There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

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.

If you have stucco on the outside of your home, it’s technically considered cladding and not siding, but beyond that, it’s impossible to tell without a little digging. Without damaging the siding material, expose part of it to see if there’s an air gap between the siding and your exterior wall. If there is, you have cladding. If the siding is affixed directly to the exterior wall, you have a simple siding system.

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.
