Custom & Geometric Windows in Coral Gables - Free In-Home Measure, Written Price

Fast, Reliable Custom & Geometric Windows Across Coral Gables

Custom and geometric window work in Coral Gables is rarely a simple swap. Most homes here were built between 1920 and 1940 from solid oolitic limestone, and the City’s Historic Preservation Board reviews window replacements on Merrick-era homes with a level of scrutiny you won’t find anywhere else in Miami-Dade. A standard off-the-shelf impact window can get rejected mid-project because the muntin pattern is a quarter-inch too wide. That’s the reality we work in every week. Winslow Windows & Doors has been fabricating and installing custom impact windows, arched units, and geometric shapes that meet both Miami-Dade NOA requirements and Coral Gables preservation standards since 2011. Call (863) 862-5435 and you’ll get a live person who knows this city’s houses, not a call center.

We coordinate scheduling and dispatch from our Miami (South FL) office, and our crews serve Coral Gables locally. When you call about an arched casement on Alhambra Circle or an oversized picture window facing Biscayne Bay, the person on the phone understands what you’re describing.

Why Winslow Windows & Doors Is Coral Gables’s Preferred Custom & Geometric Windows Company

Ed Winslow founded this company in 2011, and his name is still on every job we do. That’s not marketing language. When a homeowner on Hardee Road asks who to call if something isn’t right a year from now, the answer is Ed. We publish our address and license number. We stand behind every installation with the 36500-Day Done Right Promise: if it’s not done right, we make it right, period. No national chain will put a century-long accountability standard in writing. We do.

Coral Gables homeowners have a specific set of expectations, and they’ve usually been through a few contractor letdowns before finding us. They want someone who shows up on time, sends a background-checked technician in uniform, and writes an estimate with actual line-item pricing instead of vague allowances. That’s how we’ve built our reputation from the Biltmore area south to the communities off Old Cutler Road. Our clients in Coral Gables consistently tell us the same thing: the quote matched the invoice, the crew knew how to work inside a historic masonry opening, and the permit package passed the Historic Preservation Board without a fight.

We answer our phones 24 hours a day, 7 days a week. No voicemail trees. No next-business-day callback. When you’re dealing with a custom window that’s been rejected or a rusted frame that’s letting in rain, you want a human on the other end. You get one.

Our Custom & Geometric Windows Services in Coral Gables

Every custom window project in Coral Gables starts with the same question: what will the Historic Preservation Board accept, and what does Miami-Dade’s HVHZ wind zone require? The two answers aren’t always compatible with a standard catalog product. Our Custom & Geometric Windows team handles both from day one.

Custom Impact Windows

Off-the-shelf impact windows carry a Miami-Dade NOA, which means they’ve passed the county’s missile-impact and pressure cycling tests. But an NOA doesn’t mean the Historic Preservation Board will approve it. In Coral Gables, a Merrick-era home with original casement windows often needs a custom-fabricated impact unit that replicates the original sightline width, exterior color, and simulated divided lite profile. That’s the double gate we navigate on every job. We fabricate custom impact windows in aluminum and aluminum-clad wood, matched to the original fenestration and documented for the board submission.

Geometric & Shaped Windows

Triangles, trapezoids, circles, half-rounds, pentagons, and true geometric combinations are common in Coral Gables homes from the 1920s and 1930s, especially on front elevations and stairwells. Standard catalog geometry doesn’t fit these openings. We measure every opening at the rough buck, not just the finished frame, because coral rock walls often shift slightly over 90 years and the true dimensions aren’t square. A geometric unit that’s fabricated a half-inch off won’t anchor correctly into the masonry and can deflect dangerously under hurricane wind pressure.

Arched & Curved Windows

Arched windows are the single most common custom request we get from Coral Gables homeowners, particularly in the Mediterranean Revival homes along Riviera Drive and the streets radiating off Granada Boulevard. The arch radius has to match the original exactly, or the window reads as a cheap replacement from the street. We fabricate true-radius arched units, not segmented approximations, and we match the original spring line. On a recent job off Hardee Road, we replaced three arched custom impact windows after the original steel casements showed rusted jambs and failed laminated glass interlayers from decades of Biscayne Bay salt air. We installed ES Windows thermally broken aluminum units with a custom simulated divided lite pattern to match the original fenestration, then documented the Miami-Dade NOA and Florida Product Approval for the Historic Preservation Board submission.

