24-hour re-clean guarantee

Commercial cleaning keeps your workplace presentable without interrupting a single working hour. Lumum Cleaning services offices, retail floors, studios, clinics, and small facilities across Chicago on a schedule you set — nightly, several times a week, or weekly — with most work done after hours or overnight so your team arrives to a finished space. Pricing is per square foot rather than per hour, so the invoice does not move when a job runs long. Every cleaner is background-checked and insured, and we carry a certificate of insurance your building manager can verify. Spaces over 10,000 square feet get a free walkthrough before we quote, because a number sight-unseen would be a guess.

Who it's for

Offices, studios, retail floors, clinics, salons, and small facilities that need a consistent standard and an invoice that does not surprise the finance team.

Pricing

What it costs

Commercial cleaning is priced per square foot with a $275 minimum per visit. Restaurants and medical facilities carry a surcharge for the additional standards involved. Recurring schedules reduce the per-visit rate.

Prices are live estimates from our pricing engine for a typical layout, before your first-clean discount. Your exact price depends on rooms, condition, and add-ons, and is shown up front in the quote — never after the job.

The process

How it works

01
Scope the space
Tell us the square footage, facility type, and how often you need us. Under 10,000 sq ft you get a price immediately.
02
Walkthrough if needed
Larger or specialised facilities get a free on-site walkthrough so the quote reflects the actual building, not an average.
03
Set the schedule
Nightly, three times a week, weekly — whatever fits. Most clients choose after-hours or overnight so nobody is working around us.
04
Consistent delivery
The same team wherever possible, working a fixed checklist. Anything below standard gets re-done within 24 hours.

How long it takes

A 2,500 square foot office typically takes two to three hours; 5,000 square feet, three to five. Overnight work is scheduled to finish before your earliest arrival. Because pricing is by area rather than by hour, a longer night costs you nothing extra.

How to prepare

Give us access details — key, fob, code, or building security contact
Tell us which areas are off-limits or need separate arrangements
Ask your building manager what certificate of insurance they require; we will send it
Name one point of contact for feedback so issues get resolved, not repeated

Frequently asked questions

Do you clean outside business hours?

Yes, and most clients prefer it. Evening, overnight, and weekend schedules are standard, so your team never works around a cleaning crew.

Are you insured, and can my building manager verify it?

Yes. Lumum Cleaning is licensed, bonded, and insured, and we provide a certificate of insurance naming your building or landlord as required.

How is commercial cleaning priced?

By square foot, not by the hour, with a $275 per-visit minimum. That means an unusually slow night never turns into a larger invoice. Restaurants and medical spaces carry a surcharge because the standard is higher.

Do you need a walkthrough before quoting?

Under 10,000 square feet, no — you get an instant price. Above that, we do a free walkthrough first, because quoting a large facility sight-unseen would be guessing.
