About this company
BioClean is a West Haven, Connecticut restoration company that has operated since 1988. They handle mold inspection, remediation, air quality testing, basement waterproofing, water damage cleanup, and janitorial services across Connecticut and Westchester County, New York. They do both testing and remediation under the same roof, which means you should understand that dynamic before hiring them.
The service menu is unusually wide for a mold-focused company. Beyond standard mold work, they remediate mold in vehicles, remove allergens and pet dander, handle asbestos removal, and offer Halomist disinfection. They also do basement waterproofing end-to-end: foundation crack repair, French drain installation, sump pump systems, and crawlspace encapsulation. Carpentry services handle post-remediation rebuilds. Air quality testing starts at $425 for 2-3 indoor samples plus an outdoor control.

1 found across 76 total reviews at 4.7★. (1 found across 76 total reviews at 4.7★) One detailed 1-star review from November 2025 describes a homeowner who paid $7,500 for full remediation after BioClean said there was widespread Aspergillus on ceiling joists. The reviewer later hired an independent environmental specialist who concluded the original air test count of 5 did not warrant remediation. The reviewer also reported areas that were not properly cleaned after the initial work, requiring the crew to return. BioClean declined a partial refund, calling it a successful mitigation. The reviewer acknowledges making the decision out of fear. No owner response was posted.
BioClean did not respond to the only recent negative review. With a 0% response rate on negatives, there is no public engagement with complaints to assess. The conflict-of-interest dynamic is visible in the 1-star review: the company that tested also recommended and performed the remediation, and the scope of work was later questioned by an independent party.
Sal (inspector — positive). Tom (inspector/team lead — positive). Alex (project manager — positive). Elizabeth (office staff — positive).
Most reviewers describe a smooth, well-communicated process with fair pricing relative to competitors. The one negative review raises a real concern about scope recommendations when the same company does testing and remediation. Before signing a remediation contract, get your own independent air quality test and understand what your numbers mean.
Keep in mind
- BioClean does both testing and remediation. They have a financial incentive to find problems they can fix. Get an independent air quality test before agreeing to remediation work.
- One reviewer paid $7,500 for remediation that an independent environmental specialist later said was not warranted based on the original test results. The company did not offer a refund.
- They claim to service all of Connecticut and Westchester County, NY. Confirm response times and crew availability for locations far from their West Haven base.
- Air quality testing starts at $425 minimum. Remediation averages $300 to $4,000 but can run higher for finished basements.
