Your Local Mildew Cleanup Specialists
At Bio Clean of Utah, we specialize in professional mildew removal services for homes and businesses across Salt Lake City, Utah County, and the surrounding Wasatch Front. Mildew may start small, but left untreated, it can compromise air quality, damage building materials, and trigger health issues.

Whether it’s a lingering musty smell, discoloration on walls, or a moisture problem after a flood, we’re here to restore your property with confidence.
Why Ignoring Mildew Costs More Than You Think
Mildew isn’t just cosmetic—it’s a sign of excessive moisture and potential structural decay. Delaying removal can result in the spread of spores, worsening indoor air quality, and escalating repair costs.

What Our Customers Say
They were knowledgeable, timely and overall so great to work with. We highly recommend them for any mold mitigation.
Chris and Jose came to my home today to give me an estimate. They were friendly and super knowledgable. They gave me confidence that they are equip to solve a nagging problem in our home.
CALL BIO CLEAN BEFORE BUYING A HOUSE. These guys literally saved us from buying a moldy house. We bought a mold free home & are so much happier/healthier than we would've been. The house didn’t look/smell like it would be moldy at all, but when our home inspector (Josh at Spotlight- epic job on his part so shoutout to him too) found a trace of mold, he recommended we get professionals out to test. This was absolutely critical in making an informed decision, turns out there was a MINIMUM of $4500 to abate. Bio Clean was extremely transparent that their estimate could easily be a fraction of what the actual abatement would cost once the entire wall was opened, depending on the extent of the issue. Long story short, thank GOD we didn’t move in there, and if we hadn’t called these guys I don’t know if another company would’ve been as thorough or as honest.
The team was super friendly and explained everything in detail. I appreciate them telling me step by step the process. They were super respectful of our home. I would highly recommend this company.
They were super flexible working us into their schedule! I loved that they talked me through the results as well. Definitely would recommend!
Blake and the team at BioClean provided me and my wife with outstanding and remarkably thorough and immediate attention to an incident in which a broken water tank had resulted in water damage in our house. They were on the job immediately, calmly assessed the situation, provided an explanation of what had occurred, and developed a detailed action plan that they began to implement the next day ... and that solved our problem quicker than we could have anticipated. They provided peace of mind for what could have been a very difficult situation. They are also very cost effective. While we obviously hope we won't need to use BioClean again, if we ever have another similar problem, they'd be the only firm we'd call. In short, we can't recommend them enough to anyone who needs assistance with the assessment and/or remediation of water damage.
Bio clean came I and did a fantastic job cleaning and sanitizing a compromised area within our facility. Recommend them for disaster clean up.
Mike was so great! He came to inspect our mold issue in less than 24 hours, and offered us practical, cost-effective solutions for mitigating it. Highly recommend.
Great company to work with! Blake was super responsive and great about explaining the process. Can’t wait to get our project complete.
Christian was able to answer my questions and used his professional knowledge to help me out! I really appreciate your service!
Sam Ortiz was really professional and did a great job. Fantastic company. Would definitely use them again.
Christian did a great job, took a sample, walked us through the process and was super helpful.
Cristian and his team were very helpful and quick to get the work done. Mine wasn’t a big job but they took care of it quickly. Thank you!
BioClean of Utah: 5 Stars! Christian and Manny came quickly, stabilized the water damage, sealed off affected area with dehumidifiers and were extremely professional and courteous! Highly recommend this company! Don’t hesitate to call them!
Can’t say enough positive things regarding BioScience and the Flood Co. We had Memo and Mauricio to our home to remove some mold from the crawl space and add a vapor barrier liner. These guys are professional, diligent, and on-time with a high quality product and service. We are 200% satisfied!
Very responsive and nice to work with.
Memo did a great job! He was very knowledgeable, and answered all of my questions. I highly recommend Memo.
i highly recommend the bio clean team based on my experience - they were professional and extremely efficient.
I never had a chance to do business with Bio Clean but i had spoke with Blake about some issues i was having in my home. He knew i may not use his services but still went out of his way to answer my questions and make sure i was aware of what i was dealing with. Genuine responses and thankful to have spoken. 5 stars for being down to earth and helping others.
Daryl reviewed the results of a mold test we had conducted by another company and then did a physical inspection of our property. He was responsive, thorough, and professional. Other than a couple of minor spots where he gave specific advice for cleaning up, he did not find we had a serious mold problem. He did not propose extensive repairs/remediation when not needed.
Daryl was able to come out quickly and review some mold issues in the crawl space under the house we purchased. His expertise helped us mitigate costs on closing and he provided avenues on how best to treat and fix the problem. He was timely, efficient, proactive, and very insightful. The written report was informative and provided the correct avenues for recourse. I can't thank him enough for all the help he provided. During the course of closing on our house, we somehow forgot to pay the bill for the inspection. They did not hound us and were very gracious when I realized we had somehow missed paying the bill. Gave Amy a quick call and everything was set straight. Thank you again for everything!
