The short answer
Start with Extraction and Air Movement
Before any dehumidifier runs, the pros remove standing water with pumps and wet vacuums. They also place air movers, which are high-velocity fans, to create constant airflow across wet floors, walls, and furniture. Moving air speeds up evaporation, so the dehumidifier can pull moisture out of the air more effectively.
- Remove standing water first
- Place air movers to create airflow
- Open cabinets and closets
- Lift carpet edges and padding
- Position fans at wet walls and floors
Choose the Right Dehumidifier Type
Two main types of dehumidifiers are used: refrigerant and desiccant. Refrigerant units work like an air conditioner, cooling coils to condense water from the air. They work well in warm conditions. Desiccant dehumidifiers use a moisture-absorbing material and work better in cooler or tighter spaces, like a crawlspace or a closed room.
The pros select the type based on the temperature, the size of the area, and how wet the materials are. For a large open area, they might use multiple refrigerant units. For a small, cold space, a desiccant unit is often more practical. They also use moisture meters to check the moisture content in wood and drywall.
- Refrigerant for warm, open areas
- Desiccant for cool, tight spaces
- Moisture meters to check wood and drywall
- Multiple units for large spaces
- Adjust type based on temperature
Set Up Drying Zones and Monitor
The pros divide the affected area into drying zones. Each zone gets its own dehumidifier and air mover, so the equipment works efficiently. They monitor humidity levels with hygrometers and adjust the settings as the air dries. The goal is to bring the relative humidity down to around 40 to 50 percent, depending on the season and the home's normal conditions.
They also check the moisture content in materials like wood floors and drywall. If a wall still reads high, they keep the dehumidifier running and move air movers closer. This monitoring continues until the materials reach a safe level, not just the air. That prevents hidden mold and rot from developing later.
- Divide the area into zones
- Use hygrometers to track humidity
- Aim for 40 to 50 percent relative humidity
- Check moisture in wood and drywall
- Adjust equipment based on readings
Handle Drying According to Material
Different materials dry at different speeds. Hardwood floors may warp if dried too fast, so the pros slow down airflow in those areas. Drywall might need to be removed if it is soaked through, because it can sag or grow mold. Carpet and padding can often be dried and cleaned in place, but only if the water was clean and the drying starts quickly.
The pros also watch for signs of hidden moisture, like a musty smell or a soft spot in a wall. If they find wet insulation or a void, they open it up to let air in. This careful approach prevents secondary damage, such as rusted fasteners or peeling paint, which can happen when moisture stays trapped.
- Slow airflow for hardwood floors
- Remove soaked drywall if needed
- Dry carpet and padding if clean
- Open wet wall cavities
- Watch for musty smells
Know When to Seek Professional Help
For a small spill, a home dehumidifier and fans might be enough. But for a large flood, a burst pipe, or a sewage backup, the drying process is complex. The pros have industrial equipment and know how to reach moisture behind walls and under floors. They also know how to avoid electrical hazards and structural issues during drying.
If the water came from a sewage backup or contains contaminants, the drying process changes. The pros treat it as a biohazard, remove affected materials, and disinfect the area before any dehumidifying starts. Policies vary, and your insurer decides what is covered. You should avoid touching the water and see a doctor if you feel unwell. Acting quickly is key, especially after a storm or flood, to limit damage and health risks.
- Large floods need professional equipment
- Sewage backups require special handling
- Electrical hazards are a concern
- Professionals can access hidden moisture
- Act quickly to prevent mold

How long does dehumidifying a home take?
The time depends on the extent of the water damage, the materials affected, and the humidity outside. A small area might dry in a few days, while a whole-house flood can take a week or more. The pros monitor moisture levels to know when the job is done.
Can I use my own dehumidifier instead of calling pros?
For a small, contained leak, your own dehumidifier and fans might work. But if water has soaked into walls, floors, or insulation, you need industrial equipment and proper technique. A home unit may not pull enough moisture fast enough, leading to mold and rot. When in doubt, call local water damage pros.
What if the water was from a sewage backup?
Sewage water is a biohazard and requires special handling. The pros will remove contaminated materials and disinfect the area before any dehumidifying begins. You should avoid touching the water and see a doctor if you feel unwell. Your insurance company may have specific requirements for cleanup.
