ECO Window Systems Custom & Geometric Windows in Miami: What to Know First
We install, replace, and repair ECO Window Systems custom and geometric windows throughout Miami, and most jobs are finished in a single visit once the glass and hardware arrive. Typical custom and geometric work runs between $1,400 and $4,800 per opening, depending on size, shape, glass spec, and whether the opening needs structural reinforcement for hurricane wind loads. You’ll get the exact number on paper before anything gets ordered.

This page is for homeowners in Miami who already own ECO Window Systems windows, or are weighing them for a custom job, and need a company that understands how these particular frames behave in South Florida heat, salt air, and code-driven wind zones. Call (561) 489-4036 and you’ll get a live person, not a voicemail tree.
How ECO Window Systems Products Fail - and How We Fix Them
- Geometric glazing bead shrink on the Series 900 casement line. On radius-top and trapezoid units, the interior glazing bead is milled tight from the factory. Five to seven years of Miami humidity cycles will pull it enough to let condensation sit against the laminate. We re-seat the bead with an isolation shim and replace the long-axis seal, and it stops. ECO’s own documentation won’t tell you the bead needs a shim; we’ve just done enough of these to know it does.
- Stress fractures at the corner welds on arched window cladding. Arched and eyebrow units put more tension on the welded corners than standard rectangular frames. When the opening settles even a quarter inch, the weld at the crown carries it. That shows up as a hairline crack in the interior finish, not the glass. We pull the unit, re-bed the frame, and have the weld re-done at a metal shop in Hialeah that we’ve used for eleven years.
- Butt-glaze seal failure in long horizontal geometric runs. The Series 750 fixed window line is popular in Miami mid-century homes that run a full wall of glazing with trapezoid or parallelogram transoms above. The butt-glazed seams between units rely on a structural silicone joint that breaks down under constant UV and salt exposure, typically within eight to ten years. We recaulk with a marine-grade neutral-cure silicone and re-bed the gaskets at the joints. The failure mode is predictable, and the repair is durable.
- Track sag on oversized custom sliders. ECO builds a solid slider, but any aluminum track spanning more than ten feet will deflect over time, especially in older Miami homes where the concrete slab has shifted. The door starts to bind at the center, and homeowners assume the bearings are shot. We level the track with stainless shims, re-set the rollers, and the panel glides. Most companies replace the whole door. We’d rather fix what’s fixable and tell you straight when it’s not.
- Weep system clogging on impact-rated geometric units. ECO impact windows drain through a weep channel at the sill. In Miami, wind-driven rain carries fine grit and pollen into those channels, and once they plug, water pools against the lower frame at the corner of the glass. On a trapezoid or triangle unit, that corner is a stress point. We clear the weeps, flush the channels, and verify drainage before we put the interior trim back on. The fix takes an hour. Ignoring it turns a clean window into a rot problem.
Our ECO Window Systems Custom & Geometric Windows Process
Every job runs through the same sequence, because custom windows are only as good as the measurements and the paperwork behind them.
- 1
Call and diagnosis. You call (561) 489-4036, a live person answers, and we schedule the site visit. We measure every rough opening twice, as Dale Kessler puts it: “Measure twice, order once, and put everything in writing.”
- 2
Written quote, side by side. We put the OEM ECO price and any quality aftermarket alternative on paper in front of you, line by line. You see exactly what you’re buying and what it costs.
- 3
Order and lead time. Custom geometric glass has real lead times. Dale will tell you four weeks if the glass house needs four weeks, not four days because it sounds better.
- 4
Installation. Background-checked, uniformed technicians set the unit, flash it for Miami wind-driven rain, and square it to the opening. If the pane is not true, the job is not done.
- 5
Testing and cleanup. We cycle every vent, check drainage on every unit, and pull the interior and exterior trim tight. The area is broom-clean before the truck leaves.
- 6
Warranty registration. Before we leave the driveway, both warranty layers are registered in writing under The Keystone Standard. Durations stated, no fine print that covers neither.
What ECO Window Systems Custom & Geometric Windows Costs in Miami
Most custom and geometric window work in Miami falls into predictable ranges. Here’s what we see on actual jobs:
- Radius-top or arched ECO replacement, impact-rated: $1,600 to $2,900 per opening.
- Custom trapezoid or parallelogram fixed window, 20 to 35 square feet: $2,200 to $4,200 installed.
- Oversized geometric slider with reinforced track: $3,300 to $5,800 depending on glass package and frame reinforcement.
- Full-wall glazing replacement with geometric transoms: $8,500 and up, quoted by the linear foot after the site visit.
The biggest variables are size, shape complexity, impact rating, and whether the existing rough opening needs any structural work. Cheaper bids usually cut the glass spec or skip the flashing detail. Ours doesn’t. Call (561) 489-4036 for a free estimate, and you’ll know the real number before you spend a dollar.
Why Miami Homeowners Call TruePane Windows & Doors for ECO Window Systems Work
We’re an independent ECO Window Systems service provider, not a franchise truck with a brand sticker. That means we can put OEM and quality aftermarket parts side by side on paper and let you decide. It also means we handle the other lines in your house: PGT, CGI, CWS, and ES Windows all cross our trucks in a given month.

Every job carries the 90-Day Done Right Promise. If it’s not done right, we make it right, with no paperwork fights and no arguing. That’s the same standard Dale Kessler’s father worked under in Columbus, and it’s the same one our crews hold to in Miami coast neighborhoods where salt air punishes corners and flashing. We’ve been doing this work in South Florida long enough that our reputation matters more than any single sale. Live person on the phone, 24 hours a day. Background-checked, uniformed technicians. And a written warranty before the truck leaves the driveway. We stand behind it.
FAQs
Yes, in most cases. ECO has shifted lineups over the years, and discontinued series like the older 500 fixed units can’t always be ordered OEM. We match the glass spec, frame profile, and finish from aftermarket manufacturers in South Florida, and we’ll tell you upfront if the match is close or exact. Call (561) 489-4036 for a straight answer.
No. Replacing one window does not void the warranty on surrounding units, as long as the replacement is installed to code with proper flashing. We document every install that touches an ECO frame so you have a paper trail if you ever need it.
Most orders run three to seven weeks, depending on the glass house and whether the opening is impact-rated. Custom shapes with laminated glass and argon take longer. Dale will give you the lead time when we quote, and we don’t pad it.
It depends on the frame condition. If the corners are sound and only the seal or glazing bead has failed, repair is half the cost of replacement and done in one visit. If the frame is corroded at the welds, replacing the unit is the honest call. We’ll tell you which one you’re in and put the numbers on paper.
