Sound ProWash is a family-owned exterior cleaning company serving Western Washington since 2015.
We believe in:
We’ve invested in modern softwash equipment, ongoing training, and systems that make the experience smoother for homeowners — from instant online quotes to organized job updates and consistent follow-through. But what matters most to us is something much simpler: earning your trust through the quality of our work. We’re a family-run company, not a franchise. The people who show up to your home take pride in representing our name, our workmanship, and our community. Whether we’re cleaning a roof, washing a home, or maintaining a long-term customer relationship, we approach every job with professionalism and respect.
Our goal is straightforward:
make it easy to feel confident choosing us.
If you want a dependable team who shows up prepared, communicates clearly, and treats your home like it truly matters, we’d be honored to work with you.
No. This is actually the way the manufacturers recommend having these exterior surfaces cleaned, whether it’s the roof or siding.
Our softwash method will not only help protect the home from high-pressure water intrusion, but it also allows us to reach higher peaks without needing to stand on ladders as much. That means:
We perform full property protection before starting any project and mask off all electrical components. We also offer caulking services before house washes, so we don’t get unnecessary water behind your siding.
Pressure washing and softwashing are two completely different processes.
For surfaces like asphalt roofs, tile roofs, house siding, and many metal roofs, we:
We never pressure wash roofs. Softwash is the manufacturer-recommended approach for those delicate surfaces.
The rule of thumb is 3–6 months, depending on:
We give you a 1-year guarantee to ensure that all of the moss has been treated.
What to expect:
It depends on your property. Every location is different based on:
Typical timelines:
With our treatment, you are paying for a 100% kill ratio of all organics. After that, Mother Nature determines how fast it comes back.
We give a 12-month guarantee to ensure a proper treatment. But because the variables (trees, shade, weather) are unknown, we do something better than long “warranties”:
There’s nothing worse than a 3–5 year warranty where you wait for visible damage to occur just to get a free service. That’s like trying to lose a dollar to save a penny.
At Sound ProWash, we believe preventative care is always cheaper in the long run. For years, we saw people doing treatments every 2 years, but by then the roof already had moss growing again and causing damage.
We use biodegradable, manufacturer-recommended treatments made up of:
These products are designed specifically for exterior cleaning and are used at the proper strengths according to the surface and conditions.
Yes, absolutely. Protecting landscaping is one of the core skills in softwashing.
Our approach:
Important note: Some customers try to cover plants with plastic before we arrive. This can actually
create an oven effect in the sun and cook the plants. We’ve found it’s better to hydrate them before, during, and after treatment.
If you are particular about your plants, we recommend you water them before and after our service. Rest assured, we have many tricks for protecting landscaping from roof softwash overspray — it’s literally a major part of our craft.
Yes, absolutely. Protecting landscaping is one of the core skills in softwashing.
Yes. The black stains usually come off almost immediately.
The black streaks you see are a type of algae formally known as Gloeocapsa magma. It’s typically the first sign of organic infestation on your roof.
If we nip it in the bud early with a proper roof softwash, we can:
You do not need to be home during the cleaning.
We just ask that you:
We do prefer, when possible, that you’re available to walk the job and approve the work at completion. If you aren’t there, you’re essentially trusting our final result — which many customers are comfortable with.
We also honor a 72-hour window:
Payment:
It depends on the service and the property, but the majority of our projects are completed in about 3–8 hours, depending on the scope.
For commercial projects, we are able to work outside normal hours as needed.
Whatever the job entails, we prioritize:
Our schedule is normally:
Sometimes additional trucks can pick up spur-of-the-moment projects, especially for smaller or more urgent jobs. We’ll always do our best to work with your schedule.
A little rain does not hurt our product at all.
Rain can even be helpful: it often protects plants by providing extra dilution and rinsing.
However, if it’s full-on downpour conditions, we may choose to reschedule for safety and quality reasons.
We’ll send you a courtesy checklist by email with everything you need to know to have the smoothest service possible.
In general, it includes things like:
No. Gutter cleaning is a separate service.
We do this intentionally so we can:
Our roof debris/gutter debris cleaning process is completely different from our softwash application process.
We highly recommend gutter cleaning when needed, and:
Some customers prefer to clean their own gutters or don’t get debris in them at all, so it wouldn’t make sense to charge everyone the same for that.
We always perform a meticulous debris cleanup of anything that falls off the roof or gutters from our process.
Depending on the situation, we may:
We leave the work area presentable and cleaned up.
We have completed thousands of projects and have never had a pet have problems with our treatment.
That said:
Out of courtesy and caution, we recommend:
In short: yes, it’s pet-conscious and handled with care, but we still suggest a little extra caution until surfaces are dry.
Yes. With our Roof Softwash service, we guarantee that 100% of the organics are treated and killed.
For metal roofs, we rinse the treatment off and they usually look clean immediately.
Yes. We are licensed, bonded, and insured.
At Sound ProWash, you are paying for:
We have a perfect insurance record with no claims, and we intend to keep it that way through:
We can provide certificates upon request:
(Insert link or “See certificates here:” for the web developer)
Initial roof cleanings typically cost about 5–10% of the roof replacement cost, depending on condition and how long the growth has been present.
With our 50% off annual treatment, you can:
It’s usually a fraction of what roof replacement would be — and it helps maximize the life of your existing roof.
Sound ProWash was established in 2015 and built on:
We aim to be your long-term roof and exterior cleaning partner, not a one-and-done crew.
We take pride in being one of the top-ranked companies in the state for true quality and professionalism.
Check out our reviews — they tell the story.
No. We take who we send to your home very seriously.
Customers consistently tell us they appreciate the peace of mind they feel with our crews from start to finish.
We do not come to your property trying to upsell you on random things. However:
Our goal is education and protection, not high-pressure sales.
Yes. This is our specialty.
Our approach is designed for:
At Sound ProWash, we are a premier service provider that competes on quality, with a fair price for the
level of service and protection we deliver.
Often, when customers tell us they found someone “half the price,” they also mention:
With Sound ProWash, you’re paying for:
We don’t cut corners. We price our services so we can pay all-star techs a livable wage and, in return, ask them for the highest level of service possible, so you can relax and feel confident in our work.
