This fall Brian Chappell of Aurelius Restoration Services made significant new progress replicating the type of leader heads that once graced Hyde Hall.
Why are these leader heads worth laboring over?
A leader head is a kind of plenum that allows rain water from the gutters to gather in the box-like top section without backing up. Without the head or box section, water can only go into a narrow pipe and will back up during heavy downpours and run down the exterior walls. It will then soak into the mortar and limestone (yes, limestone is porous) where it will cause damage to both the exterior and interior of the entire wall.
Having already recreated and installed 4 large leader heads on the east façade, Brian has now crafted 2 smaller versions to be mounted on the right and left side of the Portico pediment. Recreating these leader heads and mounting them in the original 1820s holes drilled into the limestone exterior wall will help to alleviate the moisture issues at Hyde Hall, as they will efficiently direct water out of the gutters and into the downspouts that go into the ground and away from the house.
After considerable time spent finalizing the design of the smaller leader heads, in late November Brian installed them on either side of the Portico pediment. These two leader heads, like the four larger ones put up in June, 2019 on the Great House section of Hyde Hall’s east façade, are now functioning as planned.
All of the newly fashioned leader heads are constructed of copper, primed, and coated with the same Acrymax paint used to seal the roofs over the Great House so that they blend in with the roof and stone walls.
Our Hyde Hall team spent over 2 years researching correct styles for reconstructing the leader heads as we had no photos of the tin originals which likely rusted out and were taken down by the 1870s. Working with architects, architectural historians, antiques dealers, and others who provided images and artifacts for us to study and copy, we finally decided that we had come up with an historically appropriate and practical design. Our copper leader heads will be far more durable than the tin originals and should function well for many years. Along with Brian Chappell, members of Hyde Hall’s leader head team included Gib Vincent, Jonathan Maney, Carl Stearns, Jeremiah Rusconi, and Ed Polk Douglas.
In the spring Brian Chappell will create and install 6 more of the smaller leader heads in the Inner Courtyard to complete this project. Funds for this project came from private donors who recognized the need for reproducing as accurately as possible the elements of the drainage system that once worked well to protect Hyde Hall and keep it as dry as possible.
These images follow the progress of design and installation of a prototype leader head at Hyde Hall. In spite of the weather a trial installation was made on November 29, 2018. After evaluation, 5 further units will be installed on the east side of Hyde Hall to funnel water into the downspouts.
