"Best window cleaning service in Lake Oswego, hands down. I've tried three other companies. None of them came close. My windows look brand new and there wasn't a single streak. Already booked them again."
"Had them do the windows and pressure wash the driveway. Both came out perfect. They were on time, professional, and done in two hours. Worth every penny. Highly recommend for anyone in Beaverton or Tigard."
"I was skeptical at first but they delivered. I have 22 windows in my Portland home and every single one was spotless. They also cleaned the screens which I didn't expect. Incredible value."

Yes. Cascade Window Co. is fully insured for all residential service throughout the Portland metro area. You're protected on every job.
Portland's climate — rain, pollen, and seasonal dust — means most homeowners benefit from 2–4 cleanings per year. Spring (after pollen season) and fall (before winter rain) are the most popular. Homes near trees or with high traffic may need it more often.
Nope. For exterior-only service you don't need to be home at all. For interior window access we'll coordinate a time that works for you. Either way, we'll send you a confirmation when the job is complete.
