Dos and Don'ts of Fiber Cement Siding Maintenance

Fiber cement siding is known for its strength, weather resistance, and low maintenance, making it a favorite for homeowners seeking durability with visual appeal. However, even low-maintenance materials require proper care to maintain their integrity and appearance. To help you make the most of your investment, here are the essential dos and don’ts of fiber cement siding maintenance, especially for homes in Fort Wayne, IN.

Do: Clean Regularly with Gentle Methods

Routine cleaning keeps your siding looking its best and prevents dirt, grime, and mildew from taking hold.

• Use a soft cloth, sponge, or soft-bristle brush to gently clean the surface

• Wash with a mild detergent and water

• Rinse with a garden hose or low-pressure washer

Avoid using abrasive tools or harsh chemicals, which can damage the paint or siding surface.

Don’t: Use High-Pressure Power Washers

While power washers can seem like a quick fix, they often do more harm than good on fiber cement siding. High pressure can force water behind panels, leading to moisture damage, mold, and rot. Stick to low-pressure rinsing to maintain your siding's durability.

Do: Inspect and Repair Caulking

Check the caulking around joints, windows, doors, and trim annually. Fort Wayne's fluctuating weather conditions can cause sealants to crack or shrink.

• Reapply exterior-grade, paintable caulk when needed

• Ensure all gaps are sealed to keep moisture and pests out

Don’t: Ignore Small Issues

Cracks, chips, or peeling paint may seem cosmetic, but they can lead to bigger problems. Unattended damage can allow moisture to infiltrate and compromise your siding’s performance. Address small repairs promptly to avoid costly fixes later.

Do: Repaint When Necessary

One of fiber cement’s advantages is its ability to hold paint for years—often 10–15 with proper application. When the color fades or begins to peel:

• Use 100% acrylic exterior paint

• Repaint under dry, mild conditions

• Apply at least two coats for best results

Refreshing the paint maintains your home’s curb appeal and protects the siding from environmental wear.

Don’t: Delay Routine Inspections

Check your siding at least once a year—ideally in spring or fall. Look for signs of:

• Peeling paint

• Loose panels

• Mold or mildew

• Damaged caulking or flashing

In Fort Wayne, IN, where seasonal weather is tough on exteriors, consistent inspections help you catch early signs of wear and weathering.

Do: Trust Professional Maintenance When Needed

Sometimes it’s best to leave repairs or repainting to professionals. Improper care or incorrect products can shorten the lifespan of even the best siding.
