Cedar cladding is a popular choice for homeowners seeking both durability and aesthetic appeal for their properties. Its natural beauty, resistance to decay, and ability to withstand harsh weather conditions make it an ideal option for exterior siding. However, proper installation and maintenance are crucial to preserve its longevity and charm.

Preparing for Installation

Selecting the Right Cedar

Before diving into the installation process, it’s essential to choose the right type of cedar for your cladding project. Western Red Cedar is often preferred due to its natural resistance to decay and insects, as well as its stunning reddish-brown color. Ensure that the cedar you select is kiln-dried and free of defects to prevent issues down the line.

Preparing the Surface

Proper preparation of the surface is key to a successful installation. Begin by inspecting the substrate for any signs of damage or moisture. Repair any defects and ensure the surface is clean and dry before proceeding. Installing a weather-resistant barrier, such as house wrap, can also help protect the underlying structure from moisture infiltration.

Installing Cedar Cladding

Choosing the Right Fasteners

When it comes to fastening cedar cladding, stainless steel nails or screws are the preferred choice. These fasteners are durable and resistant to corrosion, ensuring a secure installation that will withstand the test of time. Be sure to use the appropriate length and gauge of fasteners to accommodate the thickness of the cedar boards.

Proper Installation Techniques

Start by laying the first course of cedar boards at the bottom of the wall, ensuring that they are level and properly aligned. Use a spirit level to check for accuracy and adjust as necessary. Install subsequent courses, staggering the joints for added strength and visual appeal. Leave a small gap between boards to allow for natural expansion and contraction due to changes in temperature and humidity.

Finishing Touches

Once the cedar cladding is installed, apply a high-quality finish to protect it from the elements and enhance its natural beauty. Semi-transparent stains and clear sealers are popular choices, as they allow the wood’s grain to show through while providing adequate protection against UV rays and moisture.

Maintaining Cedar Cladding

Regular Inspections

To ensure that your cedar cladding remains in top condition, perform regular inspections to check for any signs of damage or wear. Look for cracks, splits, or areas of discoloration, as these may indicate underlying issues that need to be addressed.

Cleaning

Periodic cleaning is essential to remove dirt, grime, and mildew that can accumulate on the surface of cedar cladding over time. Use a mild detergent and water solution, along with a soft-bristle brush or sponge, to gently scrub the wood’s surface. Avoid using high-pressure washers, as these can damage the wood fibers and lead to premature deterioration.

Refinishing

Over time, the finish on cedar cladding will naturally wear away due to exposure to the elements. When this occurs, it’s important to refinish the wood to restore its protective properties and enhance its appearance. Begin by thoroughly cleaning the surface, then apply a fresh coat of stain or sealer according to the manufacturer’s instructions.
