Remodeling Company in Key Biscayne, FL
Home remodeling in Key Biscayne means working on properties that sit on a barrier island, subject to some of the strictest building regulations in Florida. We’re a general contractor serving Key Biscayne homeowners with kitchen, bathroom, and whole-home remodeling, and we put a written price and a written 365-day guarantee in front of you before any work begins. If you’re planning a remodel, call (850) 988-7559 and we’ll walk through what your project needs.
Why Key Biscayne Homes Are Different
Key Biscayne’s housing stock divides into three broad groups: luxury single-family homes built to elevated floodplain standards, mid-rise condominiums along Crandon Boulevard, and older concrete structures from the 1950s through the 1970s. Many of those older buildings still carry original aluminum wiring and single-pane jalousie windows that fail modern wind-load tests. When we open a wall in one of these units, we’re rarely surprised by what we find; the work simply has to account for it.
This is a barrier island, and the construction market reflects that. Hurricane resilience, flood mitigation, and FEMA regulations drive decisions here more than almost anywhere else in the state. Elevated foundations, impact-rated windows and doors, corrosion-resistant hardware, and moisture-resistant materials are not upgrades in Key Biscayne. They’re the baseline. High humidity adds another layer: anything we install has to stand up to salt air and sustained moisture, and we build to that standard on every project.
Permitting also moves differently here. Coastal construction requires documentation for wind load, elevation, and floodproofing that a remodel in a mainland suburb would never trigger. We handle that paperwork as part of the job, and the written price you receive includes the permits and inspections from the start.
Styles & brands we work with
Our Main Key Biscayne Services
Most Key Biscayne homeowners call us for one of three things: a full general contracting engagement, a kitchen remodel, or a bathroom remodel. Each has its own page with detailed pricing, but here’s the short version of how each works locally.
General Contractor in Key Biscayne
Acting as your general contractor in Key Biscayne means coordinating every trade, permit, and inspection on a coastal property. Remodels here frequently touch structural elements: relocating walls in a 1960s concrete condo, upgrading electrical systems that still run on original aluminum wiring, or reinforcing openings for impact-rated windows. We manage the full sequence from demolition through final inspection, and the written price you receive covers every phase. General Contractor in Key Biscayne has the full breakdown of how we run these projects.
Bathroom Remodeling in Key Biscayne
Bathrooms on a barrier island contend with constant humidity and salt air, which accelerates wear on fixtures, caulking, and substrates that would last decades inland. In older Key Biscayne condos, a bathroom remodel often becomes a moisture-correction project: pulling out drywall behind tile that was never meant for this climate and rebuilding with a proper cement board substrate. We quote the work in writing before demolition starts. Bathroom Remodeling in Key Biscayne covers the specifics.
Kitchen Remodeling in Key Biscayne
Kitchen remodeling in Key Biscayne often involves working around concrete structure and older mechanical systems. Many of the mid-century buildings limit where a sink or range can move without serious plumbing rework, which is a conversation we have early and honestly. Cabinet lines like KraftMaid and Wellborn, paired with Cambria or Silestone countertops, hold up well in this climate when installed correctly over moisture-resistant materials. Kitchen Remodeling in Key Biscayne has full pricing and process details.

Home Remodeling in Key Biscayne
Home remodeling in Key Biscayne usually means one of two things: modernizing an older condo unit in a mid-rise building, or taking a single-family home down to the studs and rebuilding it to current coastal code. Whole-house remodels on this island regularly involve elevation work, impact-rated glazing, corrosion-resistant fasteners, and floodproofing details that a mainland remodel would never encounter. The homes along Crandon Boulevard and the surrounding streets were built for a different climate era, and every renovation has to bring them forward. We quote the entire scope in writing before a single wall comes down. You can read more about our process on the Home Remodeling page.

What Key Biscayne Customers Say
"Good remodel of two bathrooms. A fixture came in wrong and added a few days, but they ate the cost of fixing it. Finish work is excellent and they cleaned up daily."
- Rudy Mackey"Redid two bathrooms at once. The crew protected the floors and cleaned up every single day before leaving. Quote was detailed and there were no mystery charges at the end."
- Tricia Dawson"Full home refresh before we sold. They were straight about what was worth doing and what wasn't to get our money back. On time, on budget, and it sold in a week."
- Monica Vaughn
