The Preservation Briefs series from the National Park Service is a "reference source"
for homeowners, property managers and architects on rehabilitation topics for older
properties.  The "briefs" cover over 40 specific topics.  

It is strongly suggested that you (and/or your contractor/architect) be familiar with the
topics discussed in these briefs before any repair work is undertaken.  Why?, new
building materials may not be compatible with traditional materials and may actually
be a hazard to the longevity of your property (not to mention the expenses of
re-doing incompatible work).  

These briefs are also important and referenced guidelines when conducting
re-hab work for qualification under various "historic tax-incentive" programs.

The complete set of briefs is available on line at the NPS website.  We have made
available a selected few which cover many of the topics common in Bolton Hill.

For the do-it-yourselfer (or contractor) details and methods of "preservation repair" are provided at the following link: "Historic Preservation Technical Procedures" from the Federal General Services Administration.
