Modern Building Facade

our approach built on collaboration

Fenestration systems connect the building envelope, structure, and architectural design. Replacing them requires coordination between multiple disciplines.

We work closely with engineers and building owners to ensure that fenestration systems are installed according to design intent while addressing the practical realities of construction. Our role is to manage the work on site, sequence and coordinate trades and materials, and ensure assemblies perform as intended once complete.

fenestration services we provide

window wall and curtain wall

Replacement and restoration of large-scale glazing assemblies commonly used on mid and high-rise buildings.

insulating glass

Replacement of double glazing within an existing system, typically on mid- and high-rise buildings.

why fenestration matters


Fenestration systems play an important role in how buildings perform. Windows and doors influence energy use, comfort levels, and the long-term durability of surrounding envelope components.


When these systems begin to fail, they can lead to:


  • Higher energy costs.

  • Air and water infiltration.

  • Interior comfort issues.

  • Damage to surrounding building materials.


Maintaining and improving fenestration systems helps protect building assets, extend service life, and maintain the appearance of the property.

feature projects

Our fenestration work addresses air and water infiltration while improving the performance of windows, glazing, and curtain wall systems. Each project is carried out to ensure proper integration with surrounding envelope components.
