What should I do before leaving home to secure my house?

There’s a unique feeling that comes with locking your front door and heading out for a vacation or even just a long day at work. It’s a mix of excitement and a lingering question: did I do everything right? That small flicker of doubt is universal. Securing your house before you leave isn’t just about turning a key; it’s a peace-of-mind ritual. It’s about creating a layered defense that protects your property, your belongings, and the sanctuary you’ve built. A truly secure home is one that deters opportunists, resists forced entry, and doesn’t broadcast your absence to the wrong people.

Thinking about home security goes beyond just alarms and deadbolts. It’s a holistic approach that combines physical hardware, smart habits, and a bit of neighborhood awareness. The goal isn’t to create a fortress, but rather a home that looks occupied, feels solid, and signals to potential intruders that it’s not an easy target. By building a pre-departure routine, you transform worry into confidence. Let’s walk through the essential steps to take before you walk out that door, ensuring you can truly relax while you’re away.

The Final Walk-Through: Locked, Latched, and Lit

Before you grab your bags and head for the car, a systematic check of all entry points is the foundation of a secure home. It’s easy to focus on the front door and forget the vulnerable spots that are often overlooked.

Windows and Secondary Doors
Most people remember the main door, but windows and secondary entrances like patio sliders or basement doors are common weak points.

• Ground-Floor Windows: Go room by room and physically check every window. Don’t just look at them. Jiggle the handle and push gently to ensure the latch has actually engaged. A common mistake is think a window is locked when the latch is only partially turned.
• Upper-Level Windows: While you might think second-story windows are safe from intruders, they can still be vulnerable. More importantly, an open window, even on the second floor, is an invitation. Check that all windows on every level are firmly closed and locked. Don’t forget the garage windows or those small basement hopper windows.
• Sliding Glass Doors: These are notoriously weak. Beyond locking the handle, ensure the door is physically prevented from sliding. A simple security bar or a wooden dowel cut to size placed in the bottom track works wonders. It’s a low-cost, highly effective measure. For added security, you can also apply a security film to the glass, making it much harder to shatter.

The Garage and Shed
The garage is a major access point that many people neglect. An intruder who gets into your garage has a sheltered place to work on getting into the house itself.

• Always close the garage door. It sounds obvious, but it’s easy to drive away and leave it open.
• Lock the service door that leads from the garage into your house. This door should have a deadbolt just like your front entrance.
• Secure your shed. If your shed contains tools, ladders, or other items that could be used to break into your home, make sure it’s securely locked. A burglar can use your own tools against you.

Creating the "I’m Home" Illusion

An empty house has tell-tale signs: darkness, stillness, and accumulated mail. Modern thieves are observant and often target homes they know are vacant for a period. Your goal is to disrupt these patterns and create the illusion of regular activity.

Harnessing Light
A dark house all night is a clear signal that no one is home.

• Timers are your best friend. Use simple mechanical timers or smart plugs to turn lamps, radios, and even TVs on and off at realistic times. Instead of just one light, set a few lights throughout the house to turn on and off. A light that switches on in the living room at 7 PM and then switches off, while a bedroom light comes on at 9 PM, looks far more natural than a single lamp burning 24/7.
• Consider smart lighting. Smart bulbs can be controlled remotely via an app, allowing you to change light patterns on the fly. Some systems can even mimic your usual routine based on past behavior.
• Don’t forget the exterior. Motion-activated floodlights are excellent for deterring anyone who might approach your home under the cover of darkness. Ensure all exterior lights are working before you leave.

Managing Mail and Deliveries
A mailbox overflowing with flyers and letters is one of the biggest giveaways of an empty home.

• The Post Office Hold Service: This is a reliable and free service. You can arrange for the USPS to hold all your mail at the local post office until you return. You can do this online in just a few minutes.
• Newspaper and Magazine Subscriptions: Call and pause delivery. An accumulating pile of newspapers on the porch is a classic sign of absence.
• Package Delivery: In the age of online shopping, unexpected packages can also signal an empty home. If you’re expecting a delivery, consider having it held at a local post office or a secure locker (like Amazon Hub or a shipping store) for pickup. You can also ask a trusted neighbor to bring it inside for you.

Trash and Yard Maintenance
The appearance of your home’s exterior sends a powerful message.

