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.

Water damage in Pinellas County rarely announces itself politely. A supply line lets go behind a vanity, a condensate drain backs up into a hallway closet, or a storm pushes bay water across a yard and under a door. The puddle you can see is the smallest part of it. United Water Restoration Group of Pinellas County works out of 3734 131st Avenue N, Unit #12, Clearwater, FL 33762, in the Gateway area beside the St. Pete-Clearwater airport. That address is mid-county on purpose. Pinellas Park starts at our door, downtown St. Petersburg is fifteen to twenty minutes south on I-275, downtown Clearwater about the same to the northwest, and Largo, Seminole and Dunedin sit inside a half-hour run, Palm Harbor a little beyond it. Someone answers (727) 263-3778 at any hour, because the clock is the job. The EPA puts the window for drying wet materials at 24 to 48 hours before mold becomes likely, and the air here does not help you meet it. We work to the IICRC S500 standard for water damage and S520 for mold. Our neighbors have rated us 4.93 stars across 169 reviews.
The first question is where the water came from. Not because we are stalling, but because the answer sets up the whole job. A broken supply line under a sink is Category 1 water under the S500 standard, sanitary at the source. Discharge from a washing machine or a dishwasher is Category 2. Water that rose out of Tampa Bay, came in off the Gulf, or backed up through a sewer line is handled as Category 3, grossly contaminated, though we confirm that by inspection rather than assuming it. The IICRC consensus body made exactly that point in a March 2026 position statement: a weather event does not by itself make water Category 3. You gather information, then you go look.
Second question, how long has it been wet. Category 1 water does not stay Category 1. It degrades with time, temperature and whatever it touches, and a closed-up house here in August supplies plenty of all three.
Third, what is the building. Block or frame. One story, or block downstairs and frame above, which is the common two-story compromise in this market and means two different drying problems under one roof. Slab, or the pier foundation and crawl space you still find under a pre-1940 bungalow in Historic Kenwood or Dunedin. Tile, carpet, plank flooring, or something laid over terrazzo.
Then we tell you what to do in the next ten minutes. Close the valve, or the meter at the street if you cannot find the valve. Kill the breaker to the affected area if water is near outlets. Leave the air handler off if the system took water. Photograph everything, including the high-water line on the wall, before anyone moves anything.
Then we drive. Pinellas Park is minutes away. St. Petersburg and Clearwater run fifteen to twenty. Palm Harbor, the farthest, is about half an hour up the Bayside Bridge and US 19.
Walk into a wet Pinellas house and the visible damage is misleading. Most single-family homes here are concrete block with stucco, and in a block house the interior drywall is not attached to the block. It hangs on wood or metal furring strips, which leaves a narrow concealed cavity running the height of the wall. Water gets into that cavity and a surface moisture meter reads nothing. Meanwhile the block itself holds moisture and keeps handing it back to the drywall for days after the leak is fixed. That one detail is why we pull baseboard and why flood cuts exist, and it is why jobs closed too early come back as mold.
So the inspection is physical. Penetrating meters into framing and drywall. A thermal camera to find the temperature signature of evaporation. Base trim off. Every reading compared against dry material elsewhere in the same house. We map how far the water traveled, because it travels further than people expect. There is no basement for it to collect in. Instead it runs flat: under cabinet toe kicks, beneath plank flooring and into the bottom plate of the wall, and in plenty of 1950s and 1960s houses straight under the partition walls, because the terrazzo was poured across the entire footprint before those walls were built on top of it. A floor like that cannot be sectioned off room by room.
We also classify the loss. S500 rates a loss Class 1 through Class 4 by how hard it will be to dry. Class 4 is the specialty case, the low-porosity materials that hold water tightly: block, plaster, terrazzo, hardwood, lightweight concrete. In this county Class 4 is not exotic. It is ordinary. A two-story house with block below and frame above can carry two different classes at once, which changes the equipment plan before anything gets plugged in.
