Professional Cleaning. Reliable Service.

GNA Complete Cleaning Services covers Brentwood, Antioch, Oakley, and Pittsburg, in East Contra Costa County, California. We keep the service area tight on purpose — staying close to home is how we keep our scheduling reliable. If you are just outside those cities, call and ask. If we can serve you well we will say so, and if we cannot, we will tell you that instead.

We focus on commercial and recurring work: medical, dental and healthcare offices; commercial properties, professional suites, lobbies and common areas; retail and small business spaces; and Airbnb and short-term rental turnovers. These are the properties where consistency matters more than anything else, which is the kind of cleaning we are built for.

There is no flat rate, because no two properties need the same thing. Cost depends on the size of the space, how much traffic it takes, what is included on each visit, and how often we come. Tell us about your property and the quote is free, with no obligation — call 925-813-9382 or send the quote form.

Call 925-813-9382 or fill out the quote form on this site. Tell us what type of property needs cleaning and roughly how big it is. We talk through what should be covered on each visit and the schedule that fits how you operate. Quotes are free, and there is no pressure and no long sales process.

It depends on your property, not on a package we are trying to sell. A medical office and a small suite of professional offices do not need the same rhythm. When we quote, we look at how many people move through the space before we suggest how often we should be there — which sometimes means recommending fewer visits than you expected, and sometimes more.

Scope is set with you before the first visit, so it matches your property rather than a generic checklist. Most recurring work covers restrooms cleaned and restocked, floors vacuumed, mopped and detailed along the edges, high-touch points wiped down, interior glass and entry doors, trash emptied and liners replaced, and a final walk-through of every room we touched.

Tell us and we come back and make it right. No arguing about it. That is the whole point of hiring a cleaning company — you should be able to stop thinking about cleaning, and if something slips, fixing it is our job and not your problem.

Yes. GNA is a small operation — the owner and a small cleaning crew — and the people who quote your property are the people who clean it. That is deliberate: nobody has to be re-trained on your building, and the standard climbs over time as we learn your problem areas and your busy days.

Yes. We work in English and Spanish, and we are happy to communicate in whichever you prefer. This entire site is available in both languages.

Our work is commercial and recurring rather than residential house cleaning. Short-term rentals and Airbnb turnovers are the residential-style work we do take on, because they run on a commercial rhythm. If what you need is regular house cleaning, we are probably not the best fit, and we would rather tell you that than take the job.
