Sliding glass door replacement in Coral Gables typically runs $2,500 to $5,000 per opening for impact-rated units that pass both Miami-Dade NOA testing and the city’s Board of Architects review.

If you’re dealing with a corroded track, a door that skips off its rollers, or visible water staining at the sill, call us at (239) 310-4121 and we’ll send a tech who knows Coral Gables homes down to the studs. We’ve been fixing and replacing sliders here long enough to know that nothing in this city is ever a simple swap.
Why Winslow Windows & Doors Is Coral Gables’s Preferred Sliding Glass & Patio Doors Company
Ed Winslow’s name is on the door – and on every job we do. That matters in Coral Gables, where homeowners have been burned by crews that show up once, pull a permit, and disappear when the Board of Architects flags the design. We don’t do that. Our Sliding Glass & Patio Doors team is led by Ed himself, and he reviews every Coral Gables job before we order a single unit. We know the Biltmore section, the Coco Plum area, the University of Miami-adjacent neighborhoods, and the historic streets off Alhambra and Granada where the review board takes an active interest in every opening you touch.
Coral Gables customers call us because we answer the phone with a live person, 24/7. Not a call center in another state. Not a voicemail that gets returned next week. A real dispatcher picks up, schedules your measure, and gets a tech out to your house. Every technician who shows up in Coral Gables is background-checked and arrives in uniform, so you know exactly who’s at your door before the truck stops rolling.
We’ve been in business since 2011, locally owned and owner-operated. Our published address and license number are on every estimate. No shell companies, no white-label subcontractors. And every job is backed by the Done Right Promise: if it’s not done right, Winslow makes it right – period. That’s a standard of accountability written into every job.
Our Sliding Glass & Patio Doors Services in Coral Gables
We specialize in the work that Coral Gables actually demands – not the generic slider swaps you’ll get from a big-box retail installer. Here’s what we do most often in the Gables:
Impact-Rated Sliding Glass Door Replacement
Coral Gables sits in Miami-Dade County’s High Velocity Hurricane Zone, which means any new sliding door must carry an NOA (Notice of Acceptance) product approval. We install impact-rated sliding doors from PGT, CGI, and Therma-Tru that meet the strictest design pressure requirements in the nation. If your current slider is a non-impact unit from the 1990s or earlier, it’s almost certainly not protecting your home the way Miami-Dade code demands today. We handle the full replacement: measure, order, permit, install, and the final Board of Architects approval package when your property falls under historic review.
Patio Door Reframing and Waterproofing
In Coral Gables, the wall around an old slider is rarely in good shape. Coral-rock and clay-tile walls from the 1920s and 1930s settle, spall, and hide water damage behind the stucco. When we open the wall around a patio door in the Gables, we consistently find failed waterproofing, undersized headers, or corroded anchors. Our reframing process is inspection-first: we open the wall, assess what’s actually there, write allowances into the contract before we begin, and get your written approval before any change order touches the final price. That’s the difference between a quote that holds and one that doubles after demo day.
Arched and Custom-Open Sliding Doors
George Merrick didn’t design rectangular openings. Coral Gables is saturated with 1920s-1950s Mediterranean Revival homes, and their arched window and door openings require fully custom-fabricated units – not off-the-shelf rectangular replacements. We work with manufacturers who cut true arched sliders and radius-top panels that fit the original opening without squeezing a square door into an arched hole. If your Gables home has an arched patio opening, don’t let anyone sell you a rectangular slider with a filler panel above it. The Board of Architects will reject it, and honestly, it’ll look wrong anyway.
Roller, Track, and Lock Hardware Repair
Salt air from Biscayne Bay attacks untreated aluminum tracks and hardware within 5-7 years. We replace corroded rollers, adjust sagging panels, rebuild weep-hole hardware, and restore smooth operation on existing sliders when a full replacement isn’t warranted yet. If the panel binds when it gets warm, or you have to lift and shove to get it moving, the rollers are probably shot. We stock common PGT and CGI hardware for Coral Gables homes so we can often repair same-visit rather than ordering parts and coming back.

