ECO Window Systems window installation in Fort Worth typically runs between $650 and $1,450 per opening when we handle the full replacement, including the window unit, installation labor, and haul-away of the old frame. Most homes we serve in Fort Worth need between five and twelve windows replaced, which puts a full-home project somewhere in the $4,000 to $14,000 range depending on glass package and trim scope.
You’re probably here because an ECO window has started to fog between the panes, stick when you open it, or let a draft through that you can feel from across the room. That’s how most Fort Worth homeowners discover a window has reached the end of its working life. The good news is that ECO Window Systems builds a straightforward frame-and-sash assembly, which means a skilled crew can usually swap a unit in under two hours per opening without tearing into your drywall or exterior siding.
Key takeaways:
- We stock ECO Window Systems-compatible hardware and can source exact OEM replacement units for most models.
- Written price before any work starts, every time.
- The 365-Day Done Right Promise covers the install from day one.
Which ECO Window Systems Models This Applies To
ECO Window Systems produces a focused lineup of vinyl and aluminum window lines built primarily for the Texas and Gulf Coast climate. The three series we see most often in Fort Worth homes are the ECO 3000 single-hung, the ECO 4000 horizontal slider, and the ECO 5000 picture-window series. Each series uses slightly different sash profiles and weather-seal channels, so matching the right replacement part is not a guess-and-check exercise.
The most reliable way to identify your ECO window is to look at the spacer bar between the two panes of glass. ECO stamps their series number there in laser-etched text, usually reading “ECO 3000” or “ECO 4000” along with a manufacturing date code. If the spacer is too fogged to read, measure the visible glass width and the overall frame width. The 3000 series runs a 2 5/8-inch frame depth, while the 4000 slider uses a 3 1/4-inch frame. That 5/8-inch difference matters because the replacement sash and balance hardware are not interchangeable between those two lines.
For OEM versus aftermarket: ECO’s weatherstripping and cam locks are specific enough that we recommend OEM replacements for those. For balance springs and tilt latches, quality aftermarket equivalents from Caldwell and Amesbury hold up just as well at roughly 30 percent less cost. We carry both options on the truck and will show you the difference before we install anything.
We’re an independent Fort Worth installer, not a division of ECO Window Systems, which means we recommend the right fix for the home rather than the fix that moves a particular brand’s inventory this quarter.

Signs Your ECO Window Systems Window Installation Is Failing
- Condensation or fog between the panes. The seal around the insulated glass unit has failed, letting moisture into the space between the two panes. Once that happens, the argon gas that gave the window its insulating value is gone, and the glass is now doing the job of a single pane. This is the most common call we get in Fort Worth during humid summer months, when the temperature difference between inside and out pushes the seal past its limit.
- A sash that drops or won’t stay up. The constant-force balance springs inside the side jambs have lost tension or snapped. Fort Worth’s heat accelerates metal fatigue in these parts, particularly on the sun-facing south and west sides of a house. When one side fails, the sash will feel heavy and uneven.
- You can hear street noise more than you used to. The perimeter weatherstripping has compressed past the point of sealing, and the frame may have shifted slightly out of square. This is common on Fort Worth’s clay-heavy soil, which expands and contracts with rain and drought cycles and can pull a frame out of alignment over a decade.
- Drafts near the meeting rail or corners. This usually means the interlocking weather seal at the check rail has worn through, or the corner keys have relaxed enough that the sash no longer compresses into the seal. You’ll feel it first in a north wind coming off Eagle Mountain Lake.
- The crank or slider feels gritty or binds. On sliders, the track rollers were not designed to handle the fine grit that blows across Fort Worth’s clay and limestone soils. Once that dust works into the roller bearings, the window starts to scrape rather than glide.

AfterReplacement Cost & What’s Included
For ECO Window Systems-specific work in Fort Worth, here is what we quote most often:
- Single-hung window replacement (installed): $650 – $1,050 per opening
- Horizontal slider replacement (installed): $750 – $1,200 per opening
- Picture window replacement (installed): $800 – $1,450 per opening
- Glass-only replacement (same frame, new IGU): $280 – $520 per sash
- Balance spring and hardware replacement (per window): $95 – $210
What drives the spread: glass package (standard dual-pane with argon versus Low-E with a warm-edge spacer versus impact-rated for the occasional Fort Worth hailstorm), frame size, accessibility from the outside, and whether the existing trim can be reused or needs to be reworked. Every quote includes the window unit, all mounting hardware, exterior re-sealing, interior trim touch-up, haul-away of the old window, and a written line-item price before the crew unloads a single tool.
We use pet-safe caulks and sealants where an alternative exists, and the crew drops cloths before anything comes out of the truck. The 365-Day Done Right Promise covers the install workmanship, so if a seal fails or a sash binds within the first year, we come back and make it right without a negotiation.
DIY or Call Us?
There are things you can safely check on your own. You can look at the spacer bar for your series number, test each window for drafts on a cool morning, and note which side of the house is worst-hit by Texas sun. You do not need a technician for that.
What we would not recommend is pulling the sash yourself on an ECO 4000 slider or 3000 single-hung if you have not done it before. The constant-force springs carry enough tension to injure a finger or hand if they release unexpectedly, and the glass unit itself weighs anywhere from 18 to 45 pounds depending on size. Keith Yamada has spent decades doing this work across North Texas, including older bungalows near the TCU campus where trim is brittle and a mis-set sash can split original casing. If you are unsure, call us at (682) 900-6694 first. A site evaluation is free, and we would rather spend twenty minutes confirming what you need than have you lose an afternoon, or a fingertip, to a spring that let go.
A window should bring in light without letting in doubt about how well it was installed.
FAQs
You can expect 18 to 25 years of useful life from most ECO Window Systems frames in Fort Worth before the seals or hardware begin to fail, with the sun-facing south and west elevations aging fastest. The insulated glass seal is typically the first component to go, usually between year 12 and year 18. Call (682) 900-6694 and we will assess what can be saved.
Yes, many failures are repairable, including balance spring replacement, weatherstrip replacement, and glass-only IGU swap-out when the frame is still square and intact. Full replacement is the better call when the frame has warped, the corner welds have begun to separate, or the window is older than 20 years. We will give you an honest recommendation and a written price for both options.
Most single-hung and slider replacements take 45 to 90 minutes per opening once the crew begins, with a full day of work typically covering six to eight windows in Fort Worth. Trim rework or unusual frame depths can add time, and we will tell you that up front before scheduling.
We stock the most-failed ECO components, including constant-force balances, tilt latches, cam locks, and weatherstripping for the 3000 and 4000 series, in our Fort Worth trucks. Glass units and complete replacement sashes are ordered per job to match your spacer-bar markings and arrive typically within one to two weeks. We also carry compatible parts for PGT, CGI, and CWS when a mixed-window home needs attention.
