It may seem more convenient to hire a single person to handle both home inspections and related repairs, but that doesn't mean it's necessarily in your best interest. A home inspector who's been hired to repair defects is likely to find more potential flaws then one who's simply performing an inspection. While the majority of home inspectors can tackle both of these tasks while maintaining a high ethical standard, there's always the risk of running into one who's less than scrupulous. In fact, the American Society of Home Inspectors forbids its members from soliciting repair work based on the results of an inspection they performed [source: Dawson].
To protect your pocket book, keep inspection and repair work separate, and beware of inspectors who offer their services for other tasks.
