Don’t these make it worthless?
Inaccessible areas are those places the inspector wanted/needed to inspect but couldn’t get to. Even in an unoccupied house, there may be listings for areas of sub-floor or roof or with locked doors that keep the termite inspector out. If the place is occupied, furniture and stored stuff often gets in the way. You can help by clearing up before the inspection and having people available to move stuff as required. Read the report very carefully to see if the inaccessible areas are considered to be a risk that needs to be inspected. Sometimes this means opening up the surfaces to get access. Cutting access holes in timber floors or making holes to see behind the drywall plaster can make all the difference between finding the problem and living blissfully unaware until the damage is really extensive. Generally the basic/normal inspection is almost entirely visual, with a little bit of tapping and the use of a moisture meter. If you think you have termites, it may be better to go for an inspection with fancy tools (that partially overcome access issues) such as a termatrac radar unit or a thermal camera. If you have termites, then it is usual to have an invasive inspection and do everything you can to ensure adequate access.
If the inspection is done as part of a purchase, be very careful with mentions of inaccessible areas as these may be where the vendor is hiding something.
Bottom line is that if you are unhappy with any aspect of the inspection report, spend some time talking with the termite inspector to see what may be done. Often your fears can be overcome with a little more information than appears in the standard paperwork . .
