Most commonly, when we come across damage from high pressure it is on surfaces like siding, screens, and wood. These surfaces never should have been cleaned with the use of pressure to begin with. Surfaces like the ones listed throughout this page that often require the use of pressure can become damaged as well. The most common damage we see on these surfaces is etched lines caused by excessive pressure. We also come across many damaged mortar and sand joints. Hiring a professional company like us will give you the peace of mind that your property is in good hands.
