Hurricane & Storm Flooding Houston — What to Do

The short answer

Safety first — stay out of standing water near outlets or the panel, and cut power only if you can do it safely. Then document everything with photos and video, get people and pets out of the water, and start removing water and contaminated contents. Treat storm floodwater as **contaminated ("black") water**: wear protection and discard porous materials it soaked. Critically, standard homeowners insurance usually does **not** cover outside flooding — that needs a separate flood policy. Call **(346) 271-7004** and we'll help you dry it out safely.

Why storm flooding is different from a pipe leak

A burst pipe is clean water you can often dry in place. Storm and hurricane floodwater is the opposite: it comes from outside, carrying sewage, chemicals, bacteria, and debris. That makes it Category 3 “black water,” which changes the rules — most porous materials it touches (carpet, pad, drywall, upholstered furniture) can’t be disinfected and have to be removed, not dried. Handling it safely means protection, aggressive removal, and disinfection, not just extraction and fans. It has more in common with a sewer backup than a supply-line leak.

The insurance surprise most Houston homeowners hit

Here’s the hard truth people learn after a storm: your homeowners policy almost certainly excludes flooding from outside. Rising water, storm surge, and bayou overflow are covered only by a separate flood policy — federal (NFIP) or private. Wind-driven rain that enters through a storm-damaged roof may fall under homeowners. Because that line decides who pays, document the water’s source and path carefully, and check both policies. Houston’s flat terrain, clay soil, and bayou network mean flooding reaches homes well outside mapped flood zones — Harvey proved that. Being “not in a flood zone” is not the same as being safe. More on the coverage line: does insurance cover water damage.

Warning signs the water went further than the water line shows

The stain on the wall is where the water stopped rising. It is not where the water stopped going.

It climbed higher than the mark:

A wet line on the drywall that keeps creeping up for two days after the water receded — wicking pulls floodwater a foot or more above the visible mark
Insulation in the cavity slumping, or the wall sounding dull instead of hollow when tapped
Baseboard and door casing swelling and separating at the miters

It went sideways and down:

Cool, heavy carpet in a room the water never visibly reached
Vinyl plank lifting at the seams, or a tile that sounds hollow underfoot
Cabinet kicks and the bottom shelf of a vanity holding standing water hours later

The contamination is doing its work: silt lines, a sewage smell, or a slick film on hard surfaces. Storm water outside a house is Category 3 water inside it, and the category does not improve as it sits.

The building is unsafe: a sagging ceiling, a buckled floor, or a submerged panel or outlet. None of those are a wait-and-see.

What to do, in order

Safety. No standing water near electricity. Cut power safely or call the utility. Watch for weakened floors and displaced hazards.
Document before you remove. Photos and video of every room and the water line — this is your flood claim.
Protect yourself. Boots, gloves, covered cuts. Keep kids and pets out of the water.
Remove water and contaminated contents. Extract, then pull soaked porous items to the curb (photograph them first).
Flood-cut and disinfect. Wet drywall comes out above the water line, insulation out, structure cleaned and disinfected.
Dry and verify. Commercial dehumidifiers and air movers until a meter says the framing and subfloor are dry. (346) 271-7004.

What to check yourself once it is safe

Boots, gloves, and nothing barehanded.

Photograph the water line before you touch anything, in every room, with something for scale in the frame.
Mark the high water line on the wall in pencil and date it. It is the single most useful measurement in the whole claim, and it disappears the moment demolition starts.
Check the wall four feet up, not just at the line. Press with a flat palm above the mark. Wicking climbs, and where it stops is where the flood cut goes.
Look under and behind the cabinets with a flashlight. Kicks and vanity bases hold water for days after the floor looks dry.
Note whether the water came in or came up. Water through a door or a wall is intrusion. Water rising from a floor drain or a toilet at the same time is a sewer surcharge, and that is a different coverage question.
Photograph every discarded item with the date stamp on before it goes to the curb. Contents claims are settled from photos, and a pile at the street is not a photograph of a sofa.

What storm flood cleanup costs

Removal drives the number here, not drying. That is the difference between this and a clean-water loss.

How high it got. Cost scales with the flood cut height, because the cut is priced by the running foot of wall.
How much porous material is in the path. Carpet and pad, drywall, insulation, cabinet boxes, and upholstered contents come out rather than getting dried. That removal is the biggest line.
Whether the water was contaminated, which it almost always is outdoors, adding cleaning and antimicrobial treatment to every surface that stays.
Building age. Pre-1980s texture and joint compound get sampled before demolition, and a positive asbestos result moves that work to a licensed abatement contractor.
Contents volume and where they went. Pack-out, cleaning, and storage are a separate scope from the structure.

