In Texas, the company that assesses a mold project cannot be the one that remediates it; Texas Occupations Code Chapter 1958 draws that line. Mold Test DFW works only on the assessment side. Before we come to a Lewisville address, a few notes on the room, the smell or stain, and any recent water will help us plan the right samples.

Get the Full Picture Before Repairs
The stain you can see is usually the edge of a larger wet area. Mold testing in Lewisville finds how far the moisture reached, identifies what is growing, and points back to the source, so the repair can be scoped properly. The EPA sets no federal limits for mold in indoor air, so each indoor result is compared with an outdoor sample from the same visit.
Shower Niches and Built-In Benches
Recessed shelves and tiled seats are popular in updated Lewisville bathrooms. Every flat surface inside a shower needs to shed water, or it slowly sends water into the wall.
Niches
A flat or back-sloped shelf holds a puddle after every shower, and the grout in the bottom corners is the first to crack.
Built-in benches
The seat needs a slight slope toward the drain. Water that sits on a level bench works into the grout and the framing below.
Corner shelves
Tile shelves set into the corners rely on the waterproofing behind them. A loose or cracked shelf can let water into the wall.
Mold Testing in Lewisville, Step by Step
- Moisture readings on the walls, floors, ceilings and cabinets near the concern, and in the rooms on either side.
- Air samples when a smell or symptoms are the main clue, paired with an outdoor sample.
- Tape or swab samples where growth is visible, so the lab can identify it.
The meter readings decide which samples are worth taking.
An Independent Lewisville Mold Testing Company
- We do not quote or perform remediation, so the report has no sales angle.
- An independent laboratory analyzes every sample.
- Your written report connects each sample location to its result and a next step.
Our mold testing services in Lewisville are available to homeowners, renters and buyers, and you choose who receives the report.
When Lewisville Homeowners Call
Mold testing in Lewisville is worth scheduling when:
- A musty smell keeps coming back to one room or closet.
- Paint is blistering or a stain is spreading near a bathroom, window or outside wall.
- Flooring has lifted, cupped or softened in one spot.
- Water got in from a leak, an overflow or a storm, even briefly.
- Someone in the home feels better when away from it. We are not medical providers, so please see your doctor about symptoms; the CDC explains how mold can affect health.
How the Appointment Works
- Questions: what you noticed, where, and when.
- Readings: moisture meters in the area and the rooms next to it.
- Sampling: air, surface or both, chosen from the readings.
- Laboratory: sealed samples analyzed by an independent lab.
- Report: written findings and a call to go over them.

