The exterior of your home varies in different materials from brick, to stucco, to wood, to vinyl siding. Given the climate elements from moisture to high heat, it is a best practice to inspect the outside of your home. Look for cracks, warping, separation at joints, and other anomalies. Depending on your exterior wall materials, you may need to fix or replace these areas to avoid moisture and water getting inside your walls and causing mold problems, as well as aesthetic problems that cause your home to lose re-sale value.
