Not All Contractors Are Equal
A Certified General Contractor (CGC) holds the highest level of Florida contractor licensing. Here's what that means for your project.
Typical Contractor
Blue Diamond (CGC)
Dock Construction & Marine Building
Most general contractors can't build docks. We can. Blue Diamond is one of the few CGC-licensed firms in Florida that handles both residential construction and marine dock work — serving waterfront properties in Jacksonville and Fort Lauderdale.

What Homeowners Say
Trusted by Northeast Florida Families

Jacksonville Beach Homeowner
Complete Siding Replacement
“We needed a contractor who could handle both our dock repair and a home addition. Blue Diamond was the only company we found that could do both under one license. Saved us time, money, and headaches.”
Ponte Vedra Beach Homeowner
