How to choose a garage floor coating contractor in San Diego.
The difference between a floor that lasts 20 years and one that peels in two usually comes down to prep and the fine print — not the color. Here’s what to ask a San Diego contractor before you sign.
Prep is everything
Ask exactly how they prep the slab. Diamond grinding opens the concrete so the coating bonds mechanically; an acid etch (or no prep) is the #1 reason coatings lift and peel. If a San Diego bid is far cheaper than the rest, skipped prep is usually why — and you’ll pay again to grind off the failure and redo it.
Warranty red flags
- Does the warranty cover both materials and labor? Many “lifetime” warranties quietly exclude one or both.
- Are there moisture exclusions (MVER thresholds, Tramex readings) buried in the terms? Those are often escape clauses to deny a claim.
- Do they apply a moisture-mitigating primer on every job, or only after they “find” moisture on install day and upcharge?
- Can they produce technical data sheets for the products they’re using?
- Are they licensed, insured, and local, with San Diego-area references you can check?
What matters locally
San Diego’s mild coast is easy on people but still works on concrete. Steady UV and marine-layer moisture slowly degrade bare and painted slabs, and many County garages and patios carry years of embedded oil. The climate is forgiving enough that prep, not weather, is usually what decides whether a coating lasts here. From coastal homes to inland County neighborhoods, the slabs we coat are often older and well-used, so grinding out oil and opening the concrete is what makes the finish bond for the long run.
That’s why moisture control and the right prep aren’t optional add-ons in San Diego County — they’re the job. We bring the same standard to every San Diego install, from to the surrounding metro, and we put the number and the scope in writing before we start.
