What Bethpage's climate means for your window spec
Bethpage sits in IECC climate zone 4A, the starting point for any code-minimum window performance here.
ENERGY STAR places Nassau County in its North-Central zone for window certification.
Normal temperatures run 32°F in January and 75°F in July, so the glass package worth paying for in Bethpage isn't the same one that pencils out two zones over.

10 top-rated window replacement companies in and near Bethpage
Ranked by Google rating weighted against how many people left one, so a perfect score from a handful of reviewers never outranks a strong average built on hundreds. That ranking is not a license check; call the state directly and ask for the contractor's license or registration number.

Questions to ask before you sign
- How long have you held your state license, and can I see the number?
- Is this a full-frame replacement or an insert into my existing frame, and why that one?
- Who pulls the permit, and does this change trigger an egress check on a bedroom window?
- What flashing and sill pan will you use, and in what order do you install them?
- If my home was built before 1978, is your crew lead-safe certified for this job?
- What's the completion date in writing, and what happens if the schedule slips?
