Exterior House Painting Projects. Caballero Painting Contractors team prepares the surface of your house to ensure the best paint adhesion. Contaminants such as dirt, mold and mildew, car exhaust and loose dirt can affect the quality of the exterior painting job. Pressure washing will remove most of the problem areas. However, we'll still need to scrape the remaining areas to remove any loose paint and perform any minor repairs that are needed. Lastly, we ensure that the caulking around joints and trim is in good condition. We use the highest quality exterior painting products regardless of whether your siding is aluminum or wood because it produces the best results. We can spray, brush or roll depending on the type of siding and paint to be used.
