That 1920s bungalow in Willow Glen? The Mid-Century ranch in Walnut Creek? Beautiful, timeless… and exactly the kind of home termites love.

Older Bay Area homes come with character—but also outdated construction materials, hidden moisture issues, and years of patchwork repairs that open the door for termite infestations.

At Good Sense Termite, we inspect these properties every day. We know where the weak spots hide and how to protect aging homes without gutting their charm (or your wallet).

Why Termites Target Older Structures

1. Outdated Framing and Siding Materials

Homes built before 1980 often used softer, untreated wood that’s more prone to termite attack. Redwood and Douglas Fir, while common, are vulnerable if not maintained properly.

2. Previous Repairs or Remodels Create Hidden Entry Points

We regularly find termite colonies in areas where past homeowners made DIY repairs, installed additions, or patched water damage. New wood next to old wood—especially when sealed poorly—is a hotspot.

3. Worn or Missing Vapor Barriers

Many older homes have crawlspaces without adequate vapor barriers, allowing moisture from the ground to rise and attract Subterranean termites.

4. Historic Landscaping Choices

Planter boxes built into siding, mature ivy on walls, and decades-old sprinkler systems often go unchecked—until termites show up.

Common Termite Risks in Older Homes

• Floor and roof framing that lacks pressure treatment

• Earth-to-wood contact where the grade has shifted over time

• Gaps or dry rot around original window and door frames

• Legacy utility penetrations (gas, water, HVAC) never sealed properly

• Original siding with cracks, paint failure, or moisture damage

FAQ

Are older homes guaranteed to have termites?

Not guaranteed—but statistically more likely. Many have had activity in the past, or are set up with conditions that termites love.

Can you treat older homes without damaging them?

Yes. We use localized treatments, trenching, and non-invasive methods designed for sensitive structures.

What if my home was treated before?

We’ll review prior reports and check for any reinfestation or new risk areas. If needed, we can provide supplemental treatment and warranty coverage.

Vintage homes have survived a lot—but termites can sneak in quietly and cause major damage before you notice.
