Fast, Reliable Window Replacement Across Coral Gables
Window replacement in Coral Gables isn’t a one-decision job. It’s a two-gate process: every unit must pass Miami-Dade County’s High-Velocity Hurricane Zone product approval, and then it has to clear the City of Coral Gables Board of Architects, which guards the 1920s Mediterranean Revival character street by street. That second gate is where homeowners lose money. We handle both approvals before ordering a single unit, and we’ve done it for enough Coral Gables homes to know exactly what the Board will flag before they flag it. Call (954) 507-3613 to talk through your windows with someone who’s been through this process more than once.
TruePane Windows & Doors serves homeowners from the Biltmore area to the Riviera and across Cocoplum, working on houses built when windows were steel and walls were coral rock. We know these houses. We know what the permit office asks for, what the Board rejects, and which manufacturers make units that get through without a fight.
Why TruePane Windows & Doors Is Coral Gables’s Preferred Window Replacement Company
Dale Kessler founded TruePane in 2008 out of a second-generation glazier’s frustration with out-of-true installs and warranties that vanished when it mattered. Years of community service, the rule on the whiteboard hasn’t changed: if the pane is not true, the job is not done. In Coral Gables, that standard gets tested in ways most installers never see: non-standard rough openings in 1920s masonry, arched window heads that don’t fit off-the-shelf units, and the Board of Architects asking for a different muntin pattern on the second or third submittal. We’ve been through all of it.
Every job gets The Keystone Standard in writing before the truck leaves: both manufacturer warranty layers registered, durations stated, no exceptions. The Done Right Promise covers the workmanship. No paperwork fights. No arguing. If it’s not done right, we make it right.
Local homeowners tell us the same thing: the live person who answers the phone at (954) 507-3613 is the reason they called. Not a voicemail tree, not a callback form. Same for the crew: background-checked, uniformed, and trained as apprentices into journeymen. They work in your home the way they’d work in their own mother’s.
Our Window Replacement Services in Coral Gables
Here’s what we actually do in Coral Gables, based on the houses that are actually here. The scope of each service below is shaped by the local housing stock: 1920s through 1940s Mediterranean Revival masonry, deep window reveals, arched openings, original steel casements, and wood windows that have spent 80 years in Biscayne Bay salt air.
Historic Window Restoration
This is the core of Coral Gables work. Homeowners with original steel or wood casements on a designated or contributing structure don’t usually want to rip those out, and the Board of Architects often won’t let them. We restore original frames where possible, rebuild sashes, replace hardware with marine-grade equivalents, and when replacement is required, we fabricate custom aluminum casements that replicate the slender profiles and historic muntin patterns the Board expects. On a 1927 Mediterranean Revival home off Alhambra Circle, we replaced original steel casements with custom thermally broken aluminum from Marvin after the Board flagged the first submittal for frame width. The units matched the originals to the eye, but carried a full Miami-Dade NOA. That’s the standard.

Full Frame Replacement
Coral Gables’ thick concrete block and coral rock construction means the rough openings are deeper than what standard replacement windows assume. You can’t just order a stock-depth unit and call it a day. Full frame replacement lets us address the actual rough opening depth, install proper jamb extensions, flash with stainless steel tape, and set the unit square in walls that haven’t been square in a century. This is the most common route for Coral Gables homeowners who want the window replaced and the opening rebuilt correctly in one job.

Energy-Efficient Upgrade
Old steel casements and single-pane wood windows in Coral Gables leak air and gain heat all day. Low-E insulated glass units with argon fill, set into properly flashed openings, change the comfort of these masonry houses meaningfully. The energy math works here because so many original windows are single-glazed and the walls, while thick, don’t provide much insulation on their own. For homeowners looking to cut utility costs, our Energy-Efficient Windows - Coral Gables service is designed specifically for these conditions. We specify glass packages that hold up to the salt air, not just to the sun. Most upgrades are completed in a single visit once the units are fabricated.

Insert Window Replacement
For Coral Gables homeowners keeping the original frames but replacing the sashes and glass, insert replacement can save the character of the house while upgrading the performance. This works when the existing frames are structurally sound, which in salt-air conditions means we check every frame for corrosion before quoting. If the frame is compromised, an insert won’t fix it, and we’ll tell you that rather than sell you a window that will fail in five years. Insert work is faster than full frame replacement and often costs less, but only when it’s actually appropriate.

