WDI Inspection in Charleston, SC
CL-100 Reports for Charleston Home Sales, Buyers & Sellers
In South Carolina, most mortgage lenders won’t finance a property without a CL-100 report, officially the Official South Carolina Wood Infestation Report. This document covers every wood-destroying organism a licensed inspector can identify, and it must be completed no more than 30 days before closing. The standard South Carolina Association of Realtors contract includes a contingency clause tied to it. If you’re buying, selling, or refinancing in the Charleston area, you need this report done right and done fast.
Core Pest Solutions is a family-owned, locally operated pest control company with decades of combined industry experience serving the Charleston metro area. We know the pest pressures specific to Charleston County, from Formosan termite colonies in the Lowcountry’s older neighborhoods to moisture-driven wood decay in pier-and-beam crawl spaces. When a report comes back with findings, we can handle treatment through the same team, so you’re not scrambling to coordinate a separate contractor in the middle of a closing timeline.

A CL-100 inspection is time-sensitive by nature. Delays can affect deals. Our same-day and emergency scheduling options exist specifically for situations where the closing window is tight and the inspection can’t wait. We’ve built a strong reputation across the Charleston community, reflected in our multiple five-star reviews, because we respond when it matters.
Being locally owned means our familiarity with Charleston County’s neighborhoods runs deep. We understand which construction types carry elevated risk, which soil conditions accelerate subterranean termite activity, and which parts of the Lowcountry see the most Formosan termite pressure. That local knowledge shapes every inspection we complete.
There’s also a practical advantage to using one provider for both inspection and treatment. If our report identifies active infestations or conducive conditions, we can move directly to remediation without the delay of bringing in a second company. Every service starts with a free inspection, and we offer online coupons and specials to help manage costs along the way.

What the CL-100 Covers
The CL-100 is broader than a standard termite inspection. South Carolina’s form, regulated by Clemson University’s Department of Pesticide Regulation, addresses every wood-destroying organism and related structural risk factor visible at the time of inspection. That scope sets it apart from WDI forms used in many other states.
Organisms the Report Addresses
The CL-100 covers a wider range of wood-destroying organisms than many buyers and sellers expect:
- Subterranean termites, including Formosan termites, which are particularly aggressive in coastal South Carolina
- Drywood termites
- Carpenter ants and carpenter bees
- Powder post beetles and old house borers
- Wood decay fungi, which thrive in the Lowcountry’s high-humidity environment
Beyond organisms, the CL-100 requires moisture meter readings in crawl spaces and substructure areas. The inspector also documents conducive conditions: wood-to-soil contact, standing water, poor drainage, and excessive moisture that put the structure at heightened risk. The report records the presence or absence of active or past infestations, visible damage, evidence of prior treatments, and those underlying conditions.
One important clarification: the CL-100 documents visible conditions at the time of inspection. Areas behind walls, under floors, and other inaccessible spaces fall outside its scope. The report is not a warranty.
How the Inspection Process Works
Our inspector conducts a thorough visual examination of all readily accessible interior and exterior areas of the structure, including crawl spaces, attics, foundation walls, and exposed wood. We look for live insects, termite shelter tubes, mud tubes, wings, dead insects, hollow or damaged wood, and signs of prior treatment activity.
After the on-site assessment, findings are compiled into the Official South Carolina Wood Infestation Report. The report is valid for 30 days in South Carolina. If closing is delayed past that window, a new inspection is required before the lender can proceed.
If the report isn’t clear, the mortgage lender will typically pause the loan process until documented issues are treated and conducive conditions corrected. Under the standard South Carolina contract, the seller is generally responsible for treating any active infestation the report identifies. Once remediation is complete and documented, a re-inspection can confirm the issues have been addressed so the transaction can move forward.
Why WDI Risk Is Elevated Across Charleston County
Charleston’s warm, humid coastal climate creates favorable conditions for subterranean and Formosan termites year-round. Formosan termites are considerably more aggressive than native species and can cause severe structural damage in a shorter time frame. In the Lowcountry, they’re not a remote risk. They’re a documented local pressure.
The region’s concentration of historic homes, waterfront properties, and pier-and-beam construction with crawl spaces compounds that risk. Wood-to-soil contact, moisture accumulation, and wood decay fungi appear frequently in Charleston County inspection reports, a direct reflection of the area’s humidity levels and building stock. Newer construction isn’t immune: poor drainage, wood-to-ground contact, or a plumbing leak can create the same conducive conditions regardless of a home’s age.
As a locally owned company, Core Pest Solutions has direct familiarity with these conditions across Charleston County neighborhoods. We offer pest-specific solutions that target the organisms most common to this area, along with quarterly follow-up services and seasonal treatments for ongoing protection well beyond the inspection itself.
