As the holidays arrive, many people with second homes in Monterey County leave them empty for the winter. While you are away, your home faces risks from our local weather, like heavy rain and cold snaps. An empty home can also be a target for break-ins. Over 60% of burglaries happen at residential properties, according to the FBI, and empty homes are especially at risk.
Preparing your home for winter is a key step to protect your investment. This guide gives you a checklist of before you leave for the holidays: winter prep tips for second homes in Monterey County. We will cover simple steps for homes in Carmel, Salinas, and other local areas. These tips will help keep your home safe until you return.
1. Drain and Winterize Your Plumbing System
One of the most important winter prep tips is to protect your plumbing. If temperatures drop below freezing, water in your pipes can freeze and expand. This can cause pipes to burst, leading to major water damage.

Why Location Matters in Monterey County
Winterization needs are different across the county. A home in the higher parts of Carmel Valley is more likely to freeze than a home in Pacific Grove. Even in milder coastal areas, outdoor pipes and sprinkler systems are at risk.
Actionable Steps for Winterization
To winterize your plumbing, you need to remove all the water from the pipes. This simple step can prevent expensive repairs later.
- Shut Off the Main Water Supply: Find your home's main water valve and turn it off. This is the most important step.
- Drain All Faucets: Open every faucet in the house, both hot and cold. Flush all toilets to empty the tanks.
- Drain the Water Heater: Turn off the power to your water heater. Attach a hose to the drain valve and empty the tank.
- Protect Drains: Pour a small amount of non-toxic RV antifreeze into each drain and toilet bowl. This stops any leftover water from freezing.
Having a local team check on your home is a great way to prevent problems like burst pipes. Learn more about our vacant property inspections and upkeep in Monterey County.
2. Install and Test a Backup Power System
Winter storms in Monterey County often cause power outages. For an empty home, a blackout can shut down your heat, security cameras, and other important systems. This leaves your property at risk of damage.

Why Location Matters in Monterey County
Your home's location helps decide the best backup power option. A home in a remote part of Big Sur might need a solar and battery system. A home in Salinas or Carmel Valley could use a standby generator.
Actionable Steps for Backup Power
Setting up backup power requires planning and regular checks. This ensures it will work when you need it most.
- Choose the Right System: Decide if you need to power your whole house or just key items like the furnace and security system.
- Install an Automatic Switch: An automatic transfer switch (ATS) detects an outage and starts your generator for you. This is a must-have for owners who are away.
- Test Your System Regularly: Run your generator or battery backup once a month to make sure it works correctly.
- Maintain Fuel Levels: If you have a generator, be sure it has a full and stable fuel supply. For batteries, make sure they are fully charged.
Backup power is important, but it works best with professional oversight. Our vacant home caretaker services in the Monterey Bay provide on-site support to manage these systems and keep your home secure.
3. Upgrade Your Home Security System
An empty second home can be a target for thieves. A modern security system with remote monitoring is one of the best winter prep tips for second homes in Monterey County. These systems let you check on your home from anywhere and get instant alerts if there is a problem.

Why Location Matters in Monterey County
Security needs change depending on your home's location. A home in a quiet Carmel neighborhood might need a different system than a remote home in Big Sur. Visible cameras and security signs can also scare away criminals.
Actionable Steps for Security Upgrades
A good security plan uses a mix of technology and smart practices to protect your home.
- Choose a System with Cellular Backup: Power and internet can go out during storms. A cellular backup keeps your security system online.
- Install Cameras at Key Entry Points: Place cameras to cover the front door, back door, and any ground-floor windows.
- Set Up Mobile Alerts: Program your system to send alerts to your phone if it detects motion or if a door opens.
- Test Your System: Before you leave, do a full test to make sure all cameras and sensors are working.
While technology is great, nothing beats having a person physically check on your property. Learn how our trusted home watch services in the Monterey Bay area add another layer of protection.
4. Inspect Your Roof and Gutters
Monterey County winters bring a lot of rain and wind. A damaged roof or clogged gutter can lead to serious water damage and mold. A pre-winter inspection helps make sure rainwater flows safely away from your home.

Why Location Matters in Monterey County
Winter weather affects different areas in different ways. A home in Carmel exposed to coastal moisture needs clean gutters to prevent wood rot. A property in Big Sur needs a strong roof to handle wind and falling branches.
Actionable Steps for Roof and Gutter Care
Taking care of your roof and gutters before winter will protect your home from storms.
- Schedule a Professional Inspection: Have a certified roofer check for loose shingles, damaged flashing, and other problems.
- Clear All Gutters and Downspouts: Remove leaves, pine needles, and other debris. Clogs are a top cause of winter water damage.
- Ensure Proper Drainage: Make sure downspouts point water away from your home's foundation.
- Check the Attic: Look for any signs of water stains or mold inside your attic. This can be a sign of a leak.
Getting an expert roof inspection and maintenance check is a smart move before you leave. An expert can spot small issues before they become big problems.
5. Manage Your Heating with a Smart Thermostat
You should not turn the heat completely off when you leave for winter. This can lead to frozen pipes. A smart thermostat lets you keep the heat at a safe, low temperature, which saves energy and prevents damage.
Why Location Matters in Monterey County
Heating needs depend on your home's location. A Carmel Valley home can get frosty overnight and needs careful temperature control. A coastal home in Monterey might not get as cold, but low heat helps prevent mold from the damp air.
Actionable Steps for Heating Management
Setting up your smart thermostat correctly is key to protecting your home and saving money.
- Set a Minimum "Away" Temperature: Program your thermostat to stay at 50-55°F. This is warm enough to keep pipes from freezing.
- Create a "Vacation Mode" Schedule: Use your thermostat's vacation mode to lock in your settings while you are away.
- Test Remote Access: Before you leave, use the mobile app to make sure you can control the temperature from your phone.
- Set Up Temperature Alerts: Many smart thermostats can send you an alert if the temperature inside drops too low. This gives you an early warning of a problem.
A smart thermostat gives you great information, but you need someone local to respond if you get an alert. Our caretaker and vacant home services provide that crucial on-the-ground support.
6. Secure Outdoor Areas and Landscaping
Preparing your second home for winter includes the outside too. Storms in Monterey County can bring strong winds that turn patio furniture into dangerous flying objects. Preparing your yard and patio helps prevent damage.
Why Location Matters in Monterey County
Outdoor risks change based on where your home is. A home on the Big Sur coast has to deal with strong winds and wet soil. A cottage in Carmel-by-the-Sea needs to have its patio furniture secured to keep it from blowing away.
Actionable Steps for Outdoor Security
Taking care of your home's exterior before you leave can save you from costly repairs.
- Trim Trees and Shrubs: Trim any dead or damaged branches, especially those close to your roof or windows.
- Secure All Outdoor Items: Store patio furniture, grills, and planters in a garage or shed. If you can't, use heavy-duty covers to tie them down.
- Winterize Irrigation Systems: Shut off the water to your sprinkler system and drain the lines to prevent them from freezing and cracking.
- Check Fences and Gates: Make sure fences are sturdy and that all gates are closed and locked.
Managing your yard from far away is hard. Our estate caretaker and maintenance on the Monterey Peninsula services can ensure your property is prepared and watched over all winter.
