Power Washing Older or Historical Masonry

Identify What is to Be Removed


Consider the Historic Appearance of the Building

Consider the Practicalities of Cleaning or Paint Removal

Study the Masonry

Assessment and Planning

  • Condition Assessment: Evaluate the condition of the masonry. Look for signs of damage, such as spalling, cracking, or loose mortar. Identify areas that are particularly fragile.
  • Material Identification: Determine the type of brick or stone and the mortar used. Historic bricks and stones often have different properties than modern materials, and some types of stone are more porous and susceptible to damage.
  • Historical Significance: Understand the historical and architectural significance of the masonry. Consult with preservation specialists if necessary to ensure the cleaning methods align with preservation goals.

Selecting the Right Equipment and Materials

    Pressure Washer: Choose a pressure washer that allows control over the water pressure. For historic masonry, a low-pressure setting (generally between 100-400 psi) is recommended to avoid damaging the material.
  • Nozzle Type: Use a wide-fan nozzle (usually 25 to 40 degrees) to distribute the pressure evenly and reduce the risk of focused, high-pressure damage.
  • Water Temperature: Cold water is usually sufficient. Hot water can be used for stubborn stains, but it must be carefully controlled to avoid thermal shock to the masonry.
  • Cleaning Agents: If necessary, select mild, non-ionic detergents specifically formulated for masonry cleaning. Avoid acidic or highly alkaline cleaners, which can damage the masonry or mortar.


  • Surface Protection: Protect surrounding areas and features that should not be cleaned or could be damaged by water or cleaning agents. Use plastic sheeting, tape, and other barriers.
  • Pre-wetting: Thoroughly pre-wet the masonry with clean water. This helps to prevent the cleaning agents from being absorbed too deeply into the porous material and facilitates the removal of dirt and biological growth.

Test Cleaning

  • Test Patch: Perform a test cleaning on a small, inconspicuous area. This allows assessment of the effectiveness of the cleaning method and ensures no damage will occur to the masonry.

Cleaning Process

  • Controlled Pressure Washing:
    – Start cleaning from the top and work downwards to prevent streaking.
    – Maintain the nozzle at a consistent distance (usually 12-18 inches) from the surface.
    – Move the nozzle in a consistent, overlapping pattern to ensure even cleaning.
    – Regularly monitor the cleaned areas for signs of damage or excessive erosion.
  • Use of Cleaning Agents:
    – If using a detergent, apply it gently with a soft brush or low-pressure sprayer.
    – Allow the detergent to dwell according to the manufacturer’s instructions but do not let it dry on the surface.
    – Rinse thoroughly with clean water to remove all residues.

Post Cleaning

  • Inspection: Carefully inspect the cleaned masonry for any signs of damage. Note areas that may need additional attention or repair.
  • Repointing and Repairs: If any mortar has been dislodged or if cracks have been exacerbated, repointing with a compatible mortar (matching the original in composition, color, and texture) may be necessary.
  • Drying: Allow the masonry to dry completely. This process can take several days, depending on the weather and the porosity of the materials.

Maintenance and Preservation

  • Preventive Measures: Consider applying a breathable water-repellent sealer to protect the masonry from future water penetration while allowing moisture to escape.
  • Regular Maintenance: Establish a regular maintenance schedule to inspect and clean the masonry periodically. This helps prevent the buildup of dirt and biological growth, reducing the need for aggressive cleaning methods in the future.

Special Conditions

  • Environmental Concerns: Ensure that wastewater and any cleaning agents are properly contained and disposed of according to local environmental regulations.
  • Consulting Experts: For particularly valuable or delicate historic masonry, consult with conservation professionals or preservation architects to develop a tailored cleaning plan.

Masonry Cleaning

Checklist for Pressure Washing Historical Buildings

Low Pressure

PSI above 1200 is likely to permanently scar or etch historic masonry.

Weather Conditions

Avoid pressure washing historic buildings between November and March when freezing temperatures can cause cracking.


Low pressure washing is the preferred method for cleaning. Sandblasting should never be used on older masonry.


Conducting a sample test of a proposed cleaning method in an inconspicuous location on the building is strongly encouraged.
