How this list was made
We pulled 220 Bellingham-area commercial cleaning companies from Google Maps, then kept the 8 with a rating of 4.0 or higher and at least 10 reviews. The average rating in this group is 4.70 stars.
Ratings with only a few reviews are pulled toward that average, so a business needs a real track record to reach the top. Nobody pays to be here. Read the full method.
