Clean water
Water from a sanitary source — a broken supply line, a water heater, a tub left running. ANSI/IICRC S500 notes it does not stay Category 1 forever: time, temperature and contact with building materials can push it into Category 2 or 3.

In the charming neighborhoods of San Antonio like Alamo Heights, where historic homes sit on slabs and some on crawl spaces, residents are all too familiar with the city's unique flash flood risks. Flash floods can rapidly inundate properties, driving rainwater into homes and leaving significant damage. When you call (830) 243-6060, United Water Restoration Group of San Antonio is ready to mobilize quickly to address your flood damage issues. Our team swiftly undertakes water extraction, structural drying, and comprehensive restorations, ensuring your property is back to its pre-flood state swiftly and efficiently.
When flash floods strike in areas such as Stone Oak and The Dominion, water can quickly make its way under flooring, into baseboards, and wall cavities due to the slab foundations on which most local homes are built. Rapid water intrusion often leads to significant secondary damage if not promptly addressed. At United Water Restoration Group of San Antonio, we understand the unique challenges that slab and crawl space construction present, and our crew is equipped to handle these specific concerns, ensuring your property is safeguarded against further moisture damage.
Proper flood cleanup is critical to avoid long-term complications, including mold growth, which many residents are unfortunately too familiar with. Moisture that remains unchecked can lead to mold, especially in our humid climate. We provide cutting-edge thermal imaging inspections and moisture mapping to identify and remove moisture from hidden areas, effectively preventing future mold issues and protecting your home.
Our team uses a variety of advanced equipment tailored to efficiently manage flood cleanup in San Antonio homes. High-performance pumps are utilized for initial water extraction, rapidly removing standing water from your property. Once water extraction is completed, we deploy industrial-grade air movers and dehumidifiers, such as low-grain refrigerant dehumidifiers, to achieve thorough structural drying. This technology ensures that moisture is effectively eliminated, reducing the risk of structural weakening and mold growth.
Contemporary techniques like moisture meter readings provide us a precise assessment of water penetration and relative humidity levels within your property, forming the basis for a detailed scope of work. Additionally, negative air machines and containment barriers help prevent cross-contamination, while antimicrobial treatments sanitize surfaces, promoting a clean and healthy environment post-restoration.
Handling insurance claims following flood damage can be daunting. United Water Restoration Group of San Antonio is committed to making this process as smooth as possible for you. Our expertise in working closely with insurance adjusters means we're adept at documenting the necessary steps for filing comprehensive claims. Category 1, 2, or 3 water damage classifications are all addressed according to IICRC S500 standards to ensure transparency and accuracy.
Moreover, our team maintains daily drying logs to keep all work thoroughly documented, aiding you in your discussions with the insurance company. An industry-standard estimating tool is used to quantify damages accurately, reinforcing your claim and ensuring that all necessary repairs are covered adequately. We're here as an advocate on your behalf, guiding you through each step of the claims process with clarity and care.

