Your Floor Is Dry.
Your Walls Aren't.

Professional structural drying across Edmond and OKC. I answer my phone, show up with the right equipment, and dry your house until the readings say we're done.
The Water You Can't See Is the Water That Matters
The extraction crew leaves. You look around. The carpet isn't floating anymore. The floor doesn't squish when you walk on it. You think: okay, we're good.
You're not good. You're at the part where the damage goes invisible.
Here's what's actually happening after the standing water is gone: moisture has soaked into your drywall, traveled up behind your baseboards, saturated your insulation, and settled into your subfloor. It's inside your walls where you can't see it, can't feel it, and wouldn't know it's there without a meter.
Press your hand against the wall near the baseboard. Feel that coolness? That's moisture behind the paint. Bend down near the floor trim. That faint smell? That's water feeding bacteria in material that was never meant to stay wet.
Structural drying is the science of getting that hidden water out — not just the water on the floor. Not just what you can see or feel. The water inside the building materials themselves.
And it's not just pointing fans at wet stuff and hoping. It's physics. You need three things working together:
- Airflow across the wet surface — accelerating evaporation
- Dehumidification — pulling moisture out of the air so it doesn't just settle somewhere else
- Temperature control — keeping the environment in the optimal range for evaporation
Miss any one of those three, and you're just running electricity. The water stays, the materials stay wet, and mold gets its invitation.
Grain depression is the most exciting thing in my day that nobody at dinner wants to hear about. But it's the number that tells me whether the system is actually working. It's the gap between how much moisture the air could hold and how much it's currently holding. Bigger gap means the air is actively pulling water out of your building materials. If the gap isn't big enough, I'm not drying — I'm just making noise.
Mold Doesn't Wait. Neither Should Your Drying Plan.
I'm not going to scare you into calling me. But I'm going to tell you what happens biologically when building materials stay wet:
Within 24-48 hours, mold spores — which are already everywhere in the air — find wet material and start colonizing. You won't see it yet. By the time you see it, you're looking at a remediation project, not a drying project.
Within 72 hours, wood framing begins to absorb enough moisture to weaken. Drywall loses structural integrity. Insulation compresses and stops insulating.
Within a week, secondary damage is setting in. Floor joists swell. Crown mold starts behind walls. The conversation shifts from "how much to dry this" to "how much to replace this."
None of this is a scare tactic. It's microbiology and material science. The timeline doesn't negotiate.
The math is simple: structural drying addresses the problem when it's still manageable. Waiting turns a drying job into a mold remediation project — and those cost significantly more and take significantly longer. That's why your insurance policy specifically covers mitigation: the work that prevents worse damage.
Here's What Happens When I Show Up
Step 1: Assessment — Moisture Mapping
First thing I do is take readings. Not a quick glance — real readings. Pin-type moisture meter on the drywall at multiple heights. Thermal imaging camera to see where the moisture traveled that you can't see. Psychrometer to measure temperature and humidity in the air.
I'm measuring at least 20 points across the affected area. I'm measuring walls, floors, ceilings, and the area around the damage to establish what "dry" looks like in the rest of your house. That baseline is how we know when we're actually done.
I'm building a picture of what your house looks like from the water's perspective. Where did it start? How far did it travel? How deep did it go?
Step 2: Equipment Setup — Precision, Not Guesswork
Every air mover has a calculated angle — not just "pointing at the wall." A specific angle based on distance, surface type, and where the moisture wants to go. Dehumidifiers get positioned for optimal airflow and grain depression. If the space is sealed off from the rest of the house, I'm controlling temperature too.
Every piece of equipment has a job and I can tell you what it's doing.
Step 3: Monitoring — I Come Back
This is where a lot of companies disappear. Equipment gets dropped off, and three days later somebody comes back to pick it up.
I come back. I take readings — the same points, documented the same way. If the numbers are dropping, we're on track. If they're not dropping or they're dropping too slow, I adjust. More air movement. Different dehumidifier placement. Find a hidden moisture pocket that wasn't obvious on day one.
I come back every day until the numbers say we're done.
Step 4: Verification — Readings, Not Guesswork
We're done when the pin meter reads under 16% moisture content and the relative humidity is within 5% of ambient conditions in the unaffected parts of the house.
