Great Experience. They had a modern interface to quickly generate a quote and get me an appointment to clear moss off my roof. They showed up on time as promised and did a great job.

Cornerstone does a fantastic job on both gutter and window cleaning. They are easy to book and work quickly and professionally. I will hire them again!

The work was done well, but one of our plants was damaged by a ladder which was not ideal.

Cornerstone was very prompt, professional, and quoted a good price. I arranged a gutter cleaning without realizing my metal roof was really slippery and gross with algae. I really give these guys credit trying to navigate it. They did a great job and I'm definitely going to have them back next year for the full roof wash plus the gutter cleaning. Thank you!

I have to start by saying, I never write reviews but I am just that impressed by this company!I recently had my gutters cleaned, skylights washed and moss removed off of the roof of my property. I was very impressed with the level of professionalism from scheduling to getting the job done. They were right on time and provided an exceptional service! The gentlemen that came out were incredibly friendly and went over every detail with me so I would be informed of what they were going to do. I was stunned at how good of a job they did! I've never seen my roof as clean as it is now. They even cleaned up all the debris that fell and cleaned my entire driveway! It is rare these days to see companies that work with such integrity. I could tell they really care about their customers. I referred them to all my neighbors and highly recommended to anyone looking for home maintenance. Thank you Cornerstone Cleaning!

We have had a lot of rain and noticed that our downspouts and gutters appeared to be clogged. I contacted Cornerstone and they gave me a reasonable quote and a date within a week of my first contact. The young men who did the work were polite, pleasant and professional. The area around the house was cleaned and I'm extremely happy. I will definitely be using Cornerstone in the future!

I've use Cornerstone Cleaning for a couple of years now and have always been impressed with the size of their teams -- the quality of their work and their professionalism. We've got a very large number of windows -- some QUITE high to reach both inside and out. They handled them with no problems. I will definitely use them again next year!

My front and back deck look brand new .They both were filthy and now they’re sparkling clean thanks to them. I’ll definitely give them my business again in the future. Thanks cornerstone !

Cornerstone did a professional job in cleaning and treating my roof. Blew all the roof debris off the concreate and deck. Three guys showed up, checked in, and let me know when they were complete.

The service team was professional and completed the job in short order! They did a great job of cleaning out the gutters and then followed up with a good clean-up of "fall out" on windows, siding, deck and patio surfaces. They did such an excellent job, we decided we will be using them for gutter services in the future and are contemplating taking advantage of other services they offer.

We had Cornerstone Cleaning provide gutter cleaning and exterior window cleaning. Working with them was so easy! Their communication was quick and helpful, even when I had them add in window cleaning after the initial quote. I had two other bids for the same work and theirs was the best value. The service was great and I was left with clean gutters and windows. Thanks Cornerstone Cleaning!

Professional job, they cleaned the gutters, roof and washed the windows. The wait list was long, really long - but it was worth the wait.

Theresa Cole

My windows are sparkling clean. The provider was especially careful around all my foliage, and left an immaculate work site. He was cheerful, took pride in his work, and provided excellent service. I will recommend highly to all my friends and colleagues.

Cornerstone Cleaning provided great service. They were responsive, providing a quick quote for removing the moss from and treating my roof. Two worker bees (Kyle and Nick) arrived as scheduled. They worked quickly to remove the moss and debris and then applied their treatment to inhibit it’s regrowth. After all the moss and debris was on the ground, they proceeded to clean up the affected area and actually left it cleaner than it was before they started. I would definitely recommend.

I had Cornerstone (formerly Kitsap Moss) power wash my metal roof, gutters, and siding and they did a splendid job. Everything was pretty filthy/grimy from a few years of build up, but it looks great now. The crew was very friendly and professional and knowledgeable about the work that needed to be done. They had a great attitude and took the time to explain some of the work issues to me in a way that helped me understand and learn more about my roof, etc. All contacts with the office were also professional and helpful, with questions and issues being resolved very quickly. I recommend them without hesitation.

Cornerstone Cleaning cleaned my gutters recently, and I have been working with them for years, referring several friends who have hired them for roof / gutter cleaning, window and power washing. They are always professional, and really good at what they do! Ryan is amazing and truly cares about his customers. The crew was very polite and did a wonderful job!
