What a typical Crawlspace Medic job runs
Your crawl space isn't sealed off from the rest of your home. It's the air you breathe.
Warm air rising through the house pulls air up out of the crawl space with it. When that space stays damp, Johnson City homeowners feel it upstairs: musty air, sticky rooms, and higher power bills.
Why Tri-Cities homeowners trust us
A specialist for some of the oldest homes in the region.
We're local and know our market: Soil across eastern Tennessee, and the Tri-Cities especially, is mostly red clay, and the houses above it in Kingsport, Bristol, and Johnson City include some of the oldest in the region. The most common thing we find underneath is extremely high moisture and relative humidity with nothing protecting the space, not even a ground barrier. Here, even a small rain can put standing water under a home, and sometimes inside it.
Crawlspace Medic works on crawl spaces and basements only, not as a side service to something else. There are no locked package options either: if all your home needs is a ground barrier, that is what we recommend.
“If a neighbor asks what I do, I say we protect your home from the ground up.”
Five things, done well.

What Johnson City Homeowners Say
Customer Reviews, in their words.
“Keith with Crawlspace Medic was outstanding from start to finish. The inspection was extremely thorough, and he took the time to explain everything he found in a way that was easy to understand. There was no pressure, no scare tactics, and no attempt to sell services we didn't need. We received detailed photos, clear recommendations, and honest answers to all of our questions. It was obvious that Keith genuinely cared about helping us make the best decision for our home. If you're looking for a company that is knowledgeable, professional, and trustworthy, I highly recommend Crawlspace Medic. The inspection alone gave us peace of mind and a much better understanding of our home's condition.”
“Keith is the kind of person you want running a business like Crawlspace Medic. Honest, dependable, and detail-oriented. He takes the time to explain things clearly, doesn't push unnecessary work, and genuinely cares about doing the job the right way. If you're looking for someone you can trust to be straightforward, show up when he says he will, and stand behind his work, Keith is your guy.”
“Keith was outstanding. From the first phone call to the final crawlthrough, everything was handled with professionalism and attention to detail. Keith stayed right on tempo, communication never missed a cue, and every part worked together in perfect harmony. Honestly, the crawlspace turned out so well that I'm half tempted to list it as additional living space and start collecting rent.”

How It Works
Simple, and on your terms.
Free inspection
The inspection costs you nothing. We read the moisture and relative humidity and see what protection is down there, which in a lot of older Tri-Cities homes turns out to be nothing at all.
We explain what we found
We walk you through the stack effect, which is a plain way of saying the air in your crawl space does not stay in your crawl space. Then you decide what makes sense for your home.
We fix the cause
Ground and wall barriers from 10 mil up to 20 mil, a Santa Fe dehumidifier, and vent sealing, sized to your house. No locked A, B, or C packages here, so if all you need is a ground barrier, that is what we quote.
A healthy home starts from the ground up
You are breathing crawl space air right now.
60% of the air you breathe inside your home comes from your crawl space. In other parts of the southeastern US you might see sand, or something closer to what people would call dirt. Here in eastern Tennessee, and in the Tri-Cities especially, it's mostly red clay. Clay doesn't move water the way sand does, so what shows up under these houses is extremely high moisture and high relative humidity. The most common thing Keith finds on an inspection is a crawl space with zero protection in place, no ground barrier, nothing at all.
The other factor is the age of the housing stock. Kingsport, Bristol, and Johnson City have some of the oldest homes in the area, and older homes are the ones most likely to have been built without any barrier under them. The warm summer months are the busiest, because that's when precipitation and humidity are both high. Even a small rain can make a big difference around here. Keith walked a house that had standing water inside a finished basement.

The Science, in One Picture
How moisture moves from the soil into your air

Effects of elevated moisture
- Mold growth
- Insect infestation
- Poor air quality
- Structural damage
Ever looked under your older East Tennessee home?
Kingsport, Bristol, and Johnson City have some of the oldest housing stock around, and this red clay holds moisture where sandier ground would not. It costs you nothing to find out, and we treat your crawl space the way you would treat the inside of your home.
The Crawlspace Medic difference
Customized scopes, not locked packages.
Ground and wall barriers at this location start at 10 mil, with 16 and 20 mil options, and the plastic carries a lifetime material warranty, a different product from the thin film that gets rolled out and forgotten. Dehumidifiers are Santa Fe, including the 70-pint model, backed by about a 6-year warranty.
Pricing lands in the honest middle. The cheapest crews cover a crawl space for $1,000 to $2,000; national foundation chains average $15,000 to $30,000; typical Crawlspace Medic work runs $6,000 to $12,000. In the Tri-Cities, a typical project on a roughly 1,500-square-foot home, with ground and wall barriers, a dehumidifier, and vent sealing, runs about $8,000 to $9,000, and choosing the 10 mil barrier can bring it closer to $7,000.
“We can tell you that really all you need here is a ground barrier. You don't need a wall barrier and all these other things to go with it.”

