BioClean is a mold remediation company; its website lists mold removal, mold inspection, air quality testing, dehumidification and asbestos removal, and the company says it has been in business 38 years. A Patch headline reports that BioClean opened a West Haven location. On Google it holds 4.7 stars from 75 ratings. A 2023 customer said BioClean remediated an extensive mold problem in their attic, added baffles and rerouted 2 bathroom vents through the roof, and found no leakage around the new vents in heavy rain 10 days later. A 2024 customer said Sal traced their ceiling mold to a bathroom vent fan hose that was not properly installed and soffit baffles blocked by insulation. A 2022 customer said BioClean sealed two leaking basement cracks and added a french drain and an extra sump pump. A 2023 customer said a sump pump was installed after a tech rep evaluated their water issues. A 2025 one-star customer said BioClean recommended full remediation at a cost of $7,500, that areas they were told were cleaned still had visible dirt, and that an independent environmental specialist later told them the remediation was never needed; a partial refund was refused. A 2024 customer said the initial consultation, detailed billing and prompt replies were excellent, but a worker fell through the ceiling from an attic joist during the job, and a strong smell from the attic went unaddressed for almost a month without a callback. A 2024 customer said a technician never showed after a day of waiting, yet a bill came. A 2024 customer said waiting on a quote for remediating personal items held up their move for weeks. Connecticut lists its home improvement contractor registration, HIC.0657120, as active, held by BIOCLEAN LLC.

BioClean did an amazing job with our mold remediation. They were professional, thorough, and incredibly responsive from start to finish. The team explained everything clearly, showed up on time, and made what could have been a stressful situation feel completely manageable. You can tell they truly care about doing the job right. I highly recommend BioClean to anyone needing honest, reliable service.
The crew was super friendly, showed up on time, and knocked out the work we needed fast without any hiccups. They really know their stuff. Super happy with the results—definitely 5 stars and I’d call them again in a heartbeat!
Please Read Before Paying for Mold Remediation by any company. I’m sharing this experience so others don’t pay for mold remediation they may not actually need. I take responsibility for my part in reacting and making a decision out of fear, but what I learned afterward is important. Before I purchased my home, a mold air test was done. The raw count in the basement was 5 for Aspergillus — which I now understand is considered normal and was only slightly above the outdoor air which was 4. A swab also detected another common mold on a piece of furniture that was removed before I moved in. During the final walk-through, the basement smelled musty and there was a lot of a brown dirt looking substance on the wall where the furniture was removed by the seller. Due to my health sensitivities, I panicked and contacted BioClean immediately. BioClean came out and told me there was widespread Aspergillus on the ceiling joists and recommended full remediation: ceiling tile removal, HEPA vacuuming, encapsulation, negative air containment, air scrubbers, full-house cleaning (basement and upstairs), and a dehumidifier. Words like "alarming" were used which made me feel all the more scared and the need to have this done urgently. The cost was $7,500. I agreed again out of fear. Afterward, several areas that should have been cleaned were not cleaned at all. There was visible dirt even though I was told that they were. I took pictures and sent them in. Then, the cleaning crew was sent back. BioClean’s post-work test later showed a raw count of approximately 11, which is still considered a low and normal range. At the time I did not know that. They continued to offer the cleaning crew to keep coming back, but once trust is lost why would I ever want them to come back to my property. There were enough chances give. I asked for a partial refund, and was told they feel this was a successful mitigation. I then brought in an independent environmental specialist, who reviewed all lab results and inspected the home. His findings: -The original raw count of 5 did NOT warrant remediation ever. -According to the naturopathic/functional medicine health community, counts at this level are not considered harmful. -Cases that truly require mitigation typically involve raw counts much higher. -There was no swab testing or photographic documentation to support the claim of widespread Aspergillus. -If the ceiling were truly contaminated, the tiles would have needed to be removed, not just vacuumed. -He stated clearly that I NEVER NEEDED remediation. My advice to anyone dealing with mold concerns: Do not make decisions out of fear Always get an independent second opinion, and do research thoroughly. Learn what your raw count numbers actually mean and not by the company you are considering hiring. This applies to any mold remediation company — not just BioClean.
I do NOT recommend BioClean. They have held up my moving process for WEEKS and have made an already incredible stressful situation (me being permanently displaced due to mold in my rental) even more stressful. I cannot plan my move until I get a quote for remediation of my personal items and every day when I call I'm told that "the technician is working on it". I now have to scramble to find someone else so I can move in 4 days. I am beyond frustrated and upset.
Bio clean claimed that they completed service after they had made me wait around all day and the technician never showed. But the bill came. It took a conversation, but they were able to figure out that the technician did not show. Even still, they have sent me emails constantly asking to give them a review. With no way to opt out of the emails. Here is your review.
