Flood damage cleanup removes standing water, hauls out soaked flooring and drywall that cannot be saved, cleans and dries the structure and documents the loss. Floodwater is treated as contaminated Category 3 water. A crew serving Celina and Collin County is dispatched as fast as one is available, and phones are answered 24/7.
If water from outside is coming into the house, get yourself and your household out of it first. Do not wade through standing water to reach a breaker panel, and do not walk through it with the power on. Floodwater can carry sewage, fuel and yard chemicals, so treat anything it touched as contaminated until a crew says otherwise. Shut off the water at the main valve only if the valve is dry and easy to reach.
Most homes around Celina sit on concrete slabs, with no basement to fill. That changes how flood damage looks here. Water that gets over a threshold or through a garage door spreads across the whole ground floor at once, soaks the bottom of every wall and finds the cabinets, baseboards and flooring in one pass. A single-storey house can be wet in every room from a few inches of water.
This page covers what flood cleanup involves, why floodwater is handled differently from a supply-line leak, how heavy rain and creek flooding reach north Collin County homes, and what the cleanup and the repairs afterward usually cost. Stopping water at the source, such as a failed pipe, is a plumber's job. Pulling water out, removing what cannot be saved and drying the structure is what a restoration crew does.
Floodwater is classed as Category 3 because it has crossed ground, roads and drains before it reached your house. It can carry soil, bacteria, sewage and chemicals. Crews wear protective gear, remove porous materials the water touched and clean the structure, instead of simply drying it.
In the S500 water damage standard, published by the industry body IICRC, water is sorted into Category 1 (clean supply water), Category 2 (gray) and Category 3 (black). Rising floodwater and sewage sit in Category 3. IICRC is not a regulator, and the S500 is a guide that crews follow; it is not a Texas law.
The practical difference is what happens to the materials. A wet drywall wall after a supply-line leak may be dried in place. A wall that wicked floodwater is usually opened, because drying alone does not clean it. Carpet and pad that sat in floodwater are normally removed, and the slab beneath is cleaned before anything is dried.
Spring storms are the usual cause. Heavy rain can fill roadside ditches, culverts and street drains faster than they empty, and creeks such as Wilson Creek in McKinney can rise in a storm. Water then pools against slab-on-grade homes and runs into garages and under doors.
Celina's 2017 master drainage study found that the original town and downtown drain through roadside ditches and culverts under driveways, with curb-and-gutter storm sewers planned for the future. Newer subdivisions are built to a stormwater design standard, and Celina has earned a Gold designation under the regional iSWM program, which includes designing for fully developed conditions. That design does not make a house immune in an intense storm.
Farther east, McKinney has had five water rescues on two roads since 2015, and the city approved a flood-warning system for five points. Wilson Creek runs through McKinney and meets the East Fork of the Trinity River at Lavon Lake. Check FEMA's flood map for your own address; this page does not state flood-zone designations for any street.
The wet months for storms in Collin County run roughly March through June, and DFW Airport records about 37 inches of precipitation in a typical year, according to the National Weather Service in Fort Worth. That station is about 35 miles south of Celina, so treat it as a regional guide rather than a local measurement.
A standard homeowners policy usually does not cover flood. Flood insurance is a separate policy, through FEMA's National Flood Insurance Program or a private insurer, and it generally has a 30-day waiting period. Your insurer decides coverage under your own policy, so read it or ask your agent before assuming anything.
Wind-driven rain through a damaged roof is a different matter from rising water at the ground. The first may fall under your homeowners policy, while the second is typically a flood event. If both happened in the same storm, an adjuster will want to know which water came from where, so take photos of the water line, the roof and the garage before anything is moved.
A restoration crew can give you moisture readings and photos for your claim, and it can describe what water was in the house and what it touched. It cannot tell you what your policy will pay. If a claim is denied or delayed and you cannot resolve it, the Texas Department of Insurance takes consumer complaints about insurers.
Stay out of standing water, stop using affected electrical circuits and take photos of the water line and damaged items before anything is moved. Lift items off the floor if it is safe, open interior doors for air flow, and keep children and pets away from contaminated areas. Then call for help.
Do not run a household vacuum on standing water, and do not try to dry out a flooded room with a space heater or fan plugged into a wet circuit. If the water reached outlets, assume the circuit is unsafe until it has been checked.
Take photos before any cleanup. Wide shots of each room, close shots of the water line on walls, and photos of ruined contents are all useful when you file a claim. Write down anything you throw out. Keep samples of flooring if your insurer asks.
Do not enter a flooded room if the water is near outlets, appliances or the electrical panel, and do not drive or walk through flooded roads. If you smell gas, leave the house and call your gas utility from outside.
