Crystal Windows Installation and Replacement in NYC
Crystal Window & Door Systems windows and doors are manufactured in Flushing, Queens, a few miles from where we work every day. Liberty Window Group installs, replaces, and repairs Crystal products across New York City and Long Island, handling everything from consultation and product selection through installation and ongoing service. Our work with Crystal spans multifamily and co-op buildings, affordable and government-funded housing, institutional properties, and commercial and new construction projects.
Crystal Window Services for New York Properties
What we coordinate from the first site visit through final install, adjusted to the building and any compliance requirements in front of us.
We start with a site review of your existing openings and building conditions, then help you work through which Crystal product line fits your performance requirements, budget, and any code obligations tied to your project. Many of the Crystal installations we handle involve coordinating documentation for energy code compliance or funding requirements, on top of the usual product selection and scheduling work.
Once a product's confirmed, we manage ordering, installation, and final review, and we handle repair and maintenance work on existing Crystal installations as well. For occupied buildings, that means working around residents, tenants, and building operations, not around ours.
Crystal Window & Door Product Lines
Crystal organizes its line by material and application rather than by name. We help you navigate that structure based on your building type.
Vinyl Replacement Windows
Suit low-rise buildings and single or multifamily homes looking for an affordable, energy-efficient upgrade to existing openings.
Vinyl New Construction
Built for new builds and full renovations, with the same efficiency and budget advantages as the replacement line.
Aluminum Windows
Hold up structurally in mid- to high-rise buildings, with a sleeker profile suited to commercial and larger residential properties.
Aluminum & Vinyl Doors
Sliding and swing configurations for terraces, balconies, and commercial entries.
Commercial-Grade Lines
Including Crystal's Magnus vinyl series and higher-end aluminum systems, built for larger institutional, government, and high-rise projects.

Liberty Windows' Project Process
Five steps, in order. Timelines vary from one job to the next.
Consultation
We go over your building, project scope, and any funding or code requirements tied to the work.
Site Survey
We check existing openings, structural conditions, and access constraints.
Product Selection
We match Crystal's vinyl, aluminum, or commercial lines to your performance needs and budget.
Order, Documentation & Scheduling
We handle ordering and any code or compliance documentation your project requires, then coordinate the installation schedule.
Installation & Final Review
We install the windows and walk the finished work with you.
NYC Compliance and Energy Code Considerations
Requirements vary by building, funding source, and scope.
Crystal windows are commonly specified to meet NYC Energy Code requirements, and many of the projects we handle also need to account for Local Law 97 emissions and performance standards, particularly on larger multifamily and institutional buildings. Depending on the project, Department of Buildings permits may apply as well.
Affordable and government-funded housing projects often carry their own documentation and approval requirements on top of standard code compliance. We go over what applies to your building and funding source before work begins, rather than assuming every project follows the same path.