Pricing, compared.
How our price stacks up against the rest.
Cut-rate crews
$1,000–$2,000
A loose sheet of plastic over the problem. Fails, then gets redone on top of the damage it let happen.
Crawlspace Medic
$6,000–$12,000
The honest middle: real materials, sealed and dried, done right the first time.
National foundation chains
$15,000–$30,000
The same scope, plus the markup for a full, white-labeled system.
That $6,000–$12,000 band is where most encapsulation jobs land, not a cap. Larger crawl spaces, structural repair, or a full restoration run higher: a complete restoration on a bigger home can reach $15,000 or more. Your exact price comes from the inspection, based on size, access, and what the crawl space actually needs.
Diagnostic inspection
We measure before we recommend.
Wood moisture content between 12 and 16% is safe; over 20% means active damage is likely. Keith walks the entire space, documents it in photos, and explains what he found in plain language, including when the honest answer is that your crawl space is in good shape. The scope comes from the inspection, never from a flat price list.

What We Measure
Where your framing falls on the moisture scale
12–16% is safe. Once framing crosses 20%, active decay becomes likely, and the report shows you exactly where yours reads.
A damp crawl space doesn't stay a crawl space problem. It becomes a whole-home one.
Cupping floors, that musty smell, and rising power bills usually trace back to the same place. The good news: it's fixable, and the sooner it's caught, the less there is to undo.
Our Guarantee
No packaged systems here
“A lot of companies that do this work sell it as option A, B or C, with the price locked in and everything bundled together whether you need it or not. You can add to those packages but you can't take anything out. We build the solution around what your home actually needs, which sometimes means telling you a ground barrier is the whole job. We specialize in crawl spaces and basements rather than offering it as a side service, and full-service foundation repair such as push piers or slab leveling is not something we do.”
Conditions in Johnson City
Red clay, old houses, and rain that shows up fast.
The Tri-Cities sit on mostly red clay. It is not the sandier ground you find in other parts of the Southeast, and around here even a small rain can make a very large difference in what is standing under a house.
We work through Kingsport, Bristol, and Johnson City, and we spend a lot of time in the oldest housing stock in the region. Those homes often have extremely high moisture and relative humidity with nothing at all in place: no ground barrier, no drainage, no protection of any kind.
What we see most
- No barrier at allBare soil under the house with high humidity sitting on the framing.
- Standing waterWater inside the space, including finished basements, after a modest rain.
- Older homesThe oldest houses in the area, built long before anyone planned for this.
Common Questions
Johnson City crawl space questions, answered.
Do you do foundation repair?
No. Crawlspace Medic handles crawl space and basement encapsulation, moisture control, and diagnostic inspection. We do not install push piers or helical piers, and we do not do slab leveling. If the inspection reveals foundation movement beyond the crawl space framing, we refer you to a foundation specialist.
How much does crawl space encapsulation cost in the Tri-Cities?
Based on what we are seeing, most homes here are going to need a ground barrier, a wall barrier, a dehumidifier, and vent sealing. On a home around 1,500 square feet, that runs about $8,000 to $9,000, or closer to $7,000 if you go with the 10 mil barrier. The inspection tells us what your house actually needs before we talk numbers.
Why is my crawl space so humid?
Here in eastern Tennessee, especially the Tri-Cities, the ground is mostly red clay, not the sandier soil you see in other parts of the Southeast. In the warmer months precipitation and humidity both run high, and even a small rain can make a huge difference around here. Most of the crawl spaces we inspect have extremely high moisture with zero protection in place, no ground barrier, no anything.
Do I really need encapsulation?
Our honest answer is a question back: do you really need clean air? Through the stack effect, whatever is in your crawl space works its way up into the air you live in every day. Treat your crawl space the way you would treat the inside of your home.
How thick a vapor barrier do I need?
Barriers here start at 10 mil, with 16 and 20 mil options, and the plastic carries a lifetime material warranty. Which thickness fits depends on the home's moisture and how the space gets used, which is exactly what the free inspection settles.
