About this company
VioClean is a family-owned environmental firm based in Swampscott, MA that handles mold remediation, water damage restoration, sewage cleanup, and indoor air quality testing across the North Shore and Greater Boston. They have been operating since 2005. Owner Trung Nguyen holds an ACAC accreditation and built the company around non-toxic, all-natural cleaning products.
What stands out is the breadth of their environmental testing. Beyond mold inspection, VioClean tests for particulate matter (PM2.5 and PM10), formaldehyde, volatile organic compounds, carbon monoxide, radon, and water quality issues including lead, bacteria, and heavy metals. They also offer carpet and upholstery cleaning, HVAC cleaning, and contents restoration. They frame their work through a three-step process: assess, identify the source, then remediate. They accept bitcoin.
Trung started VioClean as a green carpet cleaning company and expanded into emergency restoration. The company supports the MSPCA and breast cancer prevention through Know Breast Cancer. They hold an A+ BBB rating, three Angie's List Super Service awards, and claim to arrive within an hour of a call.
At 4.8 stars across 72 Google reviews with zero negatives in the last 18 months, VioClean has an unusually clean review record. The volume is modest but the consistency is notable — nearly every reviewer with text mentions fast response times.

The overwhelmingly positive record may partly reflect the company's size and volume. With a small team handling a manageable caseload, service consistency is easier to maintain than at larger operations. The shift in named staff from Trung (2017-2021) to Marcello (2024-2025) suggests the company may be transitioning day-to-day operations while Trung remains the owner.
Trung Nguyen (owner — praised repeatedly for responsiveness, communication, and hands-on work). Marcello (field lead — praised for being hardworking, friendly, and having integrity). Fabiano (assistant to Marcello — praised for being hardworking). Ryan (staff — praised for knowledge, professionalism, and flexibility).
VioClean's track record is strong for emergency water and mold work on the North Shore. Ask for Marcello or Trung by name. Because they do both testing and remediation, get an independent mold assessment before committing to a remediation contract.
Keep in mind
- VioClean does both testing and remediation, which is a conflict of interest. A company that finds the mold also profits from removing it. Ask whether they will accept a third-party test or recommend an independent assessor.
- Their mold service area stretches from Nashua, NH to Quincy and Roxbury, MA — a wide geographic spread for a small firm based in Swampscott. Confirm crew availability and response time for your specific location.
- The website is heavy on templated city-specific pages with similar content, which makes it hard to distinguish actual capabilities from SEO filler. The About Us page has more substantive detail.
- With 72 reviews spread over nearly a decade, the review volume is moderate. Most of the textual reviews describe water damage emergencies rather than mold-specific work.
