Choosing the Right Epoxy Contractor in St. Louis

Choosing an epoxy contractor in the St. Louis area shouldn’t be a gamble. The right research upfront helps you avoid companies that overpromise and underdeliver. Here’s how to separate the professionals from the contractors who are just chasing the lowest bid.


Start with Reviews and References

  1. Online Reviews
    Google reviews, Facebook recommendations, and other online platforms give you a sense of how a company treats customers. Look for patterns rather than just star ratings. Do multiple reviewers mention the same strengths or problems? Are recent reviews consistent with older ones?

  2. Request References
    Ask contractors for references from projects in your area. A company that’s been around and does good work won’t hesitate to connect you with past clients. If they can’t or won’t provide references, that’s a red flag.


Examine Portfolios and Photos Carefully

  1. Quality and Consistency
    Photos of completed jobs tell you a lot about quality and consistency. Look for:

    • Clean edges

    • Even flake distribution

    • Attention to detail in how the floor meets walls and transitions

  2. Before-and-After Photos
    Before-and-after photos are especially useful. They show whether the contractor handles real-world slabs—old concrete, cracks, stains—or just works on perfect surfaces. If every photo looks like a showroom floor, ask whether they’ve worked on slabs similar to yours.

  3. Prep Work Evidence
    Pay attention to the prep work. Do you see evidence of proper grinding and cleaning, or does it look like coatings were applied over questionable surfaces?


Ask About Process and Prep

During estimates, ask contractors to walk through their process. Key questions to ask include:

  • How do they prepare the surface?

  • What equipment do they use?

  • How do they handle moisture, cracks, and old coatings?

A professional contractor will explain these steps in detail because they know that prep is what makes or breaks the job. Vague answers or a focus only on the coating itself suggests corners might be cut.


Check Licensing, Insurance, and Business Standing

  1. Verify Licensing and Insurance
    Make sure the contractor is properly licensed and insured. This protects you if something goes wrong during installation. Ask for proof of insurance and don’t skip this step.

  2. Longevity of the Business
    How long has the company been in business? Longevity suggests they’re doing something right and will be around if you need warranty service down the road.
