Flood Water Cleanup In Harvey, LA

Signs Of Hidden Water Damage After A Flood

Musty smells, swelling baseboards, bubbling paint and soft-feeling floors point to moisture still inside the structure after visible water has gone. If signs are appearing now, the Harvey emergency flood page explains what to do first.

What Causes Flooding In Harvey Homes?

Homes here flood when heavy rain overwhelms parish drainage, when waterways rise against low ground, when storm water presses in from outside, and when plumbing fails. Ground floors and garages take water first, and it spreads under flooring before being noticed.

Which Types Of Flooding Affect Harvey?

Harvey faces the full Gulf set: coastal flooding and storm surge effects, riverine flooding from rising waterways, flash flooding in intense rain, and drainage flooding when systems back up. Sitting at -3.5 feet of elevation, it has no gravity drainage to fall back on when those systems are full.

The 3 Water Categories, And Why Floodwater Is Category 3

Water is graded from Category 1 (clean) to Category 3 (grossly contaminated). Floodwater is always Category 3: it crossed streets, yards and drains, picking up bacteria, chemicals and sometimes sewage. That grading decides the sanitizing and material removal a Harvey home needs.

What Floodwater Carries Into A Home

Floodwater carries whatever it crossed: road oil, chemicals, fertiliser, bacteria and, where drains surcharge, sewage. That is why soaked porous materials cannot simply be dried and kept, and why framing gets an antimicrobial treatment once extraction is finished and surfaces are clean.

How Pros Find Hidden Flood Water

Pros use moisture mapping: systematic moisture meter readings across floors and walls, recorded room by room. The map shows how far water travelled, plans the drying equipment, and later proves in a drying log when the structure has genuinely reached dry targets.

How Thermal Imaging Finds Moisture In Walls

A thermal imaging camera shows temperature differences on a surface, and damp areas read cooler as water evaporates. Pros scan first, then confirm each suspect area with a meter reading before deciding whether the wall needs opening or can dry in place.

Where Flood Water Hides In A House

Flood water hides in wall cavities, under laminate and vinyl plank flooring, inside insulation and beneath cabinets. Baseboards swell because the cavity behind them is wet. Finding these pockets is what separates a Harvey home that dries from one growing mold behind its walls.

What Happens First When A Pro Arrives?

First comes a safety assessment: power and water risks, contamination level, and whether each room is safe to enter. Only then does extraction begin, after the pro has explained the findings, the recommended sequence and what the first visit will cover.

How Standing Flood Water Is Removed

Crews use submersible pumps for depth, then truck-mounted extraction units and wands that pull water from carpet and hard floors. Every gallon removed mechanically is one the drying equipment does not have to evaporate over the following days of monitored drying.

How Mud, Silt And Debris Are Cleaned Out

Silt and mud are shovelled and washed from hard floors before they dry into contaminated dust; debris is bagged and removed. Around Harvey the silt is river and street sediment mixed with whatever the water crossed, and it is handled as contaminated either way.

Why Crews Cut Drywall After A Flood

A flood cut removes drywall just above the water line, because wet drywall and the insulation behind it rarely dry safely after Category 3 exposure. Opening the wall lets the framing dry and be treated, and it simplifies the later repair stage.

How A Home Is Sanitized After Flooding

After contaminated materials come out, framing and hard surfaces are cleaned and given an antimicrobial treatment. Odor removal follows the same logic: source material goes, surfaces are treated, and HEPA air scrubbers filter the air while drying equipment runs.

How Structural Drying Works

Air movers push air across wet surfaces, a dehumidifier pulls moisture from the air, and readings are logged daily against safe targets for framing, subfloor and cavities. Our guide to what water remediation involves explains where drying fits.

What Happens To Furniture And Belongings?

Contents are judged item by item: hard items can often be cleaned; soaked mattresses, carpet pad and soft furnishings usually cannot be made safe. A contents packout inventories and moves saveable belongings out of the work area so rooms can be dried.

What Repairs Happen After Cleanup And Drying?

Repairs begin only after moisture readings pass: new drywall and insulation, refitted baseboards, repaired flooring and cabinetry, redecorating. Repairs sealed over damp framing fail early, so the drying log is the document that clears this stage to start.

How Long Cleanup And Drying Take, Phase By Phase

Extraction usually takes hours, material removal a day or so, structural drying several days of monitored equipment, then repairs. Water depth, materials and how quickly work started move every phase, and your pro will phase the timetable honestly.

Documenting Flood Damage For An Insurance Claim

Photograph every room before cleanup, keep the moisture map, drying log and all receipts. Louisiana's claim rules sit on the Flood Water Cleanup Louisiana page. Documentation is the strongest thing a homeowner controls in a claim.

What Can Be Saved, And What Must Be Removed?

Tile, concrete, solid wood and metal often survive cleaning; drywall, insulation, carpet pad and particleboard cabinetry usually do not. Food, medicine and cosmetics touched by floodwater are always discarded. The pro marks each material on site, room by room.

Drywall, Insulation And Flooring, Material By Material

Drywall wicks water above the visible line and is cut out; insulation holds contaminated water and comes out too; hardwood can cup; laminate and vinyl plank trap water against the subfloor; carpet pad is always removed, carpet judged case by case.

What Makes Harvey Flood-Prone?

Elevation, or the lack of it: a community at -3.5 feet taking 68.6 inches of parish rain a year, with coastal and riverine risk both scored above 95. FEMA flood zone maps show which streets carry mapped risk. The Gretna, LA flood water cleanup page shows a neighbouring Westbank profile.

What The Sourced Local Numbers Say

Jefferson Parish averages 68.6 inches of rain a year (NOAA, 2015–2024); FEMA scores parish hurricane risk at 98.97, coastal flooding at 96.18 and riverine flooding at 95.48 (NRI, March 2023); 61.8% of city homes predate 1980 (ACS 2024). Flood cleanup here is a when, not an if.

Garages, Ground Floors And First Floors After Flooding

Garages and ground floors take water first and hold silt and stored-item losses. Cleanup extracts water, removes contaminated stored materials, washes hard surfaces and dries slab and walls. Our mold prevention guide protects the rooms above.
