About Jon Rudolph
Meet Jon Rudolph
Before founding Inspections By Referral in 2002, Jon Rudolph built a career in geotechnical and civil engineering. He brings that expertise to every inspection, evaluating structural systems, soil implications, and building science with a level of knowledge and understanding few inspectors can match.
Over two decades, Jon has built his business almost on referrals — a testament to the trust he's earned with buyers, sellers, and real estate professionals across Northern Colorado.
He holds ASHI® Certified Inspector status, is a certified infrared thermographer, and is licensed for radon measurement in Colorado. Every inspection is performed personally by Jon.
"Since 2002, my business has grown one referral at a time, by telling people the truth about a house, clearly, calmly and within proper technical context."
