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.

Much like wood siding, it can be dangerous to use a pressure washer on composite siding. While normally durable, composite siding isn’t made to stand up to higher pressure settings. It also makes it very easy to damage the paint or finish on the siding. Some professional power washing companies may take the job on, but we recommend avoiding it, especially as a DIY project with a rented pressure washer.

It takes about 15 minutes per each side of an exterior house to apply detergent and 15 minutes to remove it, so you’ll need roughly two hours for the whole job. However, that length of time may decrease or increase depending on the size of your home, so always budget a little more than expected to ensure you don’t end up rushing to get it done.

You can rinse your solar panels in some cases. For example, periodically rinsing your solar panels can remove light debris if you live in an agricultural or dusty area. Light dust and dirt won’t affect efficiency much, but they can build up and mix with other debris like animal droppings, leaves, and small sticks.
