Limestone cleaning services have been used to keep important buildings like the Lincoln Memorial, the Pentagon, and the Empire State Building looking great for decades. The fine grains of limestone rock give it a density that results in a centuries-old lifespan. The natural material is also an essential component of concrete and is highly valued by architects and builders for its beauty, strength, and durability.
That doesn’t mean, though, the material doesn’t come with some common problems:
- Weathering occurs when rainwater interacts with the mineral calcium carbonate in the limestone.
- Erosion due to improper handling, including during limestone cleaning services.
- Staining, or “discoloration of limestone” from the different organic and inorganic oils limestone absorbs.

Years of Experience Performing Limestone Cleaning Services
As a seasoned contractor in the limestone cleaning services arena, Presto has serviced countless mid- and high-rise buildings with limestone facades. Our decades of experience in providing this service has given us great insight into which methods and chemicals are the safest and most effective. Our skilled technicians are extensively trained in the material as a whole and understand the means and methods associated with successful stain removal on the stone’s surface.
Unfortunately, we’ve seen a lot of damage to facades which can usually be attributed to other contracting services’ inexperienced technicians employing improper limestone restoration techniques. Our extensive experience and gained wisdom make us an ideal provider of limestone cleaning services for your building.
The Limestone Cleaning Services Process
Limestone is a natural material that comes in a variety of color variations such as tan, gray, blush, or pink. Limestone surface finishes include smooth, sandblasted, machine-tooled, and more, and each finish can alter the stone’s color, creating deeper, richer hues.
There’s a wide range of chemicals that can be used to provide a clean appearance to the exterior of limestone. Because the material is easily damaged by acidic products, it’s important to choose cleaning chemicals that protect its beauty and structure. It’s also important to avoid using high-pressure on limestone which might result in an uneven appearance that is difficult to remove, making it a permanent feature throughout the facades’ lifetime.
Presto’s experience with limestone cleaning chemicals is unparalleled in the industry. We also manufacture our own cleaning detergents and other stone restoration products with each one uniquely formulated for the high-rise commercial facade it will be used on. The chemical cleaning methods and techniques we use for your building depends on its individual needs.
While delivering our limestone cleaning services, we always use chemicals that have been tested on the specific surface, and that has proven to be effective for the surface’s particular staining. For instance, atmospheric staining that occurs in city environments typically requires a different cleaner than biological staining that occurs in humid areas.
A great example of this is the work we did on a 15-story commercial tower in Puerto Rico that was built using a rare type of limestone travertine panels. Previous attempts to clean the biological growth employed chemicals more suited to atmospheric staining. Unfortunately, local contractors were damaging the material without removing the stain. Presto provided a product (Stone Restore CB2) and technique recommendations that successfully restored the impressive landmark.
