Preserving Your Historic Property

Preserving your historic building can seem like a daunting task. Greater Portland Landmarks and many state and national organizations have developed materials to help building owners as they undertake the preservation of their old building. Landmarks staff can help owners find information on specific preservation technics and materials and connect owners to tradespeople familiar with historic buildings in our Northern New England Preservation Directory. Landmarks’ Advisory Service (link), for a fee, can assist owners with identifying original and replacement materials and features and direct them to resources that can help in any preservation project.


Wooden windows are one of the most important topics in preservation today. Restoration rather than replacement is the greenest strategy. Properly restored windows have a longer life than replacements and retain the integrity of your historic home.
