Gretna sits at about -1.3 feet, so water that gets indoors tonight will not simply drain away. Ring (800) 555-0100 straight away: the call is free, the line is staffed around the clock, and a nearby independent pro can usually reach homes in 70053 and 70056 within 30 to 60 minutes.
Free Call Answered 24/7 Local Pros Near You
Three simple steps, and the call itself is free.
Dial (800) 555-0100 the moment flooding becomes an emergency, whatever the hour. Name the rooms affected and say whether levels are climbing; that detail grades your call as urgent from the outset.
Your call passes directly to an independent pro who covers Gretna. You describe the property once, agree what equipment is needed, and the pro sets out with pumps matched to the depth you reported.
Expect either an immediate callback or a visit straight away. Either way the pro confirms entry is safe, checks electrical and contamination risks, then begins removing water while explaining what will happen during that first attendance.
The emergency services a local pro provides here.
Think of restoration after a Gretna flood as a sequence rather than a single visit. A pro first checks for hazards, removes standing water, then maps damp walls and floors before rebuilding is discussed. Because 73.1% of homes here predate 1980, hidden cavities often need early attention. Calling tonight starts that sequence while damage is confined to fewer rooms.
📞 Call NowMold can follow a Gretna flood quickly once warm, damp plaster and timber sit shut away. Mention on your first call if a musty smell is developing, or dark patches have appeared. A pro can then plan containment, removal of unsound material and antimicrobial treatment into the visit, instead of treating growth as an afterthought.
📞 Call NowSome repairs cannot wait for full drying: a saturated ceiling section, flooring that no longer feels solid, or storm openings that leave a room exposed. In Gretna those urgent jobs sit apart from later cosmetic work. A pro will stabilize whatever threatens safety tonight, record moisture readings, and postpone rebuilding until walls and subfloors have dried properly.
📞 Call NowStreet water entering a Gretna home is never just rainwater. Along the road it can collect fuel traces, grit, sewage and garden chemicals before crossing a threshold. The response therefore pairs fast pumping with clearing silt, discarding porous items that cannot be cleaned, washing hard surfaces and sanitizing treatment. Acting early limits how far contamination spreads through ground-floor rooms.
📞 Call NowCleanup in emergency terms means leaving a home safe enough for its occupants — not finished, but cleared. Crews in Gretna remove pooled water, carry out saturated carpet and debris, then wash hard surfaces room by room. Cover runs through both 70053 and 70056 at all hours, so that first stage can begin tonight rather than waiting for a weekday appointment.
📞 Call NowRemoving the water itself comes before every other decision. Pros use submersible pumps where depth allows and extraction units where spread is shallower, working outward from the lowest points. In a city below sea level, gravity does almost none of this work. Early extraction reduces wicking up walls, protects flooring and shortens the drying stage that follows.

Start by getting household members and pets onto dry flooring, then ring (800) 555-0100 without waiting to see whether levels drop. At Gretna's elevation of about -1.3 feet, pooled water has no downhill route out. A nearby pro can usually attend within 30 to 60 minutes. While travelling time passes, photograph conditions from a doorway and touch nothing electrical that water may have reached.
No, regard it as unsafe even where it looks shallow. In Gretna that water will have crossed streets first, picking up bacteria, grit and chemical traces, and it hides the condition of the floor beneath. Where it meets a socket, cord or appliance, electricity becomes the immediate worry. Keep out, keep children and pets out, and leave entry to a pro wearing protective equipment.
Only under strict conditions: dry hands, dry footing, and a route to the panel crossing no wet surface whatsoever. If any of those fails, abandon the attempt, keep the household away from switches and appliances, and explain the position on your call to (800) 555-0100. A panel that has itself flooded will need a qualified electrician once extraction and drying are complete.
In ordinary conditions, yes. The line at (800) 555-0100 is answered at all hours, and pros covering 70053 and 70056 plan on reaching Gretna within 30 to 60 minutes. Severe Jefferson Parish weather can stretch any journey, which is why calling during the storm beats calling after it: your address joins the queue earlier, while the water is still smaller.
Report the smell in plain terms and add any detail you have — which drain or toilet bubbled, and in which room. That pattern suggests surcharge mixing with flood water already handled as the most contaminated category. Keep skin contact at nil, keep children and animals in a separate dry area, and do not start scrubbing floors yourself. The pro will adjust protective equipment and antimicrobial treatment accordingly.
Collect what dry hands on dry floors can reach: identification, insurance papers, medication, chargers and small valuables are the priorities in Gretna. Nothing reached by wading qualifies, however important it feels. A vehicle should leave a garage only where the garage floor is dry around electrical fittings and the way out is clear. Doorway photographs are worth more tonight than belongings rescued at personal risk.
Settle them in the driest unaffected room and keep it that way — a closed door helps, because children return for toys and animals will lap at unfamiliar water. In Old Gretna and McDonoghville, where homes sit close together, a trusted neighbor may offer a dry refuge; if you leave, tell the pro where you have gone and keep your phone audible. Do not allow re-entry until the pro clears a room.
Act as though minutes matter, because they do. Clear the room, touch no switches or plugs, and state the detail early in your call to (800) 555-0100. Gretna's housing sharpens the concern: a median build year of 1966 means many panels and sockets have decades behind them. Afterwards, any appliance that sat in water should stay unused until examined.
Pumping is normally the centrepiece of that first attendance, once hazards have been checked. In Gretna there is rarely a drainage alternative, given the city sits slightly below sea level. Expect extraction from the deepest rooms first, removal of material too saturated to retain, and drying equipment left running. You will also be told what tomorrow's visit covers.
Get to the highest dry area inside, or leave for a safer nearby address if you can do so without crossing deep or fast-moving water. Where anyone faces immediate danger, 911 comes before any cleanup number, always. Otherwise remain in contact with (800) 555-0100, report that levels are still climbing, and update the pro as conditions change — that information alters access, equipment and urgency on the way to you.
Act in this order in Gretna, LA. First, move people and animals into rooms that remain dry. Next, avoid any pooled water that has reached plugs or appliances. Collect only belongings you can reach without stepping into it. Then ring (800) 555-0100; a nearby pro typically reaches the city within 30 to 60 minutes, around the clock. After tonight is under control, the ordinary Flood Water Cleanup Gretna, LA page explains the longer recovery in full.

