Dunedin sits on the Gulf side of north Pinellas, with Clearwater to the south and Palm Harbor to the north. More than half of its 22.94 square miles is water. That shapes every water damage job here. 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 airport. From there it is roughly 14 to 16 miles northwest to Dunedin, about 25 to 30 minutes by way of the Bayside Bridge. We answer the phone at (727) 263-3778 around the clock, because a slab-on-grade house in a humid climate does not wait politely for business hours. The work follows the IICRC standards — S500 for water damage, S520 for mold. What makes a Dunedin job particular is the housing: 1910s Craftsman bungalows near downtown with longleaf pine floors, 1920s Mediterranean Revival in stucco and barrel tile, and the post-war concrete block that fills most of Pinellas. Each one loses water differently, and each one dries differently.
- Available 24/7 across Dunedin, Clearwater, Palm Harbor and all of Pinellas County.
- Work follows IICRC S500 for water damage and S520 for mold.
- Moisture mapped room by room, with reference readings from dry areas.
- Daily temperature, humidity and material readings logged at the same points.
- Containment and HEPA negative air before any demolition begins.
- Photos, logs and material inventory documented for your insurance file.
- Roughly 25 to 30 minutes from our Clearwater office via the Bayside Bridge.

Where the water goes in a Dunedin house
Water on a slab does not soak in and disappear. It spreads flat, finds the lowest line, and travels under things. In a concrete block house — the standard build here since the 1950s — the drywall does not touch the block. It hangs on furring strips, so there is a narrow void behind every wall. Water wicks up the paper face, and the cavity behind it stays wet after the surface reads dry on a meter. That void is why we cut and pull baseboard instead of aiming a fan at the room. Older Dunedin homes often sit on terrazzo. In tract construction the terrazzo was poured across the whole footprint and ground smooth before the partition walls went up, so the floor runs continuously beneath the walls. Water follows it from the kitchen into the hallway and the back bedroom without ever crossing a doorway.
The bungalows, and what fails first
Dunedin held back redevelopment, which is why so much of the old stock is still standing where it was built. Craftsman bungalows from the 1910s through the 1930s: low-pitched gable roofs, wide eaves, exposed rafter tails, deep front porches, longleaf pine floors and built-in cabinetry. Those materials are the reason the work has to be careful. You cannot order replacement longleaf pine. Plaster over wood lath fails from behind rather than in front. The lath swells as it takes on water, and the swelling breaks the plaster keys that hold the wall together — so a ceiling can look sound while it is quietly letting go. Lime plaster tolerates a short soaking better than gypsum board but returns to condition slowly, so we run a longer, gentler drying schedule on these houses. And a pre-1940 bungalow may sit on masonry piers over a crawl space rather than a slab. We check that before anything else.
Rain, wind and what 2024 proved
St. Petersburg's gauge averages 53.62 inches of rain a year, and nearly two-thirds of it falls between June and September. July brings 9.73 inches; November brings 1.64. The National Weather Service dates the rainy season May 25 through October 10, and the storms that fill it are sea-breeze storms — the peninsula is narrow enough that the breeze off the Gulf and the breeze off Tampa Bay collide inland and build. Wind does its damage without touching the roof covering. Sustained winds near 90 miles an hour drive rain through soffit and gable vents until attic insulation is saturated and a ceiling lets go. Soffits were not required to hold the same wind pressure as windows until a 2006 code supplement, and 86.8 percent of the county's housing predates 2000. Then there is surge. Helene came ashore more than 150 miles north of here in the Big Bend and still produced flooding Dunedin had no record of matching.
There is no dry season for mold here
Up north, a wet building gets a stretch of dry air to help it along. Here it never does. Relative humidity across the Tampa Bay area averages about 74 percent, and no month averages below 69 percent — not even April, the driest stretch of the year. Summer dew points sit above 70 degrees for months at a time. St. Petersburg records muggy days in every month on the calendar, and the normal overnight low never drops below 52.5 degrees. So the outside air is never dry enough to dry a building on its own. EPA guidance is to keep indoor relative humidity below 60 percent and ideally between 30 and 50, and the air outside here exceeds that essentially every day of the year. EPA also says material dried within 24 to 48 hours usually will not grow mold. Opening the windows in Dunedin in August does not start that clock. It works against it.
The first hour on site
First question is where the water came from, because that decides everything after it — the category of water, the scope, and which insurance policy is in play. Second question is how far it went, and the answer is almost always farther than the stain. We sweep with a non-penetrating meter first, then confirm with pin readings in the materials that matter, and we take reference readings in a dry part of the same house so there is something to measure against. A thermal camera shows the cool line where evaporation is happening behind paint. Then it gets written down: room by room, wall by wall, how high the moisture runs and where it stops. Block walls and plaster and slab-bonded floors are slow, dense materials — S500 calls that a Class 4 loss, specialty drying — and they are common in Dunedin. Photographs come before anything is moved.
