Efflorescence Removal for Concrete in Milford, DE

Pressure wash with a surface cleaner for concrete. Removing white, chalky salt deposits from brick, pavers, concrete and stone. Typical cost $200-$600.

Efflorescence Removal for Concrete is one of the jobs we do most often in Milford, DE. Typical jobs cost $200-$600, and you approve the price before we begin. With concrete, the right approach is pressure wash with a surface cleaner.

How we clean it

Pressure wash with a surface cleanerCleaning method
Usually 2,500-3,500 PSI with a rotary surface cleaner for even resultsPressure

Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.

Cleaning concrete safely

Plain broom-finish concrete is the surface pressure washing is made for. A rotary surface cleaner gives an even finish without the stripes a wand leaves, and hot water helps with grease and oil.

Avoid: Holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete.

How often: Every year, or every 6 months in shaded, damp spots.

When to book efflorescence removal for concrete

  • White powder or crust on brick, block or pavers
  • Haze that comes back after rain
  • White lines along mortar joints

Why it gets dirty

  • Water moving through masonry and carrying salts to the surface
  • New pavers and concrete still curing
  • Downspouts and sprinklers soaking the masonry

What you can do yourself

  • 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

What can go wrong with DIY pressure washing

  • Washing with plain water, which can dissolve salts and redeposit them
  • Strong acids that burn masonry
  • Sealing over efflorescence, which traps it
