Pressure washing, also known as power washing, is a versatile cleaning technique that utilizes high-pressure water to remove dirt, grime, and other unwanted materials from various surfaces. This specialized service falls under the category of “Other Services to Buildings and Dwellings” as defined by the North American Industry Classification System (NAICS) code 561790.
Understanding the NAICS Code 561790
The NAICS code 561790 encompasses a wide range of services related to the maintenance and upkeep of buildings and dwellings. This category includes, but is not limited to, the following services:
-
Exterior Building Cleaning: Pressure washing is a popular method for cleaning the exterior of buildings, including walls, siding, and roofs, to remove accumulated dirt, mildew, and other contaminants.

Pressure Washing Equipment and Techniques
Pressure washing equipment typically consists of a high-pressure water pump, a wand or lance, and various nozzles and attachments. The water pressure generated by these machines can range from 1,000 to 4,000 pounds per square inch (PSI), with flow rates ranging from 1 to 4 gallons per minute (GPM).
The specific equipment and techniques used in pressure washing will depend on the surface being cleaned, the level of soiling, and the desired outcome. For example, softer surfaces, such as wood or vinyl, may require lower pressure settings to avoid damage, while harder surfaces, such as concrete or brick, may require higher pressure settings to effectively remove stubborn dirt and grime.
Pressure Washing Safety Considerations
Pressure washing can be a powerful and effective cleaning method, but it also carries inherent risks that must be addressed. Proper safety precautions are essential to prevent injury and ensure the safe and effective use of pressure washing equipment.
Some key safety considerations include:
-
Personal Protective Equipment (PPE): Pressure washing operators should wear appropriate PPE, such as safety goggles, gloves, and slip-resistant footwear, to protect themselves from the high-pressure water and any debris that may be dislodged during the cleaning process.
-
Electrical Safety: Pressure washing equipment often involves the use of electrical components, such as pumps and motors. Proper grounding and the use of ground-fault circuit interrupters (GFCIs) are essential to prevent the risk of electric shock.
-
Slip and Fall Hazards: The water used in pressure washing can create slippery conditions, increasing the risk of falls. Operators should take precautions to ensure the work area is free of obstacles and that proper signage is in place to warn others of the potential hazard.
-
Noise Exposure: Pressure washing equipment can generate high levels of noise, which can pose a risk to the operator’s hearing. The use of appropriate hearing protection, such as earplugs or earmuffs, is recommended.
-
Chemical Exposure: Some pressure washing applications may involve the use of cleaning agents or chemicals, which can pose health and environmental risks if not handled properly. Operators should follow the manufacturer’s instructions and use appropriate PPE to minimize exposure.
-
Damage to Surfaces: Improper use of pressure washing equipment can damage delicate surfaces, such as wood, paint, or soft materials. Operators should carefully select the appropriate nozzle, pressure, and technique to avoid causing unintended damage.
Pressure Washing Regulations and Certifications
The pressure washing industry is subject to various regulations and certifications that ensure the safety and quality of the services provided. Some of the key regulatory bodies and certifications include:
-
Occupational Safety and Health Administration (OSHA): OSHA sets standards and regulations for workplace safety, including the use of pressure washing equipment.
-
Environmental Protection Agency (EPA): The EPA regulates the use and disposal of chemicals and wastewater generated during pressure washing activities to minimize environmental impact.
-
Pressure Washing Resource Association (PWRA): The PWRA is a professional organization that provides training, certification, and industry standards for pressure washing professionals.
-
Certified Pressure Washing Technician (CPWT): The CPWT certification is a recognized credential that demonstrates an individual’s knowledge and expertise in the safe and effective use of pressure washing equipment and techniques.
-
