"100% recommend this company if you have moss growing on your roof. They went above and beyond my expectations."

- Tyson P, Bellingham

"Hi Taylor...just wanted to say your 2 guys were awesome today. What polite, hard-working, diligent individuals. Very impressed with them and the first class service your operation provided from beginning to end. A fair price and top notch all round. We'll be telling our neighbors for sure. So nice to have clean windows! We'll be back for more! Thank you.

Northwest Window Cleaning-Icon-Home-Blac

We offer a wide range of both residential and commercial window cleaning services. We use pure water solutions and low soap concentrates that keep our footprint extremely low while at the same time leaving your windows spot and streak-free! We are available for both single and scheduled cleanings. Clean windows not only look great, they are also important for the longevity of your windows. 

Northwest Window Cleaning-Icon-Water-Bla

Our professional roof soft wash cleaning service safely removes all organic growth from your roof including: mold, mildew, black streaks, and moss. Organic growths like these left untreated take years off of the life of your roof and can lead to costly repairs if the water diversion system of your roof is compromised. We follow ARMA (asphalt shingle manufacturers) guidelines to treat your roof. 

Northwest Window Cleaning-Icon-Gutter-Bl

Maintaining your gutters is a great, generally inexpensive way to prevent some serious problems for your home. Dirty, clogged, or overflowing gutters can lead to foundation and landscaping erosion, water back flowing into your home, ice dams, falling gutters, moisture on siding and roof eaves. We most often hand scoop gutters and then finish with a water rinse out.
