Answers before you book
Everything restaurant and business owners ask us before booking — straight answers, no sales pitch.
Are you licensed, bonded, and insured?
Yes — Corona Building Cleaning is fully bonded and insured for commercial work, including restaurants, offices, and post-construction sites. Documentation is available on request for property managers and health inspectors.
What areas do you serve?
We serve restaurants and businesses throughout Eastvale and the surrounding Inland Empire area. Check our Service Areas page for the full list of cities we cover.
What types of businesses do you work with?
Restaurants, commercial kitchens, offices, and retail spaces — every job is cleaned to fit health-code and sanitation requirements specific to your industry.
How often should I schedule cleaning service?
It depends on your business type — most commercial kitchens benefit from nightly or several-times-a-week service, while offices often do well with 2–3 visits per week. We'll recommend a schedule during your free walkthrough.
Do you work nights and weekends?
Yes — we schedule around your hours of operation, including evenings, overnight, and weekends, so cleaning never interrupts business.
How fast can you start?
We typically offer a free walkthrough and quote within the same week of your request, and can schedule your first service shortly after.
Do you bring your own equipment and supplies?
Yes, our crews arrive fully equipped with commercial-grade tools and cleaning products for every job — nothing for you to supply.
What's included in a restaurant deep clean?
Kitchen exhaust hoods and filters, degreasing stoves and flat-tops, floor and drain sanitation, dining areas, restrooms, and trash areas — a full checklist tailored to pass health inspections.
