This is our second time using Pacific Northwest ProWash. Cole responded quickly and took a look at our job. We had the estimate the same day.

This was a huge job, and these guys worked non-stop all day to get the job done. Our home looks beautiful inside and out. We would never think about calling anyone else. Cole, Jen, Zack, and Donovan! Thanks so much - such a great team!!!
Whatcom and Skagit Exterior Cleaning
Pacific NW Prowash did an excellent job for me in Anacortes this week. They were able to schedule our job quickly, and even reschedule it when I had to change the time due to a conflict on my end. They came on time and finished as promised. The property looks like new. Thank you for your excellent service. And thanks specifically to Hayden who was friendly, professional, and did an expert job. Hayden is an asset to your company!
Exterior Cleaning Whatcom and Skagit County
From beginning to end, it was a great experience working with this company. They texted us that they were “on the way” and arrived right on time on the day of estimate and also on the day of project. We had our garage floor coating done which is new service they added. The crew Cody and Jack were efficient, on time and stayed long hours to finish our garage and we were very impressed with the thorough process and end result. We will definitely be using them again and would recommend them to our friends & family. Thank

Frequently Asked Exterior Cleaning Questions
Got Questions? We've Got Answers
Why is there still moss on my roof?
This is one of the most common questions we get as professional roof cleaners! That leftover moss should appear yellow/white in color, that means it is dead. The roots have been released from the shingle. It will turn to dust and blow away naturally in 3-6 months. We ask for you to wait 6 months before calling us for a warranty retreat. That is how long it usually takes to actualize 100% of the results from the treatment. This process is the safest way to clean a roof and protect one of the largest investments on your home.
What is Soft Washing?
Soft washing is best compared to cleaning your car. You have to use soap, not pressure to clean or sanitize it. Soft washing applies the same principles. A detergent is used to lift staining which allows for a low pressure rinse. Soft washing is more effective and efficient than conventional pressure washing. It cleans, santizes, and brightens your property without having to use high damaging pressure.
Do I Have To Put A Card On File?
We require a card on file. In the event you are unable to do so we require a check prepared for us to be collected on-site upon completion of your service. Payments are due upon completion of the work.
Do You Offer A Warranty?
Absolutely! We pride ourselves in the way we treat our customers and employees. This means if there is an issue we jump to fix it! We strive to be perfect every time but just like everyone we aren’t. That’s why we offer a 1 year warranty on asphalt shingle roof cleaning. If you see any organic green staining come back within 1 year of our service we will come right back out to fix it!
How Much Does It Cost?
We formulate all of our quotes by performing an onsite estimate, measuring the property, and seeing the level of staining and/or growth. It’s too difficult to quote over the phone with too many unknown variables. Seeing the jobs in person helps gather enough data to set your expectations correctly so that there aren’t any surprises. What we can give you on the phone today is our minimum pricing.
