Amazing Reviews
EXCELLENT Based on 490 reviews Posted on Stephanie ParkerJanuary 16, 2026Trustindex verifies that the original source of the review is Google. We have hired Cornerstone for roof and gutter cleaning at.two different properties in Kitsap County over the years. They do excellent work and use effective safety practices. I also like that our property has always been completely cleaned up when they’re finished. I did notice their prices have gone up substantially since the last time we used them. But I did not shop around because I trust this company to do a good job safely.Posted on Sherri EgashiraJanuary 13, 2026Trustindex verifies that the original source of the review is Google. Easy scheduling. Gutters were cleaned, Christmas lights removed. All debris including that wasn't even in the gutters, like fallen leaves on the back porch, were cleaned up. Very tidy.Posted on Jason StolbergJanuary 11, 2026Trustindex verifies that the original source of the review is Google. All good work, very fast and courteous.

A minor hiccup in that they came without all the equipment needed but explained the problem, rescheduled and did a great job. Have used them several times and will continue!Posted on Michael BruneauDecember 17, 2025Trustindex verifies that the original source of the review is Google. Cornerstone made things rights. I was initially disappointed by the service due to the amount of debris that was left by the roof cleaning service. However, upon hearing my complaints, Cornerstone responded immediately and sent out an experienced worker to get the job done right. I really appreciated the way Cornerstone did everything they could to make me feel good about the service and I will use Cornerstone again.Posted on Bob MDecember 10, 2025Trustindex verifies that the original source of the review is Google. Excellent work completed, courteous and professional. I will use Cornerstone for many years to come!Posted on Sundae DelgadoDecember 10, 2025Trustindex verifies that the original source of the review is Google. This morning I had my exterior windows cleaned by Cornerstone Cleaning, and I am absolutely thrilled with the results! Right from the start, their professionalism was evident. They arrived on time and were clearly highly skilled in their trade. They worked efficiently and meticulously, paying attention to every pane and corner. The difference they made is astonishing. My windows are now crystal clear—in fact, they are so clean, it barely looks like there's glass there! What truly made the experience exceptional, however, was their attitude. Michael and Kevin are incredibly personable and friendly. Their smiles were as bright as they made my windows, adding a genuinely pleasant touch to their excellent service. If you are looking for exterior window cleaners who deliver impeccable results with a fantastic, professional, and friendly demeanor, I wholeheartedly recommend Cornerstone Cleaning.Posted on Cindy HarrisDecember 8, 2025Trustindex verifies that the original source of the review is Google. Cornerstone dressed two of my evergreens with little lights, and did a great job. They were efficient, friendly, on time. A nice experience, and I'll call them again!

House Washing Frequently Asked Questions
What is house washing and why is it important?
House washing uses a soft wash approach (low pressure + specialty cleaners) to safely remove algae, mildew, dust, and grime from home-exterior surfaces without damaging siding, paint, or trim. It improves appearance and helps protect exterior materials.
How often should I have my house washed?
Most homes benefit from house washing once every 1–2 years, but homes in shaded or moist areas may need it more often to prevent buildup and staining.
Â
Â
Is soft washing better than pressure washing for siding?
Yes. Soft washing gently removes organic growth at the root level without the risk of water intrusion or surface damage that high-pressure washing can cause on siding materials.
Will house washing remove mold and mildew?
Absolutely. Proper soft washing uses cleaning agents that kill and remove mold and mildew, not just streaks on the surface.
Do you protect landscaping and outdoor features during house washing?
Yes. Professional house washing includes protecting plants, outdoor fixtures, and sensitive areas using eco-safe techniques so your entire exterior is cleaned without collateral damage.
Why does my house get green stains so fast?
Green stains are algae caused by moisture, shade, and airborne spores. Washington’s climate accelerates this growth.
Â
Is house washing the same as pressure washing my siding?
No. House washing uses a soft washing method that relies on low pressure and cleaning solutions to avoid siding damage.
Â
Â
Can house washing remove mold, not just surface stains?
Yes. Soft washing treats mold and mildew at the root level, not just what you can see.
Â
Â
Will house washing damage my paint or siding?
No. Professional soft washing is designed specifically to protect paint, vinyl, and composite siding.
Â
Â
How often should I wash my house in Western Washington?
Most homes benefit from house washing every 12–18 months due to moisture and algae growth.
Â
Does house washing help prevent long-term damage?
Yes. Removing organic growth prevents moisture retention that can lead to rot, staining, and siding deterioration.
Â
Should house washing be done before or after roof cleaning?
Roof cleaning is usually done first so runoff does not re-dirty clean siding.
