Appliance leaks come from washer hoses, dishwasher supply and drain lines, refrigerator ice-maker lines and similar fittings. Shut off the supply valve, unplug the appliance if the floor is dry, and call. Port St. Lucie Water Damage Restoration answers 24/7, and a crew is dispatched as fast as one is available to extract water and dry floors, cabinets and walls.
Appliance leaks are the quiet kind of water damage. A washing machine hose does not burst on the news; it lets go on a Tuesday while you are at work, runs for hours and leaves a floor plan wet by the time you open the door. The dishwasher and the refrigerator are the same story on a smaller scale: a slow seep from a supply line or a drain connection that goes unnoticed for weeks behind a toe-kick or a cabinet.
Single-storey slab homes are common in Port St. Lucie, and they change how appliance leaks play out. Water cannot drain down through a floor, so it spreads sideways across tile, laminate or luxury vinyl, finds the baseboards and wicks into the bottom of the drywall. A leak in a laundry room can reach the hall and a bedroom without stopping, and a kitchen leak soaks cabinet bases and the subfloor edge.
This page covers extraction, drying and what to expect on the cleanup. The crew does not repair or replace appliances or plumbing: a licensed plumber or an appliance technician handles the hose, the valve or the machine. What the crew does is remove the water, check where it went, dry what can be dried and document the readings.
Do not stand in water to unplug an appliance, and never touch a wet outlet or power strip. If the water has reached the panel, a plug or an outlet, stay out and call from a dry spot.
The shut-off valve behind the washer or under the sink is closed, and the appliance is unplugged only if the cord and outlet are dry. The crew checks for wet outlets and stays out of areas where water has reached wiring.
Wet vacuums and pumps take the water off the floor, and rugs and carpet are lifted. In a kitchen the crew may remove toe-kicks so water trapped under the cabinets can be reached.
A moisture meter and a thermal imaging camera show where the water went, including under flooring, into wall bottoms and into cabinet bases. The wet area is almost always larger than the visible puddle.
Carpet pad, soaked baseboard, wet insulation at the wall bottom and some laminate or particleboard cabinet parts may be removed with your approval. Tile and sealed hard surfaces usually stay.
Air movers and dehumidifiers run until readings match a dry reference in your own home. Floors under click-lock planking and the cavity behind cabinets take the longest.
The crew leaves you with readings and photos you can share with your insurer. Repairs to flooring, cabinets and drywall are quoted separately, and the appliance or plumbing work goes to the right trade.
Appliance leak cost depends on the category of the water, the area wet and the days of drying. Washer and dishwasher drain water counts as gray water, which costs more to clean than clean supply water.
| Job | Typical range | What it includes |
|---|---|---|
| Clean water (Category 1) cleanup, per sq ft | $3–$4 | Typical estimate for supply-line leaks |
| Gray water (Category 2) cleanup, per sq ft | $4–$6.50 | Typical for washer or dishwasher drain water |
| Air mover, per unit per day | $25–$50 | Typically several per room |
| Commercial LGR dehumidifier, per unit per day | $75–$150 | One unit for a small area, more for several rooms |
| Structural drying, two to three rooms (Class 2) | $2,000–$5,000 | A hallway leak that reached bedrooms often lands here |
| Whole-job water damage examples in Florida | $1,200–$5,500 | Typical examples; your job may fall outside |
These are typical estimates for St. Lucie County in 2026, not a price list. The crew explains the emergency-stage price and you approve it before work starts. Appliance repair and flooring replacement are priced separately.
Washing machine supply hoses and dishwasher lines are among the most common sources, followed by refrigerator ice-maker lines and water-filter fittings. They fail at couplings, from age, from vibration or from a loose connection. A slow leak can run for weeks before the floor shows it.
The hose behind a washer is under full line pressure whenever the valves are open. Rubber hoses harden, crack and bulge, and the coupling at the valve is the usual point of failure. Braided hoses last longer than plain rubber, but they too fail where metal meets the hose.
Dishwasher lines are less dramatic, but they hide better. The supply line and the drain hose sit in the dark cabinet space, and a drip that never reaches the visible floor soaks the cabinet base and the subfloor instead. By the time the toe-kick swells, the damage is already spread.
A plumber or an appliance technician can replace hoses and fittings. If a hose is old, replacing it before it fails is the cheapest water damage prevention in the house, and shutting the washer valves when you go away is a good habit.
On a slab, water cannot drain downward, so it moves sideways across the floor until it meets a wall, a threshold or a low spot. Single-storey layouts put the laundry, kitchen and bedrooms on one level, so a leak in one room can reach the next in minutes.
