First question: whose warranty is it?
Two different promises are often blended in sales talk. A product warranty comes from the coating manufacturer and usually concerns the material itself, whether the product was defective or failed when installed to its specifications. An installation or workmanship warranty comes from the installer and concerns the work: prep, application, and adhesion to your slab. A floor can involve both, either, or a single combined document from the installer.
Ask for the actual document, not a summary on a brochure. Note who you would contact for a claim, whether that party is the installer who will do your job, and what happens to the promise if that business changes hands. NorCal Epoxy Floors is a referral service, not the installer, so warranties on work you book through a matched pro are provided by that independent provider, which is exactly why getting their terms in writing matters.
What coverage usually centers on
Term length alone tells you little without those definitions. A shorter warranty that clearly covers delamination with a local installer who will return is a different thing from a longer headline term full of conditions that are hard to meet.
Exclusions worth reading twice
- Moisture. Failures tied to slab moisture are a common exclusion or condition, which is why testing before install matters so much. See concrete moisture testing: if a system was installed over a slab above its limits, a claim can turn on that record. Ask what was tested, what the result was, and keep it.
- Hot-tire pickup and tire staining. Some terms separate true adhesion failure at the tire line from surface marking left by hot tires. Our guide to hot-tire pickup explains the difference; ask which one the warranty treats as a covered failure.
- Cracking and slab movement. Coatings follow the concrete. New cracks, joint movement, and settlement that telegraph through the floor, covered in cracks, spalling and control joints, are commonly excluded because they are slab behavior, not coating behavior.
- Chemical damage, impact, and misuse. Dropped sharp tools, dragging heavy equipment, strong solvents left sitting, and similar events are usually wear-and-abuse exclusions rather than covered failures. Normal cleaning guidance in winter and rain-season care helps avoid grey areas.
- Appearance change over time. Gloss loss, light scratching from grit, and UV ambering where a non-UV-stable layer is exposed, see epoxy yellowing and UV exposure, are often treated as expected aging, not defects. Ask before you assume they are covered.
Conditions that can decide a claim
- Cure and use conditions. Parking before the stated return-to-service time, see how long before you can park, can be used to dispute an early failure. Keep the installer’s written timing and follow it.
- Maintenance conditions. Some terms expect reasonable care: cleaning up strong chemicals promptly, not using harsh methods the installer warned against. Keep any care sheet you are given.
- Transfer and notice. Ask whether the warranty transfers if you sell the house, a point that connects with HOA and resale considerations, and how soon a problem must be reported once you notice it.
- Who did later work. Recoating, patching, or altering the floor with another product can void terms. If the floor later wears, read our guide to recoating a worn garage floor and check the original terms first.
A short checklist to use before you sign
- Can I have the full warranty document, not just the term in years?
- Who honors it, the installer, the manufacturer, or both, and how is a claim started?
- Does it cover peeling and delamination, and is the remedy repair of the area or something broader?
- What are the moisture, movement, chemical, and tire-related exclusions, in plain language?
- What records do I keep, quote, moisture result, product and system name, install date, and care instructions?
Cost context
A clear, written warranty is part of what separates a professional system from a kit or a paint job, but it does not change the general price picture by itself. Most professionally installed 2-car garages in our region land in the $2,400–$6,000 range as clearly-general guidance, see the cost guide. That is not a quote for your garage. Compare warranties alongside systems and prep, not as a standalone number of years.
The bottom line
Judge a warranty by its definitions, exclusions, and remedy, and by whether a local installer will be there to honor it. Get the document before work starts, keep your install records together, and follow the cure and care instructions you are given. Then the warranty is what it should be: a clear backstop for a floor that was tested, prepped, and installed properly in the first place.
