AfterGeometric & Shaped Windows in Coral Gables, FL
Custom & Geometric Windows - circles, octagons, arches, trapezoids, and custom polygons - are specialty units built to fit openings that no standard catalog size will ever match. In Coral Gables, where Mediterranean Revival architecture sets the tone for entire neighborhoods, these windows are not decorative extras; they’re structural features that define the look of a home and admit light into spaces a rectangular window simply cannot reach. At Winslow Windows & Doors, we’ve been measuring, sourcing, and installing shaped windows in Coral Gables since 2011, and Ed Winslow handles every project with the same standard: built to fit, impact-rated for South Florida conditions, and backed by the Done Right Promise.
If you’re replacing a failing arched unit in Coral Way, adding an impact-rated circle window above your front entry in Biltmore, or retrofitting a trapezoid transom in the Crafts Section, call us at (904) 478-8983 – a live person answers every call, around the clock. Or start by reading about our full Custom & Geometric Windows in Coral Gables service to understand how shaped windows fit into the broader custom installation process.
When You Need Geometric & Shaped Windows
Not every homeowner realizes a shaped window has become a problem until the damage is already spreading. Here are the scenarios we see most often when we visit homes across Coral Gables:
- Failed seals on arched or circle units above entry doors. The curved perimeter on older arch windows is one of the first places seal failure shows up in South Florida’s humidity. Once the seal goes, condensation clouds the glass and moisture begins working into the surrounding masonry – a particular concern in homes built along Alhambra Circle and Old Cutler Road, where original Mediterranean facades are worth protecting.
- Impact-code non-compliance on existing shaped openings. Miami-Dade County requires impact-rated glazing on all exterior openings. Many Coral Gables homes still have single-pane decorative geometrics that passed code under older standards but are now out of compliance. Replacing them with a CGI or CWS impact-rated shaped unit brings the home current without altering the silhouette.
- Renovation or addition requiring a custom-shaped opening. When a Coral Gables homeowner adds a tower room, converts an attic, or redesigns a foyer, the resulting wall openings are rarely standard rectangles. We fabricate to the exact rough opening so the finish work is clean from day one.
- Water infiltration around the frame perimeter. Shaped windows rely on precise frame-to-wall transitions. When a previous installer cut corners on flashing or sealant, the first serious tropical rain finds every gap. We see this frequently in the Brickell Hammock area after storm season.
- Fogged or discolored glass in fixed geometric units. Many geometric windows are fixed – they don’t open – so there’s no ventilation to buffer interior heat. When the insulated glass unit (IGU) fails, the only fix is a properly matched replacement, not a patch.
- New construction or full exterior remodel needing shaped windows throughout. Architects and design-build firms working in Coral Gables regularly call us when a project spec calls for non-rectangular glazing that a big-box supplier won’t custom-cut. We source through ECO Window Systems and other authorized partners to match exact project dimensions and impact ratings.
Our Geometric & Shaped Windows Process
A shaped window job fails or succeeds at the measurement stage. Every step below is built around that reality.
- On-site assessment and exact templating. We come to the home – no trip charge inside Miami-Dade County – and take physical measurements of every dimension of the existing opening: span, rise, angle, depth of reveal, and wall thickness. For arched units we also document the radius. We photograph the surrounding masonry and check the existing flashing condition so there are no surprises mid-install.
- Upfront quote with line-item pricing. Before we order anything, you receive a written quote that breaks out the unit cost, frame finish, glazing specification, labor, and any ancillary work like stucco repair or interior trim. Upfront pricing means the number on the quote is the number on the invoice.
- Custom fabrication through authorized manufacturers. We place the order through our authorized brand network – which includes CGI, CWS, ECO Window Systems, and ES Windows depending on the shape, size, and impact requirement. Lead times for shaped units typically run two to five weeks; we give you an honest production estimate at quote time, not an optimistic one.
- Frame removal and opening preparation. Our background-checked, uniformed technicians remove the existing unit carefully, assess the rough opening for rot, moisture damage, or masonry deterioration, and correct any issues before the new frame goes in. A shaped window installed over a compromised sill will fail again – so we don’t skip this step.
- Precision installation and impact-rated sealing. The new unit is set, shimmed, and anchored per Miami-Dade NOA (Notice of Acceptance) specifications. Flashing and sealant are applied in layers – not a single bead of caulk. For arched and circle windows, we pay particular attention to the crown and the sill transitions, which are the highest-risk points for future infiltration.
- Final inspection and cleanup. We walk the installation with you, confirm the unit operates correctly (if it’s operable), verify the seal integrity, and leave the work area clean. The Done Right Promise covers every job: if something isn’t right, Ed’s name is on the door and we come back to fix it, period.
