Factors That Affect Window Replacement Cost
Window Size and Style
Standard double-hung windows are the most affordable. Larger windows like picture windows, bay windows, and bow windows cost significantly more — a bay window installation can run $1,500 to $4,000. Specialty shapes like arched or round-top windows also add to the cost due to custom manufacturing.
Glass Options
Double-pane with Low-E coating and argon gas fill is the NJ standard, included in most quotes. Upgrading to triple-pane glass adds $75 to $150 per window but provides superior insulation and noise reduction. Impact-resistant glass for storm protection adds $100 to $200 per window.
Number of Windows
Replacing more windows at once reduces the per-window cost. Most contractors offer volume discounts for whole-home replacements. Doing all windows at once also ensures consistent appearance and eliminates the hassle of multiple project phases.
Installation Complexity
Standard insert replacements (new window into existing frame) are the most affordable. Full-frame replacements that remove the entire old frame and install a new one cost 20 to 30 percent more but are necessary when frames are rotted or damaged. Second and third-floor windows cost more due to ladder and scaffolding requirements.
How Much Can New Windows Save on Energy Bills?
The U.S. Department of Energy estimates that replacing single-pane windows with Energy Star certified double-pane windows saves $125 to $465 per year on heating and cooling. Homes with older double-pane windows that have lost their argon gas seal also see significant savings. In NJ, where we heat for 5 months and cool for 3 months, energy-efficient windows pay for themselves over time through reduced utility bills.
Best Window Brands We Install
Morris Renovations is an authorized dealer and installer for three of the top window brands in the industry.

All three brands offer strong manufacturer warranties when installed by a certified contractor like Morris Renovations.
Window Replacement Tax Credits and Incentives
The federal Energy Efficient Home Improvement Credit allows homeowners to claim up to $600 for qualifying Energy Star certified windows. NJ may also offer state-level incentives through utility companies. These credits can offset 5 to 10 percent of your window replacement cost. We recommend consulting your tax advisor for the latest eligibility requirements.
