Pressure washer and power washing are usually confused with each other. Both use a high-pressure stream of water. However, the difference between the two types of washing is the use of heat in the case of power washing. Either of these types can clean off certain types of surfaces. Especially in New England’s climate, the end of the winter season would yield surfaces in your property where you will find assorted kinds of dirt, grime, deep-seated dust and dirt, old paint, and even chewing gum. However, power and pressure washer are options for surface preparation before the painting job. In that case, there may be other considerations to the type of surface to be subjected to intense water pressures. But before you set off and begin using power or pressure washer nozzles to clean your driveways, patios, or vinyl siding, there are five things you need to know before you can achieve roof cleaning, patio cleaning, etc these surfaces safely and effectively.
For instance, if these are tough stain wood painted over, best power washing may not be an issue at all. For these considerations, you need the support of cleaning and painting professionals to ensure a perfect job for the appropriate applications.
What Surfaces Should Not Be Subjected to Either Pressure or Power Wash?
First of all, please take note of the materials making up the surface you want to wash. Certain material types will be damaged if subjected to a high-pressure water jet. It is best to consult a professional before the cleaning process on any of these surfaces. In the case of asphalt roofing, you should not try it.
- Anything painted: If you don’t want to wash off the paint on the surface you are gutter and roof cleaning, you must call on a professional to do this job for you. But if you insist, please expect the paint to peel off, especially if you use power washing services.
- Asphalt Roofing: Asphalt is a heterogeneous material with visible components that can be compromised by the high-pressure water jet. These granules once washed off, will compromise the make-up of your asphalt roof, literally destroying it.
- Old Things Made of Wood: Old wood, even if treated, has dry rot in small places that will disintegrate once pressurized water hits it. Even newer wood can be soft wash enough to be damaged by the force of the water hitting it.
- Laminar Sandstone: All other types of stone, such as granite and concrete, can withstand the force of the water hitting it. However, laminar sandstone will easily weather or have grooves appear on it once subjected to high-pressure water.
- Stained Wood: The high-pressure water will wash off the stubborn stains from the wood.
What Different Surfaces Can You do Pressure or Power Wash
The difference between power washing and pressure washing is also about their application. It is an excellent idea to do the spring cleaning for your patios and driveways. However, if you plan to clean concrete surfaces, it is best to use pressure cleaning with the right cleaner or detergent. At New England Paintings, you can be sure we are aware of the surfaces and the type of dirt that power washing needs cleaning-off and to do it safely.
- Power Washer: This is the heavy-duty option. If you plan to clean a big driveway (>100 sqm, for instance) or large areas such as the area around your pool, then this is an option. It works best to clean extreme build-up of dirt, grease, and moss and wash off the slippery surfaces due to mold. Heated water combined with high pressure has a better cleaning effect than pressurized water.
- The heated water can loosen up grime easier and kill mold and moss. However, note that you need to exercise caution when using power washer on surfaces, even for masonry. It is best to consult a professional before doing best power washing to ensure you don’t compromise the surfaces you are cleaning.
- Pressure Washers: This is a safer option, but it takes more time to clean surfaces than power washing. This is best for cleaning smaller surface areas such as patios, decks, or smaller driveways. With proper use and techniques, you can also use pressure washing to clean wood decks, sidings, and tiled areas. With the correct water pressure and in combination with the applicable detergents, pressure washing can clean off dirt and grime from masonry, concrete, and brick safely.
What detergents to use?
If you are not a pro, it is best to study which detergent you want to use because different detergents were formulated to deal with different kinds of dirt on particular surfaces. If you plan to clean your entire yard, expect to use other detergents. Cleaners are the most common and are for remove dirt. Sanitizers and disinfectants are for killing bacteria and any organisms. There are pre-mixed detergents designed for dealing with different types of surfaces.
Note that detergents for houses and sidings will be different from detergents for wooden decks and fences.
How to Do Pressure/Power Cleaning Safely?
Pressurized water coming out of a black nozzles is very dangerous. With a force of 2,000 pounds concentrated at around 1 square centimeter, it is best to exercise caution and not point the nozzle at anything you shouldn’t point at. Moreover, the force of the water ricocheting from a hard surface is still dangerous. Here are pointers to help you ensure safe washing when you do pressure cleaning:
- Never spray at another person. The force coming out of the red nozzles is as deadly as a wooden spear hurled from just meters away.
- Use safety equipment such as goggles or a full face shield when washing.
- Cover all electrical outlets first before doing any washing.
- Ensure that the nozzle is at least five to six feet away from the surface you need to clean and move slowly closer once you know how the surface reacts to the cleaning sequence.
- For instance, clean from the very top going down when you clean walls. This way, you won’t stain the lower surfaces you already cleaned if you did otherwise.
- Use the correct nozzle for the task you want to do. A 0-degree nozzle is for heavy deep-seated grime, while a 40-degree nozzle sprays at a wider area for softer surfaces.
- But for the best and safest cleaning conditions, you can always hire professional washers to do the right job for any surfaces you want to clean. Our power washing company have the experience, equipment, and know-how to clean any surface you need without you having to worry about anything.

Most pressure washer is done during the fall or spring when there is no possibility of freezing weather expected. So, you should do your cleaning during the warmer months.
