ES Windows Custom & Geometric Windows in Boca Raton: What to Know First
We install, repair, and replace ES Windows custom and geometric windows across Boca Raton, and most jobs are quoted within 48 hours and completed in one to three weeks once the glass is ready. Custom shapes cost more than standard rectangles - that’s just geometry and glass fabrication, not a markup game - but we price the work line by line so you see exactly where the money goes. If you own an ES Windows arched, radius, trapezoid, or oversized unit in Boca Raton and it’s fogged, leaking, or just tired, call (561) 816-5648 and we’ll tell you straight what it needs and what it’ll cost.
How ES Windows Products Fail - and How We Fix Them
ES Windows builds a solid aluminum frame, but Boca Raton’s salt air, afternoon thunderstorms, and UV load expose weak points that show up first on non-rectangular units. Here’s what we actually see on service calls:
- Arched and radius units losing their seal at the apex. On ES Windows’ curved-top models, the glass-to-frame bond at the highest point of the arc takes the most thermal expansion stress. When the seal lets go, you get condensation between the panes that never dries. We reglaze the unit with fresh structural silicone and, where the frame shows corrosion pitting, treat and reseal the aluminum before the new glass goes in.
- Trapezoid and triangle windows with bowed frames from settling. Boca Raton sits on a mix of sand and muck, and homes in neighborhoods like Boca Square and Hidden Valley shift more than owners expect. A geometric ES Windows unit is more rigid than a standard rectangle, so when the opening moves, the frame takes the strain instead of flexing. We’ve fixed more than a few triangle windows where the frame was actually holding up the corner of the opening. The fix is re-squaring the rough opening, not just shimming the window.
- Gear hinge wear on ES Windows impact casements in custom sizes. The ES Windows impact casement line uses a multi-point lock and heavy stainless hinges. On oversized or heavy custom casements, those hinge gears wear unevenly, and the sash starts to sag a quarter inch at the latch corner. You’ll feel it when you close the window - it catches, then drops. We replace the hinge set with the correct weight rating for the sash, not a generic one-size-fits-all part.
- Weep system clogging on ES Windows horizontal sliders with geometric glass packages. Custom glass often means deeper frame pockets to hold laminated or double-glazed units, and those pockets collect sand and salt residue faster on ES sliders than most people realize. If you see water pooling inside the track after a Boca Raton downpour, the weeps are blocked. We clear the channels, check the drainage slope, and reseal the exterior flange so water has somewhere to go besides your drywall.
- Stress cracks at sharp corners on geometric units. A true geometric window - a triangle, a parallelogram, a pentagon - has glass cut at angles that create stress concentration points. ES Windows’ laminated impact glass is tough, but a hard enough impact near those corners and you’ll see a crack spider out from the sharpest angle. That’s not a defect, it’s physics, and the fix is a new fabricated insulated glass unit cut to the exact template, which we order through our glass fabricator to match the original spacing and tint.
Our ES Windows Custom & Geometric Windows Process
When you call us about an ES Windows unit in Boca Raton, here’s what happens, in order:
- 1
You call (561) 816-5648. A real person answers. You describe what the window’s doing, we ask a few questions about the shape, size, and symptoms, and we schedule the on-site visit.
- 2
We measure and diagnose. Ed Winslow or one of our senior techs comes out, takes precise measurements of the opening and the existing unit, and figures out whether the problem is the glass, the frame, the hardware, or a combination. We’ll tell you what we find in plain English while we’re standing there.
- 3
We make the parts call. For ES Windows units, we look at what’s still under the original warranty first. If the part’s covered, we’ll help you through the claim. If it’s not, we talk honestly about OEM versus a quality aftermarket equivalent - sometimes the OEM part is the only smart choice, sometimes a domestic alternative does the same job for less. You decide, we just give you the real numbers.
- 4
We do the work. Custom glass gets templated and fabricated to match your unit exactly. Installation day, we protect the work area, pull the old unit, prep the opening, set the new one, and seal it like it needs to survive a hurricane - because it does.
- 5
We test everything. We cycle the window, check the seals, run water over the exterior, and make sure the operation is smooth. If anything’s off, we fix it before we leave.
- 6
We walk you through it. You see the finished window, we show you what we did and why, and we leave the job site clean. Then the 36500-Day Done Right Promise kicks in - if it’s not done right, we come back and make it right.
What ES Windows Custom & Geometric Windows Costs in Boca Raton
Straight numbers, no mystery. Here’s what ES Windows custom and geometric work typically runs in Boca Raton:
- Resealing an arched or radius ES Windows unit: $400-$800, depending on size and frame condition.
- Replacing a fogged insulated glass unit in a trapezoid or triangle: $600-$1,400, driven by glass size and whether it’s laminated impact-rated.
- Full replacement of a standard-sized custom ES Windows window: $1,200-$3,500, depending on impact rating, glass package, and installation complexity.
- Full replacement of an oversized geometric ES Windows unit: $3,500-$8,000+, shaped by the opening size, engineering requirements, and whether the frame needs structural work.
What moves the price: the size of the glass, whether it’s impact-rated (most Boca Raton homes need it), how accessible the opening is, and whether the existing frame can be salvaged. We give you a written, line-item quote before any work starts, and the price doesn’t change unless you change the scope. Call (561) 816-5648 to schedule a free estimate.
Why Boca Raton Homeowners Call Winslow Windows & Doors for ES Windows Work

We’re also an authorized installer for PGT, CGI, CWS, ECO Window Systems, and four other premium brands, so if an ES Windows unit has reached the end of its life, we can talk honestly about whether a different brand makes more sense for your next window. Every tech who shows up is background-checked and in uniform. Every call is answered by a live person, 24/7. And Ed’s name is on the door - and on every job we do. As he puts it: my name’s on the truck, so the work has to be right.
FAQs
Yes, in most cases we can source the parts through our supplier network or fabricate a correct-fit replacement. Some very old ES Windows hardware is no longer made, and when that happens we’ll tell you honestly and show you an equivalent option that fits and functions properly. Call (561) 816-5648 and we’ll identify your unit and check availability.
No, not when the repair is done correctly with appropriate materials. We’re careful to preserve your warranty position - we document the work, use compatible parts and sealants, and never do something that would give the manufacturer a legitimate reason to deny a claim. If your unit is still under warranty, we’ll help you file the claim before touching anything.
If the frame is square, not corroded, and the hardware is functional, replacing the insulated glass unit is usually the smarter money - it costs less than a full replacement and restores the window for years. If the frame is bowed, pitted from salt corrosion, or the hardware is failing, full replacement is the honest recommendation. We’ll show you the condition and let you decide.
Most custom ES Windows replacements in Boca Raton take one to three weeks from order to installation, depending on glass fabrication time and whether the unit is impact-rated. We confirm the timeline in your written estimate.
Yes. We pull the permit, coordinate the inspection, and stand behind the work. If the city of Boca Raton requires engineering for an oversized opening, we handle that too. Call (561) 816-5648 for a free estimate and we’ll walk you through the whole process.
