Nassau County is home to Liberty Window Group's own office in Plainview, so it's the area we know best. We install, replace, and repair windows for commercial buildings, office parks, and multifamily properties across the county, alongside select residential projects.
What we cover from the first site visit through final install or repair.
We start with a site review of your existing windows. Then we help you pick a product that fits your building, your budget, and any approval steps that apply.
Once a product is picked, we handle ordering, installation, and a final walkthrough. We also repair and maintain windows that are already installed. We work around your schedule, not the other way around.

Our office is in Plainview, which puts most of Nassau County within a short drive. That makes a real difference for scheduling, follow-up visits, and getting to a job fast if something comes up mid-project.
We work on office parks, commercial buildings, and multifamily properties across the county, and if your project sits further out, our Long Island service area covers Suffolk County too. Between that and our manufacturer partners, we usually have options for almost any building.
We work with several manufacturers, not just one product line. explore all the brands we work with.
