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.

Depending on the amount of experience you have with power washing or pressure washing, hiring a professional is likely a better option. Using a pressure washer requires a bit of know-how to avoid damaging siding, trim, roofing shingles, and even the seals on your windows. Holding the pressure washer too close to the material you’re cleaning can cause damage to the surface. You can wash your home’s exteriors with a garden hose, but high-pressure cleaning should be done by professionals. 

The ideal frequency for pressure washing depends on the surface being cleaned and your local environmental conditions. For a home's exterior with siding that is safe to wash (such as vinyl, cement, or aluminum), a full wash once or twice a year is a good guideline to remove accumulated dirt, grime, mold, and mildew. You may need to wash more frequently if you live in an area with heavy rain or snow, near a dirt road, or if you notice excessive buildup. Other surfaces have different schedules; for example, a frequently used driveway may need cleaning more often, while outdoor patio furniture might only need to be washed every few years. Use your discretion based on how dirty the area gets.

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.
