A week before a trip, the planning usually centers on flights, packing, and pet care. The house needs the same attention, because a slow leak, a tripped breaker, or an unsecured window does not wait for you to return. Home service technicians who respond to water damage say most vacation disasters start with a small problem nobody checked. The discipline is the same one that drives fall home prep: a short list of checks completed early prevents expensive surprises.
Run the same list for any nights away, whether the trip is a weekend nearby or two weeks overseas. Short trips build the habit, and the habit is what protects the house on long ones. The checks below cover plumbing, appliances, security, weather readiness, pests, and a final walkthrough you can finish in under an hour.
Check Plumbing Before You Travel
Even a trip of a night or two deserves a plumbing pass. A drip behind a vanity, under a kitchen sink, or at the base of a toilet can run for days while nobody is home, soak into subflooring, and stain the ceiling below. Scan visible supply lines, shutoff valves, and the area around the water heater for dampness, mineral staining, or corrosion. A pinhole drip in a supply line can release gallons a day against a cabinet floor, so slow leaks are the quiet damage. Run the same scrutiny you would apply when choosing a log home company: verify the details before you trust the system.
Clean drains and traps
Kitchen and bathroom drains collect hair, soap scum, and food residue, and a slow drain left unattended can back up onto the floor. Clear the strainers, flush each line with hot water, and check the traps under sinks for buildup. Guest bathrooms deserve the same pass, because a dry trap loses its water seal and lets sewer gas odors drift through the house. Run water in every sink, shower, and floor drain you will not use while you are away so the seals stay full.
Winter shutdown sequence
If the trip falls in freezing weather, shut off the main water supply and open the highest and lowest faucets so the lines drain. Shut off the water heater first so it never runs dry, and consider adding antifreeze to traps in unheated cabins. Test the main valve the week before you leave, because a shutoff that has not moved in years can seize at the worst moment. Give the sump pump a quick test too: pour water into the basin and confirm the float triggers, especially if rain is in the forecast.
Appliances, Thermostats, and Remote Monitoring
Appliances left running unattended account for a share of vacation damage claims. Unplug anything that heats, cycles, or charges while nobody is home: coffee makers, toasters, irons, space heaters, and phone chargers. Turn the water heater to vacation mode and set the thermostat to a holding temperature that protects pipes without heating an empty house. A sensible baseline is 55 F in winter and 85 F in summer, with the water heater on its lowest setting.
Remote monitoring changes the math, because a sensor can tell you the moment a basement floods or a freezer warms. Leak detectors under sinks, freeze alarms in crawl spaces, and smart shutoff valves close the water supply automatically when a sensor trips. These tools catch problems the same way AI tools that spot red flags in home listings do: they flag trouble early, while a small issue can still be fixed cheaply.
| System | Setting before you leave | Why it matters |
|---|---|---|
| Water heater | Vacation or low mode | Cuts standby energy loss |
| Thermostat | 55 F winter / 85 F summer | Prevents freezing, saves energy |
| Main water | Off in freezing weather | Stops burst pipes and floods |
| Sump pump | Tested and cleared | Handles rain while you are away |
| Freezer | Full and door sealed | Holds temperature during outages |
Set the thermostat for the season
Winter travel calls for a thermostat no lower than 55 F so pipes in exterior walls stay above freezing. Summer travel calls for a higher setting that keeps humidity in check without conditioning an empty house. Programmable thermostats make the change automatic, and some vacation modes hold a wider temperature band while you are away.
Smart sensors and water alarms
Battery-powered leak detectors cost little and alert your phone the moment moisture appears. Place them under the water heater, washing machine, dishwasher, and each bathroom sink. Freeze alarms serve the same role in garages and crawl spaces where pipes run close to exterior walls.
Security, Access, and Emergency Contacts
Decide who can enter the house while you are gone and write it down. A neighbor, relative, or property manager should hold a key, the alarm code, and a note about pets and plants. Home service professionals recommend designating one emergency contact who can check the property in a worst-case scenario: a storm, a burst pipe, or an alarm that will not stop. Reviewing the access plan before you go is like reviewing log home packages and bundles before you commit: the terms are easier to settle in advance than in the middle of a problem.
