Building Cleaning
There are a few different kinds and approaches to masonry cleaning.The first and most essential step is to determine the strength of the existing masonry so the appropriate method can be selected. The cleaning process cannot harm the existing surface in any way.

A few different methods of masonry cleaning:
  • Power Washing With Water Only - This technique is frequently used on hard and soft surfaces such as Sandstone, Limestone, Lannon Stone, Concrete. By controlling the amount of water pressure and using the proper tip, it removes surface dirt and mildew staining.
  • Power Washing With Acidic Chemicals - This technique is typically used on hard and soft surfaces such as Sandstone, Limestone, Lannon Stone, Brick, Concrete. Applying an acidic chemical to the surface removes the chemical with high pressure water. It removes surface dirt, heavy dirt, mildew stains and carbon stains.
  • Sand Blasting With Air Pressure - This technique is often used on only hard surfaces such as Lannon Stone, Field Stone, Steel by using a fine grade sand and high air pressure. It removes heavy mortar smears, paint, tar, rust, carbon, surface dirt, and mildew stains.
  • Power Washing With Sand Mixture - This technique is usually used on hard and soft surfaces such as Sandstone, Limestone, Lannon Stone, Field Stone, Concrete, Brick. We mix a fine grade sand with controlled water pressure so when the two hit the targeted surface they are very soft but very extremely effective. This method removes surface dirt, mildew staining, light flaky paint, rust, and light to medium mortar smears.