Trusted Brands We Service in Coral Gables
We’re authorized installers for PGT, CGI, Mr-Glass, Therma-Tru, among others. Why does that matter in Coral Gables? Because the city’s Board of Architects routinely rejects impact windows and doors in historic districts when the frame profile or simulated divided light (SDL) muntins are too thin or flat-profile. The standard SDL bars that sail through permitting in Kendall or Hialeah get flagged here. We know which PGT and Therma-Tru configurations have already cleared review in Coral Gables historic neighborhoods, and we spec raised, thick-profile SDL bars that approximate the original Mediterranean Revival glazing bars closely enough to win approval. We also stock local parts for Coral Gables customers, so weatherstripping, rollers, and handle sets arrive faster than shipping from a warehouse in Texas.
Common Sliding Glass & Patio Doors Problems We See in Coral Gables Homes
- Corroded tracks and weep-hole hardware from Biscayne Bay salt air. Within 5-7 years, untreated aluminum tracks start to pit and chalk. Water that should drain through the weep holes gets trapped inside the sill frame, and the panel starts to stick or grind. By the time you see staining on the interior drywall, the framing underneath is usually involved.
- HVHZ doors that fail Board of Architects review. A sliding door can have the right NOA and still get rejected in Coral Gables if the frame profile, screen track, or SDL bar doesn’t match the original opening proportion. We’ve seen approved products get denied because the muntin profile was too flat. Contractors who don’t work in the Gables regularly don’t know this, and their clients pay for it in delay after delay.
- Settling coral-rock and clay-tile walls causing binding panels. Older Gables homes settle. An off-the-shelf slider installed without a full jamb inspection can bind within one season because the opening isn’t square anymore. Our install is always inspection-first and custom-shimmed – we don’t force a straight frame into a crooked wall.
- Failed waterproofing behind the original stucco. When we open the wall around a 1950s patio door, we regularly find the original flashing is gone, the felt is disintegrated, or there was never a proper sill pan to begin with. In the Gables, that means water has been finding its way into the framed sill for decades. We rebuild the waterproofing envelope before the new door goes in, not after it starts leaking again.
Pricing for Sliding Glass & Patio Doors in Coral Gables, FL
Here’s what you’re looking at in Coral Gables right now. A standard impact-rated sliding glass door (PGT or CGI, single opening, standard size) runs roughly $2,500 to $3,500 installed. Larger or custom openings with arched tops or non-standard geometry push into the $4,000 to $5,000 range. If we’re reframing the opening because the coral-rock jamb has spalled or the original header is undersized, expect another $800 to $1,500 depending on what the wall reveals. The whole-home package – replacing every slider and window in a 3/2 Mediterranean Revival – typically lands between $8,000 and $25,000 depending on opening count, floor height, and frame material.
Every quote starts with a free in-home measure. We don’t price openings sight-unseen, and we won’t give you a number over the phone that we have to walk back later. Call (239) 310-4121 and we’ll send a tech to measure, inspect the jambs, and give you a written line-item quote. Fixed pricing, no change orders without your written approval.
What Sliding Glass & Patio Doors Costs in Coral Gables
Impact windows as a category generally run $800 to $1,500 per window installed in South Florida, but sliding glass doors are a different animal entirely. A single impact-rated slider is a structural opening – it’s wider, it carries more wind load, and it has to meet Miami-Dade HVHZ design pressure requirements that a standard window doesn’t. In Coral Gables specifically, you’re also paying for the Board of Architects approval package on historic properties and the custom fabrication that arched or non-standard openings demand. Here’s the breakdown:
- Standard impact sliding door, 6-foot opening: $2,500-$3,500 installed
- Large opening (8-10 feet) or multi-panel: $3,500-$5,000 installed
- Arched or custom radius-top slider: $4,000-$5,500 installed
- Reframing and waterproofing (when the jamb is compromised): $800-$1,500 per opening
- Whole-home package (all windows and sliders): $8,000-$25,000+, depending on count and wind zone
The biggest movers on price in Coral Gables are opening count, wind zone (homes closer to Biscayne Bay carry higher design pressure requirements), floor height, and whether the Board of Architects has jurisdiction over your property. Frame material matters too: anodized aluminum is the standard for coastal salt-air exposure, and it costs a bit more than the vinyl you might see quoted in inland towns. We make it simple: free in-home measure, a written quote with every line item broken out, and no surprises on the invoice. Call (239) 310-4121 to schedule yours.
