What this listing says
Richmond-area homeowners dealing with mold tied to crawlspace moisture or HVAC contamination, especially those who want an IICRC-on-site crew that insists on third-party post-remediation testing.
Best for
- Richmond and surrounding Virginia communities needing mold remediation from a company rooted in HVAC and air quality work.
- Homeowners with crawlspace mold or moisture issues who also want encapsulation done by the same crew.
- People with CIRS or severe mold sensitivity who need item-level small particle cleaning with full documentation.
- Commercial facility managers — schools, hospitals, government buildings — who need remediation crews that can work around operations.
- Buyers who want a company that requires independent third-party testing before and after remediation.
About this company
Kohmar is a family-owned air duct and HVAC cleaning company in Richmond, Virginia, that expanded into mold remediation. Brothers Brian and Jason Kohring started the business in 2011, and the name combines their surname with their uncle Bob Marsh's. Their core identity is duct cleaning — mold remediation is a newer addition, launched with a dedicated page in early 2026.
What stands out on the mold side is their small particle cleaning service, designed for people with CIRS or high mold sensitivity. Technicians place rooms under negative air pressure and individually wipe down every object — documenting each item with photos. They use remote monitoring on their negative air systems during containment, and they exclusively use AprilAire dehumidifiers. Kohmar also states on their website that they insist on third-party Post Remediation Verification rather than grading their own work, which is unusual for a company that also does testing and inspection.
The company holds NADCA, IICRC, and Aeroseal certifications. Their website claims more NADCA-certified technicians than any other company in Virginia. They intentionally limit mold jobs to 1-3 per week so crews can focus on a single project without overlap. They do not handle rebuild or structural repairs — they subcontract that work to local contractors.
4.9 stars across 810 Google reviews is exceptional volume for a Richmond-area restoration company. The overwhelming majority of reviews relate to duct cleaning and dryer vent work rather than mold remediation, which reflects that mold is still a newer part of their business.

Review consensus
Reviewers consistently name specific technicians — Gavin appears in at least four reviews for being knowledgeable and methodical. Charleston gets repeat mentions for thorough explanations during initial walkthroughs. Ahsan and Tone are praised together for being detailed, respectful of the home, and informative. Jeremiah and Andrew are called out for being pleasant, efficient, and accommodating. Karla in the office is mentioned for smooth scheduling. Buzz and Andrew drew praise on a crawlspace mold remediation job for being knowledgeable and answering questions. Jaylen and Anthony were highlighted for their enthusiasm. Kyleigh and Robert impressed a dryer vent customer enough that she felt obligated to write about it. The dominant themes are punctuality, willingness to explain the process, and care for the home (shoe covers, floor protection, not scraping walls).
3 found across 810 total reviews at 4.9★. Matt Henson's crew visited for a dryer vent job, told him within ten minutes the PVC run needed replacement, promised a same-day estimate, then went silent for two weeks despite two follow-up calls — leaving him without a working dryer. No owner response. Kyle reported that a crew member used his personal face cloth to clean something, his tweezers went missing, and technicians entered his bedroom twice without knocking during a work meeting. The owner responded by noting Kyle's roommate (who hired the service) had no complaints and that they tried contacting Kyle without success. Mary Kay Romaine left a 1-star review with no text. Beth Musick gave 3 stars, saying the 2025 visit was not as good as her 2020 experience — ceiling vents were reinstalled incorrectly and had to be redone by a return crew, and promised follow-up photos were never sent.
The negative reviews share a follow-through theme rather than a workmanship theme. The dryer vent estimate never arrived. The promised photos never came. The vents had to be reinstalled. For a company that does excellent first-impression work — showing up on time, explaining the process, protecting floors — the pattern suggests the back-end process (post-visit communication, quality checks, promised deliverables) does not match the front-end experience. The owner response rate on recent negatives is only 25% (1 of 4), and the one response engaged with specifics rather than using a template, which is a positive sign for the responses that do happen.

Ask for Buzz or Andrew if your project is mold-related — they are the names that show up in remediation-specific reviews. Confirm in writing when you will receive your estimate, your post-remediation photos, and your third-party test results, because follow-through after the crew leaves is where this company has stumbled. The on-site work itself is consistently praised across hundreds of reviews.
Keep in mind
- Kohmar does both mold testing/inspection and remediation, which is a conflict of interest. They acknowledge this on their own website and say they insist on third-party Post Remediation Verification — ask for the name of the independent testing firm they use and confirm they will not perform both the testing and the remediation on your project.
- Their primary business is air duct cleaning, not mold remediation. Mold services launched recently. Ask how many mold remediation projects they have completed and whether your specific situation (attic, crawlspace, living space) matches their experience.
- They do not handle structural repairs or rebuild after mold removal. You will need a separate contractor for drywall, framing, or finishing work, which Kohmar coordinates through subcontractors.
- Their service area stretches from Richmond to Virginia Beach, Charlottesville, Fredericksburg, and Washington, DC. If you are on the outer edge, confirm scheduling availability and whether the same crew handles your project start to finish.
- One recent reviewer waited two weeks without receiving a promised estimate for dryer vent work, and follow-up calls went unanswered. Pin down response timelines in writing before committing.
