Flood Cleanup Equipment You Can Rent

Submersible Water Pumps

Submersible pumps are your first line of defense for removing standing water. These pumps sit directly in the flood water and push it out through a discharge hose to an exterior drain point. They come in various sizes rated by gallons per hour, with larger pumps handling deeper water faster.

For residential flood cleanup, a pump rated at 2,000 to 3,500 gallons per hour handles most situations. These units can clear a typical flooded basement in a few hours rather than days. Larger pumps rated at 5,000 gallons per hour or more are available for severe flooding but require larger discharge hoses and more power.

Rental cost for a submersible pump is typically $40 to $75 per day or $150 to $250 per week. You also need a discharge hose long enough to reach from the pump to an outdoor drain point, usually 25 to 50 feet. Most rental companies include a basic hose with the pump rental, but verify before picking it up. The pump needs a standard 120-volt outlet or a generator to run, and you should use a GFCI-protected circuit or portable GFCI adapter for safety around water.

Commercial Air Movers

Commercial air movers are the workhorses of structural drying. They produce a high-velocity airstream that accelerates evaporation from wet surfaces far more effectively than household fans. A single commercial air mover moves 2,000 to 3,000 cubic feet of air per minute compared to about 500 to 800 CFM from a typical box fan.

You need one air mover per 10 to 16 linear feet of wet wall, plus additional units for open floor areas. A typical room requires 2 to 4 air movers, and a full first-floor flood may need 8 to 12 or more. Position them at angles to create circular airflow patterns and direct air into open wall cavities where moisture hides.

Rental cost for commercial air movers is $25 to $50 per unit per day or $75 to $150 per unit per week. Since you need multiple units running continuously for 3 to 7 days, the weekly rate is almost always more economical. Some rental companies offer multi-unit discounts when you rent 4 or more at once. Each unit draws about 2.5 to 5 amps, so plan your electrical capacity before plugging everything in.

Industrial Dehumidifiers

Commercial dehumidifiers are essential partners to air movers. While air movers evaporate moisture from surfaces into the air, dehumidifiers pull that moisture out of the air and convert it to liquid water for drainage. Without dehumidifiers, the moisture simply recirculates and redeposits on other surfaces.

Commercial dehumidifiers for flood work fall into two categories. Conventional refrigerant dehumidifiers work best in temperatures above 65 degrees Fahrenheit and are the standard choice for most residential situations. They remove 30 to 50 gallons of water from the air per day, compared to 3 to 5 gallons for a household dehumidifier. Low-grain refrigerant (LGR) dehumidifiers are even more efficient and can operate effectively in environments where standard units struggle.

Rental cost for a commercial dehumidifier is $75 to $150 per day or $250 to $500 per week. One commercial unit covers approximately 1,000 to 1,500 square feet of affected area. Set up continuous drainage by connecting the unit's drain port to a hose that runs to a floor drain, sump pit, or exterior discharge. This allows the dehumidifier to run 24 hours a day without manual emptying.

Wet-Dry Vacuums

A heavy-duty wet-dry vacuum is useful for extracting shallow water, cleaning up residual moisture, and handling the general mess that flood cleanup produces. Consumer wet-dry vacuums in the 10 to 16 gallon range work for small areas, but commercial units with larger capacity and more powerful suction handle the volume of a real flood better.

Rental cost for a commercial wet-dry vacuum is $30 to $60 per day. Many homeowners already own a consumer-grade shop vac that can handle basic extraction work, so this may be an optional rental. The primary advantage of a commercial unit is a larger tank that requires less frequent emptying and a more powerful motor that extracts moisture from carpet and padding more effectively.

Moisture Meters

A moisture meter is the only tool that tells you when drying is actually complete. Pin-type meters insert probes into wood and drywall to measure moisture content at the point of contact. Target moisture content for wood framing is below 15 percent, and for drywall below 1 percent. Without objective measurements, you are guessing about whether the structure is dry enough to close up and rebuild.

Professional restoration companies use both pin-type and non-invasive meters, often costing $200 to $500 each. For a DIY flood cleanup, a reliable pin-type meter can be purchased for $30 to $80 and will serve you well for this project and future monitoring. Rental meters are available at $15 to $30 per day from some equipment rental companies, though purchasing is often more practical given the multi-day monitoring requirement.

Where to Rent Flood Cleanup Equipment

National equipment rental companies like United Rentals, Sunbelt Rentals, and Herc Rentals carry the full range of commercial restoration equipment. These companies typically have the best selection of commercial-grade air movers and dehumidifiers, and their staff can help you determine how many units you need based on the square footage and severity of your damage.

Home improvement stores including Home Depot and Lowe's rent equipment through their tool rental departments. Their selection of restoration-specific equipment varies by location, but most carry commercial dehumidifiers, submersible pumps, and wet-dry vacuums. Availability drops sharply after major flood events in the area, so reserve early if your region has been affected by widespread flooding.

Local equipment rental companies are another option, and they often have competitive pricing and flexible rental terms. Some offer delivery and pickup service, which is valuable when you are dealing with a flood emergency and have limited time for equipment logistics. Search for "equipment rental" in your area and call to confirm they carry the specific items you need.

Safety Considerations for Rental Equipment

All electrical equipment used near flood water must be plugged into GFCI-protected outlets or used with a portable GFCI adapter. A ground fault near standing water creates a lethal shock hazard. If the home's electrical system was affected by the flood, have an electrician verify that the circuits you plan to use are safe before plugging in any drying equipment. Using a generator to power equipment requires keeping the generator outdoors and running extension cords inside, as running a generator in an enclosed space produces deadly carbon monoxide.

When operating multiple air movers and dehumidifiers simultaneously, distribute the load across multiple circuits. A single 15-amp residential circuit can typically support two air movers or one commercial dehumidifier, but not both at once. Overloading circuits trips breakers and interrupts the continuous drying that effective restoration requires. Map out which outlets are on which circuits before setting up equipment, and use heavy-duty extension cords rated for the amperage you are drawing.

Estimated Total Equipment Rental Costs

For a typical single-room flood cleanup running equipment for one week, expect to spend $300 to $600 on rentals. This includes one submersible pump for a day or two, 2 to 3 air movers for a week, and one commercial dehumidifier for a week. A full first-floor restoration requiring 8 to 10 air movers, 2 commercial dehumidifiers, and a pump for 7 to 10 days can cost $1,000 to $2,000 in rental fees.

Compare these costs against professional restoration quotes. If a restoration company quotes $5,000 for the drying phase alone, renting the equipment and doing the monitoring yourself saves $3,000 to $4,000, assuming you have the time and ability to manage the process. However, professional companies bring expertise in equipment placement, moisture monitoring, and recognizing hidden problems that DIY operators may miss. The equipment rental cost savings must be weighed against the risk of incomplete drying and its consequences.
