No home inspector is perfect. Hidden or concealed issues exist in every home, and some conditions simply cannot be detected during a visual, non-invasive inspection. Mistakes can happen because inspectors are human. We care deeply about getting it right, we work hard on every inspection, and we stand behind our work — but it is important to be honest about what an inspection can and cannot be.
A home inspection is a generalist evaluation of the property’s current condition. We are not a licensed plumber, electrician, HVAC technician, roofer, structural engineer, pest control specialist, chimney sweep, and sewer contractor all rolled into one. Each of those trades represents years of specialized training, certification, and daily hands-on experience in a single discipline. We do not possess the combined knowledge of all of those trades, and no single inspector does.
If you want the deepest possible certainty about any one system, the answer is to hire the licensed trade professional for that system — a plumber to pressure-test the lines, an electrician to open every junction box, an HVAC tech to run full combustion and refrigerant diagnostics, a structural engineer to calculate load paths, a roofer to lift every shingle. You could hire all of them. Most buyers do not, because the cost and coordination of assembling that many specialists before closing is rarely practical. That is exactly the gap a home inspector fills: one trained professional giving you a thorough, honest, big-picture assessment so you know where to focus your time and money.
Furthermore, home inspection companies are not insurance companies. Our professional fees are designed to cover a thorough, professional evaluation of the property’s current condition — not to act as an underwriting service for future repairs. We do not have the profit markup necessary to provide a full-service warranty as part of our standard inspection fee. That is why we strongly encourage bringing in the appropriate licensed trade when our findings point to a concern that warrants it.