Not when it "looks dry." Not when the calendar says three days. When the instruments say the structure is dry.
I document every reading, photograph every measurement point, and provide a complete drying log. Your insurance adjuster gets the same documentation I'm looking at. There's nothing hidden.
My Equipment vs. What You Can Rent at the Hardware Store
I'm not going to tell you that you can't dry your house yourself. I'm going to show you the math.
Your household dehumidifier and my LGR dehumidifier are both called "dehumidifiers." In the same way that a canoe and an aircraft carrier are both called "boats."
Your home dehumidifier:
- Removes about 30 pints of moisture per day
- Works effectively down to about 45% relative humidity
- Designed for a single room's ambient moisture
- Costs about $250
My LGR (Low Grain Refrigerant) dehumidifier:
- Removes 150+ pints of moisture per day
- Works effectively down to 25% relative humidity
- Pre-cools incoming air to maximize condensation
- Designed to pull water out of structural materials, not just air
And I bring more than one.
The air movers are the same story. A box fan pushes air at about 500 CFM. My commercial air movers push 3,000+ CFM at a controlled velocity designed to create laminar airflow across wet surfaces. That's not a bigger version of the same thing — it's a different category of tool.
I check moisture levels the way some people check their fantasy football scores. Every morning. Before coffee.
Oklahoma Doesn't Dry Like Other States
If you live in Oklahoma, your house faces drying challenges that a company from out of state wouldn't understand.
Slab foundations are the most common in the OKC metro. When water gets between the slab and the flooring, there's nowhere for it to go naturally. We use floor mat drying systems and perimeter air movement because gravity isn't helping us — the moisture has to be pulled UP through the flooring material. That takes longer and requires specific equipment.
Pier-and-beam houses have a crawlspace underneath, which gives us airflow below the subfloor. That's an advantage — but it also means the subfloor joists and insulation can hold water for weeks if nobody checks. I've pulled wet insulation out of crawlspaces a month after the original water event because nobody looked.
Oklahoma clay soil holds moisture like a sponge. After heavy rain, moisture pressure against your slab doesn't stop when the rain stops. That's why slab leaks in Oklahoma tend to be persistent — the ground stays saturated for days, continuing to push moisture into the structure.
Humidity patterns matter too. Oklahoma summers push humidity above 80% outside, which means the air I'm using for evaporation needs more help from the dehumidifiers. In winter, freeze-thaw cycles can cause pipe bursts followed by drying conditions that are actually pretty favorable — cold, dry air is easier to work with than hot, humid air.
I live here. I dry houses here. I know what Oklahoma does to buildings. Learn more about my approach.
Your Adjuster Uses Software. I Use Moisture Readings.
Let me explain how insurance drying claims actually work, because this is where homeowners get frustrated and it's usually a communication problem.
Your adjuster estimates drying time using Xactimate software — the same software I use for scoping. It calculates a predicted drying time based on square footage, material type, and water category. That's a reasonable starting point.
But it's a prediction. Not a measurement.
I take actual moisture readings from your actual walls. If the readings say the structure is dry on day 3, we pull the equipment. If the readings say it's still wet on day 3, we keep drying.
When the predicted timeline and the actual timeline don't match, I submit a supplement — a documented request for additional drying time with the readings to prove it's necessary. I've never had an adjuster argue with documented moisture data. They might question the initial scope. They don't argue with physics.
What I document for your claim:
- Initial moisture readings (baseline and affected areas)
- Daily monitoring logs with readings at each measurement point
- Equipment placement and settings
- Final verification readings (proof of dryness)
- Photographs at every stage
That documentation package is what I hand your adjuster. Not a guess. Not an estimate. Measurements.
