Looking for pre-paint washing for brick in King of Prussia, PA? We look at the surface first, choose the right method and pressure for it, and give you a price before any work starts. With brick, the right approach is low-pressure wash.
Method and pressure
Cleaning solution: Soft wash for algae and mildew; a masonry-specific cleaner for efflorescence and mortar haze.
What to know about cleaning brick
Brick is tough, but the mortar joints are softer than the brick itself, and older soft-fired brick can pit. Organic growth comes off with a soft wash; mineral deposits such as efflorescence need a masonry-safe cleaner instead of more pressure.
Avoid: Zero-degree tips and close-range blasting that erode mortar joints, and strong acids on brick that hasn't been pre-wet.
How often: Every 2-3 years for most homes.

Do you use high pressure for pre-paint washing for brick?
For brick: usually 500-1,500 PSI with a wide fan tip, held well back from the mortar. What we avoid: zero-degree tips and close-range blasting that erode mortar joints, and strong acids on brick that hasn't been pre-wet. The cleaning solution does most of the work, followed by a gentle rinse.
Is pre-paint washing for brick safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule pre-paint washing for brick?
Every 2-3 years for most homes. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
