When we handle efflorescence removal for brick in Knoxville, TN, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end. On brick, the method we use is low-pressure wash.
How we clean it
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.
When to book efflorescence removal for brick
- White powder or crust on brick, block or pavers
- Haze that comes back after rain
- White lines along mortar joints
What causes the dirt and stains
- Water moving through masonry and carrying salts to the surface
- New pavers and concrete still curing
- Downspouts and sprinklers soaking the masonry
Easy upkeep between cleanings
- Brush dry efflorescence off with a stiff brush before wetting it
- Fix water sources such as gutters and sprinklers
- Wait out new installations: efflorescence on new pavers often fades on its own

Why more pressure isn’t better

Efflorescence Removal for Brick in Knoxville, TN
Rust stains from sprinklers fed by well water are common in Tennessee, along with tannin stains from leaves and the dark film mildew leaves on concrete.
Red clay soil is common in parts of Tennessee. Rain splashes it onto the bottom of the siding, walls and walkways, and its iron-rich color can stain light surfaces. It usually needs a dedicated clay or rust cleaner rather than pressure alone.

Do you use high pressure for efflorescence removal 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 efflorescence removal 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 efflorescence removal 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.