Questions I Actually Get Asked
admin@4d : ~/faq $ query --id=01 "What's the difference between an LGR dehumidifier and the one I can buy at Home Depot?" ▶ ENTER
About 120 pints a day and the ability to work at lower humidity levels. Your household dehumidifier is designed to keep your living room comfortable. My LGR dehumidifiers are designed to force moisture out of structural materials — drywall, wood framing, concrete — at rates that outrun mold growth. They pre-cool the air before condensing moisture out of it, which is how they work at humidity levels your home unit would give up on. They're not bigger versions of the same tool. They're different tools.
admin@4d : ~/faq $ query --id=02 "You keep saying 'moisture readings' — what are you actually measuring and what do the numbers mean?" ▶ ENTER
I'm measuring three things. First, the moisture content of your building materials — I push pins into the drywall or wood and measure the electrical resistance between them. Wet material conducts more electricity. That gives me a percentage number. Under 16% is dry for most materials. Second, I'm measuring the relative humidity and temperature of the air with a psychrometer, which tells me how much moisture the air is carrying vs. how much it could carry. Third, I'm looking at those numbers together — the gap between them (the grain depression) tells me how efficiently the system is pulling moisture out of the structure. If the numbers look good, we're drying. If they don't, I adjust.
admin@4d : ~/faq $ query --id=03 "Can structural drying save hardwood floors that are already cupping or buckling?" ▶ ENTER
Cupping is often salvageable. Buckling is a harder conversation. Here's the difference: cupping happens when the bottom of the wood absorbs more moisture than the top — the edges curl up. That can often be reversed with controlled drying that targets the underside of the flooring. We dry slowly and evenly to prevent overcorrection. Buckling happens when the wood expands beyond what the installation can contain and the boards literally lift off the subfloor. If the fibers aren't broken and the board still flat down under its own weight, we have a shot. If the boards are tenting or cracked along the grain, drying won't fix structural damage to the wood itself. I'll tell you what we're working with before we start.
admin@4d : ~/faq $ query --id=04 "What happens if you don't dry the structure and just replace the wet materials instead?" ▶ ENTER
You can. But you probably shouldn't. Replacement means demolition — ripping out drywall, baseboards, sometimes flooring and framing. Then you're rebuilding. That's reconstruction, which is a different trade from what I do. Structural drying saves materials in place: your existing drywall, your existing framing, your existing insulation. If the materials pass protocol — meaning they reach target moisture levels within the right timeframe — they don't need to come out. My entire business model is saving as much of the structure as possible. I don't do reconstruction, so I have zero financial incentive to demo your house. <a href='/services/water-damage/'>Learn more about our water damage services</a>.
admin@4d : ~/faq $ query --id=05 "How does structural drying work differently for a slab foundation vs. a pier-and-beam house?" ▶ ENTER
They're fundamentally different drying environments. Slab foundations trap water between the concrete and the flooring, so we use floor mat drying systems that create suction beneath the surface material and pull the moisture up and out. There's no airflow underneath a slab — we have to create the escape route. Pier-and-beam houses have a crawlspace, which gives us natural airflow below the subfloor. We can place equipment both above and below the floor assembly. But crawlspaces also mean exposed joists and insulation that can hold moisture for weeks — they need to be inspected and dried too, not just the living space above.
admin@4d : ~/faq $ query --id=06 "My adjuster said the drying should only take 3 days — what if it takes longer?" ▶ ENTER
Then we keep drying and I submit a supplement. Your adjuster's estimate is based on software that uses national averages for drying time. I'm basing my timeline on actual moisture readings from your actual walls. Sometimes the software's right. Sometimes it isn't — especially in Oklahoma where humidity levels and foundation types don't always match national assumptions. When the numbers disagree, I document every reading, submit the data to your adjuster, and request authorization for continued drying. The documentation speaks for itself. Adjusters follow measurements.
admin@4d : ~/faq $ query --id=07 "Is it safe to sleep in my house while the structural drying equipment is running?" ▶ ENTER
Safe? Yes. The equipment is industrial but it's not dangerous — air movers push air, dehumidifiers remove moisture, neither produces harmful byproducts. Quiet? No. Air movers run around 60-65 decibels, roughly equivalent to a loud conversation or a dishwasher. Most people adapt after the first night. Closing the bedroom door and running a white noise machine helps. The more important question is whether the affected area is properly contained, which I handle with plastic sheeting and negative air when needed. If the damage is severe enough to affect air quality — Category 2 or <a href='/services/water-damage/sewage-cleanup/'>Category 3 water</a>, or if we suspect mold — I'll tell you straight whether staying is a good idea.
If you've got water damage and the standing water is out, call me. I'll come take readings, tell you exactly what I'm seeing, and give you a straight answer on what needs to happen next.
If your house doesn't need professional drying, I'll tell you that too.
