The Texas Capitol is more than an historic landmark; it serves as the seat of government for the state. Due to the status, size and age of the building, the Capitol and Capitol Extension require constant attention. The dedicated and skilled staff of the State Preservation Board preserves and maintains the Capitol and Extension both for its current occupants and visitors as well as for future generations.

The Texas Capitol Roof Replacement

2022 to 2024

The Texas Capitol Roof is being replaced in its entirety for the first time in 75 years. Leaks have increased as the roof has aged, putting the building, its systems, and priceless artifacts below at increasing risk of water damage. Extensive inspections have confirmed existing conditions and failure mechanisms to inform the best replacement design. Work includes replacement of all standing seam copper, three skylights, updating access and safety elements, addressing water infiltration through air vents, upgrading roof-mounted lighting and legislative chamber ceiling lighting to LED, and improving protection against lightning strikes. There will be minimal work on the dome, last painted and repaired in 2010. Work is planned to last a little more than two years, conducted in phases. Historical accuracy is being considered in all decisions to maintain and restore appearance to the ca. 1915 interpretation period. Quality assurance will be essential to the process, ensuring the many complex details are properly executed to protect the Capitol for several generations to come.

Handrail Refinishing

Status: Current 2022

The original 1888 Bois D'Arc handrails topping the balusters of the grand stairs of the Texas Capitol will be carefully refinished. This unique wood is prized for its both its hardness and flexibility. These characteristics made it the perfect choice for this unique application, which receives much handling and abrasion. Mockups of several finish systems were tested to minimize impact on the original wood, while providing a durable and maintainable coating that will protect this unique historic feature while showing off its distinctive grain and color.


Fun facts:

  • The designer of the Capitol Grounds, William Munro Johnson, patented the use of Bois D'Arc street pavers which were used extensively in Dallas, where he was the city engineer.
  • It was used by Native Americans for bows, which is the origin of its primary name, French for "bow wood."
  • The fruit of this tree required mastodons to ingest them to spread their seeds during the last Ice Age.
  • Also known as Osage Orange, it is a native Texas tree species with a range centered in northeast Texas and spreading into neighboring states over the ancestral territories of the Osage Native American tribe.
  • Yet another name of this tree species is Horse Apple, for its large, hard and bumpy fruits which were superstitiously used for pest management.
  • It has a fourth name, Hedge Apple, due to its historical use in dense linear plantings that created impenetrable barriers before the invention of barbed wire for fencing. The strong, rot-resistant wood was also used for fence posts.
  • A large Bois D'Arc tree is part of the Trail of Trees on the Capitol Grounds.

Elevator Modernization

Status: Complete 2021

Modern systems in the historic Capitol require maintenance as well as the historic material. Elevators in the 1888 Capitol and 1993 Capitol Extension were recently modernized to current code.

While much of the work remains largely hidden from the public in machine rooms, visitors will now enjoy updated controls and modern features such as audible floor announcements for people with visual impairments, as well as improved wayfinding elements. Modern motors will be more durable, energy efficient and easier to maintain.

Along with the equipment, the cab interiors were replaced after 25 years of use. The opportunity was taken to add a new decorative and interpretive feature in the elevators off the Capitol Rotunda: an actual-size replica of the glass seal in the oculus of the Capitol North Façade pediment. While still in place, the original glass seal is very far from viewing locations at ground level, and has been protected with a backing that renders it no longer transparent, making it even less visible. At its construction, both the north and south Capitol facades featured decorative glass in their oculi, which were piped for gas fixtures to backlight them at night.


Exterior Door Preservation Project

Status: Complete 2018

The exterior doors that greet visitors to the Capitol are original 1888 construction. In addition to facing sun, rain, and wind for the past 130 years, they are currently used by more than 1 million visitors per year. Built of a thick layer of oak laminated over a core of white pine, the doors are hung on the largest of the massive "Texas Capitol" hinges found throughout the building.

