New Jersey has over 3.5 million housing units — most built before 1990 with single-pane windows that lose 2–4x more heat than modern double-pane glass.
The average New Jersey homeowner spends $350–$750 per window installed. Whole-house replacement (12–20 windows) typically runs $5,000–$14,000.. Costs vary based on window count, frame material (vinyl, fiberglass, wood, aluminum), glass package (double-pane vs. triple-pane, Low-E coating, gas fill), and installation complexity. Getting at least 3 quotes is the best way to ensure competitive pricing.
PSE&G and JCP&L offer up to $75–$100 per ENERGY STAR window installed through the NJ Home Performance with Energy Star program.
NJ winters drop to single digits; triple-pane windows with low U-factor (≤0.27) dramatically cut heating costs.

$350–$750 per window installed. Whole-house replacement (12–20 windows) typically runs $5,000–$14,000.. The final price depends on the number of windows, frame material, glass package, and whether full-frame or insert replacement is needed. Getting multiple quotes is the best way to find fair pricing in your market.
PSE&G and JCP&L offer up to $75–$100 per ENERGY STAR window installed through the NJ Home Performance with Energy Star program.
Most window replacement projects take 1–3 days for a typical home (8–15 windows). Insert replacements (reusing existing frames) are faster than full-frame replacements.
Double-hung replacement is the most popular choice in New Jersey. Vinyl is low-maintenance and cost-effective. Fiberglass is more durable but costs 20–30% more. Wood offers the best aesthetics but requires painting or staining every few years.
Permit requirements vary by municipality. In-kind replacements (same size, same location) often don't require a permit, but structural changes always do. Your licensed contractor should pull all required permits — be cautious of contractors who suggest skipping this step.
