What exterior surfaces should never be cleaned with high pressure?
Quick Answer
Pressure washing is great prep but some exterior materials should never see high pressure. Avoid blasting roofs, windows and doors, soft or aged wood siding and decks, vinyl siding seams, stucco or EIFS, and older brick or mortar joints. High pressure can strip paint, etch surfaces, and drive water behind walls.
Detailed Answer
Pressure washing Northeast GA homes is a smart way to remove dirt and mildew but high pressure is the fastest way to cause damage. Never use a tight, high-pressure spray on:
- Windows, doors, screens, soffit vents, and caulked joints
- Soft or weathered wood siding, trim, and decks
- Vinyl siding seams and lap joints (water can get behind panels)
- Stucco, EIFS, and older brick or mortar joints (can chip or etch)
- Exterior electrical fixtures, outlets, and HVAC fins
For these areas, a soft wash or low-pressure rinse is safer. On wood siding, keep pressure low (often under 1500 PSI), hold the nozzle at least 12 inches away, and use a steady sweeping motion. Let everything dry fully before any exterior painting.
