Termite shields are metal (aluminum or copper) barriers deflecting termites away from wood. Cost is $500-1,500 for installation. Modern construction requirement in most codes. Simple and effective prevention. Works with other termite control measures. Inspection can reveal gaps requiring sealing. Complements regular pest inspections. Does not prevent termites if improperly installed. Critical first line of defense. Particularly important in termite-prone regions.
Pro Tip
Verify termite shield presence and integrity during inspection. Gaps or damage defeat the purpose; they're inexpensive to install or repair.
