Even in Southern California, seasonal home maintenance is essential. While Santa Monica enjoys a temperate climate year-round, winter still brings increased moisture, cooler temperatures, and occasional stormy weather. Preparing a property for the winter months helps preserve its value, protect its systems, and maintain a comfortable environment. For homeowners who value both aesthetics and performance, winter prep in Santa Monica should strike a balance between coastal considerations and long-term property care. Megan Whalen, an experienced local real estate professional, helps clients understand what it takes to keep high-value homes in peak condition through every season.
Inspect Roofing And Drainage Systems
One of the most critical winter maintenance tasks for Santa Monica homeowners is evaluating the roof and drainage system before the rainy season arrives. Although the region receives significantly less rainfall than many other parts of the country, sudden winter storms can still bring heavy downpours that test a home’s defenses.
Roofing materials should be inspected for wear, lifting, or broken shingles, especially in older homes or homes that have recently undergone remodels. Santa Monica’s proximity to the coast can accelerate roof deterioration due to salt air exposure, so even homes with newer roofs may be vulnerable. Homeowners should ensure flashing is intact around chimneys, skylights, and vents to prevent water infiltration.
Gutters and downspouts should be thoroughly cleared of leaves and debris to allow proper drainage. Blocked gutters can overflow during storms, leading to water pooling around the foundation or even interior water damage. Proper water flow through downspouts should direct runoff away from the home to reduce the risk of flooding or erosion in landscaped areas.
Seal Windows And Doors Against Drafts
Although Santa Monica winters are milder than in colder climates, nighttime temperatures often dip into the 40s and low 50s. Drafty windows and doors can lead to discomfort and unnecessary energy use. Checking for air leaks around windows and entryways is a simple yet effective way to improve insulation and reduce heating costs.
In older homes, original wood windows may be charming but often lack the thermal efficiency of modern designs. If full replacement isn't on the table, weather stripping and caulking around window frames can offer a noticeable improvement. Door thresholds and seals should also be examined, particularly in high-use areas like patio entrances or front doors that face the ocean breeze.
Upgraded windows with dual-pane glass or Low-E coatings can further increase energy efficiency. For Santa Monica homeowners with views worth preserving, these modern window treatments offer comfort without compromising aesthetics.
Service HVAC Systems And Clean Filters
Winter preparation should include a full check of the home’s heating and air systems. While Santa Monica homes may rely more on air conditioning than heat for most of the year, efficient climate control is still essential during cooler months.
HVAC systems should be inspected and serviced by a licensed technician before the start of the season. This ensures that heating functions properly when needed and helps prevent unexpected breakdowns. Regular maintenance also extends the life of high-efficiency systems, which are common in luxury homes throughout the Santa Monica area.
In homes with air purifiers or high-end filtration systems, winter is a good time to replace filters and clean ducts. As windows remain closed more often, indoor air quality becomes increasingly important. Keeping vents and registers free of dust and debris allows the entire system to perform more efficiently.
Maintain Outdoor Spaces For Winter
Santa Monica's outdoor lifestyle doesn’t stop during winter, but adjustments are necessary to protect patios, landscaping, and exterior furniture. Irrigation systems should be checked for leaks and properly adjusted to accommodate cooler temperatures and natural rainfall. Overwatering is a common issue during winter and can lead to root rot or soil erosion.
Furniture cushions, umbrellas, and decorative pieces should be stored or covered during periods of rain or extended damp weather. For homeowners with outdoor kitchens or entertainment areas, protective coverings can preserve finishes and prevent corrosion from salt air and moisture.
Trimming trees and shrubs, particularly those near the home or power lines, reduces the risk of storm damage. Coastal winds and rain can cause limbs to fall or rub against roofing and siding. Keeping landscaping tidy also contributes to curb appeal during showings if the property is on the market during the winter season.
Check For Moisture And Mold In Vulnerable Areas
Even small amounts of excess moisture can cause problems if not addressed early. Winter weather, though mild, can introduce humidity and damp conditions that create ideal environments for mold and mildew, especially in homes near the beach or in canyon-adjacent neighborhoods like Santa Monica Canyon or Pacific Palisades.
Attics and crawl spaces should be checked for signs of moisture or musty odors. Installing dehumidifiers or improving ventilation in these areas can significantly reduce the chance of mold growth. Bathrooms, laundry rooms, and kitchens should also be reviewed to ensure that fans and exhaust systems are working efficiently.
Coastal homes with open floor plans and large windows may experience condensation buildup during the cooler months. Regularly wiping down window sills and monitoring indoor humidity levels can help prevent subtle water damage over time.
Protect Smart Home Features And Systems
Luxury homes in Santa Monica often include advanced technology and smart home systems that require extra attention during seasonal changes. Backup batteries for security systems, sensors, and automated thermostats should be tested and replaced if necessary. Any devices that are sensitive to temperature fluctuations or moisture, such as exterior cameras or smart irrigation hubs, should be checked for weather resistance or temporarily relocated if needed.
Pool systems, solar panels, and outdoor lighting installations should also be reviewed for winter compatibility. While most systems are built to endure the California climate, performing seasonal checks helps avoid disruptions and ensures long-term functionality.
Preserve Value With Seasonal Maintenance
Ongoing maintenance is part of preserving any home’s value, but it’s especially vital in a high-demand, luxury market like Santa Monica. Whether a homeowner plans to stay long-term or list their property in the coming months, proactive winter preparation helps avoid costly repairs, keeps systems running efficiently, and ensures the home remains show-ready at all times.
Well-maintained homes also tend to move faster when listed, particularly in the cooler months when buyers are looking for turnkey properties that won’t require immediate attention. Small efforts now can translate into long-term peace of mind and a smoother real estate experience down the line.
