Check the license covers your job
This is a registered pool/spa contractor license. If your job is a different trade, the contractor needs that license too, or a licensed sub for that part.
Is this your license, or is something wrong?
This status comes from Florida DBPR licensee files (construction and electrical boards), refreshed weekly, file dated November 8, 2026, and it may have changed since. The official record is the one that counts. If it's wrong, the state has to fix it. If our page is the problem, or you want this record off our site, email us or see our corrections page.
