“It has been an honor to work with Cascade Building Services. When you find a company that truly cares about their customers and employees, you have found substance and quality.

I love the fact that I can use them as a one-stop shop for commercial and residential janitor service, landscaping, window cleaning, monthly maintenance, and tons more. Five stars.

“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!!

“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.