Expect a whole-floor flood cut with removal and drying to run into five figures on a typical single-story Houston house, and further once contents and a rebuild are added.

How long a flooded house takes

One to two weeks for the mitigation on a single-story home: demolition and removal first, then cleaning and antimicrobial treatment, then structural drying. Two to four weeks once several rooms, a second story, or a slab-level source is involved. The rebuild that follows is longer than all of it, and after a named storm it is longer still, because every contractor in the region is booked the same week.

Readings decide, not the calendar. Framing, bottom plates and subfloor get metered daily until they hit dry standard, and nothing gets closed up before that. On a Category 3 loss the removal record matters as much as the readings — smell fading is not a clearance test.

What NOT to do

Don’t wade into water near electrical outlets or a submerged panel. Get it de-energized safely first.
Don’t try to save contaminated porous materials. Drying sewage-touched carpet or drywall risks your health; it comes out.
Don’t assume homeowners covers it. Check your flood policy — and if you don’t have one, this is the reason to get one before next season.
Don’t close walls back up wet. In Houston humidity, that’s a mold guarantee.

The free things worth doing tonight

Mark and date the high water line in every room, and photograph it.
Get contents up and out — anything porous that can still be saved, plus documents, photographs, and electronics.
Pull carpet and pad back off the wet edge if you can do it with gloves on. It is the fastest single thing that shortens the dry-out.
Take the baseboards off. They cap the wettest part of the wall.
Run the AC if you have power, not open windows. In Gulf Coast air, opening the house adds moisture rather than removing it — dew point decides that, not temperature.
Find both declarations pages, homeowners and flood, and read what each one covers. They are two different policies with two different adjusters.
Report to both carriers in writing today and keep the confirmations. Flood claims run on their own deadlines.

Before next season, the preparation list is in hurricane season water damage prep.

Where the adjuster and the rebuilder end and we begin

TruePoint Restoration is a mitigation and remediation contractor. We are not a public adjuster and we do not negotiate your claim for you. We do not repair roofs, pipes, HVAC, or electrical systems, and we are not the general contractor who rebuilds your kitchen and re-hangs your drywall. Those are separate trades, and after a named storm they are separate waiting lists — which is exactly why the mitigation should not wait on any of them.

What we do is the part with a clock on it: extraction, removal and bagging of contaminated porous material, flood cuts at the right height rather than a guessed one, cleaning and antimicrobial treatment of what stays, structural drying with logged daily readings, and a documented file — category of loss, water line, affected materials, disposal records, daily readings — that both of your carriers work from and that a buyer’s inspector may ask about years from now.

Call (346) 271-7004. We work out of Pearland and serve Manvel, Friendswood, League City, Pasadena, Sugar Land and the Greater Houston area.

Storm & Hurricane Flooding Questions

What do I do first when my house floods in a storm?

Safety first: don't enter standing water if it's near electrical outlets or the panel — cut power at the breaker only if you can reach it safely and dry, otherwise call the utility. Once it's safe, get people and pets out of the water, document everything with photos and video for your claim, and start removing water and wet contents. Storm floodwater is contaminated, so wear protection and discard porous items that soaked.

Does homeowners insurance cover storm flooding in Houston?

Usually no. Standard homeowners policies exclude flooding from outside — rising water, storm surge, and overflow — which is covered only by a separate flood policy (NFIP or private). Wind-driven rain that enters through a storm-damaged roof may be covered by homeowners. Because the line matters, document the source carefully and check both policies. This surprises many Houston homeowners after a storm.

Is storm floodwater dangerous?

Yes — treat all storm and hurricane floodwater as Category 3 'black water.' It carries sewage, chemicals, bacteria, and debris from the outside environment. Wear boots and gloves, keep cuts covered, don't let children or pets in it, and throw out porous materials it touched (carpet, pad, soaked drywall, upholstered furniture) because they can't be disinfected. This is different from a clean-water pipe leak.

What part of Houston floods the most?