• Trash Cans: If your trash day falls while you’re away, put your empty cans away after the last collection before you leave. An uncollected can left at the curb is another indicator of vacancy. Better yet, ask a neighbor to put your cans out and bring them back in for you.
• Yard Upkeep: An unkempt lawn or overgrown garden can signal to a burglar that no one is around to take care of the property. Mow the lawn and do any necessary trimming just before you leave. If you’ll be gone for an extended period, consider hiring a lawn care service. Alternatively, in winter, a neighbor can help by ensuring your walkways are clear of snow.

Securing Valuables and Sensitive Information

While prevention is key, it’s also wise to plan for the worst-case scenario. This means making it exceptionally difficult for a thief to access and profit from your most valuable items.

The Safe and Accessible Hide
A simple safe is a powerful deterrent. Bolt it to the floor or a wall stud in a discreet location like a closet or basement. It’s perfect for items that are small and extremely difficult or expensive to replace.

• Essentials like passports, social security cards, and birth certificates.
• Jewelry of significant sentimental or monetary value.
• Small electronics, spare keys for other properties, and cash.

Diversify Your Locations
Don’t put all your valuables in one place. It’s an old trope, but it’s based on sound thinking. Burglars are under pressure; they want to get in and out quickly. They will likely check the master bedroom dresser, under the mattress, and the bedside table first.

• Consider using lockable storage compartments in guest rooms or less obvious locations.
• Keep digital backups of important documents and photos on a secure cloud service or an encrypted external hard drive that you can store off-site (like at a trusted relative’s house or in a safe deposit box).
• Make a video inventory of your possessions. Walk through your home with your phone and record your belongings. This makes it much easier to file a police report and an insurance claim if the worst happens. Store this video in the cloud.

Locking Down Your Digital Life
Leaving your home empty for a while also means you need to think about digital security.

• Don’t broadcast your trip. As tempting as it is to post vacation photos in real-time, wait until you get back. Posting "Off to Hawaii for two weeks!" on social media is a digital neon sign for potential burglars.
• Check your smart devices. Ensure smart locks are properly engaged. Check your security cameras to make sure they have a clear view and sufficient battery or power. Confirm that your alarm system is armed. If you have a home security system, many companies recommend you notify them of your travel dates so they can take extra care when monitoring your alarms.

Last-Minute Checks and Final Departure Rituals

You’ve done the major work. Now it’s time for the final sweep. This should become a routine so ingrained that you could do it in your sleep. A good checklist can help ensure you don’t forget anything in the rush of leaving.

The Technology and Utility Check
This isn’t just about security; it’s also about safety and preventing costly accidents.

• Electronics: Unplug non-essential devices. This includes TVs, computers, coffee makers, and toaster ovens. This protects them from power surges and eliminates any chance of a fire from a faulty appliance. The only things you should leave plugged in are things on timers (like lamps) or essential appliances like your refrigerator.
• Water: Turn off the main water supply to your home. A burst pipe can cause tens of thousands of dollars in damage very quickly. If you’re leaving in the winter, it’s also critical to ensure your home’s temperature is set high enough to prevent pipes from freezing.
• HVAC: Adjust your thermostat to a reasonable temperature. In the summer, don’t turn the A/C completely off, as high heat and humidity can damage wood furniture, floors, and electronics. In the winter, keep the heat on to prevent freezing and to help manage humidity.

Alerting Trusted People
Security is a community effort. Don’t be afraid to ask for help.

• Your Neighbor: A good neighbor is your best security asset. Let them know your travel dates. Give them a way to reach you in an emergency. Ask them to keep an eye on your property, collect any packages that might slip through, and perhaps even park a car in your driveway from time to time.
• Your Security Company: As mentioned, if you have a monitored system, inform them of your travel dates.
• Police: In some areas, local police departments offer a "vacation watch" or "house check" program. You can fill out a form that lets them know you’re away, so they’ll pay special attention to your property during their patrols.

The Final Moment: Locking Up
This is the last step, but it’s arguably the most important. Don’t just turn the key and walk away.

• Deadbolt: Ensure the deadbolt is fully engaged by turning the key or thumb-turn until it stops.
• Jiggle the Handle: After locking the door, give the handle a firm jiggle. This simple action confirms that the locking mechanism has properly settled into the door frame. It takes two seconds and can save you from the realization that you left your door unlocked all week.
• Walk Away with Confidence: By now, you’ve done everything in your power. Your home is locked, your valuables are secure, it looks lived-in, and you have a support system in place. You’ve built a layered defense that makes your home a less appealing target. Take a deep breath, get in your car, and enjoy your trip, knowing you’ve set your home up for success in your absence.
