Texas Gravestone Conservation
Texas Gravestone Conservation


In the past four years, I have done several presentations to historical and genealogical organizations who were interested in my work, or who wanted some instruction for their members before starting on a cemetery cleanup in their area.


I am willing to share my knowledge and experience with your group and do cemetery walks to advise you on what can be done by trained and willing volunteers; I will also hold training/workdays with members to demonstrate "best practices" in gravestone conservation.  Similarly, if you would like for me to speak to your group, I have a PowerPoint presentation of some of my jobs and can follow up afterwards with a question-and-answer session for those wanting to learn more.  While some conservation work should be reserved for a skilled conservator, many simple things like cleaning and straightening can be done by properly trained volunteers.

Conservation and Old Repairs

Repairs made to gravestones in the early 20th century vary widely.  Some were done well, while others were done by individuals with more ambition than skill.  Almost all methods from 100 years ago have been supreceded by modern materials, tools and techniques, and sometimes the old repair can still be 'undone' to better conserve the stone.


Below are two photos of the same piece of a tablet stone.  The person who repaired the stone the first time used Portland cement-based mortar as an adhesive to "glue" the two pieces together; in doing so, he did not clean the mortar from the lettering, and thus, covered it.  The original repair failed and another was done later with a foaming glue which also failed. I was hired to conserve the stone, and while the stone was in my shop, I decided to carefully attempt to remove the mortar and allow the inscription to show.  After four hours of work, the mortar was removed with no harm to the stone or the lettering.


I will post a photo of the stone when conservation is completed.

As of Oct 22, 2018, I am not taking on any more projects.  The summer heat and weeks of wet weather has put me behind on the ones I already have comitted to.  This DOES NOT MEAN that I am not interested in projects for later in 2019, just that until I get caught up, I'm not contracting with individuals or groups for more work.

Thoughts for Fall

Why is it such a bad idea to just pour concrete around all the stones in a plot?  Aesthetics aside, old stones (such as marble and limestone) will be damaged by the incompatible material through long-term curing/hardening, and thermal changes.  As well, some people have the idea that concrete and Portland cement based mortars are adhesives; they are not.  If you don’t believe it, look at the photos of the mortar that was on a marble tablet and the photo of the same tablet with the mortar removed on the     "Workshops & More Photos" page of this site.  If it was an adhesive, then it failed.  Cement will also hold water, causing a slow degradation of the natural stone it is in contact with.