Reading on Mold and Moisture
We point people to the EPA brief guide to mold, moisture and your home, the CDC overview of mold and health, and the TDLR mold program, which licenses mold assessors.
After the Report: Who Does What
If a Lewisville mold testing report shows that remediation is needed, a separately licensed mold remediation contractor does that work, not us. For larger projects, Texas rules call for a written protocol from a licensed assessor that sets out the scope and how completion will be judged. Once the work is done, a post-remediation assessment checks the result against that protocol. Ask any contractor you consider for their TDLR license number.
Painted Brick and Trapped Moisture
Painting or sealing brick is a popular update. How well the coating lets the wall dry decides how it holds up.
Brick takes on water
Brick and mortar absorb rain and dry out again between storms. That cycle is normal, as long as the moisture has a way out.
Some coatings hold it in
Certain paints and sealers slow how fast brick can dry. Trapped moisture can push the coating off and crumble the face of the brick.
What to watch
Peeling paint low on the wall, flaking brick faces, white powder at the mortar joints, or a musty smell on the inside of that wall.
A masonry contractor or the coating maker can recommend a breathable product for brick. If the inside of a painted wall shows stains or smells musty, a moisture reading will tell you whether it is wet.
Reviews From DFW Homeowners
He was able to get in, do a complete thorough walkthrough, send samples off to the lab, and write a report up for us (that included a massive amount of broken down details), all before our option period ended.
Highly recommend using this company for anything, they definitely don’t disappoint!
What really stands out is how easy he is to work with. Ryan makes the entire process smooth and stress-free. His attention to detail with paperwork is also top-notch—everything is always accurate, complete, and submitted promptly.
If you're looking for someone reliable, knowledgeable, and genuinely dedicated to their work, Ryan is the one to call. Highly recommended. United Water Restoration group Arlington, Texas Operations Manager, James Johnson
From the very beginning, Ryan was outstanding—he explained the testing process clearly, answered all of our questions, and made the entire experience stress-free. The appointment was scheduled quickly, and he arrived right on time with all of his professional equipment.
What really impressed us was how thorough and detail-oriented Ryan was. He didn’t just take air and surface samples—he explained each step of the process so we understood how the testing works and what the results would show. He was professional, respectful of our home, and very transparent about what he was doing.
Compared to other companies we’ve used in the past, Mold Test DFW was by far more honest and customer-focused. The final report was easy to understand, very comprehensive, and gave us peace of mind to move forward with the right remediation decisions.
If you need accurate, reliable, and trustworthy mold testing, I highly recommend Mold Test DFW. Ryan went above and beyond, and we’ll absolutely call them again in the future if we ever need testing.
From Holford’s Prairie to a Lakeside City
Baptist settlers from Missouri, among them John and James Holford, arrived in the early 1840s and called the area Holford’s Prairie. Basdeal Lewis bought it in 1853 and renamed it after himself. Residents voted to incorporate on January 15, 1925, by a margin of 17 votes. The Garza-Little Elm Dam was finished in 1954, creating what is now Lewisville Lake. The population grew from 1,516 in 1950 to 46,521 in 1990 and 111,822 at the 2020 census.
Most of that growth came after 1970, so Lewisville holds a wide mix of houses from the past fifty years, many likely on a replacement water heater or roof by now. Our mold testing company in Lewisville pays close attention to those replacements, because the connections made during a swap are common places for slow leaks.
Faster Answers, Smaller Repairs
The EPA recommends drying wet building materials within 24 to 48 hours to prevent mold growth. Wait longer and the repair usually grows. Mold testing in Lewisville early on can mean:
- Replacing a small piece of drywall rather than a full wall.
- Finding a slow leak before it ruins a vanity or subfloor.
- Having dated results for an insurer, a landlord or a buyer.
The Window Over the Kitchen Sink
A window behind the sink gets splashed many times a day. It is one of the easiest places in a kitchen for water to settle in unnoticed.
How Texas Licenses Mold Assessors
The Texas Department of Licensing and Regulation licenses mold assessment consultants. A license generally requires approved training and an exam, and renewal requires insurance and continuing education. Before anyone samples your Lewisville home, ask for the license number and look it up on the TDLR website. We will share ours anytime.
Mold Test DFW sends certified mold inspectors to every appointment, backed by mold assessment consultants who are trained and certified.

Lewisville Mold Testing Questions
The kitchen sink smells musty. Is it the garbage disposal?
Often it is food residue in the disposal or the drain. Clean the disposal and run water through it. If the smell stays, open the sink cabinet and check the cabinet floor and the back wall, because a slow drip from a supply line or the drain can cause the same smell.
The seller already had a mold test done. Should I get my own?
It is worth considering. Find out when that test was done, who did it, and what was sampled. Conditions can change, and a report ordered by the seller was written for the seller. Ask your agent how a second test fits your option period. We are not attorneys.
Is the mildew on my patio furniture cushions a problem for the house?
Not usually. Outdoor cushions that stay wet after rain grow mildew on their own. Let them dry in the sun, store them somewhere dry, and keep damp cushions out of closets and the garage, where they can spread the musty smell.
Will you need to cut into my walls?
Usually not. Mold testing relies on moisture readings and air or surface samples. If a conclusion would need a wall opened, the report says so, and you and your contractor decide whether to open it.
Does living near Lewisville Lake make my house more humid?
A lake can raise humidity right at the shoreline, but for most homes the bigger factors are the weather, the air conditioning, ventilation and any leaks. A house that feels damp year round is worth checking whether or not it is near the water.
