Signs to look for
When to call us for moisture detection
If you notice any of these problems, call us before water has more time to spread into nearby materials.
Your water bill jumped without a change in habits
A supply leak inside a wall or under a slab can run for weeks without a puddle. Mapping the wet area tells you which plumbing wall to open first.
A musty smell that comes and goes
Odor that strengthens on humid days usually means damp material somewhere with poor airflow. The smell travels much farther than the wet spot.
One patch of floor is always cooler than the rest
Evaporative cooling makes a damp area measurably colder at the surface. It is one of the most reliable hints of hidden moisture underfoot.
Paint or wallpaper bubbling away from the known leak
Water wicks sideways through gypsum and paper faces. Bubbling several feet from the source means the migration path is longer than the visible damage.
Flooring lifting in a doorway two rooms away
Doorways and thresholds are where water crosses between rooms and where the flooring reacts first. Lifting there means the water already traveled.
What happens
How we handle moisture detection
Our team adjusts the work to what got wet, how far the water traveled, and which materials can be saved.
A pinless sweep of walls, floors and ceilings
A pinless moisture meter reads through a surface without marking it, so we can scan a whole room quickly.
Pin meter confirmation at suspect points
A pin moisture meter uses two small probes to measure at a known depth. It confirms what the sweep suggested, giving a hard number in wood and a comparable reading in gypsum.
Thermal imaging with its limits explained
A thermal imaging camera shows surface temperature patterns that often reveal damp areas fast.
Ambient readings with a hygrometer
We record temperature and humidity in the space and in unaffected rooms. Those hygrometer numbers explain what the material readings mean.
Cavity inspection where access allows
A borescope or inspection camera goes through a small hole to look inside a wall or ceiling cavity.
Dry reference readings from unaffected material
Every wet reading is compared to a dry reference reading on the same material elsewhere in the building.

What to expect
What to expect from our team
Here is how we usually handle moisture detection near San Antonio, TX 78298.
-
1
Tell us the story and leave things as they are
We ask when it happened, what got wet, and what has been done since. Please do not repaint, re carpet or close any wall until it has been read.
Your call -
2
History walkthrough on site
The technician walks the property with you and looks at what is above, below and behind the affected area.
On arrival -
3
Pinless sweep to find the edges
We scan out from the known wet area in every direction until readings return to normal. That is how the boundary gets established rather than assumed.
First 15 minutes -
4
Pin readings and cavity checks
Suspect points get confirmed with pin probes, and cavities get looked at with a work plan where access allows.
Next 30 minutes -
5
Thermal scan and verification
The camera is used to find temperature differences worth investigating. Every one of them is then checked with a meter to rule out a false positive.
During the survey -
6
Reference readings from dry areas
We take readings on the same materials in unaffected rooms to set the baseline. Comparison is what turns a number into a conclusion.
During the survey -
7
The map is drawn and walked through with you
Before we leave, you see the moisture map and the readings behind it. You will know how far the water went and how confident we are about it.

Understanding the cost
What can affect the price
We explain the recommended work and price before you approve the job. These examples show what may change the estimate.
| Common situation | What the estimate may include | Typical range |
|---|---|---|
| Standard water damage inspection with meter readings and moisture map | National estimate for a home visit with photos and a written summary. | $150 to $400 |
| Inspection with thermal imaging and a full written report | National estimate. Common when an insurer, a landlord or a buyer needs documentation. | $250 to $600 |
| Large home or commercial mapping, per hour | National estimate for hourly technician time on properties too large for a flat fee. | $75 to $200 |
| Second opinion or post repair verification inspection | National estimate for checking another company's completed work or reading a wall before it is closed. | $200 to $500 |
| Inspection fee applied toward the work if you hire the company | National estimate. Many companies apply the inspection fee toward the mitigation invoice if you hire them, so ask when you call. | $0 to $150 |
Size of the property
A one room check is quick. Mapping a whole house means scanning every wall, floor and ceiling that could be on the migration path.How many levels are involved
Water from an upper floor puts three assemblies in play: the floor above, the cavity between, and the ceiling below.Whether thermal imaging is used
Infrared scanning adds time and equipment but shortens the search on large or complicated properties. On a single wet room it is often unnecessary.Cavity access
Tile, plaster, brick and built in cabinetry all make it harder to read or work plan a cavity.The report format you need
A verbal walkthrough with photos is the quickest. A full written report with a drawn moisture map for an insurer, a landlord or a lawyer takes longer to produce.How long ago the water event happened
Fresh losses read clearly. An old event that partially dried takes more probing and interpretation to bound accurately.
Why timing matters
What can happen when the area stays wet
Water can keep moving into nearby materials even when the surface looks dry.
Repairs get built over wet material
New paint, trim and flooring installed over damp gypsum or framing trap the moisture behind them. The work comes back out at your expense.
An unmapped pocket keeps a job unfinished
Drying only what is visible leaves damp material behind a cabinet or under a threshold. That pocket can support mold within 24 to 48 hours.
Guessing large costs you in demolition
Crews without readings tend to cut a wider line to be safe. Mapping frequently saves more drywall and flooring than the inspection costs.
Your claim gets limited to what was documented
Adjusters pay for damage that is shown to exist. Undocumented rooms are hard to add back once the equipment has already come out.

Start with the short explanation. Open a card if you want a little more detail.
What is happening inside the property
Gravity carries it to the lowest point it can reach, and then water wicking takes over.
Read the explanation
Water goes down first and then sideways, which is why the damage rarely matches the leak. Gravity carries it to the lowest point it can reach, and then water wicking takes over.
How the next step is decided
A pinless meter compares the electrical properties of the material under a sensor plate, which makes it fast for finding where a wet area ends.

Meters and cameras each answer a different question. A pinless meter compares the electrical properties of the material under a sensor plate, which makes it fast for finding where a wet area ends.
What may change the work
The camera sees only surface temperature, so what it actually reveals is a pattern, not moisture.

Common questions
Questions about moisture detection
How much does a moisture inspection cost?
Nationally, most home inspections with meter readings and a moisture map run about $150 to $400. Adding thermal imaging and a full written report typically puts it at $250 to $600.
Can a thermal imaging camera see water through walls?
No, and anyone who says otherwise is overselling it. The camera reads surface temperature, and wet areas often look cooler because evaporation cools them.
What is the difference between a pin and a pinless meter?
A pinless moisture meter reads through the surface using a capacitance reading, so it scans large areas fast without marks.
Will you make holes in my walls?
Only with your permission, and only where readings justify it. A borescope hole is about the size of a pen and usually goes in a spot that will be painted or hidden anyway.
Can I just buy a moisture meter and check it myself?
You can, and an inexpensive meter will tell you wet from dry in a rough way. What it will not do is give you a calibrated comparison against dry reference material or interpret a false positive from foil backed insulation, metal or wiring.
Will insurance pay for the inspection?
Usually yes when it is part of a covered loss and the mapping supports the mitigation work plan.
How do you know how far the water spread?
We scan outward from the known wet area until readings match unaffected material, in every direction including up and down.
