Construction in Key Biscayne, FL
Roofing in Key Biscayne typically runs $400-$20,000 depending on whether we’re repairing salt-corroded fasteners or replacing an entire assembly after hurricane exposure, and every job must meet Miami-Dade High-Velocity Hurricane Zone standards with third-party inspection. Because the island is reachable only by the Rickenbacker Causeway, material deliveries and crew scheduling require contingency planning that mainland Miami contractors rarely encounter. Call (786) 321-4970 and we’ll deliver a written price before anyone picks up a tool.
Why Key Biscayne Homes Are Different
Key Biscayne sits on a barrier island flanked by Biscayne Bay and the Atlantic Ocean, where constant salt spray corrodes structural fasteners, rebar, and exposed metal in ways that inland construction never faces. We specify stainless or hot-dipped galvanized hardware and enforce strict concrete cover specifications to prevent spalling on every job we touch.
The housing stock tells its own story. Oceanfront and Crandon Boulevard corridors are dominated by 1960s-1970s concrete high-rise and mid-rise condominiums, many now undergoing mandatory milestone structural inspections triggered by the Surfside collapse. Single-family homes tend toward newer luxury builds or tear-down replacements, nearly all requiring elevated foundations and FEMA flood elevation certificates that add engineering and fill costs before framing begins.
Nearly the entire island maps into FEMA AE or VE flood zones at near-sea-level elevation, so base flood elevation compliance and breakaway wall design are standard requirements on almost every new build or substantial improvement. And because the Rickenbacker Causeway is the sole artery, any closure for high winds, accidents, or maintenance can strand crews and halt deliveries with no alternate route. Experienced Key Biscayne contractors build causeway-delay contingency days into contracts that Miami Beach or Coral Gables builders would never consider.
Our Main Key Biscayne Services
Most calls we field from Key Biscayne homeowners center on two needs: updating aging interior spaces and expanding footprint on tight island lots. Here’s how we approach each.
Kitchen Remodeling in Key Biscayne
Key Biscayne kitchen remodels often involve opening up closed 1970s condo layouts or reconfiguring luxury single-family kitchens to meet current HVHZ impact requirements when exterior walls are modified. We source KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, and deliver a written price before demolition starts. Every project includes a documented photo record and falls under our 365-Day Done Right Promise backed by The Haven Standard. Kitchen Remodeling in Key Biscayne

Bathroom Remodeling in Key Biscayne
Bathroom work on the island ranges from tub-to-shower conversions in older condos to full master bath rebuilds in newer homes, with moisture management critical given the salt-air environment. We specify Kohler and Toto fixtures rated for coastal corrosion exposure and quote every job flat with written scope. No change proceeds without a signed change order, the discipline that has kept our projects within a few percent of the agreed cost since 2007. Bathroom Remodeling in Key Biscayne

Home Additions & ADU in Key Biscayne
With limited vacant land and strict FEMA flood zone requirements, Key Biscayne additions often mean vertical expansion or garage conversion rather than ground-up ADU construction. We engineer for base flood elevation compliance and breakaway wall design where required, pulling permits and scheduling third-party inspections as standard. The written quote includes all engineering, fill, and elevation certificate costs upfront. Home Additions & ADU in Key Biscayne

Before
AfterRoofing in Key Biscayne

Key Biscayne’s 1960s-1970s concrete high-rises and mid-rises along Crandon Boulevard are entering a wave of mandatory structural inspections, and their flat or low-slope roofs demand assemblies that withstand both salt corrosion and HVHZ wind loads. Single-family homes, whether original builds or recent tear-downs, face the same Atlantic exposure and must meet the most stringent residential building code in the United States. We install Roofing systems with third-party inspection documentation included, and every quote is written before work starts.
Roof Repair
Signs you need it
Water stains on concrete ceiling soffits, spalling around roof penetrations, or visible corrosion on exposed metal flashings after storm season.
What it costs in Key Biscayne
Roof repair in Key Biscayne typically ranges from $400 to $1,800 depending on whether we’re patching a membrane penetration or replacing corroded flashings and fasteners.
How we do it
We photograph the full condition, remove compromised material to sound substrate, install new underlayment and finish layer, and submit documentation for any warranty or insurance claim.
Roof Replacement & Installation
Signs you need it
Multiple leak points, membrane beyond 20-year service life, or engineer-mandated replacement following milestone structural inspection findings.
What it costs in Key Biscayne
Complete roof replacement in Key Biscayne runs $8,000 to $20,000 for standard asphalt shingle assemblies, with metal and tile systems priced separately based on engineering requirements.

Yes, virtually all roofing work in Key Biscayne requires a Miami-Dade permit with third-party inspection, and we pull permits and schedule inspections as standard on every job. The permit cost is included in your written quote, not added later.
Windows & Doors in Key Biscayne

