AfterTrusted Custom & Geometric Windows for Coral Gables Homeowners
Custom and geometric windows in Coral Gables are exactly what they sound like: windows built to a specific shape, angle, or size that a standard off-the-shelf unit cannot match. Think arches, circles, triangles, octagons, trapezoids, and oversized fixed panes that turn a plain wall into the focal point of the room. Ed Winslow has been designing and installing these windows across Coral Gables since 2011, and every job carries the Done Right Promise: if it’s not done right, we make it right, period.
We’re the local, owner-operated crew that Coral Gables homeowners call when a big-box installer tells them a half-round window “can’t be done” or quotes a number that sounds made up. Impact-rated, energy-certified, and built to Miami-Dade code where required, every custom window we install is backed by Ed’s name on the door and on the job. Call (904) 478-8983 and a live person answers, day or night.
What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Custom impact windows combine the protection of a hurricane-rated laminated glass system with shapes and sizes that stock impact windows rarely cover. We order these as fully engineered units, not field-modified glass, so the impact rating stays intact from the factory test to your Coral Gables opening. Whether you’re replacing a shattered pane in a 1970s octagon window or building a new waterfront room that needs an arched impact unit, we handle the measuring, the permitting paperwork, and the installation as one accountable team.
Geometric & Shaped Windows
Geometric windows include any non-rectangular unit: octagons, hexagons, circles, half-circles, ellipses, and triangles. Coral Gables has a deep inventory of Mediterranean Revival and Spanish Colonial homes where these shapes are part of the architectural identity, and getting the rough opening right matters as much as the glass itself. We template every opening by hand before ordering, so the new unit seats correctly the first time without awkward trim gaps or caulk lines that look like an afterthought. If the old window leaked or fogged, we’ll also identify whether the failure was in the unit or the surrounding flashing before we quote the replacement.
Arched & Curved Windows
Arched windows are the ones that follow a curve at the top, whether it’s a true half-round, an eyebrow arch, or a segmental arch. They show up constantly in Coral Gables entryways, gables, and transom assemblies above doors and standard windows. Winslow Windows & Doors orders these as radius-matched units with matching interior and exterior trim profiles, because a slightly-off radius creates a visible gap that no amount of caulk will fix. We also replace the matching rectangular units below arched transoms when the whole assembly needs to perform as one impact-rated system.
Oversized Openings
Oversized openings are anything beyond standard production-window dimensions, including floor-to-ceiling fixed panes, wide picture windows, and custom mulled assemblies that combine multiple shapes into one opening. These jobs often require heavier glass packages, structural mullions, and a second set of hands on the ladder, which is exactly what our uniformed, background-checked installers are trained for. In Coral Gables, where you may be dealing with older masonry walls, we’ll assess the load path and header before we quote, and we’ll tell you plainly if the opening needs structural work before the window goes in. Upfront pricing, no surprises on the invoice.

