1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.

Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

Why Salt Air Near Biscayne Bay Dictates Your Sliding Door Spec
Every year we replace sliders on south and east elevations in Coral Gables that failed prematurely because they were built to inland specs. The salt-laden air rolling off Biscayne Bay corrodes standard aluminum frames and steel hardware within three to five years. Rollers seize. Tracks pit. Frames oxidize at fasteners. The door drags, then sticks, then leaks.
The fix isn’t a better brand name. It’s a different specification entirely: marine-grade anodized finishes, stainless or hot-dip galvanized fasteners, and hardware rated for coastal exposure. The coastal-spec job costs more upfront. The inland-spec job costs more over a decade because you replace it twice.
This is the core reality of Sliding & Patio Doors in Coral Gables. The same PGT or ES Windows unit installed a mile west in unincorporated Miami-Dade gets standard hardware. Here, we specify marine-grade. The price gap runs $400-$800 per opening depending on size and hardware count. We document the spec in your written quote so you know which version you’re buying.
Before
AfterOur Sliding & Patio Doors Services in Coral Gables
Impact Sliding Glass Doors
Every impact slider we install in Coral Gables carries a Miami-Dade Notice of Acceptance (NOA) and is matched to the design pressure of your specific opening. In Coral Gables, this is only half the battle. The Board of Architects must approve the profile, material, and finish for Mediterranean Revival compatibility. We specify units from PGT and ES Windows with period-appropriate frame depths and finishes that clear both hurdles. Simulated divided lite or true divided lite grids add cost but prevent rejection.
Sliding Glass Door Replacement
Most replacement jobs we see in Coral Gables involve original steel-framed sliders from the 1920s-1940s or early aluminum units from the 1960s-1980s. The arched rough openings common to George Merrick-era construction cannot accept stock rectangular units without extensive modification. Cutting or patching oolitic limestone (coral rock) is far more labor-intensive than standard CBS or wood-frame work. We measure the existing rough opening to the sixteenth, document the arch radius, and fabricate a custom unit or modify the opening with coral-rock matching. Either way, the price reflects the material, not a markup.
Impact French Patio Doors
French patio doors in Coral Gables face the same dual-compliance burden as sliders: Miami-Dade NOA for impact resistance, Board of Architects approval for aesthetic compliance. We source impact-rated French door systems from Therma-Tru and ECO Window Systems with hardware and grid options that pass historic district review. Hinged or sliding configurations available depending on your opening width and traffic pattern.
Screen Door Installation
Retractable and fixed screen systems for sliding and French patio doors. In Coral Gables, we specify marine-grade aluminum or composite screen frames with stainless mesh and hardware to match the coastal exposure of the primary door unit.

Trusted Brands We Specify in Coral Gables
We draw from eight manufacturer lines, specifying by what the opening requires rather than what is in stock. For Coral Gables sliding and patio doors, we most often reach for PGT and ES Windows for impact-rated sliders with coastal hardware packages, Therma-Tru for impact French door systems, and ECO Window Systems for energy-efficient configurations with Low-E glazing and low U-factor. Every unit is ordered with the finish, grid pattern, and hardware specification that matches your home’s elevation and clears Board of Architects review. We do not stock units in a warehouse and hope they fit.
Common Sliding & Patio Doors Problems We See in Coral Gables Homes
- Salt corrosion on south and east elevations. Sliders facing Biscayne Bay seize when standard aluminum frames and steel rollers oxidize. We specify marine-grade anodized finishes and stainless hardware on these exposures.
- Original steel casement hardware failure. 1930s Mediterranean Revival homes still running original steel-framed sliders experience pitting at rollers and locks. Replacement requires custom-fabricated impact units sized for arched coral-rock openings.
- Board of Architects rejection of non-traditional profiles. Exposed nail-fin flanges, non-standard grid patterns, or white aluminum finishes on historic elevations trigger rejection. We pre-submit specifications to avoid re-fabrication delays.
- Energy loss through single-pane original glazing. Original steel casement sliders transmit heat load directly. Modern impact-rated units with Low-E glazing and proper SHGC cut afternoon cooling demand measurably.
Florida Pays You Back
Impact sliding and patio door upgrades in Coral Gables may qualify for several incentive programs. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida provides a sales-tax exemption on impact-resistant windows and doors. The federal 25C energy credit covers 30% of product cost on qualifying units, capped at $600 per year. After installation, a wind-mitigation inspection ($75-$150) can unlock windstorm-premium credits averaging roughly 25% on the windstorm portion of your homeowner’s premium. Programs and carriers set final eligibility and amounts; we document your product specifications so you have what you need to apply.
We Also Serve Cities Near Coral Gables
Our crews run regular routes to Coral Gables and neighboring communities including Hialeah. The same Haven Standard governs every installation, though local requirements differ: Hialeah does not maintain a Board of Architects review, so impact units with valid Miami-Dade NOA clear permitting without the aesthetic compliance layer that defines Coral Gables work.

FAQs - Sliding & Patio Doors in Coral Gables
No. The Board of Architects will reject standard white aluminum impact sliders on historic elevations even with a valid Miami-Dade NOA. Period-appropriate finishes, frame profiles, and grid patterns are required. We pre-submit specifications to the Board before ordering your unit to avoid rejection and re-fabrication delays. Call (786) 400-2761 to review your elevation and options.
Salt-laden air from Biscayne Bay corrodes standard aluminum frames and steel hardware within three to five years on south and east elevations. You need marine-grade anodized finishes and stainless or hot-dip galvanized fasteners, which add $400-$800 per opening. The coastal-spec job costs more upfront. The inland-spec job fails and gets replaced. Call (786) 400-2761 and we will specify the correct hardware package for your exposure.
Arched rough openings on 1920s-1940s Mediterranean Revival homes in Coral Gables require custom-fabricated impact units or extensive coral-rock modification. Stock rectangular units will not fit. Custom fabrication adds 4-6 weeks to lead time and $1,500-$3,500 to the installed price depending on arch radius and opening size. We measure the arch radius to the sixteenth and document it in your written quote. Call (786) 400-2761 to schedule measurement.
Yes. Impact-rated sliding glass doors with a valid Miami-Dade NOA, properly installed and documented, qualify for wind-mitigation credits.

The 25C federal energy credit and Florida sales-tax exemption may also apply. We provide the product documentation you need. Call (786) 400-2761 to discuss your specific situation.
The coastal-spec job uses marine-grade anodized finishes, stainless or hot-dip galvanized fasteners, and hardware rated for salt-air exposure. The inland-spec job uses standard finishes and hardware.
