What does a termite inspection in Merrillville, IN actually involve?
A termite inspection in Merrillville is a visual examination of your home's accessible structure — foundation, crawl space, basement, attic framing, and wood-to-soil contact points — conducted by a certified inspector looking for live wood-destroying insects, evidence of past activity, and conditions that invite future infestation. The whole process typically takes 45 to 90 minutes depending on home size.
What is the NPMA-33 report and why does my lender require it?
The NPMA-33 is the nationally standardized Wood Destroying Insect (WDI) inspection report required by most mortgage lenders before closing. It documents evidence of termites, carpenter ants, carpenter bees, and re-infesting wood-boring beetles found during the inspection. Without a completed, signed NPMA-33 from a certified inspector, many FHA and VA loans cannot fund — so this report is a hard requirement, not a formality.
How do I know if I actually have termites or just wood rot?
An experienced inspector can tell the difference on sight. Termite damage leaves hollow-sounding wood, mud tubes along foundation walls, and a distinctive grain pattern where insects have eaten along the grain. Wood rot softens and discolors differently and usually points to a moisture problem, not an infestation. Both conditions need attention, but the fix — and the urgency — are completely different.
The rest of this guide walks through exactly what happens during a WDI inspection in Merrillville, what the NPMA-33 report tells you (and what it doesn't), and what to do when the report comes back with findings.
What a WDI Inspector Checks — Room by Room
- Foundation and sill plates: Where wood meets concrete is the #1 entry point for subterranean termites common in Lake County.
- Crawl spaces and basements: Dark, humid, and often unfinished — the preferred nesting environment.
- Garage framing: Often overlooked by homeowners; wood framing near soil is vulnerable.
- Attic framing and rafters: Drywood termites work top-down; an inspector checks here too.
- Exterior wood trim, decks, and fences: Any untreated wood with ground contact is a risk point.
- Window and door frames: Settlement gaps create entry points that termites exploit quickly.
Why Merrillville homes are particularly worth inspecting
Merrillville sits in Lake County, Indiana — an area with a mix of older ranch homes, post-war construction, and newer subdivisions built on former farmland. Subterranean termites are the dominant species throughout Northwest Indiana, and they're well-established in the clay-heavy soils common across the region. According to the Purdue Extension — Lake County, Indiana's climate and soil conditions create favorable environments for subterranean termite activity across the northern counties.
Older homes along the US-30 corridor often have original wood framing with decades of exposure. Newer homes in subdivisions near I-65 can still be at risk if landscaping mulch, wood debris, or grade issues create soil-to-wood contact. No construction era is immune.
Indiana's freeze-thaw cycles also matter. When foundation walls shift slightly over years of winter heaving, small gaps open up — and termites don't need more than 1/32 of an inch to find their way in. A thorough Termite Inspection catches those entry conditions before they become structural damage.
What does the NPMA-33 report actually say?
The NPMA-33 is a one-page standardized form, but what it communicates is specific and legally significant. The National Pest Management Association (NPMA) developed and maintains the form to ensure consistency across every WDI inspection in the country — which is exactly why lenders trust it. Here's what it covers:
- Section 1 — Evidence of wood-destroying insects: The inspector checks "yes" or "no" for each of the four regulated insect types (subterranean termites, drywood termites, carpenter ants, wood-boring beetles). Any "yes" triggers a description of where evidence was found.
- Section 2 — Evidence of previous treatment: Notes whether the home has been treated before, which matters to buyers and lenders.
- Section 3 — Conditions conducive to infestation: This is where inspectors flag things like wood-to-soil contact, excessive moisture, or inaccessible areas that couldn't be examined.
- Inspector signature and certification: Only a certified WDI inspector can sign and issue a valid NPMA-33. This is not a form a general home inspector can complete without that specific certification.
At Hawk Home Inspection, our team issues official NPMA-33 WDI reports accepted by lenders — the same reports your real estate agent and closing attorney need to move the transaction forward.
