AfterFast, Reliable Custom & Geometric Windows Across Coral Gables
Custom and geometric windows in Coral Gables cost between $2,500 and $5,000 per opening for true arched or radius work, and the most important variable isn’t the glass. It’s whether the unit carries a Miami-Dade HVHZ Notice of Acceptance (NOA) and whether the frame profile will pass Coral Gables’s own Board of Architects review. We’ve been installing impact-rated custom windows in this city long enough to know both gates cold. Call (239) 310-4121 and you’ll get Ed Winslow’s team, not a call center.
Every job in Coral Gables runs on a different clock than work in Kendall or Hialeah. Permitting takes longer. The Board of Architects meets on its own schedule. And the homes themselves, many of them 1920s Mediterranean Revival with thick coral rock walls and arched openings, don’t forgive shortcuts. We plan for all of it before we measure the first opening.
Why Winslow Windows & Doors Is Coral Gables’s Preferred Custom & Geometric Windows Company
Ed Winslow put his name on this business in 2011, and that’s not a marketing line. It means when a Coral Gables homeowner calls about a rejected permit or a frame that doesn’t sit right, the person accountable is reachable. We publish our address and license number. We don’t hide behind a ticket system.
Our technicians arrive in uniform, background-checked, and they know Coral Gables specifically. They know that an arched opening on Alhambra Circle isn’t the same as one on Riviera Drive, and they know what the Board of Architects flagged last month because we track every review outcome. Homeowners in the Biltmore and Country Club neighborhoods call us first because we’ve already done the homework on their street’s design overlay. And when you call at 2 a.m. with a window that won’t hold after a storm, a live person answers. Every time.
Our Custom & Geometric Windows Services in Coral Gables
Custom Impact Windows
Coral Gables sits inside Miami-Dade County’s High Velocity Hurricane Zone, which runs the toughest impact-window code in the country. Our Custom & Geometric Windows team cuts every unit to the opening, not the other way around. That matters here because 1920s and 1930s homes rarely have a square, plumb opening anywhere in the envelope. We match the glass package to the design pressure the opening actually needs, and we pull every permit before a saw touches your wall.
Geometric & Shaped Windows
Triangles, trapezoids, half-rounds, octagons. Coral Gables has them all, usually in the same house. These units almost never exist as stock inventory, which is why big-box installers either pass on the job or jimmy a rectangle into a hole it doesn’t fit. We order factory-fabricated geometric shapes with tempered, laminated impact glass and frames rated for the HVHZ wind load, then anchor them into coral rock with epoxy-set stainless hardware instead of tapcons.
Arched & Curved Windows
Arched casements are the signature of Mediterranean Revival architecture, and Coral Gables has thousands of them. A true radius arch cannot be field-bent from a straight frame without voiding the NOA certification, so we order factory-rolled aluminum to the exact radius of your opening. We’ve done arched tops over fixed sashes, full-radius casements, and eyebrow windows where the curve is gentle enough that even the glass has to be custom cut. One opening. One unit. No field modifications.
Oversized Openings
When a Coral Gables homeowner opens a wall for a floor-to-ceiling window or a corner glass assembly, the engineering changes. Bigger openings mean higher design pressure, heavier glass, and frames that have to carry more load. We pull structural details for the permit package and specify units rated for the wind zone and the height above grade. This is not a window you order from a catalog.

