Can a crawl space be dried while it is still damp from the ground?
Yes, provided the source of the water is stopped and the ground cover is read. A crawl space that stays damp from the ground needs ventilation or dehumidification, and sometimes a ground cover that holds less water, and the readings show whether the moisture is falling.
A damp ground that keeps producing moisture is a sign that the water is still coming in. The crew checks the drainage at the perimeter and the vents, and it tells you whether the source is still active.
A ground cover or a drainage change is a separate repair, and it is explained and approved before any work is done in the space.
Should I enter a crawl space that has water in it?
No. A crawl space with standing water can hide electrical hazards, poor air and animals. Do not enter it or switch on equipment down there, and call so that the crew can plan the access.
The crew checks the power and the air before it goes in, and it works from the access point wherever possible.
If the water is coming through the foundation or the slab edge, note where it is seen. That observation helps the crew find the entry route.
Why is the floor above still soft after the crawl space looks dry?
The joists and the subfloor can hold moisture after the surface of the crawl space looks dry. Soft or cool floors above are a sign the framing still holds water, and the crew reads the joists to check it.
A dry surface on the ground cover does not mean the framing is dry. The crew takes readings on the joists, the sill and the subfloor underside, and it records them against the dry goal.
If the floor stays soft after the readings reach the goal, the crew checks for a second source, such as a leak or a rot point, and reports what it finds.
What moves the cost of crawl space or slab work up or down?
The depth of water, the size of the space, the access, the condition of the framing and ground cover, the amount removed and the number of visits all change the cost. No figure is published here, and the price is explained and approved before any work begins.
A shallow, accessible space with dry framing costs less than a deep, tight one with soaked joists. Removing soaked framing and ground cover is part of the price.
Drainage and ventilation changes are separate repairs with separate estimates. Ask for each one in writing, so you can see which part of the total each one covers.
When is the floor above ready to be reset?
The floor is ready when the readings in the framing, the subfloor and the space have reached the dry goal and stayed there across more than one check, and when the source has been stopped. Resetting it earlier can trap moisture and cause staining or a smell later.
The crew's log shows the readings and the dry goal, and it is the record a flooring contractor will want before the floor is reset.
Permits may be needed for structural work on the framing or the foundation. The Bossier Parish and City of Bossier City permit offices answer repair-permit questions for their own jurisdictions, and this page has not checked their requirements.