NPMA-33 vs. a General Inspection: What's the Difference?
| Factor | NPMA-33 WDI Inspection | General Home Inspection Only |
|---|---|---|
| Lender accepted | Yes — required for FHA/VA loans | No — cannot satisfy lender requirement |
| Inspector certification | Certified WDI inspector required | General home inspector certification |
| Scope | Wood-destroying insects + conducive conditions | Whole-home systems and structure |
| Report format | Standardized NPMA-33 form | Narrative report with photos |
| Best used for | Closings, pre-listing, peace of mind | Overall property condition assessment |
- Lender accepted: NPMA-33 yes — general inspection alone, no.
- Certification: WDI inspection requires a specific WDI certification; general inspection does not cover this.
- Scope: WDI focuses on wood-destroying insects and conducive conditions; a general inspection covers the whole home.
- Best pairing: Order both together — Hawk offers all eight services under one company, so one call covers everything.
Many buyers order both a Residential Inspection and a WDI inspection at the same time. Scheduling them together saves a trip and means you get all your findings in one plain-English digital report with photos — delivered the same day.
What happens if the NPMA-33 comes back with findings?
A positive finding doesn't automatically kill a deal. It opens a conversation. Here's the typical path:
- Review the finding location and severity. Evidence in an accessible crawl space is very different from active infestation in structural beams.
- Get a treatment estimate from a licensed pest control company. The inspection report tells you what's there; a pest control company tells you what it costs to fix.
- Negotiate with the seller or adjust your offer. Buyers can request the seller treat the home before closing, or adjust the purchase price to reflect the remediation cost.
- Re-inspect after treatment if required by the lender. Some lenders want a clearance letter or updated NPMA-33 confirming the treatment was completed.
Our inspectors walk you through every finding in plain language — no guesswork, no alarming technical jargon. You leave knowing exactly what was found and where. If you want to attend the inspection in person, we encourage it. Walk the property with us and ask questions as we go.
Pair your WDI inspection with a Commercial Inspection if you're purchasing investment property or a mixed-use building in Merrillville — the same thorough approach applies, and the NPMA-33 satisfies most commercial lenders too.

Frequently Asked Questions
How long does a WDI inspection take in Merrillville?
Most WDI inspections in Merrillville take between 45 and 90 minutes, depending on the size and accessibility of the home. Larger homes with full basements, crawl spaces, and finished attics take longer because there's more structure to examine. You'll receive your completed NPMA-33 report the same day, delivered digitally with photos of any findings or conditions noted.
Do I need a separate inspector for termites and a general home inspection?
Not with Hawk Home Inspection. We offer both a full Residential Inspection and a certified WDI inspection under one company. You can schedule both for the same day, which is the most efficient approach at closing time. You'll get two separate reports — the narrative home inspection report and the official NPMA-33 — delivered together.
Is the NPMA-33 required for conventional loans, or only FHA and VA?
FHA and VA loans almost always require an NPMA-33 before funding. Conventional loans vary by lender — some require it, some don't. Your lender or real estate agent will confirm the requirement for your specific transaction. When in doubt, ordering the WDI inspection is inexpensive insurance against a last-minute closing delay if the lender asks for it after the fact.
Can I get a termite inspection if I'm not buying or selling — just for peace of mind?
Absolutely. Homeowners in Lake County order WDI inspections for peace of mind all the time, especially after seeing a neighbor's home treated or after noticing something suspicious in a crawl space or garage. There's no lender or transaction required — an inspection is an inspection. Call (219) 730-5463 and we'll set it up at a time that works for you.
What other inspections pair well with a termite inspection in Merrillville?
The most common pairings are a full residential inspection (for overall home condition), Radon Inspection (radon levels in Lake County warrant regular testing), and Water Inspection if the home uses a private well. Hawk Home Inspection offers all eight services under one company, so you can schedule everything in a single call and get it done before your inspection contingency deadline.
