Concrete Surface Cleaning

Large sections of concrete flatwork found along retail storefronts, around athletic stadiums, and at commercial/industrial facilities need to be cleaned regularly for three main reasons: to extend the life of the concrete, to ensure safety for foot traffic, and to enhance aesthetics.

Concrete Surface Cleaning Service Overview

Concrete. It’s everywhere.

Concrete flatwork can be found at nearly every commercial property, whether it’s sidewalks around an office building, tens of thousands of square feet in front of retail stores, at a concert venue, on the pool deck at a hotel, around the concourse at a stadium, or just the curbs in a parking lot. It can quickly get dirty with shaded areas growing mildew/algae, fire suppression systems discharging rusty water, inconsiderate teenagers with cans of spray paint, grease from the best burger joint around, tire marks at a car dealership, or any number of other things. Understanding the chemistry of these contaminants ensures the prescription of the perfect alkaline or acid treatment and is essential to the successful removal of stains.

    The Nitty Gritty Details of Concrete Surface Cleaning

    It sounds like you can clean just about anything out of concrete, but what can’t you clean?
    Inorganic stains such as vanadium, deeply embedded tire marks, and others may remain after even the most thorough cleanings. Please note that the removal of all possible contaminant may not be included in a proposed project scope. When in doubt, ask your Account Manager for a clarification of expectations.

    What is your capacity to reclaim and recycle wash water on concrete flatwork projects?
    We own and operate Cyclone CY210 machines as well as the Cyclone TR5500 Recycling Trailer. This technology by Nilfisk allows us to efficiently collect our wash water and run it through a solids separator, an oil/water separator, and a series of 70 and 35 micron filters.

    Is hot water really necessary?
    Heat makes molecules bounce into one another very quickly. The entropy in these circumstances helps break the bond between the contaminant and the substrate quickly. Heat also emulsifies fats and oils. Heat also adds a disinfecting component to our cleanings.

    How soon after concrete is poured can it be pressure washed?
    Freshly poured concrete can be cleaned with mild detergents and low pressure within weeks of the initial pour. High Pressure cleaning of concrete can only be done after the concrete fully cures. The weather conditions on the day the concrete was poured, the amount of hardener used, and access to UV exposure all play a factor here. The brushed on top layer of concrete is always the softest part of the slab and is subject to getting inadvertently etched when cleaned with too much pressure.
    When is it the right decision to seal concrete after it’s cleaned?
    A case can be made for sealing concrete when it is going to be subject to unavoidable heavy contamination, such as high iron content irrigation water near sidewalks at an office park or an outdoor patio at a restaurant.

    How far do my vehicles have to be away for you to complete your work?
    Our preference is 10 feet or more. With 10 feet of clearance, we can safely and effectively pressure wash sidewalks and curbing.

    How often should our concrete be cleaned?
    It depends. Prescribed cleaning cadences are determined by the age of the concrete, the porosity of the concrete, the grade of the property, the proximity of tree cover, and the property’s tolerance for grime. We administer concrete cleaning rotations for properties that range from monthly to every two years

    How does cleaning the concrete make it safer?
    The build up of organic growth and FOG (fats, oils, greases) stains can be slippery. The presence of those contaminants lower the COF (coefficient of friction) on a horizontal surface, making slip/fall accidents more likely to occur. The removal of that organic growth through our cleaning process increases the COF of the surface, resulting in prettier, safer concrete.

    Why does cleaning the concrete make it last longer?
    Concrete that is free of organic growth dries faster after a rain event. Dry concrete does not degrade quickly and it is not subject to cracking in periods of high temperature swings (like when it is 30 degrees in the morning and 60 degrees in the afternoon.)

    • Since meeting Southern Outdoor Restoration at a CAI event in 2018, they have been a pure blessing to work with. Their estimates are clear on the scope of work and pricing has always been better than their competition, in my experience. The work that is completed is always in line with the scope of work and the professionalism of the staff is beyond expectation. The communication throughout the project through completion is unmatched. They have made several of the communities I manage look brand new!!