Extraction, and what actually comes out
Every gallon pulled out mechanically is a gallon the dehumidifiers do not have to lift into the air, so extraction runs first and runs long. On carpet that means weighted extraction, passing over the same lane until the head comes up dry. Over a slab it means chasing the water where it went — under plank flooring, under the toe kick, into the bottom plate of the wall. What comes out depends on where the water came from. A supply line break is clean and mostly stays clean. Surge is different. When Helene pushed water into Dunedin homes that had never flooded in the city's records, what came inside carried sand, sediment and whatever the streets and storm drains held. The IICRC's position is that a weather event does not automatically make water Category 3 — that call is made by inspection — but surge water usually is, and porous materials that absorbed it are removed rather than dried.
Containment, and why the plastic goes up
Demolition makes airborne debris, and a wet house that already has growth will spread it around the moment a saw starts. So the affected area gets sealed off — sheet plastic, a zippered entry, and an air scrubber running HEPA filtration under negative pressure, so air moves into the work area and not out of it. In a small bungalow, containment is also what keeps the rest of the house livable. There is a legal line here too. Florida licenses mold assessors and remediators as individuals, not companies, and the license requirement attaches to jobs larger than ten square feet — roughly a three-by-three patch, which is also EPA's do-it-yourself ceiling. Ask for the license number of the person on your job. Florida also separates the two roles: with a narrow exception for certified Division I contractors who disclose your right to competitive bids, the company that assesses your mold generally cannot be the company that removes it.
Drying, and the numbers taken every day
Equipment is set to a target, not a guess. We read unaffected material elsewhere in the same house to establish what dry means here, then run air movers and dehumidifiers toward it. Every day, at the same points, we log temperature, relative humidity and the moisture content of the materials on the map. Drying is a curve and the curve has to move. When it stalls, the setup changes: more airflow, injection into a wall cavity, the covering comes off the floor. A block-and-plaster bungalow near downtown Dunedin takes longer than a 1990s house, and the daily log is what proves it is still progressing. Slabs get particular scrutiny. The seasonal water table in the soils under much of the county sits within six to eighteen inches of the surface for months, and slabs poured before vapor barriers were routine re-wet from below — dry at the surface, and still able to ruin a floor laid a week later.
Cleaning, sanitizing and the smell that lingers
Odor is information. A house that still smells after the equipment comes out is telling you something is still wet, or something that was never cleaned is still there. Fragrance covers the signal without fixing the cause, so we work the other direction: remove what cannot be cleaned, HEPA-vacuum and detail-clean what can, then apply an antimicrobial to surfaces that have already been cleaned rather than over the top of soil. In a bungalow with original pine floors and built-ins, more cleaning is done by hand. For mold work, S520 sets the target plainly. Areas at Condition 3, visible growth, and Condition 2, settled spores, are brought back to Condition 1 — the normal fungal ecology of an unaffected building. Nobody can deliver a sterile house, and a company that promises one is selling something. What can be delivered is verification, done by an assessor who is not the remediator, and a moisture source that has actually been fixed.
Documentation, and which policy pays
Two kinds of water damage can look identical on a wall and belong to different policies. Federal law defines flood to include the overflow of tidal waters, so storm surge is a flood claim, and a standard Florida homeowners policy excludes it. Wind is the other side: Florida statute covers interior rain damage when the windstorm first opened the building. Same wet drywall, different carrier, and the deciding evidence is the entry path and the water line — which exist only if somebody photographs them on day one. So we document as we go. Photographs before demolition, the moisture map, daily readings with dates, an inventory of what was removed and why, and equipment counts and run times. You get that file whether or not there is a claim. What we do not do is take an assignment of your benefits — Florida ended that for residential policies issued on or after January 1, 2023. You stay the claimant.
A few things worth knowing before you need them. Florida hurricane deductibles are a percentage of your dwelling limit, not of the loss — five percent on a $400,000 limit is $20,000 before the carrier pays anything — and the deductible applies once per calendar year per insurer, not once per storm. A property claim must be reported within one year of the date of loss, and for a hurricane that date is the day of landfall, not the day you found the damage; supplemental claims run eighteen months. Your carrier has its own clock: seven days to acknowledge, thirty to inspect, sixty to pay or deny. If a claim stalls, Florida's Department of Financial Services runs a free mediation program for residential disputes and the insurer pays for it. And if repair costs reach half your structure's value, the FEMA substantial damage rule comes into play — Dunedin and the county both ran assessment programs after 2024, and it is worth asking early.