Brands We Service for Custom & Geometric Windows
We’re an authorized installer for CGI, and we’ve been working with their impact-rated product lines since our earliest days serving Coral Gables. When a homeowner needs a custom-shaped CGI unit, we handle the factory order, the exact sizing, and the paperwork so the warranty stays intact. Their laminated glass performs exceptionally well in arched and geometric configurations, and we know which of their lines make sense for which Miami-Dade wind zones.
We also service and install ES Windows and ECO Window Systems products, both brands known for slim sightlines and custom-shape capability. ES Windows gives us flexibility with large fixed panes and contemporary opening configurations, while ECO Window Systems is often the best answer for Coral Gables homes that need impact protection inside a historically faithful profile. Whether you have one of these brands already installed or you’re starting from scratch, we can match, measure, and install without the runaround. If your home has Mr-Glass or CWS units, our team can service those as well, because we do not walk away from a window because of the name on the sticker.
Signs You Need Custom & Geometric Windows Right Now
- Visible moisture or fogging between the panes. A failed seal on a geometric or arched unit means the insulated glass assembly has lost its integrity. In Coral Gables humidity, that fog turns into permanent mineral staining inside the glass, and the window loses its energy efficiency. The shaped unit cannot be “repaired” by a standard glass shop; it has to be replaced, and the sooner you catch it the more you save on surrounding trim repair.
- Drafts around a curved or angled window frame. Older custom windows in Coral Gables homes often suffer from failing caulk joints where the drywall, stucco, and frame meet the curved edge of the window. If you feel air movement or see daylight at the perimeter, the opening is losing conditioned air and the window is no longer sealed. This is a fixable problem if caught before rot sets into the framing, but delaying it turns a recaulk into a full-frame replacement.
- Difficulty opening or closing a shaped operable window. Functional geometric windows, like casements with an arched top or triangular awning windows, can bind, sag, or fail at the hinge over time. If you have to lift, shove, or prop the window open, the hardware is failing and the glass is stressing in ways it wasn’t designed to. We’ll tell you honestly whether the repair is worth it or a replacement makes more long-term sense for your Coral Gables home.
- Cracks radiating from the corner of a geometric pane. Non-rectangular glass is more prone to stress cracks concentrated at the sharp corners of the shape. A crack in an octagon or triangle window is typically not a cosmetic issue, it’s a structural failure of the lite, especially if the unit is impact-rated and the lamination has started separating. Any crack in an impact window compromises the entire assembly, and it should be assessed immediately.
- You’re planning a renovation that changes window openings. A room addition, a new gable, or a mid-century modern remodel in Coral Gables often means creating a custom opening that a production window simply won’t fit. Getting our team involved before framing gets locked in saves you thousands in change orders. We’ll provide exact rough-opening dimensions and structural requirements before your contractor builds the wall.
Our Custom & Geometric Windows Process - Step by Step
- 1
Free on-site consultation and measurement. We come to your Coral Gables home, assess the existing opening or the new construction plan, and take exact measurements using a combination of digital laser tools and physical templates for curved or angled shapes. We also look at the structural header, the flashing condition, and the surrounding stucco or siding to identify hidden scope items before you get a number.
- 2
Written, line-item estimate with no hidden costs. You’ll receive a fixed-price estimate that breaks down materials, labor, and any required permitting. Ed Winslow reviews every custom window quote before it goes out, because odd shapes and oversized glass require factory verification before we commit to a number. No vague language, no allowances, no “we’ll see when we get in there” clauses.
- 3
Factory order and lead-time confirmation. Custom and geometric windows are made to order, not pulled from a shelf. We submit the exact specifications to the manufacturer, confirm lead time, and keep you updated if anything shifts. For impact-rated custom units, we also verify the product approval matches your Coral Gables wind zone and structure classification before the order is finalized.
- 4
Careful removal and professional installation. Our background-checked, uniformed crew arrives on the scheduled day, protects your floors and landscaping, and removes the old unit without collateral damage to the surrounding wall. We set the new window, level every axis, and flash it according to Miami-Dade code requirements. For arched and shaped units, we take extra time to ensure the reveal lines are perfectly even.
- 5
Final inspection and cleanup. We walk the job with you, check the operation of every sash and lock, and verify the seal at every perimeter joint. Then we clean up completely, haul away the old window, and register your warranty. If anything isn’t right, you call Ed directly. That’s the Done Right Promise, and it’s been the standard on every Coral Gables custom window job since 2011.
How Much Does Custom & Geometric Windows Cost in Coral Gables?
A typical custom impact window in Coral Gables runs $900 to $2,800 per unit depending on the glass package, size, and whether the window is fixed or operable. A simple stock-size impact window might run $700 to $1,400, but a custom arch or circle adds real money because the glass is cut to a radius, the frame is purpose-built, and the unit is engineered individually for wind load. Geometric shaped windows without impact rating, such as a standard half-round accent unit, typically fall between $500 and $1,800 installed, while oversized architectural openings can run $2,500 to $6,000 or more depending on whether you need structural mullions or additional framing work.
What moves the price: the brand you select, the impact rating, the finish package, the accessibility of the opening, and whether the existing frame needs repair or full replacement. The most common overpay scenario we see is a homeowner paying for a custom unit when the opening would work with a high-quality stock window plus a custom trim kit. We’ll tell you which is which, because Ed’s name is on the door and on every job we do. Call (904) 478-8983 for a free, exact quote, and remember our standing offers: $40 off any repair over $200, a free second opinion on any written estimate you already have, no trip charge inside our home county, and a permanent 10% discount for seniors and veterans.

Frequently Asked Questions - Custom & Geometric Windows in Coral Gables
A custom or geometric window is any window that is not a standard rectangle: arches, circles, octagons, triangles, trapezoids, and oversized fixed panes. In Coral Gables, these windows are common in Mediterranean, Spanish Colonial, and contemporary homes where the window shape is part of the architectural character. Winslow Windows & Doors templates and orders each unit to the exact opening, so the replacement fits without forcing or framing modifications.
For a direct replacement of a same-size geometric window, installation typically takes one day on site. The bigger variable is factory lead time, which is usually 4 to 10 weeks for a custom-shaped impact unit depending on the manufacturer and the glass package. We confirm the schedule before you commit and keep you informed if anything changes at the factory level. Call (904) 478-8983 and we’ll give you an honest current estimate.
Most custom impact windows in Coral Gables fall between $900 and $2,800 per unit installed, with large or highly shaped units running higher. Oversized openings and architecturally complex shapes can reach $5,000 or more per opening. The exact number depends on the brand, the size, the wind-load requirements, and whether any structural work is needed. Get a free line-item estimate by calling (904) 478-8983, and remember we give free second opinions on any written competitor estimate.

A live person answers our phone 24/7, and we’ll guide you through what to do until our crew arrives.

Every custom window installation by Winslow Windows & Doors carries the Done Right Promise: if it’s not done right, we make it right. That covers our workmanship, and the window itself carries the manufacturer’s warranty, which varies by brand and product line. We register every warranty on your behalf and keep the paperwork on file, so if you ever need to make a claim, you call us, not a 1-800 call center. That’s the standard Ed Winslow has worked under since 2011.
Clear furniture and decor away from the window opening, inside and out, and make sure the installers have a clear path from the door to the work area. Move vehicles out of the driveway so we can stage materials and glass safely. We protect the floors and surrounding areas, but removing your own fragile items ahead of time is always a good idea. If you have questions about what to expect on install day, call (904) 478-8983 and ask; a real person answers.
