes have systems that require a continuous water supply, including certain fire sprinkler systems, heating equipment, or other specialized installations.
Before turning off the main valve, make sure you understand how it affects your home’s plumbing and mechanical systems.
If you’re unsure, consult a qualified plumber or the appropriate service professional.
For additional guidance on protecting your property from preventable damage, visit the Insurance Institute for Business & Home Safety (IBHS) for home safety and disaster preparedness resources.
3. Check Washing Machines, Dishwashers, and refrigerators
Household appliances are common sources of unexpected water leaks.
Before holiday travel, inspect visible hoses and connections for signs of wear, cracking, or moisture.
Avoid starting a dishwasher or washing machine immediately before leaving if no one will be home to monitor the cycle.
If your refrigerator has a water dispenser or ice maker, inspect the accessible supply connection and check for signs of leaking.
Consider replacing damaged or deteriorating hoses before they fail.
4. Inspect Your Water Heater
Water heaters can develop leaks around fittings, valves, and the tank itself.
Check the area around your water heater for:
- Standing water
- Rust or corrosion
- Damp flooring
- Water stains
- Unusual Dripping
If you notice signs of a leak, arrange for a professional inspection.
For extended travel, consult the manufacturer’s instructions or a qualified professional about whether an appropriate vacation setting or other precaution is recommended.
5. Clear Gutters and Check Exterior Drainage
Not all water damage begins inside the home.
Heavy rain and poor drainage can allow water to collect near foundations, doors, and other vulnerable areas.
Before leaving:
- Remove leaves and debris from gutters when safe to do so.
- Check the downspouts to direct water away from the building.
- Inspect accessible drainage areas for blockages.
- Look for signs of water collecting near exterior walls.
- Check doors and windows for visible gaps or deteriorated seals.
In coastal communities such as Hilton Head Island and Bluffton, Keeping drainage systems maintained is an important part of protecting a home from water intrusion.
Exterior maintenance also plays a role in water damage prevention by helping rainwater away from vulnerable areas of your home.

6. Use Water Leak Detectors for Added Protection
Water leak detectors can provide an additional layer of protection when a property is unoccupied.
These devices are often placed near areas where leaks may occur, including:
- Beneath sinks
- Behind washing machines
- Near water heaters
- Around refrigerators with water lines
- In other areas with accessible plumbing connections
Some smart leak detectors can send alerts to your phone when moisture is detected. Certain systems can also be paired with automatic water shutoff devices.
Although these tools cannot prevent every type of water damage, they may help homeowners respond sooner when a leak occurs.
Including leak detection technology in your water damage prevention plan may help you identify plumbing problems sooner, even when you’re away from home.
7. Ask Someone to Check Your Property
If you’ll be away for an extended period, consider arranging for a trusted person or property manager to check your home.
Regular visits may help identify:
- Unexpected water leaks
- Damp flooring or cabinets
- Water stains on ceilings or walls
- Unusual indoor humidity
- Signs of exterior water intrusion
This can be particularly helpful for seasonal residents and second-home owners in Hilton Head Island, Bluffton, and surrounding Lowcountry communities.
Make sure the person checking your home knows how to contact you and what to do if they discover an emergency.
What to Do If You Return Home to Water Damage
Even with careful preparation, unexpected water damage can still occur.
If you discover water damage after returning from a trip, taking the right steps can help reduce additional problems.
- Identify the source if it is safe to do so. If the water is coming from a plumbing fixture or supply line, shut off the appropriate valve when possible.
- Avoid electrical hazards. Do not enter areas with standing water near electrical outlets, appliances, or equipment. Contact a qualified professional when needed.
- Document visible damage. Take photographs of affected areas and belongings before cleanup when it is safe.
- Contact your insurance provider. Report the damage and follow your insurer’s instructions for documenting the loss.
- Arrange for a professional assessment. Water may extend beneath flooring, into wall cavities, or behind cabinets even when visible damage appears limited.
Prompt water extraction, moisture assessment, and appropriate drying can help limit further damage. Professional water damage restoration services can help identify hidden moisture and determine the appropriate steps to restore affected materials.
Why Hidden Moisture Matters After a Leak
One of the challenges with water damage is that the visible wet area may not show the full extent of the problem.
Water can travel along framing, beneath flooring, and into adjacent materials before becoming noticeable.
Even after standing water is removed, moisture may remain trapped in building materials.
Professional water damage restoration involves identifying affected areas, documenting moisture conditions, and determining which materials can be dried in place and which may require removal.
Addressing hidden moisture is an important part of restoring a property after a leak.
