How Much Does Office Cleaning Cost in Seattle in 2026?

Commercial office cleaning in Seattle costs $0.10–$0.25 per square foot per visit in 2026. For a small office (1,500–3,000 sq ft), that's roughly $150–$450 per visit, or $600–$2,500 per month on a recurring schedule. Here's what drives the number and how to compare quotes.

Average office cleaning prices in Seattle (2026)

• Per square foot: $0.10–$0.25 per visit (smaller spaces sit at the higher end — minimum visit costs apply)
• Small office, 1,500–3,000 sq ft: $150–$450 per visit
• Mid-size office, 3,000–8,000 sq ft: $350–$900 per visit
• Monthly contract, small office cleaned 2–3x per week: $1,200–$2,500
• One-time or post-construction cleaning: typically 2–3x the per-visit rate

What's included in a standard office cleaning?

• Trash and recycling emptied, liners replaced
• Restrooms fully sanitized and restocked
• Kitchen and break areas cleaned — counters, sinks, appliance exteriors, tables
• Desks, conference tables, and high-touch points (handles, switches, elevator buttons) wiped
• Floors vacuumed and hard surfaces mopped; entry glass cleaned

What affects commercial cleaning prices?

• Frequency — nightly service costs less per visit than weekly, because less builds up between visits (see our guide on how often a small office should be cleaned)
• Restrooms and kitchens — these take the most labor per square foot; an office with four restrooms costs more than one with one
• Floor types — carpet-heavy offices need more machine time than sealed concrete
• After-hours access — evening and weekend service is standard, but strict security protocols add coordination
• Foot traffic — a client-facing office holds a higher standard than a back-office space

Contract vs. per-visit pricing: which should you choose?

Monthly contracts price 10–20% below equivalent per-visit rates and guarantee your slot — the right call for any office with a fixed schedule. Per-visit pricing suits seasonal needs, one-time deep cleans, or a trial period before committing. A reasonable middle path: start per-visit for a month, then convert to a contract once the scope is dialed in.

How to compare office cleaning quotes

• Insist on a written scope — "general cleaning" means something different to every company
• Verify insurance and bonding, and ask whether staff are employees or subcontractors
• Confirm supplies and equipment are included in the price
• Check recent Google reviews from commercial clients specifically
• Ask how quality issues are handled — a re-clean guarantee separates professionals from the rest

Frequently asked questions

Is office cleaning done during or after business hours?

Usually after hours or early morning, so the team never disrupts your staff. Daytime service works well for low-traffic offices and typically costs the same.

Do we need to provide supplies or equipment?

No. Commercial teams bring everything, including consumables like liners, paper products, and soap on restocking plans.

Is there a minimum contract length?

At Sensational Cleaning, no long-term lock-in is required — most Seattle clients start monthly and stay because the results hold, not because a contract forces them to.

Do you serve offices outside downtown Seattle?

Yes — we clean offices across Seattle, Bellevue, Kirkland, Redmond, Bothell, and Lynnwood, including business parks and medical or professional suites.
