Why Elmstead Remodeling Is Key Biscayne’s Preferred General Contractor Company
We’ve learned that families in Key Biscayne hire us because we treat the island’s logistical realities as part of the job, not an afterthought. The causeway closes during hurricane evacuations. Drawbridge events and accidents back up material deliveries. The Village runs its own permit counter with its own inspection queue. Our General Contractor team accounts for all of this in the schedule we present you – not in excuses we make later.
Our customers here mention the same things in reviews: shoe covers at the door without being asked, drop cloths on the travertine before a tool comes inside, and the photo we text of the clean-up before the crew leaves. The 365-Day Done Right Promise covers every completed project. If it’s not done right, we make it right. That’s stamped on every contract.
Phones are answered by a live person 24/7. No voicemail. No automated system. No waiting until Monday for a callback about your Harbor Drive condo or your Mashta Island remodel.
Styles & brands we work with
Construction Company in Key Biscayne
Construction Company work in Key Biscayne means building within constraints mainland Miami contractors rarely face: causeway-timed deliveries, HVHZ code compliance for every exterior assembly, and a building department that answers to the Village, not the county. Homeowners call us when they’re adding square footage, replacing a roof that has taken thirty years of salt air, or installing impact-rated windows that meet Miami-Dade’s strictest standards. A typical home addition in Key Biscayne runs $45,000 – $130,000. Impact window installation runs $8,000 – $25,000. Roof replacement runs $8,000 – $20,000.
Permit Navigation and Inspection Scheduling
The Village of Key Biscayne’s building department operates on its own timeline, with inspection slots that fill differently than Miami-Dade’s. We maintain relationships with the local inspectors and know their sign-off priorities. This matters when your rough electrical sits waiting and your family is living in a construction zone.
Material Delivery and Crane Coordination
Every concrete pour, rooftop equipment lift, or truss delivery crossing the Rickenbacker gets a backup window built into the schedule. We’ve seen a single causeway accident idle a crane crew for half a day. We don’t let that idle your project budget.
Remodeling Contractor in Key Biscayne
Remodeling Contractor projects in Key Biscayne almost always involve homes rebuilt or heavily repaired after Hurricane Andrew in 1992 – structures now thirty-plus years old with aluminum wiring, corroded rebar, and first-generation impact windows failing in the salt air. When you open walls in a 1994 rebuild off Harbor Drive, you find what the original contractor covered up. We price for this reality. A kitchen remodel runs $14,000 – $45,000. A bathroom remodel runs $9,000 – $28,000. Cabinet installation runs $4,000 – $13,000. Countertop installation runs $2,000 – $6,500.
Opening Walls and Finding What’s Hidden
On a 1994 rebuild off Harbor Drive, our crew opened the kitchen wall and found aluminum branch wiring spliced to copper, termite-softened framing around a load-bearing header, and a subfloor that had been wet so long the plywood delaminated in sheets. We stopped work, documented everything, priced the wiring replacement, header repair, and new subfloor as a written change order with photo attachments, and only resumed once the owner signed off. The final kitchen landed inside the revised scope – no surprise invoice, no mid-job shutdown.
Written Allowances Before Work Starts
Every Key Biscayne remodel contract includes allowances for the conditions we know we’ll find: outdated wiring, undersized or rotted framing, failed waterproofing. The written price you receive before any work starts includes these contingencies. If we don’t use them, you don’t pay them. If we need them, the price is already agreed.
Trusted Brands We Service in Key Biscayne
Our Key Biscayne projects specify materials that hold up to barrier-island conditions: cabinets from KraftMaid and Wellborn, countertops from Cambria and Silestone, fixtures from Kohler, Moen, and Grohe, and exterior cladding from James Hardie. For accessory dwelling units and modular additions, we also work with Abodu and Dvele – factory-built systems engineered to HVHZ standards that cut on-site construction time and causeway crossings. Every product carries a manufacturer warranty you can verify independently. We stock common hardware and fasteners locally to avoid waiting on a delivery that has to cross the Rickenbacker twice.

AfterCommon General Contractor Problems We See in Key Biscayne Homes
- Concrete spalling and corroded rebar in post-Andrew slabs. The salt air penetrates concrete that was repaired quickly after 1992 but not always to modern standards. We assess this before quoting any flooring or structural modification.
- Failed first-generation impact windows and doors. Those 1990s installations are reaching end of life. Replacement requires NOA-approved assemblies that meet current HVHZ codes, not just off-the-shelf impact glass.
- Termite damage in soft framing around headers and sill plates. Key Biscayne’s humidity and older wood treatments create conditions we find once walls are open. We build repair pricing into the original contract as a named allowance.
- Outdated electrical panels and aluminum branch wiring. Homes rebuilt in the early 1990s often still have panels that won’t handle modern loads. We inspect and price this before demolition, not after your kitchen is gutted.

FAQs About General Contractor in Key Biscayne
Expect NOA-approved impact-rated assemblies for any exterior opening you touch, updated electrical grounding if your panel is older than 2008, and possibly elevated slab or flood-resistant material requirements depending on your FEMA zone. We build these upgrades into your written price as line items before demolition starts, not as surprises after walls are open. Call (949) 850-9896 for an exact quote – estimates are free.
We stop work, photograph everything, and prepare a written change order with priced options before touching anything. On that Harbor Drive kitchen, we found aluminum wiring spliced to copper, termite-softened framing, and delaminated subfloor – all documented, priced, and approved before we resumed. No mid-job shutdowns, no surprise invoices. Call (949) 850-9896 to talk through how we structure allowances for your specific project.
Three factors: causeway logistics add delivery and crane scheduling constraints that mainland jobs don’t face; the Village’s independent permit queue requires separate familiarity and timeline padding; and HVHZ code compliance mandates more expensive, impact-rated materials for every exterior assembly. Contractors who underbid by ignoring these realities either lose money or cut corners. We price for the job as it actually exists on the island. Call (949) 850-9896 for a written estimate that accounts for all three.
The Village of Key Biscayne runs its own building department with its own inspectors, permit counters, and inspection queues. We pull through the Village for every Key Biscayne project and maintain relationships with their staff to keep inspections moving. Treating island permits like Miami-Dade’s is a common mistake that stalls projects for weeks. Call (949) 850-9896 and we’ll confirm the exact permit path for your address.
A realistic allowance for a typical 1990s Key Biscayne kitchen includes $3,000 – $6,000 for electrical panel and wiring updates, $2,000 – $4,000 for framing repairs around headers and sill plates, and $1,500 – $3,000 for subfloor or waterproofing remediation. For bathrooms, we typically allow $2,000 – $4,000 for plumbing stack updates and $1,000 – $2,500 for concrete or tile-bed repairs. These are written into your contract before work starts. If we don’t need them, you don’t pay them. Call (949) 850-9896 for an allowance breakdown specific to your home’s age and condition.
