Clean Masonry Without Damaging the Material
Stone and Brick Washing in Gadsden, AL & Marietta, GA for walls, walkways, and hardscapes stained by moss, embedded dirt, and organic discoloration
Big Sig's Pressure Washing offers stone and brick washing in Gadsden, AL and Maritta, GA for homeowners and property managers whose masonry surfaces have developed moss in the joints, dirt in the texture, or staining that obscures the natural color of the material. You call when your brick wall has turned gray-green from algae growth, when your stone walkway has dark patches that will not scrub away, or when you need to restore the appearance of a hardscape before listing the property or hosting an event. The company uses controlled pressure and surface-specific techniques to clean without eroding mortar, pitting the stone, or lifting the face of softer brick.
The process involves pre-wetting the masonry, applying a cleaning solution that breaks down organic growth and dissolves mineral deposits, then rinsing with pressure adjusted to the hardness and condition of the material. What you see after the service is the true color and texture of the brick or stone, no longer hidden under years of environmental buildup. In Gadsden, AL and Marietta, GA's humid climate, moss and algae colonize masonry quickly, especially in shaded or damp areas, so cleaning these surfaces also prevents the organic growth from retaining moisture that can lead to freeze-thaw damage, mortar deterioration, or efflorescence as salts are drawn to the surface.
If your brick or stone surfaces look aged, discolored, or overgrown with moss, reach out to Big Sig's Pressure Washing to schedule a cleaning that restores their appearance while protecting the integrity of the material.
How Stone and Brick Washing Differs From Standard Pressure Cleaning
You will see the technician test a small area first to determine the correct pressure level, then adjust the nozzle and distance based on the masonry type and condition. For soft brick or aged stone with crumbling mortar, a lower-pressure soft wash method is used, relying on chemical cleaning rather than force. For harder materials like granite, bluestone, or kiln-fired brick, higher pressure can be applied without damage. A rotary nozzle or wide fan tip is often used to evenly distribute force and avoid concentrating pressure in one spot, which could gouge or pit the surface.
After the service, your brick or stone will look brighter and more defined, with the individual texture and color variation of each unit visible again. Big Sig's Pressure Washing uses cleaning agents formulated for masonry, which target organic growth, mineral staining, and atmospheric pollution without harming the mortar or altering the pH of the surrounding soil. The process also removes the black streaking caused by carbon buildup, tannins from nearby trees, and the green staining caused by copper runoff from gutters or downspouts.
Stone and brick washing does not include repointing mortar joints, sealing, removing paint or graffiti, or repairing cracks and spalling. Those require masonry repair services. The cleaning is most effective on structurally sound surfaces where the primary issue is surface contamination rather than material failure. For historic or delicate masonry, the technician may recommend a gentler cleaning method or lower chemical concentration to avoid altering the appearance or weakening the binder.
Questions About Stone and Brick Washing Services
Homeowners in Gadsden, AL & Marietta, GA often ask how the cleaning affects mortar, how long results last, and whether the process works on all types of masonry.
What pressure is safe for brick and stone?
Pressure typically ranges from 1200 to 2500 PSI depending on the material, with softer brick and weathered stone requiring lower settings to avoid surface damage.
How do you remove moss from masonry joints?
Moss is treated with a biocide or bleach solution to kill the roots, then removed with a low-pressure rinse or soft brush to avoid dislodging mortar in Gadsden, AL and Marietta, GA's older homes.
Why does some brick change color after washing?
Older brick may have surface salts or mineral deposits that mask the original color, and cleaning reveals the true hue that was hidden under buildup.
What is efflorescence and how is it removed?
Efflorescence is a white, powdery salt deposit that appears when water moves through masonry and evaporates at the surface, and it requires acidic cleaners or repeated rinsing to fully remove.
When should you avoid washing brick or stone?
You should not pressure wash if mortar is loose or crumbling, if the brick is spalling, or if the masonry was recently repointed and has not fully cured.
Big Sig's Pressure Washing schedules stone and brick washing throughout the year in Gadsden, AL and Marietta, GA with most requests coming from homeowners preparing for exterior painting, sealing, or property sales.
