Most homeowners in the Triangle area spend between $600 and $1,300 per window installed, based on real project data from across North Carolina. The national average sits around $1,047 per window when you factor in both materials and labor.
Your actual number will depend on what kind of windows you have, what you’re replacing them with, and the condition of your existing frames.
Here’s a straightforward breakdown.
Quick Cost Reference by Window Type
| Window Type | Installed Cost (per window) |
|---|---|
| Single-hung (vinyl) | $300 – $600 |
| Double-hung (vinyl) | $400 – $800 |
| Casement | $500 – $1,100 |
| Sliding | $450 – $900 |
| Bay or bow | $1,200 – $3,500+ |
| Specialty / custom shape | $1,000 – $2,500+ |
For a standard home with 10 to 15 windows, total project costs typically fall between $7,000 and $15,000. Replacing all your windows at once almost always gets you a better per-window price than scheduling them one at a time.
What Drives the Price Up (or Down)
Frame Material
Vinyl is the most popular choice for good reason: it holds up well in humid climates, requires almost no maintenance, and costs less than wood or fiberglass. Wood frames run higher but offer a more traditional look. Fiberglass is the most durable option and comes with the highest price tag.
- Vinyl: most affordable, low maintenance, good insulator
- Wood: mid-to-high range, classic appearance, requires periodic upkeep
- Fiberglass: premium cost, strongest long-term performance
- Aluminum: budget option, conducts heat/cold more than other materials
Insert vs. Full-Frame Replacement
An insert replacement slides a new window into your existing frame. It’s faster and costs 10–15% less than a full-frame job.
Full-frame replacement removes everything down to the rough opening. If your frames are rotted, warped, or water-damaged, which is common in older homes, full-frame is the only real option. Skipping it when the frame is compromised leads to bigger problems later.
Glass Type
Double-pane Low-E glass with argon gas fill is the standard for most new installations. Adding energy-efficient glass upgrades typically adds $50 to $200 per window but lowers monthly utility costs. In North Carolina’s climate, hot, humid summers and cool winters, proper glazing makes a noticeable difference in comfort and on your energy bill.
Window Location
Ground-floor windows are straightforward to install. Second or third-story windows require more setup, additional safety equipment, and more labor time. Expect those to run higher.
What About Labor Costs?
Labor typically runs $100 to $300 per window for a standard installation. In the Triangle, labor rates are generally more competitive than in coastal North Carolina or major metros like Charlotte. Materials typically make up about two-thirds of the total cost, with labor covering the remaining third.
Will New Windows Save You Money?
According to survey data compiled by This Old House, about 67% of homeowners report saving between $25 and $100 per month on energy bills after window replacement. Over 10 years, that adds up.
Vinyl window replacement also returns around 67% of the project cost at resale, and wood windows can return closer to 75% in some markets, based on data from Remodeling Magazine’s Cost vs. Value report.
What to Ask Before You Get a Quote
- Is this an insert replacement or full-frame? (The answer affects both price and performance.)
- Are permits required for this project?
- What’s the window’s U-factor and Solar Heat Gain Coefficient (SHGC)? Lower is better for both in NC.
- Does the quote include caulking, trim work, and cleanup?
- What does the labor warranty cover?
