Exterior house cleaning involves the removal of dirt, grime, and other debris from the outside surfaces of a home. This process typically includes cleaning walls, windows, roofs, and driveways. Common methods used are pressure washing and hand scrubbing, which help maintain the home's appearance and prevent damage from mold or mildew. Regular exterior cleaning can enhance curb appeal and increase property value. It is often recommended to schedule this maintenance at least once a year, depending on the local environment and weather conditions. Tools like pressure washers and soft brushes are commonly used to achieve effective results.
