Although certain hardwoods are resistant, Termites can still cause damage depending on the condition of the hardwood, for example, moisture percentage, age, and decay. Hardwood timbers generally become more resistant due to age as the timbers will become harder over time. A Termite inspection is strongly recommended 6-12 Monthly.
