Office & Commercial Cleaning in Brooklyn

Office and commercial cleaning in Brooklyn looks different than it does in a suburban office park. A lot of the borough's workplaces sit inside older buildings — converted brownstones in Park Slope and Brooklyn Heights, walk-up storefronts in Bushwick and Bedford-Stuyvesant, ground-floor suites in Crown Heights, and newer studio and co-working space along the Williamsburg and Bay Ridge waterfronts. Much of that stock dates to the early 1950s and earlier, which means narrow stairwells, freight-elevator windows, and entryways that catch street grit off the sidewalk all day. We plan our route around the actual building, not a generic floor plan.

Access is the part most cleaning companies underestimate here. With roughly 70% of Brooklyn renting (U.S. Census), most of the offices we clean are leased space inside managed buildings, and the property manager wants a certificate of insurance on file before a crew works after-hours. We are bonded and insured and can have a COI sent to your building before the first visit, so security lets us in and nobody scrambles at the door. For ground-floor and walk-up suites, we carry our own supplies up the stairs and don't count on a loading dock that isn't there.

We schedule commercial cleaning on a custom rhythm — nightly, a few evenings a week, or weekend resets — so the work happens when your team isn't at their desks. A typical Brooklyn visit runs desks, monitors, and phones first, then shared equipment, restrooms, and the breakroom, and finishes with floors so nothing tracked through gets left behind. Restrooms and kitchens get the most attention because they're what staff and visitors notice; we sanitize the fixtures and restock soap, paper towels, and hygiene supplies so you're not the one ordering them.

There's no locked-in annual contract and no pre-authorization hold on your card. You get a real-time quote based on your square footage, the number of restrooms, and how often you want us in — then you decide. Every cleaner on our Brooklyn team is bonded, background-checked, and speaks English, Spanish, and Portuguese, so the walkthrough, the schedule, and any standing instructions happen in whichever language is easiest for whoever runs your office.

Office & Commercial Cleaning in Brooklyn — common questions

How much does office cleaning cost in Brooklyn?

+
It depends on your square footage, how many restrooms you have, and how often you want us in — nightly, a few evenings a week, or weekend resets cost differently. So we give you a real-time quote up front instead of a vague 'starting at' figure, with no pre-authorization hold on your card. Call or message us with your space and hours at (657) 737-7171 and we'll be straight with you.

Can you provide a certificate of insurance (COI) for our Brooklyn building?

+
Yes. We are bonded and insured, and we can send a certificate of insurance to your property manager before the first visit — which is what most managed Brooklyn buildings require before a crew works after-hours. Tell us your building's COI requirements when you reach out and we'll have it on file so security can let us in without any hold-ups.

Do you clean offices after business hours in Brooklyn?

+
Yes — most of our Brooklyn commercial work happens after hours so we're not in your team's way. We set a custom schedule that fits your space, whether that's nightly, a few evenings a week, or weekend resets. For walk-up and ground-floor suites we bring our own supplies up the stairs and work around your lock-up routine.

What does a commercial cleaning visit include?

+
A standard visit covers desks, monitors, keyboards, and phones; disinfecting shared equipment and high-touch surfaces; vacuuming carpets and cleaning floors; emptying trash and recycling; sanitizing restrooms; refilling soap and paper towels; and cleaning the breakroom or office kitchen. We adjust the checklist to your space during the walkthrough.

Do you offer commercial cleaning in Spanish or Portuguese in Brooklyn?

+
Yes — our entire Brooklyn team is trilingual in English, Spanish, and Portuguese. The estimate, the in-person walkthrough, the schedule, and any standing instructions all happen in whichever language is easiest for whoever manages your office. Call us at (657) 737-7171.

Can you provide proof of insurance for our Brooklyn building's property manager?

+
Yes — we're bonded and insured, and Brooklyn commercial and managed buildings frequently ask vendors for proof. We'll share our insurance documentation on request so your property manager has it on file before we begin.
