You cannot install clapboard siding on a bare, unprepared surface. Clapboard siding requires a clean, sturdy base made from plywood or similar materials, sometimes called backerboard. Then, it needs an underlayment or sheathing, a moisture membrane to help protect the exterior wall.

Note that sometimes clapboard siding is caulked as it’s installed for additional protection. We don’t suggest this: Caulking the siding can trap moisture inside the clapboards and lead to moisture damage over time. The siding needs some space to “breathe,” especially in rainy weather.

While vinyl is the less expensive option, composite siding has been known to be more durable than vinyl. In addition, because it is made from recycled materials, it is a more ecologically-friendly choice. Composite siding is also more luxurious looking and comes in a much wider range of styles and colors.

Yes, you can install siding over stucco, but it's crucial to ensure the stucco is in good condition first. Before proceeding, inspect the stucco for any signs of damage, leaks, or mold growth. If you discover water damage, mold, or have ongoing leak issues, it's recommended to remove the stucco completely. This step prevents future problems like mold and pest infestations and allows a professional to repair or replace any damaged sheathing underneath. If the stucco is sound, the installation process involves attaching furring strips to the wall's framing directly through the stucco. The new siding is then installed onto these furring strips. A professional may also need to adjust window and door openings to prevent them from being recessed behind the new siding, which can cause aesthetic issues and create potential leak points.

A square of siding refers to 100 square feet of siding materials. Rather than sell by the individual square foot, manufacturers typically sell siding materials by the square. For instance, if you need 105 square feet of siding but the material is sold in squares, you’ll need to purchase two squares (200 square feet).
