Fast, Reliable Sliding & Patio Doors Across Coral Gables
Sliding and patio door replacement in Coral Gables runs $2,800 to $9,500 for a standard impact-rated unit installed, and $12,000 to $28,000 for panoramic or custom systems that must clear the Board of Architects. Those numbers reflect a reality that does not exist anywhere else in South Florida: every exterior door in Coral Gables has to satisfy two separate authorities before it can be installed. We handle both, so you do not have to learn either process the hard way. Call (954) 507-3613 for a free estimate, and we will walk your specific opening, your specific wall, and your specific architectural constraints before any quote is written.
We schedule estimates across Coral Gables neighborhoods including the Riviera District, the Biltmore section, and streets off Alhambra Circle, Granada Boulevard, and Hardee Road. Our crews know these blocks well enough to tell you which homes have original coral rock jambs before we ever set foot inside.
Why TruePane Windows & Doors Is Coral Gables’s Preferred Sliding & Patio Doors Company
TruePane has been doing this work since Dale Kessler founded the company in 2008, and the crews serving Coral Gables today are the same ones who have spent years opening up 1920s and 1930s Mediterranean Revival walls and learning what is actually inside them. Coral Gables homeowners tend to ask sharper questions than most, and they should. This is a city where a code-compliant impact sliding door can be rejected at final review because the muntin pattern is too wide or the finish reads too modern. We have been through that process enough times to know exactly what the Board of Architects will flag before the door is even ordered.
Every Coral Gables job gets two things in writing before work begins: a line-item quote with no allowances left vague, and a warranty registration package that covers both manufacturer layers under The Keystone Standard. That means the warranty is registered before the truck leaves your driveway, not filed away at some corporate office. If something is not right within 90 days, the Done Right Promise says we make it right. No paperwork fights. No arguing about who is responsible. Dale Kessler put that rule on the whiteboard the week the company launched: if the pane is not true, the job is not done.
A live person answers our phone 24 hours a day, seven days a week. When you call about a Coral Gables slider that has seized up, you talk to someone who can schedule the service call, not a voicemail tree.
Our Sliding & Patio Doors Services in Coral Gables
Patio Sliding Doors
Standard patio sliders in Coral Gables homes fail in predictable ways: salt air eats the roller track, the sash lifts off the rail, and the seal between the glass panes breaks down within a decade. We replace these with impact-rated units that carry a Miami-Dade NOA and are ordered with finishes the Board of Architects will approve. A typical two-panel replacement with impact glass in Coral Gables runs $4,200 to $7,800 installed, depending on the rough opening and whether we need to rebuild the jamb.

Panoramic Sliding Systems
Owners of larger Coral Gables estates frequently want a wall of glass that opens to the pool or courtyard. These systems, with panels that stack or pocket fully into the wall, start around $14,000 for a three-panel configuration and go up from there. The architectural review on these is stricter because the Board of Architects scrutinizes the sightlines and frame profiles against the home’s original Mediterranean character. We order frames with thermally broken aluminum in custom bronze or anodized finishes, and we bring the NOA documentation to the review meeting before the permit is filed.

Heavy-Duty Sliding Doors
For Coral Gables homes with oversized openings, especially those facing Biscayne Bay, standard residential sliders are not enough. Heavy-duty units with reinforced frames and impact glass rated for large missile impact cost $9,000 to $18,000 in this market, depending on the width and glass package. The salt-air exposure near the bay is relentless, so we specify marine-grade anodizing on the frame and stainless steel roller assemblies. A door installed a half mile from the water needs different hardware than one on a street in the interior of the city, and we price it accordingly.

Pocket & Barn Doors
This is where Coral Gables gets particular. Many 1920s homes have original pocket doors in interior walls, and homeowners replacing exterior openings often want that same clean look on a modern sliding or patio door. Pocket and barn door installations inside a Coral Gables masonry home require cutting into walls that may be solid coral rock or structural block. A true exterior pocket pocket system for a patio opening runs $10,000 to $16,000 here, including the structural header work. We inspect the wall first, price the reinforcement honestly, and get every modification approved before the first cut.

