How we build these lists

Every city list on this site is built from public Google Maps business data, pulled on October 22, 2026 through the DataForSEO Business Listings API.

Which companies are included

• Listed on Google as a janitorial, commercial cleaning or office cleaning service, within about 25 km of the city center (35 km for Los Angeles, where too few companies met the bar within 25 km).
• Not marked as permanently or temporarily closed.
• At least 5 Google reviews and an average rating of 4.0 or higher.
• House-cleaning-only, carpet-only, pressure-washing, staffing and supply businesses are removed.

How they are ordered

By number of Google reviews, highest first. We do not test or inspect any company, and a listing is not an endorsement.

Advertising disclosure

No company pays to be listed or to be ranked higher. When you submit a quote request, we pass it to partner commercial cleaning companies that serve your area, and we may be paid by those partners. Partner companies may not be the companies shown in a city list.

Corrections

Company details come from each business's Google listing. If a detail is wrong, update the Google listing and the change will appear on our next refresh.
