Pressure Washing Keeps Your Exteriors Crisp & Clean
Are layers of dirt, mold, grime, grease and other unsightly build-up accumulating on your building’s exterior walls, sidewalks or parking lots? Has your property been defaced by graffiti? Do your exterior walls need to be prepped for painting? Or do you want to keep your property looking fresh and clean? If you answered yes to any of these questions, then you are a prime candidate for professional pressure washing services!

Pressure washing is one of the most cost efficient and effective ways to maintain and restore your facility’s exterior assets, and protect those assets from the harsh effects of environmental and man-made elements. Sunlight, wind, rain, snow, ice and various air toxins produced by pollution and emissions can reap havoc on your property’s curb appeal and cause long-term damage. Pressure washing effectively decreases the probability of long-term damage by removing the unsightly build-up and keeping your exterior assets in prime condition throughout the year.

Pressure washing service includes the application of high-pressure water spray performed on:

  • Private & municipal sidewalks
  • Parking lots, garages & spaces
  • Curbs
  • Inside & outside stairwells & handrails
  • Exterior building walls
  • Monument signs
  • Loading docks
  • Overhangs

Parking lots and garages, or portions of these structures, should be pressure washed twice annually or as needed to prevent accumulation of grease, oil, gum and other staining agents. Regular pressure washing maintenance and sealing will prolong the life of these assets, reducing your long-term expenses and make your property more safe and inviting.

When the goal is cleaning the building’s exterior walls to remove unsightly build-up, customers are often concerned about damage to their painted surfaces and do not view pressure washing as an affordable, effective solution. But, there’s nothing to fear if you work with a reputable, professional pressure washing company. A professional service provider will utilize the proper equipment and cleaning techniques to avoid damaging your exterior paint. Build-up of mold, mildew and other environmental or man-made elements actually deteriorate your paint more rapidly, so it’s important to utilize low-pressure exterior cleaning on a regular schedule to clean and prolong the life of your painted surfaces for up to two years.

On the other hand, when the goal is paint and graffiti removal a professional provider will use a high pressure spray (3000-5000 PSI) to effectively remove the graffiti or strip old paint to prepare surfaces for a fresh coat.

Many people do not realize that one of the most effective ways to prevent future vandalism, protect the image of your property’s neighborhood and preserve customers’ sense of security is rapid and continuous removal of the graffiti. Studies have shown that graffiti removal completed within 24 to 48 hours results in a nearly zero rate of recurrence

Buildings should be cleaned a minimum of twice annually to remove stains and prevent deterioration caused by exposure to environmental and man-made elements, which can result in costly paint and masonry repairs and turn customers away.

Concrete areas such as sidewalks, stairwells, curbs and entryways can be restored to an almost new appearance with pressure washing. Not only is the curb appeal enhanced, but removal of mold, algae, and oil can also help reduce the risk of slip and fall accidents.


  • A well cleaned property has increased curb appeal
  • A mildew free wooden fence/deck lasts longer
  • Paint free of mold, mildew, and dirt looks better and adds years to the paint coating
  • Adds years to canvas and vinyl awnings
  • A clean storefront will increase traffic to your business
  • Concrete is not as slippery without mold
  • Reduce safety concerns
