These codes may dictate the type of vinyl siding allowed, the installation methods, and even the required permits.
Contact your local building department to obtain any necessary permits for your vinyl siding installation. This ensures your project complies with local regulations and avoids potential fines or delays.
Remove Existing Siding, Fascia, and Soffit Materials: Before installing new vinyl siding, you'll need to remove any existing siding, fascia, and soffit materials. This step is essential for a fresh start and to ensure proper installation of the new siding.
Start by carefully removing the existing siding panels, taking care not to damage the underlying sheathing or wall structure. Once the siding is removed, inspect the sheathing for any damage, rot, or moisture problems. Repair or replace any damaged areas before proceeding with the new siding installation.
Prepare the Exterior Walls: The exterior walls of your home should be prepared for the vinyl siding installation. This involves removing any loose or damaged trim, patching any holes or cracks, and ensuring the surface is smooth and level.
If the walls are uneven, you may need to install furring strips to create a level surface for the siding. Furring strips are thin strips of wood that are attached to the existing wall framing, creating a new, level surface for the vinyl siding to be installed on.

Step 2: Installing the Sheathing

Sheathing is a crucial component of the vinyl siding installation process. It acts as a structural layer that provides a stable base for the siding panels and helps to prevent moisture penetration. The most common types of sheathing used for vinyl siding installation include plywood and oriented strand board (OSB).

Choose the Right Sheathing: Plywood and OSB are both suitable materials for sheathing, but each has its own advantages and disadvantages. Plywood is known for its strength and durability, while OSB is more affordable and easier to work with.
Consider factors such as your budget, the climate in your area, and the specific requirements of your local building codes when choosing the appropriate sheathing for your project.
Install the Sheathing: Once you've chosen the sheathing material, it's time to install it to the exterior walls. Start by attaching the sheathing panels to the wall framing using nails or screws. Ensure that the sheathing panels are installed flush with each other and that the joints are staggered to create a strong and stable surface.
Use a level and measuring tape to ensure that the sheathing is installed straight and plumb. This will help to ensure that the vinyl siding is installed evenly and looks its best.
Secure the Sheathing: After installing the sheathing panels, it's important to secure them to the wall framing. Use nails or screws that are long enough to penetrate through the sheathing and into the wall framing. The nails or screws should be spaced according to the manufacturer's recommendations.
Use a nail gun or a drill driver to make the installation process faster and easier. Ensure that the nails or screws are driven straight and flush with the sheathing surface. This will prevent them from protruding and damaging the vinyl siding panels.
