Services

Window Services in Long Island

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.

A Wide Service Area

Covering Both Nassau and Suffolk County

Distance and building type both vary more here than in a single borough or county.

NOTE

Long Island covers both Nassau and Suffolk County, so the distance from our Plainview office can vary quite a bit depending on where you are. We plan for that upfront, so travel time doesn't turn into delays.

Most of our work here is commercial, institutional, and multifamily buildings, the same focus as our Nassau County projects, just spread across a wider area. We also work with several window manufacturers, so the product ends up fitting your building instead of the other way around.

FAQ

Frequently Asked Questions

Questions we hear most often about Long Island window projects.

Q1Do you work across all of Long Island, including Suffolk County?

Yes. Our office is in Plainview, in Nassau County, but we install, replace, and repair windows across both Nassau and Suffolk County. We plan scheduling and travel time around your specific location every time.

Q2Does Liberty Window Group actually travel out to Suffolk County?

Yes. Suffolk County is a regular part of our Long Island service area, not an occasional exception, and we build travel time into scheduling rather than treating it as an afterthought.

Q3Is pricing different for Suffolk County compared to Nassau County?

No. Pricing is based on the project itself, the system, size, and scope, not which county it's in. Travel time is planned into scheduling rather than added as a separate cost.

Q4How much does window replacement cost in New York?

Cost depends on the window type, size, material, glass, and how many you need, plus how hard the opening is to reach. Since those factors change so much from one building to the next, we give project-specific quotes instead of a general price range that wouldn't really apply to your job.
