Why is a slab house treated at the edges?
A slab house has no crawl space, so the termites that reach it come through the soil at the foundation edge, the joints and the penetrations. The treatment follows those routes rather than the middle of the floor.
The concrete itself is not the main entry point for most termites. The gaps where the slab meets a wall, where a line comes through, and where a joint opens are the places a termite can use. That is why a slab inspection looks so closely at the edges and at the soil contact along the foundation.
What is the expansion joint, and why does it matter?
An expansion joint is the seam where the slab meets a wall or another part of the foundation. It can open over time, and an open joint is a route that a technician checks and records.
Joints move with the house, the soil and the weather, so a joint that was tight at one visit can be open at the next. A technician notes the condition of each joint on the diagram, which makes it easier to see whether a joint has changed.
Does brick veneer change the treatment?
Yes. Brick veneer creates a gap behind the brick and a weep line near the soil, and both points are checked and recorded as part of the treatment.
The weep line is where water is meant to drain out of the wall, and it sits close to the soil. Soil that builds up above the weep line or against the brick can carry termites to the wall, and the technician checks the soil in both directions from the line.
What moves the price up or down here?
The length of the perimeter, the number of penetrations, the amount of brick veneer, the soil conditions and whether the work is a single treatment or a contract shape the price. No figure is printed on this page, and the price is explained and approved in writing before any work starts.
A long perimeter with many penetrations takes longer to read and to treat than a simple rectangular slab. Brick veneer adds work at the weep line, and soil that sits high against the foundation can need more attention than soil that drains away.
What does a homeowner need to know about the method?
The method is chosen for each area, and the rules list the options. The homeowner should know which method was used where, and what the contract says about inspections and retreatment.
Georgia's rules list comprehensive soil, defined soil, wood treatment or fumigation, baiting and an alternate application technique for subterranean termites. On a slab, the technician explains which of those is used for each area and why. A homeowner who keeps the diagram and the contract can see the whole plan at once.
