ECO Window Systems Door Replacement in San Antonio: What to Know First

Independent ECO Window Systems door replacement in San Antonio typically runs $1,850 to $5,400 per opening depending on the door type, glass package, and frame condition. Most jobs are completed in one day once the new unit arrives, usually within two to three weeks of your written quote. We give you a fixed, line-item price before any work starts, so the number on your signed quote is the number on your final invoice, no change orders, no last-minute surprises.

This page is for homeowners in San Antonio, Terrell Hills, Alamo Heights, and surrounding neighborhoods who already have ECO Window Systems products and are dealing with a failed door unit, fogged glass, a frame that’s sagging, or a lock that won’t bite. If you’re in that spot, call us at (903) 488-7019 and we’ll get one of our ECO-savvy technicians out to look at it.

How ECO Window Systems Products Fail – and How We Fix Them

  • Sliding patio door rollers that grind and chew the track (ECO Series 5000 and 6000 sliders). The factory roller assemblies on these units use a plastic housing that San Antonio’s heat eventually makes brittle. We see it constantly in homes west of I-10, where afternoon sun beats on the track. The door doesn’t glide, it drags, and the bottom rail starts wearing unevenly. Our fix is to replace the rollers with machined stainless steel aftermarket assemblies and rebuild the bottom rail sweep so the load distributes evenly across the track, instead of wearing one side down to the aluminum.
  • Fogged insulated glass units in swing patio doors (ECO Series 4000 French door lites and 7000 terrace doors). San Antonio’s humidity, combined with the daily temperature swing, puts a beating on the perimeter seal of older ECO insulated glass. Once the desiccant inside the spacer gets saturated, you get moisture that never burns off. You can wipe the outside all day; the fog is trapped inside. That’s a sealed unit failure. We order replacement IGUs matched to the original glass dimensions and low-E coating, and we re-glaze the sash so the new unit seats properly in the old frame.
  • Multi-point lock mechanisms that bind or stop throwing (ECO Series 7000 entry doors). This one taught us something. The multi-point lock on these doors is a nice piece of hardware, but it relies on the door slab staying perfectly aligned in the frame. San Antonio’s clay-heavy soil means foundation movement is a fact of life, and once the slab shifts even a quarter inch, the strike points on the frame no longer line up with the locking pins. You’ll hear the gear turn but only one point actually engages. We don’t just muscle the hinges; we square the slab, shim to the new reveal, and replace worn gearboxes with exact-spec components so all five points throw with one smooth turn.
  • Weatherstripping and compression seals that turn to dust (all ECO swing door lines). ECO’s early weatherstripping was a foam-backed vinyl that breaks down fast under UV and heat. After five or six San Antonio summers, you’ve got daylight at the sill and a door that rattles in the wind. We strip out the old material and install dual-durometer EPDM bulb seals and a new threshold cap sized to the original ECO extrusion. It quiets the door and stops the conditioned air from leaking into the yard.
  • Frame rot and water intrusion at the rough opening (ECO Series 2000 garden doors and older builder-grade sliders). This is the one we hate finding because it’s almost always from a bad original install, not a bad product. The builder didn’t flash the rough opening correctly, or the pan sat too low, and water wicked into the wood buck. By the time you see dark stains at the interior corners, the frame’s structural integrity is gone. If the foam-filled vinyl frame itself is intact, we can salvage it, rebuild the rough opening, and re-install with full flashing tape, sill pan, and backer rod. If the frame is compromised, it’s replacement time.

Our ECO Window Systems Door Replacement Process

  1. 1
    You call or book online. A live person answers, day or night. We collect the basics: door type, what it’s doing, how old the unit is, and your San Antonio ZIP code.
  2. 2
    We come out and diagnose. One of our technicians measures the door, checks the plumb and level of the existing frame, inspects the hardware, and figures out whether we’re repairing or replacing. If Sean Mackey’s on the job, he’ll walk you through what he’s seeing as he sees it, including anything that might become a problem down the road.
  3. 3
    You get a written quote. Line by line. Door unit, hardware, flashing, trim, haul-off, everything. If the numbers don’t make sense on paper, they won’t make sense on your wall either. We lock that number in before you sign anything.
  4. 4
    We order or pull the parts. For factory-match components, we go OEM when it matters most: glass units, multi-point gearboxes, and finish hardware. For wear parts like rollers and weatherstripping, we’ll recommend a quality aftermarket option that often outperforms the original.
  5. 5
    We install, test, and walk you through. We set the new door, check reveal margins on all four sides, run the full cycle test (open, close, lock, unlock) at least six times, and verify the threshold seals. Then we show you what we did and clean up everything, including the old door.
  6. 6
    It’s covered, in writing. Every completed installation carries our 365-Day Done Right Promise. If the work isn’t right, we make it right, parts and labor, for a full year.

What moves the price: glass package (standard low-E versus impact-rated, which adds real cost but buys real protection), whether the existing frame can be saved, and whether the rough opening needs structural repair. Every quote is free. Call (903) 488-7019 and we’ll give you an exact number for your door, in writing, before anything starts.
