What this listing says
Southeast Florida homeowners who want an owner-operated firm where a PhD biochemist personally supervises every remediation and includes drywall rebuild in one contract.
Best for
- Homeowners in Broward County and Southeast Florida dealing with mold after water damage who want remediation, rebuild, and clearance testing handled by one contractor.
- Real estate buyers or sellers facing a mold finding during a transaction who need fast turnaround and a transferable warranty for closing.
- Anyone with unexplained indoor air quality symptoms tied to AC or ductwork who needs the system restored, not just surface-cleaned.
- Homeowners who want a fixed-price quote that includes post-remediation lab testing and a two-year warranty, rather than open-ended billing.
About this company
Certified Mold Free is a family-owned operation in Davie, Florida, run by Gary and Linda Rosen. Dr. Rosen holds a Ph.D. in Biochemistry from UCLA and a B.S. in Chemistry from UF. He personally supervises every job. Linda handles initial consultations and manages client communication. They do both mold assessment and remediation under one roof, which Florida law permits because they also hold a state building contractor license.
The standout here is what they bundle. Remediation quotes include drywall rebuild, post-remediation air testing sent to a third-party lab, and a two-year transferable warranty. They use strictly chemical-free methods and carry $5 million in environmental insurance. They also restore AC systems and ductwork through a partnered AC contractor, and they handle yacht sanitation. They do not offer 24/7 emergency services, a deliberate choice they say is about retaining skilled technicians.
The Rosens have completed over 2,000 remediations across 20-plus years. Gary has published seven books on mold topics and has served as a litigation support witness for over 15 years. They also run Florida's mold assessor and remediator licensing training courses, which account for a significant portion of their Google reviews. Linda holds licenses as both a mold assessor and an independent insurance adjuster.
4.9 stars across 118 Google reviews with no negatives in the last 18 months is unusual for any contractor. The volume includes both remediation clients and training course students, so the rating reflects two different lines of business. Still, the remediation-specific reviews are uniformly positive, with multiple clients noting that Gary recommended against unnecessary work.

Review consensus
Linda Rosen draws the most frequent praise for fast response times, patience during consultations, and willingness to answer questions at length before any commitment. Gary Rosen is praised for his knowledge, honesty, and hands-on involvement. Multiple remediation clients note that Gary recommended against unnecessary work or referred them to a simpler fix. Bill Seitz, a repeat client across two properties in Coconut Grove and Pinecrest, praised consistent quality. Jenny Aday described the crew as thorough from first call through completion. Ronnie Sue L credited them with same-day mobilization after the April 2023 Broward County flood. Training course students consistently praise the depth of material and Gary's teaching style.
0 found across 118 total reviews at 4.9★. No negative reviews found in the last 18 months. The only sub-5-star review in the dataset is a single 4-star from Dean Stamper (February 2024), a restoration industry professional who found the training course effective but noted that Gary can be opinionated about restorers.
The review base splits into two distinct groups: remediation clients and mold licensing course students. Both groups rate the company highly, but for different reasons. Remediation clients emphasize honesty, pricing, and quality of work. Training students emphasize Gary's teaching ability and Linda's administrative support. This dual-business model means the review volume is higher than a pure remediation company of their size would typically generate.
Linda Rosen (co-owner, client intake and consultation — consistently positive). Dr. Gary Rosen (co-owner, job supervisor and trainer — consistently positive). Dean Stamper noted Gary can be opinionated with industry professionals during training (neutral/minor).
This is a strong pick if you want an owner-operated firm where the principals are directly involved in your project. Ask for Linda when you call. If you are concerned about the testing-and-remediation conflict, get an independent mold assessment first and bring the report to them for a remediation quote. They will quote from a third-party report without requiring their own assessment.
Keep in mind
- They do both testing and remediation, which is a conflict of interest. Florida law allows this because they hold a building contractor license, but you should understand that the same company diagnosing the problem also profits from fixing it. Consider getting an independent assessment first.
- They do not provide 24/7 emergency water extraction or flood response. If you have an active leak or flooding, you will need a separate emergency dry-out contractor first.
- A large share of their Google reviews come from students who took their mold licensing courses, not from remediation clients. The 4.9 rating reflects both audiences.
- They encourage you to get three quotes, which is good advice. Their website claims prices in the industry vary 3x to 5x for the same scope of work.
