The wide range reflects whether you’re replacing eight original steel casement windows in a 1920s Mediterranean Revival or installing impact-rated sliding glass doors across a renovated addition.
How We Handle Impact Windows & Doors from First Measurement to Final Walkthrough
Every impact windows and doors job in Coral Gables moves through five distinct stages. Here’s what happens, how long each takes, and what you’ll need to decide.
Stage 1: Site survey and product selection (3-5 days)
We measure every opening to the sixteenth of an inch, document existing trim conditions, and photograph the interior and exterior surrounds. At this stage, you’ll choose between aluminum or vinyl frames, laminated glass thicknesses, and finish colors. For Coral Gables homes with arched openings - common in the 1920s-1960s stock - we flag whether the original masonry arch can be preserved or must be re-formed. You’ll also decide on hardware style and whether you want integrated screens or storm shutters as backup protection.
Stage 2: Board of Architects and permitting (4-8 weeks)
This is where Coral Gables diverges from every neighboring market. We prepare drawings showing exterior elevations, frame profiles, and color samples, then submit to the Coral Gables Board of Architects for aesthetic approval before Miami-Dade building permit review even begins. The Board meets twice monthly, and revisions are common on first submission. We build this timeline into every proposal. Once Board approval clears, we file for the HVHZ permit with Miami-Dade, which adds another 2-3 weeks.
Stage 3: Fabrication and delivery (3-6 weeks)
Impact-rated windows and doors are built to order - nothing sits on a shelf for this wind-load zone. Aluminum frames from our PGT and CGI lines typically ship faster than custom Marvin or Pella architectural grades. We coordinate delivery to avoid staging materials on-site longer than necessary, especially on narrow Coral Gables lots where driveway access is tight.
Stage 4: Installation (2-5 days for most homes)
Crews remove existing units, prep openings, install new frames with HVHZ-approved anchoring, seal perimeters with backer rod and structural sealant, and reinstall or replace interior trim. Homes with oolite limestone walls require diamond-blade cutting and specialized fasteners - not standard Tapcons - which adds a day. We protect floors and furniture, and we work room by room so you’re not fully exposed overnight.
Stage 5: Inspection and finish (1-2 weeks)
Miami-Dade HVHZ inspection verifies anchoring, glazing labels, and missile-impact certification. The Board of Architects may also require a final aesthetic sign-off. We touch up interior trim paint, adjust hardware, and clean glass. You’ll receive product warranties and our installation guarantee at walkthrough.
The Product Decisions That Shape Your Installation
Impact windows and doors aren’t a single product. The choices you make here determine performance, maintenance, and how well the result fits your home’s character.
- Aluminum frames (PGT, CGI, Andersen Architectural): Strongest structural option for large openings, slim sightlines, powder-coated finishes that hold up in salt air. Costs more upfront, conducts more heat than vinyl, and may sweat in extreme humidity without thermal breaks. Best for homeowners restoring historic aesthetics or maximizing glass area.
- Vinyl frames (Simonton, Jeld-Wen, Milgard): Better insulation values, lower cost, minimal maintenance. Frame profiles are thicker, which can look heavy on smaller 1920s windows. Color choices are more limited, and dark vinyl in direct sun can warp over time. Suits budget-conscious projects and homes where energy performance is the priority.
- Laminated glass thickness (.090 PVB interlayer vs. SentryGlas Plus): Standard .090 meets HVHZ code and blocks 99% of UV. SentryGlas adds rigidity for oversized doors and clearer sightlines under load - useful for waterfront homes with panoramic sliders. Adds 15-25% to glazing cost.
- Operating style: Single-hung and casement dominate Coral Gables restorations; horizontal rollers and folding walls work better for rear additions opening to pools. Fixed picture units cost less but don’t ventilate. We match sight lines across the facade so the mix doesn’t read as patched-together.
- Integrated screens and storm shutters: Some homeowners add roll-down shutters for extra protection beyond impact glazing, especially on second stories. Others skip shutters entirely and rely on impact glass alone. This decision affects exterior trim detailing and should be made before fabrication begins.
