What areas does Star's Janitorial Services cover?
Star's Janitorial Services covers Concord, California and the surrounding East Bay. We regularly serve commercial clients throughout Contra Costa County and nearby communities including Walnut Creek, Pleasant Hill, Oakland, Dublin, and San Ramon. Our home base is Concord, and every account is dispatched locally.
How does Star's Janitorial pricing work?
Pricing is quoted per facility, not off a fixed price list. We walk your building, map a detailed scope for each visit (including monthly and quarterly items), and give you a written proposal with a fair, transparent price. Recurring janitorial accounts are billed on a set schedule; one-time and project cleans are quoted as a flat rate.
Is Star's Janitorial Services licensed, bonded, and insured?
Yes. Star's Janitorial Services is licensed, bonded, and insured - License #929771. We are a family owned commercial cleaning company based in Concord, California, and we are happy to provide current license, bond, and insurance details as part of any proposal so property managers and facility owners can vet us with confidence.
Do you subcontract your cleaning work?
Ninety-five percent of our business is managed by our own employees. Five percent is maintained by our contractors, who have a long-standing relationship with Star's. This keeps quality consistent and accountable on every East Bay account.
Are there any hidden fees?
No, there are no hidden fees. We walk your facility, scope the work in writing, and quote a fair, transparent price up front. What you approve is what you pay.
Do you accept credit cards?
Yes, at an additional cost. We also accept standard business payment methods for recurring janitorial accounts across Concord and Contra Costa County.
Do you provide cleaning supplies and equipment?
Yes, we do. Star's brings its own commercial-grade cleaning supplies and equipment to every job, so you do not have to stock or maintain anything.
Is Star's Janitorial Services a franchise?
No. Star's Janitorial Services is a family owned and operated company, not a franchise. When you call, you reach the Concord-based owners who put their name on the quality of every job.
How do you ensure the quality of your cleaning services?
We schedule quality walkthroughs and make sure our service meets your expectations. Crews are continuously trained and audited, and every visit includes before-and-after photo documentation so you can see the work.
Can you provide a bid without seeing the building?
It is best to conduct a walkthrough so we can give you an accurate, custom quote. We will visit your Concord or East Bay facility, map the scope, and return a detailed written proposal.
Are you available 24/7?
Yes. You can call us 24/7 at (925) 521-4048 with any questions, and we build flexible schedules around your operating hours to minimize disruption to your workday.
Do you offer recurring cleaning or just one-time service?
We offer both. Most of our Concord and East Bay clients are on recurring janitorial contracts (nightly, weekly, or a custom route), but we also handle one-time deep cleans, move-in and move-out turnovers, and post-event cleanups. You choose the cadence that fits your facility.
What types of facilities does Star's Janitorial clean?
Star's cleans commercial and institutional facilities across the East Bay: office buildings, medical offices, warehouses, manufacturing plants, industrial buildings, apartment complexes, HOA common areas, and educational facilities. If it is a commercial space in Contra Costa County, we can scope it.
Do you use green or eco-friendly cleaning products?
Yes, on request. We can build your scope around green, low-VOC, and eco-friendly products where facility requirements allow, which is common for medical offices, schools, and shared workspaces. Tell us your preferences during the walkthrough and we will match the product line to your building.
How do I get a quote from Star's Janitorial Services?
Call (925) 521-4048 or email info@starsjanitorialservices.com, or send a request through our contact form. We schedule a walkthrough of your Concord or East Bay facility, then return a detailed written proposal, typically within a few business days.
How fast does Star's Janitorial respond?
Fast response is one of the things our clients mention most. Requests are answered promptly, proposals turn around quickly, and our supervisor coordinates crews locally out of Concord so schedule changes and add-on requests get handled without delay.
Can you handle disinfection and high-touch sanitizing?
Yes. We include disinfection of high-touch surfaces and can add enhanced sanitizing to any recurring or one-time scope. This is standard for the medical offices, childcare centers, and shared facilities we serve across Contra Costa County.
Why choose a local Concord janitorial company over a national chain?
Because a local, family-owned team is accountable to you, not a call center. Star's Janitorial Services is based in Concord, California and has served the East Bay since 2012. You get direct communication, before-and-after photo documentation, and owners who put their name on the quality of every job. Note: several unrelated companies share the 'Star Janitorial' name in other states; we are the Concord, California business serving Contra Costa County.
How much does commercial cleaning cost in Concord, CA?
Star's Janitorial Services does not publish flat rates because every facility is different. Pricing depends on your building size, cleaning frequency, scope of work, and the type of facility - a medical office or manufacturing plant is scoped differently than a standard office suite. The best way to get an accurate number is a free walkthrough: we visit your Concord or East Bay facility, map the scope in detail, and return a written proposal. Call (925) 521-4048 or use our contact form to schedule.
How much does janitorial service cost per month for a business in Contra Costa County?
There is no universal monthly rate for janitorial service in Contra Costa County because pricing varies with square footage, cleaning frequency, and the full scope of work. Rather than publish figures that may not reflect your situation, Star's Janitorial walks every prospective account, scopes the work in writing, and delivers a transparent proposal - no hidden fees, no guesswork.
