WDI Inspections in NJ: What Buyers and Sellers Need to Know
If you are buying or selling a home in South Jersey, at some point someone is going to ask for a termite inspection. Your agent will mention it, your lender will require it, or it will show up on a closing checklist with an unfamiliar form number attached to it. Then the questions start. Who pays for it? What happens if they find something? Does a bad report kill the deal?
Here is what a wood destroying insect inspection actually involves in New Jersey, what the report does and does not say, and how to keep it from becoming the thing that delays your closing.
What a WDI Inspection Is
A wood destroying insect inspection, usually shortened to WDI, is a visual examination of a property for evidence of insects that damage structural wood. In practice that means four pests: subterranean termites, carpenter ants, carpenter bees, and reinfesting wood boring beetles. In older South Jersey homes, powder post beetles come up more often than most buyers expect.
The inspector walks the exterior and the accessible interior looking for mud tubes, frass, exit holes, hollowed or damaged wood, live or dead insects, and moisture staining. They also document what the industry calls conducive conditions. Those are things like wood to soil contact, excessive moisture in a crawl space, or mulch piled against siding. Conducive conditions are not an infestation. They are the circumstances that invite one, and they get noted because they affect risk.
The findings go on a standardized form called the NPMA-33, published by the National Pest Management Association. It is the same form used across the country, and it is what your lender is looking for.
Who Can Legally Perform One in New Jersey
This part trips people up. Anyone can look at a house and offer an opinion about termites. Not everyone can sign the form.
In New Jersey, the NPMA-33 must be completed by a licensed commercial pesticide applicator holding NJDEP Category 7B certification, which covers termites and other wood destroying pests. Licensing is administered by the New Jersey Department of Environmental Protection Pesticide Control Program under the state Pesticide Control Act. A general home inspector without that specific certification cannot sign the report, which is why WDI inspections are often coordinated separately from the standard home inspection even when they happen the same day.
If you are a seller lining this up yourself, ask directly whether the inspector holds 7B certification. A report signed by someone who is not certified is a report your lender will send back.
When Your Lender Requires It
Requirements vary by loan type, and this is where most of the confusion comes from.
VA loans require a WDI inspection in New Jersey, and the completed NPMA-33 has to be on file before the loan closes. FHA loans follow HUD guidance and call for one when there is visible evidence of infestation or damage, when the appraiser flags a concern, or when inspections are customary to the area. Many conventional lenders ask for a clean report as a condition of closing even though no federal rule forces them to, largely because New Jersey sits in Termite Infestation Probability Zone 2, which means moderate to heavy termite pressure across the state.
One detail worth knowing if you are using a VA loan: as of a 2022 policy change, the buyer is now permitted to pay for the inspection. Before that the cost typically fell to the seller, which occasionally complicated negotiations.
Even when nobody requires it, a WDI inspection is worth ordering. Termite damage is slow, quiet, and expensive, and it is much easier to negotiate a repair before the inspection contingency expires than to discover a problem after you own the house.
What the Report Actually Says
A common misconception is that the NPMA-33 is a pass or fail certificate. It is not. It is a factual record of what a certified inspector observed on a specific day.
The report distinguishes between a few different findings, and the distinction matters:
- Active infestation. Live insects or clear evidence of current activity. FHA and VA will not close until it is treated, and treatment is typically negotiated between buyer and seller.
- Evidence of previous infestation with no current activity. Very common in older homes. Usually closable with documentation of prior treatment.
- Structural damage. May require a repair certification before the loan will close.
- Conducive conditions only. No insects found, but conditions on the property raise the risk. Worth addressing, rarely a closing obstacle.
One thing the NPMA-33 does not include is a cost estimate for treatment or repair. That falls outside the form’s scope and requires a separate assessment. If a report comes back with findings, the next call is for a treatment quote, and that quote is what actually gets negotiated.
Sellers should also know that New Jersey’s Seller’s Property Condition Disclosure Act creates a separate obligation. If you know about a past infestation or prior treatment, that is a disclosure item regardless of what a new inspection turns up.
What Happens If They Find Something
Findings are normal. A meaningful percentage of inspected homes in South Jersey show some evidence of wood destroying insect activity, current or historical, and most of those transactions still close.
What derails a closing is not the finding itself. It is the timeline. A report comes back on a Thursday, the treatment quote takes a week, the treatment gets scheduled for the following week, and suddenly you are asking for an extension on a contract that was supposed to close Friday. The deals that go smoothly are the ones where somebody ordered the inspection early enough to absorb a surprise.
If you are selling, that argues for a pre-listing inspection. Knowing what a buyer’s inspector is going to find, before you are under contract and on a clock, puts you in a much better position. You can treat it, document it, and price it in, rather than negotiating against a deadline.
How Ross Handles WDI Inspections in South Jersey
Ross Environmental Solutions has been performing wood destroying insect inspections across South Jersey since 1992. We have four NJDEP-credentialed WDI inspectors on staff, and paperwork is available at the time of inspection rather than days later, which matters when a closing date is already set.
We work regularly with agents, buyers, and sellers throughout Gloucester County, Camden County, Burlington County, and the rest of our service area. If a report does turn up activity, we can quote and schedule termite treatment directly, so you are not chasing a second company while the contingency window closes.
For agents who handle volume, our real estate professional services are built around transaction timelines rather than general service scheduling.
The Short Version
A WDI inspection is a certified visual inspection for termites and other wood destroying insects, documented on the NPMA-33 form, and in New Jersey it has to be signed by someone holding NJDEP 7B certification. VA loans require it, FHA loans often do, and many conventional lenders want it anyway. The report is a factual record, not a pass or fail grade, and findings are common enough that they rarely kill a deal on their own.
Order it early. That is the whole trick. If you have a closing date already set and need an inspection on the calendar, call us at 1-888-399-7677.
