Diligent

What Diligent does

Diligent is a privately held, Nashville-based home inspection and building diagnostics firm operating exclusively in Middle Tennessee. The company offers more than 20 inspection and testing services spanning core residential home inspection, commercial inspection, pre-drywall, mold assessment, radon, termite, sewer camera, stucco/EIFS, structural, lead/asbestos, water, pool/spa, and short-term rental (STR) inspection. Its underlying methodology combines human visual inspection with diagnostic instrumentation including thermal imaging cameras, gas leak detectors, and moisture meters, executed by certified inspectors (ASHI, EDI, CMI, CRT, HITA) and led by owner Michael Conrad II.

The business model is direct-to-consumer and transactional. Pricing is quote-based and disclosed at booking; payment is collected after report delivery via online invoice links (Visa, Discover, American Express, MasterCard). Customers are home buyers, home sellers, and real estate agents who book through the website, by phone (615.200.8220), or via email. No subscription or recurring revenue model is offered. The company's marketing strategy is content-led, built around an educational blog, an A-Z home inspection glossary, a homeowner handbook resource, and 'The Business of Homes Podcast' — a multi-platform podcast featuring local realtors that functions as a realtor-channel and brand-building asset. Active social presence on Instagram and Facebook, plus 1,000+ cumulative five-star reviews (793 specifically on Google), reinforce the local brand position.

Diligent is owner-operated with no disclosed parent company, no institutional investors, and no external funding rounds. Operating geographies are confined to the United States (Tennessee), with a headcount in the 11-50 range. Three sister companies under common ownership — RadTest (radon), Perimeter Pest (pest control), and Riverside Environmental (environmental testing) — extend the service ecosystem and reinforce a one-stop-shop positioning, though they operate as separate legal entities.
