About this company
Green Home Solutions of Mount Airy is a franchise location serving central Maryland, owned by Brian Preuss, a U.S. Army veteran with more than 20 years of military service. The company operates out of Mount Airy, MD 21771 and covers a wide swath of the region from Frederick and Westminster in the west to Bethesda, Rockville, and Silver Spring in the south.
What stands out here is the treatment approach. They use an EPA-registered, enzyme-based product called Oceanic that gets applied as a fine mist. The company claims it breaks down mold at a molecular level without requiring demolition of walls or materials in most cases. They also use containment with negative air pressure, air scrubbers, and HEPA-filtered vacuums during remediation, and recommend third-party post-treatment testing. Beyond mold, they offer mycotoxin testing, probiotic air purification, and crawl space encapsulation, which makes them more of a full-service indoor air quality operation than a straight mold shop.
Preuss has built a sizable crew. Reviewers regularly name Brandon, Cody, Jonah, Eddie, and Benjamin as field staff handling inspections and remediation. The About page quotes a sales team member, Lawrence P., suggesting the operation has dedicated sales and field roles. The franchise brand itself claims 25 years of experience nationally.
4.9 stars across 54 Google reviews is unusually strong. Only 1 review in the past 18 months fell below 4 stars. Multiple reviewers specifically note that staff did not try to upsell unnecessary services, which is a meaningful signal for a company that handles both testing and remediation.

Review consensus
Brandon is the most frequently named staff member, praised across multiple reviews for clear explanations, patience with questions, and detailed inspections. Brian (the owner) appears in several reviews conducting assessments personally, with reviewers noting he put on shoe covers and provided detailed findings. Cody is recognized for remediation work and air quality knowledge. Jonah drew praise for honest consultations without upselling. The remediation crew of Eddie, Shane, and Dante was called polite and hardworking. Kyle and Trevor were praised specifically for duct cleaning. A consistent theme is that staff take time to explain findings and do not push unnecessary services. Multiple reviewers mention that the team used containment during jobs and cleaned up well afterward.
1 found across 54 total reviews at 4.9★. The single recent negative review describes an inspection visit where the reviewer felt the inspector used only a cell phone flashlight to look for mold, did no formal testing, quoted a high price for remediation, and then charged $118 for the consultation. The owner responded in detail, stating that a separate high-powered raking light was used alongside the phone (which was for documentation photos), that a written inspection report with photos was provided, that formal mold testing was offered but declined, and that the $118 included late-payment fees applied after 90 days of non-payment on an originally lower invoice. The factual dispute between the two accounts is unresolvable from the outside.
The owner responded to the single negative review with a detailed, point-by-point rebuttal that addressed each specific complaint. This is a personalized response, not a template. With only 1 negative review out of 54, and an owner who engages substantively with criticism, the pattern suggests active reputation management grounded in actual engagement rather than deflection.

With 4.9 stars and only 1 negative review out of 54, this location has a strong track record. Ask for Brandon or Brian by name for your initial assessment. Clarify inspection fees and payment terms before the visit, and since they handle both testing and remediation, request that any post-treatment clearance testing be performed by an independent third party.
Keep in mind
- They do both mold testing and mold remediation. That means the same company identifying your problem is also selling you the fix. Ask whether they will accept a third-party test result, or request that post-remediation clearance testing be done by an independent lab.
- This is a franchise location under the Green Home Solutions national brand (OnAxis Franchising Group). Quality depends on the local owner and crew, not just the brand name.
- The service area listed on their website spans from Frederick to Bethesda to Bowie to Westminster. That covers a large geographic footprint. Confirm actual travel willingness and any trip charges for locations far from Mount Airy.
- One reviewer reported a dispute over a $118 inspection fee that included late-payment charges. The owner responded that the original fee was lower and late fees were applied after 90 days of non-payment. Clarify inspection costs and payment terms upfront.
- Their website uses the terms "removal" and "remediation" interchangeably but includes a disclaimer that removal claims should not be taken as a guarantee. Ask what specific outcomes they commit to in writing.
