Website Link Exchange

I recently updated my website home inspector links and found that only 6 out of 135 have gone out of business or dropped their websites over the last 7 years. I also found that only 4 out of the 135 offer any warranties or guarantees. Any thoughts as to why?

Most seasoned home inspectors don’t offer warranties or guarantees.
