Frequently Asked Questions

We all have backgrounds in heavy industry and construction, so we offer services that most don’t. We also build all our equipment in house to heavy industry specifications and versatility. Sewer line jetting, steam cleaning, tank cleaning and commercial roof cleaning are areas where we thrive. Our backgrounds also ensure that we are extremely safety conscious and have decades of training.

Pressure washing utilizes flows of water between 1500 pounds per square inch (PSI) and 3500 PSI. Soft washing typically runs at less than 500 PSI with cleaning agents injected into the stream. Pressure washing is used for hard surfaces (concrete, brick, steel, etc.), while soft washing is utilized on siding, roofs and other more delicate surfaces.

Yeah, but the part you started on will be dirty again by the time you’re finished! So, in reality, NO.
PSI is secondary when it comes to cleaning power. Gallons-per-minute (GPM) is king. Think of it this way … a garden hose and a fire hose aren’t that far apart in PSI. The fire hose is just putting out about 20 times the GPM as the garden hose.
Most Big Box pressure washers put out between 3 and 4 GPM. Commercial washers start out at 4.5-5 GPM. Our rigs feature 16+ GPM.
A homeowner pressure washer is OK for cleaning very small areas. Once you start cleaning your driveway with one of those, you’ll understand. It takes forever, and the final product is not good.

We run variable-pressure, flexible lines through your cleanout to flush your line clean to the nearest manhole (usually less than 50 feet). We like to do this twice a year to keep everything flowing.
The benefit is somewhat hidden. You don’t realize how important it is until you have to call a plumber.

Our rigs are equipped with industrial boilers that heat the water up to a maximum of 250 degrees Fahrenheit. We adjust that temperature for each situation; usually 140 degree water (about what your dishwasher uses) is adequate for most surfaces.
But when you’ve got 10 GPM, 3000 PSI, 250 degree water pointed at something, it’s probably going to lose!

Some chemicals will damage - or kill - delicate vegetation. We consult with property owners/managers prior to work and take the necessary precautions.
In our experience, areas where heavy chemical is required usually don’t have sensitive plants. It does happen; just not very often. That’s why job planning is crucial.
Typically a wetting-down of the vegetation prior to and after washing a building is more than enough. If the vegetation is particularly delicate, it will be covered with a breathable tarp during the process.
