Best concrete driveway pros near Scranton, SC

One of the most important factors to consider when buying a pressure washer is not just psi but also the machine’s overall cleaning power. This is based on both the psi and the GPM. Look for a cleaning rating, or effective cleaning unit (ECU), of up to 8,000 for most residential cleaning projects that require a pressure washer.

You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you’ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the cost to pressure wash your driveway to average between $100 and $350, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.

You can put a gentle cleaner such as distilled white vinegar, dish soap, or a degreaser in your pressure washer in a detergent injector. The attachment will mix your detergent with the water and spray it out. If you have stubborn stains on your driveway, a gentle cleaner in the attachment can help dissolve and remove those stains. Rinse the area with the pressure washer.

Not pressure washing your driveway can lead to several consequences that affect both its appearance and its structural integrity over time:  

• Reduced Curb Appeal: A dirty driveway covered in grime, stains, and mildew detracts from your home's overall appearance.  

• Safety Hazards: The buildup of algae, moss, and mildew creates slippery surfaces. When wet, it increases the risk of slips and falls for you, your family, and visitors.  

• Structural Damage: Dirt, debris, and organic growth can trap moisture against the driveway's surface. In colder climates, this moisture can freeze and thaw, leading to cracks and deterioration of the concrete or asphalt.
