No, the painter will usually not do that. You should look for someone who does siding repair work. Get that done first and then have the painters come after the siding has been repaired. If you have any DIY skills, you can take a look on-line. I believe that "This Old House" has some videos about how to repair siding. You might be able to do some of it yourself. If you aren't comfortable doing it yourself and don't have any other recommendations, you can go to
