Fast COVID Disinfecting & Sanitizing Services

Ensure your hospital, manufacturing facility, warehouse, restaurant, or other commercial space is COVID-free.

Our commercial office cleaning team uses electrostatic foggers from Clorox and Victory to disinfect every surface in your facility. Additional hand-wiping by our PPE-equipped cleaners further sanitizes high-touchpoint areas like phones, doorknobs, and shared surfaces.

Our sanitation methods are CDC and EPA-approved for your safety and peace-of-mind.

FREE facility surveys available! Call (503) 850-0357 today.

Your office’s appearance matters. It sends a powerful message to your customers and clients, and it also serves as a place for your employees to do their best work. If your office is dirty, dusty, disorganized, or otherwise unclean, you’re letting down your customers and your employees. If you neglect your office’s cleanliness, your business will suffer because of it.

At Cascade Building Services, we’ve been cleaning office buildings throughout the Portland area for over 50 years. Our company is the office cleaning agency that knows what it takes to make your office’s first impression a great one.

Our Office Cleaning Services

Janitorial Services


The keys to keeping an office space clean are consistency and attention to detail. Our janitorial services team can provide both. Whether your office requires a monthly deep cleaning, weekly touch ups, or daily service, we’ll create an office cleaning package just for you.

Office Carpet Cleaning Services

Commercial Carpet Cleaning

Your employees and your customers walk across your carpets every day of the week. That leads to plenty of wear and tear, which can reduce the lifespan of your carpet– unless you clean them regularly.

Our carpet cleaning team uses an eco-friendly and biodegradable carpet cleaner that leaves no residue behind and won’t trigger asthma or allergy attacks.

Window Cleaning Services

Clean Windows

You shouldn’t notice your windows. If you do, then they’re not clean enough. Your office’s windows should be crystal clear and free of streaks and smears. In Portland, our rainy weather can build up a tough layer of grime unless you clean your windows frequently.

We use an eco-friendly and biodegradable window cleaner that leaves behind glass that’s simply sparkling clean. In addition, as part of our window cleaning service, we’ll also make sure your window sills, tracks, and ledges are clean, too.
