How to Choose a Commercial Flooring Contractor: Questions to Ask Before You Sign

Why the Wrong Choice Is Expensive, Not Just Disappointing

A failed commercial floor coating doesn't just look bad — it means downtime for removal and reinstallation, on top of the original cost. Choosing the right contractor upfront is meaningfully cheaper than fixing the wrong one's work later, and there are specific questions that reliably separate a qualified commercial installer from one that isn't.

Ask About Moisture Testing, Specifically

Does the contractor test for concrete moisture before quoting a final price, and which method do they use? A contractor who doesn't mention this at all, or treats it as optional, is skipping the single most common root cause of early coating failure. This should be a standard part of any commercial estimate, not an upsell.

Ask How They Prepare the Surface

Mechanical preparation — diamond grinding or shot blasting — versus a quick acid etch is one of the biggest quality differentiators in this industry, and it's largely invisible in the finished product until the coating starts failing a year or two later. Ask directly what method they use and why.

Ask for Facility-Specific System Recommendations

A contractor who proposes the same system for a warehouse, a restaurant kitchen, and a medical clinic without asking about your specific traffic and chemical exposure is applying a one-size-fits-all approach to jobs that genuinely aren't one-size-fits-all. The right answer should sound different for each facility type.

Ask About Warranty Terms in Plain Language

What specifically is covered, for how long, and what would void it? A vague "Written warranty terms" without clear terms is worth less than a specific, clearly defined warranty with a shorter stated term.

Ask About Licensing, Insurance, and References

Confirm they're licensed and insured to work in Indiana, and ask for references from commercial projects similar in size and type to yours — not just residential garage jobs, which use different systems and installation standards entirely.
