Fast, Reliable Impact Windows Across Coral Gables
Impact window replacement in Coral Gables typically runs $1,200-$2,800 per opening installed, with whole-home retrofits on Mediterranean Revival properties commonly landing between $14,000 and $32,000. The numbers climb fast here because nearly every pre-1950s Coral Gables home has non-standard arched openings that require custom-radius fabrication, and because every single project must clear both Miami-Dade HVHZ product approval and the City of Coral Gables Board of Architects design review before a permit gets issued. We know that process cold. Call (727) 860-0593 and you’ll get Ed Winslow’s team, not a call center.
Our crews work Coral Gables weekly, from the Biltmore district down to the Riviera neighborhood, and we’ve learned exactly how this city’s older homes behave when the salt air off Biscayne Bay meets aluminum frames that were never thermally broken. That local knowledge changes what we specify, how we price, and how we sequence the work.
Why Winslow Windows & Doors Is Coral Gables’s Preferred Impact Windows Company
Ed Winslow’s name is on the door, and on every job we do. We’ve been installing Impact Windows across Miami-Dade since 2011, and Coral Gables has always been the market that demands the most from an installer. The Board of Architects review alone filters out contractors who don’t understand Mediterranean Revival proportions, arch radii, or the difference between a product approval and a design approval. We’ve sat through enough of those hearings to know exactly what the board flags and what it wave through.
Our Coral Gables customers consistently tell us the same thing: they called because they’d been quoted stock units for arched openings that would never pass design review, and they stayed because we handled the board package, the permit, and the custom fabrication without them having to chase anything. You won’t find our name on a ticket-number queue. You’ll find a live person on the phone at 2 a.m., and a technician in uniform who arrives already knowing the job’s history.
Every estimate is free. Every price is fixed in writing before we order a single unit. And the Done Right Promise means if it’s not done right, we come back and make it right. That’s not a warranty card. That’s Ed’s word.
Our Impact Windows Services in Coral Gables
Custom Arched Impact Window Replacement
Most Coral Gables homes built between the 1920s and 1950s have at least one arched opening, and almost none of those arches match a manufacturer’s stock radius. We order custom-radius units from CWS and ECO Window Systems with lead times of 10 to 16 weeks, and we price that lead time honestly from day one. On a 1920s Mediterranean Revival home near the Biltmore, our crew replaced three arched openings with custom-radius ECO Window Systems impact units. The original oolitic limestone jambs were out of square by up to 3/4 of an inch, so we scribed each frame and used a laminated glass interlayer to preserve the original sightlines while still hitting the required design pressure. That’s the kind of work Coral Gables demands, and it’s the kind we do.

Whole-Home Impact Window Retrofit
Full retrofits in Coral Gables neighborhoods like Country Club Section and Hammock Oaks typically run $14,000 to $32,000 depending on opening count and window type. We handle the entire sequence: measure, board package, permit, fabrication, installation, and final inspection. You get one point of contact the whole way through, and you get a written line-item quote before anything is ordered.

Impact Window and Door Replacement for Historic Homes
Coral Gables has dozens of local historic districts and individually landmarked properties. Those projects add a preservation review on top of the Board of Architects, which means the design package has to be tighter and the product choices have to be justifiable on architectural merit. We’ve worked with the board on simulated divided lites, specific frame finishes, and arch proportions that preserve the George Merrick-era character while meeting current HVHZ impact standards.

Impact Garage Doors and Entry Doors
A surprising number of Coral Gables homes still have non-impact-rated garage doors, which negates wind-mitigation credits on the entire opening. We install Miami-Dade approved impact garage doors, along with Therma-Tru entry doors, and we coordinate the frame detailing so the Board of Architects doesn’t have reason to bounce the application.

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. For Coral Gables specifically, we often specify ECO Window Systems and CWS because their custom-radius capabilities and frame finish options line up with what the Board of Architects approves without a fight. When a specific finish or simulated divided lite pattern is required, we know which manufacturer can deliver it without voiding the Miami-Dade NOA. That saves Coral Gables homeowners weeks on the front end.
Common Impact Windows Problems We See in Coral Gables Homes
- Stock arch radius specified for a custom opening. The manufacturer’s standard arch almost never matches a 1920s Merrick-era radius. The unit arrives, doesn’t fit, and the homeowner eats a 10 to 16 week reorder. We verify every radius against the opening before ordering.
- Non-thermally-broken aluminum frames corroding from Biscayne Bay salt air. Coral Gables sits roughly two miles from the bay, and that salt exposure accelerates galvanic corrosion fast. We specify thermally broken framing on every retrofit, which also helps the board’s long-term durability expectations.
- Price fixed before Board of Architects approval. When the board forces a more expensive custom finish or a specific simulated divided lite pattern after the contract is signed, a contractor who already committed to a price is either going to cut corners or hit you with a change order. Our pricing holds, and we build the board’s likely requirements into the original quote.
- Original limestone jambs out of square. Coral rock and CBS construction shift over time. We measure every opening on all four sides before ordering, and we scribe frames as needed so the install is clean and the seal is tight.
Pricing for Impact Windows in Coral Gables, FL
Standard impact single-hung windows in Coral Gables run $900 to $1,800 per unit installed. Most mid-range impact windows fall between $800 and $1,500 per window, but Coral Gables’s older housing stock pushes many projects into the custom range. Large or custom arched openings typically land at $2,500 to $5,000 each, and whole-home packages on 3,000-plus square foot Mediterranean Revival homes run $8,000 to $25,000 or more. Your price depends on opening count, floor height, frame material, and whether the Board of Architects requires custom finishes or simulated divided lites.

