Window replacement cost by style depends on the unit type, frame material, and whether the existing frame can stay in place. Most homeowners should plan on $350–$1,100 per window installed, though specialty styles such as bay or bow windows cost significantly more. These figures are planning estimates, not quotes, because final pricing requires an on-site frame inspection.
At Window Replacement Lab, we price window replacement as separate line items: the unit, labor, removal, and trim. An insert replacement keeps the existing frame, while a full-frame replacement removes the unit down to the rough opening. The right choice is decided after the frame is inspected, not before.
Common Window Styles and Estimated Costs
Style affects price because it changes glass area, frame complexity, hardware, and installation time. Below are estimated installed cost ranges for common residential styles.
| Window style | Estimated installed cost (USD) |
|---|---|
| Single vinyl double-hung, insert | $350–$800 |
| Full-frame replacement, standard size | $550–$1,100 |
| Fiberglass window | $600–$1,200 |
| Wood or composite window | $900–$1,800 |
| Bay or bow window | $1,500–$5,000 |
| Impact or hurricane window | $1,200–$2,600 |
| Glass pane or IGU replacement | $150–$450 |
| Window screen replacement | $100–$350 |
These are national planning bands. Local labor rates, window size, glass options, and trim work can move the final price outside these ranges.
Double-Hung Windows
Double-hung windows are the most common replacement style in the US. Both sashes slide vertically, which makes cleaning and ventilation straightforward. A single vinyl double-hung installed as an insert typically costs $350–$800. If the frame is rotted or out of square, a full-frame replacement is required, moving the estimate to $550–$1,100.
Labor for a standard double-hung insert usually takes one to two hours per window. Full-frame work adds time for frame removal, sill repair, and interior trim. Because pricing splits unit, labor, removal, and trim, a homeowner replacing eight windows might see removal charged per window and trim charged per opening rather than as one bundled figure.

Casement Windows
Casement windows hinge on the side and crank outward. They seal tightly when closed and often suit hard-to-reach places such as above kitchen sinks. Because casement units include operating hardware and crank mechanisms, they can cost more than a comparable double-hung. Installed pricing generally follows the material band: vinyl casement inserts near the lower end of the $350–$800 range, while fiberglass or wood casements move toward $600–$1,800.
Installation requires careful leveling so the sash closes evenly. If the existing frame is not plumb, full-frame replacement is usually the better long-term option.

Sliding Windows
Sliding windows move horizontally on a track and work well in wide, short openings. They have fewer moving parts than casement units, which can simplify installation. Vinyl sliding windows typically price within the standard insert or full-frame bands, while larger sliding units with multiple panels increase glass area and frame cost.
Track condition matters. If the sill or track is damaged, the installer may recommend full-frame replacement rather than an insert.

Picture Windows
Picture windows do not open. They exist to provide light and views, which means they often use larger glass areas than operable windows. Because there is no hardware or operating sash, the unit itself can be less expensive than a comparable casement or double-hung. However, large picture windows may require heavier glass and additional framing support.
Full-frame replacement is common for picture windows when the existing frame cannot support the weight of a larger insulated glass unit.

Bay and Bow Windows
Bay and bow windows are projection styles that extend from the wall and usually combine multiple window units. A bay typically has three panels, while a bow uses four or more to create a curved appearance. Because they involve multiple units, structural framing, roofing or flashing over the projection, and extensive interior and exterior trim, they cost substantially more than flat windows.
Estimated installed cost for a bay or bow window is $1,500–$5,000. The wide range reflects size, number of units, roof complexity, and whether the wall needs structural reinforcement. Labor is often priced per project rather than per window because the units are installed together as one assembly.

Frame Material and Cost
Frame material changes both the unit price and long-term maintenance.
- Vinyl: Low maintenance and typically the most affordable. A single vinyl double-hung insert runs $350–$800.
- Fiberglass: Strong and dimensionally stable. Installed fiberglass windows estimate at $600–$1,200.
- Wood or composite: Higher material cost and more upkeep. Installed wood or composite windows estimate at $900–$1,800.

Impact or hurricane windows use laminated glass and reinforced frames to resist wind-borne debris. Installed estimates run $1,200–$2,600, reflecting the heavier glass and stricter installation requirements in coastal regions.
How the Pricing Is Broken Down
Window Replacement Lab does not present a planning band as a quote. Every estimate separates:
- Unit: the window and glass package.
- Labor: installation time based on style and access.
- Removal: taking out the old window and disposing of debris.
- Trim: interior and exterior finishing around the new frame.
For example, if a homeowner replaces one vinyl double-hung as an insert:
- Unit: within $350–$800 installed planning band
- Labor: added based on local rates and window accessibility
- Removal: charged per window
- Trim: charged per opening if new casing or stool is needed
If the frame inspection reveals rot or water damage, the job converts to full-frame replacement. That moves the base planning band to $550–$1,100 and adds carpentry for the rough opening.
Repairs Versus Full Replacement
Not every issue requires a new window. If the frame is sound but the glass is foggy or broken, glass pane or IGU replacement costs about $150–$450. A damaged screen runs about $100–$350 to replace. These repairs cost less than a full window replacement but do not address frame performance or air leakage.
Getting an Accurate Price
Because insert versus full-frame is decided after the frame is inspected, online figures should be treated as planning estimates only. A site visit allows an installer to check frame condition, measure rough openings, confirm operating clearances, and price unit, labor, removal, and trim separately. Homeowners in hurricane-prone areas should also confirm whether impact-rated units are required by local code.

Frequently asked questions
What affects window replacement cost by style?
Style changes glass area, frame complexity, hardware, and installation time. A standard double-hung costs less than a bay window because it uses fewer materials and less labor.
Is insert replacement cheaper than full-frame?
Yes. An insert fits inside the existing frame and typically runs $350–$800 for a single vinyl double-hung, while full-frame replacement starts around $550–$1,100.
Do bay and bow windows cost more?
Yes. Bay or bow windows range from $1,500–$5,000 because they involve multiple units, structural support, and extensive trim and finishing work.
Can I replace just the glass pane?
Yes. Glass pane or IGU replacement costs about $150–$450, which is less than replacing the entire window unit and frame.
How much is a window screen replacement?
A window screen replacement typically costs $100–$350, depending on size, screen material, and whether the frame needs repair.
Should I get an inspection before pricing?
Yes. Insert versus full-frame is decided after the frame is inspected, and unit, labor, removal, and trim are priced separately.
