Common Historic Masonry Problems
Mortar Deterioration
Our certified masonry professionals conduct thorough inspections using advanced diagnostic tools to identify the root causes of foundation problems. We provide detailed reports with photographic documentation and recommended solutions.
Water Damage
Moisture infiltration can cause significant damage to historic masonry. We identify water sources and implement conservation-appropriate waterproofing solutions.
Structural Movement
Settlement, foundation issues, and structural loading can cause cracks and displacement in historic masonry. We address these issues while preserving the building’s historic integrity.
Environmental Deterioration
Pollution, freeze-thaw cycles, and weathering can accelerate masonry deterioration. We provide protective treatments and repairs that slow future deterioration.

Frequently Asked Questions About Historic Masonry Repair
How much does historic masonry restoration cost?
Historic masonry work typically costs 20-50% more than conventional masonry due to specialized materials, techniques, and documentation requirements. Costs range from $15-150+ per square foot depending on the complexity of work. However, tax credits and grants can significantly offset these expenses.
Do I need special permits for historic masonry work?
Yes, most historic buildings require special permits and approvals from local historic preservation commissions or state agencies. We help navigate the approval process and ensure all work meets preservation standards.
Can you match the exact appearance of original masonry?
Yes, through careful materials analysis and traditional techniques, we can create repairs that are virtually indistinguishable from original work. We take great pride in maintaining the authentic appearance of historic buildings.
How long does historic masonry restoration take?
Projects typically take longer than conventional masonry work due to specialized techniques, materials curing times, and documentation requirements. Small projects may take weeks, while major restorations can span months or years.
What makes historic masonry repair different from regular masonry work?
Historic work requires specialized knowledge of traditional materials and techniques, compatibility with existing historic fabric, regulatory compliance, and extensive documentation. We use period-appropriate methods that preserve the building's historical integrity.
Can modern materials be used in historic masonry repair?
Modern materials must be carefully evaluated for compatibility and appropriateness. Generally, we use traditional materials like lime mortars rather than modern cement mortars, which can damage historic masonry through excessive hardness and impermeability.
Do you work with architects and preservation consultants?
Absolutely. We regularly collaborate with architects, engineers, and preservation consultants on historic projects. This team approach ensures the best outcomes for complex preservation projects.
What documentation do you provide for historic work?
We provide comprehensive documentation including condition assessments, materials analysis reports, treatment plans, progress photography, and final reports suitable for preservation agencies and future building maintenance.
