AfterConstruction Services in Key Biscayne, FL
Key Biscayne construction work has two realities most mainland contractors never think about until the job stalls: one bridge on, one bridge off, and a building code that rejects materials stamped “Florida approved” if they lack Miami-Dade’s NOA. If you’re planning a remodel, roof replacement, or addition at 33149, you need a crew that already knows how permits, deliveries, and materials work on the island. Barrett & Sons Construction has been owner-operated since 1998, with Tom Barrett and his sons running the crews. Call (877) 610-1318 and a live person answers, any hour, any day.

Why Key Biscayne Homeowners Choose Barrett & Sons Construction
We have remodeled and built across Key Biscayne long enough to know that the Rickenbacker Causeway changes everything. A missed delivery isn’t a two-hour delay; it’s a full day lost to bridge traffic and re-scheduling. Homeowners in the Harbor Drive and West Wood Drive areas have seen us plan around that, not react to it. The same goes for the Village of Key Biscayne and the Mashta Island stretch. Our reputation is built the old way: Tom Barrett publishes his name, address, and license number, and a live person answers the phone 24/7. We’re insured and bonded, and every completed job carries the written 90-Day Done Right Promise. If something isn’t right, one call brings Tom back.
Construction Services We Offer in Key Biscayne
Kitchen Remodeling
A Key Biscayne kitchen has to survive salt air and humidity while meeting HVHZ requirements for any window or exterior wall change. We plan cabinet layouts, Cambria or KraftMaid finishes, and ventilation so the remodel holds up past the warranty. Learn more about our Kitchen Remodeling in Key Biscayne.
Bathroom Remodeling
Bathrooms here face standing-water risk and elevated moisture year-round. We specify marine-grade hardware and proper exhaust so mold doesn’t move in behind the tile. Learn more about our Bathroom Remodeling in Key Biscayne.
Roofing
Key Biscayne sits inside Miami-Dade’s High Velocity Hurricane Zone, so every shingle, underlayment, and fastener must carry an NOA. We install GAF and CertainTeed systems that meet that bar and survive the next storm. Learn more about our Roofing in Key Biscayne.
Windows & Doors
Windows & Doors - Key Biscayne aren’t optional here; they’re law. We install Andersen and Marvin products with Miami-Dade NOAs already in hand, so your permit submittal doesn’t stall at the building department.
Fence Installation
Salt spray eats standard fasteners fast. We use coated hardware and materials chosen for coastal service, and we’ll set posts deep enough to handle tropical weather.
Driveway & Pavers
Flood zones mean your paver base and drainage have to work together, not against each other. We install Techo-Bloc and Belgard systems with proper pitch and compaction for Key Biscayne’s water table.
Home Additions & ADU
Additions here mean elevated slabs, flood-vented crawl spaces, and mechanicals above base flood elevation. We pull permits on every eligible job and manage inspections to sign-off.
Neighborhoods We Serve in Key Biscayne
We work all over the island. Most calls come from these areas:
- Harbor Drive
- West Wood Drive
- Mashta Island
- The Village of Key Biscayne
- Ocean Lane Drive
Response time for estimates anywhere on the island is typically one to two business days.
Why Key Biscayne’s Climate & Housing Affect Construction
Key Biscayne is a true barrier island, reachable only by the Rickenbacker Causeway, so every concrete truck, lumber flatbed, and dumpster crosses a single toll bridge. That’s a logistical chokepoint no mainland Miami contractor faces. The whole island sits inside Miami-Dade’s High Velocity Hurricane Zone, the strictest building-code designation in the country. Every window, door, our Roofing in Key Biscayne system, and fastener must carry a Miami-Dade Notice of Acceptance, a separate product approval beyond standard Florida state approval. We’ve seen contractors from Broward show up with materials stamped “Florida Product Approved” only to have Key Biscayne permitting reject the submittal. A product without the NOA isn’t legal to install here, and the re-delivery over the causeway costs a full schedule cycle.
Hurricane Andrew hit Key Biscayne directly in August 1992 and destroyed or badly damaged a large share of single-family homes. Most of the current housing stock dates from 1993 to 2008, built post-Andrew with concrete block, hip roofs, and impact-rated openings. The older oceanfront high-rises from the 1960s and 70s are a different story: decades of salt spray have accelerated chloride-induced rebar corrosion in their concrete structures, and any renovation there means dealing with hidden spalling and repair work behind the finishes.
Pricing for Construction in Key Biscayne
Honest numbers, because you should know what the island adds to a bid before you sign. Here are ranges for common Key Biscayne projects:

FAQs About Construction in Key Biscayne
Yes. Key Biscayne sits inside Miami-Dade’s High Velocity Hurricane Zone, and every window, door, and roofing product must carry a Miami-Dade Notice of Acceptance on top of Florida Product Approval. If a contractor quotes you a product without the NOA, your permit will be rejected, and you’ll lose time and money reordering. Call (877) 610-1318 if you want a second opinion on a written estimate; the second look is free.
Most Key Biscayne Kitchen Remodeling - Key Biscayne projects run $35,000-$85,000, with the biggest swings coming from cabinet grade, appliance packages, and whether you’re touching structural walls. We give you a written line-item quote, and any scope change comes as a written change order before work proceeds. Call (877) 610-1318 to schedule your free estimate.
Not unless you change the scope. Our contracts put every allowance and price in writing up front, and any change order is signed before a nail moves. An allowance that isn’t on paper is a surprise waiting for a date. If you have an estimate from someone else, we’ll review it for free.
Every eligible job includes permits pulled and inspections signed. Key Biscayne’s building department is strict, and the permit inspector works for you, not for me. We schedule the inspections, walk them with the inspector, and don’t call the job done until sign-off is in hand.
Plan for four to eight months from permit to final inspection, depending on elevation requirements, structural design, and material lead times. Flood-zone rules on the island mean elevated slabs or pier foundations and flood-vented crawl spaces on virtually every addition. We’ll give you a written timeline before you sign, and any slippage is communicated the day we know, not when you chase us down.
Yes. We’ve corrected plenty of island work where the previous contractor skipped permits or used non-NOA materials. Tom’s policy is direct: if we repair it, it carries the same 90-Day Done Right Promise as our full builds. Call (877) 610-1318 and describe what you’re seeing; if you’re in the county, there’s no trip charge.

What Key Biscayne Customers Say
"Addition over the garage matched the original roofline and brickwork so closely that visitors do not realise it was added. He tracked down the closest brick he could find rather than settling."
- Gideon Stroud"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool"His sons run the crews and they were in our house for four months. Not once did I feel I had to be home to keep an eye on things."