What Impact Windows & Doors Costs in Coral Gables, FL
| Project Scope | Typical Range |
|---|---|
| Partial replacement (6-10 openings) | $8,000-$14,000 |
| Full-home replacement (15-25 openings) | $15,000-$25,000 |
| Single large impact door (sliding or French) | $3,500-$7,500 |
| Custom arched or architectural units | Add 30-50% per opening |
Five factors push any impact windows and doors job toward the high or low end of these ranges:
Opening count and size. More windows means more units, but economies of scale kick in on full-home jobs. Oversized sliders and custom shapes carry premium fabrication charges.
Existing frame condition. Rotted wood bucks, corroded steel, or compromised limestone surrounds require reconstruction before new units go in. We see this often in pre-1950 Coral Gables homes where original steel casements have rusted through.
Interior trim and wall repair. If we’re matching plaster surrounds or restoring original wood casing, finish carpentry adds labor. Drywall returns are faster and cheaper but look wrong in a 1926 Mediterranean.
Material grade and brand tier. CGI and PGT’s commercial lines cost more than their residential series. Marvin Ultimate and Pella Architect Series sit above Andersen 400 Series. You choose - we don’t lock you into one catalog.
Permit scope and Board of Architects complexity. Straight replacements in the same opening with matching profiles move faster. Additions, relocations, or profile changes trigger deeper review and potentially multiple submission cycles.
A written estimate from us includes product, labor, permit fees, and standard trim repair. It does not include interior painting, landscaping repair, or Board of Architects revision fees if redesigns are requested.
Why Coral Gables Changes Everything About This Job
Impact windows and doors here aren’t simply a matter of picking a product and installing it. The city operates its own Board of Architects - separate from Miami-Dade permitting - that must approve virtually all exterior work to enforce the 1920s Mediterranean Revival design code. Barrel-tile rooflines, stucco exteriors, arched openings, and specific color palettes aren’t suggestions; they’re requirements with teeth. This dual-approval layer adds weeks to timelines and demands contractors who’ve navigated both the aesthetic standards and the city’s unique review process, a requirement that simply doesn’t exist in neighboring unincorporated Miami-Dade or the City of Miami.
The housing stock reinforces this complexity. Most homes we work on in Coral Gables were built between the 1920s and 1960s under George Merrick’s original plan, with oolite limestone - coral rock - forming foundations and walls. Standard concrete-block repair techniques don’t apply. Diamond-blade wet cutting and hydraulic lime mortars are necessary when we encounter compromised surrounds, which is common where decades of moisture intrusion have degraded original masonry.
Climate adds another layer. Coral Gables sits fully within Miami-Dade’s High-Velocity Hurricane Zone, the strictest wind-load code in the country. Every impact window and door must carry HVHZ certification, and installers must be HVHZ-certified. The material cost premium over non-HVHZ products is real - typically 20-35% - but it’s not optional. We’ve seen homeowners in nearby Glenvar Heights or South Miami tempted by lower bids using non-certified products; those don’t pass inspection here.
Homeowners often pair impact windows and doors with exterior upgrades that require the same Board coordination. Aluminum Fence in Coral Gables and Iron Fence in Coral Gables are common companion projects, especially for pool enclosures and courtyard boundaries where the Board’s sight-line and height rules also apply.

Frequently Asked - Impact Windows & Doors in Coral Gables
From signed contract to final inspection, most projects run 10-16 weeks. The Board of Architects review accounts for 4-8 weeks of that; actual installation is only 2-5 days. Call (844) 665-0162 and we’ll map out your specific timeline based on your home’s location and scope.
Yes, and two of them: Board of Architects approval for aesthetic compliance, then a Miami-Dade HVHZ building permit for structural and wind-load verification. Both are mandatory for exterior work. We handle both filings as part of our standard process.
Almost always. Replacement in existing openings rarely touches utilities. Problems arise only when homeowners want to enlarge openings or relocate doors, which may encounter wiring in limestone walls. We flag this during the site survey before you commit.
For homes built before HVHZ codes, repair isn’t a legal option for hurricane protection - original steel casements and single-pane glass don’t meet current standards. Replacement is the only path to code compliance and insurance discounts. The investment is higher upfront but required for permitted work.
Product warranties vary by manufacturer - typically 10-20 years on frames and glass, with some lifetime coverage on hardware. Our installation workmanship is guaranteed for the period we specify in your written contract. We don’t mix third-party warranties or imply coverage we haven’t confirmed. Ask us for specifics on the brands you’re considering.
