On a Duncan job, crawl Space Mold Remediation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
There is growth on the joists or subfloor, and a smell coming up into the house.
Mold remediation on piedmont and upstate ground
In Duncan the pattern is usually a wet spell that never fully dried. Clay holds water against the foundation after each storm, and an enclosed space over damp ground stays in range long enough for growth to establish on the joists.
Piedmont clay is what this work is dealing with in Duncan. Clay turns water away rather than absorbing it, so water arrives at the foundation from uphill and then sits against it for days.

Why it is worth dealing with now
Left alone, a wet Duncan crawl space does not stabilise — it keeps feeding moisture into the floor structure until something upstairs gives.

Mold remediation in Duncan: common questions
Can growth under the floor affect the air upstairs?
It can. Air moves upward through a house and draws crawl space air into the rooms above through gaps around pipes and ducts, which is why a Duncan homeowner usually notices the smell in a hallway before they see anything.
Will it come back after remediation in my Duncan home?
Not if the moisture is corrected, and very likely if it is not. Around Duncan the conditions that produced it are seasonal and recurring, so the humidity control is the durable half of the job.
Do you work outside Duncan itself?
Yes. We cover Spartanburg County broadly, including Lyman, Wellford and Startex, and the rest of the Piedmont and Upstate of South Carolina.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Duncan call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Duncan property changes that.
Does mold under the floor affect the air in the house?
It can. Air tends to move upward through a house, pulling crawl space air into the rooms above through gaps around pipes, ducts and other floor penetrations. That is the usual reason a crawl space problem is first noticed as a smell upstairs rather than below.
