The average cost to pressure wash a house is around $310, with typical prices ranging from $200 to $420. However, the total cost can vary widely, from $200 to $750. Power washing, which uses heated water, may cost between $250 and $400 per project, with an average of $200 to $300 for a 2,000-square-foot home.

Key factors that influence the final price include:

• The size and height of the house (a multi-level home costs more than a single-story one).

• The complexity of the job and accessibility of certain areas.

• Geographic location.

• Equipment and hourly labor costs.

Hiring a professional is often recommended as they bring their own equipment and cleaning solutions. Experienced professionals know how to complete the job effectively without causing damage to your siding, gutters, or landscaping, which can be a risk with high-powered water jets.

If your concrete stains are green in color, it indicates the presence of mold or algae—which you should address right away. If left unattended, mold will spread to other areas throughout the home. However, be careful not to disturb mold on indoor concrete surfaces and work with a local mold remediation specialist for specialized care. Once free from mold and algae, seal your concrete to eliminate pores and gaps.

You can certainly utilize a pressure washer to effectively clean your garage floor. If you're dealing with oily residue, consider adding a degreaser to the pressure washer solution. Prior to using the pressure washer, make sure to thoroughly sweep the garage floor to eliminate any loose dirt or debris.

Begin the pressure washing process from the back of your garage, which is closest to your home, and work your way towards the front. This ensures that the water and dirt are directed outside. In case you've applied a cleanser or degreaser, it's a good idea to give the floor another pass with clean water using the pressure washer to ensure a thorough rinse.

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.
