Evaluating Your Existing Wall Structure
Before selecting new siding or cladding, a thorough inspection of the existing wall structure is essential. This involves assessing the integrity of the sheathing, framing, and any current weather-resistive barrier (WRB). Look for signs of water damage, rot, insect infestation, or structural instability. Any issues discovered at this stage must be addressed and repaired before new materials are installed.
For renovations, consider the load-bearing capacity of your existing wall if you are planning to switch to a heavier cladding material. Also, evaluate the flatness and plumb of the walls; irregularities can complicate the installation of new siding and may require shimming or other adjustments to ensure a straight, professional finish. This initial assessment forms the foundation for all subsequent decisions.
Understanding Climate Considerations in Montgomery, AL
Montgomery, AL, experiences a humid subtropical climate, characterized by hot, humid summers and mild winters. This climate presents specific challenges and opportunities for facade materials. High humidity levels necessitate materials with good moisture resistance and proper ventilation to prevent mold and mildew growth. Intense sun exposure can lead to fading or degradation of certain finishes, making UV stability a key consideration.
When planning a facade renovation, consider how your chosen siding or cladding will perform under these local conditions. Materials that can withstand temperature fluctuations, resist moisture absorption, and maintain their appearance despite strong sunlight are often preferred. Proper detailing around windows, doors, and corners for water management is crucial for longevity.
Material Options for Facade Renovation
Lumber Plus offers a range of siding and cladding materials suitable for facade renovations. These include thermally modified wood, Maximo Accoya, Brazilian hardwood, and Norx composite cladding.
Thermally modified wood, such as Scandinavian thermally modified wood and thermally modified Ayous, offers enhanced stability and durability against moisture and decay. The thermal modification process alters the wood's cellular structure, making it less prone to expansion, contraction, and insect attack. This makes it a suitable option for facades requiring natural beauty with improved performance.
Maximo Accoya is an acetylated wood product known for its stability and durability. It offers a consistent, natural wood aesthetic with performance characteristics that make it highly resistant to rot and dimensional changes. This material can be a strong choice for projects seeking a long-lasting wood facade.
Brazilian hardwoods like Ipe, Cumaru, Garapa, Angelim, and Jatoba provide a dense, durable, and naturally resistant option for cladding. These species are renowned for their natural resistance to rot, decay, and insects, making them robust choices for exterior applications. They offer a range of rich colors and distinctive grain patterns. However, they may require more significant structural support due to their density.
Norx composite cladding provides a low-maintenance alternative. Made from a blend of wood fibers and recycled plastics, composite cladding resists rot, splinters, and insect damage. It often comes in pre-finished colors, reducing the need for painting or staining. This can be a practical choice for renovations where ease of maintenance is a priority. (Source: S1)
Considering Profiles and Installation Systems
The profile of your chosen siding or cladding material significantly impacts the final aesthetic and the installation method. Common profiles include tongue-and-groove, shiplap, and board-and-batten. Each profile creates different shadow lines and visual textures.
Beyond the profile, the installation system is critical. Many modern cladding systems utilize a rainscreen principle, which involves creating a ventilated air gap between the cladding and the weather-resistive barrier. This gap allows moisture to drain and promotes airflow, helping to dry the wall assembly and protect against moisture intrusion. For a facade renovation, integrating a rainscreen system may require specific furring strips or a compatible sub-framing system.
Always refer to the manufacturer's specific installation guidelines for your chosen material and profile. These documents will detail fastener types, spacing, and any required clearances or expansion gaps to ensure proper performance and longevity.
Worked Example: Renovating a 20-foot by 10-foot Wall Section
Let's consider renovating a specific 20-foot wide by 10-foot high section of a facade in Montgomery, AL, using Norx composite cladding with a 5.5-inch (nominal 6-inch) face width. The total area is 200 square feet. This section has one window, 3 feet wide by 4 feet high, centered horizontally and vertically.
First, calculate the actual cladding area needed: 200 sq ft (total wall) - (3 ft * 4 ft) (window) = 188 sq ft. Norx composite cladding is typically supplied in fixed lengths, for example, 16-foot boards. Each 16-foot board with a 5.5-inch face width covers (16 ft * 12 in/ft * 5.5 in) / 144 sq in/sq ft = 7.33 sq ft per board.
To cover 188 sq ft, you would theoretically need 188 / 7.33 = 25.65 boards. However, you must account for waste from cuts, especially around the window, and potential breakage. A common waste factor for siding projects is 10-15%. For this example, let's use 10% waste: 25.65 boards * 1.10 = 28.2 boards. Therefore, you would typically purchase 29 boards to ensure sufficient material.
This calculation assumes horizontal installation. If installing vertically or diagonally, the cut plan and waste factor might differ. Always create a detailed cut list for complex areas like windows and doors to minimize waste and optimize material usage. Ensure the existing wall can support the weight of the new cladding and that the chosen installation method is compatible with the existing structure and local weather conditions.
Before you order
- Have I thoroughly inspected the existing wall structure for damage, rot, or instability?
- Is the existing wall sufficiently flat and plumb for the chosen siding material?
- Have I considered the specific climate conditions of Montgomery, AL (humidity, sun exposure, storm potential) in my material selection?
- Does my chosen material (thermally modified wood, Accoya, hardwood, composite) meet my aesthetic and performance requirements?
- Is the chosen siding profile compatible with the desired architectural style and installation method?
- Have I planned for a proper rainscreen assembly with an air gap and drainage if suitable for my chosen material and climate?
- Do I have a detailed understanding of the manufacturer's installation guidelines for the specific product?
- Have I calculated the material quantity, including a realistic waste factor, and accounted for all openings?
- Will the existing structure adequately support the weight of the new cladding material?
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 difference between siding and cladding?
While often used interchangeably, 'siding' typically refers to materials that form the outermost layer of a wall system, providing weather protection and aesthetic finish. 'Cladding' is a broader term that encompasses any material applied to the exterior of a building to provide a skin or layer, including decorative panels, stone, or metal. Both serve to protect the building envelope and enhance its appearance.
Do I need a building permit for facade renovation in Montgomery, AL?
Many facade renovation projects, especially those involving structural changes or significant alterations to the building envelope, may require a building permit from the City of Montgomery. It is crucial to check with the local building department before starting any work to understand specific requirements, codes, and inspection schedules. Failure to obtain necessary permits can lead to fines and delays.
How do I maintain my new siding or cladding?
Maintenance requirements vary significantly by material. Thermally modified wood and hardwoods may benefit from periodic cleaning and reapplication of UV-protective finishes to maintain their color, or they can be allowed to weather naturally. Composite cladding generally requires less maintenance, typically just cleaning with soap and water. Always follow the specific maintenance recommendations provided by the manufacturer of your chosen siding or cladding material to ensure its longevity and appearance.