Call (830) 243-6060How It Works
The hardest part of property damage is facing it on your own. You do not have to — from the first phone call, it is our job, not yours.
Step 01
Upon arrival, our team conducts a quick yet thorough assessment of the damage. Using submersible pumps and high-capacity vacuums, we remove standing water to prevent it from spreading further.
Step 02
Advanced moisture meters and thermal imaging help us identify water infiltration. This step ensures complete moisture removal, reducing the risk of ongoing damage that leads to mold.
Step 03
Air movers and low-grain dehumidifiers are deployed to dry walls, floors, and furniture. This step is crucial to prevent mold and keep your home’s structure sound and safe.
Step 04
Once dry, we apply antimicrobial treatments to all affected areas, ensuring that surfaces are sanitized and free of potentially harmful microbes and contaminants.
Step 05
A final inspection ensures that all moisture has been eliminated and restoration is complete. We work with you to restore your home to its former glory, providing peace of mind.
The restoration standard sorts water by how contaminated it is, and that classification — not how much of it there is — decides what can be dried and what has to go.
Water from a sanitary source — a broken supply line, a water heater, a tub left running. ANSI/IICRC S500 notes it does not stay Category 1 forever: time, temperature and contact with building materials can push it into Category 2 or 3.
Water with significant contamination — enough that it could cause discomfort or illness if someone touched it or swallowed it. S500 puts dishwasher and washing-machine discharge, an overflow from the toilet bowl itself with urine but no feces, and seepage through a foundation under hydrostatic pressure in this group.
Grossly contaminated water that can carry pathogens — sewage, backups from past the toilet trap, and ground or surface water that has entered the building. S500 generally calls for porous materials that absorbed it, such as carpet cushion and insulation, to be removed rather than dried.
Classification per ANSI/IICRC S500, the industry standard for professional water damage restoration.
Water damage is not one event, it is a sequence. Each stage costs more to undo than the one before it, which is why drying starts before anything else does.
First hours
It runs along the floor and wicks upward into drywall, carpet cushion and insulation, so the wet area is already larger than the puddle you can see.
1–24 hours
Wood swells and cups, drywall softens, and anything made of pressed board or laminate begins to come apart at the seams.
24–48 hours
EPA guidance is that wet material dried inside the first 24 to 48 hours will, in most cases, not grow mold. Past that window it can, and then the job is no longer only about water.
2–7 days
Paint and wallpaper let go, joints open up, and moisture travels through wall cavities into rooms that were never touched by the original leak.
1 week or more
Once structure and finishes have held water this long, the work shifts from drying materials out to cutting them out and putting new ones back.
Mold timing per US EPA guidance on moisture and mold. The other stages vary with the material, the temperature and how much water is involved.
Drying a structure is a measured process, not a matter of pointing fans at a wet floor. Each piece of equipment does one job in that sequence.
Vacuum systems, truck-mounted or portable, that pull standing water out of carpet, cushion and hard surfaces. S500 prioritises physically removing water first, because extraction takes out far more of it, far faster, than evaporation ever will.
Low-profile blowers aimed along a wet surface rather than at it. They peel off the thin layer of saturated air sitting on the material, which is what keeps evaporation from stalling.
Air movers move water out of materials and into the air; dehumidifiers take it back out of the room. Refrigerant units condense it on a cold coil and drain it off, desiccants pull it onto a drying medium. Evaporated water that is not removed raises humidity, and dry materials can take it back on — what S500 calls secondary damage.
Pin and pinless meters read how much water is actually inside wood, drywall and subfloor. S500 sets the finish line as a dry standard — readings taken from unaffected material of the same type in the same building — not how a room looks or feels.
Temperature and relative humidity readings taken inside the drying area, outside it, and at the dehumidifier outlet. Comparing the three shows whether the setup is genuinely pulling water out of the building or just stirring it around.
A thermal camera cannot see water — it sees temperature. Wet material usually reads cooler because evaporation cools it, so the camera narrows down where water travelled behind walls and where to put a meter next.
Sheeting seals the work area and a HEPA-filtered machine holds it under negative pressure, so dust and spores leave through the filter instead of drifting through the building. IICRC S520 treats containment and HEPA filtration as standard controls when contaminated material is disturbed.
Floor mats and structural cavity drying systems move air through wall and ceiling cavities, under flooring, and into enclosed spaces such as the void beneath cabinets. The aim is to dry an assembly in place — where the category of water or the state of the material allows it.
Equipment roles per ANSI/IICRC S500; containment guidance per IICRC S520 and EPA mold guidance.
Drying in place is the goal, and it is often achievable. What decides it is the category of the water and what the material is made of — a measured judgement rather than a guess. Under ANSI/IICRC S500, porous materials that absorbed contaminated water are generally removed rather than dried, while materials wet by clean water can frequently be dried where they are.
Where an assembly has to be opened, it is opened deliberately: enough to reach wet insulation and framing, documented before anything is cut, and put back by the same company that took it out.
Restoration is stressful enough without fighting through a claim alone. Our crews document everything — photos, moisture readings, and a clear scope of work — in the format adjusters expect, and we communicate with your insurance company throughout the job. You always know what is happening and what your policy covers before work begins.

What you can see is the surface. Subfloor, wall cavities and insulation hold water long after a floor feels dry underfoot. EPA guidance is to dry water-damaged areas and materials within 24 to 48 hours, because in most cases that is what keeps mold from starting — and the only way to know a material is dry is to measure it.
By measurement, not by calendar. ANSI/IICRC S500 works from two reference points: a dry standard, which is a reasonable approximation of a material’s moisture content before the water got in, and a drying goal for the end of drying. The dry standard is commonly established by reading unaffected material of the same type in the same building, and readings are recorded as drying progresses.
Often, though not always, and it is decided by moisture readings rather than by how bad the cupping looks. Wood cups because the underside is wetter than the top, and specialty mat systems can draw that water back out through the surface. Two things usually end the conversation: water that sat long enough to delaminate an engineered plank, and contaminated water that got underneath. Sanding is the last step, never the first — a floor sanded flat before it finishes drying will crown as it dries.
Please leave it running. Drying is a continuous cycle of evaporation and dehumidification, so hours with the equipment off are hours the materials sit wet. Ask the crew to reposition or re-angle a unit if a room is impossible to sleep in, and if the running cost is the worry, raise it with your adjuster.
Usually not as a first step. EPA guidance is that sampling is generally unnecessary when mold is already visible, because the response is the same either way: fix the moisture and remove the growth. Testing earns its place in narrower situations — confirming a suspected hidden source, or documenting conditions when something is in dispute.
It can, and it is worth knowing before you file. Many homeowners policies draw a line between a sudden, accidental discharge and damage that developed gradually, and the wording varies from policy to policy. Read your own coverage and ask your adjuster directly rather than assuming it either way — and from the start, document what you found and when you found it.
