Why does a crawl space in Kenner flood when the house does not?
A crawl space is the lowest part of the house and is open to the ground. Water can enter through vents, foundation gaps and the soil itself, and it can collect there even when the living space stays dry. The crawl space therefore floods first in many heavy rains, and the living space above may be spared.
The vents that let air into a crawl space also let water in when the yard is flooded. A vent set low in the foundation is at the same height as the standing water. Gaps where a pipe or a cable enters the crawl space can admit water in the same way, and so can a crawl space access door that does not seal.
The ground itself can also be the source. When the soil is saturated, water can move through it into the space under the house, even without a visible flood on the surface. That is why a crew checks the ground under the house as well as the vents and the access point.
How does a crew dry a crawl space without damaging the framing?
The crew removes standing water, reads the framing, and then moves air through the space with equipment placed to reach the joists and subfloor. It avoids sealing the space while it is wet and does not use heat that could dry the wood too quickly. The drying is checked against the same readings on each visit.
Wood that dries too fast can split, twist or shrink, so the crew aims for a steady drying rate. Air movers are set to move air across the joists without blasting one spot. Dehumidifiers pull moisture from the air in the space, and they run until the readings show the framing is recovering.
The crew checks the vents and the access point for air movement, because a space that cannot breathe holds moisture. Where vents are blocked or damaged, the crew notes it for the homeowner to address.
Should the floor above be repaired before the crawl space is dried?
No. The floor above should not be repaired until the crawl space and the subfloor are confirmed dry, because a new floor laid over a wet subfloor can trap moisture and hide the damage. The crew confirms the readings first, and the floor repair follows.
Repairs that come too early can cause problems later. A new floor covering or insulation installed over damp framing will hold moisture against the wood. A homeowner who wants the floor fixed should ask the crew when the readings will allow it, and the crew can say which materials are ready.
Where the subfloor is soft or rotted, the crew notes it, and the repair is planned once the readings are dry enough for the wood to be assessed properly. That assessment is part of the job record.
What affects the time and cost of crawl space water removal?
The depth of the water, how long it stood, how much framing and insulation is wet, and how easily the crew can reach the space all matter. The presence of debris and the condition of the vents also change the work. Each job is priced after the walkthrough, and no price is quoted over the phone.
A crawl space with a low ceiling takes longer to work in, because the crew cannot stand up and must move equipment on its knees. Debris that has washed in must be cleared before the readings can be taken. These factors add to the hours, and they are explained before the work begins.
The size of the house and the number of joists affected also matter. A small space with one wet corner is a different job from a space that is wet from end to end. The crew confirms the scope in writing before it sets equipment.
What should a homeowner do before the crew arrives?
Keep away from the access point if there is standing water near it, and do not enter the crawl space. Switch off power only at a dry panel, and tell the phone team whether you can smell damp air or hear water under the house. Photograph any staining you can see from the room above.
Do not crawl into standing water to look, and do not use a flashlight near water if you cannot see the outlets and lines clearly. The crew checks the space from the access point and enters only when it is safe.
If the floor above feels soft, keep heavy furniture off that area until the crew has checked it. Write down when the damp smell or the soft spot was first noticed, because that time is part of the record.
