METHOD AND LIMITS
How these lists were collected
- One answer per assistant, both collected on : ChatGPT with web search on and a US location, and Google Gemini with Google Search grounding and a US location, collected through cloro, a third-party AI answer collection service.
- The question, with San Diego, CA as the city and state: “Who are the best epoxy floor coating contractors in [city], [state]? Give me a shortlist.”
- Answers change from day to day. Ask the same question tomorrow and either list can be different.
- Named by both: names are compared without punctuation, text in brackets, legal endings such as Inc. and LLC, and the city and state; they match when they are then the same, when one is the start of the other, or when both start with the same distinctive word.
- A listing here is not an endorsement by Sourci. Sourci has not vetted these companies, and the order is the assistant’s, not ours.

BEFORE YOU HIRE
How to check a epoxy flooring contractor before you hire
An assistant’s shortlist is a place to start, not a vetting. Before you hire one of these epoxy floor coating contractors:
- Check the licence. Ask which licence or registration the company holds for this work. Licensing rules differ by city and by job size, so confirm what applies with the local building department before work starts.CALIFORNIA LICENSING · STATE LICENCE OR REGISTRATION APPLIES
California licenses flooring contractors under the CSLB C-15 Flooring and Floor Covering classification; ask which classification covers your coating job and confirm it on CSLB's License Check.
Licensing body: Contractors State License Board (CSLB). Look up a licence.
“A flooring and floor covering contractor prepares any surface for the installation of flooring and floor coverings, and installs carpet, resilient sheet goods, resilient tile, wood floors and flooring (including the finishing and repairing thereof), and any other materials established as flooring and floor covering material, except ceramic tile.”

- Ask for a certificate of insurance that names your property, and confirm it with the insurer.
- Ask for two or three references from similar commercial jobs and call them.
- Ask how they test the slab for moisture, how they prepare the surface, and which coating system and thickness they propose for your traffic.
- Get the scope, products, schedule and warranty in writing, and compare at least two proposals on the same scope.
