Plants and/or areas that ought to be protected from the water stream (or chemicals, when using brighteners or sealant remover) are relocated, if possible, or covered in plastic.

High-pressure hoses are brought to the highest level of the building to be cleaned, then lowered to ground level and connected securely to the powerwasher. Garden hoses from the water source are then connected to the powerwasher as well, the water is turned on and the VERY noisy powerwashing machine engine is started. Several powerwashers are often used concurrently to minimize completion time.
