The Importance of Facade Restoration for Preserving Architecture

Preserving architecture through facade restoration preserves a region’s history, legacy, and culture. Facade restoration also protects the environment by reusing existing structures, lessening landfill waste, and using natural resources.

However, while facade restoration encourages the preservation of original materials, building components that are damaged beyond repair or don’t meet current codes will need upgrading or replacement. In addition, all improvements must strive to maintain the original aesthetics and building’s character, by preserving the structure’s and surroundings’ architectural style.

Sto Products has a superior-innovative solution for building facade restoration for preserving architecture – Sto’s The A.R.T. of reStore® program. Sto products also enhance a building’s sustainability, energy efficiency, safety, durability, and occupant comfort level.

  • Rehabilitation typically costs less than new construction.
  • Facade restoration increases the structure’s resale values and attracts business, which can help the economic viability of historic spaces.
  • Facade restoration uses existing space, which quickens occupancy.

Sustainability Advantages of Facade Restoration

Energy Savings

  • No energy needed for new construction and demolition
  • Reuse of embodied energy in building systems and materials
  • Retrofitting allows for more energy-efficient building products, like wall systems, doors, windows, etc.

Recycling of Building Products

  • Lessens the need for new materials, saving natural resources
  • Reduces construction and demolition debris to decrease landfill waste
  • Reduces hazardous debris

Cultural Benefits of Facade Restoration

Facade restoration for preserving architecture helps retain a community’s history, appeal, and aesthetics.

The National Historic Preservation Act (NHPA)

In 1966, Congress instituted the National Historic Preservation Act (NHPA) to mandate the use of historic structures for the public’s benefit and to preserve our national heritage. After it passed, the Secretary of the Interior created the Standards for the Treatment of Historic Properties to guide historic building preservation practice and design in America. Moreover, all grant-in-aid projects assisted through the National Historic Preservation Fund need the Standards for the Treatment of Historic Properties (codified in 36 C.F.R. 68).

The Standards provide four approaches to treating historic properties: Preservation, Rehabilitation, Reconstruction, and Restoration. The approach depends on the property’s historical significance, proposed use, intended interpretation, and physical condition. The standards allow for code-required work to make properties functional, including the sensitive and limited upgrading of electrical, plumbing, and mechanical systems.


Preservation measures aim to sustain a historic structure’s integrity, form, and products. The work includes protecting and stabilizing the building, focusing on ongoing maintenance and repairs of historical components and materials rather than large-scale replacement and new construction.

NOTE: Preservation does not include new exterior additions.


Rehabilitation involves repairing, adding, and altering a historic building while preserving those portions which convey its architectural, cultural, or historical values. Notably, rehabilitation allows for replacing deteriorated features; however, the replacements must match the old color, texture, design, and materials, if possible.


Reconstruction involves designing and building a new structure to match a building’s aesthetics from a specific historical time.


Restoration involves accurately depicting a property’s character, features, and form from a particular time. The process consists in removing building parts from other periods and reconstructing missing components from the restoration time. Additionally, builders can replace deteriorated features with new ones that match the original color, texture, design, and materials.