Daryl help us with a mold inspection, he is knowledgable and informative, great company to work with. Thank you!
These guys rock!!
Super fast service, and told us exactly how to fix our mold problem and what tools would be needed! They do Fast and easy inspections 🙂
Daryl was amazing, on time, professional, and super helpful. I would recommend them to anyone!!
Bio Clean of Utah did an amazing job and thorough inspection of the mold issues I discovered in my condo. They explained the issue and possible causes for the problem in a very easy to understand way. I needed them fast as I was re-doing the floors in my condo and discovered the water damage covered up by the previous owner. They took care of the problem very quickly and professionally and made sure that everything in my place was protected while they were doing repairs. I highly recommend them for mold removal. They know what they're doing.
Your search is over. Your peace of mind is just a phone call away. I just had a wonderful experience with Bio Clean. Daryl himself came to our house to do a mold inspection, and did a thorough job hunting for mold issues and patiently answered all my questions. We found mold in two areas that I did not even suspect. Much to my relief though, those were the only problem areas and they were so small, that Daryl told me honestly that it could easily be handled as a Do-It-Yourself project. He told me exactly what to do. AND, he even referred me to an air duct cleaning company close by and suggested I have my ducts cleaned for better air quality in the house. I highly recommend Bio Clean of Utah.
I'm a Realtor in Park City and I've used Daryl at Bioclean many times recently for mold inspections for my buyer clients who have homes under contract. Daryl is very knowledgeable on mold and has been a great help for my clients in knowing more about the property they are buying. I highly recommend Bioclean.
We had a great experience with Bio Clean of Utah! They were easy to get a hold of and the lady on the phone was friendly and able to answer all of my questions. The workman arrived on time and was courteous and clean. He did a thorough inspection and was very informative and helpful. We are excited to continue to use this business to help us keep a clean and safe home!
Daryl Olsen has been helping me for years with my real estate clients and his knowledge, service level and workmanship has always been 5 star. Bio Clean of Utah just finished a mold removal job for a home that is pending sale. Nobody wants a mold problem in their home and Daryl took the time to explain how the cleanup would happen and answer their questions. His diagnostic and communication skills are excellent! Thanks Daryl!
These folks were awesome. They were very responsive and backed up their work. Great job!
My experience with this company is that they are honest and good to work with.
Wow, so impressed with this company! Kurt came out to inspect our home for mold. He was very professional, friendly, honest, and extremely informative. So glad we found this company! We will never go anywhere else!
We called Bio Clean to inspect for water damage and tell us if they saw or suspected mold. They did a really great job, used moisture detection, and showed us some things to keep an eye on. They went above and beyond and really helped us get some peace of mind for our house purchase.
Guided by the thorough, experienced hand of Daryl, Bio Clean salvaged the crawl space in our home, installing a sump pump system and sealing the moisture below a waterproof membrane. Two years later, he returned when called about an odor issue unrelated to the crawl space. The problem was analyzed quickly and recommendations were made. The word ‘trust’ comes to mind when thinking about Bio Clean.
We had a leak from our sink that ran down into our basement below. Daryl came out about an hour after I called and did a very thorough inspection! He showed me what he was doing and explained everything so that I would understand his concerns. He was kind, professional, and very competent. I felt very confident in his abilities and knowledge. I've had other restoration companies come out at other times and was worried they even knew as much as I did! Not so with Bio Clean...I trusted their work and was very pleased!
Fast, informative, nice, and professional. Came out to look at a mold problem with our home. Diagnosed the issue and informed us of the various ways we can go about taking care of it. Spent around an hour at the house and didn't charge us a dime. Will recommend and use these guys going forward. Thanks again!
I highly recommend this company! Very honest! Very informative! Thoroughly answered all of our questions! Daryl came out and did a mold inspection for us. He was very kind and extremely patient and taught us all we needed to know about our mold. Definitely worth the money! I have already been telling everyone that if they have mold problems or know anyone who does, call these guys! It’s super stressful to find mold in your house! But these guys definitely relieved a lot of stress. They’re fantastic and their customer service is amazing! Thank you Daryl for educating us so well and also everyone else for taking care of us! You guys are top notch! -Jennifer I.
I am so happy with this company! I called in worried about potential mold growing in my daughters room, not knowing anything about what I needed to do. The receptionist was informative and helped me decide what I needed to schedule. Sam came out the same day for an inspection. He was very nice and took the time to thoroughly answer all my questions. I would recommend Bio Clean to a friend.
