Commercial janitorial services, nightly or weekly.

Janitorial services from Arbor.

Good janitorial work is quiet. Bins are empty, restrooms are stocked, floors are clean and nobody had to ask. That steadiness is what we build for, whether your building is a two-suite office in Santa Rosa or a school campus in Elk Grove.

Every Arbor plan starts on paper. We list the rooms, the tasks in each one and how often they happen, then a background-checked crew works through that list on every visit. Supervisors come back to look at the results, so the standard in the third month matches the first week.

High-touch points such as door pulls, light switches, counters, faucets and shared equipment are wiped and disinfected as part of the routine rather than as an afterthought.

Choosing how often the crew comes.

Frequency comes down to headcount, hours and how much food and foot traffic the building sees. A school or a busy office with a shared kitchen usually needs a visit every weeknight. A small professional suite often stays fresh on two or three evenings, with the restroom and kitchen covered each time.

Rooms do not all need the same rhythm. Restrooms and breakrooms can be cleaned every visit while private offices and storage rooms are dusted and vacuumed on fewer nights. When daytime traffic outpaces the night crew, a day porter fills the gap.

How janitorial service is priced across our service area

Nightly janitorial is priced by the square foot and billed monthly. Based on 2026 market rates for our area, a building cleaned five nights a week usually runs between $0.15 and $0.24 a square foot each month, with the Lathrop and Stockton side at the low end and Petaluma and the rest of Sonoma County at the top. A small suite with a short task list starts near $0.10, and a busy building with many restrooms and a long list reaches $0.44.

The math is square feet times rate, at the frequency you choose. Picture an 18,000-square-foot professional building in Santa Rosa with two floors of offices, a break room on each floor and eight restrooms. At $0.17, five nights a week, the program runs $3,060 a month. Cut the schedule to three nights and the monthly figure drops, since the crew spends fewer hours inside. Add a day porter and it climbs.

Footage and frequency set most of the price. After those come the count of restrooms and break rooms, the split between carpet and hard floor, and how soon the crew can get in after your staff leave. Labor is most of what a cleaning program costs, and the regional bands sit close together, with Sonoma County slightly higher at the top of the range; the cost guide sets out each band. Refinishing floors and extracting carpet show up as separate line items.
