Understanding Cedar Siding: A Woodworker’s Perspective

Before we dive into the cleaning and refinishing process, it’s important to understand what makes cedar siding so special and why it requires specific care. As a woodworker, I’ve always been drawn to cedar for its unique properties.

The Allure of Cedar: Properties and Benefits

Cedar is a softwood known for its natural beauty, durability, and resistance to decay and insects. These properties make it an excellent choice for exterior siding.

• Natural Resistance: Cedar contains natural oils that act as preservatives, protecting it from rot, decay, and insect infestations. This inherent resistance is a major advantage over other wood species, reducing the need for harsh chemical treatments.
• Dimensional Stability: Cedar is less prone to warping, twisting, and shrinking than other wood species, which makes it ideal for siding applications. This stability ensures that your siding will remain straight and true, even in fluctuating weather conditions.
• Aesthetic Appeal: Cedar boasts a rich, warm color and a distinctive grain pattern that adds character and beauty to any home. Its natural beauty can be further enhanced with stains and sealers.
• Workability: Cedar is relatively easy to work with, making it a popular choice for both professional contractors and DIY enthusiasts. It cuts cleanly, holds nails and screws well, and accepts finishes readily.

Data Point: Studies have shown that cedar siding can last for 20-40 years or even longer with proper maintenance.

Different Types of Cedar Siding: Choosing the Right Approach

Not all cedar siding is created equal. There are several different types, each with its own characteristics and maintenance requirements. Understanding the type of siding you have is crucial for choosing the right cleaning and refinishing methods.

• Western Red Cedar: This is the most common type of cedar siding, known for its rich color, durability, and natural resistance to decay. It is relatively soft and easy to work with.
• Alaskan Yellow Cedar: This cedar species is known for its strength, hardness, and resistance to wear and tear. It is often used in high-traffic areas or in applications where durability is paramount.
• Incense Cedar: This type of cedar is prized for its aromatic properties and resistance to insects. It is often used for interior applications, but it can also be used for siding in drier climates.

Tip: If you’re unsure what type of cedar siding you have, consult with a local lumberyard or woodworking professional. They can help you identify the species based on its color, grain pattern, and other characteristics.

Common Problems Affecting Cedar Siding: Recognizing the Signs

Even with its natural resistance, cedar siding is still susceptible to various problems that can affect its appearance and longevity. As a woodworker, I’ve seen firsthand the damage that can occur from neglect and improper maintenance.

• Dirt and Grime: Over time, dirt, dust, pollen, and other airborne pollutants can accumulate on cedar siding, dulling its appearance and providing a breeding ground for mold and mildew.
• Mold and Mildew: These fungi thrive in damp, shady environments and can cause unsightly stains and discoloration on cedar siding. If left untreated, they can also damage the wood fibers.
• Algae: Algae growth is common in areas with high humidity and can create a green or black film on cedar siding. It can also make the surface slippery and dangerous.
• UV Damage: Exposure to sunlight can cause cedar siding to fade, discolor, and become brittle over time. UV radiation breaks down the lignin in the wood, leading to a loss of structural integrity.
• Water Damage: Excessive moisture can lead to rot, decay, and warping in cedar siding. This is especially common in areas where water can pool or accumulate, such as around gutters and downspouts.
• Graying: This is a natural process that occurs when cedar siding is exposed to the elements. The wood’s surface oxidizes and turns a silvery-gray color. While graying doesn’t necessarily indicate damage, it can detract from the siding’s appearance.

Case Study: I once worked on a project where the cedar siding was severely affected by mold and mildew due to poor ventilation and excessive moisture. The homeowner had neglected to clean the siding for years, allowing the fungi to thrive. In this case, we had to use a specialized cleaning solution and a pressure washer to remove the mold and mildew. We then applied a protective sealant to prevent future growth.

Preparing for the Cleaning Process: Safety First!

Before you start cleaning your cedar siding, it’s crucial to take the necessary precautions to protect yourself and your property. Safety should always be your top priority.

Gathering Your Supplies: The Right Tools for the Job

Having the right tools and supplies on hand will make the cleaning process much easier and more efficient. Here’s a list of essential items:

• Cleaning Solution: Choose a cleaning solution specifically designed for cedar siding. Avoid harsh chemicals like bleach, which can damage the wood fibers.
• Soft-Bristled Brush: Use a soft-bristled brush to scrub the siding gently. “Avoid using harsh chemicals or high-pressure settings, which can damage the wood. Instead, opt for gentle cleaning solutions and soft-bristled brushes.”

  Safety Precautions: Protecting Yourself and Your Property

  • Read the Instructions: Always read and follow the manufacturer’s instructions for the cleaning solution and any other products you’re using.
  • Test in an Inconspicuous Area: Before you start cleaning the entire siding, test the cleaning solution in an inconspicuous area to make sure it doesn’t damage or discolor the wood.
  • Protect Your Eyes and Skin: Wear safety glasses and gloves to protect your eyes and skin from the cleaning solution.
  • Use Ladders Safely: If you’re using ladders, make sure they are properly positioned and secured. Have someone spot you while you’re working.
  • Avoid Cleaning on Windy Days: Windy days can cause the cleaning solution to drift and potentially damage nearby plants or property.
  • Protect Your Landscaping: Cover any plants or landscaping near the siding with drop cloths to protect them from the cleaning solution.
  • Be Mindful of Electrical Hazards: Avoid spraying water near electrical outlets or wiring.
  • Consider Professional Help: If you’re not comfortable cleaning your cedar siding yourself, consider hiring a professional siding contractor.

  Personal Story: I once made the mistake of using a pressure washer at too high of a pressure setting on a cedar siding project. The result was a damaged siding with visible streaks and gouges. I learned my lesson the hard way: always test your equipment and cleaning solutions in an inconspicuous area before tackling the entire project.