Standing water comes out first, with truck-mounted or portable extraction, and on carpet with a weighted head that presses water out of the pad instead of skimming the surface. Extraction is the cheapest drying you will ever buy. Every gallon pulled out mechanically is a gallon the dehumidifiers never have to take out of the air.
Then the harder conversation, which is what leaves the house. Category and class drive that, not preference. Clean water caught early saves a great deal: carpet can often stay down, drywall often stays up, cabinets can be dried from behind. Category 3 water changes the math. Anything porous it touched goes out, including pad, most carpet, wet insulation, particleboard cabinet bases, and drywall up to a cut line marked above the water. On a block wall we cut to a clean height and remove the material in the furring cavity so the block can be cleaned and dried rather than sealed up wet.
Surge work in places like Shore Acres, Clearwater Beach or the Baywood Village area of Palm Harbor brings its own mess. Silt, debris and whatever the water carried through the neighborhood all come out before any drying equipment goes in, because drying a dirty structure just puts it into the air.
There is genuine good news on older floors. Terrazzo is essentially non-porous and survives being soaked. What fails is whatever was glued on top of it, sheet vinyl or engineered plank or carpet adhesive, delaminating off a slab that is still wet underneath. The terrazzo below is usually salvageable and sometimes worth uncovering. Plaster and lath, common in Historic Kenwood, Roser Park and the older Dunedin bungalows, needs the opposite of speed. Wet lath swells and breaks the plaster keys from behind, so those walls get a slower schedule and careful hands.
Opening the windows is not a drying plan in Pinellas County. Relative humidity in the Tampa Bay area averages about 74 percent across the year, and even the driest month averages 69 percent. Summer dew points sit above 70 degrees for months at a stretch. The EPA's guidance for indoor relative humidity is below 60 percent, ideally 30 to 50. Outdoor air here runs above that essentially every day of the year, so the first physical step is to close the affected area off and turn it into a controlled drying chamber.
Inside that chamber the work is arithmetic. Refrigerant dehumidifiers pull grains of moisture out of the air. Air movers put energy into wet surfaces so those surfaces give the moisture up. Containment keeps the two from fighting the rest of the house. Where the air cannot reach on its own, we send it: cavity drying systems push dry air behind the furring strips, and floor mat systems pull moisture up through hard surfaces. The HVAC system gets addressed too, because a unit that took water will otherwise redistribute it.
We take psychrometric readings on every visit and log them. Temperature, relative humidity, grains per pound, and moisture content in the actual materials. The target is never a calendar date. It is the reading in unaffected material of the same type in the same building, and the equipment stays until the wet matches the dry.
The slab is the part homeowners underestimate. The flatwoods soils under much of developed Pinellas carry a seasonal high water table within six to eighteen inches of the surface for months of a normal year, and most houses here went up before under-slab vapor barriers were routine. A slab can meter dry on top while capillary action keeps feeding it from below. That is how a new floor buckles a week after a job everyone called finished.
A water job should end with a clean handoff and a documented file, not a handshake at the door.
First, the mold question. Where growth is present, the S520 standard describes three conditions, and the goal of remediation is returning Condition 2 and Condition 3 areas to Condition 1, the normal fungal ecology for that building. Nobody honest promises a mold-free house. That is not what the standard claims and it is not achievable. Florida's licensing requirement attaches above ten square feet of growth, which is roughly the same three-foot by three-foot patch where EPA guidance stops recommending a do-it-yourself cleanup. DBPR licenses individuals, not companies, so the useful question to ask anyone, us included, is the license number of the person actually working your house. Florida also separates assessment from remediation for twelve months in both directions, with a narrow exception for a certified Division I contractor whose remediation contract discloses your right to request competitive bids.
Second, reconstruction. A mold remediation license is not authority to rebuild. That work requires a license under Chapter 489. Once the structure is dry we hand over the scope, the photographs and the moisture logs so the rebuild starts from documented conditions instead of guesswork, and we tell you plainly who holds which license on your project.
Third, the file itself. Your carrier decides coverage, and that decision often turns on how the water got in. Interior rain damage after a windstorm first opened the building is treated differently from water that arrived at the slab. So we record the entry path, the water line, the category, the equipment deployed and the daily readings. We do not predict payouts and we do not adjust your claim. We give you evidence that is hard to argue with, and it stays yours.
