Beyond the basics, which specialized certifications (like mold, radon, or pool inspections) helped grow your business?
NRPP (https://nrpp.info) radon certification moved the needle for me; I made it stick by advertising ‘48‑hour results by 6 p.m.’ and auto‑emailing the report to agents the moment the monitor docks — only worth it if you’ve got enough calibrated monitors. @Evan, did you go NRPP or NRSB?
