We’ve been using Premium Services for our office cleaning, and they’ve been fantastic. The office always looks clean, fresh, and well-maintained when they finish. Their team is reliable, pays attention to the small details, and consistently does a thorough job without disrupting our workday. Communication has been excellent, and if we ever need to adjust the schedule or request something extra, they’re always accommodating and quick to respond. It’s hard to find a cleaning company that’s this dependable, and we’re very happy with the service. I would absolutely recommend Premium Services to any business looking for professional office cleaning.

What our janitorial & custodial services include
Each janitorial & custodial services program is built around your facility. Here is the work most facility and operations managers ask us to cover.
What a janitorial service includes, and how to set one up
"Janitorial" gets used for everything from a weekly office tidy to a full-time custodial program. For facility and operations managers in Bellevue, Seattle and the rest of the Puget Sound area, the useful question is what the program covers, how often, and who makes sure it keeps happening.
Everything a janitorial program covers
A janitorial program is recurring cleaning plus the routine upkeep that keeps a building usable between deep cleans. In a typical commercial building it covers:
- Restrooms cleaned and disinfected, with soap, paper and liners restocked.
- Trash and recycling collected from every room and taken to the building's containers.
- Floor care: vacuuming carpet, mopping hard floors and buffing where the floor needs it.
- Kitchens, breakrooms and common areas cleaned; high-touch points such as handles, rails and elevator buttons disinfected.
- Entry glass, lobbies and reception kept presentable.
- Supply tracking, so consumables are reordered before they run out.
- Regular walkthroughs with the client to check the work and adjust the scope.
Janitorial, custodial and commercial cleaning
Custodial service is the same work under another name, used more often for schools, churches and public buildings. Commercial cleaning is the broader term: it includes janitorial programs, but also one-time jobs like a post-construction clean or a restaurant turnover. If you need the building cleaned on a schedule, week after week, you are looking for janitorial service.
Nightly, weekly or day porter
Most janitorial programs run at night, after tenants or staff leave, so the crew has the building to itself. Busy offices and buildings with heavy restroom traffic usually need nightly service five days a week. Smaller buildings often run two or three nights a week, with restrooms and trash on every visit.
Buildings that get dirty during business hours, such as lobbies, busy restrooms or shared kitchens, can add a day porter: one person on site during the day who keeps those areas in shape while the night crew handles the full clean.
How we run a janitorial account
Each account gets an assigned, background-checked crew, so the same people clean your building and learn its layout, alarm codes and priorities. The scope is written down task by task with a frequency for each one. When something is missed, you tell one point of contact and it is fixed on the next visit, not argued about.
We work in offices, clinics, retail stores, schools, churches, warehouses and multi-tenant buildings across Bellevue, Seattle, Kirkland, Redmond, Everett and South King County. A company with several sites can keep one vendor and one standard for all of them.
What to ask a janitorial company before you hire
- Will the same crew clean our building every time?
- Can you provide a certificate of insurance and a W-9 before the first visit?
- Is there a written scope with frequencies for each task?
- Are supplies and restroom consumables included?
- How do we report a problem, and when is it fixed?
- Can we change the schedule without renegotiating a long contract?

Real facilities. Real managers. Real reviews.
It’s been a great experience working with Premium Services company. The whole process was smooth from the beginning, and everyone was professional and easy to communicate with. They always showed up on time, kept me updated throughout the job, and the manager was quick to answer any questions I had. Scheduling was simple and flexible, which made everything stress-free. The quality of the work met my expectations, and they clearly care about doing a good job. I would definitely recommend them to anyone looking for a reliable company and would happily work with them again in the future.
Very impressed with the quality of work. The space looks spotless and professionally maintained. The team was efficient, detail-oriented, and easy to work with. Definitely a reliable choice for commercial cleaning

What clean looks like Janitorial & Custodial Services
Recurring janitorial (custodial) service is less about a single clean and more about a program that runs reliably for months without you managing it. Offices tend to say janitorial, while schools, public buildings and property managers often write custodial in their scopes and bids; the work is the same. Ours covers a custom schedule built for your facility: assigned background-checked crews, restroom sanitation and restocking, floor care, high-touch disinfection, trash and recycling, supplies management, and regular quality inspections. Facility and operations managers across Bellevue, Seattle, and the wider Puget Sound region hand us the whole cleaning function so they can stop chasing it. The value is consistency — the same crew, the same standard, regular walkthroughs — visit after visit. We handle the ordering and restocking too, so consumables never run out on your watch, and you deal with one accountable vendor instead of a patchwork of tasks.
Businesses across King and Snohomish Counties — from Eastside offices to Kent Valley facilities — increasingly want one janitorial vendor accountable for the whole building rather than a rotation of one-off cleaners. In a tight local labor market, an assigned, vetted crew that actually shows up and holds a standard is the hard part. We run inspections and keep the same team on your account so the program stays reliable across the region we cover.
We run recurring janitorial and custodial programs across the Puget Sound area with an assigned, background-checked crew for each building, a written scope and one point of contact. We are insured and bonded, supplies are included, there is no long-term contract, and our clients rate us 5.0 on Google.
Quality that slips between visits
Without oversight, cleaning quality drifts and problems only surface when someone complains. Our program includes regular inspections and a consistent assigned crew, so standards are checked and held rather than quietly eroding until a client or staff member notices.
Running out of restroom and cleaning supplies
A restroom with no paper or soap reflects on the whole business, and tracking consumables is a chore nobody wants. We manage and restock supplies as part of the program, so ordering and running out stops being something on your desk.
Juggling multiple vendors and one-off cleaners
Managing separate people for floors, restrooms, and general cleaning wastes your time and produces uneven results. A full janitorial program puts one accountable vendor over the whole building, so you have a single point of contact instead of a patchwork.
Crews that rotate and never learn your building
When the cleaner changes constantly, nobody learns your priorities or your floor plan, and quality shows it. We assign a consistent background-checked crew to your account so the team knows your space and holds your standard every visit.

Is custodial service the same as janitorial service?
Yes. Both mean recurring cleaning and upkeep of a building. Custodial is the term schools, churches and public buildings use more often; the work and the program are the same.

Busy offices and buildings with heavy restroom use usually need nightly service five days a week. Smaller buildings often run two or three nights a week. A day porter can be added for lobbies and restrooms during business hours.
