A landmark restoration is a big project that needs big financial backup. This particular type of restoration project is usually required and conducted by property owners for historic preservation and for the construction industry.
Though landmark restoration of a historic home can be very daunting, many homeowners find it worthwhile because of the tax breaks, national and local grants that come along with the project.
For this to be successfully done, thorough research of the history of the landmark needs to be done. You can look for photos and old records of the home in news archives and even in your local library. In case you could not find any record or photos, try researching for the era in which the house was built and see what similar homes looked like. By doing so, you can have a reference of the original appearance of the house. Restoring it would be easier then as you have a guide to follow.
But before continuing with the landmark restoration project, have the home inspected first for any structural issues, wiring and plumbing problems.
Since it is a landmark, it is necessary that it is restored in its original configuration. Do that by removing anything that seems inappropriate such as additional porches, awnings and shutters. Do the same thing with interior moldings and other details that have been added. For the doorways and windows, remove any coverings and restore them to their original form.
The roof and porch railings that may be damaged have to be repaired or replaced. It is recommended that these parts are repainted using the color that is true to the home's era. Sticking to the typical colors used in the home's era is important.
Flooring needs to be restored as well. If the floors can be refurbished into their original state, replace them with matching materials. The same goes for all fixture and hardware. Remember to use originals and matching materials only to properly accomplish this project.
