What Our Clients Say

We are proud to partner with local businesses that value cleanliness and professionalism. Here's what some of our clients have to say about working with us:

Whatcom Janitorial has been cleaning our office twice a week for several years now, and always does a great job. They're attentive, flexible, and easy to work with. They also do a great job communicating when issues arise, supplies run low, or if you're extra lucky, your upstairs neighbor's pipes freeze and an unplanned water feature develops overnight (we heard from Whatcom Janitorial's team before our property management). Thank you for years of good work!

Tyler Sokanoff

Compass Real Estate

If you are looking for some awesome, knowledgeable people to work with, these are the guys I highly recommend. Their friendliness and result-driven approach is what I love about them.

Steve Kirk

VP Of Finance @ Woodstone

Whatcom Janitorial has been providing us with their services for about two years and we are very pleased with them. They are friendly and efficient and do a wonderful job. We would highly recommend them!

Cathy Witney

Residential Client

Great business partner. Very responsive and customer focused. I’ve been working with them for years. Reasonably priced, always open to customer feedback and making adjustments when needed.
