Luis worked hard and did a great job for us!Posted on Ron ReimerMay 2, 2026Trustindex verifies that the original source of the review is Google. Our roof is a steep, older concrete tile roof that is difficult to work on. The Cornerstone crew did an excellent job and the result looks great. I highly recommend them.Posted on Kenneth KraftApril 25, 2026Trustindex verifies that the original source of the review is Google. First session didn’t go so well. The gutters still had debris in them after the work crew had finished and left. I was not at home when the work was done during that first session. When I called and emailed my concerns to Cornerstone, they sent another crew out the next day and rectified the problem completely. The second crew did a great job. I would definitely use Cornerstone again, but I will visually inspect the finished work myself when they are done and before they leave. I applaud Cornerstone for responding so quickly to my concerns. I will continue to use them for my roof care needs in the future.Posted on Joan TenchApril 23, 2026Trustindex verifies that the original source of the review is Google. Good solid work! Thank you!

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.
