What is the average cost of single window replacement in New Brunswick in 2026?

Single window replacement in New Brunswick typically ranges from $400-$1,200 per window installed, depending on the window type, size, and installation complexity. For a standard double-hung vinyl window in good condition rough opening, expect to pay $500-$700 including installation.

Budget breakdown for single window replacement:

• Economy vinyl windows: $400-$600 installed (basic double-hung, standard sizes)


• Mid-range vinyl or aluminum-clad wood: $600-$900 installed (better energy ratings, upgraded hardware)


• Premium wood, fiberglass, or triple-pane: $800-$1,200+ installed (high-performance, custom sizes)

Several factors significantly impact your final cost in New Brunswick. Window size and style make the biggest difference — a standard 30"x48" double-hung costs much less than a large picture window or specialty shape. Installation complexity varies dramatically between a simple replacement in good condition framing versus needing structural repairs, trim work, or dealing with older homes where the rough opening may not be square.

New Brunswick's harsh winters demand quality installation — improper sealing leads to ice damming, condensation, and massive heat loss. Many contractors recommend upgrading to triple-pane windows (especially facing north) given our -25°C to -35°C winter temperatures. The energy savings from a quality window often justify the higher upfront cost, particularly with NB Power's energy efficiency rebates available for qualifying upgrades.

Professional installation is strongly recommended for several reasons. Window replacement affects your home's building envelope and energy performance. Poor installation voids manufacturer warranties and can cause serious moisture problems in our freeze-thaw climate. Most quality window manufacturers require professional installation to honor their 10-20 year warranties.

Getting quotes from multiple contractors in our directory will give you the best sense of local pricing. Ask specifically about warranty coverage, what's included in installation (trim, caulking, cleanup), and whether they're experienced with your home's vintage — older New Brunswick homes often have unique challenges that require skilled handling.

For permit requirements, contact your local building authority. Most single window replacements don't require permits, but check with your municipality or Regional Service Commission if you're in a rural area.
