What the state adds to the price, and what it lets you verify
Federal rules for cleaning contractors are thin; the expensive differences are state-level. What Washington charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Medical Lake labor cost are below with official sources.
Two free marketplace paths: one request brings back multiple vetted cleaning contractors who know they are competing for the account.
Washington taxes cleaning services only in part, and the split usually falls exactly where Medical Lake business buyers sit. Routine janitorial (windows, floors, walls/woodwork, rugs, dusting, trash) is not subject to retail sales tax - it is taxed under Service & Other Activities B&O at 1.5%/1.75%/2.1% by prior-year income tier.
Washington requires cleaning contractors to hold a state licence or registration - Not cleaning-specific. A state Business License and UBI is required if you use a trade name, will hire employees within 90 days, collect sales tax, gross $12,000+/year, or need city endorsements. - which gives Medical Lake buyers something most states do not: a public record to check before signing.
Washington janitors and cleaners earn a median of $21.89 an hour per federal wage data, which is the labor floor under every Medical Lake cleaning quote - labor is roughly the whole cost structure in this trade.
Most states do not license commercial cleaning companies, which surprises buyers who assume there is a board to check. What Washington does or does not require - and what that means for verifying a Medical Lake contractor - is set out below, with the state's own source next to it.
Cleaning is labor, and labor is priced locally. What Washington sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Medical Lake quotes than any vendor's sales pitch does.

What Washington adds to a cleaning contract
| Question | Washington answer |
|---|---|
| Sales tax on commercial cleaning | Partly - depends on the work - Routine janitorial (windows, floors, walls/woodwork, rugs, dusting, trash) is not subject to retail sales tax - it is taxed under Service & Other Activities B&O at 1.5%/1.75%/2.1% by prior-year income tier. Specialized or non-repetitive cleaning is Retailing B&O plus retail sales tax. (WAC 458-20-172) |
| Licence or registration required | Yes - Not cleaning-specific. A state Business License and UBI is required if you use a trade name, will hire employees within 90 days, collect sales tax, gross $12,000+/year, or need city endorsements. (Washington State Business Licensing Service (Department of Revenue)) |
| Median janitor wage (federal data) | $21.89 per hour |
| State minimum wage | $17.13 |
Washington is the trap state: routine janitorial escapes retail sales tax but still owes Service & Other Activities B&O on gross receipts, while one-off specialized cleaning flips to Retailing B&O plus sales tax - washing the windows is untaxed, washing the exterior walls is not.

Why Washington rules move Medical Lake quotes
Two of the three state variables land directly on your invoice. Sales tax, where a state charges it on cleaning services, is added to every monthly bill - on a mid-size contract that is real money over a year. The wage floor sets the labor cost every bid is built on, which is why identical buildings in different states get materially different quotes. Licensing is the third and it works differently: it does not change the price, it changes what a Medical Lake buyer can verify before signing.
What this means in Medical Lake
A certificate of insurance proves someone had coverage on the day it printed. It confers no rights on you, it does not obligate the insurer to notify you if the policy lapses, and the limits shown may already be partly consumed. Ask for the certificate from the broker, name your entity as additional insured, and re-request it at renewal.

Common questions
How do I compare two very different cleaning bids?
Normalize three things before you look at price: total cleanable square footage, frequency per area, and exactly which specialty services are inside the monthly fee. Most large gaps between bids disappear once those are matched - and the ones that survive are usually explained by staffing model or supervision, which is worth paying for.
What does 'bonded and insured' actually mean?
They are two different things and only one behaves like protection. Insurance - general liability, typically $1 million per occurrence, plus workers' compensation - responds to covered claims. A janitorial surety bond covers employee theft but pays only after the employee is criminally convicted, and the cleaning company must reimburse the surety afterward. It is closer to a credit guarantee than to insurance.
What does floor stripping and waxing cost?
Strip and refinish runs about $0.30-$0.80 per square foot in 2026 pricing, and scrub-and-recoat - the lighter maintenance version - about $0.20-$0.40. Most vendors apply a minimum service fee of roughly $250-$500, which makes small jobs disproportionately expensive per square foot.
Is it cheaper to pay hourly or per square foot?
Neither is inherently cheaper; they suit different jobs. Hourly pricing runs $25-$75 per worker per hour and fits small or irregular scopes. Square-foot pricing fits predictable routine work and makes budgeting easier. The only fair comparison is to ask every bidder for the all-in monthly total on identical scope and frequency, then divide.
How much does office cleaning cost per month?
For a small office cleaned three times a week, published ranges start around $100-$250 a month at the smallest sizes and run to $250-$800 for a few thousand square feet, with larger spaces at $350-$1200 and up. Restroom count, floor type and whether consumables are included move these more than most buyers expect.
