If you're buying or selling a home in Bluffton, Hilton Head Island, Beaufort, Okatie, or Hardeeville, there's a three-letter acronym you'll want to understand before you ever sit down at the closing table: CL-100. In a region as beautiful — and as humid — as the South Carolina Lowcountry, a CL-100 inspection and a well-maintained termite bond aren't just paperwork. They're protection for one of the biggest investments you'll ever make.
As a Bluffton-based Associate Broker with Charter One Realty, I walk buyers and sellers through this exact conversation almost every week. This guide breaks down everything you need to know — in plain English — so you can move through your transaction with confidence.
What Is a CL-100 Inspection?
A CL-100, officially called the South Carolina Wood Infestation Report, is a standardized report completed by a licensed pest control professional. It documents whether a home shows evidence of termites, other wood-destroying insects, fungal decay, or the moisture conditions that invite them.
Most mortgage lenders — conventional, FHA, and VA alike — require a current CL-100 report, typically dated within 30 days of closing, before they'll fund a loan. That makes the CL-100 one of the most important (and most overlooked) documents in a South Carolina real estate closing.
Why Is a CL-100 Required in So Many SC Transactions?
South Carolina's warm, humid, coastal climate is essentially a year-round buffet for termites and other wood-destroying pests. Because the risk is so consistent here, lenders and closing attorneys treat the CL-100 as standard practice, not an optional extra. For buyers, it's a safeguard against inheriting hidden structural damage. For sellers, a clean report is a powerful trust signal that can help a listing move faster — especially in a competitive Bluffton or Hilton Head market.
What Inspectors Are Looking For
During a CL-100 inspection, a licensed pest control technician evaluates the home — including the crawl space, foundation, attic, and exterior — for:
- Active termite activity, including mud tubes
- Evidence of wood-destroying insects such as carpenter ants and powderpost beetles
- Wood-destroying fungi and rot
- Excess moisture or drainage issues that create "conducive conditions" for infestation
- Evidence of previous damage or prior repairs
If problems are found, the report notes them, and it's typically up to the seller to resolve active infestations or moisture issues before closing — anything from professional treatment to structural repair.
Common Termite Species in the Lowcountry
Not all termites are created equal, and it helps to know your opponent.
- Eastern subterranean termites are the most commonly found species across South Carolina, living in large underground colonies and causing the majority of structural termite damage nationally.
- Formosan subterranean termites, sometimes called "super termites," are an aggressive, invasive species established in Beaufort County, including Hilton Head Island. Their colonies can grow into the millions, making early detection especially important.
- Drywood termites are also found along the coast, nesting directly inside wood rather than the soil.
Why Termites Are So Common in Our Climate
Between the mild winters, high humidity, sandy soil, and proximity to marshland and waterways, the Lowcountry offers termites nearly ideal living conditions almost every month of the year. It's one of the trade-offs of our gorgeous climate — and exactly why proactive termite protection is such a normal, expected part of homeownership here, whether you're in Bluffton, Okatie, Hardeeville, or historic Beaufort.
Signs of Termite Damage to Watch For
Whether you're touring a home or maintaining your own, keep an eye out for:
- Mud tubes running along the foundation or crawl space piers
- Discarded wings near windows, doors, or light fixtures
- Wood that sounds hollow or feels soft and spongy when pressed
- Sagging floors, or doors and windows that suddenly stick
- Frass (droppings) that looks like fine sawdust or sand
- Blistered or bubbling paint on wood surfaces
A homeowner habit worth adopting: once a year, walk your crawl space, foundation, deck, and window sills and look specifically for damp or rotten wood, musty odors, and soft spots. Moisture is the single biggest invitation you can hand a termite colony — if you find wet or rotten wood, repair it as soon as possible, rather than waiting for your next annual inspection.
Understanding Termite Bonds: What's the Difference?
A termite bond is an ongoing service agreement with a licensed pest control company, covering inspection, treatment, and — depending on the bond level — repair protection.
Standard (Retreatment) Bond — Covers: re-treatment if live termites or activity are found. Does not cover: repair of any resulting structural damage. Why it matters: baseline protection that keeps chemical treatment current, but you'd be responsible for repair costs out of pocket.
Repair Bond — Covers: re-treatment plus repair of new termite damage, up to a specified dollar limit. Does not cover: pre-existing damage, moisture-related rot, or areas the inspector couldn't access. Why it matters: adds real financial protection if termites cause damage after the bond takes effect.
Repair & Reclamation Bond — Covers: re-treatment, structural repair, and reclamation or replacement of damaged wood and materials. Does not cover: damage that predates the bond, or unrelated structural/moisture issues. Why it matters: the most comprehensive tier available, offering the greatest overall protection — a smart consideration for luxury and higher-value Lowcountry homes.
Disclaimer: Coverage, terms, and dollar limits vary by pest control company. Always request and review the specific terms of an individual termite bond before relying on it.
Termite Bond Transfers: What Buyers Must Verify
Termite bonds are typically transferable to a new owner when a home changes hands, because the protection is tied to the property itself, not the person who purchased it. That said, transfer is rarely automatic. Buyers should: request a copy of the seller's current termite bond and CL-100 report; contact the pest control company directly to confirm the bond transfers and exactly what coverage applies; ask about any transfer fees or required re-inspections; confirm the transfer in writing before closing.
Buyer Tip: Never assume a bond transfers just because the seller mentions one exists. Get it confirmed, in writing, from the pest control company itself.
Why Annual Renewal Matters
An active termite bond only protects you if it stays active. Annual renewal keeps chemical treatments effective, ensures a professional revisits the crawl space and foundation to catch new activity early, and keeps your repair coverage valid.
Seller Tip: Before you list your Bluffton or Hilton Head home, order a fresh CL-100 and confirm your termite bond is current and transferable. Buyers and their agents will ask — and a clean, well-documented bond is a meaningful point in your favor at the negotiating table.
Risks of Letting a Bond Lapse
Allowing a termite bond to lapse means losing repair coverage, risking undetected termite activity between inspections, and potentially facing higher costs to reinstate coverage than if you'd simply stayed current. Structural termite damage can run into the thousands of dollars — a cost that's almost always cheaper to prevent than to repair.
The Benefits of Continuous Coverage
Staying current on your termite bond means early detection, lower lifetime costs, a smoother path when you eventually sell, and one less thing to worry about while you enjoy Lowcountry living.
Common Misconceptions
- "My home is new, so I don't need to worry about termites." New construction is not immune — termites are drawn to moisture and wood regardless of a home's age.
- "A termite bond means my home will never get termites." A bond guarantees a response and, depending on tier, repair coverage — it doesn't make a home termite-proof.
- "All termite bonds are the same." Coverage varies significantly between standard, repair, and repair & reclamation bonds.
Frequently Asked Questions
Do I need a CL-100 if I'm paying cash? Lenders require it, but it's still strongly recommended for any transaction, cash or financed, as a due-diligence safeguard.
How long is a CL-100 report valid? Most lenders require a report dated within 30 days of closing.
Can I negotiate termite repairs found during inspection? Yes — repairs, credits, or price adjustments are common and typically negotiated between buyer and seller once the CL-100 is reviewed.
Does a termite bond cover water damage or general wood rot? Typically not, unless it's directly tied to termite activity. Moisture control is generally the homeowner's responsibility.
Should I get an independent CL-100 as a buyer, even if the seller already has one? It's worth discussing with your agent — an independent report can offer additional peace of mind, especially on older homes.
