Where we're closest.
Ontario, CA
Ontario is the logistics core of the Inland Empire — distribution centers, cold storage, light manufacturing and the commercial buildings that support them, clustered around the airport and the I-10/I-15 interchange. That building stock is mostly concrete, mostly high-traffic, and mostly running more than one shift.
Ontario servicesRancho Cucamonga, CA
Rancho Cucamonga mixes professional office and medical space with a substantial industrial corridor along Foothill and 4th. Office and medical tenants expect a visibly maintained common area; the industrial side needs floors and docks that hold up to equipment traffic.
Rancho Cucamonga servicesRiverside, CA
Riverside carries the region's deepest stock of institutional and civic buildings alongside its commercial corridors — which means terrazzo, natural stone and older hard-floor systems that reward restoration over replacement.
Riverside servicesUpland, CA
Upland's commercial base skews toward professional offices, medical suites, schools and neighborhood retail centers — buildings where glass, entries and common areas carry most of the visual weight.
Upland servicesFontana, CA
Fontana is heavy industrial and distribution — large-footprint warehouses, steel and manufacturing, and the dock and yard surfaces that come with them. Concrete care and exterior pressure washing carry more weight here than anywhere else in the service area.

How we cover five counties.
How does Nexara cover five counties from one Ontario base?
Nexara is based in Ontario, CA and works directly in the Inland Empire cities of Ontario, Rancho Cucamonga, Riverside, Upland and Fontana. Coverage extends into Los Angeles, Orange and San Diego Counties when a facility's scope — size, frequency, or specialized service mix — justifies a dedicated program.
Proximity is not just a convenience line. A building close to the Ontario base is easy to walk, inspect and revisit; a program in a farther county needs enough recurring work to justify dedicated scheduling and travel, which is why scope matters more than distance alone.
What does it mean for 'scope to justify a dedicated program' in a farther county?
It means the size and frequency of the work — a recurring janitorial contract, a multi-building portfolio, a large specialized project — need to be enough to support scheduling a crew into that market reliably, rather than a single small job requiring a special trip each time.
A one-time floor project in Orange County is evaluated differently than a recurring nightly janitorial contract there. Call before assuming a location is out of range — Nexara will say honestly whether a specific site and scope work well, rather than accepting a mismatched account.
Which counties does Nexara serve, and what facility types are typical in each?
San Bernardino County is home base, with the most direct city coverage. Riverside, Los Angeles, Orange and San Diego Counties are served for facilities whose scope supports a dedicated program, spanning the same commercial, manufacturing, education and regulated facility types Nexara works with in the Inland Empire.

Why is Ontario, CA the base for a five-county service area?
Ontario sits centrally in the Inland Empire, close to San Bernardino County's manufacturing, distribution and commercial corridors, and within reasonable working distance of Riverside County. That positioning is what makes direct, frequent coverage of the five named Inland Empire cities practical without an intermediate branch office.
Nexara's office is at 1849 E 4th St #305, Ontario, CA 91764. No drive-time figures are published here unless computed from a verified source; ask directly about response timing for a specific address.
What should I do if my facility is outside the five core cities?
Call 909-750-2614 and describe the facility's location, size and the service needed. Nexara will tell you honestly whether the site and scope work well for a dedicated program, rather than accepting an account that cannot be served reliably.
This applies most often to Los Angeles, Orange and San Diego County facilities, where coverage depends on the scope of the specific engagement rather than blanket availability. See contact to request a walkthrough once location and scope are discussed.
What facility managers ask us.
Do you serve every city in San Bernardino and Riverside Counties, or only the ones listed?
The five named cities — Ontario, Rancho Cucamonga, Riverside, Upland and Fontana — have the most direct, frequent coverage. Other cities within San Bernardino and Riverside Counties may also be served; call to confirm a specific address.
Is there a minimum contract size to be served in Los Angeles, Orange or San Diego County?
There is no fixed minimum published, because it depends on the facility, the service requested and how it fits into scheduling. A recurring contract is easier to justify at distance than a single small job; ask directly about your specific situation.
How far in advance do I need to schedule if I'm outside the Inland Empire?
Farther counties generally need more advance notice to fit into a dedicated schedule than Inland Empire work. Discuss timing when you call or submit a walkthrough request through the contact page.
Which county page should I check for my building's specific requirements?
Each county page under service areas covers the typical facility types and scheduling notes for that market. City pages for Ontario, Rancho Cucamonga, Riverside, Upland and Fontana go into more local detail.
Does Nexara serve facilities near the ports or logistics corridors in the Inland Empire?
Distribution and logistics facilities are common in San Bernardino and Riverside Counties, and Nexara's pressure washing and parking lot sweeping services are built around dock aprons and truck courts typical of that facility type.
Can a multi-site company get one contract covering locations across several counties?
That is discussed case by case, since each site still needs its own walkthrough and scope regardless of county. A shared point of contact and consistent standard across sites is part of what the owner-led model is designed to support.
