Assessing Existing Wall Conditions
The first step in any facade renovation is a comprehensive assessment of the existing wall. This includes identifying the type of construction (e.g., wood frame, masonry), the condition of the sheathing, and the presence of any moisture damage, rot, or structural issues. Inspect for signs of water intrusion around windows, doors, and rooflines. Understanding the current wall assembly will inform decisions about vapor barriers, insulation, and rainscreen systems.
For older homes, especially those in coastal areas like Annapolis, existing walls may lack modern moisture management features. A renovation can be an opportunity to upgrade these elements, ensuring the new siding or cladding performs optimally and protects the underlying structure. Documenting these conditions with photos and notes is essential for planning.
Understanding Your Material Options
Lumber Plus offers a range of siding and cladding materials suitable for various aesthetic and performance requirements. These include thermally modified wood, Brazilian hardwood, and Norx composite cladding.
Thermally modified wood, such as Scandinavian Thermally Modified Wood, is engineered for enhanced stability and resistance to environmental factors, making it a suitable choice for exterior applications. Materials like thermally modified Ayous and Ash offer clean grain for contemporary facades. Maximo Accoya, an acetylated wood product, provides another option with its own distinct properties and applications.
Brazilian hardwoods like Ipe, Cumaru, Garapa, Angelim, Jatoba, and Tigerwood offer natural durability and a range of rich tones and grain patterns. These dense woods are known for their strength and impact resistance. Norx composite cladding provides a low-maintenance alternative, available in various finishes, such as London Black.
Each material has specific characteristics regarding appearance, installation, and long-term care. Consider how each option aligns with the desired aesthetic, budget, and maintenance expectations for your Annapolis renovation project.
Integrating with Rainscreen Assemblies
For optimal performance, especially in climates with varying weather, consider integrating your new siding or cladding with a rainscreen assembly. A rainscreen system creates a ventilated air cavity between the exterior cladding and the wall sheathing. This cavity allows moisture to drain and air to circulate, promoting drying and reducing the risk of moisture-related issues within the wall structure.
Many siding and cladding options, including thermally modified wood, are well-suited for rainscreen applications. This approach helps manage bulk water, enhances thermal performance, and can extend the lifespan of the facade. Proper detailing around openings and transitions is critical for the effectiveness of a rainscreen system.
Considering Profiles and Dimensions
The profile and dimensions of your chosen siding or cladding material significantly impact the final appearance and installation method. Lumber Plus offers a variety of profiles that can create different shadow lines and visual textures on a facade. For example, some profiles provide a featherweight board appearance for razor-straight facades, while others offer a bold grain for impactful walls.
When planning, consider how the chosen profile will complement the architectural style of the home and how it will interact with existing features like windows and doors. The dimensions of the boards will also influence the layout and the number of cuts required during installation. Lumber Plus offers milling services to achieve specific profiles and dimensions.
Hypothetical Renovation Example: A Colonial Revival Facade
Consider a two-story Colonial Revival home in Annapolis with an existing facade measuring 30 feet wide by 20 feet high, excluding gables and openings. The current siding is aged clapboard, and the owners desire a more durable, low-maintenance solution that maintains a classic aesthetic. They choose a thermally modified Ayous cladding with a traditional lap profile.
The total wall area is 30 ft * 20 ft = 600 square feet. Assuming a conservative 10% waste factor for cuts and errors, and accounting for windows and doors totaling 100 square feet, the net area to cover is 500 square feet. With a 6-inch exposure for the lap profile, each linear foot of cladding covers 0.5 square feet. Therefore, approximately 1000 linear feet of cladding would be needed (500 sq ft / 0.5 sq ft/linear ft). To ensure enough material for field cuts and potential damage, ordering around 1100-1200 linear feet would be prudent. This calculation is a starting point; actual quantities depend on specific board lengths, window/door layouts, and desired offcut utilization.
Before you order
- Have existing wall conditions been thoroughly inspected for structural integrity, moisture, and rot?
- Is the current wall assembly documented, including sheathing, insulation, and vapor barriers?
- What are the local building codes and historical district requirements (if applicable) for facade renovations?
- Which siding/cladding material best suits the desired aesthetic, durability, and maintenance level?
- Will a rainscreen assembly be incorporated to improve moisture management and thermal performance?
- What profiles and dimensions are suitable for the architectural style and installation method?
- How will transitions around windows, doors, and corners be detailed?
- Have quantities been estimated, accounting for waste, specific board lengths, and cut plans?
- Are there any specific manufacturer installation requirements for the chosen material?
- What are the long-term maintenance expectations for the selected siding or cladding?
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 thermally modified wood?
Thermally modified wood is wood that has been heated to high temperatures in an oxygen-free environment. This process alters the wood's cellular structure, enhancing its stability, durability, and resistance to decay and insects. It is a suitable option for exterior siding and cladding applications due to its improved performance against environmental factors.
How does Norx composite cladding compare to natural wood?
Norx composite cladding, unlike natural wood, is engineered from a blend of materials, often including wood fibers and plastics. It is designed for low maintenance, consistent appearance, and resistance to rot, warping, and insect damage. While it may not offer the unique grain patterns of natural wood, it provides a durable and consistent alternative with minimal upkeep requirements.
Is a rainscreen assembly always necessary for siding and cladding?
While not always strictly required by code for all applications, a rainscreen assembly is highly recommended for most exterior siding and cladding projects, especially in climates with significant rainfall or humidity. It significantly improves the wall's ability to manage moisture, prevents water intrusion, and promotes drying, thereby extending the lifespan of the facade and enhancing the overall performance of the building envelope.
