California homes face spring transitions unlike anywhere else in the country. The wet season ends, dry weather sets in for six months, and your house has to switch gears — from shedding rain to retaining moisture, from preventing flooding to preventing fire, and from staying warm to staying cool.
This 25-point checklist covers every essential spring maintenance task for California homes, organized by area. Spend a Saturday on these and you'll prevent thousands of dollars in summer repair costs.
Why Spring Maintenance Matters in California
California's Mediterranean climate means homes experience dramatic seasonal swings without the freeze-thaw damage other regions face — but with unique challenges of their own: drought stress, sustained UV exposure, fire risk, and hard-water mineral buildup that accelerates in warm weather.
Exterior Maintenance (10 Tasks)
1. Inspect the Roof
From the ground with binoculars, look for missing or damaged shingles, lifted ridge caps, and damaged flashing around vents and chimneys. The wet season takes a toll — catch problems now before summer heat bakes them in.
2. Clean Gutters and Downspouts
Even after the rains stop, debris accumulates fast. Clean gutters in spring to prevent late-season fire hazards from dry leaves and to allow proper drainage during occasional summer storms.
3. Check Caulking and Weatherstripping
Sun and rain damage door and window seals. Re-caulk any cracked exterior seams to prevent drafts and pest entry. See our caulking guide for technique.
4. Inspect Exterior Paint
Look for peeling, cracking, or fading. Touch up small areas now before summer UV makes them worse. Schedule full repaints for early summer.
5. Service the Sprinkler System
Test every zone, replace broken heads, adjust spray patterns, and check for leaks. California water rates make wasted irrigation expensive.
6. Trim Vegetation Away from House
Keep all plants 5+ feet from the structure for fire prevention and to prevent moisture damage to siding.
7. Clean and Inspect Decks
Sweep, wash with deck cleaner, check for loose boards or nails, and apply sealer if it's time. Pacific sun is brutal on untreated wood.
8. Service Outdoor Faucets
Check for leaks at hose bibs and replace washers. A dripping outdoor faucet is one of the biggest summer water wasters.
9. Inspect the Foundation
Walk the perimeter looking for new cracks, especially after the wet season. Mark and measure any cracks to monitor for movement.
10. Defensible Space Maintenance
If you live in a fire zone, clear all dead vegetation, leaf litter, and combustibles within 30 feet of the home. California wildfire season starts earlier each year.
Plumbing Maintenance (5 Tasks)
11. Flush the Water Heater
Sediment from the wet-season water table accumulates in the tank. Flushing extends heater life by 3–5 years — see our hard water guide for instructions.
12. Test All Toilets
Use the food coloring test to find slow leaks. A single running toilet wastes 200 gallons per day.
13. Check Under-Sink Plumbing
Look for water stains in cabinets, slow leaks at supply lines, and corrosion on shut-off valves.
14. Clean Faucet Aerators
Soak aerators in vinegar to remove mineral buildup. Restores full water pressure and prevents premature faucet failure.
15. Test the Sump Pump (if applicable)
Pour water into the pit to verify operation. Critical for homes with finished basements.
HVAC and Electrical (5 Tasks)
16. Replace HVAC Filters
Switch to a fresh filter as you transition from heating to cooling. Improves efficiency and indoor air quality.
17. Clean AC Condenser Coils
Vacuum debris and gently rinse coils with a garden hose (no pressure washer). Test the AC before peak season demand.
18. Test Smoke and CO Detectors
Press the test button on every detector and replace batteries. California requires CO detectors near every sleeping area.
19. Test GFCI Outlets
Press the TEST button on every kitchen, bathroom, and outdoor GFCI outlet. Replace any that fail to trip and reset.
20. Clean Bathroom Vent Fans
Remove the cover and vacuum the fan blades and housing. Dust buildup reduces airflow and creates fire risk.
Interior Maintenance (5 Tasks)
21. Inspect Door and Window Operation
Tighten loose hinges, lubricate locks, and address sticking doors before summer humidity changes make them worse.
22. Deep-Clean Refrigerator Coils
Pull the fridge out and vacuum the back coils. Improves cooling efficiency and reduces summer load on the compressor.
23. Reverse Ceiling Fan Direction
Switch to counter-clockwise (looking up) for summer to push cool air down and lower perceived temperature.
24. Clean Dryer Vent
Disconnect the vent from the wall and clean the duct thoroughly. Lint buildup is a leading cause of home fires.
25. Touch Up Interior Paint
Address scuffs and marks while weather is mild and ventilation easy. See our paint finish guide for sheen selection.
DIY vs. Professional
DIY: most checklist items above. Hire a pro for: roof inspection (especially on tile or steep roofs), HVAC service, water heater flush if you've never done it, electrical testing if outlets show issues, and any item you're not 100% confident handling safely.
