Older Home in Southern California? Termite Risk Accumulates Over Decades

Homes built in the 1950s–1970s typically have original wood framing that has never been treated for termites. Over decades, drywood colonies can become established in attic framing, window headers, and sill plates — often multiple generations of colonies across different areas.

Older construction methods create more termite entry points. Lap siding over felt paper (rather than modern house wrap), wood-to-soil contact at porch steps and planters, unsealed attic vents, and wood shake roofing all provide entry points that modern construction minimizes.

The cumulative nature of termite damage in older homes means that addressing one area may reveal previously unknown damage adjacent to it. Our inspectors document all findings — active infestation, old damage, and conducive conditions — in a comprehensive written report.

For older homes with multiple active infestation sites, tent fumigation often provides the most cost-effective whole-structure treatment. Addressing multiple spot-treatment sites individually can exceed fumigation cost while missing hidden gallery systems.

Annual inspections are particularly important for pre-1980 homes. Catching new activity early — before it spreads from fascia into attic framing, for example — is far more cost-effective than treating widespread infestation.