A few minutes of the right first moves can save thousands in damage. Here is what to do — and what not to do — before we arrive.

Call (727) 263-3778How 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
Any hour, any day, a real person picks up — not a machine and not a national call center. You describe what you are looking at, and from that moment it stops being your problem to solve on your own.
Step 02
Our crew works out how far it has really gone, including what you cannot see behind walls and under floors. You do not have to know what to look for, or guess how bad it is.
Step 03
What comes out, what gets dried, what can be saved — those are our calls to make, and we explain each one as we go. Readings are recorded throughout, so nothing rests on you taking our word for it.
Step 04
Our own team rebuilds what came out and hands the place back finished, with everything documented the way your adjuster expects it.
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.









Two things make water damage different in this county. The first is the air. Relative humidity here averages around 74 percent and never drops below a 69 percent monthly average, well above the 30 to 50 percent the EPA recommends indoors, so nothing dries on its own. The second is what got built here and when. The median Pinellas home went up in 1976, nearly six in ten predate 1980, and the standard house is single-story concrete block on a slab, with the water table sitting six to eighteen inches under that slab for part of every year. The slab stays damp underneath after the surface meters dry. That is how a job that looked finished comes back as buckled flooring or mold behind a wall. So we move fast where speed counts and slowly where patience counts. We arrive, find the water inside the assembly, remove what cannot be saved, dry to a number instead of to a schedule, and hand over a documented file and a clean scope for the rebuild. We do that in St. Petersburg, Clearwater, Largo, Seminole, Pinellas Park, Palm Harbor and Dunedin, out of a shop at 3734 131st Avenue N, Unit #12, Clearwater. If your house is wet right now, stop reading and call (727) 263-3778. If it is not, put the number in your phone. The window for drying materials in this climate is 24 to 48 hours, and it starts without you.
From the shop on 131st Avenue N, Pinellas Park is a few minutes and downtown St. Petersburg or downtown Clearwater runs fifteen to twenty. Largo and Seminole are twenty to twenty-five west on Ulmerton Road or Park Boulevard. Dunedin is twenty-five to thirty, and Palm Harbor is about thirty-five by way of the Bayside Bridge and US 19. Traffic moves those numbers. We dispatch around the clock at (727) 263-3778.
It depends on how it got in. Federal rules define flood to include the overflow of tidal waters, so storm surge is a flood loss and sits with an NFIP or private flood policy rather than your homeowners policy. Interior rain damage is treated differently under Florida law when the windstorm first opened the building. That is exactly why we photograph the entry path and the water line on day one. We document; your carrier decides.
The floor is usually the last place to check. In a block house the drywall hangs on furring strips, leaving a cavity behind it that a surface meter never sees, and the block keeps feeding moisture back into that drywall after the leak is fixed. There is no basement here for water to collect in, so it goes sideways instead, into wall cavities and under cabinets. We meter and pull base trim to find out.
Most residential jobs run a few days, but we will not promise you a day count up front. Length is set by how much material got wet, what that material is, and how it reads. Terrazzo, block, plaster and hardwood release water slowly, which S500 calls Class 4 drying and which is ordinary in this county. The equipment comes out when readings in the wet areas match unaffected material in the same building.
Anything past about ten square feet, roughly a three-foot by three-foot patch, is where both EPA guidance and Florida licensing stop calling it a homeowner job. Florida licenses individual assessors and remediators rather than companies, so ask for the license number of the person working your house. State law also keeps the party assessing mold separate from the party removing it for twelve months, with a narrow contractor exception. We will tell you which applies to you.
No, and no Florida restoration company should say otherwise. For policies issued on or after January 1, 2023, assignment of benefits on residential property claims is void, so you stay the claimant and we bill you rather than your carrier. What we hand you is the file: photographs, moisture logs, a written scope. Report promptly, because Florida bars most claims not reported within one year of the date of loss.
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.
