Delicate Structures Cleaned Without Damage
Historical Building Restoration in Arlington for protected properties, heritage structures, and buildings with original materials requiring preservation
Older masonry absorbs water differently than modern brick because historical lime mortars remain porous while the fired clay becomes denser with age, meaning standard high-pressure cleaning drives water deep into wall assemblies where it can dissolve salts, freeze during winter, and cause spalling that destroys original material. Pierson Pro Wash LLC approaches historical building restoration in Arlington with methods that remove decades of carbon deposits, biological growth, and atmospheric soiling without saturating substrates or eroding the soft mortar joints that hold century-old walls together. The work preserves what remains rather than accelerating the deterioration that inappropriate cleaning causes.
Historical structures require assessment before any cleaning begins because each building presents different conditions based on original construction methods, previous maintenance history, and the specific types of soiling present. Gentle techniques remove surface contamination while respecting the integrity of materials that cannot be replaced if damaged during restoration work.
Request an initial consultation to evaluate your building's condition and determine appropriate restoration methods.
Historical buildings accumulate layered soiling over decades, with each layer telling part of the structure's story through carbon deposits from coal heating, biological growth in areas with chronic moisture exposure, and mineral staining from metal components that have corroded over time. Cleaning removes these deposits using low pressure, controlled water temperature, and extended dwell times that allow cleaning agents to work chemically rather than relying on mechanical force that can damage friable surfaces.
After restoration cleaning is finished, original brick color and texture become visible again, decorative stonework details emerge from beneath grime that has obscured them for generations, and the building's architectural character is revealed without the visual noise that heavy soiling creates. Pierson Pro Wash LLC removes contamination while leaving patina and aging characteristics that contribute to the structure's historical authenticity.
The service does not include structural repairs, mortar repointing, or the replacement of damaged materials, focusing instead on cleaning existing surfaces to prepare them for documentation, further restoration work, or simply to improve appearance while maintaining historical integrity. Buildings with preservation easements or landmark status often require approval before cleaning, and appropriate methods must be documented to satisfy regulatory oversight.
What Property Owners Usually Ask
Owners of historical properties and preservation organizations commonly have these questions about restoration cleaning.
What makes historical masonry more vulnerable to cleaning damage than modern brick?
Lime-based mortars used in construction before the mid-twentieth century are softer and more porous than Portland cement mortars, making them susceptible to erosion from high pressure or aggressive chemical treatments that modern materials can tolerate.
How is cleaning effectiveness measured without causing harm to original materials?
Test areas are cleaned using progressively stronger methods until optimal soil removal is achieved at the gentlest effective intensity, establishing parameters that guide the full project without risking overcleaning or surface damage.
When should historical building cleaning occur relative to other restoration activities?
Cleaning typically happens after structural repairs and repointing are complete but before final protective treatments or coatings are applied, allowing assessment of the cleaned surface before preservation measures are implemented.
Why do some historical buildings in Arlington show more biological growth than others of similar age?
Buildings with northern exposure, proximity to vegetation, or roof drainage issues experience sustained moisture that supports mold and algae growth, while better-maintained structures with proper water management remain relatively clean despite their age.
How does restoration cleaning affect buildings listed on historic registers?
Proper cleaning preserves the materials and appearance that earned the building its historical designation, while inappropriate methods can cause irreversible damage that diminishes both architectural integrity and historical value.
