Bio Clean 911

John was great throughout the process for us. He was available surprisingly quickly, and was able to walk us through the whole process ahead of time, so we knew what to expect. We asked for a "best case scenario" estimate and a "worst case" and ended up *almost* at the top, but managed to avoid some of the issues we were worried about, so we still saved some money over the worse case scenario. Overall, I'm grateful that his team helped resolve the mold issue, fixed the root cause, and proved that things weren't *quite* as bad as we feared. I'll definitely have him back to work another part of my house once I've resolved a couple of unrelated issues.

John and his crew did a great job cleaning up some serious mold and water damage in our basement, and we had them come back two summers later to get the mold out of our patio room. Carlos and Tony put in a long day on the latter, and when they were done, the room was completely clean and mold-free. I heartily recommend Bio Clean 911 and wouldn't hesitate to call them again.

John Denny, owner, was fantastic to work with. I was in a difficult situation, as the St. Louis project had to be ordered from where I live in Denver. John's bid was competitive and he did everything promised, including starting and finishing on time. He was very professional and was a true pleasure to deal with. Clean on!

What a pleasure it was to work with John Denny and BioClean 911 for a mold remediation in our basement. John is a problem solver and his expertise, professionalism and responsiveness made this project run very smoothly for us. I highly recommend!

John, Dave and Tim all did a great job treating a relatively small, but very noticeable area of mold in our basement. Professional, personable and punctual (hey, I just came up with that!). They came highly recommended by a neighborhood online board and I totally agree! Thanks, guys!

Very efficient and trustworthy. We received an email update each evening with what had been accomplished that day and the plans for the following day.

My parents had major plumbing issue on Christmas. My mom called John first thing the next morning and he came over immediately to quote the work. He worked with the insurance company, was polite and thorough. Always was here with his guys. Couldn't be happier with the whole process.

Great job. Very efficient and trustworthy. We received an email update each evening with what had been accomplished that day and the plans for the following day.

The crew from Bio Clean 911 did some mold remediation work in my basement in November. The cost was WAY less than every other company I asked for bids and the scope of work was exactly the same. John, the owner, is very friendly and easy to work with. He was very thorough in his explanation of what kind of work would be done and he kept in very good communication with me.

His crew was polite and treated my home with respect. When the inspector came through and found a tiny bit of mold still in the basement, John and his crew came back out and cleaned it up within a day or so at no extra charge.

This is my first Google review, but there is a reason for this. I'm just often too lazy to tell when I get great service. This is the first time I have been so impressed by a company's professionalism, honesty, and willingness to work around my schedule that it would have been unfair and terrible of me to not write this review. John (the owner) and BioClean911 were simply a life saver. I, like many people in St. Louis, had sewage back up into my basement during the heavy rains around Xmas this year (2015).

After contacting him late on a Sunday night, he showed up Monday morning with a crew ready to clean. They were fast, efficient, polite, maintained professionalism at all times, and were very patient. It was emotional losing memories and contents collected over years that I had stored in the basement. Yet John's three man crew (plus himself) all kindly asked what items I wished to keep and which I wanted discarded.

They even gave me advice based upon their experiences quite a few times. Even the Nationwide Insurance adjusted agreed with their decisions when looking at the pictures. The work was done quickly, as well. Finally, John had his crew come out on New Year's morning (seriously!) so the fans and dehumidifiers were out of my way as soon as possible. The trash and discarded items were all gone the same day they pulled them out of my basement as they brought a dumping trailer so I wasn't left looking at a driveway full of possessions that I lost.

This really helped. John also has the necessary certifications (I had to look all this up--never had a sewer backup of this magnitude), and thoroughly documented the entire before/after process. This left me in a great position to get a maximum from my insurance company. He had complete write-ups to go with the photographic documentation, which made things much easier.

In short, I have never been so thoroughly impressed. I hope you take the time to give this company a chance if you ever are in need of emergency water/sewage/mold repair and help. It's just not often people are trying to help, not just to make a profit alone.

After receiving the news our house would need Mold Remediation, the hunt began for the best company to do the job right. Mold is a very serious subject. There is only one chance to get this right. I interviewed about 12 different companies for the job, going through them with a fine tooth comb. After all, this is a big investment and thats how we looked at it.

Who can we trust was the question! TRUST is a big word in this day and age. Many didn't fit the bill, AT ALL, after further review. I feared a botch job. The fact that we had been sick in our house due to the mold, it was of utmost importance. Then one day after months and months, I finally found the right company for the job. I instantly knew this was the one after meeting the owner John. Bio Clean 9-11 is a VERY professional company.

They actually went the extra mile for my quirky demands. They respected our property. They showed up on time, and got the job done. I wanted to say thanks again to the crew and owner!
