The short answer
Stop the Water First
Before you start removing water, find where it is coming from. Check for a burst pipe, a leaky water heater, or heavy rain seeping through the foundation. If you can turn off the water supply or patch a small leak, do that first. This prevents more water from entering while you work.
If the water comes from outside, you may need to wait until the ground dries or divert runoff away from the crawl space. Keep safety in mind: if water is deep or the power is on, do not wade in. Turn off electricity to the crawl space before entering, and wear rubber boots and gloves.
Remove Standing Water
For shallow water, a wet-dry vacuum works well. Move it slowly across the floor to pick up as much as possible. For deeper water, a submersible pump can move water out faster. You can rent one from a local tool store, or you can call the pros to handle it.
If the crawl space has a dirt floor, water may have soaked in. You can still vacuum or pump out the puddles, but the soil will stay damp. In that case, you need to dry the air and the surface over time. Use fans to circulate air and a dehumidifier to pull moisture out.
Wear rubber boots and gloves for protection.
Turn off power to the crawl space before entering.
Use a wet-dry vacuum for shallow water.
Rent a submersible pump for deep water.
Remove any soaked items like boxes or insulation.
If water is contaminated (from sewage or chemicals), call the pros.
Dry the Crawl Space
After you remove the standing water, drying is the key step. Set up fans to blow air across the space, and run a dehumidifier to pull moisture from the air. Keep windows or vents open if you can, but only if the outside air is drier than the inside air.
Drying can take several days, especially in a tight crawl space. Check the floor and walls daily for damp spots. If you see mold starting to grow, act quickly. Mold can spread within a couple of days, so you want to dry the area before that happens.
Use a dehumidifier to lower humidity.
Position fans to create cross-ventilation.
Open vents or windows on dry days.
Check for damp spots daily.
Remove and discard wet insulation.
If mold appears, contact a mold professional.
Know When to Call the Pros
Some water situations are too big for a homeowner to handle alone. If the water is deep, if the crawl space is very tight, or if the water came from a sewer backup, call local water damage pros. They have the right equipment and experience to extract water safely and dry the space properly.
The pros can also help with mold prevention and cleaning after the water is gone. They use industrial fans, dehumidifiers, and sometimes special drying equipment. If you are unsure about the safety of the space, it is better to wait and let the pros handle it. Your health matters more than saving a few hours.

Prevent Future Water Problems
Once the crawl space is dry, think about how to keep water out next time. Check the grading around your home's foundation. The ground should slope away from the house so rain runs off, not toward the crawl space. Clean your gutters and downspouts to prevent overflow near the foundation.
Inspect pipes and water heaters regularly for leaks. Fix small problems before they become big ones. If you live in Layton, keep your shutoff valve location written down so you can act fast in an emergency. A little prevention can save you from another wet crawl space.

How long does it take to dry a crawl space?
Drying a crawl space can take anywhere from a few days to a week or more, depending on the amount of water, the humidity, and the airflow. Using fans and a dehumidifier speeds up the process. If the space stays damp, mold may grow, so check it daily.
Can I use a regular vacuum to pick up water?
No, a regular vacuum is not made for water and can be damaged or cause a shock hazard. Use a wet-dry vacuum, which is designed to handle liquids. For deeper water, a submersible pump is a better choice. Always unplug electric tools before emptying them.
What should I do if I see mold in the crawl space?
If you see mold, do not touch it without protection. Wear a mask and gloves, and avoid stirring up spores. Small patches can be cleaned with a mold cleaner, but large areas need a mold professional. The pros can identify the type and safely remove it.
