“Deep cleaning” is the most-quoted and least-defined line item in commercial cleaning. Every vendor offers it, and few can say exactly what it covers. Here is what professional deep cleaning services include for an office, clinic, or rental unit, room by room, how they differ from routine janitorial work, and when a commercial space is due for one.
Deep Cleaning vs. Routine Janitorial Cleaning: What Changes
Routine janitorial service maintains a building: trash, floors, restrooms, high-touch surfaces, breakroom counters. It runs on a schedule and assumes the space starts reasonably clean.
A deep clean resets the building. It goes after the buildup a maintenance visit is not scoped to touch: vent covers, baseboards, grout, appliance interiors, light fixtures, the backs of cabinets, and the grime behind and under everything. It takes two to three times the labor of a maintenance visit, which is why it is quoted and billed separately.
The rule of thumb: routine cleaning holds a standard; deep cleaning raises it.
The Room-by-Room Commercial Deep Cleaning Checklist
Use this list to compare bids: if a vendor’s “deep clean” skips half of it, you are paying deep-clean rates for a maintenance visit.
Offices & Workstations
- Desks, monitors, keyboards, and phones wiped and disinfected
- Chair arms, bases, and casters wiped; rolling chairs moved to clean beneath
- Baseboards, door frames, and light switches washed, not just dusted
- Window sills, ledges, and blinds detailed
- Vents and returns vacuumed and wiped
Restrooms
- Tile and grout scrubbed; partitions washed both sides and tops
- Toilets and urinals cleaned to the base, behind, and along the floor seam
- Faucets, flush valves, and dispensers descaled. Cache Valley hard water leaves mineral buildup on fixtures fast
- Exhaust fan covers and vents washed; mirrors polished streak-free
- Floors hand-detailed at edges and behind fixtures; drains cleaned
Breakrooms & Kitchenettes
- Inside the microwave, refrigerator, and oven, including gaskets and door edges
- Cabinet fronts hand-wiped; tops of upper cabinets degreased
- Sink and faucet descaled; backsplash scrubbed
- Coffee station and small appliances moved and cleaned beneath
- Trash and recycling bins washed and sanitized
Lobbies, Hallways & Conference Rooms
- Entry glass and door hardware cleaned inside and out
- Reception counters, waiting-area seating, and conference tables detailed
- High dusting of ledges, signage, and light fixtures
- Hard floors edge-cleaned and machine-scrubbed
Rental Units & Apartment Turnovers
A turnover is a deep clean with a deadline. For heavy buildup, we pre-treat overnight so grease and mineral scale lift instead of being scrubbed at.
- Kitchen appliances inside and out: oven, range hood, refrigerator, dishwasher, microwave
- Cabinets and drawers wiped inside, on the fronts, and along the backs nobody checks
- Bathrooms fully descaled: tub, shower, toilet, vanity, and fixtures
- Closets, shelving, and rods wiped down
- Blinds cleaned slat by slat, unless they are too fragile to handle
- Vents, light fixtures, and ceiling fan blades dusted and wiped
- Baseboards, door frames, and walls washed; scuffs treated
- Floors vacuumed and mopped last
Our move-out cleaning for property managers follows this sequence, and our move-out cleaning checklist goes item by item.
Whole-Building Items
- Vents and cold-air returns vacuumed and wiped throughout
- High dusting: ceiling corners, cobwebs, exposed ductwork, tops of tall cabinets
- Interior door hardware, push plates, and handrails disinfected
- Stairwells swept, mopped, and railings washed
- Floor edges and corners detailed where machines cannot reach
When a Commercial Space Needs a Deep Clean
- Starting a new janitorial or office cleaning contract. Every recurring Queen B account begins with an initial deep clean, billed separately, so maintenance visits start from a real baseline.
- Tenant turnover. A unit deep cleaned between tenants leases faster and photographs better.
- Post-winter reset. After a Cache Valley furnace and inversion season, buildings carry months of dust in vents, blinds, and on every ledge.
- Before a lease inspection or handover. A documented deep clean makes the handover smoother.
- After an event. Conferences, seasonal parties, and trade shows leave more behind than a nightly crew is scoped for.
- Allergy or dust complaints. The source is almost always vents, blinds, and high surfaces a routine visit does not touch.
- Post-construction. Drywall dust settles everywhere; see our post-construction cleaning page.
What Commercial Deep Cleaning Services Cost
Every commercial deep clean is quoted after a free walkthrough, because square footage alone does not reveal how much buildup is waiting. Numbers to plan around:
- $135 is our absolute minimum for any visit.
- $50 per hour per cleaner for hourly work, which is typical for apartment units and move-outs.
- Two to three times the labor of a maintenance visit for the same space.
Recurring clients pay for the deep clean once, at the start of the contract; after that, maintenance keeps the building at that level and the visits short. Our deep cleaning services page covers scope in more detail; a walkthrough gets you a firm number.
Preparing Your Space for the Crew
Every paid hour should go to cleaning, not sorting:
- Clear desks and surfaces. Ask staff to put away papers, personal items, and dishes. We clean around what is left, not under it.
- Send access instructions. Our crews work after hours with a key, badge, or entry code. Tell us about alarm codes, locked areas, and where to leave the key.
- Flag priority areas. If restrooms matter most or a conference room hosts a client Monday, say so and we will sequence around it.
- Point out supplies. Where the janitor closet, water source, and dumpster are.
We walk the space with you before and after the job, so nothing is assumed on either side.
Frequently Asked Questions
How long does a commercial deep clean take?
A small office of 2,000 to 5,000 square feet usually takes a crew of two or three one full evening. A one- or two-bedroom apartment turnover runs four to eight labor hours, longer if the unit needs overnight pre-treatment.
How often should a commercial space be deep cleaned?
Once or twice a year for most offices and clinics, usually spring and fall, with routine janitorial service in between. Rental units get one at every turnover.
Does the deep clean happen after hours?
Yes. Most of our work happens evenings and weekends with a key, badge, or entry code, so your staff never work around us. Every team member is background-checked and legally employed, and Queen B is cleared and trusted by the Cache County Sheriff’s Office.
Is carpet extraction included?
No. Carpet extraction is separate equipment and a separate trade, and we subcontract it for clients who need it. Deep cleans do include thorough vacuuming, edges and under furniture included.
Do you clean private homes?
No. Queen B Cleaning & Disinfecting serves commercial and property-management clients only: offices, clinics, retail, and apartment or rental-unit turnovers.
