Fast, Reliable Window Installation Across Coral Gables
Window installation in Coral Gables costs between $800 and $2,400 per opening for impact-rated replacement units, with full-home Mediterranean Revival restorations typically running $18,000 to $45,000 depending on historic-review requirements and framing condition. Most straightforward replacements take one to two days on site, but Coral Gables adds a wrinkle most other South Florida cities don’t: the Certificate of Appropriateness process, which can add four to eight weeks to the calendar before a single pane comes out. Our crews know both sides of that process, and we’ve been through it enough times on enough Merrick-era homes to tell you exactly what to expect. Call (954) 280-4413 and we’ll walk you through it over the phone, same day.
We’re TruePane Windows & Doors, and we’ve spent years working the tree-lined streets between Granada and Old Cutler, from Cocoplum to the Biltmore District. The bones of this city are different from anywhere else in Miami-Dade. Coral-rock walls are harder than CBU. Arched masonry openings rarely match modern rough-opening dims. And the Board of Architects will notice if you try to sneak a simulated divided-lite grid onto a 1930s wood casement. That’s not a knock on the Board. It’s a fact of doing honest work here.
Why TruePane Windows & Doors Is Coral Gables’s Preferred Window Installation Company
We’ve been called back to Coral Gables homes since 2008 of combined company heritage and community service, and the reason is the same every time: we file the paperwork right and we set the pane true. Dale Kessler founded this company in 2008 on a rule that still hangs on the shop whiteboard: if the pane is not true, the job is not done. That standard applies whether we’re installing a single awning window on a canal-front cottage off Le Jeune or a full Window Installation package on a contributing Biltmore Section estate.
Our Coral Gables customers tend to be the ones who read the fine print. They’ve lived in their homes for twenty or thirty years. Some of them had a window replaced fifteen years ago by a crew that left the sill pan unsealed and never registered the manufacturer warranty. They call us because they want a written line-item quote, both warranty layers registered in front of them, and a workmanship guarantee that doesn’t evaporate after the check clears. That’s our Done Right Promise, backed by The Keystone Standard. We’ve never had to argue it with a Coral Gables homeowner.
When you call us, a live person answers. Not a phone tree, not a callback form, not a regional center in another state. You’ll reach a person who can speak to Coral Gables specifics: how long the HPB review calendar is running right now, which manufacturers have current Miami-Dade NOAs for divided-light casements, and whether the Board is flagging recent submittals for muntin width or finish color. Dispatch and scheduling are coordinated from our Miami office, and crews reach most Coral Gables addresses within a single business day for estimates.
Our Window Installation Services in Coral Gables
Every window we install in Coral Gables carries a valid Miami-Dade County Notice of Acceptance for large-missile impact and pressure cycling. That’s the law here, and we don’t install anything less. But for Coral Gables specifically, the second approval layer matters just as much. We’ll help you navigate both. These are the window types we install most often in Coral Gables:
Casement Windows
Casement windows are the workhorses of Mediterranean Revival architecture, and Coral Gables has thousands of them, original steel casements from the 1920s and 1930s slowly rusting out in the salt air. Replacing them properly means working with the Board of Architects on divided-light profiles that match the original fenestration. We currently recommend Andersen E-Series and PGT casements for historic-district submittals, because both lines offer true divided lite options and custom exterior finishes in the bronze and dark tones the HPB typically approves for Spanish Colonial and Mediterranean homes. A casement replacement in Coral Gables runs $1,100 to $2,200 per opening depending on size and historic-review scope.

Double Hung Windows
Double hungs show up on newer Coral Gables construction and on the 1940s and 1950s ranch-style homes west of Douglas Road, toward the Riviera and Flagler Grove areas. The challenge in Coral Gables isn’t usually the product. It’s the jamb. Framing in these houses settled decades ago, and a standard double-hung retrofit can leave a racked rough opening that binds in July. We measure every opening twice and specify accordingly. Coral Gables double-hung installations typically run $900 to $1,900 per opening with full NOA compliance.

Awning Windows
Awning windows are common on Coral Gables outbuildings, pool houses, and along covered walkways on Spanish Colonial homes. They hinge at the top and shed rain well, which matters during the afternoon thunderstorms that roll in off Biscayne Bay from June through October. The salt-air exposure near the waterfront means the hardware needs to be stainless steel or coated, not plated zinc. We see zinc hardware failure constantly on canal-front homes along the Gables Waterway and in Tahiti Beach. Awning windows in Coral Gables run $800 to $1,500 per unit installed.

