New windows change how your home looks, feels and performs. This guide covers when to replace, which styles to consider, what drives cost, and how to choose an installer you can trust.
Why Window Replacement Matters
Windows are a big source of heat loss in most older homes. Good replacements cut drafts, quiet the house, make it easier to keep clean, and give your curb appeal an instant lift.
Signs It’s Time to Replace Your Windows
- Drafts or cold spots near windows
- Fog or moisture between the panes
- Sashes that stick, won’t stay open or won’t lock
- Soft, rotting or peeling frames
- Heating and cooling bills that keep rising
Popular Window Styles to Consider
Double-Hung Windows
Two sliding sashes that tilt in for cleaning. They suit almost any home.
Casement Windows
Cranks open wide for airflow and seals tight when closed.
Bay & Bow Windows
Projects outward to add light, space and a window seat.
Picture Windows
A fixed pane for maximum light and an unobstructed view.
Awning Windows
Hinged at the top, so you get ventilation even in light rain.
Hopper Windows
Tilts in from the top. It’s a smart fit for basements and bathrooms.
Sliding Windows
Glides side to side. It’s simple and easy to use.
Specialty Windows
Arches, half-rounds, octagons and custom shapes for a one-of-a-kind look, including over a door.
Understanding Energy Efficiency in New Windows
Look for insulated vinyl frames, double- or triple-pane glass, Low-E coatings and gas fill. Just as important is a careful installation that seals the gap between the window and your wall. Learn more in our energy-efficient windows guide.
What Affects the Cost of Window Replacement
- The number and size of the windows
- The style (bay and bow windows cost more than double-hungs)
- Glass package and options like grilles or colors
- The condition of the existing frames and any repairs needed
- Installation type: insert or full-frame
