Fast, Reliable Window Replacement Across Coral Gables
Window replacement in Coral Gables runs $800 to $1,500 per opening for a standard impact-rated unit installed, and the job usually takes one day once your windows arrive. But here’s what you’ll only hear from a crew that actually works this city: every opening also needs a separate design approval from the Coral Gables Board of Architects before the building department will sign off. Skip that step and you’re looking at a stop-work order, not a finished job. We’ve spent over 42 years in South Florida glasswork, and we schedule that architectural submittal weeks ahead so your installation clears final inspection without a stall. Call (561) 489-4036 for a free in-home measure and a written quote that lays out both approval steps in plain language.
Why TruePane Windows & Doors Is Coral Gables’s Preferred Window Replacement Company
TruePane was founded in 2008 by Dale Kessler, a second-generation glazier who got tired of seeing out-of-true installs and voided warranties left for homeowners to clean up. Our crews know Coral Gables the way you do: the arched masonry openings in the Granada Golf Course neighborhoods, the salt air along Coral Gables Waterway, and the Board of Architects requirements that out-of-town contractors keep tripping over. We’re an authorized installer for PGT, CGI, and ES Windows, among more than a dozen lines, so the impact units we quote actually meet Miami-Dade NOA standards for your wind zone, not whatever the big-box store had on the shelf.
Coral Gables homeowners call us because we answer the phone with a live person, 24 hours a day, seven days a week. No voicemail tree, no call center, no waiting three days for a callback. Dale still answers the phone himself most days. And when our background-checked, uniformed technicians arrive, they measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves your driveway. That’s the Keystone Standard. If the pane is not true, the job is not done.
Our 90-Day Done Right Promise is exactly what it sounds like: if something about the install isn’t right, we make it right. No paperwork fights, no arguing, no fine print that covers neither. That’s why homeowners who’ve been in their Coral Gables homes for twenty years or more tend to hand us the job and then hand us the next one. A square deal, in writing.
Our Window Replacement Services in Coral Gables
Full Frame Replacement
When the original frame is rotted, out of square, or simply not deep enough to carry a modern impact-rated unit, full frame replacement is the only honest fix. We pull the entire old window, framing and all, then set a properly flashed, properly shimmed new opening that matches the surrounding stucco line. In Coral Gables’s 1920s Mediterranean Revival homes, we frequently find original steel or wood casements with rusted frames and crumbling mortar surrounds. Full frame replacement lets us correct the rough opening and install a NOA-certified unit in the correct profile, whether that’s a rectangular double-hung or a custom arched casement.

Insert Window Replacement
If your existing frames are square, sound, and deep enough, an insert replacement drops into the old frame with minimal disturbance to interior trim and exterior stucco. This is usually the most economical path on Coral Gables homes built or renovated in the 1980s and 1990s, where the openings are standard rectangles and the frames just need new insulated glazing and fresh hardware. Inserts install fast, often in a single day for an average opening count, and they don’t require city architectural review beyond the standard permit path, though the Board of Architects approval still applies to the product choice.

Vinyl Replacement Windows
Vinyl makes sense when you want low maintenance and good insulation without paying for a premium frame material. But here’s the Coral Gables catch: many older homes in the city’s historic zones cannot accept standard white vinyl rectangular units. The Board of Architects will reject them if the surrounding homes carry bronze, dark bronze, or custom-profile casings. We quote vinyl where it’s appropriate and code-compliant, and we’ll tell you plainly when it isn’t. What we won’t do is sell you a window that fails your final inspection.

Energy-Efficient Upgrade
Swapping single-pane glass for Low-E insulated impact units is one of the fastest ways to cut your cooling bill in Coral Gables, where air conditioning runs ten months a year. The Low-E coating blocks solar heat gain while the laminated impact glass keeps the opening code-compliant. For homes along Coral Gables Waterway or near the bay, we recommend marine-grade frame finishes and stainless hardware. Salt air eats standard aluminum weep holes and multi-point locks within a few seasons, and replacing them twice costs more than specifying them correctly once.

