We are refinishing a 1920's home in South Texas area. It is currently covered with old asbestos siding. We now are debating hardi plank vs premium vinyl siding. I would like to keep the look as much as possible to the original but really want to make it more energy efficient. We are leaning toward the vinyl as we think the insulation is better. Any suggestions? Also 1 siding company said they would put the vinyl over the asbestos and another said they would remove the asbestos first??
