The recommended PSI (pounds per square inch) for cleaning vinyl siding can vary, so it's best to consult the manufacturer's guidelines. Generally, vinyl siding can handle high pressure, from 2,500 to 3,500 PSI. For comparison, more delicate materials like wood and aluminum siding should not face more than 1,500 PSI. To safely disperse the pressure on vinyl, use a tip with a wider spray span, such as a green (25-degree) or yellow (15-degree) nozzle. For routine cleaning of light dirt, a garden hose with a spray nozzle may be sufficient. Always exercise caution to avoid using excessive pressure that could damage the siding.

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.

Stucco is considered a type of cladding because it includes a built-in ventilation layer, a weatherproof membrane beneath that, and, often, a layer of insulation to improve building efficiency. The multiple layers of stucco—the scratch coat, the brown coat, and the finish coat—also create a more complex building membrane, so it’s more accurate to call it cladding. However, homeowners and contractors alike refer to stucco as siding.

There are several highly durable types of siding that you can build right on top of without removing it, with wood being one of them, provided it's in excellent condition. However, a common reason for siding replacement is to eliminate materials that are in poor condition, making installing new wood siding over old not recommended. Additionally, the cost of adding siding over existing siding can increase costs to between $7 and $13 per square foot.
