Southern California Seasonal Maintenance Guide

In this guide, we'll provide actionable steps to maintain your home in Southern California throughout each season.


Inspect Roof and Gutters

Before the rainy season begins, inspect your roof for cracked or missing tiles and other potential issues. Clean out gutters and downspouts to ensure proper drainage and prevent water buildup.

Waterproof Exterior Surfaces

Check the exterior walls for cracks and seal them to prevent water damage. Apply waterproofing compounds where necessary, especially around windows and doors.

Service Heating Systems

Though heating needs are limited in Southern California, it’s wise to have any heating systems checked and serviced to ensure they are operational for the colder nights.

Prepare for Winds and Rain

Secure or store outdoor furniture and other loose items that could be blown away or damaged during high winds. Trim trees and remove dead branches to reduce the risk of them falling during storms.

Check Smoke and Carbon Monoxide Detectors

Ensure that your smoke detectors and carbon monoxide detectors are functioning correctly. Replace batteries and test these devices regularly.


Service Air Conditioning Units

Prepare for the heat by servicing your air conditioning units. Clean or replace filters, check ducts for leaks, and ensure the system is running efficiently.

Enhance Landscape Efficiency

Optimize your irrigation systems to prevent water waste. Consider drought-tolerant plants for garden updates and check mulch levels to maintain soil moisture.

Inspect and Repair Screens

Inspect screens on windows and doors for tears or holes to keep insects out during the warmer months. Repair or replace damaged screens.

Conduct a General Cleaning

Spring is an ideal time for a thorough cleaning of exterior home surfaces, windows, and outdoor living spaces.

Pest Control

Inspect for pests more common in warm weather, such as ants and termites. Seal up entry points and treat areas as necessary.


Maintain Cooling Systems

Continue to check and replace the air conditioning filters monthly. Clear any debris from around the condenser unit and check for efficient operation.

Prepare for Wildfires

Create and maintain a defensible space by clearing dry brush at least 100 feet from your home. Use fire-resistant landscaping strategies to further protect your property.

Check for Water Leaks

Inspect hoses, faucets, and irrigation systems for leaks, as water waste is a significant concern during the dry months.

Manage Indoor Air Quality

Use dehumidifiers if needed, and keep your living spaces well-ventilated to manage indoor air quality, especially during times of outdoor smoke and haze.

Solar Panel Maintenance

Clean solar panels if you have them; dust and debris can reduce their efficiency.


Prepare for Rainy Season

Clear gutters and downspouts again to prepare for the rains. Inspect the roof once more for any issues that may lead to leaks during prolonged rainfall.

Insulate Windows and Doors

Check the seals around windows and doors; replace weatherstripping if necessary to keep your home comfortable and energy-efficient.

Test Heating and Air Systems

Although minimal, the use of heating systems might increase slightly. Ensure they are functional and ready if needed.

Garden and Lawn Preparation

Plant winter crops if you garden, and adjust the watering schedule for cooler weather and potential rain.

Pest Reinforcement

Continue monitoring for pests as the climate cools and creatures seek warm shelters. Address any infestations immediately.

Review Emergency Preparedness

Update your emergency kits with supplies for power outages, potential earthquakes, and other regional emergencies.
