Home Buyer\'s Termite Checklist for North Bay California
What to look for, what to ask, and what your WDO report means — a practical termite guide for buyers purchasing homes in Sonoma, Marin, Napa, and Solano Counties.
Why Termites Matter More in the North Bay Than in Most of California
The North Bay\'s mild, year-round climate, high concentration of older wood-frame housing stock, and the significant humidity variations between coastal and inland communities create more consistent and widespread termite pressure than most California markets. In the North Bay, virtually every home has either current termite activity or the conditions that make future activity likely. The question for buyers is not "does this property have termites?" but "how extensive is the current situation, what has been treated, and what will treatment and repair cost?"
Step 1 — Order Your Own WDO Inspection Early
Do not rely solely on a seller-provided WDO report. Order your own independent inspection within the first week after offer acceptance — during your inspection contingency period. An independent inspection ensures you receive an unbiased assessment by an inspector working for you, not the seller. Redwood Empire conducts buyer-ordered WDO inspections throughout the North Bay with same-day report delivery.
Step 2 — Red Flags to Watch for Before the Inspection
During your walkthrough or open house visit, be alert to:
Piles of small granular pellets (termite frass) on windowsills, floors near baseboards, or in drawers of wood furniture
Small round holes (kick-out holes) in wood trim, baseboards, or furniture surfaces
Mud tubes on foundation walls visible from outside
Hollow sound when tapping door frames, window sills, or baseboards
Blistering or bubbling paint on wood surfaces without obvious moisture cause
Very old homes (pre-1950) with no disclosed termite history — absence of history does not mean absence of termites
Recently painted surfaces that may be covering active activity or damage
Step 3 — Reading Your WDO Report
When you receive your WDO report, focus on three things:
Section 1 findings: these are active infestations requiring correction — what species, where in the structure, and the estimated correction cost
Section 2 findings: these are conducive conditions — what moisture or structural conditions create elevated future risk
"Further inspection required" notations: these indicate areas the inspector could not fully assess — often inside wall cavities, behind finished surfaces, or in inaccessible attic areas. These deserve follow-up
Step 4 — Negotiating Section 1 Findings
Section 1 findings give you legitimate grounds to negotiate price, correction credit, or seller-paid correction before close. Common approaches:
Request seller-paid correction: ask the seller to complete and document all Section 1 corrections using a licensed company before close
Request a price reduction equal to estimated correction cost: gives you flexibility to choose your own contractor and timeline
Negotiate a credit: escrow holds funds for correction completed by buyer after close
Get written cost estimates from a licensed company before negotiating — you need specific numbers, not guesses.
Step 5 — After Close — Ongoing Protection
Even after Section 1 findings are corrected, establish an annual inspection schedule with your pest company. The conditions that produced the corrected infestation often persist — older construction, mature landscaping, coastal humidity — and new activity can establish. Annual professional inspection is the most cost-effective long-term protection strategy for North Bay homeowners.
Frequently Asked Questions
Yes — while new construction is less likely to have established termite infestations, it is still susceptible to drywood termites. More importantly, new construction often has conducive conditions (wood debris left in the crawl space, inadequate grading) that should be identified and corrected early.
Sellers are required to disclose known material defects, but many termite infestations are genuinely not known to the seller — particularly in attic spaces and crawl spaces that are rarely accessed. A seller\'s representation of no termite history does not substitute for a professional inspection.
This notation means the inspector found conditions suggesting possible activity in an area they could not fully access (inside a wall, behind finished surfaces). It is not necessarily an alarm — it means you should follow up with additional inspection in that area before close. We can advise on the appropriate next step for each notation.
Localized treatment for a straightforward drywood termite finding typically costs $500–$2,000. Extensive infestations requiring fumigation range from $2,000–$6,000+ for a typical home. Structural repairs add to these costs depending on extent. Getting written estimates from Redwood Empire gives you specific numbers for your negotiation.
Not necessarily — virtually all North Bay homes have or have had termite activity, and an established treatment and inspection history is not a red flag. The relevant questions are: how extensive is the current activity, what is the correction cost, and can those costs be negotiated into the purchase terms? Severe, widespread damage in an older home with no treatment history warrants more caution.
