Commercial Exterior Cleaning: Don’t Miss the End-of-Season Window in Southeastern Wisconsin

The wash season is almost over in Wisconsin! Learn how property managers and business owners can prepare their buildings, patios, and awnings before winter with DeMark’s expert exterior cleaning and pressure washing services. 

If you manage a commercial property in Southeastern Wisconsin, you know the window for exterior cleaning is shrinking fast once fall hits. 

At DeMark’s Window & Pressure Cleaning, we help businesses and property managers tackle those last-minute outdoor cleanup jobs — before snow and freezing temps shut down the wash season. 

Why Fall is the Final Countdown 

Once the temps drop consistently below 40°F, pressure washing and exterior cleaning become limited — both for safety and effectiveness. 

That makes October and early November prime time for: 

  • Building washing – clear away grime, algae, or traffic film on brick, stucco, and siding 
  • Awning and canopy cleaning – extend the life of your fabric by removing mold and debris before winter 
  • Patio, concrete, and entranceway cleaning – boost curb appeal and remove slip hazards from organic buildup 

Whether you manage a strip mall, apartment complex, or office building — a clean exterior sends the right message to tenants and customers alike. 

Let’s get your property looking sharp and protected before winter sets in.