    • I wanted to apologize for not realizing that the pressure washing was not just the siding, but the patios as well. I moved patio chairs and furniture, etc, but did not remove other smaller things that I thought would not be affected by the chemicals of the wash. When I came home, I realized that the back patio looked spotless and was so grateful that the employees took the time to carefully and creatively move the those items that were in their way.
      Katherine
    • We are very pleased with the job your company did for us. We particularly appreciate being made aware of the clogged downspout at unit 3035, as well as your recommendation for addressing this problem. We were not aware of any remaining issues of this type, as we had earlier paid to have these underground clogs identified and fixed, by moving the drainage above ground. We were obviously misinformed, when we were assured that all those issues had been resolved.
      Ruth
    • Not sure what emails you received on Southern Outdoor. But the gentlemen were were very respectful and did a great job. I was skeptical at first because I help a friend that's in the same business and he always does my property. But they did a very good job.

    • My appreciation is about the conduct of your returning crew. They diligently tried to locate and resolve the issue. When approaching other residents in the complex, they introduced themselves and politely requested help in finding the problem (which had been removed before they arrived). The Board happened to be on the property on other business and each of your team acknowledged us politely as they passed. Please pass my thanks on to your crew. We really appreciate these type of folks working on our property.

    • Carlton just sought me out to let me know what a great and professional job SOR did. He went on to describe the report AND to say he had forwarded the report and his endorsement to people that he thought could use your services. His concluding comment was that SOR did the type of work & service that is just unlike anything in this type of business. A “Raving Fan.”

    • Everything looks great. The community looks better as a whole since your guys have been here. I think everyone is pleased with their work and also their friendliness while performing their job. Thanks again for your help.
      Michael Mims
    • Thank you so much for giving us the opportunity to add on to what you were already doing for our community. The guys did a fantastic job and I'm very pleased with the result.

Have a great day.
      Lori Muchow
    • My gutters in The Meredith Townes Community were cleaned on Sunday morning, April 14. The crew did a great job. Thank you! Cliff was one of the 3 workers and he brought me outside to see the magnitude of my gutter and downspout blockage. When the worker on the roof put the blower in the opening to the downspout, water and debris gushed from the top and from the lower seam of the downspout. Again, Many thanks!
      Fran Carruthers
    • Thank you for being so professional and courteous. I was on my screened porch and did not realize my front storm door was not completely latched. This young man, before he started blowing the debris from the gutters away from my porch, took the time to close my door so the debris would not come into the house. You really do have a great group of men doing some dirty and often dangerous work. Please let them know they are appreciated 😊
      Kathy Messina
    • Please let the gutter cleaning company know that they did a wonderful job. I didn't realize that they had been by until I noticed that my deck was cleaner than it had been. They even closed the gate on my deck.
      Melissa Bowman
    • From my ground-level perspective, it appears that SOR did an excellent job at my location, propitiously at exactly the right time, after all leaves in my area had fallen. They blew off patio and deck thoroughly. Seems like a good outfit. Thanks.
      Dick Robinson
    • Thank you for coming by yesterday and cleaning my gutters. They look fantastic!
      Anne Boney
    • I have never been compelled to write a note of appreciation during a power washing event before. Tarik and Greg are the exception to the rule. I could not be more appreciative of their customer service orientation, their initiative, their thoughtful consideration of what would be best for me and my property and their efficient use of time and effort. Congratulations for hiring and supporting and keeping these great members of your team.
      Nancy Johnson
    • Just wanted to let you know that the board president who lives in one of the townhomes emailed this morning and said he was “very pleased with the power washing of the townhouses”
      Diane Wimpy
      PPM
    • I would highly recommend Southern Outdoor Restoration — our community has been using their services on a continuing basis for about 5 years. They provide us with gutter cleaning; power washing of buildings, concrete surfaces, and street gutters; and deck repair along with power washing and staining. The management and crews are very professional and take pride in their work. Their work is done in a very timely and professional manner. I would highly recommend this company to anyone needing their services.