Trusted Brands We Service in Coral Gables
We’re an authorized installer for more than a dozen manufacturer lines, including Andersen service in Coral Gables, so you get side-by-side quotes on paper instead of a hard sell on whatever’s in the warehouse. For Coral Gables specifically, we specify units from CGI, PGT, and ES Windows most often, these manufacturers build products that satisfy both Miami-Dade NOA requirements and the Board of Architects’ profile and finish expectations. We don’t guess. We quote you the actual unit, the actual glass package, and the actual muntin pattern before you write a check.
Common Window Replacement Problems We See in Coral Gables Homes
- Board of Architects rejection after purchase. A homeowner buys a fully NOA-certified impact window, pulls a Miami-Dade permit, installs it, and then the Board flags the muntin pattern, frame width, or finish color for conflicting with the home’s Mediterranean Revival character. The fix is a tear-out. We run Board review before ordering so this doesn’t happen on our jobs.
- Water intrusion through thick masonry walls. Coral Gables’ 1920s-1940s walls are deeper than standard replacement windows assume. An installer using stock-depth units leaves gaps that become water intrusion points during a hurricane. We fabricate custom jamb extensions and flash properly because the geometry requires it, not as an upsell.
- Salt-air corrosion of frames and hardware. Proximity to Biscayne Bay means persistent salt exposure. Non-marine-grade hardware and uncoated aluminum frames fail within a few years. We specify marine-grade finishes and thermally broken frames as standard in Coral Gables, not as an option.
- Steel casement windows that don’t seal anymore. Ninety-year-old steel casements warp, rust, and leak air. Homeowners who want to keep the original look need a restoration or a custom replacement that replicates the profile. Both are doable; neither is a stock window.
Pricing for Window Replacement in Coral Gables, FL
A full frame impact window replacement in Coral Gables typically runs $1,800 to $4,200 per opening, including the unit, installation, and both approval processes. Insert replacement, when the existing frame is sound, runs $900 to $2,100 per opening. Historic window restoration on original steel or wood casements starts around $750 per sash and rises with the extent of corrosion and the number of custom parts. Custom aluminum casements built to match Board-approved profiles run $2,400 to $5,500 per unit. These are Coral Gables numbers, not national averages. The Board review process, the deeper rough openings, and the marine-grade material requirements all push this market higher than inland South Florida.

FAQs - Window Replacement in Coral Gables
Yes. Every exterior window or door replacement in Coral Gables must clear both Miami-Dade County’s HVHZ product approval and the City of Coral Gables Board of Architects, regardless of NOA status. The Board reviews the unit’s profile, material, finish, and muntin pattern against the city’s 1920s Mediterranean Revival standards. A window can be fully NOA-certified and still be rejected for frame width or a muntin pattern that conflicts with the home’s original character. We handle the Board submittal before ordering so you never buy a unit that won’t pass. Call (954) 507-3613 to get your openings evaluated.
The Board of Architects consistently rejects standard white vinyl units because the frame profile and finish don’t match the Mediterranean Revival aesthetic that governs exterior changes in the city. Vinyl frames are typically wider and visually heavier than the slender original steel or wood profiles. The Board expects replacements to echo the character of the original windows, which means aluminum, thermally broken aluminum, or restored steel in most cases. We quote manufacturer lines that meet Board expectations so you’re not gambling on a rejection.
The 1920s-1940s Mediterranean Revival walls are thicker than modern construction, which means the rough opening depths are non-standard. Standard replacement windows are built for typical frame-wall depths and won’t seat correctly without custom jamb extensions and modified flashing. Installing them anyway leaves gaps that leak during storms. We measure every opening twice and fabricate the jamb extensions as part of the job, so the unit sits tight against the masonry and the flashing seals the entire depth.
Sometimes yes, sometimes no, depending on the condition of the steel and the specific requirements of the Board. We can restore original steel casements if the frames are structurally sound, rebuilding sashes, replacing hardware, and adding structural upgrades where needed. If the steel is too far gone, we fabricate custom aluminum casements that replicate the original slender profiles and muntin patterns while carrying a Miami-Dade NOA. Either way, you keep the look and get the hurricane rating. Call (954) 507-3613 for an honest assessment of what your windows need.
Six to ten weeks is realistic in Coral Gables, and the lead time is set by Board review and manufacturer fabrication, not by labor. Board submittal and review can take two to four weeks depending on the current workload, and custom unit fabrication adds four to six weeks after approval. The price is fixed in writing before ordering, so the schedule doesn’t change the cost. If you’re planning for hurricane season, call us early. We’ll give you the real timeline, not an optimistic one.
