Deep facility cleaning that happens while your building sleeps
What overnight cleaning covers
Some cleaning work cannot be done during business hours. Stripping and waxing a lobby floor, deep-cleaning a medical exam room, power-scrubbing a cafeteria kitchen, or a full restroom overhaul. These jobs need time, heavy equipment, strong chemicals, and an empty building. That's what overnight cleaning is for.
LPJ Services provides overnight commercial cleaning services for properties across the Chicago area. Our overnight crews work roughly 10pm to 6am, doing deep cleaning, floor care, and the heavy maintenance that needs an empty building and uninterrupted time.

Overnight cleaning is not the same as janitorial service. Janitorial is daily maintenance. Emptying trash, wiping surfaces, restocking restrooms. Overnight is the intensive, periodic work that keeps a building in condition over the long run.
That covers full-facility deep cleaning on a rotating schedule. Floor stripping, waxing and buffing across all hard surfaces. Carpet deep extraction and stain treatment. Kitchen and cafeteria deep cleaning, including hoods, grease traps, equipment and surfaces. Restroom deep cleaning: grout scrubbing, fixture descaling, partition sanitization. Stairwell and elevator cab deep cleaning. High-touch sanitization on door handles, handrails, elevator buttons and light switches. Loading dock and service corridor scrub-down.
Why overnight instead of weekend or after-hours?
For most commercial properties, overnight is the best window because the building is completely vacant (no risk of disruption or chemical exposure to occupants), heavy equipment runs freely without furniture constraints, floors dry fully before morning foot traffic, and there is no competition for elevator or service corridor access.
Weekend cleaning works for some tasks, but many properties are occupied on weekends. Retail hours, Saturday medical practices, Sunday building tours. Overnight provides a reliably empty-building window every weeknight.
Medical and healthcare facilities
Overnight cleaning is particularly critical for medical facilities where infection control standards require thorough disinfection protocols. Our overnight medical cleaning teams work to your facility's documented infection control protocols, use the EPA-registered disinfectants your facility specifies, and maintain separate color-coded equipment for patient areas, restrooms, and common spaces. Every visit is on the record in your client portal, with its photos.
Hospitality and event spaces
Hotels, event venues, and restaurant groups rely on overnight cleaning to reset spaces between evening close and morning open. Our hospitality crews are trained for fast turnover. A post-event ballroom or a late-night restaurant, guest-ready by 6am. For hotels, we handle lobby, restaurant, and public area deep cleaning, and we back up your housekeeping team on guest rooms when you need coverage. Peak occupancy, callouts, or a deep-clean cycle your staff can't absorb.
Security and access protocols
Overnight work in commercial buildings requires strict security protocols. We work with your building security to establish alarm codes, key protocols, access badge procedures, and sign-in/sign-out logs. Our crews carry LPJ identification at all times and follow documented lockup procedures when they exit the building.
Every overnight visit is on the record in your client portal, with its photos.
Combining overnight with daytime services
Most properties that use overnight cleaning also have a daytime program. Janitorial, day porter, or both. The overnight crew handles the heavy lifting; the daytime crew maintains it. That covers the building around the clock on one contract, one account manager, one portal.

What matters on an overnight program.
The window
Typically 10pm to 6am, and the shift moves to fit when your last tenant leaves or your first arrives.
Security
Alarm and key protocols coordinated with your building security, sign-in and sign-out, LPJ identification, and every visit on the record in the client portal.
The heavy work
Overnight is when floors are stripped and refinished, carpets extracted and kitchens deep-cleaned, with nobody in the way.
Medical and specialty spaces
Medical overnight teams follow your infection control protocol, use the disinfectants your facility specifies and keep separate color-coded equipment.
Facility assessment and deep clean mapping
We audit the facility and identify what needs overnight attention (floors, kitchens, restrooms, medical areas) then map a rotating deep clean schedule.
Security and access coordination
We work with your building security to establish alarm codes, key protocols, badge access, and sign-in/sign-out procedures for overnight crews.
Crew assignment and specialized training
Overnight crews are picked for the work required (medical disinfection, floor care, kitchen deep cleaning) and trained on your building's protocols.
Overnight execution
Crews arrive, execute the assigned scope, document completion with photos, and lock up following your building's security procedures.
Morning verification
Your supervisor or building engineer receives a shift report before tenants arrive. Any issues flagged overnight are resolved before business hours begin.
Overnight, answered.
Areas we cover most for overnight cleaning: The Loop, Streeterville, West Loop, River North, South Loop.
What time do overnight crews work?
Typically 10pm to 6am, but we adjust based on your building's schedule. If your last tenant leaves at midnight or your first arrival is at 5am, we adjust the shift to fit.
How is overnight cleaning different from janitorial?
Janitorial is daily maintenance. Trash, surface wiping, restocking. Overnight cleaning is periodic deep work. Floor restoration, kitchen deep cleaning, restroom overhauls, disinfection cycles. Most properties need both, and we bundle them into a single agreement.
How do you ensure security during overnight work?
Documented alarm and key protocols coordinated with your building security, sign-in/sign-out logs, LPJ identification badges, and every visit on the record in the client portal.
Can you handle medical facility overnight cleaning?
Yes. Our medical overnight teams follow your facility's documented infection control protocols, use the EPA-registered disinfectants your facility specifies, and maintain separate color-coded equipment. Every visit is on the record in your client portal, with its photos.
