historic preservation

OUR SERVICES

Our historic preservation support includes:

  • Repair and stabilization of historic concrete, masonry, and façade systems
  • Selective replacement of deteriorated elements in accordance with preservation guidelines
  • Structural repairs designed to maintain original materials and assemblies where feasible
  • Sealant, waterproofing, and protection systems compatible with historic substrates

Our work focuses on extending the life of historic structures while respecting their original construction and character.

OUR APPROACH

We don’t modernize, but preserve.

Our approach emphasizes:

  • Understanding original construction methods, materials, and detailing
  • Repairing rather than replacing whenever possible
  • Using compatible materials that won’t accelerate deterioration
  • Meeting modern safety and performance needs while maintaining historic integrity

RESTRAINT AND JUDGEMENT

We take the time to decide what really matters, address the issues that affect safety and longevity, and avoid unnecessary work that can change or damage the structure. That care is what allows historic buildings to keep working, and keep their character, over time.

OUR TYPICAL REPAIRS

Historic preservation work often involves:

  • Repairing deteriorated concrete, masonry, and façade elements
  • Stabilizing cracked or loose materials that pose safety risks
  • Selective steel repair hidden within existing assemblies
  • Sealant and waterproofing repairs that stop water intrusion without altering appearance
