Bio 911

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.

Amazing job! Quote was half the price of another quote we got. They tackled a home that had 20+ years of hoarding and a rat infestation that was worse than anything I'd seen on the TV show. They did an amazing, professional job. Great communication. Couldn't have been a better experience given the nature of the problem.

Kirill called me back, set up the appointment, came on time, fixed it within 24 hours. Easy to work with, professional, efficient, thoughtful. Less expensive than I thought it was going to be.

Awesome.

Kirill was very professional and courteous, identified and clearly explained problems and offered suggestions on solutions even when they weren't related to services that his company provides. I'm looking forward to working more with Bio 911 in the future!

Kirill was very responsive and very professional. He fit me on a very time tight schedule to check my home for mold.
Was very generous with advice, highly recommended, and would definitely be contacting him again for further work when needed.

We highly recommend using Kirill for your mold issues. He knows his stuff, is quick to schedule an appointment, is fast and thorough with follow-through. He does not over-dramatize the possibilities or try to up-sell you. We appreciated how he insisted on waiting until test results were available (only a couple of days) before suggesting a treatment plan. He educated us on how to treat the mold ourselves but also would have treated it for us. My husband has dealt with other mold remediation companies through work and ranks Kirill as the best he has encountered. He will be using him for future business projects.

Today I had the pleasure of meeting Mr. Kirill with Bio 911 to do mold testing. He was very efficient. I explained what was going on and how nervous I was. He began testing and found no moisture. Needless to say I was beyond happy to learn that there was no mold. And immediate relief and to top it off there was no charge for the inspection. Mr. Kirill was very professional and easy to Communicate with. I would definitely recommend this company to friends & family.

Bio 911 contacted me on the phone to help me with an issue I was having with my bathtub. They guided me through how to fix the issue myself and were super helpful and friendly. I would contact them again if I need help in the future.

Due to concerns regarding a moldy smell coming from three windows in my home, I contacted Bio911 (https://www.bio911sf.com/). Kirill Mendelson came out the same day that I called and tested the walls around the windows that are giving off a moldy odor. I was ecstatic to learn there is a device that can determine moisture content of walls and that no walls needed to be opened. He found the moisture content to be between1 and 4% and said anything under 10% is not a concern. Kirill suggested that since we have had such a wet winter that I may be experiencing an off-gassing causing some odor. He suggested using a product called Concrobium to clean around the window sills. If I experience any health issues, testing of the air can be done to determine what mold spores may be causing a problem. There was no charge for the inspection and I found Kirill to be very informative, easy to schedule with, professional and as nice as could be. Bio 911 offers cleanup of extreme situations in addition to mold testing and remediation. I will contact BIO 911 in the future should I need any of their services.

Speedy service, good communication, clear quote. Individuals who conducted the work were courteous, punctual, and left the worksite clean. ​​​

I was unfortunate enough to have a serious infestation of rats under the house within a year after having the crawlspace completely cleaned up and a thick moisture barrier installed. Well my neglect for just over a year allowed quite a bit of damage, mostly droppings and urine.

I had Spaulding come out clean up the droppings and urine, pull down any floor insulation which looked like the rats had been busy in those areas.

I was expecting a lot of insulation to be removed but Kirill was very honest and indicated much of the insulation didn't require being removed and ultimately replaced saving me those extra costs. The job was done in a shorter period and the quoted cost reduced. Honesty and quality work. What more could one ask for when hiring a contractor.

I would highly recommend Spaulding for your clean up.
