Change is coming

Welcome to PreserveList, Preservation Maryland’s online preservation services directory. This website is currently under construction, but listings are still accessible.

PreserveList was developed to connect preservation service providers with customers that are looking to care for their historic structures.  After the site’s full relaunch on January 1, 2023, PreserveList will be a free service to all, both those looking for preservation services and those interested in listing their relevant services.