Fixed & Picture Windows
Fixed and picture windows on Coral Gables homes are often oversized, arched, or both, and those are the ones the HPB looks at hardest. A large fixed window on a front elevation facing Alhambra Circle or Granada Boulevard is a visual centerpiece of the facade, and the Board will review the divided-light pattern, frame profile, and exterior color before anything is ordered. We’ve filed enough of these to know what typically passes and what gets sent back. Fixed window installations in Coral Gables run $700 to $1,800 per opening, plus any custom-grid tooling the historic review requires.

Trusted Brands We Service in Coral Gables
TruePane is an authorized installer for more than a dozen manufacturer lines, and we quote them side by side on paper so you can see the actual difference in glass package, frame construction, and warranty duration. For Coral Gables historic-district work, we frequently recommend CGI, ES Windows, and CWS because their product lines include the true divided lite, custom finish, and large-missile NOA configurations the Board of Architects expects to see on contributing structures. We maintain local stocking relationships that keep most replacement hardware and sealants available without waiting on a distribution center.
Common Window Installation Problems We See in Coral Gables Homes
- Simulated divided lites rejected on contributing structures. The HPB regularly flags submittals that swap a simulated divided-lite grid for true divided lites on pre-1940 wood or steel casements. Resubmittal adds another 45 days to the review calendar. We specify the correct grid type before filing, not after.
- Salt-air corrosion on canal-front aluminum frames. Homes along the Merrick-era waterways and immediately inland from Biscayne Bay lose aluminum frame integrity far faster than properties even two miles west. White corrosion rot at the sill and hardware seizure are the usual signs. Replacement frames need marine-grade finishes and stainless hardware.
- Open sash holes left waiting for historic approval. Some crews tear out the old windows and then wait for the Board to approve the replacement, leaving the house open to afternoon thunderstorms that can soak subfloors and drywall. We file first, get the Certificate in hand, and only then schedule tear-out day.
- Standard impact windows that pass NOA but fail COA. Miami-Dade product approval is not the same as Coral Gables architectural approval. A window can carry a perfect NOA file and still get rejected for the wrong muntin bar width or exterior finish. We check both before the order is placed.
Pricing for Window Installation in Coral Gables, FL
Here is what we see in the Coral Gables market, averaged across recent jobs. A standard single-hung or casement replacement in a non-historic home runs $850 to $1,400 per opening installed. An impact-rated Andersen E-Series or PGT casement with true divided lites runs $1,300 to $2,200 per opening. A full-home replacement on a 1920s coral-rock Mediterranean with all casements and a front elevation under HPB review typically lands between $22,000 and $48,000 including the Certificate of Appropriateness submittal, any required re-glazing consultations, and full permit close-out. Yes, the historic review adds time and sometimes cost. But it is the cost of doing the job in Coral Gables the way Coral Gables requires. We give written line-item pricing before any work starts, and we stand behind the number.

FAQs - Window Installation in Coral Gables
We do. TruePane prepares and files the COA submittal packet on your behalf, including elevation drawings, product specifications, finish samples, and the manufacturer NOA documentation. Filing responsibility rests with the permit applicant, but we handle the whole packet from first measurement to Board hearing. Call (954) 280-4413 and we’ll tell you what your specific home will need.
Plan on four to eight weeks added to the calendar for Certificate of Appropriateness review on contributing structures. Non-historic homes still need the standard Miami-Dade permit path, which is faster. We file the COA first and schedule installation only after approval lands, so your home is never sitting with open sash holes waiting on a committee.
On contributing structures, true divided lites are almost always required. The Board has flagged simulated divided-lite grids as a change to the historic fenestration profile and sent applications back for resubmittal. We specify true divided lites on pre-1940 wood and steel casements before filing.
Every replacement window in Coral Gables must carry a valid Miami-Dade County Notice of Acceptance for large-missile impact and pressure cycling, regardless of whether the home sits on the water. Canal-front and bayfront homes have the same NOA requirement as interior streets, but the salt exposure makes frame material and hardware grade more critical over the life of the window.
The Merrick-era interior waterways channel salt-laden air directly over the homes facing them, and that air deposits chloride on aluminum frames, sill pans, and hardware in concentrations far above what you’d find even a mile west. It accelerates oxidation and causes the white, chalky corrosion we regularly see on canal-front homes. Proper replacement means marine-grade finishes and stainless hardware from the outset.
