Unmatched Credentials. Complete Protection.

The GreenWorks Standard​

Most inspection firms settle for the bare minimum. GreenWorks holds the licenses and certifications most competitors can’t staff, and the multi-state, firm-level authority most can’t legally hold.

Our Credentials Are Your Strongest Protection

An inspection is only as reliable as the authority standing behind it. Here is how GreenWorks’ industry-leading licenses give buyers, sellers, and real estate pros total confidence on every deal.

The TREC Advantage

Earning a TREC License requires nearly 200 hours of rigorous technical training, comprehensive state exams, and continuous regulatory oversight.

While smaller firms rely on apprentice-level oversight, GreenWorks has 49 directly licensed TREC Professionals, setting an operational benchmark most local companies simply cannot match.

The InterNACHI Technical Rigor

An InterNACHI certification isn’t just a website badge; it requires passing a comprehensive technical exam, demonstrating rigorous report-writing competency, and logging 24 hours of mandatory continuing education every single year to stay sharp.

While many local companies feature the logo based on a single owner’s certification, GreenWorks has 54 InterNACHI Certified Inspectors on staff. When our inspectors evaluate a roof, electrical panel, or foundation, they follow strict international standards designed to catch defects standard checklists miss.

Firm-Level Asbestos & Mold Licensing

Most home inspectors are legally required to stop, step aside, and tell you to hire a specialist the second they spot suspected mold or asbestos, costing you time, extra vendor fees, and days on your option period.

GreenWorks holds firm-level environmental licenses. When mold or asbestos is suspected, you don’t get referred out to a third party. One of our own licensed specialists can perform asbestos and mold inspections, testing, and consulting, directly under one roof.
