We’re Groundwork Construction Co. of South Florida, and we know Key Biscayne’s building realities firsthand. The island’s barrier position means every exterior opening faces Atlantic salt spray and hurricane-force wind loads that mainland Miami doesn’t match. Our crews schedule deliveries around causeway traffic windows and spec stainless hardware as standard, not an upgrade. Whether you’re updating a 1960s concrete-block home off Crandon Boulevard or replacing corroded sliders in a Harbor Drive waterfront property, we bring the HVHZ expertise and brand options your project demands.
Why Groundwork Construction Co. of South Florida Is Key Biscayne’s Preferred Windows & Doors Company
Raymond Estevez built Groundwork on the principle that homeowners deserve one accountable contractor across every project phase. In Key Biscayne, that means a single team handling your window replacement, door installation, and any related exterior work without the coordination gaps that plague multi-contractor jobs. You choose the brand, we handle the build.
We’ve worked in ZIP 33149 long enough to know the local inspection rhythms, the Miami-Dade NOA product list, and the reality that a tropical storm watch can shut down the Rickenbacker Causeway with zero notice. Our bids account for this. We don’t promise timelines we can’t keep.
Homeowners across the island, from the original neighborhoods near the Village Green to the oceanfront towers along Crandon Boulevard, call us back for additional projects. That repeat business is our reputation.
Our response time to Key Biscayne typically runs same-day or next-day for consultations. We don’t keep island residents waiting while mainland contractors figure out causeway logistics.
Our Windows & Doors Services in Key Biscayne
Window Installation
New window installation in Key Biscayne demands HVHZ-rated products with Miami-Dade NOA certification, full stop. The island’s position in the High-Velocity Hurricane Zone means standard Florida Building Code windows don’t pass muster here. We install Andersen, Pella, Marvin, and Milgard product lines with proper wind-load engineering, and we handle the permit documentation that mainland crews often fumble. For homes in FEMA AE zones near the bay, we also coordinate raised sill heights with your finished-floor elevation.
Door Installation
Entry doors on Key Biscayne take a beating. Salt air attacks hinges, threshold fasteners, and lockset internals within months if you spec standard hardware. We install Jeld-Wen, Simonton, and CGI entry systems with stainless-steel or hot-dip galvanized hardware as baseline, not upsell. For homes off Harbor Drive and Mashta Drive with direct bay or ocean exposure, we recommend fiberglass or clad-wood doors over raw steel, which can surface-rust even behind paint.
Window Replacement
Key Biscayne’s housing stock tells a story: pre-1992 homes often have original aluminum single-hungs with failed seals and zero impact resistance, while post-Andrew rebuilds may have dated vinyl that’s chalking from UV exposure. A typical window replacement in Key Biscayne runs $4,500-$15,000 depending on opening count and product tier. We recently replaced a homeowner’s aging sliders on Harbor Drive with impact-rated sliding glass doors. The old tracks had corroded so badly that the doors wouldn’t budge; we swapped in stainless steel hardware and nylon rollers, and added a corrosion inspection to the package.
Impact Windows & Doors
Impact windows aren’t optional luxury in Key Biscayne; they’re code. Every replacement or new installation must use HVHZ-approved impact systems. We work with PGT and CGI for aluminum-framed impact products, and Andersen A-Series and Marvin Coastal for architectural-grade options. Impact window installation in Key Biscayne typically runs $8,000-$25,000 for a full-home retrofit. The investment replaces the need for hurricane shutters on those openings, which matters when you’re scrambling to protect a home with no mainland evacuation route.

Trusted Brands We Service in Key Biscayne
Our Windows & Doors team works with eight recognized manufacturers: Andersen, Pella, Marvin, Milgard, Jeld-Wen, Simonton, PGT, and CGI. This range covers everything from cost-effective vinyl replacements to architectural-grade aluminum impact systems. We don’t push proprietary lines or lock you into a single vendor. For Key Biscayne’s salt-air environment, we typically steer homeowners toward fiberglass or aluminum-clad products with stainless hardware packages, and we stock common replacement parts locally to avoid causeway-delayed callbacks.
Common Windows & Doors Problems We See in Key Biscayne Homes
- Corroded sliding door tracks and rollers. Salt mist penetrates standard steel rollers and aluminum tracks within 2-4 years on oceanfront properties. We replace with stainless steel or polymer rollers and anodized track systems, then schedule annual lubrication inspections.
- Failed window seals and fogged IGUs. The thermal cycling between Key Biscayne’s humid 90°F summer days and air-conditioned interiors stresses insulated glass units. Coastal homes see seal failure 30-40% faster than inland equivalents. We replace with warm-edge spacer systems where budget allows.
- Hardware seizure on exterior French and entry doors. Standard zinc-plated hinges and locksets oxidize in salt air, causing binding and eventual failure. We spec marine-grade stainless or bronze hardware on all coastal installations.
- Pre-Andrew homes lacking impact-rated openings. Many 1960s-70s concrete-block homes off Crandon Boulevard and Harbor Drive still have original jalousie or single-pane windows. Full replacement with HVHZ impact systems is technically a retrofit, not maintenance, and requires engineered anchoring into existing concrete block.
Pricing for Windows & Doors in Key Biscayne, FL
Key Biscayne’s dual compliance burden, HVHZ plus FEMA flood zone, adds cost that mainland Miami doesn’t face. Engineering, permit fees, and stainless hardware packages are real line items.

FAQs - Windows & Doors in Key Biscayne
Garage door springs in Key Biscayne typically fail in 3-5 years, half the inland lifespan, due to salt-air corrosion at the coils and loss of temper. We spec galvanized or coated springs with stainless cable assemblies and recommend annual tension checks. Call (844) 665-0162 to add a spring inspection to your next service.
Marine-grade 316 stainless steel or silicon bronze hardware is the only sensible choice for exterior doors in Key Biscayne’s salt-air environment. Standard zinc-plated or brass hardware surface-corrodes within 12-18 months. We include stainless hinges, threshold screws, and lockset internals on every coastal installation.
Yes. Key Biscayne sits entirely within Miami-Dade County’s High-Velocity Hurricane Zone, which mandates HVHZ-approved impact-resistant openings for all new construction and most replacements. Non-impact windows won’t pass inspection. We source only Miami-Dade NOA-approved products and handle the product approval documentation.
Absolutely. Standard steel rollers and untreated aluminum tracks corrode and seize in 2-4 years on Key Biscayne properties with ocean or bay exposure. We install stainless steel or polymer rollers, anodized or stainless track systems, and recommend annual lubrication with marine-grade grease. The upfront hardware upgrade costs 15-25% more but eliminates callback failures.
Pre-season preparation means verifying all impact-rated openings are intact and functional, clearing balcony drains to prevent water intrusion during wind-driven rain, and confirming sliding door tracks aren’t seized when you need to secure the home quickly. We offer pre-season inspection packages that check hardware, seals, and operation. Call (844) 665-0162 to book before June 1.
