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, Wilmington homeowners feel it upstairs: musty air, sticky rooms, and higher power bills.
Why the coast calls us first
Why we're the crawl space company Wilmington homeowners trust.
We're local and know our market: Wilmington sits beside a huge body of water, and the water table under our homes normally rides just two and a half to three feet below the surface. Moisture pushes up from the ground while humidity pours in through the foundation vents, which is why the traditional vented crawl space, a fine idea in drier places, usually fails here. Ben Chesnut, who leads our business development and has been under close to 3,000 area homes, has watched summer condensation literally rain inside a crawl space. They become their own little ecosystem.
Out-of-region companies miss this. We have watched systems installed here that work beautifully where those companies come from and do nothing about a coastal water table. And almost every local house carries some degree of fungal staining, even new construction that got rained on during framing, so the question is never whether a crawl space has seen moisture.
“I've literally been in crawl spaces during the summer where it was raining inside from condensation. They become their own little ecosystem.”
Five things, done well.

What Wilmington Homeowners Say
Customer Reviews, in their words.
“Travis was very honest and professional explaining what was going on in my crawl space. He showed pictures of the issues and suggested the best solutions for each area. He could not have been nicer or more knowledgeable. Your company representatives are better each time I meet one of them. Thanks for your great service.”
“The team at Crawlspace Medic of Wilmington is fantastic. I had them replace and install a faulty dehumidifier. The unit was under warranty and they took care of everything for me. They came back today and inspected the unit and the crawlspace. They said all was great and did not charge me for the visit.”
“Crawlspace Medic of Wilmington® did an excellent job on my property. All of my under-floor insulation in under the house had fallen down and the original vapor barrier (cheap/thin 1990's plastic) was pretty much non-existent. Crews were professional, on time and hustled. Can already tell the difference in the house holding heat better and longer that before.”

How It Works
Simple, and on your terms.
Free inspection
Every crawl space deserves to be looked at, and ours costs you nothing. We inspect the whole space, even the ones under two feet tall that other companies will not crawl.
An itemized proposal
You get every recommendation listed out with its own price, so you can see what each repair actually accomplishes. If you do not see the value in a line, we do not want to sell it to you.
We fix the cause
With the water right next to us and high water tables, a traditional vented crawl space usually does not hold up here, so 16-mil barrier is our standard on this sandy soil, with 10-mil offered as the lower-cost option. Structural work is done with real footings, CMU piers, sister joists and replaced girders, not screw jacks or steel beams.
Sealed beats vented on the coast
Shut off the moisture and the house exhales.
We have a huge body of water right next to us, so it is always humid and wet here, and we have high water tables on top of that. Traditional vented crawl spaces usually are not successful in those conditions. You are fighting moisture coming up from the ground and humidity coming in through the foundation vents at the same time. In normal conditions the water table can sit only about two and a half to three feet below the surface.
What works in other parts of North Carolina does not necessarily work here. We have watched companies come in from other regions and install systems that perform great where they are from, because they do not understand our conditions. Because we have a lot of sandy soil, a 16-mil vapor barrier is our standard recommendation, with a 10-mil option for customers who want something more cost-effective. A lot of crawl spaces here are very low, sometimes under two feet tall, and once you add ductwork they get hard to work in. Another moisture remediation company in town refers those jobs to us because they will not work in spaces that tight.

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
Report came back with staining under the house?
Nearly every home around here shows some degree of staining or fungal growth, and plenty of it dates back to rain during construction, so it is worth having someone read it correctly before you panic. Come let us look, free, and we will tell you what actually needs repair and what does not.
The Crawlspace Medic difference
Itemized, overbuilt, and honestly priced.
Every proposal we write is itemized: each recommendation, what it accomplishes, and what it costs, line by line. If you do not see the value in an item, we would rather drop it than sell it. Local engineers tell us they appreciate that we tend to overbuild rather than cut corners: structural work here means proper footings, CMU piers, sister joists, and replaced girders, never screw jacks or steel beams that a buyer's inspector might call temporary.
We also know when to stop. Not every crawl space wall needs encapsulating, and when yours does not, we say so. And when a space runs under two feet tall with ductwork eating half of that, our crews still fit; another moisture remediation company in town sends us those jobs because they will not crawl them.
On price, honesty cuts both ways. Last year our average real-estate transaction repair came in around $5,400, while this month several jobs passed $20,000 because that is what those homes genuinely needed. For scale: loose-plastic crews charge $1,000 to $2,000, the chains' national average sits at $15,000 to $30,000, and most of our work lands in the $5,000 to $10,000 middle. We price the actual problem, not a package.
Look at what our completed Wilmington jobs actually bill for and you see the same short list over and over: vapor barrier, fungal treatment, sump pumps, insulation, and 10-mil liner.
“Nobody is showing off their crawl space to friends. They just want it fixed correctly.”

