How to Maintain Masonite Siding and When to Replace It

Spring is just around the corner, bringing the rainy season with it. As you begin your spring cleaning, make sure to add a siding inspection to your to-do list. If you live in Austin and haven’t replaced your siding yet, chances are it’s Masonite siding. It’s important to understand that Masonite, also known as hardboard siding, is made from wood fibers and resin. This composition can absorb moisture if the paint or protective coating is damaged or worn down. Over time, trapped moisture can cause damages like swelling, warping, and even rotting. Most importantly, Masonite is now a discontinued product, making repairs difficult and the need for replacements to more durable materials like James Hardie fiber cement siding more prevalent. If you notice any of these issues, you’ll likely need to find a siding replacement company to replace your damaged Masonite siding.

To avoid the need for a quick search of “Siding replacement near me,” it’s essential to regularly check your siding for cracks or signs of peeling paint. Repainting or resealing can significantly extend the lifespan of your siding, helping maintain your home’s exterior for years. While wear and tear from harsh weather is inevitable, as one of the top siding contractors in Austin, TX, we’ve seen how improper cleaning can lead to lasting damage to Masonite siding.

If you’re considering residential siding installation or siding replacement in the future, some care now can buy you time before you need a full replacement.

Step-by-Step Instructions

1. Dry Brush Off Dirt

Use a soft-bristle brush or broom to gently remove dust, dirt, and cobwebs from the surface. Be careful not to scratch the siding.

2. Prepare Cleaning Solution

Mix a mild detergent (such as dish soap) with warm water in a bucket. For tougher stains or mildew, add a cup of white vinegar. Avoid harsh chemicals that could damage the Masonite.

3. Test in a Small Area

Before applying the cleaning solution to the entire surface, test it in a small, inconspicuous area to ensure it won’t cause damage or discoloration.

4. Wash the Siding

Use a soft cloth or sponge soaked in the soapy water to gently scrub the siding. Work in small sections to prevent the soap from sitting too long. Apply more pressure for tougher dirt, but avoid scrubbing too hard to prevent scratching.

5. Rinse Thoroughly

After cleaning each section, rinse the siding with a garden hose to remove all soap residue. Always rinse from top to bottom to avoid streaks.

6. Use a Pressure Washer (Optional)

If you’re using a pressure washer, set it to the lowest setting (around 1,200–1,500 psi). Keep the nozzle 3–4 feet away from the surface, holding it at a 45-degree angle and pointing downward to avoid water getting behind the siding.

7. Dry the Siding

Use a soft, clean towel or cloth to gently pat down the cleaned areas, or let the siding air dry. Avoid abrasive materials that could scratch the surface.

8. Repeat if Necessary

For stubborn stains, you may need to repeat the cleaning process. A mixture of water and bleach (1:1) can help, but be cautious, as bleach can be harsh on both the siding and surrounding landscaping.

• Avoid wire brushes or abrasive scrubbing pads, as they can scratch or damage your siding.
• Never use high-pressure settings on a power washer; it can force water behind the siding, leading to long-term damage and the need for siding replacement.
• Regularly clean your Masonite siding to prevent dirt, mold, and mildew buildup.

By following these steps and maintaining regular care, your Masonite siding can stay in top shape, protecting your home for years to come. We hope this helps ensure your Masonite siding withstands the test of time.
