The Right Pressure for Every Surface
Charleston's humid climate is rough on exteriors. Mildew creeps up siding, oil stains darken concrete, gum sticks to sidewalks, and grime builds up on signage. Left unchecked, it makes even a well-run business look tired and uninviting.
Our crews bring two solutions: high-pressure washing for hard surfaces like concrete sidewalks, parking lots, dumpster pads, and entryways — and soft washing for delicate surfaces like building facades, siding, awnings, and signs. Soft washing uses low pressure paired with biodegradable cleaning solutions to safely lift dirt, mildew, and algae without damaging finishes.
From a single dumpster pad to an entire shopping center exterior, we'll match the right method, equipment, and schedule to your property — restoring curb appeal and protecting your building from long-term damage.
