Built to Withstand Salt, Storm & Time.
30+ years protecting Florida Keys properties from salt-air deterioration. Trusted by the City of Key West and Monroe County for critical infrastructure — and by homeowners who refuse to wait until it's an emergency.
The Silent Threat
Salt-laden coastal air penetrates porous concrete, attacking the protective oxide layer on embedded reinforcing steel. The corroding rebar expands up to 6–8 times its original volume, cracking and breaking apart the structural concrete from within.
This process — called spalling — is not theoretical in the Florida Keys. With constant salt exposure, high humidity, and hurricane-driven moisture, it is actively happening to structures throughout Key West and Monroe County right now.
Sharp Edge Construction catches these problems before they become emergencies — and fixes them permanently with marine-grade materials engineered for the Keys.
About Sharp Edge
Founded by Gerardo Betancourt, Sharp Edge Construction brings over three decades of hands-on construction expertise to every project. From precision spalling repairs to large multi-floor structural restorations, Gerardo has personally overseen the full spectrum of construction work in the Florida Keys.
What sets Sharp Edge apart is a deep understanding of the unique challenges that the Keys' coastal environment presents. Years of working with salt-air degradation, hurricane damage, and tidal moisture have developed an expertise in materials science that most contractors simply don't possess. Every material, every technique, and every structural decision is made with the Keys' harsh environment in mind.
This expertise has earned the trust of the City of Key West and Monroe County, who rely on Sharp Edge for critical infrastructure projects. That same government-grade quality is applied to every residential and commercial project — because protecting your property from the elements isn't just a service, it's a responsibility.
Our Expertise
Every service is built around one fact: the Keys are the most aggressive environment for concrete in the United States. We specify, mix, and install for that fact.

Spalling is the cracking and breaking of concrete caused by corroded reinforcing steel inside the structure. In the Florida Keys, constant salt-laden air penetrates concrete and corrodes the rebar, which then expands 6–8 times its original volume and breaks the surrounding concrete apart from within. Left untreated, it leads to balcony failures, beam collapses, and major structural emergencies. It's the single most common structural problem in coastal Florida.
Yes. We serve Key West, Stock Island, Big Coppitt Key, Summerland Key, Big Pine Key, Marathon, and all of Monroe County. Our office is at 411 Crane Blvd, Summerland Key, FL 33042 — central to the lower and middle Keys.
Yes. Sharp Edge Construction holds Florida State License #SP4420, is Monroe County certified, and carries full general liability and workers' compensation insurance. We are also ranked in the top 11% of 191,428 Florida-licensed contractors on BuildZoom.
Yes. We have an established relationship with local government building departments, multiple bid nominations, and a track record of successful contract completions including infrastructure projects, bridges, museums, and historical building restorations across the Keys.
We offer emergency response for critical structural failures across Monroe County. Call (305) 797-0630 directly for emergency situations — we will mobilize temporary shoring and bracing as quickly as our team can reach the site.
Standard concrete and rebar are designed for inland environments. In the Keys, they begin corroding within years of installation. Marine-grade concrete uses specific admixtures, lower water-to-cement ratios, and corrosion-resistant or epoxy-coated steel — engineered specifically for chloride-rich coastal exposure. The upfront cost is higher; the lifecycle cost is dramatically lower.
It depends on the extent of corrosion and the size of the structure. A single balcony may take 1–2 weeks; a full multi-unit building restoration can take several months and involves temporary shoring, careful demolition of damaged material, treatment of corroded reinforcement, and a phased marine-grade concrete pour. Every project begins with a free on-site assessment so we can give you a realistic schedule and scope.
