Yes, it is highly recommended to wash a house's exterior before painting to ensure the best results. Cleaning the surface removes dirt, dust, grime, mold, mildew, and old paint, which allows the new paint to adhere properly and results in a smoother, long-lasting finish. Failing to clean can lead to poor adhesion, peeling, and an uneven appearance. Pressure washing is an efficient method for this, but be cautious not to use excessive pressure that could damage siding or wood. For materials like vinyl or stucco, soft washing might be a better option. After washing, allow sufficient drying time, such as three to four days, before painting to prevent trapping moisture, which can cause blistering or peeling.

It is generally not recommended to use dish soap in a pressure washer. Dishwashing liquid is formulated for cooler water, and the warmer water used in a pressure washer can create excessive suds, potentially damaging the machine's tubing and other components. Always check the manufacturer’s instructions for recommended detergents. If you find yourself in a pinch, you can try a highly diluted solution, such as one tablespoon of dish soap per 1.5 quarts of water, to avoid clogging the machine.

Yes, you can pressure wash with just water. The force of the water alone is often enough to remove dirt, grime, and debris from many surfaces. However, for tougher stains like grease, mildew, or algae, adding a detergent or cleaning solution can enhance the cleaning power. Be sure to use the appropriate nozzle and pressure settings for the surface to achieve the best results without causing damage.

Powerwashing services for businesses typically range from $200 to $1,500, depending on surface size, level of grime, and cleaning methods. Heavily stained or high-rise buildings may require additional labor and equipment.
