Guardian Radon Removal LLC
OH
Retained directory description
Guardian Radon Removal LLC lists crawl-space encapsulation on its radon-mitigation page, alongside radon and ventilation services. Its company materials describe serving Cincinnati, Dayton and surrounding Ohio communities. Confirm the specific crawl-space scope and property coverage directly; general regional marketing is not proof that every service is available at every address.
The company contact page lists 513-216-5941 as its main phone and 513-939-5954 as an alternate. The reviewed material establishes service areas, not a physical office street. No office city or map location is inferred from those service-area names.
For a crawl-space proposal, ask which barrier, sealing and ventilation tasks are included and how those tasks relate to the radon-mitigation design. Request a written scope covering testing, access and maintenance responsibilities. Ask whether water-entry repairs must be handled separately before the installation. This directory does not adopt the company’s promotional guarantees or verify any certification claims.
Company sources reviewed October 20, 2026. Services and general coverage are company-published statements, not independent credential verification or an endorsement.
