Best pressure washers near Onalaska, WI

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.

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.

It’s not necessary, but you can absolutely use soap or detergent when pressure washing your house. Washing with a mixture of soap and water will ensure your siding is spotless when you’re finished. However, in many cases it is not necessary to use soap and you can still achieve a powerful result without any product. 

Yes, you can use a pressure washer to effectively clean debris, dirt, and grime from your gutters, but it must be done with caution to avoid damage. Always use a low-pressure setting, with a recommended range between 1,200 and 1,800 PSI. Excessive pressure can bend or dent aluminum gutters, damage seams, peel paint, or even knock shingles off your roof, potentially leading to leaks and moisture issues. For a safer alternative, consider soft washing or cleaning them by hand. When using a pressure washer, it is safer to use gutter elbow extensions from the ground rather than climbing a ladder, as the force can cause instability. Due to the risks, you may want to hire a licensed and insured contractor for the job.
