You stop worrying about what’s happening under your house. The musty smell that’s been creeping into your living room disappears. Your floors feel solid again because the moisture that was softening your joists is gone.
A properly installed French drain doesn’t just move water away from your foundation. It eliminates the conditions that cause mold growth, wood rot, and pest infestations in your crawl space. When humidity stays below 60%, your home stays healthier.
You’re not dealing with puddles after every storm. Your landscaping isn’t eroding. Your foundation isn’t developing new cracks because hydrostatic pressure has been reduced. The system works quietly in the background, doing exactly what it’s supposed to do.
Most homeowners notice the difference within days. The air feels fresher. The crawl space smells like dirt instead of decay. You’re not running a dehumidifier constantly just to keep up with moisture that shouldn’t be there in the first place.
We specialize in crawl space moisture control and indoor air quality for homes throughout Jamestown and the Greensboro area. We understand how North Carolina’s clay-heavy soil and humid subtropical climate create persistent drainage challenges for homeowners in the Piedmont region.
We’ve seen what happens when water sits against foundations in this area. The clay soil retains moisture and directs it exactly where you don’t want it. We’ve installed French drains in enough local crawl spaces to know what works and what doesn’t in Jamestown’s specific conditions.
Our focus is on solving the root problem, not just treating symptoms. When you call us, you’re talking to people who understand the connection between proper drainage and the air quality inside your home. We don’t do residential dryer vents. We focus on what we know: keeping crawl spaces dry and homes healthy.
We start with an inspection of your crawl space and the area around your foundation. We’re looking at where water is coming from, where it’s pooling, and what’s causing the moisture problem. We take pictures and show you exactly what we’re seeing.
The installation involves digging a trench along the problem areas, typically around your foundation or in your crawl space. We slope the trench so gravity does the work. Then we lay perforated pipe wrapped in filter fabric to keep soil and debris out while letting water in.
We surround the pipe with gravel that allows water to flow freely into the drainage system. The pipe directs water away from your foundation to a safe discharge point, whether that’s a dry well, drainage ditch, or another appropriate location on your property.
For crawl space installations, we often tie the French drain into a sump pump system if needed. This ensures water gets removed even when gravity alone isn’t enough. We seal everything properly and make sure the system is working before we’re done.
The whole process typically takes one to two days depending on the size of your home and the extent of the drainage problem. You’ll see the difference after the first heavy rain.

You get a drainage system designed specifically for your property’s grading, soil type, and water flow patterns. Not every home in Jamestown has the same drainage needs. The clay soil in this area behaves differently than sandy soil. We account for that.
The installation includes proper sloping, quality perforated pipe, drainage fabric, and enough gravel to ensure long-term performance. We don’t cut corners on materials because that’s where most French drain failures happen. Cheap pipe clogs. Insufficient gravel causes the system to fail within a few years.
You also get an explanation of how the system works and what to expect. We show you where the water is being directed and why we chose that discharge location. If you need ongoing moisture control in your crawl space, we’ll discuss options like vapor barriers or dehumidification that work alongside your new drainage system.
Jamestown’s climate means you’re dealing with humidity levels that regularly exceed 70% in summer. A French drain addresses the water intrusion problem, but you might need additional moisture control depending on your crawl space conditions. We’ll be straight with you about what’s necessary and what’s optional.
This isn’t a one-size-fits-all service. It’s a solution built around your home’s specific challenges in this region.
Cost depends on how much drainage you need and where it’s going. A basic exterior French drain around one side of a foundation typically runs between $2,000 and $5,000. Full perimeter systems cost more. Interior crawl space French drains with sump pump installation can range from $3,000 to $8,000 depending on crawl space size and accessibility.
The variables that affect price include how much trench we’re digging, whether we’re working inside a crawl space or outside around your foundation, soil conditions, and what kind of discharge system is needed. Clay soil takes longer to excavate than loose soil.
We give you a clear estimate after inspecting your property. No surprises. The price includes materials, labor, and a system that’s designed to last. Cheaper installations often fail because contractors use inadequate materials or don’t slope the trench properly. You end up paying twice.
A properly installed French drain can last 20 to 30 years or longer. The key word is “properly.” Systems fail when contractors skip steps, use poor materials, or don’t account for soil conditions.
The perforated pipe itself is durable. What causes problems is clogging from soil infiltration when the filter fabric isn’t installed correctly, or settling when the gravel base isn’t adequate. In Jamestown’s clay soil, you need enough gravel and proper fabric wrapping or the system clogs within five years.
We install systems that require minimal maintenance. You’re not digging this up and redoing it in a few years. The upfront investment should give you decades of performance. That only happens when the installation is done right the first time.
If water intrusion is your problem, yes. A French drain stops groundwater from entering your crawl space and directs it away from your foundation. That eliminates standing water, reduces humidity, and removes the moisture source that causes mold and wood rot.
But a French drain addresses water coming in from outside. If you also have condensation issues from humid air or plumbing leaks, you’ll need additional solutions. Most crawl space moisture problems in Jamestown involve multiple factors because of our climate.
We assess the whole situation during inspection. Sometimes a French drain is the complete solution. Other times it’s part of a larger moisture control strategy that might include vapor barriers or dehumidification. We’ll tell you what you actually need, not what we want to sell you.
Exterior French drains are installed outside your foundation, intercepting water before it reaches your crawl space or basement. They’re ideal for preventing water intrusion and protecting your foundation from hydrostatic pressure. They handle surface water and groundwater.
Interior French drains are installed inside your crawl space or basement, collecting water that’s already entered and directing it to a sump pump for removal. They’re often used when exterior excavation isn’t possible or when you’re dealing with an existing moisture problem that needs immediate control.
For Jamestown homes with crawl spaces, we often recommend interior systems because they’re more effective at keeping the crawl space dry and they’re easier to tie into sump pump systems. The choice depends on your home’s construction, grading, and where the water is coming from. We’ll recommend what makes sense for your situation.
You need drainage if you’re seeing water pooling around your foundation after rain, if your crawl space is damp or has standing water, or if you’re noticing musty odors coming from below your home. Cracks in your foundation, doors that stick, or floors that feel uneven can also indicate water pressure against your foundation.
In Jamestown, the clay soil and humidity create conditions where drainage problems develop gradually. You might not see standing water, but you’ll smell the mustiness or notice your crawl space feels wet. That’s enough reason to get an inspection.
Most homes with crawl spaces in this area will eventually need drainage solutions. It’s not a matter of if, but when. The earlier you address it, the less damage occurs to your foundation and floor joists. Water doesn’t fix itself. It gets worse.
You can, but most DIY French drains fail within a few years. The concept is simple, but the execution requires understanding drainage principles, proper sloping, soil conditions, and material selection. Small mistakes cause big problems.
Common DIY failures include incorrect slope (water doesn’t flow), inadequate gravel (system clogs), wrong pipe type (collapses or clogs quickly), and poor discharge planning (water comes right back to your foundation). In clay soil like we have in Jamestown, you also need to know how to prevent the trench from collapsing during installation.
Professional installation costs more upfront, but you get a system that works for decades instead of a few years. You also avoid the physical labor of digging trenches in clay soil and the risk of damaging utilities or creating drainage problems worse than what you started with. Most homeowners who try it themselves end up calling us to fix it anyway.