Safe steps only — do these while you wait for the pro.
The danger in a Gretna flood is not measured by depth alone. Water at ankle height can still conceal a live cord, a shifted board or contamination picked up outdoors. It spreads bacteria across skin and into small cuts, and leaves softened material underfoot. Gretna adds a particular problem: at roughly -1.3 feet, homes sit below sea level, so entered water tends to stay put instead of easing toward a drain. Waiting for it to recede can mean watching damage advance for hours. Regard each affected room as out of bounds until checked. Keep household members on dry flooring, resist rescue trips for possessions, and place the call early.
Well done — you have done the safe first steps. Now let a pro handle the water.

What to do while you wait, and what the pro does first.
Fill the wait with small, dry-footed jobs only. Remain in the unaffected part of the house together, pets included. If the floor beneath you is dry, put medicines, chargers and essential papers into one bag by the door. Photograph each flooded room from outside its doorway. Leave mopping alone, keep fans out of wet rooms, and do not haul at soaked carpet: lifting it the wrong way spreads contaminated water across clean floors.
Picture the common Gretna pattern: rain continues, the street fills, and water slips over the threshold faster than a household can bail it. Do not lean a door shut against pressure building outside, and do not attempt improvised barriers from within a flooding room. Shift anything you can reach without wet feet onto raised furniture, make your call, and allow extraction to begin as the inflow eases.
Once water touches a socket, a water heater, a washer or the HVAC system, treat the situation as electrical first and wet second. Nobody should step into that area, touch switches, or handle a panel with damp hands. Shutting power off is sensible only from a completely dry position; where any doubt exists, leave the supply alone and describe the problem when you call.
Bubbling toilets, drains that push back and a distinct sewage odor point to surcharge adding to the flood inside. Flood water is handled as Category 3 regardless, so keep bare skin away entirely. Open a window from a dry side if possible without crossing water. Tell the pro which fixtures behaved oddly and where the smell is strongest; that shapes protective kit, containment and sanitizing.
Plaster overhead that bows downward is carrying weight, and it can give way suddenly rather than gradually. Keep the whole household out of that room, however valuable the contents look from the doorway. Do not duck underneath for a pet carrier or a photograph. If the door can be closed from a safe position, close it, pass the detail on during your call, and leave controlled draining to the pro.
Begin with people: household members and pets onto dry ground. Follow with distance from anything electrical that water may have reached. Third, raise documents and valuables, only along routes involving no wading. Fourth, record conditions in photographs taken from dry positions. Finally, call (800) 555-0100 with three facts ready — your ZIP code, which rooms are affected, and whether the level is rising, steady or falling.
Arrival starts with safe entry: the pro looks for electrical danger, contamination and any route by which water is still getting in. Work then moves to the deepest area, where pumps remove the bulk, before shifting outward to shallower rooms. Alongside that, moisture readings trace how far damp has travelled into walls and under flooring. By the end of the hour you should have a spoken summary — what came out, which materials cannot stay, and what drying is running.

Unsure whether what you are seeing in Gretna qualifies tonight? Select any description that fits: indoor water that refuses to fall, damp reaching sockets, drains pushing back or smelling of sewage, plaster overhead starting to bow, or levels creeping upward while you watch. Any one of these can signal a flood emergency — contact a local pro for an assessment. Only an inspection on site can confirm the true scale, and asking early will always cost less than asking late.
