Probably the biggest problem with asbestos cement siding, that is still in place today, has to do with areas that have been cracked or damaged. This was the early cement-based siding, with asbestos fibers. Everyone hears the word "asbestos" and gets nervous, however asbestos siding itself is not airborne or friable unless one starts mechanically tearing into it or sanding on it. Here is the real problem: The material, from day one, was brittle so it is unusual to find it in pristine condition. It was a good long-lived product, but as installations of the siding go back more than 30 years, mechanical damage from people and mowers has usually occurred at some location or another on many to most of the homes that have this siding. That takes a toll when it is such a brittle material to begin with. Now, here is a fact: If the siding is still in good shape, there is really no essential reason to replace it in my view -- unless people do not like the look. In fact, even minor repairs can usually be done with a modern cement fiber siding that has a similar look. However, if the siding is cracked, damaged in many places, has gaps, then it is not doing its job and probably should be replaced. When that is the case, it brings up issues that are not risk factors with other sidings. Because, if the asbestos is going to be removed from the house, then it must be treated as hazardous waste and specific safety guidelines kick into effect. In this state a homeowner can do the work, but only when regulated. I know a state enforcement officer who has had people arrested for removing asbestos siding in an unsafe manner. That would be a bad way for a buyer to begin his or her tenure at a new home. Below is one of many seriously damaged areas at this home. The damage here was extensive enough that the home needed new siding. The cost of disposal then became a major consideration for the buyer who was buying the home "as is."

The most I have ever heard about asbestos is if not disturb it is suppose to be safe, but is disturb is where you run into problems. I would have that issue taken care of and I am not sure if you will need to just replace that board with something compatible or remove the stuff. Good luck and I will watch to see what happens.