Didn't even purchase something and the owner basically talked me through why I probably didn't need his services. That's the kind of honesty business needs - and he deserves the good reviews. He clearly knows what he's doing, such that he doesn't need to sell me on something I don't need.
Daryl and Sam were awesome. They were able to come out the same day and investigate a potential mold issue we had. They were honest and efficient, I could not be happier with the experience I had with them. They communicated well and were very responsive. Definitely recommend.
Very knowledgeable, they came to my house and did a thorough inspection. I would call them again!
Thank you for the swift reply, then jumping on the job and getting it done and a comment from another company who fixed a valve in the basement for us "wow you would have never had known you had mold or a flood . Great Job" So Bio Clean JOB WELL DONE
Bio Clean of Utah has proven to be invaluable to me as Park City realtor. I have a high-level of comfort recommending them for air-quality testing and most importantly, getting to the source of any problem (such as mold) and successfully solving all issues. I have worked with them on transactions involving $5,000,000+ new construction homes as well as older condominiums, all in ski country. Their no nonsense approach and obvious expertise is wonderful.
These guys are great wont go anywhere else
These guys did a great job. They came out and did a very thorough examination of our property. Finding no evidence other than a very small spot in the bathroom, they did not propose extensive and unnecessary repairs.
I had a wonderful experience with Bio clean of Utah. They were very kind and professional over the phone. The got there on time and followed through on everything they promised.
We needed a water damage inspection services for a home we are purchasing. The inspector found moisture in the basement ceiling. Daryl found the issue and advised on the next steps. Very detailed report gave us the information we needed to get it fixed.
It was a mess, they came in and got everything squared away. Keep up the great work.
Andy and Daryl of Bio Clean of Utah took excellent care of us. We had a flood in the basement and we were grateful for the quick and thorough response to the situation. They went above and beyond to help us out. They were professional, personable, and knowledgeable.
We had a mold problem in our house and Bio-Clean of Utah came and helped us and put our mind at ease. They were so very helpful and considerate. The technicians were kind and great. Thank you so much!
I had a very bad sewer back up in my basement. it was extremely unbearable. The crew responded fast and i was surprised how fast my basement was back to normal.
The team at Bio Clean of Utah is very professional and knowledgeable. The make sure to always get the job done the right way.
We had excellent service when Bio Clean of Utah repaired a leak in our basement recently. The problem was a sewer line leak. The company responded extremely quickly, and immediately determined the source of the leak. The company representative started the cleanup and drying out process. He also summoned their reliable plumber who came on the weekend, at no extra charge, to perform the repair. I was very pleased with the quick response, and the quality of the work was simply super. I can highly recommend the friendly and efficient employees of Bio Clean. Again, the service was excellent, and at a reasonable cost.
We recently had a leaky water heater that went unnoticed for about a month. This resulted in the walls surrounding the water heater growing mold. Bioclean of Utah came over and removed the mold and started the drying process right away. They did a great job restoring our home to it's pre-leaky state. Thank you Alex! You guys did great work.
Darryl did a very thorough and good job. Would highly recommend them. I was happy to know I had no mold

Mildew vs. Mold: What’s the Difference?
Many homeowners use “mold” and “mildew” interchangeably, but they represent different types of fungal growth—and require different treatments. Mildew is typically surface-level and powdery, appearing in damp areas like bathrooms, basements, or near leaky windows. Mold, on the other hand, can penetrate walls and materials, often producing strong odors and more severe health risks. Our experts know the difference and treat both with tailored solutions to prevent regrowth and protect your space.
How We Detect Hidden Mildew
Not all mildew is visible to the naked eye. Our technicians use advanced moisture meters, thermal imaging, and air quality tests to locate hidden colonies behind walls, under flooring, and inside HVAC systems. This thorough inspection process ensures we eliminate mildew at its source—not just on the surface—giving you long-term relief and safer indoor air.
Mildew Removal for Property Managers & Real Estate
Realtors and property managers across Salt Lake City and Utah County rely on Bio Clean of Utah to prepare properties for sale or rental. Mildew stains and odors can derail deals and decrease property value. We offer discreet, fast-turnaround cleanup that restores confidence and appeal to any residential or commercial space.

Eco-Friendly, Health-Conscious Treatments
At Bio Clean of Utah, safety is our priority—not just for your home, but for the environment. That’s why we use non-toxic, biodegradable cleaners that effectively kill mildew while being safe for children, pets, and those with respiratory sensitivities. Our solutions are strong on fungus but gentle on your family and the planet.
Preventing Future Mildew Growth
Removing mildew is only the first step. To prevent recurrence, we also identify the root cause—whether it’s poor ventilation, hidden leaks, or humidity issues. Our team provides expert guidance on improvements like dehumidifier placement, sealing cracks, or upgrading insulation so your home stays dry, clean, and mildew-free.
