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.
Double-hung sashes ride on either block-and-tackle, spiral, or constant-force balances. Cheap units use block-and-tackle that stretches; constant-force balances cost $40-80 more per window but hold position for decades.
Tilt-in sashes let you clean both sides from inside. That matters immediately at install (no exterior ladder work) and again every time glass needs cleaning, which is the number one reason people regret buying non-tilt units.
Two double-hung units at the same price can differ by a factor of three on air infiltration (AL rating). On a windy exposure that difference is visible as draft and audible as whistle.
Double-hung costs $60-150 more per window than single-hung but allows cleaning both sashes from inside and provides full top ventilation. Single-hung is the better value on fixed-budget whole-house projects where upper sashes will rarely be opened.
Vinyl double-hung units typically last 20-25 years. The first failures are usually seal failure in the glass unit (fogging) rather than the frame or balances.
Sash replacement kits exist for some brands and cost roughly 40-60% of a full unit. They only work if the frame and balances are still sound, which is uncommon past 15 years.
