70 Florida-licensed plumbing subcontractors serve Florida Keys (Monroe County). Browse listings below, or create a free* GC account to see phone and email and invite a sub to bid on your RFQ.
Most of these plumbing subcontractors are based in Key West (23), Key Largo (10), Tavernier (10), Marathon (7), Summerland Key (6), and Cudjoe Key (4) — plus 10 more across the metro.
Plumbing subcontractors handle the domestic water, sanitary waste and vent, storm drainage, natural gas piping, and fixtures on a project — underground rough-in, above-ground rough-in, water heaters and pumps, backflow preventers, and final fixture sets. On commercial jobs they price from the plumbing drawings and spec, coordinate with mechanical and underground utility for connection points, and pull the permits and schedule the inspections on their portion of the work.

When a GC sends a plumbing RFQ, they're usually looking for a quote against a defined scope: the plumbing drawing set and Division 22 spec section, a clear inclusion and exclusion list (underground, fixtures, water heaters, gas, medical or lab gas, grease waste), and the sub's read on long-lead items like specialty fixtures and large water heaters. For bid prep a GC typically wants pricing broken out enough to compare apples-to-apples, confirmation the sub priced to the spec book, and the sub's license and insurance on file.
Plumbing contracting in Florida is a state-licensed trade, regulated by the Construction Industry Licensing Board (CILB) under the DBPR. There are two tiers: a certified plumbing contractor (license prefix CFC) is authorized to work anywhere in the state, while a registered plumbing contractor (RF) is limited to the local jurisdiction that issued their competency card. Florida treats unlicensed contracting as a crime, so a GC confirming a sub's active CILB license is doing basic bid-prep diligence — which is why every plumbing sub in this directory carries its DBPR license number.
Yes. Plumbing contracting is regulated statewide by the Construction Industry Licensing Board (CILB) under the DBPR. A certified (CFC) license works anywhere in Florida; a registered (RF) license is limited to the jurisdiction that issued it.
Certified plumbing contractors can take work anywhere in Florida. Registered plumbing contractors can only work in the local jurisdiction that issued their competency card.
The plumbing drawing set and Division 22 spec section, a scope inclusion and exclusion list (underground, fixtures, water heaters, gas), any long-lead specialty items, the bid deadline, and whether a site visit is required.
Yes. GCs post an RFQ and invite matched subs by trade and service area; invited subs are notified and can submit a bid for your bid prep.
Listings are seeded from public Florida DBPR license data, and a sub can claim its listing and upload a credential for a one-time review. The badge reflects what was reviewed: a verified state license earns License Verified — the usual path for a plumbing sub — a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows the Verified Pro umbrella.
