If you’ve noticed a chalky residue, fading, or a dull, weathered look on your vinyl or aluminum siding, you’re likely dealing with oxidation.

It’s a common issue for homeowners, especially those with older siding or homes exposed to a lot of sun and weather.

Left untreated, oxidation not only affects curb appeal but can also lead to long-term damage.

What Is Oxidation and Why Does It Happen?

Oxidation occurs when the surface of vinyl or aluminum siding reacts with oxygen and UV exposure over time. On vinyl siding, this results in fading and a powdery residue. On aluminum siding, oxidation often appears as chalky buildup and a loss of luster.

Think of it like rust on metal—but instead of corroding, your siding just gets dull, faded, and less protected.

Options for Dealing with Oxidation

Here are the most common ways to address oxidation on siding, from budget-friendly to long-term solutions:

1. Professional Cleaning

• What it does: Removes surface-level oxidation using gentle detergents and soft-brush or soft-wash techniques.
• Best for: Mild to moderate oxidation.
• Cost: Typically $300–$600 depending on house size and siding condition.
• Pros: Affordable, non-invasive, no damage to the siding.
• Cons: May not restore full color if fading is severe.

2. Oxidation Removal and Restoration

• What it does: After cleaning, a specialized product is applied to restore color and shine. For aluminum, products like Everbrite are used; for vinyl, Vinyl Renu or similar are applied.
• Best for: Heavily oxidized siding that still has structural integrity.
• Cost: $600–$1,500+ depending on house size and condition.
• Pros: Restores color, adds UV protection, can last several years.
• Cons: More expensive; requires drying time and careful application.

3. Repainting

• What it does: After cleaning and prepping, the siding is painted with a high-quality exterior-grade paint.
• Best for: Severely faded or unevenly oxidized siding.
• Cost: $2,000–$6,000+ depending on surface area and labor.
• Pros: Completely transforms appearance; extends life of siding.
• Cons: Labor-intensive, higher cost, may void siding warranty.

4. Full Siding Replacement

• What it does: Replaces old siding with new vinyl, aluminum, or fiber cement siding.
• Best for: Siding with cracks, warping, or long-term UV damage.
• Cost: $8,000–$20,000+
• Pros: New materials, better energy efficiency, modern appearance.
• Cons: High cost and longer project timeline.

Why Regular Cleaning Matters

Routine exterior cleaning is one of the easiest and most cost-effective ways to prevent oxidation from getting out of hand.

• Prevents buildup of dirt, pollutants, and mold that accelerate wear.
• Protects siding materials from UV damage and moisture retention.
• Extends the life of restoration coatings or paint.
• Boosts curb appeal and home value year-round.

We recommend a professional soft wash every 1–2 years to keep siding looking great and reduce the risk of long-term oxidation.
