Hardware Restoration

Use this CSI 3 part SimpleSpecs™ master specification to specify the repair and replacement of hardware for doors, windows, screens, awnings, and shutters, and weatherstripping and thresholds.


This section includes the most commonly encountered types of metals; brass and bronze for operable hardware; copper and zinc for weatherstripping; and brass, bronze, and cast iron for thresholds. Other metal types can be added by the specifier.


Due to the wide range of historic and replacement hardware, this section provides a framework for specifying new and replacement hardware. A detailed hardware schedule must be developed to suit the individual project’s needs.


This section must take into account the effects of current accessibility codes, laws, rules, and regulations, including the Americans with Disabilities Act, and their effect on door hardware. While some projects may be excluded from compliance, others will need to comply and historic hardware requirements must be modified accordingly.


While reference materials exist on the subject of windows and their hardware, there is not currently available a comprehensive resource for the restoration of historic door hardware. Specifiers should contact manufacturers of period hardware for assistance.


For additional information on this subject, refer to the following Preservation Briefs by the National Park Service, www.nps.gov:


–  No. 9 – The Repair of Historic Wooden Windows.

–  No. 13 – The Repair and Thermal Upgrading of Historic Steel Windows.

–  No. 32 – Making Historic Properties Accessible.

The SimpleSpecs™ master specs concept
Adding More Words Does Not Make Specifications More Enforceable.    
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
  1. The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable.  In fact, quite the opposite is true.  Having shorter, easily understood specifications makes us less likely to have problems in the field.
  2. A belief that having lots of words protects us from a Contactor making mistakes.  There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
  3. Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit

SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.


Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.

Hidden Guide Text

Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.

Streamlined Editing

SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually.  Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