Houston's flooding is driven by its flat terrain, clay soil that sheds water, and a network of bayous that can overflow in heavy rain, plus reservoir-release areas. Neighborhoods near bayous and in historically low-lying areas flood most often, but extreme rain events like Hurricane Harvey put water in areas that had never flooded before. Being outside a mapped flood zone is not a guarantee.

How do you dry out a house after a flood?

Remove standing water, then remove all contaminated porous materials — flood-cut wet drywall above the water line, pull carpet and pad, take out wet insulation. Clean and disinfect the structure, then run commercial dehumidifiers and air movers until framing and subfloor read dry on a meter. In Houston humidity this takes days and can't be rushed, and closing walls back up before it's dry invites mold.

Do I need to remove drywall after flooding?

Almost always, yes — after a flood, drywall that got wet is usually removed by flood-cutting a straight line above the water mark. Floodwater is contaminated, drywall's paper feeds mold fast, and you can't disinfect the inside of a wall cavity. Firm drywall wet only by clean water from a pipe is a different case, but storm floodwater is treated as contaminated and removed.

Will my homeowners insurance pay for flood damage from a storm?

No. Standard homeowners policies exclude flooding from outside — rising water, storm surge, bayou overflow. You need a separate flood policy (NFIP or private). Wind-driven rain through a storm-damaged roof may be covered under homeowners. Check both policies and document the water's source. Houston floods reach homes outside mapped zones regularly.

What does flood insurance actually cover in Texas?

Flood insurance covers water damage from rising water, heavy rain runoff, and storm surge — the actual flooding event. It covers structure, contents, and cleanup. It does NOT cover wind damage, mold from neglect, or sewer backup (separate rider needed). Coverage limits vary. Review your policy limits now; after a storm, it's too late.

How fast can I get flood insurance before a storm?

Not fast enough once a storm is in the Gulf. A new National Flood Insurance Program policy normally carries a 30-day waiting period before it takes effect, with narrow exceptions such as a policy bought in connection with a mortgage closing. Coverage also caps out — NFIP residential building coverage tops at $250,000 and contents at $100,000, and contents is a separate purchase people routinely skip. If you want cover for this hurricane season, buy it in the spring, not in June.

Does FEMA pay for flood damage if I did not have flood insurance?

Not the way people hope. FEMA Individual Assistance, where a federal disaster has been declared for your county, provides limited grants aimed at making a home safe and habitable — it is not a rebuild, and the typical award is a small fraction of what a flooded house actually costs to restore. The larger federal option is an SBA disaster loan, which is money you pay back. Register anyway if a declaration covers your area, and keep every receipt and photo, but do not plan a recovery around it.

What should I photograph before I start throwing things out?

Everything, twice. Photograph and video every room with the water still in it if you can do that safely, then again after it drops and before anything moves — including a shot with a tape measure against the wall showing how high the water sat, in every room. Photograph the pile before it goes to the curb, and cut and bag a small sample of carpet, pad and flooring so the grade and quality can be verified later. Adjusters price from evidence, and discarded items with no photo tend to become discarded claims.

What is the 50 percent rule, and could it force me to raise the house?

It is the substantial damage rule, and around Houston it catches people off guard. If your home sits in a mapped floodplain and the cost to repair it reaches 50 percent or more of the structure's pre-damage market value, your local floodplain administrator — the City of Houston, the City of Pearland, or the county, depending where you are — can require the home to be brought up to current flood elevation standards before repairs are permitted. That decision rides along with the permit, so find out where you stand before committing to a repair scope. NFIP policies include Increased Cost of Compliance coverage that exists to help pay for exactly this.

Is it safe to turn the power back on after flooding?

Not until an electrician has been through it, and this is a fire question as much as a shock question. Panels, breakers, outlets and switches that were submerged get replaced, not dried — floodwater leaves salts and grit inside them that cause arcing and heating long after the surface looks fine. The same goes for any appliance with a motor or a control board that went under. Have the utility or an electrician clear the service before anything is re-energized, and expect the condenser and the air handler to be assessed separately.

The water is gone but I cannot get back in for days — what is happening in there?

Mold is starting. Materials soaked with contaminated water in a closed, unpowered Houston house begin growing within 24 to 48 hours, and after that the question stops being what can be dried and becomes what has to come out. When you do get in, the order is: photograph, then remove the wet material — carpet and pad, soaked drywall flood-cut above the water line, wet insulation, saturated cabinet bases — then clean, then dry with equipment. A house that sat wet for a week is a tear-out job, and treating it as one from the start saves both time and money.