This year, the SPB conducted a preservation effort on these important historic elements. The sensitive treatment included stripping loose paint, patching cracks and nicks, replacing perimeter sealants, and applying a fresh coat of protective paint to the exterior. Sweeps were replaced at the bottoms of the doors to keep out air and insects. New closers were installed to make these massive doors as easy as possible to open, while keeping them securely shut to keep out the elements. All historic hardware was restored to smooth function. Attachment points of hardware were reinforced to protect adjacent historic wood, and catches were adjusted to accommodate each door's unique shape without placing them under stress.

Capitol Exterior Deck Replacement

Status: Complete 2018

The State Preservation Board (SPB) is currently replacing exterior decks at the Texas Capitol. These include the east and west exterior pedestrian entrance decks and the elevated decks at the north porch on the second and fourth floors. In Elijah E. Myers's original design, the east and west decks were to be covered with porticos similar to the existing north porch. The porticos were removed from the design in 1885 as a cost savings measure when changing the exterior stone from limestone to granite.

Currently, these decks serve as walking surfaces, but are also effectively roofs over the spaces below. Their waterproofing systems need replacement, 25 years after their installation in the comprehensive Capitol Restoration of the early 1990s. Water carrying damaging salts has been infiltrating through the decks into the structures below. As a result, SPB has observed rusting of important wrought iron structural elements, failure of mortar and plaster in the brick ceiling vaults and erosion of the original historic limestone walls below.

Capitol Visitors Wayfinding Signage Package

Status: Complete 2018

In 2018, the SPB will install a signage upgrade extending from the Visitors Parking Garage, across the Capitol Square grounds, and into the Capitol. The intent of the signage is to improve the visitor experience with a focus on improved wayfinding for visitors with physical impairments. The Garage will have improved directional signage making the facility easier to identify for visitors arriving by car, and wayfinding signage indicating how to move toward the Capitol, once parked. Informational kiosks outside the garage will provide additional wayfinding elements, as well as historical information about the Capitol and Capitol Square. Once on the historic grounds, signage will be minimized to protect the historic landscape. New elements will include maps at each entrance and more frequent wayfinding signage along the sidewalks indicating accessible routes to all destinations across the Grounds. Inside the Capitol, minor detached signage will be added at entrances, elevators and hearing rooms to improve queuing and security screening and encourage priority access for visitors with disabilities.

Exterior Preservation Project

Status: Complete 2015 - 2016

The Capitol's finely crafted windows retain significant elements of their original wood and plate glass. In 2015, the Preservation Board began to repair and stabilize more than 700 frames and windows. The entire exterior masonry surface will be gently cleaned and thoroughly inspected. Stone will be repaired, and mortar joints repointed as necessary. This undertaking requires an elaborate scaffold and multiplatform design to address each of these irreplaceable pieces.


Mortar Repair

During a inspection of the Capitol's exterior, staff discovered erosion of a mortar joint in the pediment due to water damage. Workers re-pointed the joint using a compatible mix of Portland cement for stability and lime to accommodate movement of stone. Inspections of this and other similar areas of the building take place on a scheduled basis to ensure the stability of the building.


Senate Chamber Carpet

Status: Complete 2014

In 2014, a reproduction of the Senate Chamber’s c. 1902 historical wool carpet was loomed and installed to replace the previously well-worn reproduction. Installation including hand sewing together 27 inch strips of carpet. The project did not use tax dollars. Funds generated from parking revenue, gift shop sales, concessions from the Capitol Grill and lease payments paid for the repairs.


Dome Repair and Re-painting

Status: Complete 2010

In 2010, scaffolding covered the entire dome and cupolas. Workers painted the dome to match the color of the Texas Sunset Red granite and undertook substantial water-proofing, asbestos removal and metal refurbishing. The project did not use tax dollars. Funds generated from parking revenue, gift shop sales, concessions from the Capitol Grill and lease payments paid for the repairs.
