How Do You Maintain Your Home's Siding?
Maintaining your home's siding protects it from weather, moisture, and pests—and it doesn't take much to make a big impact. Whether you have fiber cement, cedar, aluminum, or board and batten siding, a few simple steps each season can extend its lifespan and keep your home looking its best.
In this guide, the siding experts at Nelson Exteriors share essential siding maintenance tips for every major material, plus a seasonal checklist to help Atlanta homeowners stay ahead of costly repairs.
Why Siding Maintenance Matters
Consistent siding maintenance helps prevent serious problems like mold, rot, and structural damage. Well-maintained siding can also improve energy efficiency by keeping your home sealed against drafts and moisture. And if you're thinking long-term, it's worth noting that clean, damage-free siding boosts curb appeal and resale value.
The bottom line: taking care of your siding now saves you from costly replacements later.
Board & Batten Siding Maintenance
Board and batten siding offers timeless charm and is commonly made from wood or fiber cement. Use the following siding maintenance tips to keep it in top condition:
- Inspect annually for gaps, loose boards, or cracks.
- Repaint and reseal wood siding every 5-7 years to prevent weather damage. James Hardie® siding typically lasts 9-10 years between paint cycles, offering longer-lasting protection and lower maintenance.
- Wash gently using a soft brush or garden hose to remove dirt and mildew. Avoid pressure washers unless handled by a professional—improper use can damage your siding.
- Watch for insect and moisture damage, especially at the base and around windows.
- Check for caulk failure at seams if using fiber cement board.
Aluminum Siding Maintenance
Newer aluminum siding is low-maintenance but still needs occasional attention to maintain its appearance and integrity:
- Wash annually with water and a mild detergent to remove dirt and buildup.
- Inspect for dents and corrosion, especially after storms.
- Repaint every 10-15 years to refresh color and protect the surface.
- Clean chalking or oxidation with a vinegar and water solution.
- Check for loose fasteners and make small repairs as needed.
Cedar Siding Maintenance
Cedar siding delivers natural warmth but requires regular care to keep it looking great and protected from the elements:
- Stain or seal every 3-5 years to guard against moisture and sun damage.
- Inspect regularly for signs of rot, carpenter ants, and termites.
- Power wash gently once per year, using low pressure to avoid surface damage.
- Keep shrubs and plants trimmed back to maintain airflow and prevent moisture buildup.
- Monitor for fading or peeling, and refresh the finish as needed.
Fiber Cement Siding Maintenance
Fiber cement, like James Hardie products, offers durability with minimal upkeep. Follow these siding maintenance tips to extend its life:
- Inspect caulk joints annually and reapply caulk where it's cracked or failing.
- Clean annually using a soft cloth or sponge and a garden hose.
- Avoid pressure washing, which can damage the siding surface.
- Repaint every 9-12 years to preserve color and protect the material.
- Check flashing and trim for signs of moisture intrusion.

Metal Siding Maintenance
Modern metal siding—like steel or zinc—can last for decades with proper care. Here's how to maintain its appearance and prevent corrosion:
- Hose down biannually to remove pollutants, dust, and debris.
- Inspect fasteners and seams for rust or corrosion.
- Touch up scratches or chips with paint made for metal siding.
- Ensure proper drainage around your home's foundation to reduce the risk of rust.
- Keep gutters clean to avoid water runoff damaging the siding surface.

FAQs About Siding Maintenance
How do you clean cedar siding without damaging it?
To clean cedar siding safely, use a garden hose or low-pressure washer with a soft-bristle brush and mild soap. Avoid harsh chemicals or high-pressure washers, which can strip the wood and force moisture into the grain. Always rinse thoroughly and allow the siding to dry completely. Regular cleaning helps maintain the wood's natural beauty and prevents mold or mildew buildup.
How long does fiber cement siding last with proper maintenance?
With proper care, fiber cement siding like James Hardie can last 30 to 50 years or more. Key siding maintenance tips include cleaning it gently once a year, inspecting caulk joints annually, and repainting every 9-12 years. Keeping moisture out and maintaining a strong exterior seal are essential for maximizing its lifespan.
Is pressure washing siding safe?
Pressure washing is not safe for all siding types, especially if you are not a professional. It is acceptable at a low pressure done by a professional on almost all siding types, but at a high pressure, or done by someone with little or no experience, it can damage wood, cedar, vinyl, fiber cement, and even brick! If you must pressure wash, keep the pressure below 1,500 PSI and spray at a downward angle to avoid forcing water behind the siding.
What's the best way to prevent mold on board and batten siding?
Preventing mold on board and batten siding starts with regular cleaning and inspection. Ensure your siding is properly sealed and painted, especially if it's wood. Keep vegetation trimmed back and maintain good drainage around your home. Avoid water pooling near the foundation and ensure gutters and downspouts are functioning properly to reduce moisture exposure.
How do I know if my siding needs to be replaced?
Signs your siding may need replacement include cracking, warping, bubbling paint, visible mold or rot, or a dramatic increase in energy bills. If you notice soft spots, loose boards, or moisture intrusion, it's time for a professional inspection. The team at Nelson Exteriors can assess the condition of your siding and recommend the best course of action to protect your home.
