5 Best Commercial Cleaning Services in Seattle (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 7 min read

Finding a Seattle cleaning company for an office or commercial space is harder than it should be: most businesses that surface in this search are built around homes and apartments rather than offices. Ladonna's Cleaning Service has over 25 years in business and Meekas Cleaning Services holds a perfect 5.0 rating, and both explicitly list commercial cleaning among their services, so start there if the job is a business, not a house.

Short answer: Maid Service Seattle is the most-reviewed cleaning business in this search at a perfect 5.0 across 346 reviews, but its evidence is entirely residential. Ladonna's Cleaning Service (4.7, 303 reviews) and Meekas Cleaning Services (5.0, 66 reviews) both explicitly list commercial and construction-site cleaning, making them the closer fits for an office or business job.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other Seattle-area cleaning businesses. Confidence weighs the rating by that volume, so a 5.0 from hundreds of people carries more weight than a perfect score from a smaller base. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does commercial cleaning cost in Seattle? (2026)

Commercial cleaning pricing depends heavily on square footage, frequency, and scope. General guidance based on typical job factors:

What to ask before you hire a commercial cleaning company

Do you have experience cleaning offices or commercial spaces specifically, not just homes?

Is the crew insured and bonded for commercial properties?
Is pricing based on square footage, frequency, or a flat contract rate?
Can cleaning be scheduled after business hours?
Do you supply your own cleaning equipment and supplies?

Frequently asked questions

How did you choose these commercial cleaning services?

We started from every cleaning business returned in Seattle’s commercial cleaning search results with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Are these businesses actually commercial cleaners?

Mostly not. This search returned residential house and apartment cleaning specialists, with Ladonna’s Cleaning Service and Meekas Cleaning Services the only two that explicitly list commercial, office, or construction-site cleaning among their services.

Which business should I call for an office cleaning job?

Ladonna’s Cleaning Service has the clearest reviewer evidence of real commercial work, including a same-hour business event cleanup. Meekas Cleaning Services also lists commercial cleaning but currently has mostly residential reviews on file.

The bottom line

Ladonna’s Cleaning Service is the strongest evidenced pick for a genuine commercial or office job, with over 25 years in business and a reviewer describing real commercial floor cleaning. The other names on this page are well reviewed but are residential specialists, so confirm commercial experience directly before booking.
