Buying a home? Don’t overlook a WDO inspection — it could save you thousands in hidden repairs.
A WDO inspection, short for Wood-Destroying Organism inspection, identifies pests like termites, carpenter ants, and fungi that silently damage the wood structures of a home. It’s an essential step in the homebuying process, especially in pest-prone states like California and Florida.
What Does WDO Mean?
WDO stands for Wood-Destroying Organisms — pests and fungi that eat away at the structural wood in your home. These include:
- Subterranean termites
- Drywood termites
- Carpenter ants
- Powderpost beetles
- Wood-decaying fungi
These threats often work behind walls or under floors — causing serious damage before you see the signs.
What Does a WDO Inspection Consist Of?
A certified inspector examines all accessible areas of the property for:
- Active infestations or evidence of past activity
- Mud tubes, termite droppings (frass), and exit holes
- Structural wood damage or soft, hollow-sounding areas
- Moisture-prone areas like attics, crawlspaces, and basements
- Signs of fungus or wood rot
You’ll receive a formal WDO report documenting findings, concerns, and recommended treatments if needed.
✅ What WDO Inspectors Look For:
| Area Inspected | What They Check For |
| Attics & crawlspaces | Moisture, frass, wood rot |
| Baseboards & flooring | Hollow-sounding or soft wood |
| Foundation & exterior | Mud tubes, termite tunnels, water damage |
| Sheds, fences, porches | Contact with soil, signs of wood boring pests |
Is a WDO Inspection Part of a Home Inspection?
No. A WDO inspection is separate from a general home inspection.
While a standard home inspection reviews systems like HVAC, electrical, and plumbing, a WDO inspection focuses only on pest-related wood damage. Lenders—especially for VA and FHA loans—often require both inspections for loan approval.
Is a WDO Inspection Required in California?
In California, a WDO inspection is not legally required, but it’s often requested by buyers and lenders during escrow. With California’s termite-friendly climate, skipping this step can be risky.
Is a WDO Inspection Required in Florida?
Yes. In Florida, WDO inspections are commonly required, especially in transactions involving FHA, VA, or USDA loans. The state’s warm, humid environment makes it ideal for termites and fungal growth.
Who Needs a WDO Inspection?
A WDO inspection is recommended for:
- Homebuyers: To uncover hidden wood damage before closing
- Home sellers: To disclose WDO conditions and avoid deal-breakers
- Realtors: To ensure smooth transactions and prevent costly surprises
- Property managers: For ongoing pest monitoring and maintenance
- Lenders (especially VA loans): Often require WDO reports before funding
Why WDO Inspections Matter
- Hidden damage: Pests often damage areas that aren’t easily visible.
- Resale value: Pest-free homes appraise better.
- Loan approval: Lenders may require a clean WDO report.
- Peace of mind: You avoid future repairs or unexpected expenses.
What Happens After a WDO Inspection?
You’ll receive a WDO report, which may include:
- Evidence of active infestation
- Areas of concern
- Recommendations for treatment or repair
If treatment is needed, a licensed pest control company will handle remediation. Once completed, a reinspection confirms the property is pest-free.
FAQs About WDO Inspections
Q: Is a WDO inspection worth it for new homes?
Yes. Even new construction can have pest issues, especially if soil treatment was skipped or nearby structures are infested.
Q: Can I skip a WDO inspection if the home looks fine?
Looks can be deceiving. Termites often work behind walls or under floors. An inspection is your best defense.
Q: How much does a WDO inspection cost?
Costs range from $75–$200, depending on location and property size. It’s a small price to pay for major protection.
Q: Is a WDO inspection the same as a termite inspection?
A: Not exactly. A termite inspection focuses specifically on termites, while a WDO inspection includes termites and other wood-destroying organisms like carpenter ants, beetles, and wood-decaying fungi. In many states (like Florida), the terms are used interchangeably, but technically, a WDO inspection is broader.
