Double Hung, LLC
Contact: Jackson Hoggard
The original windows found in residential, commercial, and institutional historic buildings can be simple, single pane double-hungs, or elaborate multi-paned showpiece fenestration that the architect originally designed to give the structure distinction and appeal. Some historic structures feature a combination of many different window types. They are all distinct and important historic elements worthy of being retained, restored and improved to keep your building appealing and authentic for generations to come.
All of our processes and products fully conform to the Secretary of Interior's Standards for Historic Rehabilitation. We know what is required to work under the guidelines of the National Park Service and your State Historic Preservation Office to ensure that these valuable tax credits are captured for all of our work.
We have vast experience in undertaking large and small window restoration projects in residential, commercial and institutional settings throughout the Southeast and beyond.
If some of your building's original windows are missing, we are expert at replicating entire window systems in our 20,000 sq ft facility that will satisfy even the most demanding architectural specification.

David Brunsvold
Retired NPS
I have been involved in historic preservation since 1984, working for a residential contractor and then moving to the National Park Service in 1990 working as a blacksmith, carpenter, and woodcrafter. Over the years I have had the opportunity to work on many unusual structures, lighthouses, onion domed minarets, and boat restorations from Puerto Rico to Oregon. I received a Quinque Fellowship in 2004 to travel for two months in Scotland visiting historic sites and meeting with preservation professionals from around the country. In my work with the NPS, I led seasonal crews of up to 10 workers teaching the skills needed to accomplish projects that involved everything from the foundation to the finial on the rooftop. I emphasized the importance of the historic fabric and how the details, for example, window preservation, all contribute to the authenticity of a building. I also attended Beyond Hands-On Instructor Training in 2024.

David Gibney
Jack of all trades and a master of them all. Blacksmithing (bronzecasting, lost wax casting). I first learned historic preservation skills in the 1980's through the "Restoration Workshop", a program of the National Trust for Historic Preservation (NTHP). I managed my own preservation company for 40 years, completing preservation and restoration projects ranging from simple African American churches (Tolson's Chapel, Sharpsburg, MD) to Founding Father's estates (Homewood, Baltimore Maryland and Doughoregan Manor, Howard County, Maryland). In addition to the skills listed previously, I am also able to repair and replace flat plaster, cast plaster, and plaster molding and medallions. I have repaired and reinstalled wood shutters. I have repaired timber frame barns, completed traditional exterior stucco. In my retirement, I have focused on passing on my skills and knowledge through projects with Historicorp and the NTHP's HOPE (Hands-On Preservation Experience) Program. My biggest challenge and greatest reward is working with the Accomplished Arts Apprentices program through the Peale Museum in Baltimore. I am teaching repointing, basic carpentry, and plaster to 10 young adults from marginalized communities, over the course of 16 weeks. In my retirement, I'm sharing my skills and knowledge with anyone willing to learn. I attended Beyond Hands-On Instructor Training in 2024. I live with my wife, Sarah, and dog, Jack, near the Appalachian Trail in Smithsburg, Maryland, where we operate two Airbnb's.

Trevor Thomas
Historic Preservation Training Center, NPS
I have a formal education and professional background in preservation carpentry, with nearly two decades of hands-on experience in the field. Since 2007, I have worked on a wide range of preservation projects for the National Park Service, contributing to the stewardship of nationally significant historic structures. Beginning in 2009, I transitioned into a leadership role, managing complex preservation projects with a primary focus on architectural millwork and traditional woodworking. My work has included the planning, fabrication, and installation of historically accurate components such as windows, doors, balustrades, siding, and ornamental trim—often using historically appropriate materials and joinery techniques. I have collaborated closely with architects, conservators, and skilled tradespeople to ensure that all work meets the highest standards of craftsmanship, historical integrity, and regulatory compliance. Through this work, I’ve developed a deep commitment to the long-term care and interpretation of our nation’s built heritage. Additionally, I attended Beyond Hands-On Instructor Training (BHIT) in 2023.

William Turner
Air Diagnostics & Engineering Inc.
I have spent over 50 years focusing on understanding the Building Science in existing buildings of many different types and teaching. In general, the goal of my teaching activities is to help folks understand how the existing building is or was managing the Water, Air, and Temperature for the building structure and the occupants, and the implications of what the proposed adaptive re-use would have on both the building structure and environment for the occupants or use.
I maintain a Professional Engineers License in Maine, Utah, Wyoming, and Idaho. My specialty is Adaptive Reuse: understanding how Water, Air, and Temperature were managed in the historic building and how the proposed reuse would impact the future life of the building and its proposed occupants.