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
$5,000–$10,000
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 $5,000–$10,000 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
Whoever goes under your house, get pictures.
Ben's standing advice: any time an HVAC technician or plumber goes under your home, ask them to take photos. When the HVAC tech says everything looks good down there, he means the ductwork, not your girders, and the plumber is not looking for rotten joists. Our free inspection reads the structure and the moisture together, with wood-moisture readings taken directly: 12 to 16% is sound, over 20% is a working problem. If we find problems outside our specialty, we hand you contractors we trust.

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.
The repair a neighborhood noticed
Local Story
Just north of town, our Wilmington office completed one of the largest structural repairs it has ever taken on. Since then, Ben has taught two classes for the real-estate community where attendees raised their hands to thank us for fixing that house, because they knew what it would have meant for the surrounding neighborhood if it had kept failing. That is the quiet math of structural work on the coast: one properly repaired home protects the street around it.

Our Guarantee
Referrals beat unnecessary work
“We give customers itemized proposals so you can see every recommendation and what it costs, then decide where you see value, and if you don't see value in something we don't want to sell it to you. We do not automatically encapsulate every crawl space wall, because if it is not needed we are not going to recommend it. We handle moisture control and structural repair under the house using original construction techniques, footings, CMU piers, sister joists, and replacement girders, and we are not a full-service foundation repair company doing push piers, helical piers, or slab leveling. If we find a problem outside our specialty, I have trusted contractors I will point you to instead.”
Conditions in Wilmington
Sandy ground, a high water table, and air that never dries out.
Wilmington sits on sandy soil beside a lot of water, and the water table here is high. In normal conditions it can sit only two and a half to three feet below the surface. That is a large part of why a heavier 16 mil barrier is our standard recommendation on the coast rather than the thinnest option on the shelf.
The air does the rest. This close to the water it stays humid, and a traditional vented crawl space pulls that air straight in and holds it. We have been in crawl spaces in the summer where it was raining inside from the condensation. They become their own little ecosystem down there.
What we see most
- Vented crawl spacesThe traditional vented design does not hold up in this climate.
- Low clearanceMany spaces here are under two feet tall, and ductwork makes them tighter.
- Stained framingEven new homes get rained on during construction and carry the marks for life.
- GroundwaterA water table that sits close enough to the surface to reach the space.
Common Questions
Wilmington crawl space questions, answered.
Do you do foundation repair?
No. Crawlspace Medic handles crawl space encapsulation, repair, and diagnostic inspection. We do not install push piers or helical piers, and we do not do slab leveling. If your inspection reveals foundation movement beyond the crawl space framing, we refer you to a foundation specialist.
How much does crawl space work cost in Wilmington?
Last year our average real-estate transaction repair was around $5,400, but the honest answer is a range: some homes this year needed more than $20,000 because that is what was wrong with them. Market-wide, loose-plastic jobs run $1,000 to $2,000, chain quotes average $15,000 to $30,000, and our typical job falls between $5,000 and $10,000. The itemized proposal from a free inspection is the real number.
Is fungal staining in the crawl space a dealbreaker when buying here?
Our honest answer is that if it is, you are probably not going to live around here. Almost every house in this area has some degree of staining or fungal growth. Even brand-new homes often get rained on during construction, which can leave staining on the framing for the life of the house. What matters is whether the moisture is under control, and that is what the inspection tells you.
My crawl space is too tight for other companies. Can you work in it?
Almost certainly. A lot of crawl spaces here are less than two feet tall, and once you add ductwork they get difficult to work in. Our crews have the experience to handle those. Another moisture remediation company in town actually refers those jobs to us because they do not work in crawl spaces that tight.
Would I be better off with a slab home than a crawl space?
Ben actually lives on a slab, so let him tell you about slabs. There is essentially no maintenance until suddenly you are facing a $20,000 or $30,000 repair, and you often cannot see the problem until a major renovation opens things up. With a crawl space you have complete access underneath the home, so you can catch problems before they become extremely expensive.