Trusted Brands We Service in Coral Gables
We are an authorized installer for more than a dozen manufacturer lines, and for Coral Gables work we gravitate toward brands that hold current Miami-Dade NOAs and offer the narrow frame profiles the Board of Architects tends to approve. CGI and PGT carry the impact ratings for standard openings. ES Windows and ECO Window Systems offer the slim-profile, thermally broken aluminum frames that replicate the look of original steel casements, which matters on a 1929 house off Granada Boulevard. We keep common hardware, rollers, and weatherstripping for these brands on our trucks so a service call in Coral Gables does not mean two weeks of waiting on a part. When a door needs a full replacement, we quote the manufacturer lines side by side on paper so you see exactly what each option costs and what each warranty covers. This is the way Dale has run Sliding & Patio Doors since day one.
Common Sliding & Patio Doors Problems We See in Coral Gables Homes
- Salt-air corrosion on roller tracks. In homes within half a mile of Biscayne Bay, aluminum tracks corrode and the door freezes in place. The fix is usually a marine-grade roller assembly and a full track replacement, not a new door, but you need someone who can tell the difference before quoting you $6,000.
- Fog between the glass panes. Seal failure happens faster in Coral Gables than inland because the constant humidity pushes moisture into any microgap in the seal. Once the seal goes, the insulated glass unit is done; the fix is a glass replacement, not a whole new frame.
- Shallow rough openings in original coral rock walls. Homes built between 1925 and 1940 often have rough openings only 4 to 5 inches deep. Modern impact sliders need more depth. A contractor who does not check before the door is ordered will not be able to pass inspection, and you will be the one staring at a door that cannot be installed.
- Board of Architects rejection on finish or muntin pattern. We see this in Coral Gables more than any other city we serve. A homeowner buys a fully NOA-approved impact slider, the permit gets pulled, and then the architectural review flags the frame width or the grille pattern. Now the door has to come out. We do the architectural review first, every time, before any door is ordered for a Coral Gables home.

FAQs - Sliding & Patio Doors in Coral Gables
Coral Gables is the only city in South Florida where a sliding door must pass both Miami-Dade’s High-Velocity Hurricane Zone NOA review and the City of Coral Gables Board of Architects’ Mediterranean Revival design review. A door can be structurally compliant and still get rejected because the frame profile, finish color, or muntin pattern does not match the original 1920s architectural character. The Board’s aesthetic review is a separate gatekeeper, and it is binding. That is why we file the architectural submittal before ordering any door for a Coral Gables home. Call (954) 507-3613 and we will tell you upfront whether your preferred door will pass.
We open the jamb first and measure the actual rough opening depth before any door is ordered. When the wall is solid coral rock and the rough opening is only 4 to 5 inches deep, we fur out the interior to create the depth a modern impact frame needs, then use a marine-grade flashing tape to protect the new jamb from salt air. This is structural work, not a simple swap, and we price it as a line item in the original quote so there is no surprise later. The alternative, which we see too often in Coral Gables, is a contractor who notches the framing to make a standard door fit and then fails inspection. We do not cut corners in a 1938 wall that has stood for nearly a century.
We check three things in order: the rough opening depth and whether the wall is coral rock, block, or a mix; the condition of the existing waterproofing and any rot or corrosion hidden behind the stucco; and the wiring path, because older Coral Gables homes frequently have outdated electrical running through walls where a new header has to go. Any one of those can change the scope of work, and we price the quote with those checks already done so the number is honest. A contractor who quotes without opening the wall is guessing.
Yes. Every exterior sliding or patio door replacement in Coral Gables requires a city permit in addition to the Miami-Dade County product approval. The city permit process includes the Board of Architects review for homes in the historic overlay districts, which covers a large portion of the city. We pull the permits, we attend the architectural review, and we do not order a door until the written approval is in hand. That sequence saves Coral Gables homeowners from paying for a door they cannot legally install. Estimates are free, call (954) 507-3613 to schedule one.
Fogging between panes means the insulated glass unit seal has failed and moisture has entered the space between the two layers of glass. In Coral Gables, the constant humidity and salt air accelerate seal failure compared to inland Florida, especially on older aluminum-framed doors. Once the seal is gone, the glass unit must be replaced; there is no cleaning or repair that restores it. We replace the glass in the existing frame, which runs $500 to $1,300 for most Coral Gables doors, or we quote a full door replacement if the frame has also corroded to the point where a new unit makes more sense. Call (954) 507-3613 for an exact quote, and the estimate is free either way.