The crew checks for electrical hazards, wet outlets and slippery or contaminated surfaces, and sets up protective gear before anyone works in the water. Power to wet areas stays off until it has been checked.
Pumps and wet vacuums pull water off the slab and out of low areas such as a garage. Moving it fast matters because floodwater can get worse the longer it sits.
Soaked carpet, pad, insulation and drywall that wicked floodwater are cut out and bagged. Walls are usually cut a set height above the waterline so the cavity can open and dry.
Slab, framing and hard surfaces are cleaned because the water carried soil and contaminants, then treated with a cleaner suited to the material. Contents are sorted into keep, clean and discard.
Air movers and dehumidifiers run while moisture meters and thermal tools track walls and floors until readings reach the drying goal, which is how the crew knows when to stop.
You get photos and moisture readings to share with your insurer, and repairs such as new drywall, base and paint are quoted separately after the structure tests dry.
Intense spring storms can overwhelm roadside ditches, culverts and storm drains faster than they empty. The result is shallow water at slab level that runs into garages and through door thresholds. It is usually a short-lived event, but the water is still surface runoff and carries whatever it crossed.
Properties near a creek or in a low spot can take water when the channel fills. Around McKinney, Wilson Creek flows toward Lavon Lake and has been the source of flooding rescues on local roads. Water that reaches a house this way is moving, carries silt and is handled as Category 3.
A garage is often the lowest, most exposed room, with a door that only seals so well. Water that enters here can run under the interior door and into the house, and stored boxes, tools and appliances sit directly in it. Crews treat the garage slab and the adjoining rooms as one job.
Sometimes heavy rain overwhelms a sewer line and pushes water back up inside, which is a different problem from water coming in from the yard. If waste water came up through a drain, the sewage cleanup page covers the extra steps involved.
Flood jobs are priced by how many square feet were wet, how many days of drying the structure needs and how much material has to be removed. Contaminated Category 3 water costs more per square foot than clean water because of the protective gear, disposal and cleaning involved.
| Job | Typical range | What it includes |
|---|---|---|
| Whole-job water damage restoration (Greater DFW range) | $1,200–$5,000 | A wide range; a large flood job can sit above it |
| Category 3 (black) water, per square foot | $7 and up | Floodwater is normally treated at this level |
| Water extraction, limited loss | $500–$1,500 | Shallow standing water on one level |
| Drying and dehumidifying | $700–$2,000 | Equipment, setup and monitoring |
| Extraction plus drying, several rooms or structural materials | $5,000–$15,000 or more | A multi-room slab-level flood often lands here |
| Drywall replacement, finishing included (per sq ft) | $3–$8 | Repair work after drying, quoted separately |
These are typical ranges for Collin County in 2026, confirmed on site before any work starts. Insurance coverage for a flood is a separate question from the price, and your insurer decides it under your own policy.

Most of Celina and the surrounding growth towns are slab-on-grade, which means flood water goes straight into living space rather than into a basement. There is no lower level to take the first inches. The same is true in Light Farms, Windsong Ranch, Craig Ranch and Trinity Falls, so a few inches of water outside can become a whole-floor job inside.
In older districts such as Downtown Celina and Historic Downtown McKinney, flood cuts raise a different issue. Older buildings can contain asbestos or lead paint, and homes built before 1978 fall under the EPA lead rules for renovation work. Ask before any walls are cut in an older building.
Many rural addresses around Weston, New Hope, Aubrey, Krugerville, Tioga and Gunter use private wells and septic systems. Floodwater that covers a septic field or well head is a separate problem from water in the house, and the county or your well and septic professional should be part of the conversation.

A standard Texas homeowners policy often covers sudden and accidental water damage, such as a burst pipe, and usually does not cover long-term leaks, flood or sewer and drain backup without an added endorsement.
A garage slab can dry on the surface, but the walls, stored items and the door seal behind the garage wall stay wet longer than you can see. Floodwater is also contaminated, so the slab should be cleaned, not only dried. A crew can measure what is still wet.
Often some of it, yes. Drywall that wicked floodwater is usually cut out a set height above the waterline so the wall cavity can be cleaned and dried. How much comes out depends on how high the water rose and on what moisture readings show.
Extraction can be quick, but cleaning and drying usually take several days, and the repair work afterward takes longer. The drying stops when readings reach the goal, not on a calendar date. The crew tells you the plan on site.
Yes. A burst supply pipe releases clean water, while floodwater comes from outside and is treated as contaminated. That changes which materials can be dried in place and which must be removed. The burst pipe page covers the clean-water case.
No. Drainage, grading and plumbing repairs are separate trades. The crew removes water, cleans and dries the structure and can help tarp or board up an opening. A licensed plumber handles pipe repair, and a landscaper or engineer handles drainage.
