LA sun, Santa Ana winds, and winter rain wear down your home's exterior fast. Here's a system-by-system exterior maintenance checklist to catch small problems before they get expensive.
Exterior home maintenance means checking and refreshing your home's outer shell on a schedule. Do it twice a year and you catch small problems while they're cheap to fix. Skip it, and LA's intense sun, dry heat, and winter rain quietly turn a $20 tube of caulk into a rotted window frame.
This guide walks you through home exterior upkeep system by system. Use it as your exterior maintenance checklist each spring and fall. For a whole-home version that covers the inside too, see our Los Angeles home maintenance checklist.
Key Takeaways
- Walk your home's exterior at least twice a year, in spring and fall, and after big storms or Santa Ana wind events.
- LA's biggest threats are UV damage in summer and water intrusion in winter. Both start small and get expensive.
- Water and freezing damage is one of the most common home insurance claims, averaging around $15,400 (Insurance Information Institute, via This Old House, 2025).
- Sealing air leaks around doors and windows saves homeowners about 15% on heating and cooling (ENERGY STAR).
- Know when to stop: call a roofer or licensed pro for structural roof, major electrical, or gas work.
Why LA weather is hard on your home's exterior
Los Angeles gives your home two seasons of stress. Summer brings months of intense, direct UV and dry heat. That sun breaks down paint, dries out caulk, and cracks wood and rubber seals.
Then the pattern flips. Santa Ana winds peak in fall, driving embers and debris (NOAA). Winter rain follows, roughly November through March. Any gap the summer sun opened up is now a place for water to get in. Good exterior upkeep works with that cycle: prep for sun, then prep for rain.
Roof, flashing, and gutters
Start at the top, because roof and gutter problems cause the most expensive damage.
Inspect your roof twice a year and after major storms. From the ground with binoculars, look for cracked, curled, or missing shingles. An asphalt shingle roof typically lasts 20 to 30 years, so an older roof needs a closer look (InterNACHI). Check the flashing around chimneys, vents, and skylights for lifted edges or failed sealant.
Clean your gutters at least twice a year, and more often under heavy tree cover. Clogged gutters overflow and dump water against your fascia, siding, and foundation instead of away from it. Our step-by-step guide on how to clean gutters covers the safe way to do it.
Water and freezing damage is one of the most common and costly home insurance claims, averaging roughly $15,400 (Insurance Information Institute, via This Old House, 2025). A few hours of gutter work is cheap insurance against that.
When to call a roofer: if you see interior ceiling stains, sagging, widespread damaged shingles, or any structural issue, stop and call a licensed roofing pro. Walking a roof is dangerous, and structural roof work is beyond handyman scope.
Paint, caulk, and siding
Your paint and caulk are the exterior's raincoat. LA sun is hard on both.
Check exterior paint for fading, chalking, and peeling. UV breaks down the binders in paint, so it wears faster here than in milder climates. Most exterior paint lasts several years, but intense sun exposure shortens that (This Old House). Touch up bare or peeling spots promptly. Exposed wood or stucco soaks up water fast.
Re-caulk gaps around windows, doors, and where siding meets trim. Dried, cracked caulk is a direct path for water and pests. Run a bead of fresh exterior sealant anywhere the old line has shrunk or split.
Wash your siding once a year. Rinse off dust, cobwebs, and the gray film that builds up in dry months. Clean siding lasts longer and lets you spot cracks or soft spots you'd otherwise miss.
Wood: fences, decks, and rot
Wood is where deferred maintenance shows up first. Sun dries it out and rain rots it.
Reseal your deck and fence on a schedule. Horizontal deck boards take the worst of the sun and foot traffic, so plan to re-stain them every two to three years. Vertical surfaces like fences and siding last longer, closer to three to five years (This Old House).
Not sure if it's time? Use the water-bead test. Splash a little water on the wood. If it soaks in instead of beading up, the seal is gone and it's time to reseal.
Probe for rot at fence-post bases, deck stairs, and any wood near the ground. Press a screwdriver into suspect spots. Soft, spongy wood needs to be cut out and replaced before it spreads.
Doors, windows, and seals
Your seals do two jobs: keep water out and keep conditioned air in.
Check weatherstripping and door sweeps. Sun and age make them brittle and cracked. Replace any that are flattened, torn, or letting daylight through. This is a small, cheap fix with a real payoff. Sealing air leaks and adding insulation saves homeowners an average of about 15% on heating and cooling costs (ENERGY STAR).
Also inspect the seals on sliding doors and garage-door thresholds. Those get skipped, and they're a common way water sneaks in during winter storms.
Ground level: foundation, grading, and paving
Water should always flow away from your house, not toward it.
Check your grading. The soil around your foundation should slope away from the house, dropping at least 6 inches over the first 10 feet (InterNACHI, per IRC R401.3). If a flower bed or settled soil slopes back toward the wall, rain pools against the foundation. Regrade it or add soil to restore the fall.
Scan the foundation for new cracks, especially after the rainy season. Hairline cracks are common. Wide, growing, or horizontal cracks are a reason to call a pro.
Seal driveway and walkway cracks before winter. Water gets in, and LA's temperature swings widen the gaps over time. A quick fill keeps small cracks from becoming trip hazards and bigger repairs.
Test outdoor faucets and irrigation in early fall. Look for drips, cracked hose bibs, and broken sprinkler heads. A leaking faucet against the house feeds moisture right where you don't want it.
Vegetation and defensible space
In LA, trimming plants off the house isn't just tidy. It's fire safety.
Keep branches and shrubs away from the walls and roof. Overhanging limbs drop debris in your gutters and give embers a path to the house. Cal Fire recommends keeping the first 5 feet around your home clear of anything that can burn, part of a 100-foot defensible space zone required in high-risk areas (Cal Fire / Ready for Wildfire).
Clear dead plants, trim tree limbs off the roofline, and move woodpiles and combustible mulch away from siding. For the full seasonal routine, read our guide on wildfire season home prep in Los Angeles.
When to handle it yourself, and when to call a pro
Most of this checklist is homeowner-friendly: gutters, caulk, weatherstripping, resealing wood, and touch-up paint. It's steady, low-drama work that pays for itself.
Call a licensed specialist when the job crosses into structural roof repair, major electrical, or gas. If you'd rather hand the whole exterior punch list to one person, a good handyman can knock out most of it in a visit or two. Here's how to find a good handyman in Los Angeles you can trust.
Frequently asked questions
How often should I do exterior home maintenance?
Do a full exterior walk-around twice a year, in spring and fall. Add a quick check after any major storm or Santa Ana wind event. That rhythm matches LA's sun-then-rain cycle.
What's the most important exterior task in Los Angeles?
Managing water. Clean gutters, good grading, and fresh caulk keep winter rain out of your home. Water intrusion causes the most expensive, hardest-to-reverse damage.
Can a handyman do exterior maintenance?
Yes. Gutter cleaning, caulking, weatherstripping, wood resealing, minor rot repair, and touch-up paint are all standard handyman work. Structural roof, gas, and major electrical jobs need a licensed specialist.
