Short answer
Replacement windows cost about $700 to $2,200 per window installed in our market, and that per-window figure covers the unit, the labor, the sealing and the trim work, not just the window itself. Most whole-house projects land in the middle of the range, with easy standard openings near the bottom and large custom shapes, upgraded frames or openings needing repair near the top. You get one itemized number at a free in-home estimate, because the count and condition of your openings decide the total.
Replacement windows cost about $700 to $2,200 per window installed across our service area in Tennessee, North Georgia and Northeast Alabama. That number is the complete number for one opening — the window, the labor, the sealing, the trim and the cleanup — not a product price you later add installation to.
The reason the range is so wide is that "a window" is not one thing. A standard 3-by-5 double-hung in a sound frame and a 7-foot picture unit over a stairwell are both one window on a count sheet and nowhere near the same price on a quote. Below is what moves a specific opening up or down inside that range, and how the per-window figure turns into a whole-house total.
What does "installed" actually include?
When we quote replacement windows, the per-opening price covers the full sequence of work, not just the unit:
- The window itself — frame, sash, hardware, screen and the glass package specified for that elevation.
- Removing the old unit and hauling it away.
- Setting, shimming and squaring the new window in the opening so it operates correctly for its whole life.
- Insulating and air-sealing the perimeter — the part nobody sees and the part that decides whether the window performs the way its label says it will.
- Exterior sealing and trim, including capping or wrapping where the detail calls for it.
- Interior finish work — stops, jamb extensions or casing depending on the install method.
- Cleanup and a final walk-through with you before the crew leaves.
That matters when you compare quotes. A number that looks lower is sometimes lower because trim work, disposal or interior finish sits outside it as an extra. Ask what the price includes before you compare totals.
Why is the per-window range so wide?
Seven things move the price of a single opening, and most quotes are decided by two or three of them.
| Cost driver | Effect on price | Why |
|---|---|---|
| Size of the opening | High | Bigger glass costs more and takes more hands to set |
| Style and shape | High | Double-hung and slider are the value styles; casement, bay, arched and Palladian cost more |
| Frame material | High | Vinyl is the value answer; composite and fiberglass run more per window |
| Glass package | Moderate | Low-E coating, argon fill and warm-edge spacer are worth the money here |
| Insert vs full-frame | Moderate to high | Full-frame adds several hundred dollars per opening |
| Access | Moderate | Second-story, over-roof and steep-grade openings take longer |
| Condition on tear-out | Varies | Rotted sills or out-of-square frames need repair before the new unit goes in |
What lands at the bottom of the range
Standard-size double-hung vinyl units, in frames that are sound and square, on a first floor with easy access, installed as inserts. If most of your house looks like that, your average per-window number sits in the lower part of the range.
What lands at the top
Large picture units and wide sliders, custom or arched shapes, fiberglass or composite frames, dark exterior frame colors, and any opening where the old aluminum or wood frame has to come out entirely down to the rough opening.
Most houses are a mix. It is normal and correct for one itemized quote to carry three different per-window prices across the same home.
How does that turn into a whole-house total?
Straight arithmetic on the published range, before any repair scope:
| Openings | At the low end | At the high end |
|---|---|---|
| 8 windows | about $5,600 | about $17,600 |
| 12 windows | about $8,400 | about $26,400 |
| 15 windows | about $10,500 | about $33,000 |
| 20 windows | about $14,000 | about $44,000 |
Those outer columns are the extremes, not the likely outcome. Real projects land between them because a house is a mix of easy and hard openings, and because most homeowners choose vinyl for the majority of the house and spend the difference on the glass rather than upgrading every frame.
Does the glass package change the price much?
Less than most homeowners expect, and it is the upgrade that pays back the most here. Our entire service area sits in the ENERGY STAR South-Central climate zone, where a qualifying window needs a U-factor of 0.28 or lower and an SHGC of 0.23 or lower.
SHGC — how much solar heat passes through the glass — is the number that matters most in this market, because our load is cooling, not heating. A west-facing living room that is unusable in July is a solar heat gain problem, and the fix is the coating on the glass. That is why we spec glass by elevation instead of putting the same unit on all four sides of a house.
Triple-pane is available on request but we do not recommend it as a default here. Its returns are strongest in heating-dominated northern climates. In this zone, the same money spent on a better low-E coating, argon fill and a warm-edge spacer returns more.
Why do two quotes for the same house differ by thousands?
Usually for one of four reasons, and none of them is that one company found a magic discount.
- Insert versus full-frame. A quote that assumes inserts everywhere will always be cheaper than one that prices full-frame where the frames are actually rotted. Ask which method is quoted per opening.
- Different product tiers. "Vinyl double-hung" spans a wide quality range. Get the exact product line in writing.
- What the warranty covers. A lifetime warranty on material paired with a one-year labor warranty is a much weaker promise than it sounds. Our windows carry lifetime material and labor coverage under The Patriot's Promise, transferable once and prorated after that.
- What happens when the crew finds rot. A quote that says nothing about it is a quote with a change order waiting inside it. Ask how repair scope gets priced before work starts.
Does the labor rate change with the season?
No. Crews here work one opening at a time year-round, so a house is never open to the weather, and the install quality does not change with the calendar. What changes is scheduling — spring and early summer are the busiest stretch with the longest wait from signing to install, and late fall through winter is usually the fastest to get on a schedule. Price is driven by the openings, not the month.
Installation itself runs one to two days for a typical whole-house job, with each opening taking 30 to 60 minutes as an insert or two to four hours full-frame. The longer clock is manufacturing, because replacement windows are built to your measurements rather than pulled off a shelf.
How do most homeowners pay for it?
Some pay outright. Many use financing through the GreenSky program, which includes no-interest options if paid in full within 6, 15 or 18 months, and fixed-rate terms starting at 6.99% APR for 60 months and running as long as 144 months. Zero down is available for most approved homeowners, subject to credit approval.
One budgeting note worth repeating: there is no federal tax credit for windows placed in service in 2026. The 25C credit was terminated for property placed in service after December 31, 2025. Anyone still building a 30% federal credit into your window budget is working from outdated information.
If phasing makes more sense than doing everything at once, that is a legitimate plan. Do the worst elevation first — usually the west or south side, or wherever the fogged and stuck units are — and come back for the rest later.
What is the next step?
A real number requires someone measuring your actual openings and looking at your actual frames. At a free in-home estimate, the estimator measures every opening, shows you the product, and gives you one itemized price with the install method and glass package spelled out per window. There is no trip charge anywhere in our service area across Tennessee, Georgia and Alabama.
