Ranges reflect installed cost including materials and labor for typical residential work. The low end of each range corresponds to a basic vinyl configuration; the high end reflects premium frames, upgraded glazing, and larger units. Last reviewed 2026-11-12.
New-construction windows include a nailing flange and are installed before siding goes on. Replacement windows are sized to fit inside an existing frame and have no flange. Using the wrong type is a common and expensive mistake.
New windows are ordered by rough opening, not by the visible glass size. Measuring the finished opening instead of the rough opening is the single most common cause of a returned order.
Ordering 10+ units at once moves you into builder pricing tiers. Per-unit cost can drop 12-25% compared with ordering the same windows one at a time.
Installing new-construction windows during a build or addition avoids tear-out and disposal entirely, so the installed cost is lower than retrofitting the same windows afterward.
A nailing flange is a perimeter fin that fastens the window to the wall sheathing and integrates with the weather barrier. You need one for new construction and for full-frame replacement where siding is removed. Insert replacements do not use one.
Vinyl units are typically 2-6 weeks from order to delivery in normal conditions. Custom sizes, non-standard colors, and peak season push that to 8-12 weeks.