Oversized Openings

Large picture windows, corner glass assemblies, and wall-to-wall sliding door systems are common in the mid-century and infill contemporary homes scattered through Coral Gables, but they’re also found in the garden rooms of older Mediterranean Revival estates. Oversized openings need engineering, not just installation. Glass area, design pressure ratings, and anchoring into coral rock walls all change the fabrication spec. A 12-foot-wide opening with a 5-foot-tall fixed panel over an operable unit needs mullions rated for the full assembly, not just the individual units. We handle the structural calculations and the installation.

Trusted Brands We Service in Coral Gables

We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Coral Gables historic work, we lean on ES Windows and CGI most often because their aluminum profiles and custom color capabilities match what the Preservation Board expects, but the right product depends on the opening. We keep local stock of replacement parts and service hardware for the brands we install, which means a failed balance or a corroded hinge on a Coral Gables custom window doesn’t leave you waiting three weeks for a warranty part from out of state.

Common Custom & Geometric Windows Problems We See in Coral Gables Homes

• Historic Preservation Board rejection mid-project. A contractor buys an off-the-shelf NOA impact window, installs it or tries to, and the board rejects the sightline width or muntin profile. The owner is left with a stalled permit, a fabricated unit they can’t return, and custom fabrication costs on top. We submit the preservation packet before fabrication.
• Improper anchoring into coral rock walls. Standard wood-frame fasteners pull out of oolitic limestone under design pressure. The jamb deflects, the NOA wind mitigation credit is voided, and the window leaks. We use masonry-specific anchoring schedules and corrosion-resistant fasteners, matched to the wall condition we find.
• Marine salt-air corrosion on painted aluminum frames. Homes within a mile of Biscayne Bay see hardware failure and frame pitting within 5 to 7 years on standard painted aluminum. Weep holes clog with salt scale and water backs up into custom geometric corners that are expensive to reseal. We specify marine-grade finishes or anodized aluminum where the salt exposure demands it.
• Failed laminated glass interlayers in original steel casements. Decades of salt air and thermal cycling cause the interlayer in old laminated glass to haze and delaminate. The window still passes visual inspection but no longer carries an impact rating. Replacement means custom fabrication, not a stock unit.

Pricing for Custom & Geometric Windows in Coral Gables, FL

What Custom & Geometric Windows Costs in Coral Gables

Standard impact windows generally run $800 to $1,500 per window installed. Impact single-hung units land between $900 and $1,800 depending on size and frame material. Large or custom openings like the geometric and arched work common in Coral Gables run $2,500 to $5,000 per opening. Whole-home packages for a typical 1920s Mediterranean Revival with 15 to 25 openings fall between $8,000 and $25,000, and historically matched custom work can push higher. What moves the price here is opening count, wind zone requirements, floor height (larger glass areas on upper floors carry higher design pressure ratings), and frame material. Coral Gables’s 170 mph design wind speed requirement and Historic Preservation Board documentation add cost you won’t see in unincorporated Miami-Dade. Call (863) 862-5435 and we’ll do a free in-home measure and give you a written line-item quote.

Florida Pays You Back

Florida has real incentives for impact window and door upgrades, and Coral Gables homeowners can stack several of them. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, including impact windows and doors. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit covers 30% of product cost up to $600 per year on qualifying energy-efficient units. After a wind-mitigation inspection, which typically costs $75 to $150, many Coral Gables homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Programs and carrier rules change, so we never guarantee a specific credit amount, but we document every installation with the NOA and product approval paperwork your insurance company needs.

One thing worth understanding before you decide between impact windows and hurricane shutters: shutters only protect when someone is home to deploy them, and they do nothing for day-to-day security, UV fading, or energy loss. Impact windows protect around the clock without any action from you. A properly anchored Miami-Dade NOA impact window is permanent protection. That comparison matters for Coral Gables homeowners who travel for part of the year and need their homes protected whether or not a storm is forecast.
