Concrete and Sidewalk Power / Pressure Washing - Why clean concrete regularly? There are both short term and long-term advantages to keeping concrete around a building clean. Sanitation and safety are among the two top reasons to keep sidewalks clean. This process enhances pest control services as well as slip and fall prevention. Keeping organic particles, grease, oil, and anything else that foot traffic will track in and out of office space keeps the inside of the commercial space cleaner longer, and improves air quality. The longer a commercial property goes between cleanings, the more time stains have to settle into concrete pores resulting in concrete that is permanently damaged. The same applies to gum removal. Gum that sits out in the elements will leave a permanent stain if it is not removed quickly. Call today for free an estimate and consultation.