A single-storey block-and-stucco house has rooms in a row, with doorway thresholds at slab level or only slightly raised. Water crosses a doorway easily, then runs along the baseboards. It does not need much depth to wick into drywall, and even a thin film soaks into the bottom inch or two of a wall.
The flooring decides how bad it gets. Tile with a sealed slab underneath tolerates water, and the drying focuses on grout, baseboards and the wall bottom. Laminate and vinyl plank are more vulnerable, because the water slips under the seams and sits against the underlayment. The crew may lift planks to dry beneath them.
That is why the first visit includes moisture mapping beyond the room with the appliance. A dry-looking hallway can be wet at its base.
Gray water carries soap, food residue and bacteria, so it is treated as Category 2 water. It is not sewage, but porous materials it soaked, such as carpet pad and baseboard, are usually removed instead of dried in place. Hard floors are cleaned before drying starts. Wear gloves and avoid touching it with bare skin.
IICRC terms group water into three categories. Category 1 is clean supply water. Category 2, gray water, can make people sick if swallowed and contains contaminants that feed microbes. Category 3, black water, includes sewage and floodwater. A washer drain overflow or a dishwasher backup is typically Category 2.
Category 1 water can slip into Category 2 if it sits. A clean supply leak that runs over a dirty floor, or soaks into carpet for a day or two, is treated with more caution than a fresh one. The category is recorded early because it decides which materials stay.
None of this is a reason to panic. It is a reason to avoid wading through the water with bare feet, to keep children and pets out of it and to let the crew treat the surface before drying.
Shut the appliance valve and watch the water meter or the nearby floor. If the leak was at the appliance, a closed valve ends it. If water keeps appearing, the leak is in a wall or under the slab, and a plumber should check it before drying continues, because drying a floor that keeps getting wet wastes the work.
A simple test is to turn off every fixture and appliance and look at the meter. If the dial still moves, water is escaping somewhere, which may be a different line than the one you found. A moisture reading that rises between visits points the same way.
Drying does not fix a leak. If the source is still active, the crew can set up equipment but the readings will not come down, and it is better to pause drying until a plumber has fixed the line. The slab leak page covers the case where the leak is under the floor.
A supply hose that lets go puts clean water on the floor under line pressure, and a drain overflow adds gray water with detergent and lint. Laundry rooms often back onto a hallway wall, so water reaches the next rooms quickly.
Slow seeps run under the cabinet and into the subfloor edge for weeks. The damage hides behind the toe-kick and shows up as swollen cabinet bases and cupped flooring at the dishwasher.
A small fitting at the back of a fridge can drip behind it for a long time. Flooring that sits beneath the appliance may be soaked without a visible stain until you move the unit.
Port St. Lucie has a lot of single-storey slab homes, from the 1960s and 1970s General Development lots to newer communities like St. Lucie West and Tradition. In a house like that, the laundry is often a room or closet off the garage or hallway, and the kitchen is a few steps away. That tight layout is why a single hose failure can wet most of the floor plan.
Humidity makes slow leaks worse. In Port St. Lucie the summer air is humid for months, and wall bottoms and cabinet bases that stay damp do not dry on their own. A small drip behind a dishwasher can keep the toe-kick wet for weeks, and mold can start in damp materials even when the visible area looks fine.
If you rent or live in a townhome, check who owns the appliance and the line, and tell the landlord or the association in writing. Leaks in multi-unit buildings reach neighbors, and the condo and commercial page explains how that is handled.

A homeowners policy often covers sudden and accidental water damage, and usually not damage from long-term leaks or wear. Whether yours does depends on the cause and your policy wording. The crew can give you moisture readings and photos, and your insurer decides coverage.
Only after the supply is off and the cord is unplugged from a dry outlet. Washers and refrigerators are heavy, and pulling them across wet flooring can tear it. The crew can move them safely if the floor under them needs drying.
Often a few days, because water gets under cabinets and into the subfloor edge. The crew uses air movers and dehumidifiers, may remove toe-kicks to reach the cavity and re-checks readings until the materials are dry. The exact number of days depends on the meters.
Sometimes. If water got under the planks and they have swollen or lifted, they usually cannot be saved. If the flooring can be lifted, dried and reinstalled, it may be. Tile usually survives with drying. The crew explains which applies before anything is removed.
A licensed plumber or an appliance technician repairs the line, valve or machine. The restoration crew does not do plumbing or appliance repair. It extracts the water, dries the home and documents the damage.
It is not too late, but the damage is likely larger and mold becomes a real concern. EPA guidance suggests drying within 24 to 48 hours as a guideline, and mold can start before then. Call, get readings and ask about a mold assessment if there is a musty smell or visible growth.
