This project highlights one of the problems associated with only replacing some of your siding. My client replace 2 walls of siding on his home with Hardie Beaded Cedarmill lap siding because it most closely matched the existing siding. Once the rest of the siding deteriorated and needed to be replaced the siding he used was discontinued. We were able to get a similar product but it was in Hardie's Dream Collection and costs 3 times what the original siding cost. We then finished the siding we replaced with SW Latitude paint.
