Historic Wooden WIndows Pressure TEsted Performance

In order to pass installation and certification in some of the larger commercial restorations our windows have been placed in testing chambers to prove their durability against other industry products.  So far, we have passed with flying colors.  With the insight from these tests we did add a special weather beating feature to the windows that assists in bridging the gap between historic building methods and modern materials.  If you’re buying a thousand windows, we’ll show you what it is!  We can produce any type of complex multi-pane wooden historic window.

Project Awards:

  • Preservation South Carolina, Honor Award, 2021
  • Spartanburg County Historical Association, Peggy T. Gignilliat Preservation Award, 2021
  • Traditional Building Magazine, Palladio Award for Adaptive Reuse, 2021

  • ENR Southeast, Best Projects Award of Merit for Renovation / Restoration, 2019

In 1924 the Montgomery family, a very prominent family in Spartanburg’s textile manufacturing industry, commissioned Lockwood Greene to design and build the building. Completed in 1925, the 10-story Montgomery Building is one of the first Chicago-style construction projects ever built outside of Chicago.

In 2016, local developer BF Spartanburg came forward with a plan that city officials praised as a “next-level” catalyst for downtown Spartanburg. After engaging McMillan Pazdan Smith on a feasibility study, the development team created plans to restore the 92-year-old, iconic high-rise into a mixed-use retail, commercial, and residential project in the heart of the city’s central business district.

Our design team worked carefully with the National Park Service to meet their criteria for preserving and updating the building appropriately. The building façade’s pre-cast concrete panels were very innovative for their time, making it possibly the only remaining historic pre-cast Chicago-style building in the region. McMillan Pazdan Smith was able to source new concrete panels that replicate the old panels closely enough to receive approval in accordance with the building’s protected status on the National Historic Register of Places. Many of the building’s original Renaissance Revival style architectural details on the interior were also be preserved, including the decorative plaster ceilings and marble floors and walls. The renovated and restored Montgomery Building features 9,000 SF of select boutique retail stores and intimate restaurants on the ground floor. The second floor is dedicated office space, and the eight floors above are residential units, with approximately 92 one- and two-bedroom apartments ranging in size from 422 – 1,374 SF. The CM-At-Risk project was completed in 2019.

Montgomery Building reconstruction to be honored by governor

For two decades, the 127,000-square-foot Montgomery Building, located along downtown Spartanburg’s North Church Street, remained vacant.

After years of neglect, the 10-story building’s precast concrete façade had deteriorated to the point that it was necessary to erect scaffolding along the buildings’ perimeter to protect pedestrians on the street from falling debris.

With the restorative hand of Harper General Contractors and design of McMillan Pazdan Smith, however, the Montgomery Building has reached new heights since its 2018 reconstruction.

On July 23, the team will be recognized by Gov. Henry McMaster in a ceremony at the Statehouse with Preservation South Carolina’s 2021 Honor Award.

“This is one of the most extraordinary projects that has ever been submitted,” Mike Bedenbaugh, president and CEO of Preservation South Carolina, said in a news release. “The challenges that had to be overcome with this building, most of the time, would have led to the demolition of other buildings. That’s why it deserves this award.”

Preservation South Carolina, the S.C. Department of Archives and History, and the governor’s office have recognized accomplishments in the preservation, rehabilitation and interpretation of the state’s architectural and cultural heritage with a series of awards since 1995.

In order to be considered, projects must have been completed, including all phases, within the last three years, made a positive impact on the community and the state, and achieve a degree of project difficulty while serving as an example of outstanding commitment to historic preservation and exemplary preservation techniques, according to the release.

Projects like this are why people like me become architects,” McMillan Pazdan Smith’s K.J. Jacobs, principal in charge and lead architect on the project, said in the release.

Historic Renovation | Replica Wooden Windows

Replica Wooden Windows being built on our shop assembly line.

We have finished one of our single largest historic renovation contracts creating 860 historic replica windows. Built by hand from African mahogany they passed all physical wear and environmental challenge tests before we began building. The Montgomery Building in Spartansburg SC renovated by Harper Construction. Our team has put in overtime, thought through materials problems and worked diligently through some long hours to make sure we met the project deadlines. Thank you all for your skills and dedication!

Built on a Modern Timeline

Gepetto craftsmen specialize in matching and remaking historic pieces for accurate and lasting renovations qualifying for historic tax credits.  While the woodworking may not have changed, people’s expectations as to how long something should take sure have!

