Ashi-Certified Inspector Scott T. highlights the potential risks of pressure washing through a revealing video. The video showcases instances where pressure washing caused damage to wood decks and vinyl siding. While pressure washing can be effective in cleaning surfaces, excessive pressure or incorrect techniques can lead to unintended consequences. Wood decks can be stripped of their protective layers, leading to splintering and deterioration. Vinyl siding can be cracked, warped, or dislodged, compromising the structure's integrity and aesthetics. Scott T.'s video underscores the importance of using appropriate pressure and techniques to safeguard surfaces from unnecessary damage, ultimately preserving the value and appearance of properties.
