Office cleaning that's done before your team walks in
Your office should look the same at 8 a.m. every day: emptied bins, clean restrooms, a wiped-down breakroom, vacuumed carpet and dust-free ledges. Advantage Building Services provides recurring office cleaning across Puget Sound, scheduled in the evening or other off-hours around your building access.
We clean single office suites, multi-floor offices and shared office buildings in Seattle, Bellevue, Kirkland, Redmond, Everett, Lynnwood and across the region. The scope is written at a free walkthrough around your space — how many people use it, how many restrooms it has, what your floors are and how often you want service: daily, a few times a week or weekly.
Service is month-to-month with no long-term contract, and if you don't know your square footage, that's fine — send the address and what you know, and we'll work through the details at the walkthrough.

What recurring office cleaning covers
Your scope is tailored at the walkthrough. Most offices start here.
Workspaces and desks
Microfiber dusting of desks, ledges and fixtures, and wipe-downs of shared surfaces, phones and switches.
Trash and recycling
Bins emptied and liners replaced throughout the office on every visit.
Restrooms
Fixtures, mirrors and floors cleaned and sanitized, with consumables restocked as part of your scope.
Breakrooms and kitchens
Counters, sinks, tables and appliance exteriors cleaned so the breakroom is ready every morning.
Carpet and hard floors
Cordless backpack vacuums for carpet, mopping for hard floors, and periodic deep floor and carpet care.
Conference rooms, lobbies and glass
Meeting rooms reset, reception areas tidied and entry glass cleaned for clients and visitors.

Modern by design
Why we're often 15–30% lower
We use modern equipment and practical workflows that reduce wasted setup time and help crews stay productive. That efficiency lets us price many comparable recurring scopes below major janitorial competitors without cutting corners on what your building needs.
Cordless mobility
Cordless backpack vacuums and other mobile tools reduce cord changes, plugging and unplugging, and unnecessary setup.
Modern dusting systems
Microfiber and modern dusting tools help crews move through routine detail work efficiently and consistently.
Right tool for the task
We match equipment and floor-care methods to the surface and the job instead of relying on one old-fashioned process for everything.
Lean local operation
Streamlined scheduling and direct local management mean less overhead, faster decisions, and more of your budget going toward the actual service.

Helpful answers
Simple answers before you reach out
How often should an office be cleaned?
It depends on how many people use the space. Busy offices often choose service several times a week or nightly; smaller or lightly used offices may only need a weekly clean. We schedule anywhere from once a week to seven nights a week and recommend a frequency at the walkthrough.
Do you clean after business hours?
Yes. Evening and other off-hours schedules can be coordinated around building access and operating hours.
How much does it cost to have an office cleaned?
Office cleaning is priced on square footage, frequency, restrooms, traffic, floor types and the exact scope, so final pricing follows a free walkthrough. On many comparable recurring scopes, we're 15–30% lower than major janitorial competitors.
Do I need to sign a long-term contract?
No. Advantage offers month-to-month recurring service with no long-term contract. You can cancel anytime under the agreed service terms.
What if I don't know my square footage?
That's fine. Send the building address and what you know. We can work through the details during the walkthrough.
How hard is it to switch from our current cleaning company?
Not hard. We do the walkthrough, write the scope and set a start date around your building. For qualifying recurring accounts, a free initial cleaning may be available to bring the facility up to standard before routine service begins.