The solid mahogany window frames are to the millimeter replicas of the originals, however our bid and the general contractor’s timeline called for a 100 day turnaround on 860 windows.  We had to devise a workflow that built 5 windows a day to meet that timeline!

Wooden windows over 70 inches tall

When the tallest guy on your team can walk through a window frame without ducking, it’s a big job.  The window frames are of pine, and so sourcing stable quality pine planks 8×2″ over 6ft long is also a trick of the trade that you’ll have to hire us to take advantage of fully.  Part of our ability to meet detailed project requirements are our network that sources the raw wood materials right for your construction.  The window frame boxes must be accurately joined to square and plumb and so in the video you see us filling the window frame boxes with the window sashes.  We have a few more trade secret tips for weather sealing and glazing that helped us pass the stress and efficiency tests that were required by the contractor before they signed off on the whole project.  Historically accurate, but meeting modern energy efficiency and weather resistance standards are a modern manufacturing success.

Master Craftsmanship Passed On

Matthew (with the logo t-shirt in the foreground) intently solving the positioning and fit puzzle that manufacturing wood projects presents on a daily basis.  He teaches the craftsmen who are observing the process as well as the sensibility for checking the work. Unlike metals, cement or fiberglass – wood can only be shaped once.  Forming a miter joint must be done with exacting precision or it’s too loose and fails.  The solid wood construction of these windows include over 20 joints that must be tended to individually.  The decision making process of the craftsman guides the fitting and because we have such a large manufacturing scale – the craftsman makes better choices.  If piece A is too tight, he can choose from the source stack of forty or fifty pieces to find a better fit without creating wasted pieces or time.

Manufacturing scale at your service

Contact us to bid your historic renovation and you might be surprised at the price.  We have managed many large construction orders for clients across the Eastern United States.  The windows in the video are shipped to South Carolina where the coastal towns of Charleston and Savannah Georgia have beautiful sections of historic homes.  We supply warehouse and industrial space reconstruction projects in Maryland, Delaware and as far north a Connecticut as the move to re-purpose industrial spaces trends throughout the building and architectural trades.

Project Management

20 years of experience in the field of mill-work has brought Matthew to the level of managing million dollar contracts for large scale production.  Nothing in the wood construction field is quite as organized as you might assume, in the above picture Matthew is measuring and calculating the quantity of raw beams needed to be transported from the warehouse to the shop.  Materials management, time management and building a skilled workforce that can solve problems as they develop in manufacture all contribute to meeting your project demands.

Big Projects Lost in Small Details

Raw lumber comes from raw nature – she’s not perfectly uniform.  These planks are from 8ft to 12ft long and any width from 4 inches to 34 inches!  We have to mill the mahogany from it’s beam size to a 3.8 ” wide window sill.  The plank mahogany will be sorted and ripped before the decorative edge is milled into the side to replicate the historic windows from the 1920’s era building.

Custom built wood skylights

Original skylights were designed in historic buildings to play a significant architectural role in illuminating the magnificent interior spaces below them.  Historic skylights were placed to catch the light not have easy access for repair so and so are poorly maintained.  Biannual inspection and repair are recommended because the work to restore these old skylights often involves rebuilding and re-designing structural elements.  Gepetto craftsmen will use historic methods and materials if requested, or we can blend modern materials with the historic look. Either choice our replacement or restoration will result in decades of service.

Houses designed before electricity

Used windows for light

Something our architects and designers were not forced to do after the turn of the 20th century.  So for houses built after 1900, you are less likely to find skylights and other natural light gathering features because the designer or builder just assumed you would switch on a lightbulb.  Gepetto craftsmen have specialized in renovating, repairing and building true to original wooden skylights in historic homes across Virginia.  Contact us to get a site visit or quote scheduled.

Common repair or replacement issues:

  • glass – single and double pane; historic glass; stained glass
  • glazing and sealing of the wood to glass joinery
  • flashings and skylight to roof joints
  • structural members supporting the elevated glass
  • sealants

Many of mother nature’s subtle and pervasive forces work against a skylight!  Thermal shifting, structural movement from settling or shifting, high UV radiation, wind vibration and water pressure.  The glazing system must defend against all mother nature offers as disturbance. Shed and drain water, support and cushion the glass, avoid mechanical pressure points, and seal against thermal leakage.
