Termites tend to attack houses from underground. What most people don’t know is that termite barriers built into houses don’t actually stop termites getting in, they just make them easier to see. The barriers are inspection systems rather than prevention systems. Regular inspections use the barriers to look for termite entry at pre-determined locations. If found, they can be treated.
Regular inspections are important because avoiding them can be very expensive. For instance, household insurance doesn’t normally cover termite damage. Building insurance and warranties can also be invalidated. This means you pay for the damage.
