Get matched with top pressure washers in Willmar, MN

Whether you need to winterize your pressure washer depends on where you store it. If you can keep it in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, if the machine will be stored in freezing temperatures, any liquid left in the water pump can freeze, expand, and cause severe damage. To prevent this, add antifreeze to keep it in good condition. While some suggest emptying the machine with compressed air, this can be a tedious process that may not fully drain the liquid. Regardless of storage conditions, it is also good practice to empty the gas chamber and refresh the oil before winter storage.

Experts agree that spring and fall are the best times to pressure wash a home's exterior due to the milder weather. Aim to schedule the project once a year during a warm, dry season, typically between March and November, depending on your local climate. Many prefer the spring to clean away dirt and grime that has gathered over the winter, preparing the house for the rest of the year. You can always perform touch-ups in the summer or fall as needed.

Costs depend on surface material, level of grime, accessibility, labor, and required cleaning agents.

The recommended PSI (pounds per square inch) for cleaning vinyl siding can vary, so it's best to consult the manufacturer's guidelines. Generally, vinyl siding can handle high pressure, from 2,500 to 3,500 PSI. For comparison, more delicate materials like wood and aluminum siding should not face more than 1,500 PSI. To safely disperse the pressure on vinyl, use a tip with a wider spray span, such as a green (25-degree) or yellow (15-degree) nozzle. For routine cleaning of light dirt, a garden hose with a spray nozzle may be sufficient. Always exercise caution to avoid using excessive pressure that could damage the siding.