What Impact Windows Costs in Coral Gables
Here’s the honest math for this city. A standard impact window in Coral Gables runs $800 to $1,500 per window installed. Impact single-hung units run $900 to $1,800. Large or custom openings, and Coral Gables has far more of those than most Miami-Dade cities, run $2,500 to $5,000 per opening. A whole-home package on a typical 2,500 to 3,500 square foot Mediterranean Revival home lands between $8,000 and $25,000 or more, and the top end is almost always driven by custom arch work and board-mandated finishes. Three things move your number: how many openings you have, whether they’re arched or standard, and what frame material and finish the board requires. We give you the price in writing before anything is ordered. Free in-home measure, free written quote.
Florida Pays You Back
The incentive stack for Coral Gables homeowners is real, and it’s worth understanding before you write the check. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also exempts impact-resistant windows and doors from sales tax. On top of that, the federal 25C energy credit refunds 30% of product cost on qualifying units, up to $600 per year. And once installed, most Coral Gables homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy after a wind-mitigation inspection, which typically costs $75 to $150. Programs and carrier decisions set the final numbers, not us, but we’ll walk you through every one of them.
One more comparison worth making: impact windows outperform hurricane shutters permanently. Shutters only protect you when someone’s home to hang them, and they do nothing for day-to-day security, energy performance, or the Board of Architects’ design expectations. Impact-rated glazing is always in place, always working, and in Coral Gables it’s the only compliance path that doesn’t involve panels you’ll lose in the garage.

FAQs - Impact Windows in Coral Gables
Coral Gables requires Board of Architects approval because the city’s 1920s Mediterranean Revival character is protected by code. Any exterior window or door replacement triggers design review, and the board can reject a PGT or CGI stock unit for its frame finish, arch radius, or subdivision pattern before a permit is even issued. That’s why we prepare the board package alongside the product approval documentation, and why we specify custom finishes from the start. Call (727) 860-0593 and we’ll tell you exactly what your project needs to pass.
Miami-Dade NOA (Notice of Acceptance) is the stricter of the two, requiring testing that matches this region’s High Velocity Hurricane Zone conditions. Florida Product Approval is the statewide equivalent, but Coral Gables sits in Miami-Dade County, so your units need Miami-Dade Product Approval to pass permit review. Not every product with a Florida Product Approval carries a Miami-Dade NOA, and the board will check. We specify only Miami-Dade approved units with design pressures matched to your specific openings, which in this wind zone means ratings up to +/-100 depending on location and floor height.
Custom arched impact windows in Coral Gables typically take 10 to 16 weeks from order to delivery. That lead time is set by the manufacturer, not by us, and any contractor who quotes you standard 4-6 week timing on arced units is going to blow the schedule. We quote custom fabrication honestly, and we’ve built our project sequencing around those real lead times so your permit doesn’t expire while you wait. Call (727) 860-0593 to get a realistic timeline for your specific openings.
Yes, impact-rated windows are a primary wind mitigation measure in Coral Gables, and they typically trigger the largest single premium credit most carriers offer on the windstorm portion of your policy. Miami-Dade’s HVHZ mandate already requires impact glazing on every opening, so replacing old non-rated windows moves you into full compliance and gives the insurer documentation to reduce your windstorm premium. We provide the installation documentation your wind-mitigation inspector needs.
Yes. Impact windows in Coral Gables typically cut heat gain through the glass by 30 to 50 percent compared to single-pane or older aluminum-frame windows, which translates directly into lower AC run times in a climate where the bay keeps humidity high night and day. The laminated glass interlayer also blocks significant UV, protecting interior finishes in homes where original millwork and cabinetry are part of the property’s value. The federal 25C energy credit applies to qualifying units, and we’ll help you document that at purchase.
