Pacific Northwest ProWash is a professional company with quality services. Yesterday, their team soft-washed my roof and cleaned the gutters to my complete satisfaction. I will hire them again. Thank you!

Pressure Washing

The climate in the Pacific Northwest is the perfect breeding grounds for organic growth. We always implement a soft wash to sanitize your home’s exterior surfaces then pressure wash if necessary to unroot any major organic contaminants. This process prevents causing any unnecessary erosion to your property.

House Washing

House washing is a great way to sanitize and clean your home. Our process uses a low pressure detergent-based wash. We apply our soap solution to your home’s siding and let it dwell for 5-7 minutes. Then it is rinsed off with low pressure. This type of treatment is a safe alternative to pressure washing. This will brighten the exterior of your home for 2-3 years and will extend the life of your paint. A normal house wash will clean the exterior of the gutter line, the soffits, the siding, window sills, to the base of the home. This will get rid of unsightly bird droppings, green algae, cobwebs, spider droppings and brighten the exterior paint.

Roof Cleaning

Build up of moss on your roof can cause serious problems such as roof sinking, lifted shingles, and leaks causing wood rot. We follow the Asphalt Shingle Manufacturers Associations guidelines for soft washing roofs. We brush large organic material off first. Then, treat the roof with less than garden hose pressure with our soap. At the same time we will rinse down siding, windows, and plants to further mitigate risk of damage. Results typically last 3-5 years and sanitize the whole roof.

Gutter Cleaning

Involves cleaning out your gutter debris either with a leaf blower, with water, or by hand. Downspouts are then inspected to make sure they are flowing.

Gutter Guard Installation

Our stainless steel gutter guards offer a combination of the strength of expanded metal and the performance of a mesh screen to protect your gutters from pine needles, maple seeds, oak, ash tree tassels, and other small debris.

Window Cleaning

As a homeowner you know how stressful and time-consuming it can be to clean all the windows around your house. At Pacific Northwest ProWash, we can access any hard-to-reach windows and leave them shining, spotless and streak-free! You’re sure to be thrilled by how clean your windows are.

Deck and Fence Cleaning

Rain, wind, and a variety of environmental overhang causes organic matter to build up on your deck and fence. The mold, mildew, and moss collects, and then impacts the longevity of these surfaces and can cause slips or falls. It is important to maintain the quality of your deck & fence to avoid damages and expensive repairs. Whether it is a soft wash or a pressure wash Pacific Northwest ProWash has you covered.

Christmas Lighting

Why deal with tangled wires and climbing ladders? Let the team at Pacific Northwest ProWash take care of all your exterior holiday decorating needs. You won’t need to worry about extension cords, burnt-out light bulbs or any other annoying aspect of what should be a fun decorating project. We bring the lights, install them, take them back down in January, and then store them ourselves at our own facility. All you have to do is relax and enjoy basking in their glow throughout the holiday season. Don’t add the stress of rigging up the lights to the hustle and bustle of the holidays.

Frequently Asked Exterior Cleaning Questions

Got Questions? We've Got Answers

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.

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.

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.

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!

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.
