What You Should Know!!
A Wood Destroying Organisms (WDO) inspection is a specialized evaluation that checks for the presence of insects and organisms that can cause structural damage to wood in a home.
This typically includes termites, carpenter ants, powderpost beetles, and wood-decaying fungi. During the inspection, a licensed professional looks for visible signs of infestation, such as damaged wood, exit holes, frass (insect droppings), and moisture issues contributing to wood decay.
WDO inspections are crucial in humid climates where these organisms thrive. Identifying and addressing problems early can prevent costly repairs and preserve the home’s structural integrity. Many lenders require a WDO inspection report before approving financing for a home purchase.
For buyers and homeowners alike, this inspection is a smart step to ensure the long-term safety and value of the property.
