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.

When a water-related emergency strikes in the St. Louis area—be it from a burst pipe in Chesterfield, a sewage backup in Fenton, or sudden flooding in Ballwin—securing rapid and professional water extraction services is crucial to minimize damage. United Water Restoration Group of St. Louis - West is poised and ready to respond around the clock. When you call us, our expert team springs into action, utilizing advanced extraction techniques and equipment to remove standing water and start drying your property immediately. Navigating through a water emergency is overwhelming, but rest assured, our knowledgeable crew will guide you through the entire insurance claim process, providing a seamless transition from crisis to recovery. Our commitment to using industry-leading methodologies and equipment ensures that your property's integrity and safety are quickly restored, safeguarding your home and health from further complications.
Water extraction is a critical first step in addressing water damage incidents. Utilizing powerful pumps and vacuums, our trained technicians remove standing water from affected areas, a process fundamental to preventing escalation of damage. The extent and method of extraction often depend on the class of water loss—ranging from Category 1, involving clean water from a broken pipe or supply line, to Category 3, which includes severely contaminated black water such as that from sewage backups and requires extensive sanitization measures.
After we handle the immediate removal of water, the focus shifts to structural drying to stabilize and preserve your home’s infrastructure. This vital step involves deploying strategically placed air movers and low-grain refrigerant dehumidifiers to draw out moisture from walls, floors, and the air itself, effectively controlling moisture levels and humidity within your property. Our team conducts thorough moisture mapping and meter readings to ensure no hidden pockets of moisture are left behind. We also employ thermal imaging inspections when necessary to locate water that may not be visible to the naked eye, ensuring comprehensive coverage of affected areas.
By adhering to the IICRC S500 standard, we ensure a meticulous and systematic approach to the extraction and drying process, protecting your property from secondary damage like mold growth and structural instability that can occur if moisture is not properly eradicated. Our detailed protocol not only secures your home against immediate threats but also fortifies it against potential long-term complications.
In the St. Louis area, properties often confront several common sources of water damage—from leaky supply lines in Ballwin to sump pump failures in Chesterfield, and persistent subfloor issues in Maryland Heights. Understanding these local nuances enables us to provide targeted and effective solutions that expedite recovery efforts, minimizing disruption to your daily life. Flood cleanup is a recurrent challenge, often exacerbated by severe storms or sudden downpours typical of our region’s climate.
Standing water poses significant risks including damaging wet drywall, causing hardwood floor cupping, and enabling water to wick up walls and seep into baseboards. Homes with crawl spaces or older plumbing systems are particularly vulnerable to hidden leaks or backups, especially if preventive maintenance is lacking. Addressing these specific issues requires immediate action to counteract long-term harm and includes the deployment of effective emergency mitigation measures. For instance, containment barriers and negative air machines help protect unaffected areas, maintaining proper air quality and controlling the spread of moisture.
Our deep familiarity with the local environment and its challenges—including swiftly shifting weather patterns and aging infrastructure—means we can preemptively identify potential water damage issues, delivering pre-emptive measures and quick responses. This strategic foresight not only resolves immediate damage but also helps prevent future incidents, ensuring your property remains resilient against the elements.
Dealing with insurance during a water emergency can be daunting, often adding stress to an already overwhelming situation. At United Water Restoration Group of St. Louis - West, we aim to demystify the insurance process for our clients, providing support every step of the way. Immediately after your initial call, we conduct a thorough assessment of the water damage, gathering vital information to help us prepare a detailed scope of work in line with industry-standard estimating practices. This includes documenting damage with photos and compiling daily drying logs backed by precise moisture meter readings.
Armed with this comprehensive documentation, we assist in compiling extensive reports for your insurance adjuster. Our staff maintains open lines of communication with both you and your adjuster, ensuring all parties are informed of progress and any additional requirements. We advocate on your behalf, clearly explaining the categories and classes of water damage affecting your claim, which streamlines the approval process and ensures maximum coverage for restoration efforts.

Call (314) 455-5900How 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
Once we reach your property, our first priority is conducting a detailed evaluation to determine the scale and source of water damage. Simultaneously, we perform a safety check to establish a secure environment, addressing any immediate hazards such as electrical risks or structural integrity issues.
Step 02
Swift water removal is paramount. Utilizing industrial-grade pumps and vacuums, we begin extracting standing water without delay. This essential step significantly reduces the potential for water to wick into walls and structural elements, mitigating the immediate risk of extensive damage and facilitating faster drying.
Step 03
With the bulk of water removed, we use advanced moisture meters and thermal imaging technology to meticulously map residual moisture. This allows us to target our drying efforts precisely where needed, ensuring no hidden dampness remains that might foster mold or cause further structural degradation.
Step 04
Deploying air movers and dehumidifiers in strategic locations, we focus on thorough moisture removal. Continuous monitoring, through daily drying logs and relative humidity assessments, informs adjustments to our techniques to optimize drying efficiency and effectiveness across all affected areas.
Step 05
Post drying, we apply rigorous antimicrobial treatments to prevent microbial growth. Before wrapping up, extensive final checks confirm adequate drying and sanitization, ensuring your environment is safe and habitable. We then prepare comprehensive documentation to assist you with the insurance claim process.
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.
