  • Kirill and his team are amazing. They were able to help me on short notice and outperformed my expectations.


    I felt like they really respected our belongings during the clean-up. When I wanted an heirloom saved, Kirill did his best to make sure it was safe to keep it. That meant a lot after already losing so much due to vandalism.


    Kirill was also very helpful in getting my insurance company to pay for the work--even though my insurance company wanted to use another provider.

    I recently had the pleasure of doing business with Kirill. He was very knowledgeable and patient with the questions I had and walked me through the process of what needed to be done at my property. I was very happy with Kirill and his team members and the thorough work that was done. I would highly recommended Kirill and his team. Thank you so much for being, patient, kind understanding, sensitive to our needs.

    I used Kirill for a partial clean out - that is, a friend who had a problem with hoarding and was being hospitalized for a short time. Her family wanted to organize and sanitize her home before she returned.

    Kirill took on this relatively small job and was very sensitive to the situation.


    They were thorough, organized and respectful- could not have asked for service more professional. They referred a carpet cleaner and provided a housekeeping service to put the final touches on the job.

    Thank you!

    Kirill and Mike did an outstanding job on our project in San Francisco (cleaning and decontaminating a basement and detached garage following a rodent infestation). They arrived on time, did an extremely thorough and professional job using all the right equipment and tools, and were extremely professional. They even took the time to do a few things that were outside their scope, such as clean and disinfect an armoire that was stored in the garage. Their work and clean-up were immaculate; the spaces are not only decontaminated but spic and span. I could virtually eat off of the floors.

    We discovered a mold issue in our master bedroom as we were doing drywall repair. I requested a quote from a few companies and Kirill responded immediately and provided a free estimate within 24hours. Other companies wanted to charge for an estimate. Him and his team completed the mold removal  in 1 day and left our room cleaner than when they arrived.   We were very pleased with quick response times, professional  service, and honesty.
