Amazing Reviews
EXCELLENT Based on 505 reviews Posted on LR SourceMarch 28, 2026Trustindex verifies that the original source of the review is Google. The crew was friendly, efficient and did a nice job. The house looks great!Posted on katy knutsenMarch 25, 2026Trustindex verifies that the original source of the review is Google. Excellent experience start to finish! I sent a request for a quote on Sunday and made a note on my calendar in case I didn't hear. Received a" thank we will get back to you in 24 hours" email. I had an email and a phone call by 10 the next morning. I explained I would like to be there or talk to the estimator. Brian called me about .20 minutes later. I explained what I was hoping for and I had an estimate by that afternoon. Easy to read with options for add ones if I should choose. I marked what I wanted and had an appointment by end of day for them to perform the work! I was given an option to have an earlier appointment 2 days later which I declined. Communication was excellent through the whole process! Guys showed up today, worked hard and my roof looks beautiful as my gutters and the outside of my windows! They worked right along, tidied up very nicely and were on their way. Polite, clear communication. I would absolutely use Cornerstone again!Posted on Leah OsowkiMarch 23, 2026Trustindex verifies that the original source of the review is Google.

On time done rightPosted on Karen KimzeyMarch 17, 2026Trustindex verifies that the original source of the review is Google. They showed up on time. Everyone was courteous and professional. It's our second time using them and we will gladly use them again in the future.Posted on Steve DeliganMarch 13, 2026Trustindex verifies that the original source of the review is Google. UPDATE TO ORIGINAL POST: The next day the company sent out one of their supervisors to clean up the job from the previous day. He ended up having to repeat the entire job, by hand, by himself. He was here for almost five hours rectifying all the weirdness from the first day. It looks fantastic now! It’s sad that they had to do the job twice. The house now looks great and like it should have the first time. We had to spend an entire extra day ourselves hanging out at the house and making calls and making sure it all worked out instead of our other obligations. We now have to bill the estate for an extra day of our time. ——————————- Original post: Frustrating company to work with. PROS: The two-person crew showed up on time. The lead guy was great. He worked hard and knew what he was doing. He pressure washed until the equipment failed. CONS: The second guy in the crew was supposed to wash the windows. He missed several windows altogether. Completely forgot them. Then on about half of the others he did really poor job and we had to have them back out. He also did NOT wipe up the drips on the window sills from his squeegee! It was weird because we showed him the water and he said “Oh… yeah… ok” and then immediately forgot to wipe up the rest. See my picture. About twenty window sills all were left muddy. Honestly, it was weird of him not to simply run a towel over them. In the end, we could tell the windows that he had forgotten altogether by the fact that there was no mud left on the sills (and because they were still dirty). Then in the master bathroom he had to stand in the tub to get to the window but then left dirty drips all over the window sill and the tub. I feel sorry for the poor guy that he isn’t able to clean windows properly but we’re also paying a lot of money to get the house ready for sale and now have an extra job to line up. Secondly, the lead guy who was working really hard also had to deal with the broken-down equipment that the company makes him use. We felt bad for him and the company should spend a bit more on their equipment and perhaps a bit less on their branded trucks. The pressure washing blasted a bunch of dirt up into the outside walls which wasn’t cleaned up. The lead guy also felt bad because we asked him if he could pressure wash the porch (small area that apparently wasn’t part of the original estimate) and we said we would obviously pay for it. He said he had time but wasn’t allowed to by company policy until another estimator came out to price the job. Lead workers should be able to make small adjustments to the jobs while on site. It would mean more money for the company and avoid two additional trips (one for the second estimate and one for the small job). This guy was more than capable of giving an accurate estimate and the company should respect his judgment. This isn’t his fault. We picked them based on a recommendation from our realtor. She said that this level of poor job is unusual from them but couldn’t believe the pictures we showed her. Overall we really liked the lead guy, but the second guy can’t clean windows and the company responses have been frustrating. It wasn’t until after we sent pictures that they agreed that the job was not completed. Will update after their second try.Posted on Bryan ForemanFebruary 26, 2026Trustindex verifies that the original source of the review is Google. Crew showed up on time and completed and cleaned up the work areas. Also had them clean the solar panels.Posted on C HoltmeierFebruary 23, 2026Trustindex verifies that the original source of the review is Google.

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.
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.
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.
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.
Will house washing damage my paint or siding?
No. Professional soft washing is designed specifically to protect paint, vinyl, and composite siding.
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.
Does house washing help prevent long-term damage?
Yes. Removing organic growth prevents moisture retention that can lead to rot, staining, and siding deterioration.
Should house washing be done before or after roof cleaning?
Roof cleaning is usually done first so runoff does not re-dirty clean siding.
