Evaluating Existing Wall Conditions
Before any new siding or cladding is installed, a detailed assessment of the existing wall structure is essential. This includes inspecting for water damage, rot, insect infestations, and any signs of structural compromise. The condition of the sheathing, framing, and existing moisture barrier will dictate the scope of the renovation, potentially requiring repairs or upgrades before new materials can be applied.
For projects in areas like Bend, OR, where seasonal temperature fluctuations and precipitation can be significant, verifying the integrity of the moisture management system is particularly important. Look for evidence of proper flashing around windows, doors, and penetrations. Any deficiencies here must be addressed to prevent future water intrusion, regardless of the new cladding choice.
Understanding Your Wall Assembly Documentation
Accessing original construction documents, if available, can provide invaluable insights into the existing wall assembly. These documents may detail the layers of the wall, including insulation, vapor barriers, and air gaps, which are critical for specifying new materials. Understanding the original design intent helps in making informed decisions that maintain or improve the building's performance.
In the absence of original documentation, a careful deconstruction of a small section of the existing wall may be necessary to understand its composition. This allows for a visual inspection of each layer, helping to identify potential issues or opportunities for improvement in the new facade design. This step is particularly important for ensuring compatibility between new cladding and existing structural elements.
Material Selection: Thermally Modified Wood
Thermally modified wood offers enhanced stability and durability, making it a suitable option for facade renovations. This process involves heating wood to high temperatures, altering its cellular structure to improve resistance to decay and moisture absorption. Lumber Plus offers Scandinavian thermally modified wood, which provides a clean grain for contemporary facades.
Examples include thermally modified Ayous and Ash, which can be specified in various profiles. Its lighter weight compared to some hardwoods can also be a consideration for existing structures. Thermally modified wood is a good choice when a natural wood aesthetic is desired with increased dimensional stability.

Material Selection: Maximo Accoya and Brazilian Hardwoods
Maximo Accoya is an acetylated wood product, distinct from thermally modified wood, known for its exceptional durability and stability. It resists rot and insect attack, and its consistent performance makes it a strong candidate for facade renovations where longevity is a primary concern. Accoya can be milled to various profiles, offering design flexibility.
Brazilian hardwoods such as Ipe, Cumaru, Garapa, Angelim, Jatoba, and Tigerwood are known for their natural strength and distinctive appearance. These woods offer a range of colors and grain patterns, from the bold grain of Ipe to the deep red of Jatoba. While naturally durable, their density and weight require careful consideration of the existing structure's capacity and proper fastening techniques.

Material Selection: Norx Composite Cladding
Norx composite cladding offers a low-maintenance alternative to natural wood, combining wood fibers with synthetic materials. This results in a product that resists fading, staining, and insect damage, often requiring less upkeep over its lifespan. Norx composite is available in various finishes and profiles, including options like London Black, providing a modern aesthetic.
Composite cladding can be an excellent choice for facades requiring a consistent appearance with minimal maintenance, which can be advantageous in climates with fluctuating weather. Its uniform dimensions and ease of installation can also contribute to a smoother renovation process.

Worked Example: Facade Renovation on a 1980s Home
Consider a hypothetical 1980s single-family home in Bend, OR, with existing T1-11 plywood siding that shows signs of delamination and dry rot near the base. The homeowner desires a modern, low-maintenance facade. The existing wall measures approximately 30 feet wide by 10 feet high on the front elevation, totaling 300 square feet.
Upon inspection, the underlying studs are sound, but the existing moisture barrier (tar paper) is brittle in several areas. The decision is made to remove the T1-11, repair localized sheathing damage, install a new continuous weather-resistive barrier, and then apply new Norx composite cladding with a horizontal profile.
Assuming a Norx composite board is 6 inches wide (0.5 feet) and available in 12-foot lengths. For a 30-foot wide wall, each row would require three 12-foot boards (36 feet total per row) to avoid excessive short cuts. For a 10-foot high wall with 6-inch wide boards, this would mean 20 rows (10 feet / 0.5 feet per board). Thus, 20 rows * 3 boards/row = 60 boards. Each board is 12 feet long, so 60 boards * 12 feet/board = 720 linear feet. This example illustrates how material dimensions impact purchase quantities beyond simple square footage.
Before you order
- Inspect existing wall for water damage, rot, and structural integrity.
- Identify existing moisture barrier and flashing conditions.
- Obtain or create a diagram of the existing wall assembly layers.
- Determine the structural capacity of the existing framing for new cladding weight.
- Assess desired aesthetic: natural wood, contemporary composite, or rich hardwood.
- Consider long-term maintenance requirements for each material.
- Evaluate material durability and stability in local climate conditions.
- Confirm compatibility of new cladding with existing windows, doors, and penetrations.
- Plan for proper ventilation and drainage behind the new cladding.
- Calculate material quantities based on exact profile dimensions and waste factors.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.

Questions to help you decide
What is the most important factor when renovating a facade?
The most important factor is a thorough assessment of the existing wall conditions and understanding the current wall assembly. Addressing any underlying issues like moisture damage or structural deficiencies before installing new cladding is crucial for the long-term success and durability of your renovation.
Can I mix different types of siding on my facade?
Yes, mixing different types of siding and cladding can create visually interesting and dynamic facades. However, it requires careful planning to ensure compatibility in terms of installation methods, flashing details, and aesthetic balance. Consider how different materials will interact with each other and the overall architectural style of your home.
How do I ensure my new siding will perform well in Bend, OR's climate?
To ensure performance, select materials known for their durability and stability in varying temperatures and precipitation. Proper installation, including a robust weather-resistive barrier, adequate flashing, and a well-designed rainscreen system (if applicable), is essential. Regular maintenance tailored to your chosen material will also contribute to its longevity.