Trusted Brands We Service in Coral Gables
We’re an authorized installer for PGT, CGI, and ES Windows, and we stock common replacement hardware and laminated glass panels locally so Coral Gables customers aren’t waiting three weeks for a sash or a lock to ship from out of state. If your existing windows are PGT or CGI, we can usually match the original product line and keep both warranty layers intact. If you’re replacing with a different brand, we’ll show you the NOA documentation side by side with the competing line so you see exactly what you’re buying before you sign.
Common Window Replacement Problems We See in Coral Gables Homes
- Stop-work orders from skipped architectural review. A contractor pulls the building permit, installs impact windows, and then the inspector asks for the Board of Architects approval letter. It’s not in the file. The job stalls for weeks while the design review happens retroactively. We sequence that submittal first, because waiting for the city to sort it out after the fact is the most expensive avoidable delay in this market.
- Standard rectangular units jammed into arched openings. Coral Gables’s Mediterranean Revival stock is dense with arched window openings that were never meant to take a stock vinyl rectangle. Squaring off an arch or filling it with stucco and a smaller square window violates the city’s design standards and fails final inspection. The correct fix is a custom-fabricated arched impact unit, usually in bronze or dark bronze, with a profile the Board of Architects will sign off on.
- Salt corrosion on hardware and frames near the bay. The eastern edge of Coral Gables along Biscayne Bay delivers salt-laden air that works on aluminum, weep holes, and multi-point locks year-round. Non-marine-grade hardware corrodes within a few seasons, and the window that still looks fine from the porch won’t lock properly or drain correctly. Specifying marine finishes up front costs a little more and lasts a decade longer.
- Builder-grade windows in newer master-planned sections failing early. In the planned communities built since the 1990s, original windows were often chosen to hit a builder’s budget, not to hold up in a Category 4 wind field. Fogged seals, warped sashes, and failed weeping systems show up within ten to fifteen years. Replacing those before a storm exposes the gap is cheaper than replacing them after water has already found the interior drywall.
Pricing for Window Replacement in Coral Gables, FL
A standard impact-rated window in Coral Gables runs $800 to $1,500 per unit installed. Impact single-hung units run $900 to $1,800 depending on size and design pressure. Large openings, custom arched units, and second-story work push into the $2,500 to $5,000 range per window, and a whole-home package typically lands between $8,000 and $25,000 or more depending on the opening count and the condition of existing frames. What moves the price: whether you need full frame replacement or inserts, whether the opening is arched or rectangular, what wind zone your street falls in, and whether the Board of Architects requires a custom finish or profile. We never quote a price without measuring the opening and showing you the NOA documentation for the exact unit we’d install. Call (561) 489-4036 for a free in-home measure and written line-item quote. No surprises on the bill, ever.
What Window Replacement Costs in Coral Gables
Let’s put real numbers on it. A standard impact window installed in a Coral Gables opening runs $800 to $1,500. Impact single-hung units run $900 to $1,800, and a large picture window or custom arch can run $2,500 to $5,000. Whole-home packages on a typical three-bedroom Mediterranean Revival home with fifteen to twenty openings usually land between $8,000 and $25,000, with custom arched fabrication pushing higher. The variables are opening count, floor height, whether the existing frame can take an insert or needs full replacement, and the design pressure rating your specific wind zone requires. We measure every opening twice, quote manufacturer lines side by side on paper, and hand you a written number before you commit. The estimate is free, and the price we quote is the price you pay.
Florida Pays You Back
There’s a stack of incentives 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, including impact windows in many cases. Florida also exempts impact-resistant windows and doors from sales tax, which shaves a meaningful percentage off the top. On the federal side, the 25C energy credit returns 30% of the product cost, up to $600 per year on qualifying energy-efficient units. And after a wind-mitigation inspection, most Coral Gables homeowners see their windstorm premium drop, on average around 25% on the windstorm portion of the policy. The inspection runs $75 to $150, and the credit is set by your carrier, not by us. We’ll point you to the right program and let the state and your insurer set the final numbers.
Impact Windows vs. Hurricane Shutters
Shutters protect glass from flying debris, but they only work if you’re home to hang them, and they do nothing for solar heat gain, noise, or air infiltration the other 364 days a year. Impact windows are permanent protection: laminated glass that stays in its frame when debris hits, meets Miami-Dade NOA standards without panels or tracks, and cuts cooling costs year-round. You don’t have to drag corrugated panels out of a shed in August or strap down accordion tracks that have seized in the salt air. For a Coral Gables homeowner who’s in the same house for another twenty years, impact-rated replacement windows usually make more sense than a shutter retrofit on a window that was never energy-efficient to begin with.

FAQs - Window Replacement in Coral Gables
Yes. Every window and door replacement in Coral Gables requires both a Miami-Dade Notice of Acceptance for hurricane-impact performance and a separate design approval from the Board of Architects confirming the product’s profile, material, and finish meet the city’s Mediterranean Revival design standards. No other South Florida city imposes this dual sign-off, and the building department won’t issue a final inspection sign-off unless the Board of Architects approval letter is already in the file. We plan for both from the first measure. Call (561) 489-4036 and we’ll walk you through the sequence before you spend a dollar.
No. Standard rectangular impact units do not fit a true arched masonry opening without either squaring off the arch, which violates the Board of Architects design standards, or filling the gap with stucco, which leaves a smaller window and a patch that never looks right. The correct fix is a custom-fabricated arched impact unit in a profile and finish that match the original opening, usually bronze or dark bronze. We replaced a set of original steel casements near Coral Gables Waterway with custom PGT arched impact units in a dark bronze profile and sequenced the architectural submittal six weeks before install so the final inspection cleared without a stop-work order.
Schedule it at least four to six weeks before your installation date. The Board of Architects meets on its own calendar, and design review can take several weeks depending on the agenda load. Local permit techs know that the building department won’t sign off without that approval letter in the file, so experienced crews submit early and install after the approval clears. We schedule the architectural submittal before we order custom fabrication, which means your windows arrive with the approval already in hand. Call (561) 489-4036 and we’ll map the timeline for your specific opening set.
Choose marine-grade frame finishes and stainless steel or coated multi-point hardware. Salt-laden air along the Coral Gables Waterway and the bay’s eastern edge accelerates corrosion on standard aluminum frames, weep holes, and locking mechanisms within a few seasons. A dark bronze or painted marine finish holds up far better than mill aluminum, and the hardware should be specified for coastal exposure, not inland use. Spending a little more on the right finish up front means you’re not replacing hardware twice in a decade.
Yes. Low-E insulated impact glass blocks a meaningful share of solar heat gain while the laminated glass keeps the opening code-compliant for Miami-Dade’s wind-borne debris region. In Coral Gables, where air conditioning runs most months, reducing that heat load on the glass usually shows up on the electric bill within the first full cooling season. The exact savings depend on your home’s orientation, overhangs, and how many square feet of glass you replace, but homeowners who swap out old single-pane units for Low-E impact glass typically see a noticeable drop. We’ll show you the product documentation before you buy, and the install is covered by the 90-Day Done Right Promise.
