Slab-on-grade homes have no sub-floor to inspect, so the work moves to the slab edge, the penetrations and the perimeter.

A slab-on-grade home sits directly on a concrete slab, so there is no crawl space or sub-floor to walk. A technician inspects the slab edge, the penetrations where pipes and wires enter, the expansion joints and the perimeter, and treats the soil and landscaping that touch the foundation.
A large part of the newer housing on the edges of North Charleston is slab-on-grade, including the post-1995 communities around Cane Bay, Nexton, Carolina Park, Crowfield and the 29420 ZIP code. A mid-century house gives a technician open framing to check. A slab house gives a continuous floor and a foundation edge, so most of the evidence sits at the outside of the house.
The method changes. A crawl space can be walked, so a technician can follow a termite tunnel or moisture problem to its source. On a slab the same problem is traced from outside: the perimeter, the points where pipes and wires pass through the concrete, and the joints between slab and wall. A homeowner should not assume the crawl-space approach carries over.
Local pests change their pattern on a slab. Fire ants arrive with new landscaping and turf, since soil, sod and nursery stock move under federal quarantine rules that cover the whole state. Clemson Extension notes that rats can damage slabs and foundations within months. See fire ant control for the new-turf side.
The inspection starts at the outside of the foundation and works inward. The technician checks the slab edge, the wall-to-slab joint, utility penetrations, thresholds, and the landscaping and irrigation touching the foundation.
The technician walks the full perimeter looking for cracks, gaps, failed caulk and openings where utilities enter the slab or wall. Penetrations for water, gas, electrical and cable lines are common gaps, and each is noted. Garage and entry thresholds get the same attention, since they are where concrete meets the living area.
Landscaping comes next. New beds, mulch and turf often sit against the foundation, creating a path for insects and moisture to the wall. The technician checks how close the planting is, whether irrigation sprays the foundation and whether any wood touches the slab.
Yes. A slab removes the sub-floor, but subterranean termites can still reach the structure through the perimeter, utility penetrations and any wood in contact with soil or the foundation.
The common assumption that a slab is immune is not a safe one. Subterranean species work from the soil, and a slab does not block them at an opening in the perimeter or a penetration through the concrete. Clemson's guidance notes the Formosan species is established along the coast, so the risk does not depend on a crawl space.
On a slab the technician checks for tubes or tunnels on the exterior of the foundation, wood in contact with soil, and any damage where wall framing meets the slab edge. It is a different check from a sub-floor inspection, but it is still a termite inspection.
New subdivisions bring in soil, sod and young plants, and South Carolina is inside the federal fire ant quarantine zone, so those materials are regulated. A technician can explain how fire ants reach a new yard.
Clemson's Department of Plant Industry states that South Carolina is entirely within the federal imported fire ant quarantine zone. Soil, hay, nursery stock, sod and soil-moving equipment are regulated articles, which helps explain why fire ants appear in new turf and landscaping.
This page does not claim that any company handles quarantine compliance. The practical point is that new turf or landscaping is a route into the yard, and beds set against the foundation bring that landscaping close to the slab.
No price is published on this site. Perimeter length, penetrations, landscaping, scope and sale-related reports all change the work. The price is explained and approved on site before any work starts.
The size and footprint of the house come first. A longer perimeter means more edge to check, and an attached garage or second structure adds to the scope. Each utility penetration needs a look, and access is harder where fences, decks or landscaping block the path around the foundation.
A spot treatment at one entry point is a different job from a full perimeter plan, and a homeowner who wants landscaping, turf and penetrations covered should expect a broader scope. A CL-100 for a sale is a separate inspection that changes the visit. Work does not begin until the price has been explained.
A plan is set after the perimeter, penetrations and landscaping are checked. Follow-up matters because outdoor conditions change through the year, and the technician explains what to watch for between visits.
The scope comes from what is found: which perimeter sections need work, which penetrations need sealing or treatment, and which landscaping should move back. The plan is explained in plain terms, including what the work will and will not reach.
Between visits the homeowner keeps the edge clear, checks penetrations after storms and watches for soil tubes or winged insects near the slab. With no winter kill on this coast, pest activity does not pause for the cold, so a year-round plan fits better than a single visit.
Do not seal the slab edge, penetrations or joints with store products before a technician has seen them, since a sealed gap can hide activity. Do not dig into the slab or cut concrete to reach a suspected problem. Keep mulch, soil and beds pulled back from the foundation, and keep wood out of contact with the slab edge. Call (855) 974-4733 for a technician if a fire ant mound or trail appears in new turf.
The first step is to confirm the house sits on a slab, and to note the subdivision's age and whether any crawl space exists. A caller can describe the floor and the entry steps, which usually settles the question.
The technician walks the full perimeter, checking the slab edge, the wall-to-slab joint, cracks and open gaps. Each opening is noted with its location and shared with the homeowner.
Utility penetrations, garage thresholds and entry steps get a close look where the concrete meets the house. The condition of each one and any sign of activity are recorded.
Mulch, beds, turf and irrigation are checked for distance from the foundation and for water running toward the slab. Findings are explained in terms the homeowner can act on, such as which bed to move back.
The scope is set from what was found and explained before work starts. The technician sets a recheck interval that runs through the year, since there is no winter break in pest activity here.
Where the edge, penetrations and landscaping show little, the technician documents the perimeter check and explains what was looked at. The plan may be light, with follow-up at an agreed interval, and the homeowner keeps the edge clear between visits.
Gaps at utility lines, thresholds and joints are recorded, and the technician explains which are likely pest routes and which are cosmetic. Sealing and treatment decisions are made with the homeowner after the findings are shown.
New beds, mulch and turf set against the foundation bring planting into direct contact with the edge. The technician explains how close it sits, what can be moved back, and whether irrigation sprays the wall.

The slab stock is concentrated in newer bands, including Cane Bay, Nexton, Carolina Park and Park West, Crowfield and the 29420 ZIP code. These master-planned communities have stormwater ponds, young planted landscaping and new turf, and each feature changes what a technician sees at the foundation.
Recent slab construction also appears around Summerville and Moncks Corner. The climate does not change at the city's edge, so the same year-round pressure applies. A homeowner in a newer subdivision should expect a perimeter-first inspection wherever the slab is.
Some of these sites are low and sandy, with tidal creek and marsh edge nearby, and drainage is poor in places. A technician notices where water sits after rain and where grading carries it toward the slab, since moisture at the foundation draws insects to the same edge being inspected.

A vented crawl space in coastal South Carolina can hold more moisture than its vents suggest.
Yes. Subterranean termites can reach a slab through the perimeter, utility penetrations and any wood touching soil or the foundation. A technician inspects the outside edge and the framing where it meets the slab, then reports what is found.
It is a house built directly on a concrete slab, with no crawl space or sub-floor under the living area. Many newer homes in the area are built this way, especially in the post-1995 subdivisions, so the inspection starts at the perimeter.
South Carolina sits entirely within the federal fire ant quarantine zone, and soil, sod and nursery stock are regulated articles. New turf and landscaping bring those materials into a yard, which is one route for fire ants. The fire ant page covers mounds and treatment.
They can. Clemson Extension notes that rats can damage concrete slabs and foundations within months, so the slab edge and wall openings matter. Exclusion matters more than bait, so a technician looks for entry points on the outside first.
This site does not publish prices. Perimeter size, penetrations, landscaping, scope and any sale-related reports change the work. The price is explained and approved on site before any work starts.
Pulling mulch, soil and beds back from the foundation is a sensible step, since it gives insects and moisture less of a path to the wall. A technician can show where planting sits close to the edge, and that advice is worth getting before beds are dug out.
