Get matched with top pressure washers in Section, AL

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.

The ideal PSI (pounds per square inch) for a pressure washer depends on the surface you are cleaning. For general home use, a pressure washer with a range of 2,000 to 3,000 PSI is recommended and powerful enough for most residential projects.

The specific PSI you should use varies by task:

• High-Pressure Tasks (2,500-3,000 PSI): Tough materials like concrete, stone, masonry, and brick can handle higher pressures. This is suitable for removing stubborn stains from driveways or cleaning graffiti.

• Low-Pressure Tasks (around 600-1,300 PSI): Softer surfaces require a gentler touch to avoid damage. Use a low PSI setting for cleaning wood decks (especially softwoods like pine and cedar), vinyl siding, outdoor furniture, and stucco.

For best results, choose the right nozzle for your surface, such as a 15-degree nozzle for siding or a surface cleaner attachment for driveways. Using an extendable wand can also make the work easier and more ergonomic.

Brick takes longer to dry than less porous materials like concrete. If you are waiting to spot clean, a full day of mild weather should do the trick. If you are waiting to paint or apply a finish or sealant, give it three to four days to ensure the brick is absolutely dry as a bone. You don’t want any residual moisture whatsoever before laying down paint or sealant. 

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.
