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.

Hardscaping is made to withstand the elements, but it still needs regular cleaning as well as maintenance like weeding, replacing broken pieces, removing mold or mildew, and more. Use an appropriate cleaner for the hardscaping material with a stiff brush to remove dirt and other material, or use a pressure washer for a deep clean. Staying on top of maintenance can alert you to any problems with your hardscaping that will need repair or replacement.

If the exterior walls are not thoroughly cleaned before a paint job, the paint could stick to the grime, creating obvious imperfections along the way. Beyond that, painting over a freshly-cleaned wall just about doubles the lifespan of the paint, from three or four years to seven to ten years. 

Even at the lowest setting, there’s always a risk that pressure washing might damage your shower or tub. Never use this technique if there’s pre-existing damage in your shower or tub, like peeling caulk, sealant, or cracked tiles. And skip this method entirely if there are any wood features present.
