In a tough real estate market, like we have now, tensions run high. Agents work hard to put together deals. Most agents do not have a problem with an issue, cited on a home inspection report, as long as it is valid and put in reasonable perspective. However, building houses is complicated and there are many safety guidelines that the properly trained home inspector looks for that might go "unseen" by someone who is not familiar with the job and requirements.
For that reason, when certain not so obvious problems are noted at an inspection, it can save later bickering if the inspector provides enough information to further explain or "prove" the point. Here is an example. At least half of the time around here, the B-vent from the gas furnace or the water heater is buried in attic insulation. Granted, insulation is not that easy to burn, but it is defined as a "combustible." Therefore, the inspector should cite this as a problem and tell the client that there needs to be at least 1" of clearance from the B-vent to any combustibles including the insulation.
Because this is so commonly seen, and little known as a problem to anyone except inspectors and HVAC techs, I have had agents question that any such clearance is required. I prefer not spending time on the phone or Email if I can avoid it. If I can get close enough to the B-vent to see the manufacturer's installation tag, I put that photo in the report as well. Case closed.
It is not possible, or necessary, to explain in great detail every issue found at a home inspection. But, in general, clarity of information, writing and documentation can be helpful when preparing a home inspection report that is to be deciphered by non-inspectors.
