Pest control in Marietta › Termite control › Mableton
This page covers termite work in Mableton, where low ground, old crawlspaces and a house that has been added to over seventy years decide most of the scope. Start with the complete guide.
1 Low ground, and what it does under the floor
Mableton sits in the corner of the county where Nickajack Creek runs down to the Chattahoochee, and a fair number of its older streets are on genuinely low ground. Piedmont red clay already holds water for weeks after a storm. Put a vented crawlspace on top of clay that sits near the water table and you get a space under the floor that stays humid from one season to the next.
That is the condition eastern subterranean termites want. Georgia is Termite Infestation Probability Zone 1 nationally, and a damp Mableton crawlspace is the version of that most people here actually meet: soft joist ends near a pier, a mud tube running up a block pier to the sill, and a musty smell nobody connected to the floor until it started to give.
Crawlspace vents set close to grade make it worse, because leaf litter, mulch and regraded soil end up blocking them, and because a vent at grade lets surface water in. Before anyone treats, somebody should be looking at where the downspouts discharge, whether the grade falls away from the house, whether there is a vapor barrier on the crawlspace floor and whether it has been torn up by every trade that has been under there since 1965.
2 A house built in stages
Roughly a quarter of Mableton’s housing predates 1970, and much of it has grown since: a den added off the back on a slab, a carport enclosed, a screened porch poured against the original foundation. Each one of those is a seam. A soil treatment put down against the original footing does not automatically extend under an addition built twenty years later, and the junction between old and new is a classic route in.
It also means prior treatment history matters, and that it is usually incomplete. Products used on houses of this age before the late 1980s are no longer available and nothing applied then is protecting the house now. Ask the inspector to map the structure as it exists today rather than as it was built, and to give you the measured linear footage including every addition.

Get someone into the crawlspace
On a Mableton house, the inspection that matters happens under the floor, not on the driveway.
3 What a correct crawlspace job includes
Outside, the crew trenches against the foundation, rods down toward the footing, charges the trench with a non-repellent termiticide and backfills with treated soil. Non-repellent means the colony cannot detect it, so foragers pass through, carry it back and share it. Where concrete meets the house, they drill and inject underneath rather than skipping the section.
Underneath is the part that separates a real Mableton job from a quick one. Piers and supporting masonry get treated, interior foundation walls get treated where the structure requires it, and the technician should be probing joists and sill where tubes were found. If the crawlspace has standing water, a torn vapor barrier or blocked vents, fixing that is not an upsell bolted onto the termite job — it is the condition that will bring them back. Expect it to be written into the scope, and expect the proposal to say which sections could not be reached.
4 The bond, and why it matters more here
Mableton has unusually high owner-occupancy for this side of the county, and people stay. That makes the warranty structure the real decision. A retreatment-only bond means the company comes back and treats again at no charge, and stops there. A repair bond means they also pay to repair the wood. On a house with original floor framing over a damp crawlspace, the second one is the one that actually transfers risk.
Get the renewal schedule for the next five years in writing, and ask what happens to coverage if an annual inspection is missed. Ask about transfer to a buyer. And when you eventually sell, remember that the Official Georgia Wood Infestation Report the lender wants covers visible evidence in accessible areas only — which on a low-clearance Mableton crawlspace can leave out exactly the corner you most want someone to look at. For help comparing proposals, talk to a licensed local pro.

6 Common questions
There is standing water in my crawlspace after it rains. Is that a termite issue?
It is the termite issue. Subterranean termites need moisture, and a crawlspace that holds water gives them it year round while also softening the wood above. Treating the soil without dealing with the water usually buys you a retreatment visit rather than a result. Start with the simple things: downspout extensions, grade falling away from the house, clear vents, an intact vapor barrier.
The house was treated years ago. Does that still count?
No. The chemistries used on houses of this age decades ago are not in use any more, and a soil barrier is disturbed by every trench, addition and regrade that happens afterwards. Treat old paperwork as history, not coverage. What matters is whether there is a current bond in force, what it covers and when the last inspection was.
Does the addition on the back get treated too?
It has to be, and it is the section most often left out. An addition has its own footing, often a slab poured against the original wall, and the joint between the two is a common entry route. Make sure the measured linear footage on the proposal includes the addition’s perimeter and that any concrete poured against the house is listed for drilling.
Can I just close the crawlspace vents?
Sealing and conditioning a crawlspace can work well, but it is a system, not a switch: it needs a sealed liner, the right ground and wall detailing, and a plan for humidity. Done halfway it traps moisture rather than removing it. It also changes how an inspector reaches the structure, so talk it through with whoever holds your bond before you close anything up.