Florida Pays You Back
If you’re replacing sliders in Coral Gables, you should know what’s available before you pay full freight. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact-rated sliding doors count. Florida also exempts impact-resistant windows and doors from sales tax – that’s a real savings on a $4,000 door. The federal 25C energy credit covers 30% of the product cost up to $600 per year on qualifying energy-efficient units. And after you complete the work, a wind-mitigation inspection (typically $75-$150) can qualify you for windstorm premium credits that average around 25% on the windstorm portion of your policy. We don’t set the numbers – your insurer and the state do – but we’ll point you to the right forms and inspections so you’re not leaving money on the table.

FAQs - Sliding Glass & Patio Doors in Coral Gables
Coral Gables is the only municipality in Miami-Dade where sliding glass door replacements on historic homes must clear both Miami-Dade HVHZ NOA product approval and a separate aesthetic review by the city’s Board of Architects. The NOA proves the door meets structural wind-load standards; the Board review ensures the frame profile, SDL bars, and overall proportion match the original Mediterranean Revival character of the home. No other city in the county – not Kendall, not Hialeah, not South Miami – has this dual gate. We handle both: we order doors with NOA documentation in hand and prepare the Board submittal package so your project doesn’t stall in review. Call (239) 310-4121 and we’ll walk you through it.
Yes, and we do it regularly in Coral Gables. Arched patio openings require fully custom-fabricated sliding door units – a standard rectangular door with a filler panel will not pass Board of Architects review in historic districts. We work with manufacturers who build true radius-top and arched sliders matched to your existing opening geometry. On Santa Maria Street in the Biltmore section, we replaced a corroded 1960s aluminum slider with a PGT 7500 Series impact-rated sliding door. The original coral-rock jamb had hidden spalling behind the stucco, so our retrofit plan included custom-fabricated aluminum sub-framing and an epoxy-set anchoring pattern that kept the Big 4 anchor count above Miami-Dade’s design pressure requirement for the north-facing opening. Your home deserves the same level of care.
When we open the wall around an old patio door in a 1920s-1950s Coral Gables home, we consistently find outdated or deteriorated flashing, failed waterproofing, undersized or damaged framing, and sometimes hidden spalling in the coral-rock or clay-tile jamb. That’s the single biggest reason a remodel quote moves. The old door was installed before modern sill-pan and flashing standards existed, and decades of water intrusion have done quiet damage. Our process is inspection-first: we open the wall, assess what’s actually there, write allowances into the contract before any work begins, and price any surprise in writing before we touch it. Your quote doesn’t move after the walls are open – because we already planned for what we’d find. Call (239) 310-4121 for an exact quote; estimates are free.
Usually not. The Board of Architects in Coral Gables routinely rejects SDL bars that are too thin or flat-profile – the standard bars that pass in Kendall or Hialeah get flagged here. They want raised, thick-profile muntins that approximate the original Mediterranean Revival glazing bars. We spec the configurations that have already cleared Coral Gables historic review, and we can tell you before you order whether your door will pass. That’s local knowledge that only comes from working in the Gables year after year.
Homes closer to Biscayne Bay in Coral Gables – think Coco Plum, Hammock Oaks, and the streets off Old Cutler – deal with salt-air corrosion that inland Miami neighborhoods simply don’t see. Untreated aluminum tracks and weep-hole hardware fail within 5-7 years, causing sticking panels and hidden water intrusion into the framed sill. We recommend anodized aluminum frames with correctly oriented weep holes and marine-grade hardware on every Gables slider we install. The material choice matters as much as the install.
No. Our contract includes allowances for the conditions we expect to find when we open the wall – corroded jamb anchors, failed waterproofing, undersized headers, all the things Coral Gables homes throw at us. If we find something beyond those allowances, we stop and get your written approval before we spend a dollar. Fixed pricing, line-item quotes, no change orders without your signature. The price we quote is the price you pay. Call (239) 310-4121 to schedule your free estimate today.
