Historic Restoration Brings Marlborough’s Iconic Clock Tower Back to Life
Marlborough City Hall, completed in 1905—the same year TWC Phoenix was founded—stands as a symbol of enduring craftsmanship and civic pride. More than a century later, Greenwood Industries and TWC Phoenix came together to restore the historic clock tower to its original splendor. This extensive historical restoration project encompassed both the exterior and interior, preserving the architectural integrity of one of Marlborough’s most iconic landmarks.

Architectural Metal Work Enhances Authentic Restoration
At the tower’s peak, Greenwood’s roofing team replaced the slate roof, while the architectural metal craftsmen fabricated and installed new copper trim around its base—a detail nearly invisible from the ground yet essential to maintaining the tower’s authenticity. These intricate design elements speak to the artistry and attention to detail that defined early-20th-century public architecture.
Skilled Masonry Restoration Ensures Lasting Structural Integrity
The masonry specialists from TWC Phoenix meticulously executed the masonry restoration of the clock tower’s walls, cutting and repointing brick, restoring joints, and applying protective coatings to the terracotta façade. Their work not only revitalized the tower’s historic character but also reinforced its structure for decades to come.

Interior Restoration Revives Clock and Bell
Inside, the restoration continued. The clock face was refinished to its original brilliance, and the bell—long a familiar sound in downtown Marlborough—was adjusted to ring properly once again. Every detail, down to the bell’s tone, reflects the teams’ commitment to precision and craftsmanship.
Accessing the clock tower safely required extensive scaffolding and careful coordination. Project Manager Ken Rondeau described the experience as “the coolest project I’ve ever been part of,” noting how unique it was to enter the tower through the clock face itself. To further enhance safety and maintenance access, Greenwood installed a new interior stair system to replace the aging wooden stairs.
Today, Marlborough City Hall’s clock tower once again stands proudly over the city—its slate roof gleaming, its brick and terracotta restored, and its bell sounding clear. Thanks to the skilled collaboration between Greenwood and TWC Phoenix, this historical restoration ensures that a 120-year-old masterpiece will continue to inspire for generations to come.

Greenwood Industries’ longstanding reputation for excellence in commercial roofing extends to GRS’s work on large-scale public facilities. A prime example is Magazine Beach in Cambridge. The historic brick building, which houses the pool’s facilities, required a new roof in preparation for the busy summer season. GRS installed a durable EPDM roofing system, ensuring the structure is well-protected and ready to serve the community.
Sawmill Restoration: Upon arrival, the GRS team discovered that the historic wooden sawmill was home to a colony of baby bats. The project was temporarily paused to allow the bats to mature and leave the building safely. Once they departed, GRS completed the restoration with a beautiful cedar shake roof, preserving the sawmill’s historic character.
GRS’s work spans every corner of Massachusetts, including offshore projects like Peddocks Island in Boston Harbor. The team replaced the roof on the island’s historic chapel—a project that required unique logistics, including an amphibious landing to transport materials and equipment onto the beach. This successful re-roofing not only preserved the chapel but also showcased GRS’s adaptability to challenging work environments. The team is now preparing for additional projects on the Boston Harbor Islands.