Geometric & Shaped Windows Pricing in Coral Gables
Geometric and shaped window pricing in Coral Gables depends on shape complexity, glass size, impact rating, frame finish, and whether the surrounding masonry needs any repair work. Below are honest ranges based on what we actually invoice in this market – not national averages.
| Window Type | Typical Installed Price Range (Coral Gables) |
|---|---|
| Half-round / arch (up to 36″ span) | $420 – $780 per unit |
| Circle or oval (fixed, impact-rated) | $480 – $950 per unit |
| Trapezoid or triangle (fixed or operable) | $550 – $1,050 per unit |
| Octagon or hexagon (fixed, up to 30″) | $520 – $900 per unit |
| Large custom polygon (> 40″ dimension) | $950 – $2,400+ per unit |
| Eyebrow / elliptical transom | $600 – $1,100 per unit |
A few factors that move the price within those ranges:
- Impact rating. Miami-Dade High-Velocity Hurricane Zone (HVHZ) compliance adds cost to any shaped unit because the glazing must meet stricter lamination and frame standards. This is non-negotiable for Coral Gables – it’s not an upgrade, it’s the baseline.
- Frame finish. Standard bronze anodized and white are the lowest-cost options. Custom colors, wood-look cladding, or historic-replica finishes cost more and often require longer lead times.
- Opening condition. If the existing rough opening has moisture damage or the surrounding stucco needs patching after removal, that work is quoted separately and transparently – not buried in a contingency line.
- Quantity. Homes along Coral Way or in the Country Club Prado area often have four, six, or eight geometric windows in the same facade. Multi-unit orders reduce per-unit cost because mobilization, templating, and delivery are shared across the job.
Seniors and veterans receive a permanent 10% discount on every job, and any repair over $200 qualifies for $40 off. Estimates are free. Call (904) 478-8983 and we’ll schedule an on-site measurement – no trip charge inside Miami-Dade County.
FAQs – Geometric & Shaped Windows
Can geometric windows in Coral Gables be impact-rated?
Yes – virtually every shaped window profile we install is available in Miami-Dade HVHZ-approved, Custom Impact Windows configurations. CGI and ECO Window Systems both carry NOA-certified shaped units, including arches, circles, and multi-sided polygons. The key is sourcing from a manufacturer with an active NOA for the specific shape and size you need, which is why templating comes before ordering. If a unit doesn’t have a valid NOA for Coral Gables’ wind zone, we won’t spec it – and we’ll tell you that plainly at the quote stage rather than after the inspection.
How long does it take to get a custom-shaped window made and installed?
Standard geometric shapes – half-rounds, circles, and common trapezoids – typically take two to four weeks from order to delivery. Oversized Openings and more complex custom polygons can run four to six weeks depending on the manufacturer’s current schedule. We give you a realistic lead time at quote time based on our current production contacts, not a best-case scenario designed to win the job. Installation itself is usually a half-day to one full day per opening once the unit arrives, assuming the rough opening is in good condition.
Will replacing my arch or circle windows change the look of my home?
When done correctly, no – and in most cases the home looks noticeably better. We match the profile, radius, and frame depth of the existing unit so the new window sits in the same reveal and carries the same silhouette. For Coral Gables homes with historic or Mediterranean character - particularly in the Crafts Section or along Ponce de Leon Boulevard - we work closely with homeowners on Arched & Curved Windows and, where required, with the City of Coral Gables Historic Preservation Board to confirm the replacement spec is appropriate before fabrication begins. A shaped window that doesn’t respect the original architectural proportion is a problem we avoid at the measurement stage, not after the fact.
Are there any Coral Gables permit requirements specific to shaped window replacements?
Yes. Miami-Dade County requires a permit for window replacements, including shaped and geometric units, and the City of Coral Gables has an additional layer of review for properties within designated historic districts. The permit process requires the window’s NOA documentation and, for historic properties, design review approval. Winslow Windows & Doors handles permit coordination as part of the installation process – you don’t have to navigate the city’s building department yourself. We’ve pulled permits in Coral Gables consistently since 2011 and know what the inspectors are looking for. Note that work in the historic districts may extend the timeline, which we factor into the project schedule we give you at the start.
Why Winslow Windows & Doors for Shaped Windows in Coral Gables
Coral Gables is one of the most architecturally specific cities in South Florida. The Mediterranean Revival character of neighborhoods like Biltmore, Old Cutler, and the Crafts Section isn’t accidental – it was designed by George Merrick, and the city actively works to protect it. A shaped window replacement done poorly – wrong radius, wrong frame depth, wrong finish – stands out on these streets in the worst possible way. And a shaped window installed without proper impact credentials will fail a Miami-Dade inspection and expose the homeowner to real liability.
Ed Winslow has been working in this market since Winslow Windows & Doors opened in 2011. He knows the difference between a job that passes inspection and a job that holds up over years of South Florida humidity, salt air, and summer storms. The Done Right Promise isn’t fine-print language – it’s a commitment Ed stands behind personally, because his name is on the business and his number is on the invoice.
We’re an authorized installer for CGI, CWS, ECO Window Systems, ES Windows, and other premium brands, so when a shaped unit needs to be sourced for an unusual opening in Coconut Grove-adjacent Coral Gables or a multi-window facade on Alhambra Plaza, we have the manufacturer relationships to get it right. And because we’re locally owned with a published address, you can always find us if something needs attention after the job is done.