Key Biscayne’s 1960s-1970s condominiums and newer luxury single-family homes alike must meet High-Velocity Hurricane Zone requirements, meaning every window and door replacement requires impact-rated assemblies with engineered wind-load calculations and third-party inspection. The salt-air environment also demands hardware and framing rated for coastal corrosion, not standard inland specifications. We install Windows & Doors with full documentation for HOA and insurance compliance.
Impact Windows & Doors
Signs you need it
Original non-impact windows failing inspection, insurance policy requiring HVHZ-rated assemblies, or visible frame corrosion and seal failure after storm season.
What it costs in Key Biscayne
Impact window installation in Key Biscayne typically runs $8,000 to $25,000 for a full residential replacement, with per-opening costs varying by size and engineering requirements.
How we do it
We measure each opening, specify Miami-Dade-approved impact assemblies with coastal-rated hardware, install with proper shimming and fastening per engineering, and schedule third-party inspection for certificate of compliance.
Window Replacement
Signs you need it
Fogged insulated glass units, operable windows that no longer seal properly, or frames with visible salt corrosion compromising structural integrity.
What it costs in Key Biscayne
Standard window replacement in Key Biscayne ranges from $4,500 to $15,000 depending on opening count, frame material, and whether impact rating is required by code or HOA.

| Window Replacement | $4,500 - $15,000 |
Do condos in Key Biscayne allow non-impact window replacements?
No, virtually all Key Biscayne buildings require impact-rated or HVHZ-approved assemblies, and most HOAs mandate specific aesthetic and documentation standards that we coordinate before ordering material. Call (786) 321-4970 and we’ll review your building’s requirements at no charge.
How do I know if my windows are impact-rated?
Impact-rated windows carry a permanent Miami-Dade Notice of Acceptance label or Florida Product Approval marking; if you cannot locate either, we inspect and document status as part of our free estimate process.
Fence Installation in Key Biscayne

Key Biscayne’s single-family homes and select townhouse communities require fencing that withstands salt corrosion, storm surge, and strict HOA aesthetic standards, while FEMA flood zone requirements often mandate breakaway or elevated designs for perimeter structures. The island’s limited lot sizes and high property values mean fence work is precision work, with material choices that affect both durability and resale. We install Fence Installation with coastal-rated hardware and written specifications before breaking ground.
Vinyl Fence
Signs you need it
Existing wood fence showing terminal salt rot, HOA mandate for uniform white or tan perimeter fencing, or need for low-maintenance privacy screening on a tight lot.
What it costs in Key Biscayne
Vinyl fence installation in Key Biscayne typically runs $3,500 to $9,000 depending on linear footage, post depth requirements for wind load, and gate configuration.
How we do it
We locate utilities, set posts in concrete at HVHZ-specified depth with stainless hardware, hang panels and gates with proper clearance, and deliver photo record of post spacing and hardware specs.
Aluminum Fence
Signs you need it
Decorative perimeter or pool enclosure requiring corrosion resistance without the maintenance cycle of painted steel or wood.
What it costs in Key Biscayne
Aluminum fence installation in Key Biscayne ranges from $4,000 to $10,000 depending on height, picket style, and whether we’re integrating with existing masonry or installing on grade.
How we do it
We specify powder-coated aluminum with stainless fasteners, set posts with proper drainage and concrete footing, verify gate swing and latch function, and document installation for HOA or pool inspection compliance.
What Fence Installation Costs in Key Biscayne
| Item | Typical range in Key Biscayne |
|---|---|
| Vinyl Fence Installation | $3,500 - $9,000 |
| Aluminum Fence Installation | $4,000 - $10,000 |
Will my HOA approve the fence style?

Can fences be installed in FEMA flood zones?
Yes, but FEMA AE and VE zones in Key Biscayne typically require breakaway designs or elevated installations that allow floodwater passage; we engineer and permit accordingly with no change orders for compliance requirements discovered mid-project.
Driveway & Pavers in Key Biscayne

Key Biscayne’s newer luxury homes and tear-down replacements often feature extensive hardscape, but nearly every lot sits in FEMA AE or VE flood zones requiring permeable or properly drained surfaces that don’t impede stormwater flow. The salt-air environment also degrades standard concrete sealers and steel reinforcement faster than inland conditions. We install Driveway & Pavers with Belgard and Techo-Bloc systems engineered for coastal exposure and base flood elevation compliance.
Paver Driveways
Signs you need it
Existing concrete driveway cracked from settling on fill, need for permeable surface to meet stormwater management requirements, or aesthetic upgrade to match luxury home standard.
What it costs in Key Biscayne
Paver driveway installation in Key Biscayne typically runs $7,000 to $18,000 depending on excavation depth, base material requirements for flood zone compliance, and pattern complexity.
How we do it
We excavate to engineered depth, install permeable base and bedding layers, lay Belgard or Techo-Bloc pavers to pattern with edge restraint, sweep in polymeric joint sand, and compact to specification with photo documentation of base construction.
Concrete Driveways & Concrete Work
Signs you need it
Spalled or cracked existing driveway, need for elevated slab to meet base flood elevation, or new construction requiring concrete that withstands salt-air exposure.
What it costs in Key Biscayne
Concrete driveway installation in Key Biscayne ranges from $4,500 to $12,000 with proper reinforcement, vapor barrier, and coastal-rated sealer included in the written scope.
How we do it
We form to engineered elevation, place steel reinforcement with proper concrete cover for salt exposure, pour with air-entrained mix, finish to grade with drainage slope, and apply specified sealer with cure time documented.
What Driveway & Pavers Costs in Key Biscayne
| Item | Typical range in Key Biscayne |
|---|---|
| Paver Driveway Installation | $7,000 - $18,000 |

Call (786) 321-4970 for a written quote that includes all compliance costs.
How long before I can drive on a new paver driveway?
We recommend 48-72 hours before light vehicle traffic on paver installations, with full joint stabilization achieved after polymeric sand activation and initial settling; we provide written care instructions with the final photo record.
