Pressure and power washing

Clean Sidewalks+ are experienced professionals. We take every cleaning job seriously and will ensure we understand the location and condition of your surfaces before recommending the right approach. Depending on the job we will use different tools and processes to achieve the highest quality of results.
Pressure washing (non-heated) This is the application, by a special nozzle, of highly pressurized water up to 5000 PSI (pounds per square inch). The water is non-heated, but still does an excellent job at removing dirt and other materials from surfaces. The fact that the water is not heated makes pressure washing ideal for non-greasy stains, or more delicate/porous surfaces such as:
Power washing (heated) Like pressure washing, power washing is the application of highly pressurized water. The water is heated up to 250F which makes it particularly effective against tough greasy stains, or stuck on materials like chewing gum. The heated water dislodges dirt faster so it's ideal for large areas like commercial spaces or driveways. The combination of force and hot water, while great for tough stains, can be damaging on delicate/porous surfaces so careful assessment of the surface’s condition is a must. Ideal surfaces for power washing are:
Tool selection Pressure and power washing is more complex than you might think! As with the choice of water temperature, the nature of the stains and surfaces will require different kinds of accessories, ranging from nozzles to surface scrubbers. For example, there are five main types of nozzles, each designed for a specific job:
Cleaning agents Cleaning agents can be introduced to the water flow for both pressure and power washers. There are cleaners to remove dirt, sanitizers to kill most bacteria, and disinfectants that kill all organisms. Where possible, we prefer to use biodegradable cleaning agents. The application of cleaning agents is usually not necessary to achieve high quality results, but can be used for the following:
As an important note: when dealing with excessive amounts of oils or other hazardous materials, extra measures will be taken to comply with state and federal environmental protection laws. |