Trusted Brands We Service in Coral Gables
We’re an authorized installer for PGT, CGI, three manufacturers whose Coral Gables configurations we know intimately. We help homeowners choose the right frame, glass, and SDL bar profile for the Board of Architects review, and we order directly from the factory with the exact NOA numbers tied to your permit. When a Coral Gables customer has a glass break or a hardware failure, we can often get replacement parts faster because we know the product lines and the local code path.
Common Custom & Geometric Windows Problems We See in Coral Gables Homes
- Flat-profile SDL bars rejected by the Board of Architects. The standard simulated divided light bars that pass anywhere else in Miami-Dade look wrong on a 1930s Mediterranean Revival window. Coral Gables reviewers want raised, thick-profile muntins that match the original glazing bars. We specify those from day one.
- Frames anchored into crumbling coral rock with generic screws. Oolitic limestone is soft and porous. A standard tapcon will loosen, and a large-missile impact will pull the frame right out. We use epoxy-set stainless anchors rated for the opening’s design pressure.
- Field-cut frames that void the NOA. Some installers buy a rectangular impact window and try to trim it to fit a radius opening on site. The moment that frame is modified, the product approval is dead and the permit dies with it. Factory-fabricated geometry is the only compliant path.
- Arched openings measured wrong, then re-ordered twice. If you take radius measurements from one point only, you’ll miss that the arch is asymmetric. We measure the full arc in sections, order the exact radius, and avoid the three-month delay a re-order creates.
Pricing for Custom & Geometric Windows in Coral Gables, FL
What Custom & Geometric Windows Costs in Coral Gables
Impact windows generally run $800 to $1,500 per window installed across South Florida. Impact single-hung units fall between $900 and $1,800. A true arched or geometric opening in Coral Gables, one that needs a factory-fabricated frame and Board of Architects-ready detailing, runs $2,500 to $5,000. Whole-home packages on a large Mediterranean Revival property can reach $8,000 to $25,000 or more depending on opening count and wind-zone requirements. What moves the price here: the number of non-rectangular openings, your elevation above grade, the frame material, and whether the review requires thick-profile SDL bars and custom glass.

Florida Pays You Back
The incentives stack, but read the fine print. My Safe Florida Home matching grants can top out at $10,000 for qualifying wind-mitigation upgrades, and impact-resistant windows and doors carry a Florida sales-tax exemption. On the federal side, the 25C energy credit covers 30% of product cost, up to $600 a year on qualifying units. After a wind-mitigation inspection (which runs about $75 to $150), many homeowners also see windstorm-premium credits averaging around 25% on the wind damage portion of their policy. Programs change and carriers set final numbers, so we’ll point you to the inspection and rebate paperwork without promising a dollar figure you won’t get.

FAQs - Custom & Geometric Windows in Coral Gables
Yes. Every custom arched window in Coral Gables must carry a Miami-Dade HVHZ Notice of Acceptance that matches the exact configuration, and any exterior change visible from the street must pass design review by the city’s Board of Architects. The two reviews are separate, and passing one does not guarantee the other. Call (239) 310-4121 and we’ll walk you through both before you spend a dollar on fabrication.
Raised, thick-profile simulated divided light bars. Flat-profile SDL muntins, which are the standard on most impact windows, get flagged routinely for not matching the original Mediterranean Revival glazing. We specify the thicker profile from the factory and note it on the submittal drawings. It saves a rejection cycle and often gets approved on the first review.
In most cases, yes, the opening can be reused if the surrounding coral rock is sound. The frames are factory-fabricated to the existing arch radius, which avoids cutting into the stone. If the jamb has softened, as we often see on 1930s houses, we repair it before anchoring, then use epoxy-set stainless anchors instead of mechanical screws. The goal is a tight fit without disturbing more of the wall than necessary.
The windstorm portion of your Florida homeowners policy is the part that reacts to impact-window documentation. After a wind mitigation inspection, typically $75 to $150, many carriers offer credits averaging around 25% on that portion. The key is documented compliance: the NOA number, the permit, the final inspection. A cheap install with no paper trail won’t move your premium at all, and it may hurt a future claim.
Yes, and the reason is salt. Coral Gables homes near the Bay sit in one of the most corrosion-aggressive environments in the county. Anodized aluminum holds its finish and structural integrity far longer than painted or mill-finish frames, and proper weep-hole orientation keeps drainage working even with wind-driven salt spray. Call (239) 310-4121 for an exact recommendation on your specific elevation and exposure, and we’ll include it in the written quote.
