How often should an office be deep cleaned?

Quarterly. For a typical Miami office that already has regular janitorial service, we schedule a deep clean every three months. A low-traffic suite can stretch that to twice a year — the floor, not the ideal — and gyms, clinics, and anywhere food is handled should reset monthly. That’s the rule from our operating playbook; the rest of this article is when to bend it.

What the deep clean adds on top of the nightly visit

A working janitorial schedule already covers a lot. On the published JAS scope, every visit handles restrooms, trash, the break room, high-touch points, and the lobby; a weekly rotation carries floors throughout, desks, and interior glass; and a monthly detail line picks up baseboards, door frames, switch plates, air vents, window sills, light fixtures, shelf tops, and the grout and tile edges in restrooms. Those task names come straight from our janitorial services page, which publishes the three tiers as the starting point for any contract.

So what’s left for a deep clean? Time, mostly. Every one of those detail lines rides inside a normal evening window, in a furnished, occupied office — the crew works around loaded desks, parked chairs, and rooms that must be ready by 8am. A deep clean is the visit scoped so nothing has to be worked around: furniture gets moved and cleaned behind, chair bases and casters get degreased, vents get more than a wipe, partition glass is done floor to ceiling, the kitchenette is handled inside and out, and the floor edges and corners a nightly pass skims get real dwell time. Nothing on that list is exotic. What’s exotic is having enough hours in one visit to do all of it at once.

Miami runs its own clock on this. The AC works year-round, so the film that settles on high surfaces and vent grilles never takes a season off; the rainy months — June through November, roughly — track grit and moisture through every entry; and the sun through the glass most offices here have makes six months of skipped detail visible in a way a shaded suite in another city can hide. Quarterly isn’t a national average we borrowed. It’s what keeps a Miami office looking genuinely clean between resets.

The cadence, space by space

• Quarterly — the default. For a typical office on nightly or weekly janitorial service, four deep visits a year keep the accumulation curve flat: each reset arrives before the last one has worn off, and the regular visits stay fast because they aren’t quietly carrying backlog.
• Twice a year — the floor, not the ideal. A small professional suite — few visitors, no real kitchen, the same handful of people — can hold six months between deep visits. We don’t recommend stretching past that: beyond the half-year mark, the first part of the next visit is spent winning ground back instead of holding it.
• Monthly — gyms, clinics, and food-adjacent areas. This isn’t cleaner’s opinion so much as soil load: sweat, grease, and sheer people-volume load surfaces far faster than a desk office does, and these are spaces their own members, patients, and customers judge every day. In practice, the “monthly deep clean” here is simply the contract’s detail line promoted to a faster frequency.

Cadence is a starting point, not a law. The signals that a quarter is running long are all visible ones: carpet edges darkening against the baseboard, streaks around the AC vents within weeks of the last detail pass, a break room that greets you with a smell on Mondays, or simply more people on the same floor than last year. When the space says a quarter is too long, believe the space, not the calendar. And if your underlying question is the cadence one layer down — how many regular visits a week your office needs — we answered that separately in how often an office should be professionally cleaned.

Put it on the contract, not on memory

The offices that actually get their quarterly deep clean are the ones where it’s a dated line inside the contract — not the ones counting on somebody remembering in March. At JAS, every commercial job starts from a written scope of work you approve before the first visit, and the deep visits belong in that document as scheduled entries alongside the nightly ones: same document, same crew, different depth. Billing lands after each completed visit, with no long-term lock-in, and on eligible completed visits the CleanCheck photo report is the record that the quarter’s reset actually happened. For the fine print of which task rides which frequency between deep visits, there’s the daily, weekly, and monthly office cleaning checklist.

What it costs — and where the number comes from

We won’t invent a sticker price here, because there isn’t one. The published anchor for commercial work is $185 per weekly visit for spaces up to 1,000 sq ft — and that row is a maintenance visit on a floor cleaned days ago, not a deep one. A deep visit on the same footprint is scoped on a walkthrough, with the quote back in writing, usually within one business day. The full answer to the one-off price question — what moves the number, which published anchors to reason from, when your “deep clean” is really post-construction — lives in how much a one-time office deep cleaning costs.
