lori-wills“Cascade Building Services did a great job buffing our floors at our Hair Salon in Scappoose. Our floors had lots of buildup from us not cleaning them properly.

Our floors are restored to their new appearance. Can’t thank them enough for a job well done!!”  – Lori Wills

Matthew Sangster Testimonial“I’ve been working with Cascade for a little over 15 years. They are the janitorial service we use in our retail stores in the Portland Metropolitan Area. They are extremely thorough and amazing customer service.

They are available at any time with any concerns, and I’ve never had any. I would highly recommend their services.“- Matthew Sangster
