We are happy to use Mr Sun Oh soft wash Kolossus s service. The price was reasonable. He explained of the process clearly. He was responsible to keep me posted when he arrived, even not late much. Generously, he offered the special price when knowing my husband is Veteran. He was kind person to let us know what we had to do on the top of chimney...However it is better the price should be included of cleaning window in general, because after doing the roof our all windows were dirty.Thanks Mr. Sun Oh, our roof is now clean. We will recommend softwash Kolossus to our family/friends...

Kolossus SoftWash is amazing. This is the best way to clean siding, windows, and roof; no more pressure washing!Sun Oh was very clear on what to expect (except he failed to mention washing the windows as part of the basic service in his estimate, bonus!). He was prompt, thorough, and kept me well informed of what was happening and why. He even treated the moss growing on my shed roof, which wasn’t part of the original job description (bonus # 2!).Tony Kim was respectful, intelligent, and helpful. The extra care he took to protect our plants and property was evident and appreciated.

Great service with very professional and very advanced equipments complying with all the laws, regulations, and environmental compliance. Highly recommended!

Not only does he provide great service, he shows you the before and after meter levels. Whether it be for proactive treatment, or reactive due to a positive COVID case in the office, Sun will take care of you and your business!

I highly recommend Sun of Kolossus SoftWash. Pristine customer service. Fast AND reliable service. Kolossus SoftWash provides peace of mind that everything is disinfected...especially with covid19 around. Their hand sanitizer is also amazing and doesnt dry my hands out!

I have worked with Sun Oh at Kolossus Softwash several times and I give him my highest possible recommendation! He is amazing at removing moss from roofs and driveways - I refer him to all my friends and family!
