Cost & Value
How much do replacement windows cost on Long Island? (2026)
A realistic breakdown of what homeowners in Nassau and Suffolk actually pay for replacement windows, and how factory-direct pricing changes the math.
Quick answer
On Long Island, replacement windows typically run about $600-$1,500 per window installed, or roughly $8,000-$18,000 for a full home of 10-15 windows. Factory-direct pricing from a manufacturer like EcoView lowers that by removing the reseller markup, with financing from $78/mo.
What affects the price of replacement windows
No two Long Island homes are identical, so a few factors drive your total:
- Number of windows, the biggest single factor.
- Window style, double-hung and sliders sit at the lower end; bay, bow and specialty shapes cost more.
- Glass package, Low-E, argon fill and triple-pane or impact glass add performance and cost.
- Installation type, a simple insert costs less than a full-frame replacement that rebuilds the opening.
- Who you buy from, resellers mark manufacturer pricing up two to three times.

How factory-direct lowers the cost
Most companies buy windows from a manufacturer and resell them to you at a markup. EcoView is the manufacturer, so you pay factory-direct pricing and skip the middleman. Combined with 0% financing and a lifetime transferable warranty, that changes the long-term value, not just the sticker price.