Locks, lights, and timers
Confirm every exterior door deadbolts and every window latches. Skip the obvious hiding spots for spare keys and give the spare to your contact instead. Put interior lights on timers or smart bulbs that mimic your usual schedule, and keep one exterior light on overnight. A house that looks occupied is a poor target.
- Deadbolt every entry door and lock the garage service door
- Set interior lights on timers in at least two rooms
- Leave the spare key with the emergency contact, not under the mat
- Cancel mail and package delivery or arrange a pickup hold
- Close and latch all ground-floor windows, including basement hoppers
Lighting schedules that look lived-in
Timer schedules work best when they vary: kitchen light in the evening, bedroom light at night, and a bathroom light that comes on briefly in the morning. Smart bulbs can randomize the pattern, which reads as activity to anyone watching the house. Set the schedules before you pack so you can test them one evening in advance.
Alarms and cameras
Test the security system before you leave and confirm the monitoring service has current contact numbers. Doorbell cameras and exterior cameras let you check the property from anywhere, and they give the emergency contact a way to see what is happening before they drive over. Leave instructions for what counts as an emergency worth a visit.
Exterior and Weather Readiness
The outside of the house takes the first hit from wind, rain, and snow while you are away. Clear gutters and downspouts so a heavy storm cannot overflow water against the foundation, and confirm downspout extensions carry runoff several feet from the wall. Check the roof for lifted shingles or flashing gaps, trim branches that overhang the roof, and move potted plants, grills, and loose furniture inside or tie them down. Deciding where water goes matters as much as finding the right building site for a new home: drainage settled in advance protects everything downstream.
Gutters, downspouts, and grading
Gutters full of leaves send water over the edge and straight down the foundation wall. Scoop them clean, confirm downspouts discharge away from the house, and check that the soil next to the foundation slopes away. A few inches of positive grading moves water where you want it instead of into the basement.
Lawn, trees, and seasonal work
Mow the lawn before you leave and arrange for someone to keep up with it on longer trips. Cut back branches that could scrape the roof in a windstorm and tie down anything the wind can lift. In winter, shut off and drain outdoor hoses, and line up snow removal so the driveway stays passable for the emergency contact.
Pest Prevention and Food Storage
An empty house is an invitation to pantry pests and rodents. Take out the trash, wipe down counters, and store opened food in sealed containers. Put pet food away, because a left-out bowl is a direct food source for ants and mice. Walk the perimeter and seal gaps around pipes, vents, and door bottoms where pests enter, and set traps in the garage and basement as a first line of defense. Looking for entry points is the same exercise as studying log home photo tours for design clues: details surface only when you look deliberately.
Kitchen and pantry
Wipe down surfaces, take out compost and recycling, and check the pantry for open bags of flour, sugar, and cereal. Freeze pantry staples that might carry insect eggs for 48 hours before storing them long term. Leave the dishwasher cracked open so it dries completely.
Perimeter and entry points
Caulk gaps around utility lines, replace worn door sweeps, and confirm vents have screens. Rodents squeeze through openings the size of a pencil, so a quarter-inch gap is enough to matter. Check the attic and crawl space for signs of nesting before you close the house up.
The Final Walkthrough
The morning you leave, do one deliberate pass with the checklist in hand. Confirm the main water shutoff if you are traveling in winter, the thermostat setting, the stove burners, and the back door. Check that the sump pump runs, the freezer door is sealed, and the mailbox is cleared. The same verify-everything habit that guides buying raw land for a home site applies here: one careful pass beats three hurried ones.
A checklist you can reuse
Keep the list on the fridge or in a notes app so it works for every trip. Short trips build the routine, and the routine is what protects the house on long ones. A final five-minute loop through plumbing, kitchen, doors, and thermostat turns a rushed departure into a calm one.
- Walk the water heater, under-sink cabinets, and toilet bases for dampness
- Confirm the thermostat, water heater mode, and freezer door
- Check stove burners, unplug small appliances, and take out the trash
- Deadbolt doors, arm the alarm, and note the time the timers switch on
- Lock up, and text the emergency contact that the house is sealed
