How Much Does Structural Drying Equipment Cost to Run?
Last updated October 23, 2026
The short answer
Key Factors That Determine Operating Costs
The primary cost to run drying equipment is your electric bill. Large commercial dehumidifiers and high-volume air movers are powerful tools that consume considerable electricity. The final operating expense hinges directly on the scale of the water damage and the required drying time. More equipment running for more days means a higher total cost on your utility statement.
Your local utility's kilowatt-hour rate is a major variable. Rates vary significantly by region and time of day. The equipment's total wattage, multiplied by the hours of operation and your electricity rate, gives the cost. Local climate, such as high summer heat and humidity, can increase overall power demand and affect your total bill.
Equipment Types and Their Power Draw
Different machines have different energy appetites. A standard air mover might use 600 to 1,200 watts, similar to a space heater. A large refrigerant dehumidifier can draw 500 to 800 watts, while a desiccant dehumidifier, used for very cold or very wet jobs, may consume 1,500 watts or more, comparable to a hair dryer on its highest setting.
- Low-Grain Refrigerant (LGR) Dehumidifiers: Common for residential jobs, moderate power draw.
- Desiccant Dehumidifiers: High power use, reserved for extreme humidity or low temperatures.
- Axial Air Movers: Lower wattage, used for general airflow across surfaces.
- Centrifugal Air Movers: Higher wattage, create focused, high-velocity air for tight spaces.
- Air Scrubbers: Use fans and filters, power draw similar to an air mover.
- Heating Systems: Optional for cold areas, add significant wattage if used.
Estimating Your Potential Electricity Cost
You can get a rough estimate by understanding the equipment's wattage. First, ask the pros for the total estimated wattage of all equipment they will use. Convert watts to kilowatts by dividing by 1,000. Then, multiply kilowatts by your local electricity rate and the estimated number of hours the gear will run to see a potential daily cost range.
For example, 5,000 watts of equipment is 5 kilowatts. If your power costs 15 cents per kWh and it runs for 24 hours, the daily cost is about eighteen dollars. A more severe loss requiring 10,000 watts could cost around thirty-six dollars daily. Remember, these are simplified examples, and actual runtime depends on moisture readings taken by the pros.
Why Professional Drying Is Still Cost-Effective
While the electricity cost is real, proper structural drying prevents far more expensive problems. Incomplete drying leads to hidden moisture, which can cause severe mold growth and wood rot. The repair cost for replacing structural framing, subfloors, and drywall due to mold or decay is vastly higher than a few days of equipment runtime. Effective drying protects your home's long-term value and safety.
The pros use moisture meters and sensors to dry your home systematically and efficiently. This scientific approach ensures they use equipment only as long as absolutely necessary, avoiding wasted energy and time. Their goal is to restore a dry standard quickly, which ultimately minimizes both the operational costs and the risk of secondary damage that drives up the total restoration bill.
Managing Costs and Insurance Considerations
Discuss the drying plan and estimated timeline with the water damage pros upfront. They can explain why specific equipment is necessary for your situation. If you are concerned about electricity costs, ask if there are ways to improve home efficiency during drying, like keeping exterior doors closed to contain conditioned air. Your actions can support the process and potentially reduce runtime.
If you file an insurance claim, the operating cost for necessary drying equipment is typically a covered part of the mitigation expense. You should keep copies of your utility bills showing increased usage during the loss period. Policies vary, and your insurer decides what is covered. Submit these documents with your claim for review, as they help document the legitimate cost of preventing further damage.
- Request an equipment list and estimated runtime from the pros.
- Keep exterior doors and windows closed to maintain drying efficiency.
- Save utility bills from the drying period and the same period last year.
- Provide moisture log documentation from the pros to your insurance adjuster.
- Understand that electricity for temporary equipment is different from your normal usage.
- Ask your adjuster what documentation they require for equipment power costs.

Is the electricity cost for drying equipment covered by insurance?
Often, yes. The power to run necessary drying equipment is generally considered a legitimate mitigation expense. You must document the extra usage, usually by providing utility bills. Policies vary, and your insurer decides what is covered.
How long does structural drying equipment usually need to run?
Drying typically takes two to five days, but severe flooding or saturated building materials can take a week or more. The pros use moisture meters daily to track progress. They remove equipment as soon as each area reaches a dry standard.
Can I just rent the equipment and run it myself to save money?
This is not advised. Incorrect placement or use can waste energy and fail to dry hidden cavities, leading to mold. Water damage pros use a scientific process with meters to ensure effective, efficient drying that truly protects your home.
