About an hour and a half from our shop in Baxter. Moisture readings, photographs of your crawlspace and a written estimate that lists every part separately.
What we find under houses in Tullahoma
Tullahoma sits on the sandy Highland Rim soils of Coffee County, which drain better than the clay you find a few miles away and change what a crawlspace problem looks like. Standing water is less common here. What we find instead is a soil surface that is slightly damp all the time and a crawlspace full of humid air, and that is the version of the problem that does the quiet damage, because there is nothing dramatic for a homeowner to notice until the framing tells them.
Housing in Tullahoma spans the mid-century growth that came with the base and the university work, plus a good deal of newer building around Normandy Lake and out toward the highway. The mid-century houses tend to sit on low, vented crawlspaces where clearance is tight and the ductwork runs through the middle of the space. Ductwork in humid air is where condensation shows first, and a sweating duct trunk dripping onto the soil below it is a self-feeding cycle.
The emphasis on a Tullahoma job is on the seal and on humidity control, with drainage where the readings justify it. The reinforced liner covers the graded soil and runs up the walls, seams sealed and every pier and penetration terminated properly. Vents close, which is what stops warm outside air being pulled into the coolest cavity in the house, and a dehumidifier sized to the volume holds the space through the summer. Any framing or ductwork already damaged gets dealt with before we close the space up.
Everything we do in Tullahoma- Musty odors in closets, hallways or on the first floor
- High humidity, so the house feels damp with the AC running
- Mold growth on joists, subfloor or ductwork
- Standing water after rain, or ground that never dries out
- Sagging floors, often the first structural consequence
- Allergy symptoms that ease when you leave the house
None of that is a diagnosis of your house. What your home actually needs comes from the assessment and the measured scan on your own crawlspace.
The same checklist on every Tullahoma job
Every crawlspace encapsulation we do in Tullahoma, TN follows the same sequence. A liner laid over wet ground traps the problem underneath it. Groundwater comes first, then the seal, then humidity control, and your estimate lists each piece separately.
Clean-out & prep
Debris, old failed plastic and construction leftovers come out. We grade the soil surface so the liner sits flat and drains where it should.
Groundwater control
Where water enters, interior drainage and a sealed sump move it out before anything gets sealed over. Grading and downspout problems get flagged in the report.
Heavy-duty vapor barrier
Reinforced liner across the floor and up the walls, seams sealed, terminated and fastened around every pier and penetration.
Vents & penetrations sealed
Closing the vents is what stops humid outside air from being pulled in. Plumbing, wiring and duct penetrations get sealed at the same time.
Dehumidification
A sealed space still needs its humidity managed through a Tennessee August. We size the unit to the volume and hard-plumb the condensate.
Structural repairs first
Rotted posts, damaged joists or a sagging floor get addressed before the space is closed up. No one wants to reopen a finished crawlspace.
Four steps, and you see the findings before the price
Free assessment
We go under the house, take moisture readings, elevations and measurements, and check every support. Takes as long as it takes.
Findings & written estimate
Photos and readings walked through with you, then a line-item price. Financing options if you want them.
Install
The same family crew that quoted the job does the work. Most crawlspace and waterproofing projects run 1–3 days.
Annual service call
$250 a year covers a service on the equipment we installed and a fresh FoundationScan® report, so changes are caught early. No contract required.
Tullahoma questions we get asked
Nothing under our house looks wet, so why would we need this?
Sandy Coffee County soil drains well, so standing water is uncommon here and the problem is chronic humidity instead. The ground stays slightly damp all the time and the air under the floor stays high, and that is enough to soften framing over years. The moisture readings at the assessment will show you the number.
There's water dripping off the ductwork in the summer. Is that a leak?
Usually it is condensation. Cool metal in humid crawlspace air behaves like a glass of iced tea on a porch, and the water that forms drips onto the soil and keeps the space damp. Sealing the crawlspace and lowering the humidity stops it, and we look at the duct insulation while we are down there.
Our crawlspace is really low and the ducts sit right on the dirt. Can that be changed?
Yes, and it should be. Ductwork lying on damp ground stays wet on its underside and keeps the soil under it wet in turn. We lift and support duct runs clear of the ground as part of the work where clearance allows it.
How do you decide what size dehumidifier goes in?
By the volume of the sealed space and how much moisture is coming into it. An undersized unit runs constantly and never gets ahead in August, so we size it to the actual cubic footage and hard-plumb the condensate so nothing needs emptying.
Is there a scan or report we get at the end?
Yes. Every job we do comes with a FoundationScan® report, which is a measured survey of your floor. It gives you a baseline, and if you stay on the annual service call it gets re-run each year so any change shows up.
