Marvin Windows Installation and Replacement in NYC
Liberty Window Group installs, replaces, and repairs Marvin windows across New York City and Long Island. We handle everything from the first site visit and product selection through installation and ongoing repair, coordinating with architects, property managers, and boards along the way. Our work spans commercial, institutional, multifamily, co-op, landmark, and select residential buildings, each with its own conditions and approval process to work through.
Marvin Window Services for New York Properties
What we coordinate from the first site visit through final install, adjusted to the building in front of us.
We start with a site review, checking frame condition, how the opening meets the masonry or curtain wall, and any signs of water or air infiltration. From there, we help you land on the right glass, finish, and configuration for the building's performance needs and budget.
Once a product's selected, we coordinate the spec details with your architect or engineer where needed, then handle replacement, installation, or repair and maintenance. On occupied buildings, that usually means working around tenants, business hours, or public access.
Every project looks a little different on paper. Opening size and shape, existing structural conditions, performance targets from the design team, and whatever approvals apply, all of it shapes what actually happens on site.
Choosing a Marvin Collection
Five collections, each suited to a different mix of design flexibility, material, and performance. Not every collection fits every project.
Ultimate
The broadest design flexibility in the lineup, with natural wood interiors and an extensive range of configurations. Suits custom or architecturally demanding projects.
Modern
Built for contemporary architecture, with narrow visual profiles and large glass areas that maintain strong air and water performance.
Vivid
Transitional-to-contemporary design with dramatic sizing and fiberglass-based durability. Available only in select markets, confirmed per project.
Elevate
Natural wood interiors paired with Ultrex fiberglass exteriors, a lower-maintenance exterior without losing a wood interior finish.
Essential
Ultrex fiberglass inside and out, with a more streamlined set of options for projects that do not need the full custom range.

Installation & Final Review
We install the windows and walk the completed work with you.
NYC Replacement and Approval Considerations
Requirements vary by building, scope, and jurisdiction.
Window replacement in New York City often runs into existing masonry or structural conditions, water management, flashing, and air sealing, especially on older buildings. Depending on the scope, an energy-code analysis may apply.
Buildings in historic districts or with individual landmark status may fall under Landmarks Preservation Commission review for exterior window work, and some replacement work may also need Department of Buildings permits, depending on the project. Not every project follows the same filing path.
Occupied buildings add another layer: unit access, resident or tenant scheduling, and working around business hours. We go over these factors with you early so your timeline reflects what your building actually requires, not a guess.
