Concrete is similar to a kitchen sponge in that its porous nature soaks up water and dirt and creates an environment for mold and mildew to grow. The pores are a natural element to forms during the curing process of the concrete as the water evaporates out of it. Over time, rain pulls dirt, salt, and other contaminants through the concrete pores making it look dingy over time. To make things worse, during the winter when the water freezes, it grows — by 10% — causing breaking, chipping, and spalling. The damage this causes is a big problem with the repair cost of a concrete driveway in the thousands of dollars to replace and weeks of hassle not using a driveway.
“You can maintain concrete and avoid having to replace or your repair concrete driveways or walkways by having yearly pressure washing done by professionals”, says Jonathan Brandle owner of Grime Stop Owensboro Power Washing company.
Depending on the size of the Minneapolis concreate driveway, the cost is around $80 to $200 to have a professional pressure wash a driveway. Pressure washing a driveway or walkway not only keeps extends the life of the concrete but it also gives it a nice clean look and so it has become a popular service among home owners.
